Mystery of missing hydrogen
Something vital is missing in the far distant reaches of the Universe: hydrogen - the raw material for stars, planets and possible life.   view more (2008-11-24)

Putting a green cap on garbage dumps
andfill sites produce the greenhouse gases, methane and carbon dioxide, as putrescible waste decays. Growing plants and trees on top of a landfill, a process known as 'Phytocapping', could reduce the production and release of these gases, according to Australian scientists writing in a forthcoming... view more (2008-11-24)

New material could make gases more transportable
Chemists at the University of Liverpool have developed a way of converting methane gas into a powder form in order to make it more transportable.   view more (2008-11-21)

Supercontinuum generation and soliton dynamics milestone achieved
A research team led by Fetah Benabid, University of Bath, has observed for the first time the simultaneous emission of two resonant dispersive waves by optical solitons (waves that maintain their shape while traveling at constant speeds).   view more (2008-11-21)

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... view more (2008-11-19)

APEX reveals glowing stellar nurseries
Illustrating the power of submillimetre-wavelength astronomy, an APEX image reveals how an expanding bubble of ionised gas about ten light-years across is causing the surrounding material to collapse into dense clumps that are the birthplaces of new stars. Submillimetre light is the key to... view more (2008-11-12)

Methane gas levels begin to increase again
The amount of methane in Earth's atmosphere shot up in 2007, bringing to an end a period of about a decade in which atmospheric levels of the potent greenhouse gas were essentially stable, according to a team led by MIT researchers.   view more (2008-10-30)

Classic experiments give new insight on life's origin
The building blocks of life may have emerged in volcanic eruptions on the early Earth, according to a new analysis of classic experiments performed more than fifty years ago.   view more (2008-10-17)

Ghostly glow reveals galaxy clusters in collision
A team of scientists, including astronomers from the Naval Research Laboratory (NRL), have detected long wavelength radio emission from a colliding, massive galaxy cluster which, surprisingly, is not detected at the shorter wavelengths typically seen in these objects.   view more (2008-10-16)

Astronomers get best view yet of infant stars at feeding time
Astronomers have used ESO's Very Large Telescope Interferometer to conduct the first high resolution survey that combines spectroscopy and interferometry on intermediate-mass infant stars.   view more (2008-10-13)

Arctic soil reveals climate change clues
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists.   view more (2008-10-08)

Advice from research: market visiting rights to Antarctica
Tourism on Antarctica is increasing and that can form a threat for the vulnerable South Pole area. Research from Maastricht University provides a possible solution: market the visitor rights to the highest bidder.   view more (2008-09-29)

The Wild, Hidden Cousin of SN 1987A
Over a decade after it exploded, one of the nearest supernovae in the last 25 years has been identified. This result was made possible by combining data from the vast online archives from many of the world's premier telescopes.   view more (2008-09-26)

Powerful Nearby Supernova Caught By Web
One of the nearest supernovas in the last 25 years has been identified over a decade after it exploded. This result was made possible by combining data from the vast online archives from many of the world's premier telescopes.   view more (2008-09-26)

A 'wild cousin' emerges from family tree of exploding stars
Astronomers may have discovered the relative of a freakishly behaving exploding star once thought to be the only one of its kind.   view more (2008-09-26)

IMPACTS: On the Threshold of Abrupt Climate Changes
Abrupt climate change is a potential menace that hasn't received much attention. That's about to change. Through its Climate Change Prediction Program, the U.S. Department of Energy's Office of Biological and Environmental Research (OBER) recently launched IMPACTS - Investigation of the Magnitudes... view more (2008-09-22)

International TGen-led team finds link between brain protein and Alzheimer's disease
Investigators at the Translational Genomics Research Institute (TGen) today announced a link between the brain protein KIBRA and Alzheimer's disease, a discovery that could lead to promising new treatments for this memory-robbing disorder.   view more (2008-09-16)

NASA study illustrates how global peak oil could impact climate
The burning of fossil fuels -- notably coal, oil and gas -- has accounted for about 80 percent of the rise of atmospheric carbon dioxide since the pre-industrial era. Now, NASA researchers have identified feasible emission scenarios that could keep carbon dioxide below levels that some scientists... view more (2008-09-11)

Fuel Emissions From Marine Vessels Remain a Global Concern
Marine vessels are no longer resting in a safe harbor. The forecast for clear skies and smooth sailing for oceanic vessels has been impeded by worldwide concerns of their significant contributions to air pollution and greenhouse gas emissions that impact the Earth's climate.   view more (2008-09-10)

Cataloguing invisible life: Microbe genome emerges from lake sediment
When entrepreneurial geneticist Craig Venter sailed around the world on his yacht sequencing samples of seawater, it was an ambitious project to use genetics to understand invisible ecological communities. But his scientific legacy was disappointing - a jumble of mystery DNA fragments belonging to... view more (2008-08-18)

Analysis of Lake Washington microbes shows the power of metagenomic approaches
Today's powerful sequencing machines can rapidly read the genomes of entire communities of microbes, but the challenge is to extract meaningful information from the jumbled reams of data.   view more (2008-08-18)

New robot scouts best locations for components of undersea lab
Like a deep-sea bloodhound, Sentry - the newest in an elite group of unmanned submersibles able to operate on their own in demanding and rugged environments - has helped scientists pinpoint optimal locations for two observation sites of a pioneering seafloor laboratory being planned off Washington... view more (2008-08-14)

Turning Waste Material into Ethanol
Say the word "biofuels" and most people think of grain ethanol and biodiesel. But there's another, older technology called gasification that's getting a new look from researchers at the U.S. Department of Energy's Ames Laboratory and Iowa State University. By combining gasification with... view more (2008-08-14)

PET scans may help assess presence of brain plaques related to Alzheimer's disease
A type of positron emission tomography (PET) scanning may be useful in a non-invasive assessment of the formation of Alzheimer's disease-related plaques in the brain, according to small study posted online today that will appear in the October 2008 print issue of Archives of Neurology, one of the... view more (2008-08-12)

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)
