I am like so smart!

Aw shucks....

Back From Christmas Vacation

Yes, my friends, I'm finally back from Christmas vacation. I traveled about 2500 miles in total through sunshine, snow, and ice. The trip to SLC was uneventful, but traveling from SLC to Las Vega for my brother's wedding was quite an adventure. There was a huge blizzard the day after Christmas and many of the mountain passes we drove through were icy. Near Parowan (in UT) I started fishtailing on the ice, but managed to bring the truck back under control. It was pretty scary, though, and my husband decided to take over driving at that point. I was shaking for ten minutes after that. He drove the rest of the way to Las Vegas white-knuckled until we got past St. George where the roads were clear. We drove back to Dallas on Sunday and it looks like we left just in time since now there's snow in Vegas!

It was nice not to talk about science for a week. The only science-related things I remember saying was briefly explaining my thesis project to a couple family members. After that, they would nod their head and move quickly on to another topic. Feel the love.

I took quite a few pictures, but as I don't have a digital camera, the film will probably languish in my camera bag for months until my husband gets fed up and insists I develop the pictures. He's much better at stuff like that than I am. I do have one finished roll, so I'll try to develop it this week so I can post some pics on this site.

Some of you may have noticed that I went to Las Vegas for my brother's wedding. No, it was not an Elvis-chapel-o-love type wedding if that's what you're thinking. It was a traditional Mormon (LDS) wedding at the Las Vegas temple with the traditional reception at a local LDS chapel afterwards. There are actually quite a few Mormons in the Las Vegas area. They make up about 12% of the population of southern Nevada (for perspective Mormons make up 1-2% of the population nationwide). Brigham Young sent settlers to Las Vegas in 1855 to build a fort there, the first non-Native American settlement in the valley. More history of Las Vegas here.

Anyway, in an LDS marriage ceremony, you'd better make sure you're marrying the right person, because we don't marry "until death do us part," but "for time and all eternity" i.e. even after death. Really, I think this is a beautiful, romantic concept for those of us with good marriages. But if the thought of being with your spouse forever seems horrifying to you, then LDS temple marriage is not for you.

Merry Christmas Blogosphere!

I'm off to visit the family in Utah, so I won't be posting again until Dec. 29th. Everyone have a wonderful Christmas and/ or Hannukah. I'll leave you with some beautiful pictures of my "hometown" Salt Lake City, Utah. If you ever happen to be in SLC during the holidays, I recommend going downtown to see the Christmas lights at Temple Square. With the lights and the Christmas concerts every evening, this is the perfect holiday date.

This week's New Weblog Showcase

Here are my pick's for this week's The Truth Laid Bear's New Weblog Showcase:

My Word: The Politics of the Lord of the Rings
Politics plus Lord of the Rings commentary? We lovesss it, yes we do Preciousssss.

Pragmatic Conservatism by Dan K. O'Leary: Bush, Saddam, and Howard Dean
Dan is a fellow Alliance member and I also enjoyed his commentary on Howard Dean. This guy is fearless in the face of Deanbots.

Spam Town: Spam of the Week
At first I was thinking, who wants to read a blog about spam? But then I read a few of his posts, and there's quite a bit of useful info for avoiding spam. The entry post also had an amusing bit of spam where the sender was looking for stuff like a warp generator and a series time transducing capacitor. Wacky stuff!

ROTK Review

Well my friends, I stayed up all night on Tuesday, Dec. 16th to see The Return of the King at midnight. I went to sleep at 4 a.m., woke up at 11 a.m., lurched into lab around 2 p.m. and little work was done. But boy, was it worth it!

Unfortunately my husband, who has a real job, was unable to attend so that means I get to see the movie at least two more times. Yay!

Let me begin the review by saying that those that haven't read the books and even Tolkien purists (like myself) will enjoy this movie (given you've seen the first two). The acting is superb, the cinematography and special effects are stunning, and there's plenty of action for the guys and some romance for the ladies (there could have been more, see below).

The movie starts out with Smeagol and Deagol fishing in a boat. Deagol finds the Ring by chance and Smeagol kills him to get it for himself. We see the physical and mental transformation of Smeagol into Gollum over th 500 years he has the ring. Gollum is twice as evil in this movie as in TTT as he leads Frodo to the gluttonous spider Shelob. I really think Andy Serkis deserves some recognition for his superb work. Sean Austin and Elijah Wood are also excellent in their depiction of Sam's fierce protectiveness and Frodo's exhausted determination to destroy the ring.

We then pick up the story with Aragorn, Gimli, Legolas, and Gandalf arriving at Isengard. The fellowship splits up again after Pippin looks into Saruman's palantir, and he and Gandalf rush off to Minas Tirith. The Rohirrim gather their forces to journey to fight the armies of Sauron at Minas Tirith. Aragorn receives his sword Anduril (Narsil reforged) from Elrond and decides to follow the paths of the Dead to recruit an army of spirits that are in debt to the heir of Isildur for desertion.

I love the depiction of Eowyn's character by Miranda Otto. She goes from joy to complete despair and then the flatness of depression as she discovers that Aragorn doesn't love her. She disguises herself and rides to war with Merry. She kicks major butt in the battle of Pellenor Fields as she takes down an oliphant and the Witch King.

Unfortunately, two of my favorite scenes involving Eowyn were cut. The first is the scene where Eomer discovers that both Theoden and Eowyn are dead (he thinks). I saw this scene in the trailer and the depiction of Eomer's grief as he hold is sister is heart-rending. I don't know why it was cut because it's one of the most emotional scenes in the book.

After the battle, the scenes in the House of Healing are also cut out and we go right to the scene where Aragorn decides to take their armies to the Black Gate. It's a little disjointed because we don't know what happens to Eowyn or Faramir. We just see her at the end with Faramir, but we don't know how they get together. All I can say is that BOTH of these scenes had better be in the extended version, or I will be most seriously displeased!

The rest of the movie is pretty true to the book except the plundering of the Shire and the death of Saruman are not depicted. I expect to see more of Saruman in the extended version.

The battle at Pellenor Fields is awesome, but at times too busy to see all that's going on. Perhaps Jackson wanted to give the audience the same sense of frantic helplessness that the warriors probably felt as their comrades are falling by the hundreds around them.
I know how the book (and thus the movie) ends but at times I was wondering how are the characters going to make it through all this.

One final comment: do not drink a Mr. Pibb (don't tell my bishop) an hour or two before the movie even if you think you need it to stay awake! Towards the end, I didn't know if I would make it to the end. The ending is quite drawn out, but I think it works well.

On a scale of 1-10 (10 being the highest), I'd give ROTK a 9. I'm docking a point for leaving out my two favorite scenes. If it were up to me, I'd give ROTK the Oscar for best picture, Miranda Otto for best supporting actress, and Sean Astin or Andy Serkis best supporting actor. But it's not, so some lame artsy fartsy movie will probably get all the honors. Humph!

On Being a Female LDS Scientist

So where do I begin? First of all, there are not many LDS scientists to begin with and I’m not exactly sure why. There are approximately 2000 LDS scientists currently according to this link. I don’t know how many of those are women. What’s interesting is that Utah produces more scientists per capita than any other state for the last 60 yrs, 75% of whom are LDS. Of these, 83% percent classified themselves as strong believers and 90% of these felt that their religious beliefs and science theories could be harmonized. I think these statistics show that there is a great love for learning amongst LDS people and that most don’t believe that science and religion are mutually exclusive. Here’s a great paper on science & LDS scientists by Robert L. Miller.

