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)
ASU researchers use NASA satellites to improve pollution modeling
Detecting pollution, like catching criminals, requires evidence and witnesses; but on the scale of countries, continents and oceans, having enough detectors is easier said than done. view more (2007-12-18)
Gone With the Wind? Over A Hundred Scientists Take To The Skies To Track Global Air Pollution
This morning a team of forty scientists from seven UK universities will travel to the Azores to join hundreds more in the largest international atmospheric field campaign of its type ever attempted. The exciting mission will track and investigate a mass of polluted air as it leaves the United States and travels across the Atlantic to the UK and... view more... (2004-07-08)
Precise measurement of phenomenon advances solar cell understanding
Researchers at Washington University in St. Louis have shed light on a basic process that could improve future solar cells. view more (2008-11-19)
NASA study: Alaskan fires affected Houston air quality in 2004
An innovative new NASA-funded study based on a combination of satellite data, computer models and weather balloon readings finds that smoke from Alaskan and Canadian forest fires as much as doubled ground-level ozone thousands of miles away in Houston during a two-day period in July 2004. view more (2006-09-22)
Pitt Researchers Zero In on Ozone With Fluorescent Solution That Detects Harmful Molecule in the Air and Body
Researchers at the University of Pittsburgh have developed a fluorescent substance that glows bright green when exposed to even minute amounts of ozone in the air and in biological samples such as human lung cells. view more (2009-06-23)
NASA's Chandra finds black holes are 'green'
Black holes are the most fuel efficient engines in the Universe, according to a new study using NASA's Chandra X-ray Observatory. view more (2006-04-25)
A new method to weigh giant black holes
How do you weigh the biggest black holes in the universe? One answer now comes from a new and independent technique that UC Irvine scientists and other astronomers have developed using data from NASA's Chandra X-ray Observatory. view more (2008-07-17)
Link between ozone air pollution and premature death confirmed
Short-term exposure to current levels of ozone in many areas is likely to contribute to premature deaths, says a new National Research Council report, which adds that the evidence is strong enough that the US Environmental Protection Agency should include ozone-related mortality in health-benefit analyses related to future ozone standards. view more (2008-04-23)
Quasar light variability linked to black hole mass
Quasars are some of the most luminous and distant objects in the universe - and appear to have something in common with ordinary light bulbs. view more (2007-01-09)
Key molecule discovered in Venus's atmosphere
Venus Express has detected the molecule hydroxyl on another planet for the first time. This detection gives scientists an important new tool to unlock the workings of Venus's dense atmosphere. view more (2008-05-16)
Oh, my aching back: Give me a shot of ozone
A minimally invasive interventional radiology treatment-that safely and effectively uses oxygen/ozone to relieve the pain of herniated disks-will become standard in the United States in the next few years, predict researchers at the Society of Interventional Radiology's 34th Annual Scientific Meeting. view more (2009-03-09)
By ice floe to the North Pole
At the end of August, an unusual expedition under Russian leadership will leave for the Arctic Ocean. One of the participants is Jürgen Graeser of the Alfred Wegener Institute for Polar and Marine Research, one of the research centres of the Helmholtz Association. view more (2007-07-23)
Low levels of contamination also influence mortality rate
Navarre doctor Rosa Mar'a Al'¡s Brun has shown, in her PhD thesis defended at the Public University of Navarre, that, despite contamination rates in Pamplona being very low, these still have an influence on death rates. view more (2004-08-20)
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)
Catalytic converter gets the pollution out of diesel engines
In the near future the usual summer ozone peaks exceeding the allowed threshold may be a thing of the past: the Paul Scherrer Institute (PSI) in Switzerland has developed a new type of catalytic conversion system, which filters nearly all nitrogen oxides out of diesel exhaust gases using a refined control technology. This eliminates the main cause... view more... (2004-09-08)
Massive Black Hole Smashes Record
Using two NASA satellites, astronomers have discovered the heftiest known black hole to orbit a star. The new black hole, with a mass 24 to 33 times that of our Sun, is more massive than scientists expected for a black hole that formed from a dying star. view more (2007-10-31)
TAU Scientists Help Discover the Most Massive Stellar Black Hole Ever Found
An international team, including astronomers from Tel Aviv University, has uncovered the most massive stellar black hole found to date in a binary system. view more (2007-11-09)
Dancing around the Black Hole
ISAAC Finds "Cool" Young Stellar Systems at the Centres of Active Galaxies Supermassive Black Holes are present at the centres of many galaxies, some weighing hundreds of millions times more than the Sun. These extremely dense objects cannot be observed directly, but violently moving gas clouds and stars in their strong gravitational fields are... view more... (2001-08-14)
New clues to ozone depletion
Laerge quantities of ozone-depleting chemicals have been discovered in the Antarctic atmosphere by researchers from the University of Leeds, the University of East Anglia, and the British Antarctic Survey. view more (2007-07-27)
