Rising surface ozone reduces plant growth and adds to global warming
Scientists from three leading UK research institutes have today released new findings that could have major implications for food production and global warming in the 21st century. view more (2007-07-26)
2007 ozone hole 'smaller than usual'
The ozone hole over Antarctica has shrunk 30 percent as compared to last year's record size. According to measurements made by ESA's Envisat satellite, this year's ozone loss peaked at 27.7 million tonnes, compared to the 2006 record ozone loss of 40 million tonnes. view more (2007-10-04)
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)
Inside the Ozone Layer
A new atmospheric model is able to quantify man-made versus naturally occurring damage to the stratosphere with an eye toward repairing the diminishing ozone layer that is located within the stratosphere. view more (2006-02-24)
Study finds two supermassive black holes spiraling toward collision
A pair of supermassive black holes in the distant universe are intertwined and spiraling toward a merger that will create a single super-supermassive black hole capable of swallowing billions of stars. view more (2006-04-06)
Biggest 'small' black hole discovered
Discovery of the largest example of a "small" black hole - one formed from the collapse of a single massive star at the end of its lifetime - has led scientists to revaluate of how black holes come into being, according to a report in Nature. view more (2007-10-22)
Green Plants Share Bacterial Toxin
A toxin that can make bacterial infections turn deadly is also found in higher plants, researchers at UC Davis, the Marine Biology Laboratory at Woods Hole, Mass. view more (2006-11-07)
Monster black holes grow after galactic mergers
An analysis of the Hubble Space Telescope's deepest view of the universe offers compelling evidence that monster black holes in the centers of galaxies were not born big but grew over time through repeated galactic mergers. view more (2006-01-11)
Mayo Clinic researchers find hole in heart does not make stroke inevitable
Mayo Clinic researchers have found that - contrary to current thinking by some in the medical community - a patent foramen ovale (PFO), a small hole between the two upper chambers of the heart, does not predestine an individual to a stroke later in life. view more (2005-12-12)
San Andreas Fault Observatory at Depth reveals new insights into the 'earthquake machine'
The San Andreas Fault Observatory at Depth (SAFOD)-the first underground observatory to provide physical samples and real-time seismological data from deep inside an active fault zone-is yielding surprising new clues about the origin of earthquakes. view more (2005-12-06)
Flies in a spider's web: Galaxy caught in the making
In nature spiders earn our respect by constructing fascinating, well-organised webs in all shapes and sizes. But the beauty masks a cruel, fatal trap. Analogously, the NASA/ESA Hubble Space Telescope has found a large galaxy 10.6 billion light-years away from Earth (at a redshift of 2.2) that is stuffing itself with smaller galaxies caught like... view more...

Scientists find black hole's 'point of no return'
Scientists have found new evidence that black holes are performing the disappearing acts for which they are known. view more (2006-01-11)
Astronomers use laser to take clearest images of the center of the Milky Way
UCLA astronomers and colleagues have taken the first clear picture of the center of our Milky Way galaxy, including the area surrounding the supermassive black hole, using a new laser virtual star at the W.M. Keck observatory in Hawaii. view more (2005-12-21)
MAGIC discovers variable very high energy gamma-ray emission from a microquasar
In a recent issue of Science Magazine, the Major Atmospheric Gamma-ray ImagingCherenkov (MAGIC) Telescope has reported the discovery of variable very high energy (VHE) gamma-ray emission from a microquasar. view more (2006-05-19)
Chandra discovers light echo from the Milky Way's Black Hole
Like cold case investigators, astronomers have used NASA's Chandra X-ray Observatory to uncover evidence of a powerful outburst from the giant black hole at the Milky Way's center. view more (2007-01-11)
NASA Study Finds Clock Ticking Slower On Ozone Hole Recovery
The Antarctic ozone hole's recovery is running late. According to a new NASA study, the full return of the protective ozone over the South Pole will take nearly 20 years longer than scientists previously expected. view more (2006-06-30)
Cosmic battle creates Milky-Way sized tunnel
A team of astronomers is announcing today that they have discovered a giant Milky Way-sized tunnel filled with high energy particles in a distant galaxy cluster. view more (2006-01-12)
Astronomers discover new kind of black-hole explosion
Scientists have discovered what appears to be a new kind of cosmic explosion - a "hybrid gamma-ray burst" - which will be the subject of four articles to be published in the journal Nature on 21 December 2006. view more (2006-12-21)

Assessing the Amazon River's sensitivity to deforestation
Understanding how the Amazon River varies in time, what causes those variations, and how sensitive it will be to ongoing, and accelerating, deforestation is a focus of study for scientists at the Woods Hole Research Center. view more (2005-06-21)
