Setting stars reveal planetary secrets
Watching the stars set from the surface of the Earth may be a romantic pastime but when a spacecraft does it from orbit, it can reveal hidden details about a planet's atmosphere.   view more (2007-11-06)

Alternative states in the ocean
Ecologists expect natural communities to vary. Occasionally, however, such variation can be severely abrupt and lead to formation of alternative and potentially persistent states. In the July issue of Ecology Letters, Paine and Trimble describe a dramatic assemblage shift on a rocky intertidal... view more (2004-05-13)

Microbes use sunscreens too
Microbes can withstand extreme levels of atmospheric ultraviolet light (UV) by producing their own sunscreens. Unlike humans, some bugs may even be able to survive without any help from the ozone layer scientists heard today (Thursday 19 September) at the Society for General Microbiology autumn... view more (2002-08-28)

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)

A hidden twist in the black hole information paradox
Professor Sam Braunstein, of the University of York's Department of Computer Science, and Dr Arun Pati, of the Institute of Physics, Sainik School, Bhubaneswar, India, have established that quantum information cannot be 'hidden' in conventional ways, or in Braunstein's words, "quantum... view more (2007-02-28)

Stratospheric ozone chemistry plays an important role for atmospheric airflow patterns
Interactions between the stratospheric ozone chemistry and atmospheric air flow lead to significant changes of airflow patterns from the ground up to the stratosphere.   view more (2008-03-10)

Ozone can affect heavier people more
A new study provides the first evidence that people with higher body mass index (BMI) may have a greater response to ozone than leaner people.   view more (2007-11-27)

Flares illuminate the secret life of a quiescent black hole
Astronomers probing the intimate details of apparently quiescent stellar black holes have discovered that in reality they are dynamic, lively places, subject to flares that briefly illuminate the whole of the gas disc around the black hole. Their observations are helping to build up a picture of... view more (2002-04-04)

How much can you work?
At the same time as many urban economies are developing into 24-hour societies, it is becoming increasingly popular amongst shift workers to compress their working hours. This is done by working longer shifts and/or restricting free time in-between shifts. The advantage is longer consecutive... view more (2005-05-20)

Food could be made safer by surface decontamination with steam
Trials have been carried out using steam below, at, or above atmospheric pressure. As the pressure of the steam is increased, higher decontamination temperatures can be achieved. Comparative studies are also assessing the use of treatments with hot air, water immersion, infrared irradiation,... view more (1999-11-29)

UI researchers discover star orbiting a 'medium-sized' black hole
University of Iowa researchers have found a star orbiting a "medium-sized" black hole - about 1,000 times more massive than the sun - in the nearby starburst galaxy M82, a development that may help explain how medium-sized black holes form and evolve.   view more (2006-01-06)

No matter their size black holes 'feed' in the same way
Research by UK astronomers, published today in Nature (7th December 2006) reveals that the processes at work in black holes of all sizes are the same and that supermassive black holes are simply scaled up versions of small Galactic black holes.   view more (2006-12-07)

Ozone levels may raise risk of underweight births
Babies born to women exposed to high ozone levels during pregnancy are at heightened risk for being significantly underweight.   view more (2005-11-17)

The Last Cry Of Matter
'Black holes' are truly black. When an object gets within a certain distance from a black hole, it will get swallowed forever with no chance to escape. That includes light, which means that black holes do not shine. How do astronomers detect black holes if they are unable to see them? Well, to be... view more (2003-11-27)

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... 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)

Anxiety before surgery complicates recovery in children
Children who are anxious before surgery experience a more painful, slow, and complicated postoperative recovery, according to a Yale School of Medicine study published this month in Pediatrics.   view more (2006-08-23)

£250,000 for clinical trials of functional strength training for the lower limb
The University of Manchester and St George's Hospital Medical School, in collaboration with Manchester Metropolitan University, have been awarded £250,000 by the PPP Foundation to carry out clinical pilot studies into functional strength training of lower limbs in patients who have suffered a... view more (2003-01-22)

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)

Early Promise For Stroke Patients Given
A preliminary study published in this week’s issue of THE LANCET suggests that the neurotransmitter precursor levodopa used in combination with physiotherapy could improve motor recovery for patients after stroke. Hemiplegia (paralysis to one side of the body) causes functional disability... view more (2001-09-05)

Lack of sleep activates body's defence mechanisms
A lack of sleep is considered a threat situation, which activates the body's defence mechanisms. This is the same type of response that protects the body against viruses and bacteria as well as in stress situations.   view more (2005-03-16)

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)

Substance abuse practitioners ask 'what is recovery?'
Abstinence from alcohol and drugs is just the starting point in defining "recovery" for people with substance abuse disorders, according to a paper in the October issue of the Journal of Substance Abuse Treatment (JSAT).   view more (2007-11-01)
