Airbnb announced new rules for New Year's Eve to prevent parties and large gatherings at its properties amid a surge in coronavirus cases.The vacation rental company released its plan on Thursday to limit rentals in the United States, the United Kingdom, Canada, Mexico, Australia, France, and Spain.The new measures state that Airbnb would require guests who don't have a positive review history to book a minimum of two nights for any stay, including Dec. 31. Any guests with reservations on Dec. 31 must swear that they will not throw a party under threat of legal charges.The company said that guests who have a history of positive reviews on Airbnb would not be subject to this restriction.The company said it would allow already-booked one-night reservations to continue as planned since their "data has historically shown that one-night New Year’s Eve bookings made prior to now very rarely lead to unauthorized parties." 936

After almost two years circling an ancient asteroid hundreds of millions of miles away, a NASA spacecraft this week will attempt to descend to the treacherous, boulder-packed surface and snatch a handful of rubble.The drama unfolds Tuesday as the U.S. takes its first crack at collecting asteroid samples for return to Earth, a feat accomplished so far only by Japan.Brimming with names inspired by Egyptian mythology, the Osiris-Rex mission is looking to bring back at least 2 ounces (60 grams) worth of asteroid Bennu, the biggest otherworldly haul from beyond the moon.The van-sized spacecraft is aiming for the relatively flat middle of a tennis court-sized crater named Nightingale — a spot comparable to a few parking places here on Earth. Boulders as big as buildings loom over the targeted touchdown zone.“So for some perspective, the next time you park your car in front of your house or in front of a coffee shop and walk inside, think about the challenge of navigating Osiris-Rex into one of these spots from 200 million miles away,” said NASA’s deputy project manager Mike Moreau.Once it drops out of its half-mile-high (0.75 kilometer-high) orbit around Bennu, the spacecraft will take a deliberate four hours to make it all the way down, to just above the surface.Then the action cranks up when Osiris-Rex’s 11-foot (3.4-meter) arm reaches out and touches Bennu. Contact should last five to 10 seconds, just long enough to shoot out pressurized nitrogen gas and suck up the churned dirt and gravel. Programmed in advance, the spacecraft will operate autonomously during the unprecedented touch-and-go maneuver. With an 18-minute lag in radio communication each way, ground controllers for spacecraft builder Lockheed Martin near Denver can’t intervene.If the first attempt doesn’t work, Osiris-Rex can try again. Any collected samples won’t reach Earth until 2023.While NASA has brought back comet dust and solar wind particles, it’s never attempted to sample one of the nearly 1 million known asteroids lurking in our solar system until now. Japan, meanwhile, expects to get samples from asteroid Ryugu in December — in the milligrams at most — 10 years after bringing back specks from asteroid Itokawa.Bennu is an asteroid picker’s paradise.The big, black, roundish, carbon-rich space rock — taller than New York’s Empire State Building — was around when our solar system was forming 4.5 billion years ago. Scientists consider it a time capsule full of pristine building blocks that could help explain how life formed on Earth and possibly elsewhere.“This is all about understanding our origins,” said the mission’s principal scientist, Dante Lauretta of the University of Arizona.There also are selfish reasons for getting to know Bennu better.The solar-orbiting asteroid, which swings by Earth every six years, could take aim at us late in the next century. NASA puts the odds of an impact at 1-in-2,700. The more scientists know about potentially menacing asteroids like Bennu, the safer Earth will be.When Osiris-Rex blasted off in 2016 on the more than 0 million mission, scientists envisioned sandy stretches at Bennu. So the spacecraft was designed to ingest small pebbles less than an inch (2 centimeters) across.Scientists were stunned to find massive rocks and chunky gravel all over the place when the spacecraft arrived in 2018. And pebbles were occasionally seen shooting off the asteroid, falling back and sometimes ricocheting off again in a cosmic game of ping-pong.With so much rough terrain, engineers scrambled to aim for a tighter spot than originally anticipated. Nightingale Crater, the prime target, appears to have the biggest abundance of fine grains, but boulders still abound, including one dubbed Mount Doom.Then COVID-19 struck.The team fell behind and bumped the second and final touch-and-go dress rehearsal for the spacecraft to August. That pushed the sample grab to October.“Returning a sample is hard,” said NASA’s science mission chief, Thomas Zurbuchen. “The COVID made it even harder.”Osiris-Rex has three bottles of nitrogen gas, which means it can touch down three times — no more.The spacecraft automatically will back away if it encounters unexpected hazards like big rocks that could cause it to tip over. And there’s a chance it will touch down safely, but fail to collect enough rubble.In either case, the spacecraft would return to orbit around Bennu and try again in January at another location.With the first try finally here, Lauretta is worried, nervous, excited “and confident we have done everything possible to ensure a safe sampling.”___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

