driven to the water's edge

I have long believed that one of the major advantages of being a geek is that it is much easier to come into contact with your heroes. As an example, this Monday, I drove off to Mote Marine to listen to science writer Carl Zimmer speak on recent developments in cetacean evolution. The talk itself was a quick layperson's review of thirty or forty years of work on the evolution of whales. Much of it focused on the developments of the last ten years, and it was well-expressed for a non-technical audience.

Of course, that wasn't really the point.

The point was getting to meet an author whose works I've been reading for a great many years, and who is good at getting his own point across. In this, the talk was another expression of his writing: to take sometimes complex and arcane science, and to boil it down to its most interesting and exciting elements. It has been fun to follow his keystrokes as he moves from subject to subject in science, first exploring evolution at the water's edge, moving on to parasites, then exploring the social history behind the discovery of the brain, and most recently, our relationship with the ubiquitous E. coli. His blog and his science columns and commentary for the New York Times and Wired Magazine are even more diverse summaries describing the state of the art in a number of different fields.

Science needs more folks like this who are capable of expressing such discoveries in a manner that is at once both entertaining and informative. The entertainment is important, for while the thrill of discovery or the intuitive leap that results in new understanding is the real joy of science, much of the everyday work is like any job: dull, repetitive - full of endless monotony as you grind towards results and conclusions that you hope will be revolutionary and new... but will probably do nothing more than continue to support existing data. Science can also be intimidating, with the primary literature full of needlessly specific technical jargon, sometimes requiring much reading through diverse and obscure papers and journals to understand a single subject.

His writing keeps science fresh, cutting through all of the hard work to the conclusions at the end of a long day (or decade) that are what really inspire scientists to keep moving. This kind of writing may go on to inspire another generation of scientists, and to develop an appreciation for and an understanding of science outside of the technical community in the same way that folks appreciate the work of a farmer, or a mechanic, a dot-com tycoon, or even a lowly politician.

That, and as a lark, he now keeps track of all of the really cool science tattoos. How can you get any more awesome than that?

seeing the world differently?

If the eyes are the windows to the soul, then a new pair of glasses must be a bit like remodeling the front of the house with nice new victorian picture-windows. I can see clearly again and live without glare while driving.

Rah!

saturday morning cartoons

One of the advantages to my new home is that the sun peeks in through my window as it rises, and very little will keep its persistant determination from lifting the lids of my eyes for very long. As a result, I was up at what might normally be considered an unnaturally early hour of the morning for myself - especially on the weekend. Lacking anything better to do with my time, or failing to want to do anything more than get some breakfast and go back to sleep, I watched my version of Saturday morning cartoons on Google Video.

I put a bagel in the toaster, spread some peanut butter on it, and sat down to watch Craig Mello give a talk at Google corporate headquarters on his Nobel-winning research on RNAi as part of their continuing seminar series on emerging technologies. The tech talks are interesting because they give you a look into what the almighty Google is thinking about buying and turning into their next cash-cow. Dr. Mello's talk is interesting because he is a good speaker and does an excellent job of translating highly technical jargon into plain english that the layperson might understand and appreciate without feeling condescended to. That, and he is talking about RNA interference, one of the single most interesting and important topics to hop along through molecular biology in the last ten years. To say that I am excited by its potential application in various subfields of biology and chemistry would be something of an understatement.

If you have an hour and ten minutes to kill, I highly recommend that you check it out...

know your roots

"My dear, descended from the apes! Let us hope it is not true, but if it is, let us pray it will not become generally known."
- attributed to the wife of the Bishop of Worcester, in reaction to the infamous debate between TH Huxley and the Bishop Wilberforce

While I do not subscribe to the "great man" theory of history, there is no question that Charles Darwin happened to be the right scientist in the right place at the right time. Spurred on to publication by Alfred Russel Wallace, the "father of biogeography", his observations from years of collected research led him to conclusions that shook the foundations of biology and the society built atop that platform. His work brought forth a mechanism by which the whole of diversity might be explained within the context of geological history. When linked to the evidence of heredity first explored by Mendel, and then confirmed at the molecular level by Watson and Crick (and Franklin!), it provided the unifying synthesis of modern biology.

As I am dedicating my life to following the science that he helped to establish, it is with some interest that I note that my own life has from time to time, accidentally fallen into Darwin's footsteps. I have touched the same armoured glyptodontids that he helped to unearth in Southern Argentina at the Museo de la Plata. I have stood in the home he kept, and looked through the study to the desk at which he wrote much of his work. Lately, I have seen the villainous vinchuca that was to bring him low in his later years with Chagas disease in a new light, and finally, I have stood atop his grave at Westminster Abbey in London.

Everyone has their heroes.

Happy Darwin Day, everybody.

grad school rocks! grad school is going to make my brain explode!

So...

Thursday night last week was one of the better days I have had in a long time. Not only was I looking at a three-day weekend due to the observance of Veteran's Day, but the seminar speaker for the afternoon was Dr. Jim Marden - a guy I think of as famous for his work on the evolution of flight in early insects. He has done a lot more work on a lot more integrative biology since then - pushing the science at the level of the gene into its effects on behavior and population structure. One of the projects he is exploring looks at the frequencies of certain genes in a metapopulation of butterflies. These genes are responsible for the butterflies' ability to convert sugar to energy and stay aloft for long periods of time, and inadvertently represent the butterflies' ability to migrate from one area to another. Butterflies who express one form of this gene tend to be very good at staying in their natal patch and reproducing there. Butterflies who express another form of this gene tend to disperse and migrate out onto new patches.

raining and pouring

Okay... as of today, it appears that I have a new major advisor for graduate studies in entomology, and a new project focus for my education. I will now complete a lifelong goal by defending America from an alien invasion. Admittedly, this will be an invasion of small biting arthropods known as thrips, but they're strange enough to be from beyond this world.

