Extinction: Humans played big role in demise of the cave bear

Science
The arrival of human ancestors in Europe some 40,000 years ago coincided with the downfall of the cave bear, scientists have revealed.New evidence suggests humans hunted the bear and drove it from caves, putting it on the road to extinction.The fate of the species was sealed by other pressures, such as the onset of the last Ice Age, and shrinking food resources.The bear eventually died out 24,000 years ago."We see this dramatic drop in the population of the cave bear starting from 40,000 years ago, which coincides with the arrival of anatomically modern humans in Europe," said Prof Verena Schuenemann of the University of Zurich, who led the study."It is the clearest evidence we have so far that humans might have played a big role...

Early humans may have crossed Central Asian deserts during wetter conditions

Science
May 30 (UPI) -- New research suggests northern and central Asia may have hosted early human migrations between 50,000 and 30,000 years ago. During the Late Pleistocene, early humans began spreading out across Eurasia. Previously, archaeologists and paleoanthropologists assumed pathways across northern and central Asia were blocked by mountains and deserts. As a result, most research efforts have focused on a southern migration route along the Indian Ocean. New research, however, suggests climate variation made northern and central Asia accessible to humans for brief periods of times. "Archaeological discussions of the migration routes of Pleistocene Homo sapiens have often focused on a 'coastal' route from Africa to Australia, skirting around India and Southeast Asia," Michael Petraglia,...

Smart speaker recordings reviewed by humans

Technology
Amazon, Apple and Google all employ staff who listen to customer voice recordings from their smart speakers and voice assistant apps.News site Bloomberg highlighted the topic after speaking to Amazon staff who "reviewed" Alexa recordings.All three companies say voice recordings are occasionally reviewed to improve speech recognition. But the reaction to the Bloomberg article suggests many customers are unaware that humans may be listening.The news site said it had spoken to seven people who reviewed audio from Amazon Echo smart speakers and the Alexa service.Reviewers typically transcribed and annotated voice clips to help improve Amazon's speech recognition systems.Amazon's voice recordings are associated with an account number, the customer's first name...
Humans can be tricked just like computers

Humans can be tricked just like computers

Science
March 22 (UPI) -- Using the same visual tricks that trip up computers, researchers at Johns Hopkins University have managed to get humans to think like CPUs. "Most of the time, research in our field is about getting computers to think like people," Chaz Firestone, an assistant professor of psychological and brain sciences at Johns Hopkins, said in a news release. "Our project does the opposite -- we're asking whether people can think like computers." Computers do a few things much better than humans. They can easily solve complex math problems and remember vast quantities of information. But some tasks that are quite easy for humans, recognizing everyday objects like a dog, bus or a table and chairs, are exceedingly difficult for even the most powerful computers. However, computers are g...

SpaceX capsule built for humans lands in Atlantic after space station stay

Technology
The unmanned Dragon capsule from Elon Musk's SpaceX has splashed down after a short stay at the International Space Station.It is the first time a commercial space system built for humans has been successfully flight tested by NASA. The capsule - containing a dummy called Ripley - reached hypersonic speeds after detaching from the ISS and splashed down off Florida at 8.45am local time. Its descent was slowed by four parachutes and recovery boats raced to intercept it about 200 miles off the Atlantic coast.Benjamin Reed, SpaceX's director of crew mission management, said: "Everything happened just perfectly, right on time the way that we expected it to." Dragon launched from Kennedy Space Center on a rocket last Saturday, in a major step towards reviving America's human spacefligh...
