Large predators are showing up in surprising places

Science
May 7 (UPI) -- Large predators are increasingly being spotted in places they're not traditionally found: killer whales in rivers, alligators on beaches and cougars far from the mountains.It's been suggested hunger and lack of prey have pushed predators into strange habitats, but new research suggests these species are recolonizing habitats they've lived and hunted in for centuries -- before they were pushed to the brink of extinction by humans.Finding large predators in new places isn't a sign of desperation, researchers argue, but evidence of rebounding populations."We can no longer chalk up a large alligator on a beach or coral reef as an aberrant sighting," Brian Silliman, a professor of marine conservation biology at Duke University's Nicholas School of the Environment, said in a news ...

Arctic permafrost home to large mercury reserves, study finds

Science
Feb. 5 (UPI) -- Scientists have discovered large mercury reserves trapped in Arctic permafrost.According to a new study published in the journal Geophysical Research Letters, the mercury reserves are the largest in the world."This discovery is a game-changer," lead study author Paul Schuster, a hydrologist at the U.S. Geological Survey in Boulder, Colorado, said in a news release. "We've quantified a pool of mercury that had not been done previously, and the results have profound implications for better understanding the global mercury cycle."The monumental mercury levels were revealed by permafrost cores drilled in northern Alaska. Analysis suggests the Arctic permafrost holds double the amount of Mercury found in all the rest of the planet's ocean, sediment and atmospheric systems combin...

Landscaper charged with killing 5 allegedly hid some remains in large planters: Cops

World
A landscaper described by Toronto police as an alleged serial killer is accused of hiding some dismembered remains in the bottom of large planters, authorities said. Bruce McArthur was charged this month with the deaths of five men, Toronto police said, adding that there could be even more victims. Police say the dismembered remains of at least three people have been found hidden in the bottom of large planters in the backyard of a home McArthur allegedly used for storage. Those remains have not yet been identified. Police are conducting searches at 30 properties where McArthur worked and said more remains could be discovered. Over a dozen planters have been recovered from various addresses, Toronto Police Sgt. Hank Idsinga said. "We do believe there are more" victims, Idsinga said at...
Pollution particles fuel large storms, research shows

Pollution particles fuel large storms, research shows

Science
Jan. 26 (UPI) -- New research suggests scientists have underestimated the importance of particulate matter as a driver of storm size and intensity.Scientists have previously proven that aerosols, particles suspended in the atmosphere, can influence weather and climate. With their latest study -- published this week in the journal Science -- researchers with the Department of Energy's Pacific Northwest National Laboratory showed the smallest particles can encourage the formation and increase the intensity of storms."We showed that the presence of these particles is one reason why some storms become so strong and produce so much rain," PNNL researcher Jiwen Fan, lead author of the new study, said in a news release. "In a warm and humid area where atmospheric conditions are otherwise very cle...
