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

NFL defensive end Michael Bennett was indicted Friday in Houston on a charge of injury to the elderly in connection with an incident that occurred when he was a spectator at the 2017 Super Bowl, authorities said.The Harris County district attorney's office said Bennett rushed the field when the game ended to congratulate his brother Martellus Bennett, who played for the winning New England Patriots.Bennett was told to use a different field entrance, but he pushed through the security detail, which included a 66-year-old paraplegic woman in a wheelchair, Houston Police Chief Art Acevedo said at a news conference.The woman suffered a sprained shoulder in the Feb. 5, 2017, incident, Acevedo said."It's offensive to me that a man who's supposed to be an example, a professional athlete, thinks its OK to act like this," Acevedo said.Bennett's legal team does not have a comment at this time, Frank Perez, a member of the team, said Friday night. CNN reached out to Bennett for comment through his representative Doug Hendrickson but has not heard back.Harris County said the felony charge carries a penalty of up to 10 years in prison and a ,000 fine.Bennett was one of the most vocal NFL players in protesting the national anthem before games.He appeared on CNN and said he didn't understand why President Donald Trump would "stoop so low" as to say that NFL owners should fire players who protest.Bennett, 32, played with the Seattle Seahawks for five seasons and just signed a contract with the Philadelphia Eagles. He played high school football in Houston and college ball at Texas A&M University.Acevedo said Bennett's lawyer has been notified. The chief said Bennett has not been arrested yet but should turn himself into police as soon as possible.When asked why it took more than a year to file charges against Bennett, Acevedo said police had to prioritize more serious crimes. Also, Hurricane Harvey hit Houston in August, he noted.Acevedo said an officer at the game witnessed Bennett pushing the woman but decided to check on the elderly woman rather than immediately arrest Bennett, whom he recognized."We knew who the suspect was," Acevedo said. "We knew what he had done and we knew where to find him."The Philadelphia Eagles said in a statement Friday: "We are aware of the situation involving Michael Bennett and are in the process of gathering more information. Because this is an ongoing legal matter, we will have no further comment at this time."Last September, Bennett complained that police in Las Vegas unfairly singled him out, threatened him with a gun and detained him briefly after he attended a prizefight between Floyd Mayweather Jr. and Conor McGregor.Las Vegas authorities said officers were responding to a call of battery and assault with a gun that had turned into an active shooter situation and thought that Bennett might be involved. No charges were filed. 2920
