New paper describes connections between Circadian and metabolic systems
A paper by University of Notre Dame biologist Giles Duffield and a team of researchers offers new insights into a gene that plays a key role in modulating the body's Circadian system and may also simultaneously modulate its metabolic system. view more (2009-11-13)
U-M discovery about biological clocks overturns long-held theory
University of Michigan mathematicians and their British colleagues say they have identified the signal that the brain sends to the rest of the body to control biological rhythms, a finding that overturns a long-held theory about our internal clock. view more (2009-10-09)
Invading black holes explain cosmic flashes
Black holes are invading stars, providing a radical explanation to bright flashes in the universe that are one of the biggest mysteries in astronomy today. view more (2009-09-21)
Using magnetism to turn drugs on and off
Many medical conditions, such as chronic pain, cancer and diabetes, require medications that cannot be taken orally, but must be dosed intermittently, on an as-needed basis, over a long period of time. view more (2009-09-21)
Radiologists and engineers develop a modified catheter to reduce contrast material injuries
Though rare, IV contrast material administration can sometimes result in patient injury. However researchers have developed a modified catheter that may prevent such events from occurring. view more (2009-09-21)
Penetrating insights: NIST airframe tests help ensure better shielding for flight instruments
Airline travelers are used to being instructed to turn off computers and cell phones during takeoffs and landings as a precaution against interfering with the plane's navigational equipment, but outside sources of high-energy interference can be even more dangerous. view more (2009-08-27)
Pitt research suggests EPA pesticide exposure test too short, overlooks long term effects
The four-day testing period the U.S. Environmental Protection Agency (EPA) commonly uses to determine safe levels of pesticide exposure for humans and animals could fail to account for the toxins' long-term effects, University of Pittsburgh researchers report in the September edition of Environmental Toxicology and Chemistry. view more (2009-08-18)
Typhoon Morakot Cloud Top Extent Doubled In Size in One Day
Satellite imagery over the last two days has shown Typhoon Morakot to be a monster, and over the last two days, NASA satellites have confirmed the typhoon doubled its size! view more (2009-08-07)
Seeing the Cosmos Through
NASA's Spitzer Space Telescope has taken its first shots of the cosmos since warming up and starting its second career. The infrared telescope ran out of coolant on May 15, 2009, more than five-and-half-years after launch, and has since warmed to a still-frosty 30 Kelvin (about minus 406 Fahrenheit). view more (2009-08-06)
Turbulence responsible for black holes' balancing act
We live in a hierarchical Universe where small structures join into larger ones. Earth is a planet in our Solar System, the Solar System resides in the Milky Way Galaxy, and galaxies combine into groups and clusters. view more (2009-07-15)
NASA's Fermi Finds Gamma-ray Galaxy Surprises
Back in June 1991, just before the launch of NASA's Compton Gamma-Ray Observatory, astronomers knew of gamma rays from exactly one galaxy beyond our own. view more (2009-07-15)
Foster care may boost brain activity of institutionalized children
Children raised in institutions are more likely to lag physically, socially, and cognitively, but little is known about what happens to children's brains when they live in institutions. view more (2009-07-15)
Is the sky the limit for wind power?
In the future, will wind power tapped by high-flying kites light up New York? A new study by scientists at the Carnegie Institution and California State University identifies New York as a prime location for exploiting high-altitude winds, which globally contain enough energy to meet world demand 100 times over. view more (2009-06-16)
Scripps Florida scientists devise accelerated method to determine infectious prion strainsScripps Florida scientists devise accelerated method to determine infectious prion strains
Current tests to identify specific strains of infectious prions, which cause a range of transmissible diseases (such as mad cow) in animals and humans, can take anywhere from six months to a year to yield results - a time-lag that may put human populations at risk. view more (2009-05-29)
XMM-Newton takes astronomers to a black hole's edge
Using new data from ESA's XMM-Newton spaceborne observatory, astronomers have probed closer than ever to a supermassive black hole lying deep at the core of a distant active galaxy. view more (2009-05-28)
Children who are depressed, anxious or aggressive in first grade risk being victimized later on
Children entering first grade with signs of depression and anxiety or excessive aggression are at risk of being chronically victimized by their classmates by third grade. view more (2009-05-15)
Faster than the speed of sound: New control system has what it takes to guide experimental aircraft
When a jet is flying faster than the speed of sound, one small mistake can tear it apart. And when the jet is so experimental that it must fly unmanned, only a computer control system can pilot it. Ohio State University engineers have designed control system software that can do just that -- by adapting to changing conditions during a flight. view more (2009-04-30)
Scientist warns over pandemic flu vaccine 6-month time lag
New research published today (Monday April 27) from the University of Leicester and University Hospitals of Leicester NHS Trust warns of a six-month time lag before effective vaccines can be manufactured in the event of a pandemic flu outbreak. view more (2009-04-28)
Scripps research scientists model 3D structures of proteins that control human clock
In an Early Edition issue of The Proceedings of the National Academy of Sciences (PNAS) on April 9, 2009, the researchers report that they have been able to determine the molecular structure of a plant photolyase protein that is surprisingly similar to two cryptochrome proteins that control the "master clock" in humans and other mammals. view more (2009-04-13)
Study Compares Sound from Exploding Volcanoes with Jet Engines
New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. view more (2009-04-09)
