Humans are still evolving, study suggests

Sept. 5 (UPI) -- Some have suggested modern medicine has frozen human evolution. With advanced medicine and reproductive technologies, the vast majority of humans enjoy lifespans long enough to pass on their genes to the next generation.But a new study suggests natural selection is still altering the human genome in subtle ways. When researchers surveyed the genomes of 210,000 people from the United States and Britain, they found genetic anomalies linked to Alzheimer's disease and heavy smoking were less common among those with longer lifespans. Scientists also found those who lived longer were less likely to carry genetic mutations linked with heart disease, high cholesterol, obesity, and asthma.The findings -- detailed this week in the journal PLoS Biology -- suggest humans are still inf...

To teach kids morals, read books with humans not animals

Science
Aug. 18 (UPI) -- Anthropomorphic, or human-like, animals are often the protagonists of children's books. But new research suggests parents who want their kids to pick up on a story's moral lessons should choose books featuring humans, not animals.Researchers in Canada found four to six-year-olds were more likely to share with their peers after being read a story with human characters."Many people believe children find stories with human-like animals captivating and relatable, but what we're finding is that this is not the case," Dr. Patricia Ganea, associate professor of early cognitive development at the University of Toronto, said in a news release. "Overall, children were more likely to act on the moral of the story when it featured a human character."Researchers read stories about shar...

The one law of robotics: Humans must flourish

Technology
The science-fiction writer Isaac Asimov wrote about controlling intelligent machines with the three laws of robotics:A robot may not injure a human being or, through inaction, allow a human being to come to harmA robot must obey orders given to it by human beings except where such orders would conflict with the first lawA robot must protect its own existence as long as such protection does not conflict with the first or second lawAs so often is the case, science fiction has become science fact. A report published by the Royal Society and the British Academy suggests that there should not be three but just one overarching principle to govern the intelligent machines that we will soon be living alongside: "Humans should flourish."According to Prof Dame Ottoline Leyser, who co-chairs the Roya...
