As engineering grad student at UCDavis, I am interested in the common ground between biology and machinery. Incidentally, my column's title refers to the way bacteria navigate-- first they "run"... Read More »

The universe is a lazy place.  If a system of particles can find a way exist in a lower-energy state, you’d better believe that the system will seek it out.  A group of researchers from Amherst and Berkeley are capitalizing on this universal tendency toward calculated sloth by using self-assembly to create denser storage media. 
A team of biomechanical and paleontological researchers at University of Manchester are exploring a question that teenaged dinosaur girls have wondered for years: how thin should a dinosaur model be?

Karl Bates and his team built their supermodels using a framework reconstructed from museum-installed skeletons, using an infrared laser scanning technique called LiDAR.
Thanks to advances in satellite technology, college students are giving government intelligence a run for its money.  A student geography project from UCLA made waves in the Harvard International review for using principles of wildlife diversity to narrow bin Laden’s likely location to a few promising structures in Pakistan.  

Bin Laden has everything in common with a member of a species trying to escape extinction. This allowed the UCLA students used theories of wildlife dispersion to predict his whereabouts. 
The Archaeopteryx is experiencing a phoenix-like reascent to fossil celebrity status.  The disovery of this clearly birdlike dinosaur in 1861 lent ethos to Darwin’s brand new Theory of Evolution.  In December, the Thermopolis, WY archaeopteryx fossil was escorted to the Stanford Synchrotron Radiation Lightsource laboratory for synchrotron X-ray analysis.  According to researcher Uwe Bergmann, "What you normally can't see are the chemical elements from the original organism that might still be present in the fossil. Using X-ray fluorescence imaging, we can bring these elements to light, getting a better look at the fossil and learning more about the original animal.”
"When people live where the weather is colder and they are more covered with clothing, they depend on their diet for their vitamin D," reports Raymond Hobbs, MD.  Dr. Hobbs’ study in the January/February issue of Endocrine Practice reveals that Detroit-area Arab-American women who wear the hijab, modest dress with headscarf, receive approximately half of the vitamin D of their western-dressed Arab-American neighbors.  
Helen Fisher at TED, 2008

I recently spoke to biological anthropologist Dr. Helen Fisher about her groundbreaking work on the chemical basis of our personality and its influence on who we fall in love with.  As it turns out, science can shed a lot of light on a topic previously dominated by doubt, horoscopes, and what our mama told us.

 “So have you read the book?” asked Fisher.  “What ‘type’ are you?” 

 “Explorer/Negotiator.  Are you sizing me up according to my ‘type’ now?” I teased.
