Global Warming Won't Stop Snowstorms

August 29, 2014 7:00 am | by MIT, Jennifer Chu | News | Comments

If ever there were a silver lining to global warming, it might be the prospect of milder winters. But, a new study suggests that you shouldn’t put your shovels away just yet. While most areas in the Northern Hemisphere will likely experience less snowfall throughout a season, the study concludes that extreme snow events will still occur, even in a future with significant warming.

Physicists See Neutrinos in Heart of Sun

August 29, 2014 7:00 am | by Univ. of Massachusetts Amherst | News | Comments

Using one of the most sensitive neutrino detectors on the planet, an international team of physicists are reporting that, for the first time, they have directly detected neutrinos created by the "keystone" proton-proton fusion process going on at the sun's core.

Old Tires Get a Second Chance in Batteries

August 28, 2014 2:00 pm | by Oak Ridge National Laboratory | News | Comments

Recycled tires could see new life in lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by wind and solar. By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a team is developing a better anode for lithium-ion batteries.

Researchers Purposefully Trip Senior Citizens

August 28, 2014 2:00 pm | by Associated Press | News | Comments

Researchers are tripping seniors on purpose, and it's not some kind of warped practical joke. The experiment is among techniques being studied to prevent falls, the leading cause of injury in older adults. Falls in the elderly cost $30 billion yearly to treat and can send them spiraling into poor health and disability.

WHO: Ebola Cases May Reach 20,000

August 28, 2014 2:00 pm | by Associated Press, John Heilprin, Krista Larson | News | Comments

The Ebola outbreak in West Africa eventually could exceed 20,000 cases, more than six times as many as doctors know about now, the World Health Organization said today. A new plan to stop Ebola by the UN health agency also assumes that in many hard-hit areas, the actual number of cases may be two to four times higher than is currently reported.

Feds OK Logging After Californian Wildfire

August 28, 2014 2:00 pm | by Associated Press, Scott Smith | News | Comments

U.S. Forest Service officials say they tried to balance competing interests in a plan released this week that allows loggers to remove trees killed in a massive central California wildfire last year, but environmentalists called it a travesty and threaten to sue.

‘Contaminated’ Blood Tests May Save Lives

August 28, 2014 2:00 pm | by American Friends of Tel Aviv Univ. | News | Comments

Some 30 percent of all positive hospital blood culture samples are discarded every day because they're contaminated— they reflect the presence of skin germs instead of specific disease-causing bacteria. But, rather than toss these compromised samples into the trash, clinicians may be able to use the resistance profiles of skin bacteria identified by these tests to treat patients with antibiotics appropriate to their ailment.

Study Charts Invasion of Crop Pests

August 28, 2014 2:00 pm | by Univ. of Exeter | News | Comments

More than one-in-10 pest types can already be found in around half the countries that grow their host crops. If this spread advances at its current rate, scientists fear that a significant proportion of global crop-producing countries will be overwhelmed by pests within the next 30 years.

Gamblers are Birdbrained

August 28, 2014 7:00 am | by Univ. of Warwick | News | Comments

Gamblers are greedy and birdbrained, new research has found. Gamblers show the same tendencies as pigeons when they make risky decisions. Tests have found that both human gamblers and pigeons were 35 percent more likely to gamble for high-value than low-value rewards.

Pebble-sized Particles May Jump-start Planet Formation

August 28, 2014 7:00 am | by National Radio Astronomy Observatory | News | Comments

Astronomers have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles— planetary building blocks 100 to 1,000 times larger than the dust grains typically found around protostars. If confirmed, these dense ribbons of rocky material may well represent a new, mid-size class of interstellar particles that could help jump-start planet formation.

Lethal Spears Indicate Early Cognitive, Social Skills

August 28, 2014 7:00 am | by Arizona State Univ. | News | Comments

Attaching a stone tip to a wooden spear shaft was a significant innovation for early modern humans living around 500,000 years ago. However, it was also a costly behavior in terms of time and effort to collect, prepare and assemble the spear. The skill was likely to have been passed from generation to generation through social or group learning.