Recently on Times & Seasons, there was an entry that posed the question of why there are few LDS women in the “hard” sciences and philosophy. I think LDS culture and theology play a large role. At an early age, it’s drilled into our heads that as women, our primary role is mother. We are told by our leaders over and over that we should stay at home with our kids and not work outside the home unless we have no other choice. So we have to plan ahead while we’re in high school for an education that will prepare us for employment that is family-friendly should we have to work.

I believe that most LDS women, if they attend college, plan for careers that involved only a 2 or 4-year degree. A woman can graduate with a bachelor’s by the time she is 21 or 22 if she attends full-time. This is the prime age for marriage and raising a family. I was almost 23 when I married, so I had a year to work after getting my degree. I was planning on going on a mission, but I met my husband before I submitted my papers. The majority of LDS women are getting married either before or right after they get their bachelor’s degree. And then most have children within a year or two of getting married. There simply is no time for graduate school.

It’s very difficult to attend school, even part-time and care for young children. I’m unique in that I had some health problems that prevented me from having children right away. I decided to use the time I had to further my education. Science is not a family-friendly (or female-friendly) career area. In order to get a position as a professor at most universities, one must have a Ph.D. and a post-doctoral fellowship or two. It can’t be done part-time either because it’s like having a full-time job plus overtime. Typically one takes classes the first two years while working the rest of the day and then one work full-time (and then some) in the lab until the thesis is complete.

The problem isn’t just that there are few LDS women in science, but there are few women in general in science (at least at professor levels). Only 10% of tenured professorships in the U.S. are held by women (link here) even though 25% of PhDs are awarded to women. Most of the women’s advocacy groups claim this is because of discrimination, but I’m not so sure. There may be some institutions where sexual discrimination is a problem, but I have never experienced it. I think the reason is that most women, when faced with choosing between family and a career in the sciences, choose family.

When looking at first year graduate students classes, there are about as many women as men, but over the years, many drop out. Some get married, some have children, and some decide they don’t want to do science anymore. When one finally gets to the post-doc level a lot of women have decided that they don’t want to go further. They might branch out into other fields such as science writing, technology transfer, patent law, etc. These are the prime childbearing years and once one steps off the academic career track, it’s hard to get back on. If a woman stops to have a child or two, then she has to choose to either stay at home with them until they are school age or shuttle them off to daycare at a young age and go back to the lab. The latter alternative is out of the question for most LDS women.

But things are getting easier. There are now day care centers on most campuses. There are more part-time post-docs available. I have met a few female professors that are able to juggle running a lab and caring for their children. But they have had to make big sacrifices. Either their research or their time with their children suffers. Mostly, the children grow up in daycare. If I were unmarried, none of these things would be an issue and I could pursue a position as a professor without any guilt.

Besides the issue of family, some LDS people wonder how one reconciles LDS theology with the theories of science, especially the theory of evolution. I’ll talk more about my ideas about evolution later. But to me science and religion, at least Mormonism, are not incompatible, but rather complementary.

Believe or not, most biological research has nothing to do with evolution directly. I could think the theory of evolution is totally bogus and finish my thesis project with no problems from my committee. Evolution is usually only an issue when relatedness of genes or fossils are being studied. For instance, biochemistry as a discipline involves taking apart a biological machine like a cell and trying to see how all the different parts work independently and then trying to reconstitute the cell. The evolutionary history of all the components is not that important. But the relatedness of an uncharacterized human protein compared to a well-studied homologous mouse protein can give insight into how the former protein functions.

I personally favor intelligent design in part because of LDS theology, and also because living things, even single-celled organisms, are incredibly complex. There are thousands of different enzymatic reactions that take place in various signaling networks that can have hundreds of different component proteins. These networks are robust to perturbations, but are also highly sensitive to targeted mutations. This is a strong indication to me that life did not evolve randomly, but was somehow organized by an outside force.

I’m fascinated by the complexity of nature. To me, science is like taking apart the little machines God has put together, and then trying to put them back together. Scientists are always trying to duplicate what God (or nature) has done. It makes me laugh when some Christians accuse LDS people of blasphemy because we believe we can be like God one day when that’s exactly what we as humans are doing every day. We are creating, organizing, and re-engineering things to make them better, to cheat death, and explore beyond our small planet. No other creatures of God do what humans do.

Yet, there seems to be a significant bias in the scientific community against those that are religious. Most scientists I know are agnostic or atheist and treat religious people as less intelligent and sophisticated. Scientists, who are supposed to be objective and deep thinking, can be just as bigoted and shallow as anyone. We all bring our unique worldviews with us. There was a time when it was unusual that a scientist did not believe in God. I hope that one day religious scientists will be the

The Butcher of Baghdad Has Been Nabbed!

American 4th infantry division forces caught up with Saddam near Tikrit (hat tip LGF).

It's an early Christmas present for the people of Iraq and freedom-loving people everywhere. Merry Christmas!

My picks for this week's New Weblog Showcase

For political blogs, I cast my votes for:

Anti anti war: The War in Iraq will be a success
I liked their style of commentary, although it had an odd layout for a blog. What really impressed me was their spanking of a competing left-leaning blog. That's pretty gutsy.

Locke, or Demosthenes?: Iraq contracts
This blog looks great and is well-written.

I didn't vote for any non-political blogs because none of them interested me and one was in German, so I couldn't read it anyway!

How Geeky Are You?

No biology-based blog could be complete without a Geek Test. I scored 22.87968% - Geek. I was kind of disappointed that I was only a geek as opposed to a super geek. I think I would have scored higher if there were more science-related questions. See how you do (hat tip geeklife.com).

Science Journal Round-up

Science News

Berkeley accused of biotech bias as ecologist is denied tenure
Nature 10 Dec 2003 - Apparently Dr. Ignacio Chapela, an anti-GM ecologist, is upset that he was denied tenure. He claims that it's because Berkeley is biased (towards research that generates money as opposed to research that generates zilcho dinero). Gee, could it be that he didn't get tenure because he published diddley squat?! Sorry, buddy, in science being a nice guy just doesn't cut it.

Hot Research

Molecular Memories That Survive Silicon Device Processing and Real-World Operation
Science 28 Nov 2003 - Chemists from UC Riverside and N. Carolina State have developed an organic molecular method for storing information. They show that porphyrin-based molecules fused to Si(100) can withstand the extremes of temperature (up to 400 degrees C) and ~10^12 read-write cycles. Also, multi-bit information storage is possible with these molecules since they can undergo multiple redox states.

A Protein Interaction Map of Drosophila melanogaster
Science 5 Nov 2003 - For fly biologists out there, this group has attempted to map all the protein to protein interactions in the fly proteome. The main problems I have with this paper is that the resolution of the figures in the paper is poor and that they used two-hybrid experiments to test for interaction between proteins. Two-hybrid experiments often elicit many false positives. But they did assess the reliability of the interactions based on experiments done on yeast orthologs. The results may be useful for finding novel protein-protein interactions and then lead to more extensive testing.

MICROBIOLOGY: Chemical Warfare and Mycobacterial Defense
Science 12 Dec 2003 - Researchers from Cornell University have discovered a key component of how M. tuberculosis, one of the deadliest pathogens, eludes destruction by the body's immune system. M. tuberculosis is typically inhaled into the lungs where it is taken up by macrophages, immune cells that typically engulf and kill foreign cells. M. tuberculosis avoids destruction by blocking fusion with lysosomes (organelles fill with acid and digestive enzymes) and resisting the toxic effects of nitric oxide (NO) which is produced as part of the immune response.

