Wilkins Ice Shelf hanging by its last thread
The Wilkins Ice Shelf is experiencing further disintegration that is threatening the collapse of the ice bridge connecting the shelf to Charcot Island. Since the connection to the island in the image centre helps to stabilise the ice shelf, it is likely the break-up of the bridge will put the remainder of the ice shelf at risk. view more (2008-07-11)
Europeans Will Adjust To Global Warming But Will Still Die Of Cold
(Heat related mortality in warm and cold regions of Europe: observational study) BMJ Volume 321, pp 670 - 673 (Editorial : Saving lives in extreme weather in summer : pp 650 ? 651) Heat related deaths start at higher temperatures in hot regions of Europe compared to cold regions, suggesting that people have adjusted successfully to differences in... view more...

Impact of Climate Warming on Polar Ice Sheets Confirmed
In the most comprehensive survey ever undertaken of the massive ice sheets covering both Greenland and Antarctica, NASA scientists confirm climate warming is changing how much water remains locked in Earth's largest storehouse of ice and snow. view more (2006-03-09)
New brain cells listen before they talk
Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells-a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or neurodegeneration, Yale School of Medicine... view more...

Strengthening case for life on Mars - CMD19CMMP with The Physics Congress 2002
When it was announced last month that the Mars Odyssey satellite had found water ice beneath the planet`s frozen carbon dioxide south polar ice cap, "I felt excited!" says Dr Lidija Siller, a physicist from the University of Newcastle. "I believe that the data I have explains how this water became trapped underneath the surface". Dr Siller will be... view more... (2002-03-26)
New material brings hydrogen fuel, cheaper petrochemicals closer to reality
A rubbery material that can purify hydrogen efficiently in its most usable form for fuel cells and oil refining has been developed by a chemical engineering group at The University of Texas at Austin. view more (2006-02-03)
Global warming may delay recovery of stratospheric ozone
Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a new study suggests. This change might take a toll on public health. view more (2009-02-05)
By ice floe to the North Pole
At the end of August, an unusual expedition under Russian leadership will leave for the Arctic Ocean. One of the participants is Jürgen Graeser of the Alfred Wegener Institute for Polar and Marine Research, one of the research centres of the Helmholtz Association. view more (2007-07-23)
Cause of mussel poisoning identified
The origin of the neurotoxin azaspiracid has finally been identified after a search for more than a decade. view more (2009-03-25)
Comparing chimp and human DNA
Scientists look to the chimpanzee genome to better understand what is uniquely human about our own. One goal is to find DNA elements that show evidence of rapid evolution in the human lineage. view more (2006-10-13)
Scientists identify brain regions that decide where we look
Scientists have found the brain regions that decide where we look, and where to direct our eyes when we're faced with a difficult choice, such as looking someone straight in the eye or looking away. view more (2005-01-24)
New evidence points to oceans on Mars
Scientists have found new evidence to support the presence of large oceans on Mars in the past. view more (2007-06-14)
Mathematics and climate change
In 1994, University of Utah mathematician Ken Golden went to the Eastern Weddell Sea for the Antarctic Zone Flux Experiment. The sea's surface is normally covered with sea ice, the complex composite material that results when sea water is frozen. view more (2009-04-13)
Arctic marine mammals on thin ice
The loss of sea ice due to climate change could spell disaster for polar bears and other Arctic marine mammals. The April Special Issue of Ecological Applications examines such potential effects, puts them in historical context, and describes possible conservation measures to mitigate them. view more (2008-04-24)
Ice Volcanoes on Saturn's Moon Enceladus
Scientists from the Max Planck Institute for Nuclear Physics and the University of Potsdam have found ice volcanoes-or what could be called "ice geysers"-on the surface of Saturn's moon Enceladus. view more (2006-03-15)
Siberian lakes burp "time-bomb" greenhouse gas
Frozen bubbles in Siberian lakes are releasing methane, a greenhouse gas, at rates that appear to be "... five times higher than previously estimated" and acting as a positive feedback to climate warming, said Katey Walter, in a paper published today in the journal Nature. view more (2006-09-08)
Integral identifies supernova rate for Milky Way
Using ESA's Integral observatory, an international team of researchers has been able to confirm the production of radioactive aluminium (Al 26) in massive stars and supernovae throughout our galaxy and determine the rate of supernovae-one of its key parameters. view more (2006-01-09)
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)
Experts meet on need for new rules to govern world's fragile polar regions
A new co-ordinated international set of rules to govern commercial and research activities in both of Earth's polar regions is urgently needed to reflect new environmental realities and to temper pressure building on these highly fragile ecosystems, according to several of the experts convening in Iceland for a UN-affiliated conference marking the... view more...

Parts of brain involved in social cognition may be in place by age 6
Social cognition-the ability to think about the minds and mental states of others-is essential for human beings. In the last decade, a group of regions has been discovered in the human brain that are specifically used for social cognition. view more (2009-07-15)
