Sophisticated telescope camera debuts with peek at nest of black holes
Less than two months after they inaugurated the world's largest telescope, University of Florida astronomers have used one of the world's most advanced telescopic instruments to gather images of the heavens. view more (2009-09-16)
'Cosmic ghost' discovered by volunteer astronomer
When Yale astrophysicist Kevin Schawinski and his colleagues at Oxford University enlisted public support in cataloguing galaxies, they never envisioned the strange object Hanny van Arkel found in archived images of the night sky. view more (2008-08-06)
Two cosmic bursts upset tidy association between long gamma-ray bursts and supernovae
Two brilliant flashes of light from nearby galaxies are puzzling astronomers and could indicate that gamma-ray bursts, which signal the birth of a black hole, are more diverse than once thought. view more (2006-12-21)
Does racial stereotyping still occur in psychiatry?
Ten years ago, psychiatrists rated black male patients as potentially more violent than white patients. A study in this week's BMJ asks does such racial stereotyping still occur? A postal questionnaire, concerning the first presentation of a young man at casualty, was sent to 1000 British psychiatrists. It included a photograph, brief history, and... view more... (2001-10-17)
Collaboration shines possible light on objects 'weirder than black holes'
Researchers from Duke University and the University of Cambridge think there is a way to determine whether some black holes are not actually black. view more (2007-09-25)
Ethnicity important factor in rates of gonorrhoea and chlamydia infections
Rates of gonorrhoea and chlamydia are about three times as high in black Caribbeans as they are in black Africans, shows a study in Sexually Transmitted Infections. Cases of gonorrhoea and chlamydia, recorded at 11 sexual health clinics in Lambeth, Southwark, and Lewisham Health Authority for the years 1994 and 1995, were studied. Ethnic group was... view more... (2001-02-02)
Science with Integral -- 5 years on
With eyes that peer into the most energetic phenomena in the universe, ESA's Integral has been setting records, discovering the unexpected and helping understanding the unknown over its first five years. view more (2007-10-18)
Caltech astronomers describe the bar scene at the beginning of the universe
Bars abound in spiral galaxies today, but this was not always the case. A group of 16 astronomers, led by Kartik Sheth of NASA's Spitzer Science Center at the California Institute of Technology, has found that bars tripled in number over the past seven billion years, indicating that spiral galaxies evolve in shape. view more (2008-07-30)
Closer To The Monster
Trailblazing VLT Interferometer Studies of the Central Region in Active Galaxy NGC 1068 [1] Fulfilling an old dream of astronomers, observations with the Very Large Telescope Interferometer (VLTI) at the ESO Paranal Observatory (Chile) have now made it possible to obtain a clear picture of the immediate surroundings of the black hole at the centre... view more...

LHC switch-on fears are completely unfounded
A new report published on Friday, 5 September, provides the most comprehensive evidence available to confirm that the Large Hadron Collider (LHC)'s switch-on, due on Wednesday next week, poses no threat to mankind. Nature's own cosmic rays regularly produce more powerful particle collisions than those planned within the LHC, which will enable... view more... (2008-09-08)
Mystery spiral arms explained?
Using a trio of space observatories, astronomers may have cracked a 45-year old mystery surrounding two ghostly spiral arms in the galaxy M106 (NGC 4258). view more (2007-04-11)
Black pudding may interfere with cancer screening test
Eating black pudding may interfere with a screening test for colorectal cancer, claim researchers in this week’s Christmas issue of the BMJ. view more (2002-12-18)
Largest, brightest supernova ever seen may be long-sought pair-instability supernova
An exploding star first observed last September is the largest and most luminous supernova ever seen, according to University of California, Berkeley, astronomers, and may be the first example of a type of massive exploding star rare today but probably common in the very early universe. view more (2007-05-08)
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)
100 Photographs in the Blink of an Eye
Scientists from the Universities of Sheffield and Southampton in collaboration with the UK Astronomy Technology Centre at the Royal Observatory, Edinburgh have just opened a new window on the Universe by commissioning ULTRACAM - an ultra-fast camera which can take up to 1000 pictures a second in three different colours simultaneously. The camera,... view more... (2002-07-24)
UCSB professor's paper on safety of large hadron collider to be published in Physical Review D
Particle colliders creating black holes that could devour the Earth. Sounds like a great Hollywood script. view more (2008-06-30)
Oldest stars may shed light on dark matter, researchers report in Science
The universe's earliest stars may hold clues to the nature of dark matter, the mysterious stuff that makes up most of the universe's matter but doesn't interact with light, cosmologists report. view more (2007-09-14)
Discovery of most recent supernova in our galaxy
The most recent supernova in our Galaxy has been discovered by tracking the rapid expansion of its remains. This result, using NASA's Chandra X-ray Observatory and NRAO's Very Large Array (VLA), has implications for understanding how often supernovas explode in the Milky Way galaxy. view more (2008-05-15)
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 predict how to detect a fourth dimension of space
Scientists at Duke and Rutgers universities have developed a mathematical framework they say will enable astronomers to test a new five-dimensional theory of gravity that competes with Einstein's General Theory of Relativity. view more (2006-05-26)
