May 14 (UPI) -- Some 30,000 years ago, in the midst of the Ice Age, cartoonish caricatures of animals gave way to more realistic art. New research suggests the shift in aesthetic could be explained by "detail focus," a trait linked to autism. Seemingly all at once, detailed depictions of bears, bison, horses and lions began to appear in significant numbers in Ice Age caves. Scientists have struggled to account for the sudden change. Researchers have previously suggested psychotropic substances inspired the explosion of detail-oriented drawings, but a new study discounts such an explanation. Instead, archaeologists at the University of York argue a trait linked with autism, called detail focus, jumpstarted the trend. "Detail focus is what determines whether you can draw realistically; you...

March 14 (UPI) -- Researchers at the Cleveland Clinic have developed a prosthetic arm with more natural movement sensation.With the new prosthetic, patients who had previously undergone targeted nerve reinnervation can direct amputated nerves to remaining muscles. They can "feel" their palm, back of the hand and even felt each finger, according to researchers.One test participant, 49-year-old-of Amanda Kitts of Bonita Springs, Fla., whose arm was amputated above the elbow in 2006 after a car accident, told UPI it was "amazing."She said Dr. Paul Marasco, who leads a research team at the Laboratory for Bionic Integration in Cleveland Clinic's Lerner Research Institute, has "made my life a better place." His research was published online Wednesday in Science."By restoring the intuitive feelin...

Internet speed guarantees must be realistic, says Ofcom

Internet users are to be granted more rights on connection speeds as Ofcom imposes tougher rules on how ISPs advertise broadband services.The proposals give consumers the right to exit contracts penalty-free if speeds fall below a guaranteed minimum.Ofcom says there is a mismatch between what is advertised, and the speeds customers receive.But experts say speeds are affected by different factors, and are not strictly a measure of connection to a device. A public consultation is currently being conducted until 10 November.Easy way outGillian Guy, chief executive of Citizens Advice, said: "Many people seek our help each year because their slow and intermittent broadband service falls short of what their contract promised."For most people, a reliable broadband connection is a necessity, so wh...
