Spending a year in space not only changes your outlook, it transforms your genes.Preliminary results from NASA's Twins Study reveal that 7% of astronaut Scott Kelly's genes did not return to normal after his return to Earth two years ago.The study looks at what happened to Kelly before, during and after he spent one year aboard the International Space Station through an extensive comparison with his identical twin, Mark, who remained on Earth.NASA has learned that the formerly identical twins are no longer genetically the same. 561

Someone out there is sitting on a lottery ticket worth more than .5 billion, but has not stepped forward to claim the prize, according to ABC News. On Oct. 23, a single winning ticket was purchased in South Carolina for the largest Mega Millions jackpot in history. The ticket is also the single most valuable lottery ticket in US history. "We have not heard that the winner in South Carolina has come forward," Mega Millions administrator Seth Elkin told ABC News. The winner has 180 days to claim the prize. That means the winning ticket does not have to be claimed until April. If no winner comes forward, each participating state in the Mega Millions game will get back all the money that state contributed to the unclaimed jackpot, the lottery says on its website. The amount of money that goes unclaimed in state lottery programs is quite staggering. Nearly billion went unclaimed during a 12-month period from late 2016 through early 2017, lottery expert Brett Jacobson told CNN. While most of the unclaimed lottery winnings are from smaller prizes, there have been a few notable examples of massive jackpots going unclaimed. The largest known unclaimed lottery ticket was sold in Georgia in 2011 worth million. Elkin told ABC News that it would be prudent for whoever is holding the winning lottery ticket to sign it, keep it somewhere safe and consult a financial advisor before claiming the prize.  1490

SPRING VALLEY, Calif. (KGTV) - Despite Governor Gavin Newsom's orders, students at a private school in Spring Valley are scheduled to return to class in a few weeks.When Heartland Christian Homeschool Center begins its school year on Sept. 1, it will include in-school learning. Classified as a private school, the pre-kindergarten-to-12th grade school combines homeschooling with several days of in-person instruction every week.The plans come despite the governor’s orders banning in-school classes for counties still on the watch list. Right now, San Diego County remains on that list.Principal Lynda Hansen told ABC 10news, it's "important" for kids to be back in class, adding her school is "following all CDC guidelines."The state is allowing elementary schools to apply for waivers to the COVID-19 orders. Hansen says she'll apply for the waiver, but it likely won't affect her decision to open.The school’s COVID-19 section does list its precautions, including stepped-up disinfecting, encouraging social distancing, and masks for staff when close to students. Masks will not be mandatory for students.The mask issue is a point of concern for students at another private school with similar plans. Last week, ABC 10News reported on Foothills Christian Middle School in El Cajon.A letter sent to parents spelled out reopening plans in September, including masks being optional. That led to frustration for parents who emailed ABC 10News. The school cited a lack of evidence that masks prevent COVID-19 transmission in children.A county spokesperson says the have several tools for private schools out of compliance, beginning with education and on-site visits. Other options citations, cease-and-desist orders, and closure orders.Heartland Christian Homeschool Center issued the following statement: "Heartland Christian Homeschool Center Inc. is fully committed to complying with every lawful requirement of federal, state, and local government. Also, Heartland is an alternative educational choice. It is our aim to provide support, enrichment, and records for homeschooling families. Unlike traditional schools, our students are not on campus full-time. Our expectation is that San Diego County will be off the Governor's watch list by the fall. We are planning accordingly, following the CDC guidelines for schools. Our parents have been overwhelmingly supportive ..." 2387

