Dirty snow may warm Arctic as much as greenhouse gases
The global warming debate has focused on carbon dioxide emissions, but scientists at UC Irvine have determined that a lesser-known mechanism - dirty snow - can explain one-third or more of the Arctic warming primarily attributed to greenhouse gases.   view more (2007-06-07)

World first for Swedish researchers - mice born from transplanted wombs
Swedish scientists and doctors have transplanted uteri from one set of mice to another and produced normal healthy babies from the transplanted wombs. This is the first time that live births have been achieved from transplanted uteri in any species. It proves that transplanted uteri can harbour... view more (2003-06-28)

Cells use 'noise' to make cell-fate decisions
Electrical noise, like the crackle heard on AM radio when lightning strikes nearby, is a nuisance that wreaks havoc on electronic devices. But within cells, a similar kind of biochemical "noise" is beneficial, helping cells transform from one state to another, according to a new study led... view more (2007-03-23)

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)

CERN announces new start-up schedule for world's most powerful particle accelerator
Speaking at the 142nd session of the CERN Council today, the Organization's Director General Robert Aymar announced that the Large Hadron Collider (LHC) will start up in May 2008, taking the first steps towards studying physics at a new high-energy frontier.   view more (2007-06-25)

Stratospheric injections could help cool Earth, computer model shows
A two-pronged approach to stabilizing climate, with cuts in greenhouse gas emissions as well as injections of climate-cooling sulfates, could prove more effective than either approach used separately.   view more (2006-09-15)

A sound way to turn heat into electricity
University of Utah physicists developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling computers and radars.   view more (2007-06-04)

Arctic sea ice continues decline as temperatures rise
New satellite records monitored by a national team of collaborators show a four-year pattern of extremely low summer sea-ice coverage in the Arctic that continued in September 2005, which may be the result of warming temperatures and earlier spring melting.   view more (2005-09-29)

Molecule by molecule, new assay shows real-time gene activity
Chemists at Harvard University have developed the first technique providing a real-time, molecule-by-molecule "movie" of protein production in live cells.   view more (2006-03-16)

Climate change may affect East Asia differently to North Atlantic nations, study suggests
The extreme effects of climate change on the world depicted in the US blockbuster movie The Day After Tomorrow may not be quite true where East Asia is concerned.   view more (2006-06-21)

Climate Change Affecting Earth's Outermost Atmosphere
Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017   view more (2006-12-12)

Ecologists use oceanographic data to predict future climate change
Ecologists and oceanographers are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation.   view more (2008-11-07)

New research shows climate change triggers wars and population decline
Climate change may be one of the most significant threats facing humankind. A new study shows that long-term climate change may ultimately lead to wars and population decline.   view more (2007-11-26)

Model predicts a system's remaining life and links info to inventory decisions
New research at the Georgia Institute of Technology could soon make predicting the degradation and remaining useful life of mechanical and electronic equipment easier and more accurate, while significantly improving maintenance operations and spare parts logistics.   view more (2008-10-15)

XMM-Newton reveals a tumbling neutron star
Using data from ESA's XMM-Newton X-ray observatory, an international group of astrophysicists discovered that one spinning neutron star doesn't appear to be the stable rotator scientists would expect.   view more (2006-04-20)

Mice offer clues to the roots of human resilience
When faced with adversity, some people succumb to debilitating psychological diseases including posttraumatic stress disorder and depression, while others are able to remain remarkably optimistic.   view more (2007-10-19)

Were the first stars dark?
Perhaps the first stars in the newborn universe did not shine, but instead were invisible "dark stars" 400 to 200,000 times wider than the sun and powered by the annihilation of mysterious dark matter, a University of Utah study concludes   view more (2007-12-03)

Man may have caused pre-historic extinctions
New research shows that pre-historic horses in Alaska may have been hunted into extinction by man, rather than by climate change as previously thought.   view more (2006-05-05)

Hubble sees 'Comet Galaxy' being ripped apart by galaxy cluster
There are many galaxies of different shapes and sizes around us today. Roughly half are gas-poor elliptical-shaped galaxies with little new star formation activity, and half are gas-rich spiral and irregular galaxies with high star formation activity. Observations have shown that gas-poor galaxies... view more (2007-03-05)

ESA to select new Earth Explorer missions
An important milestone for ESA's Living Planet Programme is to be reached this spring when it will be decided which of the six candidate Earth Explorer missions are to be selected for development. Before decisions are taken, the user community is invited to express their views at the Earth Explorer... view more (2004-02-05)

First Components for the Wendelstein 7-X Fusion Device Ready
The first major components for the Wendelstein 7-X fusion experiment have been delivered to the Greifswald branch of Max-Planck-Institut für Plasmaphysik (IPP): a magnet coil, the first plasma vessel segment, vessel ports and a microwave transmitter for the plasma heating. The goal of fusion... view more (2004-03-02)

Research team says extraterrestrial impact to blame for Ice Age extinctions
What caused the extinction of mammoths and the decline of Stone Age people about 13,000 years ago remains hotly debated. Overhunting by Paleoindians, climate change and disease lead the list of probable causes. But an idea once considered a little out there is now hitting closer to home.   view more (2007-09-25)

Johns Hopkins housing and testing only 256-slice CT scanner in North America
Johns Hopkins Medicine has installed for three months of initial safety and clinical testing a 256-slice computed tomography (CT) scanner, believed to be the world's most advanced CT imaging software and machinery.   view more (2007-03-27)
