California Meteor Intrigues Scientists

MOUNTAIN VIEW, Calif. (UPI) — Fragments of a meteorite that landed in California last week are much more interesting because of their composition than first thought, scientists say. Meteorite hunters found fragments after the meteor was sighted streaking through the sky April 22 and exploding in a fireball. NASA and the SETI Institute in Mountain […]

Communication Towers Said Killing Birds

LOS ANGELES (UPI) — Communication towers in North America are responsible for the deaths of nearly 7 million migrating birds as they fly south, researchers say. The 84,000 communication towers that dot North America, some rising as high as 2,000 feet, are proving deadly to birds migrating from Canada and the United States to Central […]

New Jersey Teens Win Math Competition

NEW YORK (UPI) — Five New Jersey high school students have won scholarships in a competition in which math was used to solve a current U.S. transportation issue, officials said. The contest drew nearly 5,000 11th- and 12th-graders from the eastern United States who were asked to use mathematical modeling to determine the best regions […]

Saturn Moon Called Planet ‘Building Block’

PASADENA, Calif. (UPI) — A NASA space probe has shown that Phoebe, one of Saturn’s moons, has more planet-like qualities than previously thought, U.S. scientists say. Data from NASA’s Cassini mission and a computer model of the moon’s chemistry, geophysics and geology show Phoebe is a so-called planetesimal, or remnant planetary building block, the National […]

Caribbean Lizards Face Extinction Threat

UNIVERSITY PARK, Pa. (UPI) — Twenty-four new species of lizard were recently discovered in the Caribbean and almost half are already close to extinction, researchers say. A team led by Blair Hedges, a professor of biology at Penn State University, discovered and named the 24 species of lizards known as skinks, an article in the […]

Study: Brain Waves Changed By Game Playing

TORONTO (UPI) — Playing an action videogame, even for just a short time, causes differences in brain activity and improvements in visual attention, Canadian researchers say. Twenty-five subjects who had not previously played videogames, taking part in research at the University of Toronto, played a game for a total of 10 hours in 1- to […]

‘Cannibal’ Shrimp In U.S. Waters A Worry

WASHINGTON (UPI) — An invasion of giant “cannibal” shrimp into America’s east coast and gulf coast waters appears to be getting worse, U.S. governmental researchers say. Scientists from the U.S. Geological Survey and the National Oceanic and Atmospheric Administration reported Thursday sightings of massive Asian tiger shrimp, which can eat their smaller shrimp counterparts, were […]

Pigeons Have A ‘Compass’ In Their Brains

WACO, Texas (UPI) — Pigeons navigate by recording information about Earth’s magnetic field, using certain brain cells as a sort of biological compass, U.S. scientists say. The finding gives insight into how many birds can migrate thousands of miles, flying day and night, even when the sun or stars are obscured by clouds, the researchers […]

EIA: $6 More To Drive For Vacation

WASHINGTON (UPI) — Prices at the gasoline pump could reach record levels during the summer, suppressing consumer demand, the U.S. Energy Department said. The U.S. Energy Department’s Energy Information Administration expects gasoline consumption to reach an average of 8.8 million barrels per day by summer, the lowest level since 2001. Prices at the pump, meanwhile, […]

Human Impact On Reef Sharks Studied

MANOA, Hawaii (UPI) — U.S. scientists say they’ve completed a first large-scale estimate of reef shark losses in the Pacific Ocean — and the news for the predators is not good. Many shark populations have plummeted in the past three decades as a result of excessive harvesting for their fins, as an incidental catch of […]
