Is the Salad Bar Safe? Produce Concerns Linger after Summer Scares
Widespread reports had most people afraid to eat tomatoes this summer and when tomatoes were vindicated, eating peppers became a fear. A University of Missouri food safety expert says there is only so much that can be done to assure produce is safe to eat. view more (2008-09-23)
Ultraviolet astronomy in danger
World astronomers are becoming very concerned about their ability to carry out observations in ultraviolet light following recent announcements about the future of the Hubble Space Telescope. Hubble is most famous for the clear images it gives of distant objects from its vantage point above the Earth's atmosphere. It is less well known that its... view more... (2004-03-23)
Testosterone Therapy Improves Sexual Function in Post-Menopausal Women
The addition of testosterone to hormone therapy in women after menopause enhances their sexual function. However, it may also reduce HDL cholesterol (the "good" cholesterol) in women, according to a systematic review of current evidence. view more (2005-10-24)
UCF, UCLA astronomers first to measure night and day on extrasolar planet
University of Central Florida Astronomy professor Joseph Harrington and University of California at Los Angeles professor Brad M. Hansen and their team have made the first direct observation of distinct day and night temperatures on a planet orbiting another star. view more (2006-10-13)
Home testing kit could help identify 'hidden' caffeine in beverages
If you've ever wondered whether your favorite coffee, tea or soda contains caffeine - despite its decaf label or the absence of caffeine on the ingredient list - then you may soon be able to test the beverage yourself. view more (2006-05-11)
Glasgow astronomers explain hot star disks
Astronomers have been puzzled for decades as to how the rings of hot gas surrounding certain types of star are formed. Now a team of scientists from the Universities of Glasgow and Wisconsin believe they have found the answer. The team studied a type of young, hot star, known as a "Be star", that has a disk of glowing gas around it, similar to the... view more... (2002-11-01)
Galaxy Cluster Takes It to the Extreme
Evidence for an awesome upheaval in a massive galaxy cluster was discovered in an image made by NASA's Chandra X-ray Observatory. The origin of a bright arc of ferociously hot gas extending over two million light years requires one of the most energetic events ever detected. view more (2007-05-31)
Hubble finds ring of dark matter
Astronomers have long suspected the existence of the invisible substance of dark matter as the source of additional gravity that holds together galaxy clusters. view more (2007-05-16)
Montana State team finds Yellowstone alga that detoxifies arsenic
Arsenic may be tough, but scientists have found a Yellowstone National Park alga that's tougher. view more (2009-03-10)
High-performance plasmas may make reliable, efficient fusion power a reality
In the quest to produce nuclear fusion energy, researchers from the DIII-D National Fusion Facility have recently confirmed long-standing theoretical predictions that performance, efficiency and reliability are simultaneously obtained in tokamaks, the leading magnetic confinement fusion device, operating at their performance limits. view more (2009-11-03)
Bacteria reveal secret of adaptation at Evolution Canyon
Bacteria living on opposite sides of a canyon have evolved to cope with different temperatures by altering the make-up of their 'skin', or cell membranes. Scientists have found that bacteria change these complex and important structures to adapt to different temperatures by looking at the appearance of the bacteria as well as their genes. view more (2008-07-28)
Foot-dragging Mars rover finds Yellowstone-like hot spring deposits
Deposits of nearly pure silica discovered by the Mars Exploration Rover Spirit in Gusev Crater formed when volcanic steam or hot water (or maybe both) percolated through the ground. view more (2008-05-23)
Does hotter mean healthier?
Phytophthora blight, caused by Phytophthora capsici, is a major plant disease that affects many crop species worldwide, including chile peppers in New Mexico. Farmers' observations suggested that Phytophthora capsici caused less damage in pepper crops of the hot pepper varieties than low-heat pepper varieties. view more (2009-02-04)
External Magnetic Field Causes The Puzzling Heating Of The Solar Corona
The Russian astrophysicists have theoretically modelled coronal loop oscillations and have shown that the plasma present in coronal loops is quite "normal". So, the puzzle of the Sun`s atmosphere heating remains unresolved. Coronal loops, immense magnetic arches more hot and dense than the coronal... view more... (2002-06-21)

Study: Sea stars bulk up to beat the heat
A new study finds that a species of sea star stays cool using a strategy never before seen in the animal kingdom. The sea stars soak up cold sea water into their bodies during high tide as buffer against potentially damaging temperatures brought about by direct sunlight at low tide. view more (2009-11-18)

Earth's crust melts easier than thought
Earth's crust melts easier than previously thought, scientists have discovered. In a paper published in this week's issue of the journal Nature, geologists report results of a study of how well rocks conduct heat at different temperatures. They found that as rocks get hotter in Earth's crust, they become better insulators and poorer conductors. view more (2009-03-19)
Giant Impact Near India -- Not Mexico -- May Have Doomed Dinosaurs
A mysterious basin off the coast of India could be the largest, multi-ringed impact crater the world has ever seen. And if a new study is right, it may have been responsible for killing the dinosaurs off 65 million years ago. view more (2009-10-16)
