NASA's Mars rovers set surface longevity record (May 22, 2010) -- NASA's Mars Exploration Rover Project will pass a historic Martian longevity record on May 20. The Opportunity rover will surpass the duration record set by NASA's Viking 1 Lander of six years and 116 days operating on the surface of Mars. The effects of favorable weather on the red planet could also help the rovers generate more power. ... > full story
Low-cost, ultra-fast DNA sequencing brings diagnostic use closer (May 22, 2010) -- Researchers show the viability of a novel, more efficient method to sequence DNA using nanopores. By doing it fast and inexpensively, this method brings routine use of DNA sequencing in medical diagnostics closer to reality. ... > full story
Hubble finds a star eating a planet (May 21, 2010) -- The hottest known planet in the Milky Way galaxy may also be its shortest-lived world. The doomed planet is being eaten by its parent star, according to observations made by a new instrument on NASA's Hubble Space Telescope, the Cosmic Origins Spectrograph (COS). The planet may only have another 10 million years left before it is completely devoured. ... > full story
Presence of chemical in smoker's breath indicates person has smoked in last three days (May 21, 2010) -- If you smoke, your breath contains 2,5-dimethylfuran. A team of Catalan researchers have proved that the presence of this chemical compound indicates that a person has smoked in the last three days. This substance does not appear in the breath of non-smokers, unless they have been in direct contact with tobacco smoke for a long time. ... > full story
Better ways to inhibit blood clots revealed by new study (May 21, 2010) -- A new study reveals factors that improve the performance of synthetic fibrin "knobs", which bind to "holes" on fibrinogen molecules to prevent blood clot formation. The study also identifies a novel synthetic knob that displays a 10-fold higher affinity for holes than current synthetic knobs. ... > full story
Arsenic in playgrounds nothing to worry about, study suggests (May 21, 2010) -- Pressure-treated wooden playground structures do not live up to the bad reputation they have earned as being harmful to children, according to the findings of a new study. ... > full story
Probing the dark side of the universe: In search of primordial gravitational waves (May 21, 2010) -- Much like ripples moving across a pond, gravitational waves waves stretch the fabric of space itself as they pass by. If detected, these elusive waves could provide an unprecedented view of the earliest moments of our universe. Researchers are exploring the most likely detection method of these waves. ... > full story
To improve lung cancer diagnosis, good medicine is a polymer pill (May 21, 2010) -- Doctors may soon be able to diagnose lung cancer more effectively, thanks to scientists who have found ways both to increase the accuracy of computed tomography scans and to lessen the amount of time necessary to perceive telltale changes in lung tissue. ... > full story
Scientists discover the molecular heart of collective behavior (May 21, 2010) -- A group of scientists seeking the answer to the mystery of collective motion has found strong evidence pointing to the idea that collective behavior can arise in cells that initially may not be moving at all, but are prodded into action by an external agent such as a chemical. ... > full story
Non-invasive technique could distinguish fertile and infertile human sperm cells (May 21, 2010) -- Scientists in Germany have developed a non-invasive technique that within seconds can distinguish healthy fertile and infertile sperm cells by collecting the spectral chemical fingerprint. The method has the potential for a novel fertility technology and a test scheme which does not only rely on morphological characteristics, but also utilizes chemical signatures. ... > full story
'Scrubbing' chemical-contaminated buildings clean with lasers (May 21, 2010) -- While no terrorist has managed to deploy a dirty bomb, the same cannot be said of chemical agents. In a series of tests still underway researchers are using lasers to scrub surfaces clean of sulfur mustard gas and VX, a nerve agent. The tests have proved successful so far, even on complex, porous surfaces like concrete. ... > full story
Seeing moire in graphene (May 21, 2010) -- Researchers have demonstrated that atomic scale moire patterns, an interference pattern that appears when two or more grids are overlaid slightly askew, can be used to measure how sheets of graphene are stacked and reveal areas of strain. ... > full story
