New research may be hard for some dog owners to accept; the study found that dogs do not understand every word a human says to them.The researchers say dogs cannot hear subtle differences between words the way humans can. For example, the difference between “dog” and “dig” sounds different to human ears, but not so different to dog ears.The researchers came to their conclusion after measuring brain activity of family dogs by taping electrodes to the animals’ heads. They then played recordings of instruction words they knew, like “sit,” then similar-sounding nonsense words, like “sut,” and finally an unrelated nonsense word or sound, like “bep.”The dogs in the study, who were not trained ahead of the study, could quickly tell the difference between the instruction words and the unrelated nonsense words."The brain activity is different when they listen to the instructions, which they know, and to the very different nonsense words, which means that dogs recognize these words," lead study author and postdoctoral researcher at E?tv?s Loránd University in Budapest, Lilla Magyari told CNN.So, the good news is, yes, dogs are listening to human words and understanding some.However, brain activity showed a similar reaction in the dogs between the instruction word and the similar nonsense word.Dogs are renowned for their auditory capacity and ability to hear words and sounds, however the results show they may not be able to distinguish between subtle speech sound differences.Magyari says more research is needed to understand why this is."They may just not realize that all details, the speech sounds, are really important in human speech. If you think of a normal dog: That dog is able to learn only a few instructions in its life," she told CNN.The study was published this week in the Royal Society Open Science journal. 1845

NEWPORT BEACH, Calif. (AP) — Prosecutors added criminal charges involving five additional victims Wednesday in the case of a California surgeon and his girlfriend who were previously charged with drugging and sexually assaulting two women.The Orange County district attorney's office said the additional charges include kidnapping and rape by use of drugs.The new charges accuse Dr. Grant Robicheaux of sexually assaulting five additional women. His girlfriend, Cerissa Riley, is now charged in three additional assaults. Details were not immediately released.Robicheaux, 38, and Riley, 31, appeared in court and pleaded not guilty to all counts. A judge ordered their bail to be raised to million each, up from 0,000 each.Robicheaux once appeared in a reality TV show called "Online Dating Rituals of the American Male."When the pair was originally charged last month, prosecutors said they received leads to more than a dozen possible additional victims.Authorities said the two initial victims met Robicheaux and Riley at social events in Southern California, where they became intoxicated and ended up at Robicheaux's apartment.Robicheaux could now face a term of more than 82 years to life in prison if convicted. Riley could face 63 years to life in prison if convicted.Both had friends and family who walked up and hugged them during a break in the courtroom proceedings. During a bail discussion, Riley turned to see them in the gallery and fought back tears. Afterward, she cried in the courtroom while being hugged by supporters."Thanks for coming," she said.___Associated Press reporter John Antczak contributed to this report from Los Angeles. 1669

New security measures were enforced as students of Santa Fe High School in Texas returned for the new school year Monday.The security changes come after a student opened fire on May 18, killing 10 students.The most noticeable security addition: metal detectors. Other renovations at the high school include the installation of bullet-proof glass, a secure entrance vestibule and even panic buttons in the classrooms. Interior doors were upgraded to lock from the inside and outside and 500 security cameras were installed district wide. Additionally, the school hired extra police offers, five of which will work fulltime.“Well, it's a very typical reaction from what we’ve seen in a lot of schools in the wake of spring of ’18,” says Amy Klinger.Klinger, a school safety expert with The Educator’s School Safety Network, says on one hand she’s glad to see more schools like Santa Fe investing in new measures, but she cautions money also needs to be spent on the teachers, too.“Are we combining buying stuff with actually training people?” asks Klinger. “Probably a single point of entry is a good idea, but not if you haven't provided people with training on how to screen visitors who are coming in.”Since teachers themselves are the first line of defense, The Educators School Safety Network is urging all schools to consider training faculty to better recognize out of ordinary behavior.“We know that anywhere between 80 to 85 percent of all perpetrators are students in that school, so who is working with those students? Educators,” says Klinger. “So, we need to invest in those people that see those kids every single day and to give them tools and resources and training to be able to pick up on students who are at risk.” 1739
