Dancing bacteria? Engineers explore microbial choreography

December 7, 2005

Birds fly together in flocks. Fish swim together in schools. Everyone has seen the beautiful, seemingly choreographed motions these collections of organisms can exhibit. But surely bacteria, which have no eyes or brain, cannot behave in such a coordinated way. In fact, they do, and researchers are beginning to learn how.

A fatty acid found in milk may help control inflammatory diseases

October 18, 2005

One of the isomers of conjugated linoleic acid, a group of fatty acids found in milk, is a natural regulator of the COX-2 protein, which plays a significant role in inflammatory disease such as arthritis and cancer, according to a study published by UW–Madison researchers.

New program in neuroscience and public policy offered

September 13, 2005

Modern neuroscience is advancing understanding of the brain and behavior at a pace that few could have imagined even five years ago. The resulting knowledge is transforming our understanding of brain function in health and disease, with profound implications for society. Recognizing this, two UW–Madison faculty now have created a new dual-degree graduate program in Neuroscience and Public Policy to train students how to apply this knowledge to problems in public policy.

The World’s Tiniest Badger?

September 6, 2005

NanoBucky, created in the research lab of UW–Madison chemistry professor Robert Hamers, is composed of tiny carbon nanofiber “hairs,”each just 75 nanometers in diamete

A single gene controls a key difference between maize and its wild ancestor

August 31, 2005

One of the greatest agricultural and evolutionary puzzles is the origin of maize - and part of the answer may lie in a plot of corn on the western edge of Madison, where a hybrid crop gives new life to ancient genetic material. A UW–Madison genetics team has demonstrated that a single gene, called tga1, controls kernel casing in maize — evidence that modest alterations in single genes can cause dramatic changes in the way traits are expressed.
