Washington, Nov 20 : NASA astronauts on space shuttle Endeavour’s STS-126 mission will install an instrument known as “ENose” on the International Space Station
(ISS) that can help protect crew members’ health and safety by “smelling” dangerous chemicals in the air.
The experimental ENose will monitor the space station’s environment for harmful chemicals such as ammonia, mercury, methanol and formaldehyde.
The ENose, which will run continuously and autonomously, is the first instrument on the ISS that will detect and quantify chemical leaks or spills as they happen.
Washington, Nov. 20 : Though they have not launched direct attacks on Barack Obama''s leading choice to lead the Justice Department, Eric Holder Junior, the Republican National Committee (RNC) is not hesitating to highlight the latter’s role in controversial 2001 pardons.
Republican congressional aides said no information had emerged that would disqualify Holder, a former D. C. Superior Court judge and U. S. attorney in the District, from serving as the nation''s top law enforcement officer.
FDA advisory committee yesterday called on the U. S. Food and Drug Administration and other U. S. health agencies to study the long-term effects of prescribing powerful antipsychotic drugs to children. The committee said antipsychotics are increasingly prescribed to children, often for unapproved uses, such as treating attention deficit disorders or ADHD.
Washington, Nov 20 : Scientists have announced the discovery of a previously unidentified nearby source of high-energy cosmic rays, which was made with a NASA-funded balloon-borne instrument high over Antarctica.
The team that made the discovery comprised of researchers from the Advanced Thin Ionization Calorimeter (ATIC) collaboration, led by scientists at Louisiana State University, Baton Rouge, US.
Washington, Nov 20: Scientists searching for physical evidence for the elusive dark matter might find it in the form of high-energy electrons captured over Antarctica.
According to a report in National Geographic News, the authors of the new study flew a balloon-borne particle collector called the Advanced Thin Ionization Calorimeter
(ATIC) over Antarctica.
Circular winds at that latitude allow the balloon to stay aloft for up to 30 days at a time, capturing electrons and measuring their charges, energies, and trajectories.
The ATIC found inflated numbers of high-energy electrons that match the signal expected from the destruction of dark matter.
Washington, Nov. 20: Some women’s groups are hoping that U. S. President-elect Barack Obama will ensure gender balance at the Pentagon.
Army Gen. Ann Dunwoody broke through it last week, becoming the military’s first female four-star general. But groups representing women in national security roles want the obstacle to shatter completely.
“Gen. Dunwoody’s promotion is the major advance we’ve been waiting for 10 years,” Politico quoted Lory Manning, director of the Women’s Research and Education Institute’s Women in the Military Project, as saying.