The proteosome of M. tuberculosis was shown to be the primary component of NO resistance. Proteosomes are macromolecular protein structures found in prokaryotes and eukaryotes. They function in the turnover of cellular proteins by degradation of misfolded or damaged proteins. In M. tuberculosis, the proteosome detects damaged proteins and is also able to repair them, conserving resources. If some proteins comprising the proteosome are mutated, M. tuberculosis is less virulent and easier for the macrophages to fight off. The M. tuberculosis proteosome may serve as an important target for development of additional tuberculosis drugs to treat drug-resistant strains.

Viewpoints: Tragedy of the Commons (a.k.a the sky is falling)This week's issue of Science has a special issue on managing world resources to commemorate the 35th anniversary of the publication of Garrett Hardin's essay, "The Tragedy of the Commons." Dr. Hardin was a zero-populationist. I'm sure what he said back in 1968 seemed radical, but now his views are eerily commonplace. I'll save a fisking of his essay for a later time, when I'm feeling particularly grumpy. Anyway, this collection of viewpoints on Hardin's theme may interest those of you that may wonder where the U.N. gets their policies on reproduction, global warming, management of global resources etc. It appears that scientists from Hardin's school of thought are making international policy and it should scare those of us that value freedom and personal responsibility.

My first Precision Guided Humor Assignment as a member of the Alliance of Free Blogs

Campaign Slogans

Well, it seems that the Alliance of Free Blogs has lots of assignments. Usually, I'd be too lazy (and supposedly busy with lab work) to do them, but this one has lots of humor potential.

Here's my campaign slogans for the 9 Democratic candidates:

Joe Lieberman Vote for me! Only the jolly Emperor Palpatine can save the Republic!

Howard Dean Vote for me, the irrationally exuberant Grumpy dwarf.

Dick Gephardt I like corn AND NASCAR, vote for me!

John Kerry Vote for me and there will be a ketchup bottle in every kitchen! (Oh, there is already?) Nevermind, I fought in 'Nam!

John Edwards Vote for me because I'm the best-looking of them all.

Al Sharpton There's actually no reason why any of you crackers should vote for me, but I DID host SNL.

Wesley Clark I couldn't lead a herd of monkeys into battle, but I'd make a great President.

Carol Moseley Braun I'm the best candidate you haven't heard of!

Dennis Kucinich Vote for me! Only I can defeat the evil brain-sucking greeyons from the planet Smee!

Oh no! What have I done!

So I joined the Alliance of Free Blogs because it seemed like the thing to do. Also, it appealed to my sense of mischief-making.

And I just learned how to do blockquotes.

Healing Iraq Posts Pics of Bagdad Demonstration Against Terrorism

Go Iraqis! Although this demo won't do much to stop the fedayeen and Al Qaida thugs, at least it shows the world that the people of Baghdad support the coalition and want to be a free nation. Read the whole article.

Healing Iraq

Science and the Middle East

I was under the impression that the science community was supposed to act as unbiased, objective observers. You know, just focus on our nerdy little projects and refrain from injecting politics into our research. Unfortunately, some scientists feel the need to mix politics and science when it comes to the Israeli-Palestinian conflict.

Last year a group of scientists from Europe (mostly the UK) organized a boycott of Israeli researchers. One of them was Richard Dawkins, a famous evolutionary biology (and one of my least favorite people). Here's the letter they published in the Guardian. They also tried to persuade the E.U. to boycott Israel, but luckily the E.U., in the interest of invested money of course, declined to participate.

Nature magazine, published in the UK, was a primary battleground in the debate. Here's a link to the web focus page that lists all the numerous letters and articles on this subject. In the October 2 2003 edition of the magazine, the cover (seen below) featured the Israeli wall.

Hmmm... based on this cover, what side do you think Nature is on? I thought this cover was completely inappropriate because typically the cover of a science journal is reserved for the hottest research of that issue i.e. something scientific, NOT political. But in reading Nature's commentary on science policy, I've noticed a decidedly left-leaning and sometimes anti-U.S. tone in their commentary.

However, in that October 2 2003 issue, the article about the challenges facing Palestinian and Israeli scientists was surprisingly even-handed. Here's an excerpt:

Many Palestinian researchers reject the idea of boycotting Israeli science. "It's counter-productive," says Abdeen. Even among Palestinians who support the idea of an economic boycott on Israel, there is unease about the idea of extending protests into the scientific arena. In towns such as Nablus and Hebron, however, some researchers support the actions of those foreign academics who have refused to work with Israeli scientists. Despite his own willingness to work with Israelis if the collaboration strengthens Palestinian science, Khatib is among their number. "Pressure must be exerted on Israel," he says. "I support the boycott because it can enhance movements in this direction."

Such comments are distressing to Israeli academics, especially those involved in collaborations with Palestinians. There is a saying in Israel that reflects the country's love of debate: "put two Israelis in a room, and you'll get three opinions". But this definitely does not apply to discussions about the call for a scientific boycott. "You're not going to get three opinions on that," says Jonathan Gressel, a plant biologist at the Weizmann institute. "I don't think it ever helps to keep scientists out of science for political reasons." His colleague Geiger agrees: "This breaks with one of the most cherished and important features of science: that it is international and non-political (emphasis added)."

Science magazine, published in the U.S., had a more low key approach. No covers. No barrage of letters. They printed two small articles, both on efforts of Israeli and Palestinians to collaborate despite the political conflict.
ISRAELI-PALESTINIAN RESEARCH: As Mideast Peace Process Lags, Science Endures
ISRAELI-PALESTINIAN COOPERATION: Building Bridges in a Battle-Scarred Land

Now, I'm not saying that scientists shouldn't be involved in politics and state their opinions openly. I've got strong opinions myself that regularly conflict with those of my coworkers. However, these political views should be set aside when you do science and interact with scientists from other countries. To me, what Dawkins and his buddies have done is nothing less than bigotry. It smacks of the same sort of anti-semitism that infected German science during the rise of the Nazis. Also, I think boycotts do more harm than good. Look what happened in Iraq. Saddam lived like a sultan, while his people starved and non-military research ceased.

Anyway, incidents like the science boycott are what happens when smarty-pants experts in one little area, e.g. evolutionary biology, think that they are also experts in everything else, including foreign policy. Dawkins et al. should try to look at both sides of the story, write their whiney little letters to al-Guardian (not Nature), and get back to work!!!!

Axis of Weasels Gets Their Just Desserts

FOXNews.com - Politics - White House Backs Limiting Iraq Reconstruction

I just have one comment about this. Hah, hah (a la Simpsons)!

On a more serious note, it looks like Saddam and his cronies will get their just desserts.

Iraq War Crimes Tribunal Established

The tribunal has said they may try Saddam in absentia, but they have not decided on whether the death penalty will be reinstated.

Time for Some Furry, Asia Cuteness

I just realized that I haven't posted any pics of my kitty, Asia. So I give you Asia, Queen of the Pants and all she surveys.

Here she's just helping herself to some Cap'n Crunch.

While Vision of Weblogs Danced in My Head

You know you're addicted to blogging when you start having dreams about blogging. It's almost scarier than dreaming about vengeful giant fruit flies ripping your limbs off one by one, and then gouging your eyes out. Almost.

Thanks everyone!

