As the race for president in 2020 continues to heat up, data privacy experts say people should be taking a closer look at laws surrounding your data. "One of the toughest things is that for most of us, being online is no longer an optional thing; it's a mandatory thing," says Jennifer King, director of consumer privacy at The Center for Internet and Society at Stanford Law School. King tracks consumer privacy issues across the board. "In terms of the data that’s collected about you, it’s a pretty tough scenario," she says. "There is a lot of data collection that happens without our knowledge. Some people argue you consent to it, but because the consent is usually buried in a long terms and conditions and privacy policy, and so you consent, but most of us don’t read documents or be expected to practically.” King says companies like Facebook and Google have so much power over people's information because of a lack of laws and oversight. "We don’t have any laws frankly that restrict data collection or data use mostly across the board,” she explains. "There are particular areas where data collection is protected, so for instance in the health context, but that’s with a medical provider, so the world of Fit Bits and health tracking. [What] people do online, that’s not covered by privacy law.”She says people should care about data privacy, even if they have nothing to hide.“I hear that a lot, ‘I have nothing to hide. I'm not doing anything wrong,’ so it kind of assumes that privacy is about hiding things," she says. "I would argue it's about a lot more just controlling who you are and your ability to do things in the world.”When it comes to election season, King says she'd like to see more people with a better understand of the tech world in Washington. "Certainly, there is not enough. So, there is a real need for technological expertise in Congress,” she says. “That doesn’t necessarily mean elected officials. I would not expect most elected officials to come out of software companies. I would actually argue we’d be better off if we didn’t have our elected officials coming out of Silicon Valley, for example.”King hopes there will be more “reasonable protections” for consumers in the next few years. "There is only so much you can do as an individual, and that’s why it’s important to say that to pressure elected representatives to say that you want real data laws," she says. 2421

Boeing safely landed its crew capsule in the New Mexico desert Sunday after an aborted flight to the International Space Station that could hold up the company’s effort to launch astronauts for NASA next year.The Starliner descended into the Army’s White Sands Missile Range in the frigid predawn darkness, ending a two-day demo that should have lasted more than a week. A trio of red, white and blue parachutes popped open and airbags also inflated around the spacecraft to ease the impact. “We pinpoint landed it,” NASA Administrator Jim Bridenstine said at a post-landing briefing. The successful return capped a rocky start to a mission that was supposed to include a docking with the space station. Managers will review all the data before deciding whether to do another test flight or go straight to flying astronauts, said NASA’s Steve Stich. After seeing this first test flight cut short and the space station docking canceled because of an improperly set clock on the capsule, Boeing employees were relieved to get the Starliner back.Recovery teams cheered as they watched the capsule drift down through the air and make a bull’s-eye landing. The touchdown was broadcast live on NASA TV; infrared cameras painted the descending capsule in a ghostly white. As the sun rose, close-up views showed the large white and black capsule upright — with hardly any scorch marks from re-entry — next to a U.S. flag waving from a recovery vehicle. The astronauts assigned to the first Starliner crew — two from NASA and one from Boeing — were part of the welcoming committee. “A beautiful soft landing,” said NASA astronaut Mike Fincke. “Can’t wait to try it out.” It was the first American-made capsule designed for astronauts to make a ground landing after returning from orbit. NASA’s early crew capsules — Mercury, Gemini and Apollo — all had splashdowns. SpaceX’s Dragon capsule, which made its orbital debut last winter with a test dummy, also aims for the ocean at mission’s end.Minutes after touchdown, top NASA and Boeing officials poured into Mission Control in Houston to congratulate the team. The newly returned Starliner also got a personalized name: Calypso, after Jacques Cousteau’s boat.The capsule’s first trip to space began with a smooth rocket ride from Cape Canaveral on Friday. But barely a half hour into the flight, it failed to fire its thrusters to give chase to the space station and ended up in the wrong orbit. The problem was with the Starliner’s internal clock: It did not sync up with the Atlas V rocket and was off by 11 hours, according to Boeing’s Jim Chilton. The capsule burned so much fuel trying to orient itself in orbit that there wasn’t enough left for a space station rendezvous. Flight controllers tried to correct the problem, but between the spacecraft’s position and a gap in communications, their signals did not get through. They later managed to reset the clock. Boeing is still trying to figure out how the timing error occurred. The mission lasted nearly 50 hours and included 33 orbits around the Earth, about 100 orbits fewer than planned. A test dummy named Rosie the Rocketeer — after Rosie the Riveter from World War II — rode in the commander’s seat. Also returning were holiday presents, clothes and food that should have been delivered to the space station crew.Even though not all goals were met including a station docking, “in my eyes, it was a huge success,” said Boeing flight director Richard Jones.There were no parachute problems this time. Last month, only two parachutes deployed during an atmospheric test because workers failed to connect a pin in the rigging.“We didn’t do everything we wanted to do, but we don’t see anything wrong with this spaceship right now,” despite the timing error, Chilton said. He apologized to the six space station residents for not delivering their Christmas presents. Boeing had been shooting for its first astronaut launch in the first half of 2020. This capsule is supposed to be recycled for the second flight with crew; each Starliner is built to fly in space 10 times.The capsule will return to Florida’s Kennedy Space Center in two weeks for inspections and refurbishments.“We’ve got a lot of learning in front of us,” Bridenstine said. “But we have enough information and data to where we can keep moving forward in a very positive way.Despite its own setbacks, SpaceX remains in the lead in NASA’s commercial crew program.SpaceX’s Dragon crew capsule successfully completed its first orbital demo last March. While the flight to the space station went well, the capsule exploded a month later on a test stand at Cape Canaveral. If a launch abort test goes well next month, SpaceX could start launching NASA astronauts by spring and end a nearly nine-year gap in flying people from Cape Canaveral.As its space shuttle program was winding down, NASA looked to private industry to take over cargo and crew deliveries to the space station. SpaceX kicked off supply runs in 2012. Two years later, NASA hired SpaceX and Boeing to ferry astronauts to the orbiting lab. SpaceX got .6 billion under NASA’s commercial crew program, while Boeing received more than billion.The goal was to launch NASA astronauts by 2017.Because of delays, NASA is looking to buy another two seats on Russian rockets in 2020 and 2021 to guarantee a continuing U.S. presence on the space station. Even when private companies are regularly carrying up astronauts for NASA, the space agency always will reserve a seat for a Russian in exchange for a free U.S. seat on a Soyuz.Over the years, these Soyuz rides have cost NASA up to million apiece, with the tab totaling in the billions.A recent audit by NASA’s inspector general found a Starliner seat will cost slightly more than that, with a Dragon seat going for just over half the price.___The Associated Press Health and Science Department receives 5902

