Green tea and red wine extracts interrupt Alzheimer's disease pathway in cells Posted: 05 Feb 2013 05:02 PM PST Natural chemicals found in green tea and red wine may disrupt a key step of the Alzheimer's disease pathway, according to new research.

Tourists face health risks from contact with captive sea turtles Posted: 05 Feb 2013 05:02 PM PST Tourists coming into contact with sea turtles at holiday attractions face a risk of health problems, according to new research.

Insect drives robot to track down smells Posted: 05 Feb 2013 05:01 PM PST A small, two-wheeled robot has been driven by a male silkmoth to track down the sex pheromone usually given off by a female mate. The robot has been used to characterize the silkmoth's tracking behaviors and it is hoped that these can be applied to other autonomous robots so they can track down smells, and the subsequent sources, of environmental spills and leaks when fitted with highly sensitive sensors.

Plants cut the mustard for basic discoveries in metabolism Posted: 05 Feb 2013 02:36 PM PST You might think you have nothing in common with mustard except hotdogs. Yet based on research in a plant from the mustard family, scientists have discovered a possible explanation for how organisms, including humans, directly regulate chemical reactions that quickly adjust the growth of organs. These findings overturn conventional views of how different body parts coordinate their growth, shedding light on the development of more productive plants and new therapies for metabolic diseases.

Water purification on the cheap: System cleans 'produced water' from natural gas wells Posted: 05 Feb 2013 10:17 AM PST A new system cleans 'produced water' from natural gas wells, and could lead to improved desalination plants for developing countries.

Newly discovered plant structure may lead to improved biofuel processing Posted: 05 Feb 2013 09:36 AM PST When a botanist approached his colleagues with some unusual data he had collected, they initially seemed convinced that his experiment had become contaminated; what he was seeing simply didn't make any sense.

Evidence moles can smell in stereo Posted: 05 Feb 2013 09:30 AM PST Neuroscientists have performed a series of tests that shows definitively that the common mole uses stereo sniffing to locate its prey.

Dinosaur footprints at NASA Goddard take another step Posted: 05 Feb 2013 09:29 AM PST A grouping of 110 to 112 million-year-old dinosaur footprints pressed into mud from the Cretaceous Period have now been safely moved from their original setting on the grounds of NASA's Goddard Space Flight Center in Greenbelt, Md. Until further scientific study is possible, the footprints, now wrapped in protective material, will be stored on the Goddard campus.

Fault lines in views on climate change revealed: Divided by cause, united by effect Posted: 05 Feb 2013 07:21 AM PST Climate change is a hotly debated issue, but a new study shows geoscientists and engineers also become embroiled in the issue -- and for some, it can get surprisingly personal. Younger, female engineers employed in government seemed to support the Kyoto Protocol, whereas their older, male counterparts -- largely employed by oil and gas companies -- tended to take a fatalistic response to climate change, labeling nature as the culprit.

Caring for dogs to reduce spread of parasite eggs harmful to humans Posted: 05 Feb 2013 07:21 AM PST New research has shown that dogs act as a major source of the parasite egg, Toxocara, which can potentially contaminate the public environment and infect humans.

Klondike, puppy born from a frozen embryo, fetches good news for endangered animals Posted: 05 Feb 2013 07:11 AM PST Meet Klondike, the western hemisphere's first puppy born from a frozen embryo. He's a beagle-Labrador retriever mix, and although neither of those breeds are endangered, Klondike's very existence is exciting news for endangered canids, like the red wolf.

Blowing hot and cold: U.S. belief in climate change shifts with weather Posted: 05 Feb 2013 05:30 AM PST A study of American attitudes toward climate change finds that local weather -- temperature, in particular -- is a major influence on public and media opinions on the reality of global warming.

Birds in Asia may need a hand to weather climate change Posted: 04 Feb 2013 07:08 PM PST Birds in Asia may need a helping hand to adapt to climate change, according to scientists. A new study shows that many bird species are likely to suffer under future climate change, and will require enhanced protection of important sites, better management of the wider countryside, and in some of the most extreme cases may need to be physically moved to climatically suitable areas to help them survive.

Could the humble sea urchin hold the key to carbon capture? Posted: 04 Feb 2013 07:08 PM PST The discovery that sea urchins use nickel particles to harness carbon dioxide from the sea could be the key to capturing tons of carbon dioxide from the atmosphere. Experts have discovered that in the presence of a nickel catalyst, carbon dioxide can be converted rapidly and cheaply into the harmless, solid mineral, calcium carbonate.

Hoodoos: Key to earthquakes? Posted: 04 Feb 2013 12:37 PM PST In the absence of long-term instrumental data, fragile rock formations, called hoodoos, may be key to understanding seismic hazard risk. In a new study, researchers consider two hoodoos in Red Rock Canyon region to put limits on expected intensity of ground motion from earthquakes along the Garlock fault.
