Stick to wild salmon unless heart disease is a risk factor, risk/benefit analysis of farmed and wild fish shows
On the one hand, farmed salmon has more heart-healthy omega-3 fatty acids than wild salmon. On the other hand, it also tends to have much higher levels of chemical contaminants that are known to cause cancer, memory impairment and neurobehavioral changes in children.    view more (2005-12-27)

ESRF helps reveal the origin of the Solar System
Particles returned to Earth last January by the Stardust spacecraft from comet Wild 2 are yielding precious information about the origin of the solar system, thanks to the brilliant X-rays produced at several of the world's synchrotron facilities, including the ESRF.   view more (2006-12-18)

Secrets of a Dark Cloud
SOFI (Son OF ISAAC) is a scaled-down copy of ISAAC, the major VLT instrument that has already produced spectacular observations. SOFI is a unique instrument for the study of extended objects like "Barnard 68 (B68)" because of its very sensitive infrared detector and unrivalled large field-of-view.   view more (1999-07-02)

Gender may play role in recovery from pneumonia after ozone exposure
Does air pollution have a bigger effect on the immune system of females than males? It did among mice exposed to ozone -- a major component in air pollution that is known to negatively affect lung function -- and then infected with pneumonia, as significantly more females died from the infection... view more (2007-06-26)

Hubble's 17th anniversary -- extreme star birth in the Carina Nebula
Hubble's new view of the Carina Nebula shows the process of star birth at a new level of detail.   view more (2007-04-25)

An apple a day may be good for your lungs
Overall, good lung function was associated with high intakes of vitamins C, E, and beta-carotene, citrus fruits, apples, and fruit juices. After adjusting for factors, such as body mass, smoking history, and exercise, only the association with apples remained, suggesting that eating five or more... view more (2000-01-18)

Finally, the 'Planet' in Planetary Nebulae?
Astronomers at the University of Rochester, home to one of the world's largest groups of planetary nebulae specialists, have announced that low-mass stars and possibly even super-Jupiter-sized planets may be responsible for creating some of the most breathtaking objects in the sky.   view more (2008-03-11)

Hubble's sweeping view of the Coma Galaxy Cluster
The NASA/ESA Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of Galaxies, one of the densest known galaxy collections in the Universe.   view more (2008-06-10)

ESA to test the smartest technique for detecting extrasolar planets from the ground
To see a dim planet around a bright star is like looking for a candle flame next to a searchlight. To solve this problem, scientists have developed the concept of nulling interferometry, one of the smartest methods to date in the search for extrasolar planets. The European Space Agency (ESA) and... view more (2002-03-26)

Pioneering University Research Reveals Impact Of Newbury Bypass On The Environment
A three-year study by researchers from the University of Surrey, led by Dr Neil Ward, has revealed that although pollution from the Newbury Bypass in Berkshire has been minimised due to an effective design and higher construction standards, ongoing monitoring and maintenance is crucial in order to... view more (2001-02-09)

Tibet Provides Passage for Chemicals to Reach the Stratosphere
NASA and university researchers have found that thunderstorms over Tibet provide a main pathway for water vapor and chemicals to travel from the lower atmosphere, where human activity directly affects atmospheric composition, into the stratosphere, where the protective ozone layer resides.   view more (2006-05-10)

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... view more (2004-05-04)

Scientists discover 'light echoes' of ancient supernovae
Astronomers have found "light echoes" from three ancient supernovae by detecting their faint, centuries-old light reflected in the clouds of interstellar dust.   view more (2005-12-23)

Hubble finds infant stars in neighbouring galaxy
Hubble astronomers have uncovered, for the first time, a population of infant stars in the Milky Way satellite galaxy, the Small Magellanic Cloud (SMC, visible to the naked eye in the southern constellation Tucana), located 210,000 light-years away.   view more (2005-01-12)

Hubble unveils colourful star birth region on 100 000th orbit milestone
In commemoration of the NASA/ESA Hubble Space Telescope completing its 100 000th orbit around the Earth in its 18th year of exploration and discovery, scientists have aimed Hubble to take a snapshot of a dazzling region of celestial birth and renewal.   view more (2008-08-11)

Glass sensors measure weathering effects
The corrosiveness of a specific atmosphere can be established in a few weeks by thin slices of special glass. The sensors are capable of monitoring the outdoor environment as well as indoors, for instance in sensitive production processes such as chip fabrication.   view more (2004-10-04)

Planet or failed star? One of smallest stellar companions seen by Hubble
Astronomers using the NASA/ESA Hubble Space Telescope have photographed one of the smallest objects ever seen around a normal star beyond our Sun. Weighing in at 12 times the mass of Jupiter, the object is small enough to be a planet.   view more (2006-09-11)

Carnegie Mellon researchers urge regulators to rethink strategies for soot emission
Carnegie Mellon University researchers say government officials need to adopt new ways of measuring and regulating the fine particles of smoke and soot so endemic to serious health problems and the global warming crisis.   view more (2007-03-02)

New findings blow a decade of assumptions out of the water
The Atlantic Ocean doesn't receive the mother lode of fixed nitrogen, the building block of life, after all. Instead, comparing fathom for fathom, the Pacific and Indian oceans experience twice the amount of nitrogen fixing as the Atlantic.   view more (2007-01-11)

How Life Originated In Space
Life originated on the Earth more than 3.5 billion years ago. However, the scientists are still disputing over the possible sources of the life origin. The matter is that life on our planet evolved from the molecular level to the level of bacteria organisms within 0.5 - 1 billion years, this period... view more (2002-04-12)

Scientists ramp up ability of poplar plants to disarm toxic pollutants
Scientists since the early '90s have seen the potential for cleaning up contaminated sites by growing plants able to take up nasty groundwater pollutants through their roots. Then the plants break certain kinds of pollutants into harmless byproducts that the plants either incorporate into their... view more (2007-10-16)

UK Astronomers look forward to looking back
When NASA launches its Space Infrared Telescope Facility (SIRTF) - the agency's fourth 'Great Observatory' - later this week, astronomers around the world will be looking forward to using one of the most powerful time machines ever built. Among those anticipating the opportunity to look back... view more (2003-08-19)

EU research suggests that PCBs damage sperm - but finds no dramatic effect on male fertility
Research by an EU-supported international team of scientists has shown that polychlorinated biphenyls (PCBs)[1]-synthetic organic chemicals found widely in the environment and absorbed in the diet - may damage sperm.   view more (2005-10-13)

Astronomers find grains of sand around distant stars
In a find that sheds light on how Earth-like planets may form, astronomers this week reported finding the first evidence of small, sandy particles orbiting a newborn solar system at about the same distance as the Earth orbits the sun. The report will be published online this week by the journal... view more (2008-03-13)

How do massive stars form?
Massive stars play a key role in the chemical and dynamical evolution of galaxies. The way massive stars form is still much debated among the astronomers' community: it is currently one of the hottest astrophysical topics.   view more (2005-11-09)
