Scientists to study impact of gulf oil spill on marine food webs
New reports are surfacing every day about the immediate impacts of the Deepwater Horizon oil spill on Gulf Coast wildlife, especially as the oil reaches the sensitive marshlands along the coast. But how will these communities be affected over time? Scientists currently know very little about how long it takes for the hydrocarbons and heavy metals in crude oil to work their way through marine food webs.
Blair to advise Silicon Valley group on climate
(AP) -- Former British Prime Minister Tony Blair is joining a Silicon Valley business as a senior adviser on environmental issues.
SETI Redux: Joining the Galactic Club
In this essay, David Schwartzman, a biogeochemist at Howard University in Washington D.C., explains why he thinks the aliens are out there, despite the fact that the search for extraterrestrial intelligence (SETI) has only found silence. He also outlines what we need to do for planet Earth to be initiated into the Galactic Club.
Straw residue helps keep nitrogen on the farm
Scientists are exploring ways to reduce non-point pollution from agriculture. A new study finds that using straw residue in conjunction with legume cover crops reduces leaching of nitrogen into waterways, but may lower economic return.
Astronauts make a last inspection of Atlantis
(AP) -- The Atlantis astronauts have some surveying work ahead of them, now that they're flying free of the International Space Station.
Martian meteorite may hold clues to water on the Red Planet
(PhysOrg.com) -- Scientists are examining fragments of a Martian meteorite to try to establish when water was freely flowing on the red planet.
Space shuttle Atlantis close to 120 million miles
(AP) -- Space shuttle Atlantis closed in on the 120 million-mile mark as its final voyage neared an end and astronauts inspected their ship in advance of Wednesday's landing.
BP vows $500 mln to study impact of oil spill
Oil giant BP pledged Monday up to 500 million dollars (405 million euros) to study the impact of the Deepwater Horizon rig spill on the Gulf of Mexico environment.
Oregon may build nation's first tsunami evacuation structure
Residents of a small Oregon coastal community are moving closer to the creation of something that's never before been built in the United States - a structure designed specifically to withstand a major earthquake and the force of a tsunami, and give people somewhere to run to for safety.
Nile delta natural gas potential is significant
An estimated 223 trillion cubic feet (tcf) (mean estimate) of undiscovered, technically recoverable natural gas are in the Nile Delta Basin Province, located in the Eastern Mediterranean region.
The Far Infrared Galaxy
(PhysOrg.com) -- Our Milky Way galaxy, like other spiral galaxies, has copious amounts of dust in its spiral arms. The dust absorbs starlight, thereby blocking our optical views, but at the same time it re-radiates the absorbed energy at far-infrared wavelengths.
Bandu begone: Tropical Cyclone 2A fading in Somalia
Early on Saturday, May 22, Tropical Storm 02A moved into the Gulf of Aden and was named "Bandu." At that time, Bandu had maximum sustained winds near 45 knots (52 mph) and was 50 miles north-northwest of Cape Guardafui, Somalia. NASA's Aqua satellite recently captured Bandu's fading thunderstorms over inland Somalia.
NASA develops enhanced search and rescue technologies
NASA, which pioneered the technology used for the satellite-aided search and rescue capability that has saved more than 27,000 lives worldwide since its inception nearly three decades ago, has developed new technology that will more quickly identify the locations of people in distress and reduce the risk of rescuers.
Stellar Shrapnel Seen in Aftermath of Explosion
(PhysOrg.com) -- This beautiful composite image shows N49, the aftermath of a supernova explosion in the Large Magellanic Cloud. A new long observation from NASA's Chandra X-ray Observatory, shown in blue, reveals evidence for a bullet-shaped object being blown out of debris field left over from an exploded star.
Rainy Spells Extended For Europe
Like a patient getting a regular checkup, our understanding of climate gets poked and probed in a number of ways. And just as doctors keep a regular clipboard of vital statistics such as blood pressure and weight, meteorologists measure long-term weather patterns hoping to find interesting patterns.
