Global warming strikes again. A University of Illinois researcher reports that a red-winged black bird population in Ontario, Canada has decreased by 50 percent since 1972.   view more (2006-11-14)

NASA and NOAA Announce Ozone Hole is a Double Record Breaker
NASA and National Oceanic and Atmospheric Administration (NOAA) scientists report this year's ozone hole in the polar region of the Southern Hemisphere has broken records for area and depth.   view more (2006-10-23)

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)

Mapping the Milky Way
A new map of the centre of our own galaxy, The Milky Way, is the biggest, most detailed, and most sensitive yet made. The map shows giant streamers and huge clouds of interstellar gas where stars are being born 26,000 light years from Earth - shedding new light on the exotic structures in this... view more (2000-12-19)

Gastrointestinal bleeding can be fatal - something which is not known to many alcoholics.   view more (2008-02-19)

Uncovering Sex-Change Secrets Of The Black Sea Bass
In a former cowshed on the edge of the University of New Hampshire campus, David Berlinsky, assistant professor of zoology, peers into a big blue plastic tub.   view more (2006-04-12)

Study shows hibernating bears conserve more muscle strength than humans on bed rest do
A fascinating new study from the May/June 2007 issue of Physiological and Biochemical Zoology quantifiably measures the loss of strength and endurance in black bears during long periods of hibernation.   view more (2007-04-25)

UCR biologists unravel the genetic secrets of black widow spider silk
Biologists at the University of California, Riverside have identified the genes, and determined the DNA sequences, for two key proteins in the "dragline silk" of the black widow spider - an advance that may lead to a variety of new materials for industrial, medical and military uses.   view more (2007-06-13)

Physicists describe a new mechanism for metallic magnetism
Predicting the magnetic behavior of metallic compounds is a surprisingly difficult problem for theoretical physicists.   view more (2005-08-26)

Paint used by Dutch masters turns into rat poison
The painters Willem Kalf, Jan Davidsz. de Heem and Balthasar van der Ast are particularly famed for their bright yellow orpiment ("royal yellow"). The researchers have shown that light causes a chemical reaction in this yellow which separates the sulphur and the arsenic. The sulphur is released... view more (1999-05-17)

Study: urban black bears 'live fast, die young'
Black bears that live around urban areas weigh more, get pregnant at a younger age, and are more likely to die violent deaths, according to a study by the Wildlife Conservation Society.   view more (2008-10-01)

Sociologists explore 'emotional labor' of black professionals in the workplace
Black professionals make extra efforts in the workplace to fulfill what they believe are the expectations of their white colleagues, according to research to be presented today at the annual meeting of the American Sociological Association (ASA).   view more (2008-08-04)

Computer models show major climate shift as a result of closing ozone hole
A new study led by Columbia University researchers has found that the closing of the ozone hole, which is projected to occur sometime in the second half of the 21st century, may significantly affect climate change in the Southern Hemisphere, and therefore, the global climate.   view more (2008-06-13)

3-D ultrasound scanner provides in-depth view of the brain
Biomedical engineers at Duke's Pratt School of Engineering have adapted a three-dimensional ultrasound scanner that might guide minimally invasive brain surgeries and provide better detection of a brain tumor's location.   view more (2007-06-21)

Soviet plans implemented by Nature 90,000 years ago
One of the more controversial environmental issues, which emerged in the final years of the Soviet era, was the plan to dam and reverse the flow of north-flowing rivers in order to irrigate the dry southern steppes. This scheme was roundly criticised by scientists and environmentalists at the time... view more (2002-01-22)

Blowing away ethnic stereotyping in tests
It is often thought that Asian cultures value accuracy over speed of performance and Black groups are less concerned with accuracy than White groups. Contrary to popular belief research shows these stereotypes do not exist in psychometric testing.   view more (2005-01-07)

Surprises from the Sun's South Pole
Although very close to the minimum of its 11-year sunspot cycle, the Sun showed that it is still capable of producing a series of remarkably energetic outbursts-ESA-NASA Ulysses mission revealed.   view more (2007-02-20)

Uncharged organic molecule can bind negatively charged ions
Indiana University Bloomington chemists have designed an organic molecule that binds negatively charged ions, a feat they hope will lead to the development of a whole new molecular toolbox for biologists, chemists and medical researchers who want to remove chlorine, fluorine and other negatively... view more (2008-02-27)

Plenty of nothing: A hole new quantum spin
Electronic devices are always shrinking in size but it's hard to imagine anything beating what researchers at the University of New South Wales have created: a tiny wire that doesn't even use electrons to carry a current.   view more (2006-07-26)

Race may be risk factor for insulin resistance
Black women — even if their weight is normal — may be at increased risk for insulin resistance, a condition associated with diabetes, high blood pressure, and heart vessel disease, according to new research by Wake Forest University School of Medicine.   view more (2006-06-27)

Study finds more PSA screening awareness needed among high-risk groups
In one of the first examinations of PSA screening in younger men, a study published by researchers at Duke Medicine's Prostate Center finds that one-fifth of men under age 50 reported undergoing a prostate specific antigen (PSA) test to detect prostate cancer in the previous year, yet only one in... view more (2008-08-11)

Magnetic misfits: South seeking bacteria in the Northern Hemisphere
Magnetotactic bacteria contain chains of magnetic iron minerals that allow them to orient in the earth's magnetic field much like living compass needles.   view more (2006-01-23)

The dawn of deep ocean mining
We're on the brink of the era of deep ocean mining, says a global pioneer in the study of sea floor mineral deposits.   view more (2006-02-21)

Supernova birth seen for first time
Astronomers have seen the aftermath of spectacular stellar explosions known as supernovae before, but until now no one has witnessed a star dying in real time.   view more (2008-05-22)

XMM-Newton 'spare-time' provides impressive sky survey
For the past four years, while ESA's XMM-Newton X-ray observatory has been slewing between different targets ready for the next observation, it has kept its cameras open and used this spare time to quietly look at the heavens.   view more (2006-05-04)
