Earth’s Core Hotter Than Thought, Hot As Sun’s Surface
PARIS (UPI) — New measurements suggest the Earth’s inner core is far hotter than previously thought, at 10,8000 degrees F as hot as the sun’s surface, French scientists say. The Earth’s core is solid, a crystalline form of iron, but the temperature at which that crystal can form has long been debated. New experiments used […]
Study: Being Alone Makes Danger Appear Closer Than When In A Group
EAST LANSING, Mich. (UPI) — Humans when alone see threats as closer than they actually are but in a close group that misperception disappears, Michigan State University researchers say. Their study is evidence people’s visual biases change when surrounded by members of their own group, creating a perception of “safety in numbers,” they said. “Having […]
When Looking For Something Lost, Brain Becomes ‘Search Engine’
BERKELEY, Calif. (UPI) — When searching for a lost item, animal or person, various regions of the human brain will switch from other tasks to join in the search, U.S. researchers say. For example, they said, if a person is looking for a child lost in a crowd, some brain areas usually dedicated to recognizing […]
Earth’s Pollinating Insects Face Risks That Threaten World Food Supply
LONDON (UPI) — Pollinating insects, vital to global food supplies, face a “cocktail” of multiple pressures putting their survival at risk, a British-led study indicated. Insects provide pollination activities to about 75 percent of the world’s crop species and their decline or loss could have profound environmental, human health and economic consequences, Britain’s Center for […]
China Tops List Of Sources Of Cyber-Espionage Attacks In 2012
NEW YORK (UPI) — China was the main source of cyber-espionage attacks in 2012, with Chinese IP addresses accounting for 30 percent of data breaches worldwide, a report says.

While existing systems that evaluate pitchers’ throwing motions require cameras and other sophisticated equipment and generally are confined to indoor use, the new system can be used on the field […]
Giant Panda Habitats Mostly Spared In Deadly China Earthquake
PMYA’AN, China (UPI) — The 7.0-magnitude earthquake that shook China’s Sichuan Province Saturday has had only limited effects on the region’s giant panda habitats, officials said.

DNA Study Suggests Human Immunity To Disease Has Ethnicity Basis
BURNABY, British Columbia, (UPI) — Immunity to disease may vary depending on ethnicity so designing treatments that will work for everybody may be impossible, U.S. and Canadian researchers say. DNA sequencing suggests human antibody genes and how well they operate — and what they can fight off — can vary from person to person, and […]
