Meteor no longer prime suspect in great extinctionThe greatest mass extinction in Earth's history also may have been one of the slowest, according to a study that casts further doubt on the extinction-by-meteor theory.
Agricultural soil erosion not contributing to global warming
Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, according to research published online in Science. The study was carried out by an international team led by researchers at the Katholieke Universiteit Leuven, Belgium, the University of Exeter, UK, and the University of California, Davis.
New population of iberian lynx raises hope
Spanish authorities have announced they have discovered a previously unknown population of Iberian lynx, triggering hope for one of the world's most endangered cat species, said World Wildlife Fund.

Research sheds new light on how diseases jump across species
Researchers at the University of Leeds have made a breakthrough in understanding a virus which poses one of the greatest global disease threats to wild carnivores including lions, African wild dogs and several types of seal.
Study reveals lakes a major source of prehistoric methaneA team of scientists led by a researcher at the University of Alaska Fairbanks has identified a new likely source of a spike in atmospheric methane coming out of the North during the end of the last ice age.
Rise in atmospheric CO2 accelerates as economy grows, natural carbon sinks weakenHuman activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening.
Scientist studies 'fossil earthquakes,' possible key to understanding future quakes
A Colorado State researcher is studying Earth's ancient earthquakes, or fossil earthquakes, to get a better understanding of how and why earthquakes happen.
Seismologists see earth's dynamic interior as interplay of temperature, pressure, chemistrySeismologists have recast their understanding of the inner workings of Earth from a relatively homogeneous environment to one that is highly dynamic and chemically diverse.
Staph-killing properties of clay investigatedWhat makes some clays such powerful antimicrobial agents capable of killing MRSA and other virulent bacteria? It's a question that University at Buffalo researchers have been studying for several years.
Dead clams tell many talesInventories of living and dead organisms could serve as a relatively fast, simple and inexpensive preliminary means of assessing human impact on ecosystems. The University of Chicago's Susan Kidwell explains how measuring the degree of live-dead mismatch could be used as an ecological tool in the Oct. 26 early online edition of the Proceedings of the National Academy of Sciences.
Dinosaur deaths outsourced to india? A series of monumental volcanic eruptions in India may have killed the dinosaurs 65 million years ago, not a meteor impact in the Gulf of Mexico. The eruptions, which created the gigantic Deccan Traps lava beds of India, are now the prime suspect in the most famous and persistent paleontological murder mystery, say scientists who have conducted a slew of new investigations honing down eruption timing.
Scientists discover fluorescence in key marine creatureGreen fluorescent proteins were discovered in amphioxus, a fish-like animal found in coastal areas.
U.s. fires release large amounts of carbon dioxideLarge-scale fires in a western or southeastern state can pump as much carbon dioxide into the atmosphere in a few weeks as the state's entire motor vehicle traffic does in a year, according to newly published research by scientists at the National Center for Atmospheric Research (NCAR) and the University of Colorado at Boulder.
Yellowstone risingThe Yellowstone "supervolcano" rose at a record rate since mid-2004, likely because a Los Angeles-sized, pancake-shaped blob of molten rock was injected 6 miles beneath the slumbering giant, University of Utah scientists report in the journal Science.
Climate change could diminish drinking water more than expectedAs sea levels rise, coastal communities could lose up to 50 percent more of their fresh water supplies than previously thought, according to a new study from Ohio State University.
Like it or not, uncertainty and climate change go hand in hand
Despite decades of ever more-exacting science projecting Earth's warming climate, there remains large uncertainty about just how much warming will actually occur.
Why do autumn leaves bother to turn red?
Soils may dictate the array of fall colors as much as the trees rooted in them, according to a forest survey out of North Carolina.
Researchers find origin of breathable atmosphere half a billion years agoOhio State University geologists and their colleagues have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today.
