Antarctic Research Helps Shed Light On Climate Change On Mars (August 30, 2008) -- Eroded gullies on the flanks of Martian craters may have been formed by snowmelt as recently as a few hundred thousand years ago and in sites once occupied by glaciers. Similar conditions can be found in Antarctica's McMurdo Dry Valleys. Rather than being a dead planet, the new data are consistent with dynamic climate changes on Mars. ... > full story
Tiny 3-D Ultrasound Probe Guides Catheter Procedures (August 30, 2008) -- An ultrasound probe small enough to ride along at the tip of a catheter can provide physicians with clearer real-time images of soft tissue without the risks associated with conventional X-ray catheter guidance. ... > full story
Scientists Discover Why Flies Are So Hard To Swat (August 29, 2008) -- Over the past two decades, Michael Dickinson has been interviewed by reporters hundreds of times about his research on the biomechanics of insect flight. One question from the press has always dogged him: Why are flies so hard to swat? "Now I can finally answer," says Dickinson, the Esther M. and Abe M. Zarem Professor of Bioengineering at the California Institute of Technology. ... > full story
New Approach To Detect Early Progression Of Brain Tumors Identified (August 29, 2008) -- New research suggests a certain type of MRI scanning can detect when a patient is failing brain tumor treatment before symptoms appear. The results of the study pave the way for a proactive treatment approach. ... > full story
Katrina And Rita Provide Glimpse Of What Could Happen To Offshore Drilling If Gustav Hits Gulf (August 29, 2008) -- Shortly after Hurricanes Katrina and Rita hit the US, engineers studied damage done to offshore drilling platforms in the Gulf of Mexico. If tropical storm Gustav strengthens into a Category 3 hurricane, as forecasters are predicting, the damage could be extensive. ... > full story
Atomic Bomb Effect Results In Adult-onset Thyroid Cancer Identified (August 29, 2008) -- Radiation from the atomic bomb blasts in Hiroshima and Nagasaki, Japan, in 1945, likely rearranged chromosomes in some survivors who later developed papillary thyroid cancer as adults, according to Japanese researchers. ... > full story
Rosetta Spacecraft On Its Way To Meet Asteroid Steins (August 29, 2008) -- ESA’s Rosetta spacecraft will make a historic encounter with asteroid (2867) Steins on 5 September 2008. The spacecraft will rendezvous with the asteroid in the course of its first incursion into the asteroid belt located between the orbits of Mars and Jupiter, while on its way to comet 67/P Churyumov-Gerasimenko. ... > full story
Saving Lives Through Smarter Hurricane Evacuations (August 29, 2008) -- Hundreds of lives and hundreds of millions of dollars could potentially be saved if emergency managers could make better and more timely critical decisions when faced with an approaching hurricane. Now, an MIT graduate student has developed a computer model that could help do just that. ... > full story
Origin Of High Energy Emission From Crab Nebula Identified (August 29, 2008) -- Another piece of the jigsaw in understanding how neutron stars work has been put in place following the discovery by scientists of the origin of the high energy emission from rotation-powered pulsars. ... > full story
Quantum 'Traffic Jam' Revealed: Findings May Help Get Current Flowing At Higher Temperatures (August 29, 2008) -- Scientists at Brookhaven National Laboratory and collaborators have uncovered the first experimental evidence for why the transition temperature of high-temperature superconductors cannot simply be elevated by increasing the electrons' binding energy. The research demonstrates how, as electron-pair binding energy increases, the electrons' tendency to get caught in a quantum mechanical "traffic jam" overwhelms the interactions needed for the material to act as a superconductor -- a freely flowing fluid of electron pairs. ... > full story
Robots Learn To Predict Where Their Leader Is Going, And Follow Along (August 29, 2008) -- Researchers have come up with a control system that allows a robot to pick up on cues that the leader is about to turn, predict where it is going and follow it. ... > full story
Explosives Go 'Green' ... And Get More Precise (August 29, 2008) -- Certain explosives may soon get a little greener and a little more precise. Researchers have added unique green solvents (ionic liquids) to an explosive called TATB (1,3,5-triamino-2,4,6-trinitrobenzene) and improved the crystal quality and chemical purity of the material. ... > full story
