This male water flea of Bosmina genus debuted in a UB lab. Male water fleas that scientists have never seen have made their debut in a University at Buffalo laboratory, providing biologists with their first glimpse of these elusive organisms.

Biologists are making a concerted effort to catalogue all the molecular components of living things, from the smallest molecules and ions to the genetic code.

T-ray sensing and imaging technology, which can spot cracks in space shuttle foam, see biological agents through a sealed envelope and detect tumors without harmful radiation, was the focus of a recent symposium at the national meeting of the American Chemical Society.

More lives could be saved in the United States by spending less money on making medical treatments better and more on getting existing treatments to the patients who need them, according to a study published by a Virginia Commonwealth University family medicine and public health physician.

There was a low rate of life-threatening adverse reactions to the smallpox vaccine administered to potential first responders to a bioterrorism incident, possibly attributable to rigorous vaccine safety screening and educational programs, according to a study in the December 7 issue of JAMA.

In findings illustrating the difficulty of developing an AIDS vaccine, UCLA AIDS Institute researchers report the immune systems in two HIV-positive identical twins responded to the infection in different ways.

NASA researchers, using data from the agency's AURA satellite, determined the seasonal ozone hole that developed over Antarctica this year is smaller than in previous years.

A laboratory study has uncovered new details about how estrogen can activate natural pathways that kill certain breast cancer cells or tumors. The results raise the possibility that estrogen therapy may overcome resistance to certain breast cancer hormonal therapies. The study appears in the December 7 issue of the Journal of the National Cancer Institute.

Scientists have devised a strategy to treat tumors by selectively targeting and killing the malignant cells. A new preclinical study, published in the open access journal PLoS Medicine, has applied the approach to combat glioblastoma multiforme (GBM). This is the most aggressive form of brain tumour, growing very quickly before symptoms are experienced and killing most patients within a year of diagnosis.
