Stellar explosion displays massive carbon footprint
While humans are still struggling to get rid of unwanted carbon it appears that the heavens are really rather good at it. view more (2009-06-01)
Hubble finds mysterious disk of blue stars around a black hole
Astronomers using the NASA/ESA Hubble Space Telescope have identified the source of a mysterious blue light surrounding a supermassive black hole in our neighbouring Andromeda Galaxy (M31). view more (2005-09-21)
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)
Physics World Digest: June 2002 edition
PET targets small animals Finding new drugs for deadly diseases like cancer or Alzheimer`s is no easy task. Suitable drugs first have to be discovered and then tested to ensure that they work properly and without side effects. One way of speeding up the process is to use positron emission tomography (PET). It provides three-dimensional images of... view more... (2002-06-07)
Astronomers find first ever gamma ray clock
Astronomers using the H.E.S.S. telescopes have discovered the first ever modulated signal from space in Very High Energy Gamma Rays - the most energetic such signal ever observed. view more (2006-11-28)
Ecological significance of tool-use in the woodpecker finch Cactospiza pallida
The Woodpecker finch, one of 14 Darwin`s finches of the Galapagos Islands, uses twigs or cactus spines to pry insects and spiders out of tree-holes. The advantage of using tools may seem evident, but empirical evidence is scarce. In a paper soon to appear in Ecology Letters, Tebbich and colleagues present the first study on the ecological... view more... (2002-09-09)
Scientists at Low Temperature Laboratory planning to model a black hole
Academy Professor Matti Krusius and Antti Finne, M.Sc. (Eng.), were invited to a recent science breakfast, hosted by the Academy of Finland, to talk about their ongoing work to produce a first-ever laboratory simulation of a black hole. A black hole is created as a result of the most extreme concentration of matter. Scientists have been arguing... view more... (2003-04-16)
Evidence for ultra-energetic particles in jet from black hole
An international team of astronomers led by researchers at Yale has obtained key infrared observations that reveal the nature of quasar particle jets that originate just outside super-massive black holes at the center of galaxies and radiate across the spectrum from radio to X-ray wavelengths. view more (2006-06-21)
Astronomers detect matter torn apart by black hole
Astronomers have used two different telescopes simultaneously to study the violent flares from the supermassive black hole in the centre of the Milky Way. They have detected outbursts from this region, known as Sagittarius A*, which reveal material being stretched out as it orbits in the intense gravity close to the central black hole. view more (2008-11-19)
Hubble spies shells of sparkling stars around quasar
New images taken with NASA's Hubble Space Telescope - part of a research project led by UC Riverside's Gabriela Canalizo - have revealed the wild side of an elliptical galaxy, nearly two billion light-years away, that previously had been considered mild-mannered. view more (2007-10-26)
Pushing black-led arts into the spotlight
Propelling black performers from the sidelines into the mainstream is the mission of Push, a black-led, multidisciplinary arts organisation based in London. With a Fellowship of £74,820 from NESTA (the National Endowment for Science, Technology and the Arts) - which backs UK innovation - Push will build on their considerable successes in... view more...

Milky Way's Giant Black Hole Awoke from Slumber 300 Years Ago
Using NASA, Japanese, and European X-ray satellites, a team of Japanese astronomers has discovered that our galaxy's central black hole let loose a powerful flare three centuries ago. view more (2008-04-16)
Astronomers shed surprising light on our galaxy's black hole
In the most comprehensive study of Sagittarius A (Sgr A), the enigmatic supermassive black hole in the center of the Milky Way Galaxy, astronomers - using nine ground and space-based telescopes including the Hubble Space Telescope and the XMM-Newton X-ray Observatory - have discovered that Sgr A* produces rapid flares close to the... view more...

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)
Black women have urinary incontinence less than half as often as white women
The good news for black women: They have less than half the chance of developing urinary incontinence as do white women, according to a new study from the University of Michigan Health System. view more (2008-04-23)
New vista of Milky Way center unveiled
A dramatic new vista of the center of the Milky Way galaxy from NASA's Chandra X-ray Observatory exposes new levels of the complexity and intrigue in the Galactic center. view more (2009-09-23)
Black Americans Are At Greater Risk for Colon Polyps
Black Americans have a higher occurrence of colon polyps, according to a new study. This is a significant finding considering the incidence of colon cancer among black men has increased and remained unchanged among black women during the last 20 years.

Chemopreventive agents in black raspberries identified
A study published in Cancer Prevention Research, a journal of the American Association for Cancer Research, identifies components of black raspberries with chemopreventive potential. view more (2009-01-08)
Global warming predictions are overestimated, suggests study on black carbon
A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions. view more (2008-11-20)
Redressing the ethnic imbalance in the classroom
Nearly 13 percent of schoolchildren in England are from black and ethnic minority backgrounds, yet 95% of those employed to teach them are white. The TC21 project, managed by Sudha Raghavan in the school of education, is trying to recruit more people from ethnic minorities onto teacher training courses across the region, to try to redress this... view more...