I guess my blog was voted the best non-political blog in last week's New Weblog Showcase. I'm stunned and humbled by that honor. I thought for sure that Tiffany from Blown Fuse would win. She is really funny.

Anyway, many thanks to those that voted for me. A special thanks to Denita from Who Tends the Fires for her kind words and encouragement. I added her to my sidebar under Fly Friends. I would have posted links to everyone that voted for me as a thank-you, but I'm not savvy enough to figure how to find those links from last week's competition. I guess I should have thought about this yesterday. Drop me an email if you can help me out.

Biology Lab Primer - Of glowing green-eyed flies, calcium, and brains

So I said I'd talk about how my research on fruit flies has a practical application. The eye of a fruit fly is very different from mammalian eyes. They are basically arrays of tiny motion detectors, designed to sense movement of a predator rather than to discern the intricacies of color and form like human eyes. The electrical responses of fruit flies are 100 times faster than those of human eyes. That's what makes them so darn hard to swat with a fly swatter.

While insect vision is interesting in itself (especially if you want to be able to swat them effectively), what I'm really interested in is how nerve cells or neurons function in all animals. The photoreceptors in the fly eye are actually modified neurons. They receive an input (light) and transmit an output (histamine) at their synapses. Flies are ideal model systems to use to study neurons because they have simple nervous systems, they are easy and inexpensive to maintain, there are many mutant flies that can be tested, and you can do experiments on them that you couldn't do on humans. Yes, ripping the eyes off a human being and jabbing electrodes into the freshly dissociated eyes IS unethical and illegal in case you were wondering.

The fly photoreceptor cell signals in a way that is similar to certain types of neurons in the mammalian brain. This pathway contains a receptor, the protein rhodopsin (also found in mammalian eyes) in this case, on the surface of the cell that responds to an external stimulus, light. Once light activates rhodopsin, rhodopsin then turns on a whole cascade of other signaling proteins. The proteins in the signaling cascade had different functions. Some turn on other proteins, some turn others off. Some breakdown certain biological compounds, while other synthesize new compounds. Some proteins undergo conformational changes that allow them to transport other molecules into or out of the cell. These proteins are called ion channels. The end result of light stimulating rhodopsin results in ion channels opening and allowing high concentrations of calcium from outside to rush into the cell. High amounts of calcium are eventually toxic to cells so it is then pumped out of the cell at the end of the signaling event.

But high calcium inside of cells is needed for other signaling events that help make vision and other neuronal processes more efficient and dynamic. Adaptation, which occurs when you enter a darkened room, is a calcium-dependent process. Memory is also calcium dependent. And more and more research is showing that its not just the amount of calcium that's important for neuronal signaling, but also the location of the calcium influx. Localized calcium influxes (also called calcium microdomains) have been shown to occur in the inputs and outputs of neurons. There are billions of neurons in the human brain, and each neuron can have thousands of inputs and outputs. Now combine that with localized calcium signals and the dynamic range and computational power of the brain is enormous. Memories are probably stored by the coding of various inputs and outputs along with the localization of calcium signals.

Proteins in the inputs and outputs of neurons are organized into little signaling complexes so that they can respond to local increases in calcium. In fly photoreceptors, there are scaffolding proteins that bind together ion channels and calcium-dependent signaling proteins. If you disrupt the complex by mutations in the scaffolding protein, the ion channels still function and calcium flows into the cell, but the calcium-dependent proteins don't function properly. We think this is because they need to be close to the source of calcium, the ion channels, in order to do their job right.

So my thesis project involves testing this idea by measuring the calcium microdomains in normal flies and in flies where the protein signaling complexes have been disrupted. I've made flies that have calcium "detectors" fused to different proteins in the signaling complex. The calcium "detector" is a protein that fluoresces in the presence of calcium. I can image these "detectors" inside a fly photoreceptor cell with a microscope and a camera. The brighter the cells, the more calcium is near the "detector."

Falling asleep yet? That's your biology lab lesson for today. Here's a picture of me taking images of fly photoreceptor cells in the dark.

101 Uses for Science magazine

Use #12 - fly swatter
This is very handy in the fly room where gazillions of flies can get loose.

Use #34 - coaster
Since we don't have any real coasters in the break room, science journals work great. They're also good for placemats (use #44).

Which Founding Father Are You?

Take this quiz to find out. I am:

Support the People of Iraq in Their Fight for Freedom

Visit this site if you want to get a banner for your blog that shows your support for the people of Iraq as they fight against the Saddam loyalists and their terrorist buddies. I added one to my sidebar. Sign the petition too. My all time favorite picture that represents my hopes for the Iraqi people is below. I just love the sheer joy and hope expressed on this little girl's face.

101 Uses for Science magazine

Use #27 - doorstop
Yesterday I saw that the lab next door was using Science magazine as a doorstop. I guess their paper got rejected by the editors. Bummer. I'm sure they can put Science to a better use, such as toilet paper (use #54).

Microbes on Parade: The New Weblog Parade

So I entered my modest little blog in the New Weblog Showcase from The Truth Laid Bear's as a desperate bid for at least one or two readers to give me some useful feedback. Apparently you start out as a lowly microbe and then as you get more links, you rise higher on the evolutionary blog scale. I was at least hoping to get as high as a fruit fly, but today I'm apparently a slithering reptile. Sssssssspectacular, my precioussssssssssss!

I've been putting off voting for my favorite new weblogs so I could see all the candidates, but I know I'll forget to vote if I don't do it soon. So here are my picks:

For best political weblog, I vote for dangerous liberty: Al Franken on Book TV Anybody that bashes Al Franken so enthusiastically is ok in my book. I've never thought Franken was funny, even when he was on SNL. He's a loudmouth braggart, and I just can't stand him. I really tried to keep an open mind and vote for the blog with the best design and writing style, but I couldn't get past some of the left-leaning rhetoric without blowing a gasket. So I'm biased, sue me.

For best non-political blog, I vote for Blown Fuse: Bestiality is a no-no. This blog is highly entertaining and has a dizzying variety of topics. The title of the sample post worried me a little, but it was an amusing, if not disturbing anecdote about an oversexed cocker spaniel.

My second choice is Times & Seasons: What Power? although I thought they could have chosen a more interesting post to represent the blog. It's main focus is Mormon theology, so like the good little Mormon that I am, I'm giving them my support. However, I haven't had a lot of time to read all the articles in depth, so I'm not saying I endorse their representation of Mormonism. However, they have quite a few people that seem to be quite knowledgeable about wide variety of topics. But I would recommend that those not familiar with Mormonism start out with the basics here before diving into this blog.

Also, don't forget to vote for your favorite blogs here in the 2003 Weblog Awards.

Science Journals Round-up

BIOTERRORISM: Anthrax Powder: State of the Art?
Here's a disquieting article about the origin of the spores used in the 2001 anthrax attacks from Science magazine (subscription required, hat tip LGF). Basically, the theories on the origin of the anthrax fall into 2 categories: it's a homemade crude extract or it was made in a state-of-the-art (read state-sponsored) facility. I remember when the analysis of the spores found in the Senate offices revealed that the anthrax contained a milling agent, silica, and electrostatic charges. These results seemed to indicate it was a high-tech job because of the spores' high aerosolibility.