After issuing previous guidance that encouraged schools to close in areas with high transmission of the coronavirus, the CDC is now emphasizing that schools reopen this fall.The guidance issued on Thursday is in line with a Trump administration priority to reopen schools this fall.“It is critically important for our public health to open schools this fall,” said CDC Director Dr. Robert R. Redfield. “The CDC resources released today will help parents, teachers and administrators make practical, safety-focused decisions as this school year begins. I know this has been a difficult time for our Nation’s families. School closures have disrupted normal ways of life for children and parents, and they have had negative health consequences on our youth. CDC is prepared to work with K-12 schools to safely reopen while protecting the most vulnerable.”Now in areas with, as the CDC calls it, "substantial, uncontrolled transmission" of the coronavirus, "Schools should work closely with local health officials to make decisions on whether to maintain school operations. The health, safety, and wellbeing of students, teachers, staff and their families is the most important consideration in determining whether school closure is a necessary step. Communities can support schools staying open by implementing strategies that decrease a community’s level of transmission. However, if community transmission levels cannot be decreased, school closure is an important consideration."In areas with substantial, controlled transmission, "Significant mitigation strategies are necessary." In addition, social distancing and face covering policies should be implemented, the CDC said.Previous guidance called for schools in areas with substantial community transmission (the CDC did not distinguish between uncontrolled or controlled) to, "Implement extended school dismissals (e.g., dismissals for longer than two weeks). This longer-term, and likely broader-reaching, dismissal strategy is intended to slow transmission rates of COVID-19 in the community. During extended school dismissals, also cancel extracurricular group activities, school-based afterschool programs, and large events."In previous guidance, the CDC called on schools to keep students 6 feet apart. But many classrooms do not have the space to properly socially distance students. The Trump administration’s response appears to be a 5 billion request to Congress. President Donald Trump said that the funds, in part, could be used for schools to open additional spaces and hire additional staff in order to help space students.The CDC said that the “best available evidence from countries that have opened schools indicates that COVID-19 poses low risks to school-aged children, at least in areas with low community transmission, and suggests that children are unlikely to be major drivers of the spread of the virus.”But that guidance contradicts a South Korean study published by the CDC earlier this week.The study said that while children under age 9 were less likely to spread the virus, youth ages 10 through 19 were just as likely as adults of spreading the virus.The study also found that closing schools in several Chinese cities, including Wuhan, that school closures and social distancing significantly reduced the rate of COVID-19 among contacts of school-aged children.“The role of household transmission of SARS-CoV-2 amid reopening of schools and loosening of social distancing underscores the need for a time-sensitive epidemiologic study to guide public health policy,” the researchers wrote.In its new guidance, the CDC said that extended school closures are harmful to children and can lead to severe learning loss, and the need for in-person instruction is particularly important for students with heightened behavioral needs.The American Federation of Teachers this week pointed toward a three-point plan that the US should implement for reopening schools.“Our plan details three conditions essential for schools to reopen,” wrote Randi Weingarten, president of the American Federation of Teachers. “First, the average daily community infection rate among those tested for the coronavirus must be very low. (New York Gov. Andrew Cuomo has required the rate not to exceed 5 percent for at least 14 days.) Second, schools must employ public health protocols, including 6-feet social distancing, masks, deep cleaning and handwashing stations. Third, adequate resources must be available to enact these safeguards, including funding for additional nurses, guidance counselors and teachers to reduce class size.”But the CDC also weighed the concerns of the coronavirus against providing physical activity, food and safety for students. The CDC said studies project that the childhood obesity rate would increase by 2.4% if schools remained closed through December.This guidance comes as cases in the US steadily increased earlier this month, prompting coronavirus death counts to rise in recent days. The US had back to back days of more than 1,000 people reportedly dying from coronavirus-related illnesses, according to Johns Hopkins University.To read the CDC’s latest guidance, click here. 5184
