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.
Federal researchers next week will start testing humans with an experimental vaccine to prevent the deadly Ebola virus. The National Institutes of Health announced that it is launching the safety trial on a vaccine developed by the agency's National Institute of Allergy and Infectious Diseases and GlaxoSmithKline.
A senior federal nuclear expert is urging regulators to shut down California's last operating nuclear plant until they can determine whether the facility's twin reactors can withstand powerful shaking from any one of several nearby earthquake faults.
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.
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 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.
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.
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.
Biologists studying fruit flies have identified a mechanism that helps explain how the diversity of neurons that make up the visual system is generated.
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.
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 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.
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.
A number of leading international researchers have recommended that fluorochemicals are only used where they are absolutely essential, until better methods exist to measure the chemicals and more is known about their potentially harmful effects.
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.
