A new study has uncovered the genetic wiring diagram underlying the infectiousness of Candida albicans, a fungus that causes thrush in babies, vaginal infections in women, and life-threatening infections in chemotherapy and AIDS patients. The study, led by Dr. Gerald R. Fink, Director of the Whitehead Institute for Biomedical Research, reveals that one key to CandidaÃs infectiousness lies in its ability to switch from a rounded form to filamentous forms. When the wiring diagram underlying this switch is inactivated, Candida infections are no longer deadly in mice.

Proving that even minor planets can survive cosmic fender-benders, astronomers using the Hubble Space Telescope have discovered a large crater - with an estimated diameter at 285 miles and about 8 miles deep - on the asteroid Vesta. The crater is roughly the diameter of Ohio, and may be the source of many meteorites that reach the earth.
Consumers can expect "unimagined innovation" as electric utility deregulation brings competitive suppliers to local distribution companies, Cornell University economist Richard E.

When it comes to reproductive fitness, it seems that mother knows best -- at least when mother is the common fruit fly. But two scientists have found that the act of mating is far more harmful to females than the act of egg laying. The study may give clues to how females help control their own reproductive fitness, according to a University of Georgia geneticist who is co-author of the research, to be published in the journal Evolution.
New evidence by scientists from the University of Georgia indicates that victims of a common tropical disease may be receiving inadequate treatment because of a major misunderstanding of how the illness progresses.