Scientist proposes method to quantify Gulf oil spill
While the world has reacted with shock and anger to the massive amounts of oil leaking into the Gulf of Mexico as a result of the Deepwater Horizon platform blowout, a UC Santa Barbara scientist has proposed that methane gas dissolved into the waters of the Gulf holds the key to calculating the magnitude of the spill.
No activity at Iceland volcano, eruption could be over: expert
Iceland's Eyjafjoell volcano is no longer in activity, a geophysicist said Sunday, raising hopes the eruption which has heavily disrupted European flights for more than a month could be over.
Odds are about 1-in-3 that a mega-earthquake will hit the Northwest in the next 50 years
The major earthquakes that devastated Chile earlier this year and which triggered the catastrophic Indonesian tsunami of 2004 are more than just a distinct possibility to strike the Pacific Northwest coast of the United States, scientists say.
Helium pair have regular violent flare ups
(PhysOrg.com) -- A team of astronomers led by Dr Gavin Ramsay of Armagh Observatory have spotted violent eruptions from an interacting pair of stars that orbit around each other every 25 minutes. Unusually, these outbursts take place at regular and predictable intervals, erupting every two months. The new observations were made using the fully robotic Liverpool Telescope sited in the Canary Islands and the orbiting Swift observatory. The results will appear in the journal Monthly Notices of the Royal Astronomical Society.
WISE Telescope has Heart and Soul
(PhysOrg.com) -- NASA's Wide-field Infrared Survey Explorer, or WISE, has captured a huge mosaic of two bubbling clouds in space, known as the Heart and Soul nebulae. The space telescope, which has completed about three-fourths of its infrared survey of the entire sky, has already captured nearly one million frames like the ones making up this newly released mosaic.
Global warming's influence on El Nino still unknown
(PhysOrg.com) -- The climate of the Pacific region will undergo significant changes as atmospheric temperatures rise but scientists can not yet identify the influence it will have on the El Nino-Southern Oscillation (ENSO) weather phenomenon.
Weird orbits of neighbors can make 'habitable' planets not so habitable
Astronomers hunting for planets orbiting nearby stars similar to the sun are looking for signs of rocky, Earth-like planets in a "habitable" zone, where conditions such as temperature and liquid water remain stable enough to support life.
Pollution dispersion research aids understanding of 2002 break-up of Antarctic ozone hole
The eruption of the volcano in Iceland has drawn attention to air flow patterns, as airlines lost millions of dollars and travelers remained stranded for days to weeks, as particles from the natural disaster traveled over Europe, forcing closures of major airports.
Out of Whack Planetary System Offers Clues to a Disturbed Past
(PhysOrg.com) -- Astronomers are reporting today the discovery of a planetary system way out of tilt, where the orbits of two planets are at a steep angle to each other. This surprising finding will impact theories of how multi-planet systems evolve, and it shows that some violent events can happen to disrupt planets' orbits after a planetary system forms, say researchers.
Phoenix Mars Lander is Silent, New Image Shows Damage
(PhysOrg.com) -- NASA's Phoenix Mars Lander has ended operations after repeated attempts to contact the spacecraft were unsuccessful. A new image transmitted by NASA's Mars Reconnaissance Orbiter shows signs of severe ice damage to the lander's solar panels.

What genes help blossoms last longer?
Some cut flowers and potted plants are better than others at fending off the aging process, known as senescence. To help tomorrow's blooms stay fresh longer, Agricultural Research Service (ARS) plant physiologist Cai-Zhong Jiang is investigating the gene-controlled mechanisms of plants' aging.
Male antelopes trick females into extra sex opportunities
Scientists have caught male topi antelopes in the act of faking fear in front of females in heat as a way to improve their chances of having sex.
Can bacteria make you smarter?
Exposure to specific bacteria in the environment, already believed to have antidepressant qualities, could increase learning behavior according to research presented today at the 110th General Meeting of the American Society for Microbiology in San Diego.
