Did humans kill off cave lions for their pelts?
Some 16,000 years ago a big cat died. Today, its toes may provide insight into its species' extinction.The cave lion, Panthera spelaea, once roamed from Europe to northern North America. Scientists think the animal was much like its modern African counterpart and hunted large animals like deer and bison. But about 12,000 ago or so, cave lions vanished from the landscape. Scientists have suggested that changes in climate drove P. spelaea to extinction, but a study published Wednesday in the jour..>> view originalHow Warm Winters in the Arctic Make Colder Ones for You
Warm winters in the Arctic may contribute to colder winters in the United States and Europe, according to new research. The study, published in the journal Nature Climate Change, shows that the Arctic polar vortex—a large pressure system—has been shifting away from North America toward Europe over the past several decades. That in turn has allowed cold temperatures to seep downwards, making for frigid winters in North America and the United Kingdom while the Arctic experiences unprecedented w..>> view originalViral Facebook pages are passing off old space clips as live footage to millions of viewers
Facebook has been pushing live video as its next big format for a while now, and that means there are plenty of media outlets trying to take advantage of the extra visibility. Some, though, aren’t being so honest about it, with Mashable pointing out this week that some viral Facebook pages have been passing off archive footage from the International Space Station as live streams from off the planet. UNILAD and Viral USA are two pages that tricked viewers in this way, launching hours-long "live"..>> view originalNew Oil Discoveries Largely Unaffected by Paris Pact
New Oil Discoveries Largely Unaffected by Paris Pact Large crude oil discoveries in 2016 face uncertain prospects of development for many reasons, but climate change isn’t one of them, at least for the moment. Climate policies that help countries meet their obligations under the Paris Agreement are likely to have little effect on newly discovered oil fields because the Paris pact all but ignores crude oil consumption and production, experts say. The fate of new oil discoveries hinges mainly on ..>> view originalResearchers Clear 'Patient Zero' From AIDS Origin Story

A moderate geomagnetic storm in Earth's magnetic field created some luminous auroras as far south as the northern United States last night. Space weather refers to the stream of radiation and powerful particles ejected into space from the sun. The Earth is largely protected from space weather by the planet's atmosphere and its magnetic field. When solar material hits the magnetic field and causes a disturbance — or what's known as a geomagnetic storm, according to the National Oceanic and A..>> view originalWorld wildlife 'falls by 58% in 40 years'
