The case of the neutron star with a wayward wake
A long observation with NASA's Chandra X-ray Observatory revealed important new details of a neutron star that is spewing out a wake of high-energy particles as it races through space. view more (2006-06-02)
Climate gas could disrupt food chain
Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today. view more (2007-12-11)
Identification of carbon dioxide receptors in insects may help fight infectious disease
Mosquitoes don't mind morning breath. They use the carbon dioxide people exhale as a way to identify a potential food source. But when they bite, they can pass on a number of dangerous infectious diseases, such as malaria, yellow fever, and West Nile encephalitis. view more (2006-12-14)
Hubble sees the graceful dance of 2 interacting galaxies
A pair of galaxies, known collectively as Arp 87, is one of hundreds of interacting and merging galaxies known in our nearby Universe. Arp 87 was originally discovered and catalogued by astronomer Halton Arp in the 1970s. Arp's Atlas of Peculiar Galaxies is a compilation of astronomical photographs using the Palomar 200-inch Hale and the 48-inch... view more... (2007-10-31)
Supercomputer simulations shed light on cataclysmic variable flashes.
New supercomputer simulations may help explain periodic bursts of light emitted by compact binary star systems. view more (2005-03-31)
New population of faint protogalaxies discovered
Astronomers have found a new population of faint protogalaxies by taking the most sensitive spectroscopic survey ever of a time when the universe was only 15% of its present age. view more (2007-11-29)
Interstellar searchlights catch star factories in their beams
Jets of particles from newly formed stars are acting like searchlights, piercing the gloom of dark interstellar clouds to pick out clumps of gas that may become future stars. Astronomers at University College London (UCL) and the University of Barcelona have discovered how these interstellar beams mark the clumps with a distinctive chemical... view more... (2002-04-04)
UCLA researchers solve decade-old mystery
Environmentally friendly hydrogen gas fueled vehicles can dramatically reduce greenhouse gas emissions and lessen the country's dependence on sources of fossil fuel. Though several hydrogen vehicles exist on the market today, there is still much room for improvement in the way that hydrogen is stored on-board the vehicle. view more (2008-02-27)
Gas bubbles are taken under control
The system developed by the Moscow scientists with the financial assistance of the Russian Foundation for Basic Research and the Foundation for Assistance to Small Innovative Enterprises will instantly allow to detect and measure gas micro-bubbles being formed in blood inside the pump oxygenator. A small device which looks like some kind of a... view more... (2003-11-14)
'Rotten eggs' in the blood
Hydrogen sulphide (H2S) is a gas most commonly associated with the smell of stink bombs, sewage and rotten eggs, but a team of researchers from the Peninsula Medical School in the South West of England and King's College London have now identified a role for this gas in regulating blood pressure, according to research published today in the... view more...

New stars from old gas surprise astronomers
Evidence of star birth within a cloud of primordial gas has given astronomers a glimpse of a previously unknown mode of galaxy formation. The cloud, known as the Leo Ring, appears to lack the dark matter and heavy elements normally found in galaxies today. view more (2009-02-19)
Dark matter mystery deepens in cosmic 'train wreck'
Astronomers have discovered a chaotic scene unlike any witnessed before in a cosmic "train wreck" between giant galaxy clusters. view more (2007-08-17)
Report examines hidden costs of energy production and use
A new report from the National Research Council examines and, when possible, estimates "hidden" costs of energy production and use -- such as the damage air pollution imposes on human health -- that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them. view more (2009-10-20)
Separating uranium from plutonium
Moscow researchers have made the supercritical carbon dioxide work. Saturated with special reagents, carbon dioxide first extracts uranium from the spent nuclear fuel waste, then extracts plutonium and then flies away into the atmosphere. As a matter of fact, the spent nuclear fuel consists of multiple elements. First of all, this is uranium that... view more... (2003-08-08)
Cannibal stars like their food hot, XMM-Newton reveals
ESA's XMM-Newton has seen vast clouds of superheated gas, whirling around miniature stars and escaping from being devoured by the stars' enormous gravitational fields-giving a new insight into the eating habits of the galaxy's 'cannibal' stars. view more (2006-03-24)
Ancient geologic escape hatches mistaken for tube worms
Tubeworms have been around for millions of years and the fossil record is rich with their distinctive imprints. But a discovery made by U of C scientists found that what previous researchers had labeled as tubeworms in a formation near Denver, Colorado, are actually 70 million-year-old escape hatches for methane. view more (2009-02-05)
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)
Young stars in chaos
It is not only teenagers who like to congregate in intimate groups and disturb their neighbours and surroundings. As Matthew Bate (University of Exeter), will be explaining to the UK National Astronomy Meeting in Bristol on Friday 12 April, young stars also like to hang around in crowds and undergo chaotic close encounters with each other during... view more...

Hubble sees multiple star generations in a globular cluster
Hubble's observations of the massive globular cluster NGC 2808 provide evidence for three generations of stars that formed early in its life. This is a major upset for conventional theories that propose a single period of star birth. view more (2007-05-03)
Coal-mining hazard resembles explosive volcanic eruption, study shows
Worldwide, thousands of workers die every year from mining accidents, and instantaneous coal outbursts in underground mines are among the major killers. But although scientists have been investigating coal outbursts for more than 150 years, the precise mechanism is still unknown. view more (2009-10-01)
