WASHINGTON (Reuters) – A fossil site in the Canadian Rockies that provides a wondrous peek into life on Earth more than half a billion years ago has offered up the remains of an intriguing sea creature, a four-eyed arthropod predator that wielded a pair of spiky claws.
Scientists said on Friday they unearthed nicely preserved fossils in British Columbia of the 508 million-year-old animal, named Yawunik kootenayi, that looked like a big shrimp with a bad attitude and was one of the largest predators of its time.
WASHINGTON (Reuters) – Satellite data from 1994 to 2012 reveals an accelerating decline in Antarctica’s massive floating ice shelves, with some shrinking 18 percent, in a development that could hasten the rise in global sea levels, scientists say.
The findings, published on Thursday in the journal Science, come amid concern among many scientists about the effects of global climate change on Earth’s vast, remote polar regions.
WASHINGTON (Reuters) – There is no sign the Ebola virus is mutating in an accelerated way that could make it more virulent or thwart vaccines or drugs under development despite some earlier fears to the contrary, researchers said on Thursday.
Earlier analyses had suggested to some experts that the virus might have been mutating at twice the rate observed in previous outbreaks, raising fears it could become even deadlier.
WASHINGTON (Reuters) – In a fresh rebuke to Benjamin Netanyahu, President Barack Obama said the Israeli leader’s pre-election disavowal of a two-state solution to the Israeli-Palestinian conflict makes it “hard to find a path” toward serious negotiations to resolve the issue.
In an interview with the Huffington Post, Obama also scolded Netanyahu over his remarks about Arab Israelis voting, making clear that the deep rift in relations between Israel and the United States, its most important ally, is not ending anytime soon.
WASHINGTON (Reuters) – President Barack Obama on Friday accused the Republican-led U.S. Senate of holding Loretta Lynch, his nominee for U.S. attorney general, as a “hostage” as lawmakers wrangle over a human trafficking bill bogged down in an abortion dispute.
Obama nominated Lynch, the Brooklyn federal prosecutor, in November to replace the retiring Eric Holder as the nation’s top law enforcement official. If confirmed by the Senate, she would become the first black woman to serve in the post.
WASHINGTON (Reuters) – The Obama administration moved on Friday to shore up management of the scandal-hit U.S. Secret Service, the agency charged with protecting the president, by filling the vacant deputy director job and creating a new senior administrative post.
The moves announced by Homeland Security Secretary Jeh Johnson and Secret Service Director Joseph Clancy come as the agency has staggered through a series of controversies involving worrisome security lapses and the conduct of individual agents.
WASHINGTON (Reuters) – The “Carolina butcher” has been found and is just as scary as the name suggests.
Scientists on Thursday said they had unearthed fossils in North Carolina of a big land-dwelling croc that lived about 231 million years ago, walked on its hind legs and was a top land predator right before the first dinosaurs appeared.
WASHINGTON (Reuters) – If you think you see a glowing mushroom, you might not be having a psychedelic hallucination. Some mushrooms indeed are bioluminescent, including one that sprouts among decaying leaves at the base of young palm trees in Brazilian coconut forests.
Scientists have long wondered what possible reason there could be for a fungus to glow. They now have an answer.
WASHINGTON (Reuters) – To 19th century British naturalist Charles Darwin, they were the strangest animals yet discovered, one looking like a hybrid of a hippo, rhino and rodent and another resembling a humpless camel with an elephant’s trunk.
Ever since Darwin first collected their fossils about 180 years ago, scientists had been baffled about where these odd South American beasts that went extinct just 10,000 years ago fit on the mammal family tree. The mystery has now been solved.
WASHINGTON (Reuters) – People adapted to living in tropical rainforests thousands of years earlier than previously known, according to scientists who found crucial evidence in 20,000-year-old fossilized human teeth discovered in Sri Lanka.
The researchers said there has been a debate over when our species first began living in rainforests, with some experts arguing such habitats may have been too daunting for early human hunter-gathers.