Then for some reason the FBI denied that the sample contained silica and seemed to think that the culprit was a "lone-wacko," Dr. Hattfill. This article discusses in more detail the analyses of the samples and the attempts of the government to reproduce the samples. Basically, Army experts were unable to reproduce the sample by using a crude, lab-in-the-garage (without silica) approach, but got really close when they used silica and a top-secret ingredient (probably a coupling agent that gave the spores electrostatic charge). So what's up with the FBI? They led a wild-goose-chase through Dr. Hatfill's home and a nearby pond. Why? What advantage would they gain by covering up the fact that the spores were produced by a highly sophicated research facility?

Personally, I never bought the "lone wacko" theory. As soon as the I heard about the anthrax, I thought "from Iraq with love." I don't have any evidence for my hunch except that we know Saddam had an anthrax weaponization program at one time. Those spores can sit around in storage for decades maybe even hundreds of years without losing potency. The spores sent through the mail were probably a test run. Fortunately, although a lot of people were freaked out, few people died, and our nation did not grind to a halt. People exposed to the spores were given antibiotics, a mail screening process was developed, and a vaccine was already available.

If I were the conviving little terrorist(s) who did this, I would say the test run was a failure. The next step would be to either develop a better method of spore dispersal (e.g. aerial release) or use a more communicable pathogen like smallpox. Both possibilities are rather frightening. So basically, this article leaves me wondering who's responsible for the anthrax attacks and will we ever catch them?

Update: Here's a website that lays out all the evidence in the anthrax case. A lot of it I haven't heard about before (via LGF).

Update: I doubt that the info from the above site is that reliable. In his profile of the anthrax sender he states, "the refiner/mailer probably watches Bill O’Reilly on the Fox News Channel." What evidence supports that assertion? Come on! At least he has an exchange with the author of the above article, Dr. Gary Matsumoto that's kind of interesting.

And now for something completely different....

Jokes activate same brain region as cocaine
A study at Stanford University showed that the same brain centers that are activated by cocaine are also stimulated by funny jokes or comic strips. Functional magnetic resonance imaging (fMRI) showed that one particular brain region, the nucleus accumbens, is stimulated by the release of the neurotransmitter dopamine. Looks like laughter is the best medicine (or dope) after all.

Geek-o-rama - ROTK

Only 14 days until the release of Return of the King! If only the actor playing Aragorn, Viggo Mortensen, wasn't such a loser. Personally, I'd rather have brains than beauty. But Legolas (a.k.a. Orlando Bloom) is rather nice to look at.

Why I Hate Pop Science

Now I know I'm going to sound like one of those elitist intellectuals that I despise when I say this, but the science you read about in most popular magazines and newspapers ain't science, baby. The very worst pop science ideas are ones that try to scare you into doing or not doing something based on flimsy evidence.

Here's an example that I just made up, but I wouldn't be surprised to see it in this month's issue of Ladies's Home Journal or Reader's Digest. The headline of the article would blare something like "Twinkies Can Cause an Early Death!!!!!!" The article will open with an interview with a thoughtful young mother who says, "I never thought that something so tasty and delightful to my adorable children could cause so much damage to their fragile little bodies."

Then the article will site a study in some obscure medical journal where out a group of 50 people, those that ate a twinkie every day were 20% more likely to die of a heart attack before the age of 50 than those that did not eat a twinkie every day. Of course, some people might conclude that twinkies are harmful to your health and will cause you an early death.

However, this study would show, like most of the studies in JAMA, a correlation, not a causation. There may be a correlation between eating a twinkie every day and dying of a heart attack before age 50, but there is no evidence that twinkies actually cause heart disease. First of all, I would look at the size and composition of the sample group. If the sample size is small I wouldn't trust any conclusions the researchers came up with. Also, the sample group should accurately represent to whom the study would apply. Does the sample group contain a representative number of males, females, racial types, age groups, body types etc.? In the imaginary twinkie study for instance, I could have stacked the cards by selecting all the young, healthy, athletic people for the control group(non-twinkie-eating), and all the overweight, old people with bad hearts for the twinkie-eating group.

Also, how can one control for just the twinkie eating behavior? I think it would be nearly impossible to select a sample group that had everything in common except for the twinkie-eating behavior. The twinkie-eaters are more likely to engage in other unhealthy behaviors like not exercising, eating 3 bags of potato chips daily, and super-sizing their McDonald's combos while the non-twinkie-eaters are more likely to eat tofu and practice yoga. But that shouldn't affect my decision to have one lousy twinkie today.

And of course, there's always the possibility that the researchers or the magazine editors tweaked the statistical results to favor their position: that twinkies are bad for you. So then the food police decide cite the twinkie study and lobby for higher taxation or outright banning of twinkies and other "dangerous" foods.

Now I don't have a problem with clinical correlational studies. They are useful for showing trends in conjunction with other studies, such as combining a more representative twinkie study with studies on many different types of foods to show that in general a healthy diet is better for you. But I think that many lobbying groups and media sources use studies like my phony one to promote their own agendas.

Here's some examples:

Study shows 9/11 cause heart attacks.

Center for Science in the Public Interest Issues list of "Better and Worse" Snacks for kids

California to Sue EPA over Global Warming

All three of these article were written by Steven Milloy who runs a website called JunkScience.com. He does a great job of exposing the flaws in many of these studies and the motivations behind the groups that use these flawed studied for their pet causes.

Another webpage that might be of interest to those of you who want to be able to eat your dingdongs and twinkies in peace is The Center for Consumer Freedom. Now I'm going to get a Snickers bar. Just try and stop me, you food Nazis!

Oh No! Not again, Jimmeh!

Since I really didn't want this to be a political blog, I've been trying to refrain from bringing up politics. But alas, I am a news junkie, and with LGF and others to keep me informed of all the pols' shenanigans, I just couldn't resist. Our illustrious ex-Pres Jimmeh Carter has once again opened his mouth and inserted his muddy peanut-farming foot (via LGF).

In a interview with the NYT "Mr. Carter, defeated in his quest for re-election by Ronald Reagan in 1980, speculated that "had I been elected to a second term, with the prestige and authority and influence and reputation I had in the region, we could have moved to a final solution."

Um, I don't think Mr. Carter realized how bad that sounded. I mean, come on: Israel, Jews, final solution, Adolf Hitler. Ring a bell, Jimmeh?

Viva les comments!

Since I'm trying to get back into my work at school this week, I thought I'd start by adding a comments section to this blog instead of working. Yay! Now I'll see if anyone will have something useful to say.

A Thanksgiving Funeral for Grandpa

I've been out of town for the funeral of my grandfather. He passed away on Saturday after his health started to fail about 3 months ago.

Despite the somber occasion, I enjoyed myself. Marriages and funerals are the only times when most of the family gathers together. I got to see aunts, uncles, and cousins that I hadn't seen in years. I also met an aunt and her son, my cousin, that I had never met before. One of my uncles flew all the way from Shanghai, China to attend the funeral. We also enjoyed Thanksgiving dinner together.

LDS or Mormon funerals are quite unique. The life of the deceased individual is remembered, but also life after death and the Plan of Salvation are greatly emphasized. Mormons believe that death is just a progression to another stage of being. The spirit is temporarily separated from the body until they are reunited in the resurrection which will occur when Christ comes a second time. Also, family relationships will continue in the afterlife if one is obedient to the commandments of God.

So the body is dressed and buried in a traditional manner except that the burial plot is consecrated. This means it is blessed by a member of the Church that holds the Melchizedek Priesthood, and it is set aside for the temporary resting place of the deceased for the later resurrection of that person at the second coming of Christ.

