Slowdown in tropical Pacific flow pinned on climate change
The vast loop of winds that drives climate and ocean behavior across the tropical Pacific has weakened by 3.5% since the mid-1800s, and it may weaken another 10% by 2100. view more (2006-05-04)
A dash of lime -- a new twist that may cut CO2 levels back to pre-industrial levels
Scientists say they have found a workable way of reducing CO2 levels in the atmosphere by adding lime to seawater. And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere, reports Cath O'Driscoll in SCI's Chemistry & Industry magazine published today. view more (2008-07-21)
Preservation of fresh-cut vegetables; a producer's and consumer's sake
In recent years, new food packaging concepts have been developed to respond on consumption trends towards mildly preserved, fresh convenient food products. Fresh-cut vegetables are an example of fresh-like, healthy convenience foods, developed in the '80s in the UK. Their market is yearly increasing with 25% in West Europe. Packaging fresh-cut... view more... (2002-03-19)
High-energy particles from violent black holes travel to Earth
Ultra-high-energy particles from just outside enormous, active black holes in nearby galaxies travel as far as 250 million light years to make it all the way to Earth, an international team of 400 physicists and astronomers from 17 countries reports in the Nov. 9 issue of the journal Science. view more (2007-11-12)
Rising surface ozone reduces plant growth and adds to global warming
Scientists from three leading UK research institutes have today released new findings that could have major implications for food production and global warming in the 21st century. view more (2007-07-26)
New study in JCSM finds that obesity can predict upper airway obstruction amongst children
In Australian children who snore, obesity, not age, is a significant, but only weak, predictor of upper airway obstruction during sleep, according to a study published in the April 15 issue of the Journal of Clinical Sleep Medicine (JCSM). view more (2008-04-15)
University of Hawai'i at Manoa team unravels the chemistry of Titan's hazy atmosphere
A team of University of Hawai'i at Mānoa researchers led by Ralf Kaiser, physical chemist at UH Mānoa, unraveled the chemical evolution of the orange-brownish colored atmosphere of Saturn's moon Titan, the only solar system body besides Venus and Earth with a solid surface and thick atmosphere. view more (2009-09-15)
Protective Storm in Space - a new explanation for the death of the dinosaurs
A shower of matter from space millions of years ago could have led to drastic changes in the Earth's climate, followed by the extinction of life on a massive scale, which also killed off the dinosaurs. This at least is a theory put forward by scientists from the University of Bonn. Normally, the solar wind acts as a shield against showers of... view more... (2002-06-04)
Chasing thundersnow could lead to more accurate forecasts
The job of one University of Missouri researcher could chill to the bone, but his research could make weather predicting more accurate. view more (2009-01-14)

Regular didgeridoo playing reduces snoring and daytime sleepiness, finds a study published online by the BMJ today. view more (2005-12-23)
Clearest video of lightning-generated 'sprites' high above thunderstorms captured
Researchers at Duke University's Pratt School of Engineering have captured the best images ever produced of "sprites" - mysterious flashes of light resembling giant undulating jellyfish that can occur above strong thunderstorms - using a high-speed camera that recorded thousands of video frames a second. view more (2006-02-16)
Greenhouse gas from English streams
English chalk streams are less healthy than we thought and are potentially even contributing to global warming, said Dr Mark Trimmer at a Science Media Centre press briefing today. view more (2007-12-11)
Getting closer to the Lord of the Rings
This time next year, ESA's Huygens spaceprobe will be descending through the atmosphere of Saturn's largest moon, becoming the first spacecraft to land on a body in the outer Solar System. Earlier this month, the giant ringed planet Saturn was closer to Earth than it will be for the next thirty years. All the planets orbit the Sun as if on a... view more... (2004-01-16)
Seismic images show dinosaur-killing meteor made bigger splash
The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago. view more (2008-01-24)
Follow the nitrogen to extraterrestrial life
The great search for extraterrestrial life has focused on water at the expense of a crucial element, say geobiologists at the University of Southern California. view more (2006-05-05)
Basque Country University researchers publish two articles in Nature on latest discoveries on Venus
Nature journal has published a series of articles devoted to the new discoveries by the European Space Agency's (ESA) Venus Express space probe made on our neighbouring planet. view more (2007-12-03)
Deep-sea rocks point to early oxygen on Earth
Red jasper cored from layers 3.46 billion years old suggests that not only did the oceans contain abundant oxygen then, but that the atmosphere was as oxygen rich as it is today, according to geologists. view more (2009-03-25)
Did dust bust the 2006 hurricane season forecasts?
A recent NASA study suggests that tiny dust particles may have foiled forecasts that the 2006 hurricane season would be another active one. view more (2007-03-29)
NASA Study Finds Warmer Future Could Bring Droughts
NASA scientists may have discovered how a warmer climate in the future could increase droughts in certain parts of the world, including the southwest United States. view more (2007-02-14)
NIST assists in solar stake-out to improve space weather forecasts
The sun is about to undergo unremitting scrutiny. About six times each minute of every hour for at least five years, a soon-to-be launched NASA satellite will measure the sun's quirky-and sometimes stormy-output of extreme ultraviolet (EUV) light. view more (2008-07-11)
