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

NEW DELHI (AP) — An Indian husband and wife who fell to their deaths from a popular overlook at Yosemite National Park in the western U.S. were apparently taking a selfie, the man's brother said Tuesday.Park rangers recovered the bodies of 29-year-old Vishnu Viswanath and 30-year-old Meenakshi Moorthy on Thursday about 800 feet (245 meters) below Taft Point, where visitors can walk to the edge of a vertigo-inducing granite ledge that doesn't have a railing.Viswanath, who Cisco India said was a software engineer at the company's San Jose, California, headquarters, and Moorthy had set up their tripod near the ledge on Tuesday evening, Viswanath's brother, Jishnu Viswanath, told The Associated Press.RELATED: 2 die after falling from overlook in Yosemite National ParkPark visitors the next morning saw the camera and alerted rangers, who "used high-powered binoculars to find them and used helicopters to airlift the bodies," he said.In an eerie coincidence, a man who had hiked to the same spot with his girlfriend captured pictures of Meenakshi prior to her fall, saying she accidentally appears in the background of two of their selfie photos.Sean Matteson said Meenakshi stood out from the crowd enjoying the sunset atop Taft Point last week because her hair was dyed bright pink and that she made him a little nervous because he felt she was standing too close to the edge.RELATED: Photographer finds mystery engagement couple in viral Yosemite photo"She was very close to the edge, but it looked like she was enjoying herself," said Matteson, who lives in Oakland, California. "She gave me the willies. There aren't any railings. I was not about to get that close to the edge. But she seemed comfortable. She didn't seem like she was in distress or anything."Matteson said Moorthy's pink-haired visage appears in the background of two photos he snapped of himself and his girlfriend Drea Rose Laguillo. He said Laguillo noticed that Moorthy had been captured in their images on Monday after pictures of the two victims were published.Matteson said he doesn't recall noticing Viswanath when he and his girlfriend were at the overlook with less than a dozen other tourists. The couple left the overlook as darkness was approaching, Matteson said.RELATED: More than 250 people around the world have died taking selfies since 2011The Indian couple's funeral will take place in the U.S. because the bodies were not in a condition to be flown back to India, Jishnu Viswanath said.The couple was "travel-obsessed," Moorthy wrote on a blog called "Holidays and HappilyEverAfters" filled with photos of them in front of snowy peaks, the Eiffel tower and tulip fields. Moorthy had wanted to work full time as a travel blogger, Viswanath said."A lot of us including yours truly is a fan of daredevilry attempts of standing at the edge of cliffs and skyscrapers, but did you know that wind gusts can be FATAL???" Moorthy wrote on an Instagram post with a photo of her sitting on the edge of the Grand Canyon. "Is our life just worth one photo?"RELATED: Teen dies after falling while taking selfie in Yosemite National ParkThe couple graduated in 2010 from the College of Engineering, Chengannur, in Alapuzha district of Kerala state, one of their professors, Dr. Nisha Kuruvilla, told AP.She said Moorthy and Viswanath were both good students who were fond of traveling and had married at a Hindu temple in Kerala in southern India four years ago.Yosemite spokeswoman Jamie Richards said in a statement that park officials were investigating the deaths and that the investigation could take several days.In India, after a rash of selfie-related deaths, the Tourism Ministry in April asked state government officials to safeguard tourists by installing signs in areas where accidents had occurred declaring them "no-selfie zones." 3853

North Korea appeared to destroy at least three nuclear tunnels, observation buildings, a metal foundry and living quarters at its Punggye-ri nuclear test site on Thursday, in a process observed by invited international journalists.A CNN crew at the remote mountain site in the country's north witnessed explosions at nuclear tunnels 2, 3 and 4, from observation decks about 500 meters away.They were among two dozen journalists invited into the country to observe the apparent destruction of the site, which comes just weeks before a planned meeting between North Korean leader Kim Jong Un and US President Donald Trump.The journalists spent about 10 hours on the ground at the nuclear test site before leaving by train for the 12-hour journey back to the North Korean coastal city of Wonsan.North Korea announced on April 20 that the country had "realized nuclear weaponization," and would no longer need to test nuclear weapons. To demonstrate its commitment, it said it would destroy the nuclear test site.North Korea said inviting international media to the event would "ensure transparency of discontinuance of the nuclear test."Before the explosions, the journalists said they were invited to look inside three of the four tunnels, which appeared to be rigged with explosives, before moving a safe distance away to witness their detonation.The amount and type of explosives used were not described by the regime. The CNN journalists present described seeing "soccer ball" sized and shaped explosives, rigged alongside one another, visible for a distance of around 35 meters inside the tunnels.The journalists watched a succession of explosions, and when they were finished were allowed closer to inspect the damage. Each tunnel was caved in, with rubble blocking the entrance.There were no international experts in the invited group and no one was present who was able to assess the explosions in order to tell if they were deep enough to destroy the tunnels.North Korea has conducted six nuclear tests at the site, which lies more than 200 miles (370 kilometers) north of Pyongyang, the most recent and powerful of which was in September 2017.There are four tunnels at the site, although journalists only witnessed the destruction of three. A fourth tunnel used for one nuclear test in 2006 had already been shut down, North Korean officials said. The journalists were also shown two additional tunnels that the North Korean officials said had never been used before.Before Thursday's explosions, experts had warned that the tunnels' destruction could destroy valuable evidence of the state of North Korea's weapons program. They told CNN they would want to take samples, as well as radiation counters to assess the levels in the atmosphere.Journalists who attempted to take radiation measuring equipment into North Korea said it had been confiscated.Tom Cheshire, a correspondent with Britain's Sky News, said his team's satellite phone and radiation dosimeter -- a device to measure nuclear radiation -- was taken away by security at Wonsan airport. Chinese journalists also had equipment confiscated.?The-CNN-Wire 3131

NEWTOWN, Connecticut — After 20 children and six adults died at Sandy Hook Elementary School nearly five years ago, the district promised to rebuild a school that looked nothing like the one where a shooter went on a rampage and the district promised the new school would be the most secure one in the country. 318