My grandfather was a WWII vet so he got a veteran's funeral complete with a 21 gun salute, a flag-draped coffin, and "Taps." I played a piano arrangement of the hymn "O My Father" (click to listen to midi version played on page) since my mother had laryngitis and was unable to sing. My grandfather had requested that she sing at his funeral, so I hope he wasn't too disappointed. The lyrics of the hymn are below:

O my Father, thou that dwellest
In the high and glorious place,
When shall I regain thy presence
And again behold thy face
In thy holy habitation,
Did my spirit once reside?
In my first primeval childhood,
Was I nutured near thy side?

For a wise and glorious purpose
Thou has placed me here on earth
And withheld the recollection
Of my former friends and birth;
Yet oft-times a secret something
Whispered, "You're a stranger here,"
And I felt that I had wandered
From a more exalted sphere.

I had learned to call thee Father,
Thru thy Spirit from on high,
But until the key of knowledge
Was restored, I knew not why.
In the heav'ns are parents single?
No, the thought makes reason stare!
Truth is reason; truth eternal
Tells me I've a mother there.

When I leave this frail existence,
When I lay this mortal by,
Father, Mother, may I meet you
In your royal courts on high?
Then, at length, when I've completed
All you sent me forth to do,
With your mutual approbation
Let me come and dwell with you.

Lyrics: Eliza R. Snow, 1804 - 1887.
Music: James McGranahan, 1840 - 1907.

This hymn reflects the basic beliefs of Mormons regarding the afterlife and I think it's very apropos for a funeral.

My grandfather's death also made me realize that we should make the most of the time we have with our friends and family. I would give anything to have been able to visit with him one last time to let him know how much I love him.

Science Journals Roundup

Note: A subscription is probably required to view these articles. You can get a free 6 month subscription for the journal Nature here.

Science & Politics (I just can't get enough):

Medical journal under attack as dissenters seize AIDS platform
Nature vol. 426, pg. 215 (20 November 2003)-
Apparently, some AIDS researchers are upset that the British Journal of Medicine (BJM)has been regularly publishing the letters of a very small minority of scholars that deny HIV causes AIDS. They feel that the BJM may be assisting in the "dissemination of disinformation," but the editors of BJM assert that the letters are free speech.

I'm all for free speech, but sometimes it gets irritating trying to reason with the unreasonable. For example, I once corresponded with an"AIDS revisionist" that was not a trained scientist. I was able to tear his arguments to shreds with the overwhelming evidence found in thousands of research papers supporting the HIV/AIDS theory. However, this individual was very dogmatic and resistant to logic, even if the data was published in respected peer-reviewed journals. So it was a waste of my time to even address his arguments since he ignored the scientific evidence. So I can understand why AIDS researchers would get tired of having to refute the same half-truths and outright lies over and over again. Maybe the BJM should just restrict the number of letters from the AIDS revisionists (there's only a handful of actual scientists in the group) they print to one or two a year. That way the real AIDS experts don't have to waste valuable research time responding to these yahoos.

Cool Research:

Plant development: Leaves by number
Nature vol. 426, pg. 237 (20 November 2003)-
The regular arrangement of leaves around a plant's stem, known as phyllotaxis, occur in a pattern known as the Fibonacci series as shown below.
In this study, the authors discover that proteins involved in the transport of the plant hormone, auxin, are involved in phyllotaxis. Leaves bud where the auxin concentration is the highest and formed leaf buds acts as auxin sinks. Thus, new leaf buds form higher up on the stalk where they are spaced away from the existing leaf buds.

Nature vol. 426, pg. 237(20 November 2003)

Whale of a catch blows hole in family tree
Nature vol. 426, pg. 219 (20 November 2003)-
A new species of baleen whale was discovered by marine biologist Tadasu Yamada. Eden's whale (B. edeniis related to Bryde's whale, but when Shiro Wada, a molecular biologist at Japan's National Research Institute of Fisheries Science in Yokohama, analysed enzymes in the liver and muscle of those specimens, he found dramatic differences.

Developmental biology: Gender benders
Nature vol. 426, p. 241 (20 November 2003)-
Insulin receptors were shown to be required for development of male sexual organs in mice. When all three insulin receptors were knocked out, the male mice developed ovaries instead of testes. Triple-mutants are very difficult to make and analyze since knocking out single genes is often lethal. So, hats off to these researchers, but I sure wouldn't want this as a thesis project.

Design of a Novel Globular Protein Fold with Atomic-Level Accuracy Kuhlman et al. design a new protein fold with a unique sequence and topology. They then solved the structure of this novel protein using x-ray crystallography and NMR (nuclear magnetic resonance) and showed that it was nearly identical to their predictions. Why did they do this? Because they could.

Central Lynch Pin in Psychosis
Science vol. 302(5649), 21 Nov 2003, pp. 1412-1415.
Amphetamines, PCP, and LSD all cause pychosis similar to that seen in schizophrenia, but they act by different mechanisms. Svenningsson et al. show that these three signaling pathways converge on a single protein, DARPP, which is involved in regulation of downstream pathways. DARPP is phosphorylated at different sites. In mice, if DARPP is knocked out or its phosphrylation sites are mutated, then the psychotic effects of amphetamines, PCP, and LSD are reduced.

Lileks puts Dateline and Salam Pax in their place

In case you haven't noticed, I do support the War on Terror and President Bush. You might call me a conservative, but I don't consider myself a Republican. For me, most elections are a choice between the lesser of two evils. I think there are many people in the center like me that feel no affinity for either party. But the events of 9-11 have caused many centrists and right- or left-of-centrists to support those who we feel will be most aggressive in defending the U.S. from further attacks no matter what their party affiliation. And we find ourselves increasingly impatient with the popular media that distracts us from the importance of the War on Terror with either stories about pedophilic pop stars or whining about quagmire this, quagmire that. James Lileks, a writer for the Star-Tribune in Minneapolis, pretty much sums up my feelings towards the popular media in his latest column on his blog, The Daily Bleat. Check it out.

Vegan Marshmellows Roasting Over an Open Fire

Sure, some days I get down about graduate school and I think, "Does anyone really care about fruit fly vision? What is the point of my thesis project? Does it have any practical application (actually, yes it does, but I'll discuss that later)? Will it make the world a better place?" Um, scratch that last one. But then I read about an enviroterrorist trying to invent a vegan marshmellow and I feel much better about myself.

President Bush is Da Man!

Read President Bush's speech at Whitehall Palace. Here's an excerpt that I really like:

"It's been said that those who live near a police station find it hard to believe in the triumph of violence, in the same way free peoples might be tempted to take for granted the orderly societies we have come to know. Europe's peaceful unity is one of the great achievements of the last half-century. And because European countries now resolve differences through negotiation and consensus, there's sometimes an assumption that the entire world functions in the same way. But let us never forget how Europe's unity was achieved -- by allied armies of liberation and NATO armies of defense. And let us never forget, beyond Europe's borders, in a world where oppression and violence are very real, liberation is still a moral goal, and freedom and security still need defenders."

Read the whole thing.
President Bush Discusses Iraq Policy at Whitehall Palace in London


I used to be a member of amnesty internation in high school, back when I was a wide-eyed, idealistic tree-hugger. I thought that my letters to the despotic regimes of the world would help free their political prisoners and black-list me so that I could never visit those countries again for fear of being thrown in a dark, rat-infested dungeon for 20 years. Ha!

Anyway, I grew out of that difficult phase and now I'm wondering how anyone could take AI seriously. I mean they'd rather rip on Bush and America then address the thousands enslaved in Sudan. Go figure.

