Study: Prehistoric Artists Were Children
ROUFFIGNAC, France, Oct. 3 (UPI) — Children, some as young as 3 years old, created prehistoric etchings found in a cave in France, researchers say. The so-called finger flutings, made by hands run along the cave’s soft surfaces, were discovered at the Cave of a Hundred Mammoths in Rouffignac, alongside cave art dating back about […]
Study: Some Learn Better From Mistakes
EAST LANSING, Mich., Oct. 3 (UPI) — People who think they can learn from their mistakes have a different brain reaction to errors than those who don’t think they can, U.S. researchers say. The study by Michigan State University researchers suggests a fundamental, hard-wired difference between these two groups, a university release reported Monday. “This […]
Evidence Found Of Ancient Huge Landslide
TENERIFE, Canary Islands, Oct. 3 (UPI) — One of the world’s best-preserved examples of a giant landslide from a volcanic eruption has been discovered in the Canary Islands, British researchers say. The southeast slopes of Tenerife Island collapsed into the sea during a huge volcanic eruption 733,000 years ago and the onshore remains of the […]
Cellphone Becomes Medical Image Device
DAVIS, Calif., Oct. 3 (UPI) — U.S. researchers say they’ve transformed an iPhone into a high-quality medical imaging device that could transform medicine in developing countries. Using only inexpensive materials, researchers at the University of California, Davis, have modified smartphones to perform detailed microscopy, a release from the Optical Society of America said Monday. Kaiqin […]
Largest Telescope Captures First Images
SAN PEDRO DE ATACAMA, Chile, Oct. 3 (UPI) — The largest, most complex telescope ever built, high on a plateau in Chile, has begun its search for evidence of how the universe began, astronomers said. The Atacama large millimeter/submillimeter array, or Alma, will seek to study processes occurring just a few hundred million years after […]
Study: Mosquitoes Find Human Breath, Odor
RIVERSIDE, Calif., Sept. 30 (UPI) — U.S. scientists say they’ve studied the flight paths of disease-carrying mosquitoes to find out how they locate and zero in on human target hosts. University of California, Riverside, entomologists say the carbon dioxide we exhale and the odors of our skin serve as crucial cues to female mosquitoes on […]
Researchers Hope To Predict 'Red Tides'
LOS ANGELES, Sept. 30 (UPI) — University of Southern California researchers say they’ve developed a new algae monitoring method that could help predict toxic phenomena known as red tides. Prediction is important as toxic algal blooms that can increase the amount of harmful toxins in the shellfish that California residents consume are increasing in frequency […]
Inexpensive System Can Disinfect Water
WEST LAFAYETTE, Ind., Sept. 30 (UPI) — A new technology using UV light from sunlight can disinfect drinking water for large parts of the world’s population easily and cheaply, U.S. researchers say. A team of Purdue University researchers says the system, in which sunlight is captured by a parabolic reflector and focused onto a UV-transparent […]
Drone To Be Used To Forecast Hurricanes
MIAMI, Oct. 1 (UPI) — The National Hurricane Center will fly a small unmanned aircraft into hurricanes next year to improve tropical storm forecasting. The aircraft, called GALE, is shot into a storm where it gathers wind speed and other atmospheric data, the South Florida Sun Sentinel reported Friday. “It gives us a better understanding […]
Budget Battle Splits U.S. Scientists
WASHINGTON, Oct. 3 (UPI) — U.S. scientists are split over congressional threats to cut funding for the overdue and over-budget James Webb Space Telescope, observers say. Telescope advocates say eliminating funding for the Webb project would cripple the quest for knowledge about the origins of the universe, The Baltimore Sun reported Sunday. “The project is […]
