Some cats may seem a little more aloof than dogs, but they respond to the people they've bonded with in a similar way, according to a new study.Research at Oregon State University has shown that cats can form secure or insecure bonds with their owners. The researchers now believe the trait isn't specific to dogs, as similar research has shown, since it now applies to cats.During human attachment behavior studies, researchers look at how babies respond when they're reunited with their parent or caregiver after a short absence. When they're reunited, securely bonded babies return to exploring their surroundings in a relaxed way. About 65% of babies have a secure attachment. But insecurely attached babies will either avoid their parent or cling to them.The same tests have been simulated with primates as well. After applying it to dogs, babies and primates, the researchers wanted to see what would happen when they added cats and kittens to the scenario.The cats and kittens would individually spend two minutes in a room with their owner or caregiver. Then, the person would leave the room for two minutes, followed by a two minute reunion. This is called a "secure base test."About 65% of the cats and kittens were found to be securely bonded to their owners. Their finding shows that the cats' bonds with people were stable in adulthood, and not just present in kittens.The securely attached cats will continue to explore their surroundings after their owner returned, as well as pay attention to their owner. The insecurely attached cats showed signs of stress, like twitching tails, licking lips, avoiding their owner or jumping in their lap and not moving, which is a sign of ambivalence.A study detailing the findings published Monday in the journal 1778

Sen. Jeff Merkley announced Tuesday that he is not running for President, telling supporters in a video that he will remain in the Senate after mulling a presidential bid for months.In a video that in many ways mimicked a presidential announcement, Merkley laid out his life story, described issues that he believes need to be tackled and outlined what could have been a rationale for a 2020 run. But the Oregon Democrat says in the video that he believes Democrats need leadership in the Oval Office and the Senate and that he believes he could be most effective in the legislative body."Over the last year, I've weighed whether I can contribute more to the battle by running for president or by running for reelection to the Senate," Merkley said. "Today, I am announcing that I am not running for president."Merkley did not endorse a candidate currently in the race and added, "I believe that there are Democrats now in the presidential race who are speaking to the importance of tackling the big challenges we face. But what I'm also sure of is that right now the Senate is not prepared to be a full partner in this fight."Instead of running for president, Merkley will now spend the next two years running for reelection in Oregon, a race that all nonpartisan handicappers rate as a seat safely in Democratic hands.Merkley, a Democrat representing Oregon since 2009, was the only US senator to endorse Bernie Sanders in the 2016 election over his rival, Hillary Clinton. Despite that support, Merkley said if Sanders was losing to Clinton after the primary season, he should end his presidential campaign and concede to Clinton.Merkley, a member of the Senate Foreign Relations Committee, has been a major critical voice of the Trump administration in the Senate, particularly its handling of immigration issues. In June, the senator made headlines when he was denied entry to a Texas immigration center for unaccompanied minors when he showed up and asked for a tour. He accused the administration of being part of a "cruel" effort against unauthorized immigrant children.In January he asked the FBI to open a perjury investigation into Homeland Security Secretary Kirstjen Nielsen. The call came a day after he released a draft memo that shows the Trump administration was drafting a policy as early as December 2017 to separate families apprehended at the US southern border. The administration has repeatedly denied there was a policy to separate families, and Merkley said Nielsen made the same claim when she testified before Congress.Late last year, Merkley told ABC that his family had given him a "thumbs-up" to run for President, and that he would make a decision within the first three months of 2019. 2729
