Findings may lead to more effective regulations for protecting public health
Using data from one of the most comprehensive U.S. air pollution studies ever conducted, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have identified specific volatile organic compounds (VOCs) as key sources of excess ozone smog in industrial areas of Houston, Texas — which appear to be different from traditional sources of ozone pollution in typical urban areas around the co
Ph.D. candidate Lital Alfonta wins Kaye Award
Lital Alfonta, a Ph.D. candidate in the Faculty of Science at the Hebrew University of Jerusalem, has developed a fast, inexpensive test to determine if an AIDS patient has developed resistance to the medication he is taking. Ms. Alfonta was selected to receive the prestigious Kaye Innovation Award for her work, which could vastly improve treatment of AIDS patients.
Ms. Alfonta, who developed the test under the guidance of Prof.
Brown scientists have described a previously unknown but critical blood-clotting role for Arp2/3, a complex of seven proteins found in animal and plant cells.
Reporting in the June 15 issue of Blood, the scientists show that Arp2/3 complex is a cellular machine that drives a human blood platelet to change shape into a larger, more flattened form and begin the process of clotting. The link between what happens at the surface of a platelet and the mechanism of shape change within it has mystif
A report published today by the European Commission establishes for the first time the situation of women scientists in 30 European countries . The report is presented at a seminar opening today in Madrid and organised with the Spanish Presidency of the European Union on “Women and Science: promoting women in the scientific sector”.
The report, prepared by a group of national representatives known as the `Helsinki Group on Women and Science`, compiles national statistical profiles which ar
Heart patches and functioning kidney units cloned in cows
Advanced Cell Technology, Inc. (ACT) reported today that nuclear transplantation can be used to generate functional immune-compatible tissues. The research, which will appear in the July issue (cover story) of Nature Biotechnology, by ACT and its collaborators, provides the first experimental evidence that it may be possible to use cloning to generate medically important tissues and eliminate tissue rejection. Heart
New product approved to prevent bleeding deaths
A razor nick during a much-too-close-shave ten years ago may result in hundreds of thousands of lives saved in the future. Scientist Frank Hursey was working with absorptive materials back in the late 80’s when he cut himself shaving. He picked up a volcanic mineral he’d been studying and decided to try it on his bleeding wound. The product worked so well as a coagulant that Hursey set to work doing further testing.
After three
