Study: Off-campus college party hosts drink more than attendees

On any given weekend, at least 10 percent of students at a single college could be hosting a party, and on average, party hosts who live off campus are drinking more and engaging in more alcohol-related problem behaviors than are the students attending their bashes, research suggests.

Addition of proton pump inhibitor to treatment of poorly controlled asthma in children does not improve symptoms

Children without symptoms of gastroesophageal reflux whose asthma was being poorly controlled with anti-inflammatory treatment did not have an improvement in symptoms or lung function with the added treatment of the proton pump inhibitor lansoprazole, compared to patients who received placebo, according to a new study. Use of lansoprazole was associated with increased adverse...

Lab mimics Jupiter's Trojan asteroids inside a single atom

Physicists have built an accurate model of part of the solar system inside a single atom. Scientists have shown that they could make an electron orbit the atomic nucleus in the same way that Jupiter's Trojan asteroids orbit the sun. The findings uphold a 1920 prediction by physicist Niels...

Ancient Dog Skull Offers Domestication Clues

A 33,000-year-old dog skull found in a Siberian cave is among the oldest evidence of dog domestication ever found, researchers say. Scientists at the University of Arizona say the discovery also suggests man's best friends may have originated from more than one ancient ancestor. They base that on dog remains of the same age found in a cave in Belgium. "Both the Belgian find and the...

Marine mammals on the menu in many parts of world

The fate of the world's great whale species commands global attention as a result of heated debate between pro and anti-whaling advocates, but the fate of smaller marine mammals is less understood, specifically because the deliberate and accidental catching and killing of dolphins, porpoises, manatees, and other warm-blooded aquatic species are rarely studied or...

Bilayer graphene works as an insulator: Research has potential applications in digital and infrared technologies

Physicists have identified a property of "bilayer graphene" that the researchers say is analogous to finding the Higgs boson in particle physics. The physicists found that when the number of electrons on the BLG sheet is close to 0, the material becomes insulating -- a finding that has implications for the use of graphene as an electronic material in the semiconductor and electronics...

A hint of frog in the air: Macrolides are volatile pheromones from Madagascar frogs

Amphibians are at home in water, but can they also sense volatile compounds in the air? “Indeed they can,” reports Stefan Schulz. Working with colleague Miguel Vences and Ph.D. students Dennis Poth and Katharina Wollenberg at the University of Brunswick, he has found volatile pheromones in frogs from Madagascar. In the journal Angewandte Chemie, the scientists have now introduced various...

Avoid the fallout: New ligands for nuclear waste treatment

(PhysOrg.com) -- Storage and containment of the "nuclear legacy", the highly radiotoxic residues from spent nuclear reactors is a pressing problem for the nuclear power industry that must be solved if nuclear power is to have a genuine contribution to providing carbon footprint minimised power. The search for new ways to lessen the environmental impact of such events is therefore of utmost...
