14,700 years ago, cannibals conducted rituals in this English cave

PLoS Nestled in the dramatic Cheddar Gorge in Somerset, UK, there’s a roomy limestone cave called Gough’s Cave where a few generations of people lived about 14,700 years ago. They littered the floor with the remnants of their meals, leaving hundreds of bones behind for archaeologists to find. Now, scientists have analyzed these bones and discovered that some of them are from six separate human beings. And they bear the distinct marks of ritual cannibalism. Natural History Museum of London scientist Silvia Bello and her colleagues write in PLoS One about the find. The bones came from a child, two adolescents, two adults, and one elderly adult. All showed evidence of butchery, which leaves characteristic marks behind when sharp tools are used for defleshing. The bones were also covered in human tooth marks from biting and gnawing, and some had been broken open for their marrow. Read 10 remaining paragraphs | Comments

Apollo astronauts dying of heart disease at 4-5X the rate of counterparts

(credit: NASA ) Deep space travel takes a toll on the body—and it’s apparently something you can’t moon-walk off. Apollo astronauts who have ventured out of the protective magnetosphere of mother Earth appear to be dying of cardiovascular disease at a far higher rate than their counterparts—both those that have stayed grounded and those that only flew in the shielding embrace of low Earth orbit. Though the data is slim—based on only 77 astronauts total—researchers speculate that potent ionizing radiation in deep space may be to blame. That hypothesis was backed up in follow-up mouse studies which provided evidence that similar radiation exposure led to long-lasting damage to the rodents’ blood vessels. All of the data is published Thursday in the journal Scientific Reports . The study, while not definitive, may add an extra note of caution to the potential hazards of future attempts to fly to Mars and elsewhere in the cosmos. Read 9 remaining paragraphs | Comments

Marriott removing desks from its hotel rooms "because Millennials"

Yahoo sport columnist Dan Wetzel checked into a Marriott, something he does a lot, and was bewildered to discover that his room didn’t have a desk. When he called down to the reception, he discovered that the whole chain was gradually removing its desks, because some consultants told them that Millennials like to chill on couches with their phones, not sit at desks like square-ass Old People.
