Scientists have reconstructed the formation of two curious features in the northern ice cap of Mars — a chasm larger than the Grand Canyon and a series of spiral troughs — solving a pair of mysteries dating back four decades while finding new evidence of climate change on Mars.
Did you stay up all night to hear your local result during the recent election?
Time-consuming manual vote-counts and ballot boxes could soon be consigned to the history books, thanks to innovative new secure voting technology.
The system is being developed by computer scientists at the Universities of Surrey and Birmingham, with funding from the Engineering and Physical Sciences Research Council (EPSRC), and in collaboration with the University of Luxembourg.
A surprising discovery that hydrogen gas clouds found in abundance in and above our Milky Way Galaxy have preferred locations has given astronomers a key clue about the origin of such clouds, which play an important part in galaxy evolution.
Astronomers studying the Milky Way have discovered a large number of previously-unknown regions where massive stars are being formed. Their discovery provides important new information about the structure of our home Galaxy and promises to yield new clues about the chemical composition of the Galaxy.
GREENBELT, Md. -- A test unit for the "NIRCam" instrument that will fly aboard the James Webb Space Telescope has arrived at NASA's Goddard Space Flight Center in Greenbelt, Md. and has been placed in a clean room for a year's worth of tests.
A team of astronomy researchers at Rochester Institute of Technology, Florida Institute of Technology and University of Sussex in the United Kingdom, find that the supermassive black hole (SMBH) at the center of the most massive local galaxy, M87, is not where it was expected. Their research, conducted using the Hubble Space Telescope, concludes that the supermassive black hole in M87 is displaced from the galaxy center.
DALLAS – May 25, 2010 – As part of a multicenter study, UT Southwestern Medical Center researchers have identified a series of chemical compounds that might serve as starting points for the identification of new classes of anti-malarial drugs.
For over 10 years, NASA's Chandra X-ray Observatory has repeatedly observed the Andromeda Galaxy for a combined total of nearly one million seconds. This unique data set has given astronomers an unprecedented view of the nearest supermassive black hole outside our own Galaxy.Astronomers think that most galaxies - including the Milky Way - contain giant black holes at their cores that are millions of times more massive than the Sun.
OAK BROOK, Ill. – A new rule preventing medical support staff from completing orders for outpatient imaging exams that were likely to be negative resulted in a marked decrease in low-yield exams for patients, according to a study appearing in the June issue of Radiology. Many medical institutions request and schedule outpatient diagnostic imaging exams through use of web-based radiology order entry systems. Some systems offer real-time feedback, called decision support, on the appropriateness of the exams being ordered.
The team will present its data and images during a 5:30-6:30 p.m. poster session on Monday, May 24, at the Miami, Fla., meeting of the American Astronomical Society.
GREENBELT, Md. -- NASA, which pioneered the technology used for the satellite-aided search and rescue capability that has saved more than 27,000 lives worldwide since its inception nearly three decades ago, has developed new technology that will more quickly identify the locations of people in distress and reduce the risk of rescuers.
AUGUSTA, Ga. - A cell small in number but powerful in its ability to switch the immune system on or off is a unique hybrid of two well-known immune cell types, Medical College of Georgia researchers report.
Early on Saturday, May 22, Tropical Storm 02A moved into the Gulf of Aden and was named "Bandu." At that time, Bandu had maximum sustained winds near 45 knots (52 mph) and was 50 miles north-northwest of Cape Guardafui, Somalia. NASA's Aqua satellite recently captured Bandu's fading thunderstorms over inland Somalia.
