Mars Express mission extended
ESA's Mars Express mission has been extended by one Martian year, or about 23 months, from the beginning of December 2005. view more (2005-09-23)
New study indicates moderate exercise may protect against colds
A moderate exercise program may reduce the incidence of colds. A study published in the November issue of The American Journal of Medicine, led by researchers at Fred Hutchinson Cancer Research Center, found that otherwise sedentary women who engaged in moderate exercise had fewer colds over a one year period than a control group. view more (2006-10-26)
Saturn's winds are variable
A team of astrophysicists at the University of the Basque Country has detected, for the first time ever, changes in Saturn's winds. The research has merited front page coverage in the scientific magazine, Nature. The winds blowing around Saturn and Jupiter are special. Unlike those of the rest of the planets, these move in an eastwards direction... view more... (2003-06-09)

Climate change and the rise of atmospheric oxygen
Today's climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. view more (2006-03-23)
The life histories of the earliest land animals
The fossil record usually shows what adult animals looked like. But the appearance and lifestyle of juvenile animals often differ dramatically from those of the adults. view more (2009-04-21)
Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science. view more (2007-06-25)
NSF / NASA 'Firefly' CubeSat Mission to Study Link Between Lightning and Terrestrial Gamma Ray Flashes
Massive energy releases occur every day in the upper reaches of Earth's atmosphere. Lightning may give rise to these bursts of radiation. However, unlike the well-known flashes of light and peals of thunder familiar to Earth-dwellers, these energy releases are channeled upward and can be detected only from space. view more (2008-11-18)
Mars and Venus are surprisingly similar
Using two ESA spacecraft, planetary scientists are watching the atmospheres of Mars and Venus being stripped away into space. The simultaneous observations by Mars Express and Venus Express give scientists the data they need to investigate the evolution of the two planets' atmospheres. view more (2008-03-06)
Second Cluster pair soar into the skies above Baikonur
At 17.13 local time (13.13 CEST) today, the second pair of Cluster spacecraft lifted off from pad 6 at Baikonur Cosmodrome aboard a Soyuz-Fregat launch vehicle. On a scorching summer afternoon, with temperatures well over 40°C, conditions were perfect for this second act in the Cluster launch drama. Topped by a giant fairing emblazoned with a... view more...

Polar clouds take a 'bite' out of meteoric iron
Polar clouds are known to play a major role in the destruction of Earth's protective ozone layer, creating the springtime 'ozone hole' above Antarctica. Now, scientists have found that polar clouds also play a significant role in removing meteoric iron from Earth's atmosphere. Polar clouds have been widely studied in recent years, because of their... view more... (2004-04-14)
Mountain winds may create atmospheric hotspots
Rapidly fluctuating wind gusts blowing over mountains and hills can create "hotspots" high in the atmosphere and significantly affect regional air temperatures. view more (2005-10-18)
Facial attraction -- choice of sexual partner shaped the human face
Men with large jaws, flaring cheeks and large eyebrows are sexy, at least in the eyes of our ancestors, researchers at the Natural History Museum have discovered. view more (2007-08-14)
NASA research reveals climate warming reduces ocean food supply
In a NASA study, scientists have concluded that when Earth's climate warms, there is a reduction in the ocean's primary food supply. This poses a potential threat to fisheries and ecosystems. view more (2006-12-07)
Ice clouds put Mars in the shade
Until now, Mars has generally been regarded as a desert world, where a visiting astronaut would be surprised to see clouds scudding across the orange sky. However, new results show that the arid planet possesses high-level clouds that are sufficiently dense to cast a shadow on the surface. view more (2008-01-17)
New research forecasts better weather forecasts
A Purdue University researcher and his team have used improved satellite imaging and powerful computer modeling to more accurately forecast the likelihood and intensity of storms and tornados. view more (2006-03-01)
Some of Earth's climate troubles should face burial at sea, scientists say
Making bales with 30 percent of global crop residues - the stalks and such left after harvesting - and then sinking the bales into the deep ocean could reduce the build up of global carbon dioxide in the atmosphere by up to 15 percent a year, according to just published calculations. view more (2009-01-29)
Phytoplankton bounce back from abrupt climate change
Marine sediment cores contain calcareous plankton - single-celled organisms with a coating or shell of calcium carbonate - as fossils. These tiny photosynthesizing plants float in the ocean and move with the currents. view more (2006-02-17)
Calcium supplements fail to prevent bone fractures in children
Children taking such supplements are have only small improvements in bone density, which are unlikely to reduce fracture risk, says the study carried out by researchers at the Menzies Research Institute in Australia and other approaches could be more beneficial such as increasing vitamin D concentrations and eating more fruit and vegetables. view more (2006-09-15)
Will The Leonids Go Out With A Bang?
Anyone willing to brave the early morning cold on 19 November may be rewarded with one of Nature's most spectacular firework displays - a major meteor storm. This year's Leonid meteor shower is expected to provide the last great storm for at least 30 years, and possibly the biggest in the 21st century. With meteor numbers predicted to reach or... view more... (2002-11-15)
