E. coli work identifies new keys to regulation of bacterial gene expression

June 16, 2006

The cellular process of transcription, in which the enzyme RNA polymerase constructs chains of RNA from information contained in DNA, depends upon previously underappreciated sections of both the DNA promoter region and RNA polymerase, according to work done with the bacterium E. coli and published today (June 16) in the journal Cell by a team of bacteriologists from the University of Wisconsin–Madison.

New approach allows closer look at smoker lungs

May 30, 2006

Aided by a powerful imaging technique, scientists have discovered they can detect smoking-related lung damage in healthy smokers who otherwise display none of the telltale signs of tobacco use.

Dedication ceremony honors revered freshwater biologist

May 8, 2006

A dedication ceremony at the Center for Limnology (CFL) today (May 8) is honoring the vision and achievements of a late UW–Madison scientist by naming a laboratory after him. The newly named facility - the Arthur Davis Hasler Laboratory for Limnology - has been at the core of education and UW–Madison research in the aquatic sciences for more than four decades.

Scaled-down genome may power up E. coli’s ability in lab, industry

April 27, 2006

By stripping the E. coli genome of vast tracts of its genetic material — hundreds of apparently inconsequential genes — a team of Wisconsin researchers has created a leaner and meaner version of the bacterium that is a workhorse of modern biology and industry.

Scientists discover a master key to microbes’ pathogenic lifestyles

April 27, 2006

A team of scientists from the University of Wisconsin–Madison School of Medicine and Public Health reports the discovery of a master molecular sensor embedded in the spores of the fungi that triggers a transformation from that of a benign lifestyle in the soil to a deadly pathogen.

‘Virtual’ symposium brings nanotech, biotech topics to K-12 science teachers

March 28, 2006

On Monday, May 1, educators from around Wisconsin will join with educators in Indiana and Minnesota to explore the convergence of nanotechnology and biotechnology with a panel of experts drawn from the University of Wisconsin–Madison, the National Science Foundation and Wisconsin's biotechnology community. The New Technologies symposium will originate from the Pyle Center at UW–Madison and will be broadcast live via Internet2 beginning at 8 a.m.

Engineers squeeze secrets from proteins

March 21, 2006

Proteins, one of the basic components of living things, are among the most studied molecules in biochemistry. Understanding how proteins form or "fold" from sequenced strings of amino acids has long been one of the grand challenges of biology.