Smoke masks. Eye drops. No outdoor exercise. This is how Californians are trying to cope with wildfires choking the state, but experts say an increase in serious health problems may be almost inevitable for vulnerable residents as the disasters become more commonplace.Research suggests children, the elderly and those with existing health problems are most at risk.Short-term exposure to wildfire smoke can worsen existing asthma and lung disease, leading to emergency room treatment or hospitalization, studies have shown.Increases in doctor visits or hospital treatment for respiratory infections, bronchitis and pneumonia in otherwise healthy people also have been found during and after wildfires.RELATED: Missing-persons list tops 600 in Camp FireSome studies also have found increases in ER visits for heart attacks and strokes in people with existing heart disease on heavy smoke days during previous California wildfires, echoing research on potential risks from urban air pollution.For most healthy people, exposure to wildfire smoke is just an annoyance, causing burning eyes, scratchy throats or chest discomfort that all disappear when the smoke clears.But doctors, scientists and public health officials are concerned that the changing face of wildfires will pose a much broader health hazard."Wildfire season used to be June to late September. Now it seems to be happening all year round. We need to be adapting to that," Dr. Wayne Cascio, a U.S. Environmental Protection Agency cardiologist, said this week.In an overview published earlier this year, Cascio wrote that the increasing frequency of large wildland fires, urban expansion into wooded areas and an aging population are all increasing the number of people at risk for health problems from fires.Wood smoke contains some of the same toxic chemicals as urban air pollution, along with tiny particles of vapor and soot 30 times thinner than a human hair. These can infiltrate the bloodstream, potentially causing inflammation and blood vessel damage even in healthy people, research on urban air pollution has shown. Studies have linked heart attacks and cancer with long-term exposure to air pollution.Whether exposure to wildfire smoke carries the same risks is uncertain, and determining harm from smog versus wildfire smoke can be tricky, especially with wind-swept California wildfires spreading thick smoke hundreds of miles away into smoggy big cities."That is the big question," said Dr. John Balmes, a University of California, San Francisco, professor of medicine who studies air pollution."Very little is known about the long-term effects of wildfire smoke because it's hard to study populations years after a wildfire," Balmes said.Decreased lung function has been found in healthy firefighters during fire season. They tend to recover but federal legislation signed this year will establish a U.S. registry tracking firefighters and potential risks for various cancers, including lung cancer. Some previous studies suggested a risk.Balmes noted that increased lung cancer rates have been found in women in developing countries who spend every day cooking over wood fires.That kind of extreme exposure doesn't typically happen with wildfires, but experts worry about the kinds of health damage that may emerge for firefighters and residents with these blazes occurring so often.Whether that includes more cancer is unknown. "We're concerned about that," Balmes said.Regular folks breathing in all that smoke worry about the risks too.Smoke from the fire that decimated the Northern California city of Paradise darkened skies this week in San Francisco, nearly 200 miles southwest, and the air smelled "like you were camping," said Michael Northover, a contractor.He and his 14-year-old son have first-time sinus infections that Northover blames on the smoke."We're all kind of feeling it," Northover said.The smoke was so thick in San Francisco, the skyline was barely visible from across the Bay. The city's iconic open-air cable cars that are popular with tourists were pulled off the streets Thursday because of the bad air.An Environmental Protection Agency website said air quality in Sacramento was "hazardous" Thursday and San Francisco's was "very unhealthy." Many people walking around the cities wore face masks.Most schools in San Francisco, Sacramento, Oakland and Folsom said they would be closed Friday. At least six universities in Northern California canceled classes Thursday.At Chico State University, 11 miles (18 kilometers) from Paradise, ash fell this week and classes were canceled until after Thanksgiving."It's kind of freaky to see your whole town wearing air masks and trying to get out of smoke," said freshman Mason West, 18. "You can see the particles. Obviously, it's probably not good to be breathing that stuff in."West returned home this week to Santa Rosa, hard hit by last year's wine country fires, only to find it shrouded in smoke from the Paradise fire 100 miles (160 kilometers) away. West's family had to evacuate last year for a week, but their home was spared."It's as bad here as it was in Chico," West said. "It almost feels like you just can't get away from it."Smoke has been so thick in Santa Rosa that researchers postponed a door-to-door survey there for a study of health effects of last year's fire."We didn't feel we could justify our volunteer interns going knocking on doors when all the air quality alerts were saying stay indoors," said Irva Hertz-Picciotto, a public health researcher at the University of California, Davis. The study includes an online survey of households affected by last year's fire, with responses from about 6,000 people so far.Preliminary data show widespread respiratory problems, eye irritations, anxiety, depression and sleep problems around the time of the fire and months later."Conventional thinking is that these effects related to fires are transient. It's not entirely clear that's the case," Hertz-Picciotto said.Researchers also will be analyzing cord blood and placentas collected from a few dozen women who were pregnant during the fire, seeking evidence of stress markers or exposure to smoke chemicals.They hope to continue the study for years, seeking evidence of long-term physical and emotional harms to fire evacuees and their children.Other studies have linked emotional stress in pregnant women to developmental problems in their children and "this was quite a stress," Hertz-Picciotto said.It's a kind of stress that many people need to prepare for as the climate warms and wildfires proliferate, she said."Any of us could wake up tomorrow and lose everything we own," she said. "It's pretty scary."___Follow AP Medical Writer Lindsey Tanner at https://twitter.com/LindseyTanner .
