Blood Clotting Fibers May Lead to Better Networks
April 22, 2010
We all know that blood clotting has kept us alive many times.  We would never have survived childhood scrapes and cuts had it not been for a cascade of responses in blood that builds a network of fibers quickly upon which a scab of tissue stops the flow of blood and begins repairs.  That first […]

Fruit Flies: From Darwin to Design
March 13, 2010
The fruit fly Drosophila melanogaster is an icon of evolution.  Since the 1930s these poor little bugs have been mutated endlessly and watched for signs of Darwinian change.  So far, though, only useless mutants, unable to survive in the wild, have been produced.  Recently, scientists seem more enamored with their design.  Two recent articles had […]
