Wisconsin scientists find a way to make human collagen in the lab

February 13, 2006

A team of scientists at UW–Madison reports the discovery of a method for making human collagen in the lab, opening the door to broader medical applications.

From 2D blueprint, material assembles into novel 3D nanostructures

January 27, 2006

An international team of scientists affiliated with the UW–Madison Nanoscale Science and Engineering Center has coaxed a self-assembling material into forming never-before-seen, three-dimensional nanoscale structures, with potential applications ranging from catalysis and chemical separation to semiconductor manufacturing.

Mining for gems in the fungal genome

January 23, 2006

Ever since penicillin, a byproduct of a fungal mold, was discovered in 1929, scientists have scrutinized fungi for other breakthrough drugs. As reported Jan. 20 in the Journal of Chemistry and Biology, a team led by a UW–Madison researcher has developed a new method that may speed the ongoing quest for medically useful compounds in fungi.

Study reveals classic symbiotic relationship between ants, bacteria

January 5, 2006

Ants that tend and harvest gardens of fungus have a secret weapon against the parasites that invade their crops: antibiotic-producing bacteria that the insects harbor on their bodies,UW-Madison researchers report in today's issue of Science.

Advance points way to noninvasive brain cancer treatment

January 1, 2006

With an equal rate of incidence and mortality-the number of those who get the disease and those who die from it-Glioblastoma Multiforme (GBM) is a brain cancer death sentence. Scientists at UW–Madison are working on a new radiotherapy technique for fighting GBM with the element gadolinium — an approach that might lead to less invasive treatments that offer greater quality of life for patients.

Illuminating Alzheimer’s: Research sheds light on creatine’s presence in brain

December 21, 2005

A team of Canadian and American scientists working at the UW–Madison Synchrotron Radiation Center reports the first-ever finding of elevated levels of creatine — the newly discovered agent of Alzheimer's disease - in brain tissue.

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.
