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)

Day-long drivers at risk of cardiovascular problems as a result of traffic pollution
Exposure to fine particles and pollutants that accumulate in cars driving at varying speeds in road traffic enhances the likelihood of thrombosis, inflammation and alters the regularity of the heart rhythm. A study published today in the journal Particle and Fibre Toxicology raises concerns about... view more (2004-12-07)

Common aquatic animals show extreme resistance to radiation
Scientists at Harvard University have found that a common class of freshwater invertebrate animals called bdelloid rotifers are extraordinarily resistant to ionizing radiation, surviving and continuing to reproduce after doses of gamma radiation much greater than that tolerated by any other animal... view more (2008-03-26)

Unusual meteorite unlocks treasure trove of solar system secrets
An unusual meteorite that fell on a frozen lake in Canada five years ago has led a Florida State University geochemist to a breakthrough in understanding the origin of the chemical elements that make up our solar system.   view more (2005-09-28)

Infrared Images of an Infant Solar System
ESO telescopes have detected a strange-looking object. Using the ESO 3.6-m New Technology Telescope and the Very Large Telescope (VLT), a team of astronomers [1] have discovered a dusty and opaque disk surrounding a young solar-type star in the outskirts of a dark cloud in the Milky Way. It was... view more (2002-05-14)

How Iron Gets into the North Pacific
Most oceanographers have assumed that, in the areas of the world's oceans known as High Nutrient, Low Chlorophyll (HNLC) regions, the iron needed to fertilize infrequent plankton blooms comes almost entirely from wind-blown dust.   view more (2008-03-20)

Key to lung cancer chemo resistance revealed
Scientists at Johns Hopkins have discovered how taking the brakes off a "detox" gene causes chemotherapy resistance in a common form of lung cancer.   view more (2006-10-11)

U-M scientists simulate effects of blowing Mars dust
Gusting winds and the pulsating exhaust plumes from the Phoenix spacecraft's landing engines could complicate NASA's efforts to sample frozen soil from the surface of Mars, according to University of Michigan atmospheric scientist Nilton Renno.   view more (2007-06-18)

Newly detected air pollutant mimics damaging effects of cigarette smoke
A previously unrecognized group of air pollutants could have effects remarkably similar to harmful substances found in tobacco smoke, Louisiana scientists are reporting in a study scheduled for presentation today at the 236th National Meeting of the American Chemical Society.   view more (2008-08-18)

Atmospheric chemistry - air quality and climate
Air quality has improved dramatically over the past 50 years. Professor Mike Pilling, Head of Physical Chemistry at the University of Leeds, will reveal the latest about air quality research at the Festival of Science today.   view more (2004-09-06)

Eclipsing brown dwarfs provide new key to the star formation process
Pity the brown dwarf. It's too large to be a planet, but too small to be a star.   view more (2006-03-16)

Endangered polar heritage
There are 76 sites on the official list of historic sites and monuments in Antarctica. 11 of them are, or used to be, Norwegian. Cultural heritage is a non-renewable resource endangered by environmental pollutants and increased tourism. -We need a lot more research on Norwegian historic sites in... view more (2004-08-04)

Drying wood with steam
Large quantities of wood chips are dried for the production of chip-board. Modifications to a widely implemented large-scale industrial process lead to enormous savings: 15 percent less heat energy is required and emissions are markedly reduced.   view more (2002-02-01)

Research suggests social factors behind higher schizophrenia rate in British African-Caribbeans
Unemployment and earlier separation from both parents may be key factors behind the higher rates of schizophrenia in British African-Caribbeans, according to new research by a scientist at The Centre for Caribbean Medicine, King's College London.   view more (2002-06-19)

NASA aims to clear up mystery of elusive clouds at edge of space
NASA is preparing to launch the Aeronomy of Ice in the Mesosphere (AIM) spacecraft, the first mission dedicated to exploration of mysterious ice clouds that dot the edge of space in Earth's polar regions.   view more (2007-04-12)

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)

Computer model helps combat air pollution across Europe
The key role of multidisciplinary research in developing a landmark intergovernmental strategy to combat air pollution across Europe will be considered by Professor Helen ApSimon of Imperial College London in her inaugural lecture, A lot of Hot Air - Transboundary Air Pollution Over Europe.   view more (2003-01-28)

Did you know? The oldest organisms live in waste repositories
Some of the oldest organisms - Archaea - live in waste repositories. These microorganisms have lived on Earth for 3.8 billion years and some of them can produce methane, used as a renewable energy source. Cemagref scientists are trying to enhance their activities so that they produce methane more... view more (2003-06-11)

U.S.-German Research Consortium Sequences Genome of Versatile Soil Microbe
In a successful transatlantic collaboration, scientists at The Institute for Genomic Research (TIGR) in Rockville, MD, and at four research centers in Germany have deciphered and analyzed the complete genome of a bacterium, Pseudomonas putida, that has the potential to be used to remediate organic... view more (2002-12-03)

Immune system pathway identified to fight allergens, asthma
For the first time, researchers from the University of Pittsburgh School of Medicine have identified genetic components of dendritic cells that are key to asthma and allergy-related immune response malfunction.   view more (2008-05-08)

Key mechanism for star formation found?
The team, led by Dan Clemens, from Boston University Institute for Astrophysical Research, examined a distant cloud of gas and dust called GF9, located about 1300 light years away. It shows a filamentary or wispy appearance, with dark "globules" distributed along its length. The new observation... view more (1999-06-03)

Sea salt worsens coastal air pollution: study
Air pollution in the world's busiest ports and shipping regions may be markedly worse than previously suspected, according to a new study showing that industrial and shipping pollution is exacerbated when it combines with sunshine and salty sea air.   view more (2008-04-09)

Precise cut for sparkling jewels
Rubies, emeralds and tourmalines can only sparkle with the right cut. Since early this year, a fully automatic machine has undertaken this grinding process for Paul Wild GmbH. It saves up to 30 percent of the precious material and grinds the gems with greater precision.   view more (2008-04-09)

Galaxies gone wild!
Interacting galaxies are found throughout the Universe, sometimes as dramatic collisions that trigger bursts of star formation, on other occasions as stealthy mergers that result in new galaxies.   view more (2008-04-24)
