May 30, 2010

Those promising little cells that can differentiate into almost any tissue continue to make news – but they also continue to generate controversy.

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 […]

Depressed? Believe in a Caring God

February 28, 2010

“Belief in a Caring God Improves Response to Medical Treatment for Depression, Study Finds.” That’s what Science Daily said.

Barefoot Is Better

January 27, 2010

Who do we wear shoes? It seems obvious; we expect that they help us avoid injuries and provide comfort. Maybe we should think of the injuries we are getting by wearing them. The image of the barefoot person is usually of someone poor, deprived, lower-class, hick, unclean, redneck or something else unattractive. Shoes […]
