Ancient China Skeletons To Yield DNA Data

ZHANGJIAKOU, China, (UPI) — Chinese scientists report they’ve launched a DNA test program on 22 human skeletons that date back more than 2,000 years. With the data, the scientists can analyze the diets, lifestyle habits and ages of the people living in the Warring States Period, 476-221 B.C., as well as the agriculture and business […]

Arctic Waters Rich In Marine Plants

WASHINGTON (UPI) — U.S. scientists say they’ve found ocean waters in the arctic richer in microscopic marine plants essential to all sea life than any other ocean region on Earth. The findings by NASA-sponsored expeditions in the summers of 2010 and 2011 reveal a new consequence of the arctic’s warming climate and provide an important […]

Eagles On Decline In Britain For Centuries

LONDON (UPI) — Golden and sea eagle populations have been declining in the British Isles for 1,500 years because of human activity, a report released Friday said. The report in the journal Bird Study blamed habitat loss and killing by humans for the decline, The Scotsman reported. Researchers believe there were between 1,000 and 1,500 […]

Parasites Spreading Virus In Bee Colonies

HONOLULU (UPI) — U.S. and British researchers say a parasitic mite is responsible for a worldwide spread of a virus believed to cause the death of millions of honeybee colonies. Research conducted in Hawaii by scientists from the University of Hawaii and Britain’s Sheffield University showed how Varroa mites caused the so-called Deformed Wing Virus […]

U.S. Has Warmest Spring Season On Record

WASHINGTON (UPI) — The United States had the second warmest May and the warmest spring on record, the National Oceanographic and Atmospheric Administration says. NOAA scientists said the average temperature for the contiguous 48 U.S. states during May was 64.3 degrees Fahrenheit, 3.3 degrees above the long-term average, making it the second warmest May on […]

Shrimp's Weapon Could Inspire Better Armor

RIVERSIDE, Calif. (UPI) — The unique structure of a club-like arm of a crustacean could inspire changes in military body armor and vehicle and aircraft frames, U.S. scientists say. The bright orange fist-like club of the mantis shrimp, a 4-inch-long crustacean found in tropical waters, accelerates underwater faster than a .22-caliber bullet and can smash […]

Colorado Wildfires Create Control Debate

DENVER (UPI) — A decade-long strategy of prescribed fires and forest-thinning has not reduced risks of catastrophic wildfires along Colorado’s Front Range, authorities say. There is increasing pressure to let more forests burn, if people and structures aren’t threatened, because this can help prevent huge fires that ruin forest seed stocks and watersheds, officials said. […]

U.S. Science, Engineering Enrollment Up

WASHINGTON (UPI) — U.S. graduate enrollment in science and engineering showed substantial growth in the last decade, a report by the National Science Foundation says. Approximately 632,700 graduate students were enrolled in science, engineering and health programs in the United States as of fall 2010, a 30 percent increase from 493,000 students in 2000, the […]

Report: U.S. Homes At Storm Surge Risk

SANTA ANA, Calif. (UPI) — Four million homes on U.S. Atlantic and Gulf coasts are at risk of hurricane storm-surge damage with more than $700 billion in property exposure, a report says. The report by CoreLogic said in the Atlantic Coast region alone there are approximately 2.2 million homes at risk, valued at more than […]

California Budget Would Cut Science Teaching

SACRAMENTO (UPI) — A second year of science would no longer be required for high school graduation under a California state budget proposal aimed at saving money, officials said. Educators have expressed concerns such a development could deepen the academic divide among students and further erode the state’s scientific and technological leadership. The proposal in […]
