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
SpaceX completed the last big test of its crew capsule before launching astronauts in the next few months, mimicking an emergency escape shortly after liftoff Sunday.No one was aboard for the wild ride in the skies above Cape Canaveral, just two mannequins. The nine-minute flight ended with the Dragon crew capsule parachuting safely into the Atlantic, after separating and speeding away from the exploding rocket.“I’m super fired up,” Elon Musk, the company’s founder and chief executive, told reporters. “It’s just going to be wonderful to get astronauts back into orbit from American soil after almost a decade of not being able to do so. That’s just super exciting.”NASA astronauts have not launched from the U.S. since the space shuttle program ended in 2011. Musk and NASA Administrator Jim Bridenstine said the next Crew Dragon could launch with a pair of NASA astronauts in the second quarter of this year — as early as April.The Falcon 9 rocket blasted off as normal, but just over a minute into its supersonic flight, the Dragon crew capsule catapulted off the top 12 miles (20 kilometers) above the Atlantic. Powerful thrusters on the capsule propelled it up and out of harm’s way, as the rocket engines deliberately shut down and the booster tumbled out of control and exploded in a giant fireball. The capsule reached an altitude of about 27 miles (44 kilometers) before parachuting into the ocean just offshore to bring the test flight to a close. Everything appeared to go well despite the choppy seas and overcast skies. Within minutes, a recovery ship was alongside the capsule.Recycled from three previous launches, the SpaceX rocket was destroyed as it burst apart in flight and slammed in pieces into the sea. SpaceX normally tries to recover its boosters to drive down launch costs, landing them upright on a floating platform or back at the launch site.NASA’s commercial crew program manager, Kathy Lueders, said the launch abort test was “our last open milestone” before allowing SpaceX to launch Doug Hurley and Robert Behnken to the International Space Station. Their launch date will depend, in part, on whether NASA decides to keep them for months at the orbiting lab, versus just a week or two. A longer mission will require more training before flight.The astronauts monitored Sunday’s flight from the firing room. Hurley said it was “pretty neat to see” the capsule aboard the recovery ship within two hours. By all early accounts, the test was successful.“We’ll see what the data show and go from there,” Hurley said. “But it certainly is a confidence builder from the standpoint if you ever got into that situation, that Dragon can get us away from the booster quickly.”The astronauts also will have access to speed before liftoff. During a launch dress rehearsal Friday, Hurley and Behnken rode in a white Tesla Model X from Kennedy Space Center’s crew quarters to the launch pad, their sleek white and black spacesuits matching the electric sports car with wing-like doors. Musk, who also runs Tesla, used the cars to get around the space center Sunday.Delayed a day by bad weather, Sunday’s launch from Kennedy brought together hundreds of SpaceX, NASA and Air Force employees on land, at sea and in the air. Tourists and locals alike packed the adjoining visitor complex and nearby beaches to see the dramatic fiery spectacle of an out-of-control rocket. Musk brought along his own family, including his brother.NASA hired SpaceX and Boeing a decade ago to transport astronauts to and from the space station for billions of dollars. Both companies struggled with technical problems, adding years of delay and forcing NASA to shell out hundreds of millions of dollars extra for Russian rocket rides.After multiple cargo deliveries for NASA, SpaceX successfully flew an enhanced crew capsule to the space station last March without anyone on board, but it exploded a month later during ground testing. The emergency escape thrusters — the kind used in Sunday’s test — had to be retooled. In all, SpaceX has tested these powerful Super Draco thrusters some 700 times.Last month, meanwhile, Boeing’s Starliner crew capsule ended up in the wrong orbit on its first test flight and had to skip the space station. The previous month, only two of the Starliner’s three parachutes deployed during a launch abort test.Lueders said it’s too soon to know whether Boeing will need to send another Starliner to the space station without a crew or go straight to launching astronauts later this year. An investigation team is still looking into why the Starliner’s automated timer was off by 11 hours during the December test flight.The importance of launch escape was demonstrated in 2017 when two astronauts, an American and a Russian, were pulled to safety during a failed launch from Kazakhstan. They experienced up to seven times the force of gravity during the abort, but walked away from the accident.The SpaceX in-flight abort system, Musk pointed out, should be gentler for the crew and is good from the launch pad all the way to orbit.Musk said the Dragon’s escape system should work — in principle — even if the capsule is still attached when the rocket erupts in a fireball. He said that could look like “something out of ‘Star Wars’” with the capsule flying right out of a fireball.“Obviously we want to avoid doing that,” he quickly added, taking note of all the NASA personnel around him.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

Starbucks is opening the world's largest Roastery in Chicago.The company said the restaurant will open on November 15, overtaking Tokyo as its biggest location of the lavish offshoot. The four-story Chicago Roastery is 43,000 square feet and is replacing a former Crate and Barrel location in the city's Magnificent Mile neighborhood.Roasteries are intended to be tourist attractions in themselves. They feature specialty coffees and teas, on-premise roasters and massive coffee casks where freshly roasted beans are held. They also have bars with craft cocktails and serve fancier food than a normal Starbucks location.When Starbucks 647
Retirement is just a numbers game to Carl Jensen, who quit his job when he was miserable and decided his family of four could live off less.“We save a lot of money,” Jensen said. “We (do) the electricity ourselves, too.”He’s at home with his family full time and is making it work by slashing the family’s expenses."I had a really bad day at work, and I remember thinking I had this incredible stress. I can't do this for the next 15 to 20 years of my life,” he said. "I don't need a new car, so I don't have a new car. I don't care about my clothes ... so I don't buy brand new clothes. And I have an old phone because honestly I don't want to learn a new phone."The family lives on just more than ,000 a year, an amount his retirement funds generate, along with his wife’s job at a startup."I realized early, retirement is just a number game, and if you're a saver and can be a little bit frugal when you're younger and let the stock market work for you, you can actually stop working early.""People that haven't saved very much for retirement still have great choices available to them if they're flexible."Kim Curtis, Wealth Legacy Institute CEO, understands Jensen’s choice isn’t for everyone and says approaches can vary."The key around your 40s is making sure that you don't give up the savings your started in your 20s,” Curtis says.People in their 20s should focus on a savings routine such as a 401K, Roth IRA and keeping credit card balances low. Those in their 30s need to focus on asking for a raise and building their salaries.Curtis says they need to be bold.People in their 40s have a tougher time if they have growing children. It’s harder to save."The key around your 40s is making sure that you don't give up the savings your started in your 20s,” she said.Keep building the money in your 50s and consider not fully retiring until your 70s. It’s not as bad as it sounds."The idea of not working and stepping off and not having any new income from the time you retire through life expectancy is really a fallacy now because a lot of people have side hustles and a side hustle in retirement could be an Uber driver. It could be a wag walk or dog sitting,” Curtis says.People who can keep working will benefit most, though.For the average person, ,000 a month at age 62 is all social security provides. And it’s ,425 at age 66.If you don’t draw until you are 70 years old, it jumps to ,800 per month, Curtis says."That's significant."Jensen decided working is not for him, but he picks up contract jobs in between repairing and adding on to his house, which he does himself. 2611