AUORA, Colo. – The coronavirus epidemic is having a major impact on small Asian-run businesses in the United States. Some places say the number of customers has dropped by half. The Pacific Ocean Market has been a staple of Asian American businesses in Aurora, Colorado, for years."There is such a variety of places to eat and different types of food and things you don't normally see in the ordinary market," said one customer of the market. Within the last month, business at the market has been somewhat of a roller coaster ride since the new coronavirus first surfaced. "With people panicking across the country, we've heard stories in New York saying there's no more rice and Atlanta there's no more rice, so people have been continuing to stock up on that," said Betty Lam, one of the two daughters of the owner of the market. The outbreak began in China and quickly spread across Asia. Since then, a growing number of coronavirus cases have been confirmed in the U.S. and customers seem to be staying away from Asian American businesses as a precaution.According to The New York Times, business at shops that sell Asian products dropped by 70 percent in the first two weeks of February. The Chinese Merchants Association in San Francisco says foot traffic in their Chinatown district dropped by 50 percent."It's a little off and on right now,” said Lam. “We're not too sure how it's going to go." Lam says she’s already heard of businesses being affected."From the restaurants we work with, we have seen and heard that they're not doing very good and there have been a lot of customers and loyal customers who haven't been going to their restaurants due to the coronavirus." Lam hopes that the public continues to be educated and aware. That way, Asian businesses can still thrive during these times. 1819

  

BOULDER, Colo. – A Boulder, Colorado, family says their son was stuck with a hypodermic needle while playing near a creek by the Park East Park. Now, the family is warning parents to have a talk with their children.Wade Green says his four-year-old son was on a play date with another kid when he found a needle. Green’s son picked up the needle and started playing with it. The nanny who was watching him asked the four-year-old what it was and he said it was a pH meter. It wasn’t until Green’s son made it home and showed the needle to his wife that someone realized what it was. The family lives near their pediatrician and immediately took their son to see him.“Examining him a little further, (the doctor) noticed two needle marks in his hand,” Green said. “When it happens to your own child, it’s just a heart wrenching.”So far, the four-year-old has taken two tests to see whether he has contracted a transmittable disease. He will have to undergo two more tests before being given the all-clear by doctors. This is not the only time people in the community have found needles laying around.“Two days before, a neighbor had told my wife that they had found a needle at the park east playground and they weren’t going to go there anymore because they didn’t feel like it was a safe place to take their kids,” Green said. The nanny that was watching their son also found a needle along the road last weekend. At the Boulder City Council meeting this week, 1474
