“That’s one small step for man. One giant leap for mankind.” That famous communique from Apollo 11 during the historic first-ever moon walk was brought to you by the 64-meter antenna at NASA’s Deep Space Network in Goldstone, Calif.
Rodeo athletes have often been called a breed of their own and now University of Alberta research looking into how they deal with whiplash injuries confirms it.
The less a child sleeps, the more likely he or she is to become overweight, according to researchers from Université Laval’s Faculty of Medicine in an article published in the latest edition of the International Journal of Obesity. The risk of becoming overweight is 3.5 times higher in children who get less sleep than in those who sleep a lot, according to researchers Jean-Philippe Chaput, Marc Brunet, and Angelo Tremblay.
When men and women are angry, they both choose the news media articles they read with the goal of regulating their moods, a new study suggests. But, in some circumstances, men choose to read articles that will fuel their anger, while women choose articles that will dissipate it.
A jet fuel comparable to Jet A or military JP 8, but derived from at least 50 percent bituminous coal, has successfully powered a helicopter jet engine, according to a Penn State fuel scientist.
Frequent users of tanning beds may be getting more out of the experience than darker skin, according to researchers from Wake Forest University Baptist Medical Center. New evidence suggests that ultraviolet light has “feel-good” effects that may be similar to those of some addictive drugs.
North America isn’t the only continent that’s experienced super-colossal volcanic eruptions in the recent geologic past. The massive explosion of the almost unknown Vilama Caldera in Argentina appears to have matched Yellowstone’s last continent-blanketing blast. It may, in fact, be just one of several unappreciated supervolcanoes hidden in a veritable mega-volcano nursery called the Eduardo Avaroa Caldera Complex, located in the inhospitable Puna-Altiplano region near the tri-section of Argentina, Bolivia, and Chile.
So you don’t like eating peas? Then how about fueling your car or truck with them? That’s a possibility Agricultural Research Service scientists are exploring–using a type of fuel called ethanol, made from the legume’s starch.
The prospect of communicating with intelligent life beyond Earth has long captured human imagination. For decades, scientists have been patiently scanning the skies for radio waves or other signs that someone, somewhere, is sending missives into space. But we can send as well as receive, and it might be more efficient to send large messages across space not in the form of radio waves or beams of light, but in physical packages.
It’s not easy to see a total solar eclipse. They’re rare — the next one visible in the U.S. is in 2017 — and you can’t look directly at them. But in the early morning hours of March 29, seeing the next solar eclipse will be easy — just visit this Web page.
Loneliness is a major risk factor in increasing blood pressure in older Americans, and could increase the risk of death from stroke and heart disease, new research at the University of Chicago shows. Scholars found that lonely people have blood pressure readings that are as much as 30 points higher than in non-lonely people, even when other factors such as depressive symptoms or perceived stress are taken into account.
NASA senior management announced a decision Monday to reinstate the Dawn mission, a robotic exploration of two major asteroids. Dawn had been canceled because of technical problems and cost overruns.
Government policies in Burma that restrict public health and humanitarian aid have created an environment where AIDS, drug-resistant tuberculosis, malaria and bird flu (H5N1) are spreading unchecked, according to a report by researchers at the Johns Hopkins Bloomberg School of Public Health.
European researchers have created an interface between mammalian neurons and silicon chips. The development is a crucial first step in the development of advanced technologies that combine silicon circuits with a mammal’s nervous system.
A new discovery has found that Pin1, an enzyme previously shown to prevent the formation of the tangle-like lesions found in the brains of Alzheimer’s disease patients, also plays a pivotal role in guarding against the development of amyloid peptide plaques, the second brain lesion that characterizes Alzheimer’s.
Scientists at the U.S. Geological Survey (USGS) have found evidence in eastern North America that the snow is melting and running off into rivers earlier than it did in the first half of the 20th century. According to a USGS study published in the most recent issue of Geophysical Research Letters, winter-spring flows in many rivers in the northern United States and Canada are occurring earlier by 5-10 days.
A light-sensitive, self-assembled monolayer that provides unique control over particle interactions has been developed by scientists at the University of Illinois at Urbana-Champaign. Particles coated with the monolayer change their surface charge and chemistry upon exposure to ultraviolet light.
Join NOVA for an exclusive backstage pass to the DARPA Grand Challenge — a raucous race for robotic, driverless vehicles sponsored by the Pentagon, which awards a $2 million purse to the winning team. Armed with artificial intelligence, laser-guided vision, GPS navigation, and 3-D mapping systems, the contenders are some of the world’s most advanced robots. Yet even their formidable technology and mechanical prowess may not be enough to overcome the grueling 130-mile course through Nevada’s desert terrain.