So anyway, this is my first attempt at fisking (which should be a new Olympic sport because it really gets the blood going).



First of all, Dubya? Not even President Dubya? Where are your manners Missy?

By Kate Allen Uk Director Amnesty International

THOUSANDS of people will take to the streets in Britain next week to voice their anger, frustration and political opposition to President George W Bush's policies.

Oooh, thousands. How many millions of people aren't protesting, but are gainfully employed? Ever had a job besides running some lame-o "human rights" group and flipping burgers?

Some will criticise these protestors, writing off their views as knee-jerk anti-Americanism. But the critics should think before condemning them.

Yes, I'll think. Ok, done. I still think you guys are morons with too much time on your hands and you should get proper jobs.

Why? Because after almost three years of President Bush's "war on terror" many would argue that the world is now a more dangerous and divided place than it was immediately after 9/11.

The many being who, exactly? The leftist, anti-American groups like ANSWER, and NOT IN OUR NAME? I definitely think the world's more dangerous-- dangerous for cockroaches like Osama and Hussein.

Countries don't protect freedom by attacking hard-won civil liberties, locking up thousands of people without charge or trial, and rushing through ever-more draconian laws.

You don't win the hearts and minds of the doubters and the disaffected by riding roughshod over human rights.

Thousands of people you say? This wouldn't be the same people from Al Qaida and the Taliban, groups that have massacred thousands of civilians all over the world in terrorist attacks? Screw 'em I say! They were caught red-handed in Iraq, they are unlawful combatants, and by the Geneva Convention, we can lock them up and throw away the key. Okay, okay, we can't throw away the key, but we can try them in military tribunals.

But you DO provide terrorists and extremists with the kind of propaganda they could only have dreamt of a few years ago.

All right, so in addition to "kill the Great Satan because they are controlled by the evil Zionists pigs and monkeys" they've got "kill the Great Satan because they violated the constitutional rights of our brethren in Gitmo as well as section blah-blah-blah of the Geneva Convention." Right...I think the former argument plays a lot better in the mosques and madrassas. But that's just me.

Take Guantanamo Bay. What is the impact of the image of the orange boiler-suited detainees crouching in submission behind Camp Delta's chain-link fences?
Most people in this country seem to be revolted that nearly 700 people are held without charge or trial and without access to lawyers or family for almost two years. They question our own government's weakness in failing to properly stand up for the rights of the nine British men imprisoned in Guantanamo Bay.

Most people eh? According to what poll? Well, my informal poll of friends and family couldn't care less what happens to these terrorists.

RIGHTLY, they wonder whether our government would have been more robust had these men been held by a country like Iran or Syria or almost any other country besides the US.

Hate to break it to you, lady, but there's a big difference between the governments of Iran, Syria, and the U.S. We have this little thing called the Constitution. So yes, likely Blair would have been more robust if these guys were held in some hell-hole in Iran or Syria. But how likely is that? We don't get along with those countries so why would we house unlawful combatants there? Sheesh here we go again with accusing the U.S. of human rights violations while ignoring the horrible abuses by other countries.

But, take the understandable outrage in this country and apply it to a Middle-Eastern country. When the manacled men from Guantanamo Bay flash up on Al-Jazeera television, for example, we can easily guess that outrage reaches new levels.

I'm sure Al-Jaqueera viewers are regularly outraged, what with all the anti-American propaganda streaming out.

No Americans are being held at Camp Delta. Only non-US citizens.

John Walker Lindh, the so-called "American Taliban", was given a defence attorney and brought before an independent civilian court. Camp Delta's "enemy combatants", on the other hand, have to endure indefinite detention without charge or trial and no access to legal counsel or any court.

Perhaps this is because Lindh is an AMERICAN CITIZEN and he was not ruled an UNLAWFUL COMBATANT. He does have rights afforded to him as a citizen. Non-citizens, however, being held as unlawful combatants on a base that is not technically property of the U.S., do not have the same rights.

Hanging over them is the possibility of unfair trials, military tribunals with restricted rights of defence, no independent appeals and the threat of the death penalty.

Oh brother. I'm supposed to feel sorry for the poor wittle tewowists? Please.

It stinks. And that's why Amnesty International plans to make its point - on the streets of London dressed in orange boiler suits.

Here's to seeing you guys wearing the same outfits when you're tossed in the slammer for disorderly conduct.

The journey from the Twin Towers to Guantanamo Bay has been a disastrous one - from an international atrocity to an international disgrace. It is a massive own goal in the war on terror and its sinister consequences are likely to haunt the world for years.

I'll tell you what haunts me, missy. Seeing those towers fall. There's not a day that goes by that I don't think about our fight against terrorism. You seem not to understand what is at stake--our whole way of life, liberty and the pursuit of happiness. The terrorists we are fighting want to destroy all of it and remake the world in their own image. One global nation of Islam under Allah is what they want.

Instead, you and the other lefty groups are distracting the world from that real issue and demand that we wring our hands over a few hundred thugs locked up in Gitmo. The lives of millions, perhaps billions are at stake and you're crying because the Gitmo gang has to wear an unflattering color?!

But it is not just Guantanamo Bay that is so worrying. Since September 11 the USA has used its over-arching "war on terror" as an alibi to create a parallel justice system to detain, interrogate, charge or try suspects under the "laws of war".

In mainland USA people have already been held under military procedures as "enemy combatants'. For example, Jose Padilla - the so-called Dirty Bomber - has been held for more than a year in solitary confinement at a naval prison in South Carolina. He is imprisoned without charge, trial or access to his lawyer or family.

Padilla, a former Chicago gang member, was arrested after flying back into the US from the Middle East where he had, according to officials, been plotting to use a bomb packed with radioactive waste on the US.

This is a virtually unprecedented suspension of the fundamental rights of a US citizen in US custody - not to mention a violation of international law.

Uh, no it's not. Actually, U.S. courts have ruled that the President has the power to detain American citizens as unlawful combatants without a trial under circumstances. Also this authority it not limited to only wartime conditions. This precedent was set during the Civil War in The Prize Cases, 67 U.S. 635 (1862) where it was decided a formal declaration of war was not necessary. My guess as to why Padilla was ruled an unlawful combatant while Lindh was not is because the former was a member of Al Qaeda, while Lindh was a low-level foot soldier in the Taliban. Sheesh, read some case law, will ya.

In other countries people in the hands of US forces are seemingly classified as "enemy combatants" simply if Donald Rumsfeld's Defense `Department says they are. In Iraq as many as 10,000 people are being held, most without any legal process.

Beyond the high media visibility of Guantanamo Bay there also appears to be a shadowy network of "war on terror" detention sites.

At the US air base at Bagram in Afghanistan, for example, former inmates have spoken of a regime of forced stripping, hooding, blindfolding with blacked-out goggles, 24-hour lighting, sleep deprivation and prolonged restraint in painful positions.

As with Guantanamo Bay, Amnesty International is not allowed into Bagram and not even the Red Cross has had access to all prisoners there.

Meanwhile, there are rumours of other prisons - on island military bases or in embassy buildings. These are unconfirmed, but the US already admits to holding people at "undisclosed locations".

Frighteningly, what we are seeing is the almost day-by-day erosion of the USA's commitment to human rights. Where once the world might have looked to America for inspiration, Bush's America is now actively undermining the international system for human rights protection.

