Carinne Blank has a method she uses to date ancient life forms that could be helpful for specimens from Mars.A geologist from Washington University in St. Louis is developing new techniques to render a more coherent story of how primitive life arose and diverged on Earth – with implications for Mars.

Male Bahamas mosquitofish (left) chasing a female (right).A biologist at Washington University in St. Louis has shown that for some fish species, females prefer males with larger sexual organs, and actually choose them for mating. That does not exclude males with an average-sized sex organ, called a gonopodium. These fish out-compete the larger-endowed males in a predator-laden environment because they have a faster burst speed than the males with larger genitalia, thus avoiding predators and staying in the mating game.

St. Louis is the site for the world’s premier software engineering annual conference from May 15-21 at the Adam’s Mark Hotel. The 27th International Conference on Software Engineering (ICSE 2005) features the latest research in software engineering, displays, exhibits, seminars, co-located conferences, and social gatherings that bring the world’s elite together in an unprecedented hub of activity in information technology (IT) in the Gateway City. Gruia-Catalin Roman, Ph.D., Harold B. and Adelaide G. Welge Professor of Computer Science and chair of the Department of Computer Science and Engineering at Washington University in St. Louis, is the general chair for ICSE 2005 and was highly influential in bringing the conference to St. Louis,

Chemistry Professor Karen L. Wooley is principal investigator of a program that has received funding of $12.5 million for five years.

They were able to match the genetic sequence of the bacterium Mycobacterium avium to the same bacterium found in the lungs of ill lifeguards.

The award was given for their outstanding academic performances and diversity of courses taken at the University.

Washington University in St. Louis has been chosen as a Program of Excellence in Nanotechnology (PEN) by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. Karen Wooley, Ph.D., Washington University professor of chemistry in Arts & Sciences, is principal investigator of the Program, which NHLBI is funding at $12.5 million for five years.

They used a unique instrument at WUSTL called the “NanoSIMS” — a type of secondary ion mass spectrometer — to determine these findings.

A WUSTL researcher has identified a bacterium as the pathogen living on bubbles in hot water environments.A team of researchers, led by an environmental engineer at Washington University in St. Louis, has applied a molecular approach to identify the biological particles in aerosol responsible for making employees of a Colorado hospital therapeutic pool ill. They found: when the bubble bursts, the bacteria disperse, and lifeguards get pneumonia-like symptoms.

Combinatorial chemistry provides researchers a vast library from which to choose.A researcher studying drug design for nerve damage therapies has gotten her answer to questions by following some old advice: she used the library. It’s not the kind of library her mother or teacher suggested, but a combinatorial chemistry library of many different protein sequences that some day might help her and her colleagues develop a successful timed drug delivery system.
