Scientists Develop Method to Track Immune System Enzyme in Live Animals
Scientists supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) at the National Institutes of Health have created two mouse strains that will permit researchers to trace, in a live animal, the activity of an enzyme believed to play a crucial role both in the normal immune response as well as autoimmunity... view more...

Claritas Fossae tectonic region on Mars
These Mars Express images show Claritas Fossae, an ancient tectonic region on Mars, west of Solis Planum, a tectonic and volcanic area south-east of the Tharsis volcano group. The images were taken by the High-Resolution Stereo Camera (HRSC) on Mars in orbit 68 from an altitude of 271 km. The images are centred at 255.7° East and 30.9°... view more... (2004-03-31)
Where are the other `Earths` beyond the Solar System?
One of the most fascinating areas of astronomical research in recent years has been the search for other `Earths` circling Sun-like stars far beyond our Solar System. In recent years nearly 100 planets have been discovered in orbits around other stars, but none of these `exoplanets` remotely resembles the Earth. However, according to the latest... view more...

The origin of perennial water-ice at the South Pole of Mars
Thanks to data from ESA's Mars Express mission, combined with models of the Martian climate, scientists can now suggest how the orbit of Mars around the Sun affects the deposition of water ice at the Martian South Pole. view more (2007-07-16)
UI's Gurnett finds 'lumpy' ionosphere, glimpses of the subsurface of Mars
University of Iowa Space Physicist Don Gurnett and his UI colleagues report that a scientific instrument aboard the European Space Agency's (ESA) Mars Express spacecraft is working perfectly and that its data have so far revealed that Mars' ionosphere - part of the upper atmosphere - is very lumpy and complex, and that the instrument can... view more...

Challenges of landing on alien worlds
Three ESA missions are due to send down robotic `spaceprobes` when they arrive at their alien destinations. Since these craft will be going where no one has gone before, how can scientists be sure what it will be like down there? How do you ensure that your spaceprobe is prepared for anything? Experts take every precaution to ensure that these... view more... (2002-10-10)
It's a unisex brain with specific signals that trigger 'male' behavior
Research by Yale scientists shows that males and females have essentially unisex brains - at least in flies - according to a recent report in Cell designed to identify factors that are responsible for sex differences in behavior. view more (2008-05-01)
New insight into the link between genetics and obesity
Scientists have acquired new insight into how the 'obesity gene' triggers weight gain in some individuals. Their findings, reported online today in Science Express, could have implications for the future treatment of obesity as well as adult onset diabetes. view more (2007-11-09)
Ginkgo biloba extract: More than just for memory?
Researchers at Georgetown University Medical Center say they now have a clearer picture of how an extract from the leaves of the Ginkgo biloba tree reduces the risk of aggressive cancer in animal experiments. view more (2006-02-24)
Scientists Warn Of Injury Risk To Tennis Players As They Try To Emulate Their Wimbledon Heroes
With Wimbledon almost upon us, budding tennis players are once again inspired to pick up their racquets and try to emulate their heroes. But by adopting the tennis style of professional players, amateurs may be laying themselves open to serious back and shoulder injuries, according to research by University of Greenwich scientists. "A faster... view more... (2003-06-20)

Sailing the planets: Exploring Mars with guided balloons
Mars rovers, Spirit and Opportunity, have, by now, spent almost two years on the surface of Mars. They traveled several miles each, frequently stopping and analyzing scientific targets with their cameras, spectrometers and other instruments to uncover evidence of liquid water on Mars in the past. view more (2005-09-27)
Active submarine volcanoes found near Fiji
Several huge active submarine volcanoes, spreading ridges and rift zones have been discovered northeast of Fiji by a team of Australian and American scientists aboard the Marine National Facility Research Vessel, Southern Surveyor. view more (2008-06-19)
Gene therapy advance treats hemophilia in mouse models

Group Bragging Betrays Insecurity, Study Finds
From partisans at a political rally to fans at a football game, groups that engage in pompous displays of collective pride may be trying to mask insecurity and a low social status, suggests new research led by University of California, Davis, psychologists. view more (2008-10-21)
University of Iowa scientists explore function of 'junk DNA'
University of Iowa scientists have made a discovery that broadens understanding of a rapidly developing area of biology known as functional genomics and sheds more light on the mysterious, so-called "junk DNA" that makes up the majority of the human genome. view more (2006-11-14)
Study of planarians offers insight into germ cell development

Monkeys' ability to reflect on their thoughts may have implications for infants, autistic children
New research from Columbia's Primate Cognition Laboratory has demonstrated for the first time that monkeys could acquire meta-cognitive skills: the ability to reflect about their thoughts and to assess their performance. view more (2007-04-23)
Weekly contact with drug reps linked to unnecessary prescribing
General practitioners who see drug industry representatives at least once a week are more likely to express views that will lead to unnecessary prescribing then those who report less frequent contact, finds a study in this week’s BMJ. view more (2003-05-28)