Waahhh!!! And where is the famed international system for human rights with regards to the suffering of North Koreans, Iranians, Zimbabwians, Sudanese Christians etc. These are the real people that are suffering and yet AI spends all its energy on Bush=Hitler mantras.

On other issues the trend is the same - America ripping up the rulebook. The US is now by far the most active opponent of the new International Criminal Court, a court that the US should be celebrating as a historic attempt to deter and punish genocide, war crimes and crimes against humanity.

INSTEAD it has embarked on a campaign of bullying weaker countries into agreeing exemptions for US personnel.

Could the reason that the U.S. is not a fan of the ICC is that any two-bit lawyer with an axe to grind could try to arrest American leaders and military members whenever they felt like it? I don't think so. The U.S. will not give up its sovereignty to the likes of Belgium and France. Many Americans view the U.N. and the I.C.C. with skepticism because of the rampant corruption and cronyism. Until the U.N. is reformed, forget about any cooperation from the U.S. with regards to the I.C.C.

Next week the slogans of the protestors will be mixed - anything from anti-war messages on Iraq, opposition to "Star Wars" defence projects, environmental objections to America's gas-guzzling economy and protests at its trade policies.


But one thing unites these voices. A belief that the United States has strayed way off course and forgotten its own traditions of supporting human rights and fundamental liberties.

Excuse us if we no longer want to be a doormat for those that would take advantage of the rights and priviledges we enjoy as U.S. citizens. Excuse Pres. Bush for not leaving the question of U.S. security to a bunch of dithering, corrupt U.N. bureaucrats.

Crucially, Bush protests will also test our own government's commitment to freedom of speech and legitimate dissent in Britain.

Yes, the U.K.'s commitment to freedom has been tested and under the leadership of Blair, it commitment to freedom is stronger than ever.

This month a court controversially ruled that police use of terrorism powers to arrest peaceful protestors at an arms fair in Docklands, East London was reasonable. Why are ordinary people with a point of view on the arms industry considered a threat to the nation?

I don't know anything about these "peaceful" protestors, but my guess is that they got arrested because they were doing things that were naughty and illegal.

Mr Bush's three-day trip to Britain is a high-level visit with all of the pomp and ceremony of any such occasion.

However, the right to have your say is a proud British tradition and the government should see to it that policing during President Bush's visit is done with a light touch.

Yes, please feel free to make fools of yourselves in front of the world. Just don't assault others and vandalize property.

There should be no "exclusion zones" and Mr Bush should not be protected from protests.

I definitely want my president protected from those "peace" protesters. And since when is harassment a right?

Four years ago protestors during the visit of Chinese President Jiang Zemin had flags and banners ripped from their hands. Then the Metropolitan Police behaved in a way more reminiscent of the Chinese secret police than the friendly British bobby.

If they were acting like the Chinese secret police then the protestors would have been shot in the back of the head and their organs sold to the highest bidder. Give me a break.

This time let's hear it for peaceful, good-humoured free expression. Taking to the streets to protest during George Bush's visit will be pro-American and pro-human rights.

Exercising your legitimate right to protest is a core American - and British - value. It's what makes me proud to protest.

Here, here. Please don't hurt anybody and just try to control your Hate-Bush glee. It's very unbecoming. Almost as unbecoming as a pink tank (via LGF):

Update: There's a great commentary on the ICC from Right Wing News.

Only Sadomasochists Go to Graduate School

What was I thinking when I decided to get a Ph.D. in Biophysics? Apparently, I had nothing better to do with my spare time. The really frustrating thing is that my graduating depends on whether or not I can stick a microscopic piece of glass onto the surface of a fly eye cell and measure current going through the cell. This involves sitting in a cramped, dark room all day long and much cursing (or pseudocursing in my case). First you rip the head off of unsuspecting young flies, then you rip the eyes off, and rip the cells apart. Yes, lots of violent ripping and/or tearing. Fun.

Of course my two favorite questions about grad school are: so when are you graduating (argh!) and so how is your work relevant to anything. ? Look, I'm getting out this year with or without my mentor's approval, and it's not relevant to anything, ok?! It might be relevant if you are a fruit fly geek but other than that, it definitely won't cure cancer or AIDS or depression or get me a drug patent and make me rich. Sorry.

But some days I do enjoy school. Usually these are the days that my experiments actually work and get cool data. Like this:

So what the heck is that thing? It's a cluster of fruit fly photoreceptors (eye cells) magnified 400 times. Each cell has two main sections: the cell body, where the nucleus is located and the rhabdomere where all the visual proteins are located. The bright stripes are rhabdomeres from two photoreceptor cells. They're fluorescent because I inserted a gene encoding a fluorescent protein into the fly's genome. The fluorescent protein is calcium sensitive, so it's brighter when there's calcium around. In this picture, the cell cluster is sitting in a high calcium solution and when light excites the cell, calcium rushes into the cell. Thus, the calcium increase inside the cell causes the fluorescent protein to glow. But that's enough nerdy stuff for now.

If you're really interested in how fruit flies (and other insects ) see then try this link to an article written by yours truly at wikipedia. And if you are interested, then you might be a geek.

Is the U.N. getting a clue?

And one last tidbit on the War on Terror: U.N.: Al Qaeda Trying to Use WMDs

Yah think?

Now, what if anything is the U.N. going to do about this? Maybe they'll decide to go out for a "working" lunch at some swanky NYC restaurant, double park their limos, and block traffic for 3 hours again.

Update: Apparently, the U.N. is acting like its usual self (via Instapundit).

File this under "I told you so!" - Intelligence Report Links Saddam, Usama

I was going to whine and moan about the hellhole known as graduate school, but this topic is much more important. It seems that the Weekly Standard is reporting the contents of a DOD memo to the Senate Intelligence Committee that inextricably links Al Qaida and Saddam's regime.
FOXNews.com - Top Stories - Intelligence Report Links Saddam, Usama

A copy of the full article from the The Weekly Standard is here via LGF.

Now, this comes as little surprise to many Americans. Although there were a few reports earlier regarding the Iraqi/Al Qaida links such as the discovery of the Salman Pak training site, the names of specific individuals and terrorist acts committed against Americans by these individuals was not widely known. But it just takes a little common sense to figure out that Al Qaida and Saddam's gang were sides of the same coin. Many of the international terrorists groups are connected in some fashion. Who cheered after 9/11? Why, all the Islamic terrorist groups (including the Palestinians) did! Their goals are the same--to eliminate the Great Satan (the U.S.), the Lil' Satan (Israel), and establish a world-wide caliphate under sharia law.

I think the majority of Americans made this connection themselves as shown by this poll, where 70% of Americans polled believed that Saddam was involved in the 9-11 attacks. Now perhaps Saddam himself didn't directly help plan 9-11, but according to the article he and his people certainly did all they could to help out Al Qaida. And there is additional evidence that Mohammed Atta met not once, but three times with the former (tee-hee) chief of Iraqi intelligence.

Remember all those journalists and celebrities calling the American public stupid and uninformed because of that poll? Well, it's time for them to open wide and eat some crow. Fair-minded individuals may still think that ousting Saddam was the wrong strategy, but they can no longer say that Saddam has nothing to do with Al Qaida.

So enough of the "Bush is a nazi/liar/idiot/failure" and "no blood for oil" crap. As soon as the American public is aware of this report, the anti-war left (and right) will be finished.

I'm technologically challenged part deux

I'm getting a crash course in html and the site's starting to shape up. I'll have a ranty mc-rant up soon.
