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.

USAF 388th Range SqdGenesis was recovered in the Utah desert with fears that all data were lost.Scientists at Washington University in St. Louis have begun to measure noble gases present in the solar wind delivered to Earth by the Genesis spacecraft, the first sample return mission since the lunar Apollo missions in the late 1960s and early 1970s.

The first detailed studies of two of the largest human chromosomes have revealed enormous gene “deserts” lacking any protein-coding sequences and relics of the merger of two ape chromosomes to form a single human chromosome.

LightmanAlan Lightman, popular novelist and MIT physicist, will deliver the ArtSci Council, Phi Beta Kappa and Sigma Xi Lecture for Washington University’s Assembly Series. His talk, “The Physicist as Novelist,” will be held at 11 a.m. Wednesday, April 13, in Graham Chapel.

What makes a woman a woman?The mysteries of both human sex chromosomes have now been laid bare with the publication of the sequence of the human X chromosome in the journal Nature. Scientists at the Wellcome Trust Sanger Institute in England led the effort to sequence the X, with significant contributions from the Genome Sequencing Center at Washington University.

The Monsanto Fund has awarded Washington University $3.7 million to develop, build and operate two custom mobile classrooms. Washington University will lead a partnership, including the St. Louis Science Center, the Missouri Botanical Garden, the Saint Louis Zoo, and the University of Missouri-St. Louis, to create and provide programming on the vehicles. The program will help young elementary school students develop enthusiasm for learning and doing science, through interactive experiences and exhibits.

Scientists may have found a way to throw a wrench in the transmissions of several speed demons of the parasite world. Researchers at the School of Medicine and Harvard University have identified a protein that could help them develop drugs to stop or slow cell invasion by malaria and other parasites known as apicomplexans.

The University and the National Consortium for Specialized Secondary Schools of Mathematics, Science and Technology (NCSSSMST) are co-sponsoring a professional conference March 10-12 on the Hilltop Campus. The exploration-themed conference will encourage attendees to “Map Your Course With Math, Science and Technology.”

Michael R. Brent and Tamara L. Doering examine data from the *C. neoformans* microarray.A team of collaborators, including two researchers from Washington University in St. Louis, has sequenced the genomes of two strains of the fungus Cryptococcus neoformans (C. neoformans), one which is virulent, the other harmless. This work provides researchers with clues on how the fungus does its dirty work and a host of genes to study for a better understanding of fungal pathogens in general. Estimates are that about 15 percent of people with HIV will suffer at least one life-threatening infection of C. neoformans. In Africa, that could be as much as 40 percent of HIV sufferers.