They are tiny parasitic insects of about a milimeter in length whose wings can only be described as feather dusters. They are incredibly prolific, and once a colony is established, it can be extremely difficult to eradicate. Worse still, they are promiscuous parasites, readily leaping from a preferred host to an alternate host when environmental conditions demand. Most important of all, they can also act as vector to several commercially important plant viruses, and to top matters off, they will bite human beings when they run out of plants.

It appears that Florida stands poised on the brink of invasion by a creature that could only be described as an enemy to all I hold dear - the Chilithrips, Scirtothrips dorsalis. It will be my duty to develop a management strategy to control and identify their advance across the nation. Millions stand to perish if I fail.

I am actually looking forward to the challenge. I mean, it isn't mosquitoes, but it still will be ecological control of a potentially harmful species, and it presents all sorts of interesting opportunities to explore the evolution and adaptation of an invasive species: resistance, founder's effect, structured competition, host-shifting and sympatric speciation. As in all such things, only time will tell.

boots boots boots

Will someone kindly remind me to go out and purchase a new set of hiking boots at some point during this weekend? I've quite worn the rubber soles of my old pair of Wolverines down to their leather lining, and the steel toe-gaurds are starting to shine through. It is wonderful to note that the wear patterns of a shoe can reveal much about their user's health and habits. Mine reveal that I have high arches, and that I like to sprint on my toes, rolling across the ball of my foot instead of my heel. They also imply that I usually fence with my right foot forward, dragging my left leg on deep lunges - and that I walk with my toes pointing slightly outwards: a sure sign of lateral chondromalacia...

science and policy

The abuse and misuse of science in the media by policymakers in order to manipulate the electorate has been a problem nearly as long as there have been elected officials. These distortions inevitably begin almost as soon as the government grants funding to public institutions of science, and the refrain of "don't trouble me with the facts!" has long echoed in the halls of power. In America, the distortion or suppression of science in order to legitimize or justify one's particular ideology has had a long and flavored history. One need look no farther than John Wesley Powell and the United States Geological Survey's scientifically sound settlement plan for the West just after the Civil War.

Walking fish is harder than walking dogs, but it still beats walking sticks...

From the NYT Science section:

Fossil Called Missing Link From Sea to Land Animals
By JOHN NOBLE WILFORD
Scientists found evidence of limbs in the making in the 375-million-year-old fish's forward fins.


The funny thing is that in an interview I listened to on NPR yesterday, one of the scientists mentioned that he hated hearing finds such as this described as "the missing link", because it is merely one missing piece in a long chain of missing pieces, and furthermore, it does not actually represent an ancestral state within a linear progression towards tetrapody and eventually humanity. It is unquestionably a branch that shares ancestors with the line that would lead to amphibians, but its large size, developed neck, and the migration of eyeballs to the top of its head imply that the process towards terrestrialization had already been underway for some evolutionary time.

The other funny bits come later in the article when discussing the relevance of 'transitional forms' to Creation-"Science". There is an argument lifted reducto ad absurdum about how finding this fossil only proves the need to find intermediaries between this 'half-way point' and the next... or to point out that even if amphibians are descended from fish, you still can't demonstrate that fish are descendants of invertebrates, but I suppose that they haven't heard of Pikia...

Last but not least, the idea of giant killer salamanders always brings a smile to my face.
Then I think about the vicious and voracious tiger salamanders I had as a kid, and suddenly I am maybe not smiling so much anymore...

Google takes over another planet

Price


We followed the interstate down the path opened by the Wasatch fault, stopping briefly in Price, Utah to visit two locales of international renoun.

Our first visit was to the emergency room that once cared for myself and three other travelers, seven long years ago. It was during the return leg of our March 1998 Spring Break road trip to the Western Coast that a careless jackrabbit leapt out into our headlights, and into destiny. It left the four of us suspended upside-down in a ditch: Roy Huggins blind in one eye and bleeding, Elizabeth Tweig concussed with a series of scratches on her head that mysteriously parallel my front teeth, myself concussed with shattered sinuses, and Sarah Olivieri... with a broken fingernail. The Castleview Hospital's emergency room is still right where it used to be, and still ready to take in all visitors at all hours, no matter how far away, or how serious the car wreck.

The second locale was of no less significance, but of greater personal interest. Price, Utah also happens to be home to one of the best dinosaur collections in the world. The College of Eastern Utah maintains a Prehistoric Museum sampling the paleontology and archaeology of the area. This tiny museum in this tiny town is home to some of the richest fossil beds in the world, and as a result, the local natural history museum is better stocked than the collections of many larger cities.

It is unusual returning to this place. The last time I was here, I was still somewhat concussed and using an old pair of glasses that my mother had thought to bring to replace the pair I had lost on the roadside. Between the persistent wooziness and a prescription nearly two years out of date, my memories of the time spent there are a little softer around the edges than usual.

The museum does not appear to have changed substantially in the seven years we have been apart, but many things which were once hidden are now visible. The Utahraptor, once trapped within the matrix of rock that held it, was now free to terrorize the coastal plains running along the Western Interior Sea of North America once more. When last I visited, the Utahraptor had just been revealed to the world in a rare example of science following art: until their discovery, the only members of the Dromeosauridae clan known to be that large hailed from the Steven Spielberg cinematic adaptation of the Michael Crichton novel, Jurassic Park.

In another odd twist of fate, and more proof that the world is a smaller place than one might initially suspect, it turns out that Reese Barrick, a paleontologist I had once hoped would be my advisor at NCSU, had also ended up at this spectacular museum as a curator. As we leave, it occurs to me that I too could settle here and be happy.
