The Geminid meteor shower peaks this week, so hope for clear skies that will let you see a beautiful show of green fireballs on Thursday and Friday. This will be the last -- and strongest -- meteor shower of the year, according to NASA.This phenomenon was first recorded in 1862 and causes a show each December.In the hours before sunrise Friday, the most meteors will be visible in the North American sky, peaking about 7:30 a.m. ET, predicts Sky & Telescope. To see when they will peak in your part of the world, check here.But the morning isn't your only chance. On Thursday and Friday, keep an eye on the sky a few hours after sunset -- just keep the moon at your back.Although the Geminid shower is known for its "shooting stars," the number of meteors visible depends on the time and how dark it is. There will be fewer of them earlier in the evening, but the shower should hit a maximum of about 100 per hour around 2 a.m., NASA said. For those in the suburbs, expect about 30 to 40 per hour. And if you're in a city like New York, San Francisco or Atlanta, you probably won't see anything.Early evening meteors may be longer, with dramatic streaks that last several seconds. Later on, the meteors will present quicker streaks or leave trails of smoke that appear to glow.The asteroid 3200 Phaethon is responsible for this meteor shower, which is unusual because comets usually create meteor showers with icy debris. Scientists have debated the very nature of what Phaethon is. The closely tracked near-Earth asteroid has been likened to comets, so it's been called a "rock comet."Phaethon was discovered in October 1983 and named after the Greek myth about the son of Helios, the sun god, because it closely approaches our sun.Phaethon orbits the sun closer than any other asteroid and takes 1.4 years to orbit it. The asteroid heats to about 1,300 degrees Fahrenheit on closest approach to the sun, which causes it to shed dusty debris.These particles cause the meteor shower when they plunge into Earth's atmosphere at 22 miles per second, vaporizing in the streaks we call "shooting stars."If you live in an urban area, you may want to drive to a place that isn't littered with city lights that will obstruct your view. If you're able to find an area unaffected by light pollution, meteors could be visible every couple of minutes from 10 p.m. until dawn.Find an open area with a wide view of the sky, and don't forget to bundle up. Make sure you have a chair or blanket so you can look straight up. And give your eyes about 20 to 30 minutes to adjust to the darkness -- without looking at your phone -- so meteors are easier to spot.While you're keeping an eye out for the meteor shower, you might see a small, foggy green patch in the sky, NASA said. That will be Comet 46P/Wirtanen, which is making its closest approach to Earth -- within 7 million miles -- for the next 20 years. And it will be visible to the naked eye. The comet is expected to come closest to Earth and peak Sunday. 3007

The FBI issued a warning on Wednesday alerting Americans to scammers using the coronavirus to solicit donations for fraudulent charities.Federal law enforcement officials say they have received reports that scammers are using the pandemic to steal money, personal information or both.The FBI says that often, the fraudsters will use the name of a real charity to conduct their scam. The FBI adds that criminals may spoof their caller ID number to make it appear the call originated from a legitimate charity.“Be careful,” the FBI said.The FBI offered the following advice to Americans:The best way to protect yourself is by doing your research. Here are some tips on how to avoid becoming a victim of a charity fraud:Do your homework when it comes to donations, whether you’re donating through charities, social media, or crowdfunding websites.Look for online reviews of charity organizations or use information from your state’s regulator of charities or from websites like the Better Business Bureau, give.org, charitynavigator.org, or charitywatch.org to check on the legitimacy of charitable organizations.Before donating, ask how much of the donation will go toward the program or cause you want to support. Every organization has administrative costs, and it’s important to understand those structures.Never pay by gift card or wire transfer. Credit cards are safer.After making a donation, be sure to review your financial accounts to ensure additional funds are not deducted or charged.Always do your research before clicking on links purporting to provide information on the virus, purchasing COVID-related products online, or providing your personal information in order to receive money or other benefits. 1724

The coronavirus pandemic, and the resulting lockdowns, travel restrictions and business closures, have caused many people to adjust their living situation either temporarily or permanently. As a result, the number of young adults, those ages 18-to-29, who live with their parents is at an all-time high.The Pew Research Center reports 52 percent of young adults lived with one or both of their parents in July. That translates to about 26,6 million young adults living with parents. The percentage of young adults living with their parents was 47 percent in February, and for most of 2019. The new data was released Friday.The research firm compared the data to available census data, and found the census of 1940, taken toward the end of the Great Depression, reported 48 percent of young adults lived with their parents."The peak may have been higher during the worst of the Great Depression in the 1930s, but there is no data for that period,” researchers stated.The percentage of young adults living with their parents has been above 50 percent since April, slowly climbing. This is the first time the percentage has been above 50 since data became available in 1976.Earlier research from the group found one-in-ten young adults reported relocating temporarily or permanently because of the coronavirus pandemic. More than any other age group.The 18-to-29 age group was hit hard with pandemic-related job losses, service-sector job furloughs and college campus shutdowns. The younger half of this demo saw the biggest increase in moving back in with parents; 71 percent of 18-to-24-year-olds now live with their parents.These new living arrangements, where adult children are living with their parents, could have a trickle down effect on the US economy. Pew Research Center suggests the results of the majority of young adults moving in with parents could lead to a slowdown in demand for housing and household goods.“There also may be a decline in the number of renters and homeowners, and in overall housing activity,” they stated.The overwhelming majority of young adults who live with their parents live in their parents’ home, roughly 88 percent. The remaining either had their parents move in with them or the head of the household is another family member. 2276

The Food and Drug Administration resisted pressure from the Trump administration on Tuesday by releasing a set of guidelines that could push an emergency use authorization of a coronavirus vaccine past Election Day.The FDA’s new guidance notes that an Oct. 22 meeting of its Vaccines and Related Biological Products Advisory Committee will not be to discuss specific vaccine candidates. The FDA noted that a vaccine candidate must be at least 50% effective. Vaccine candidates should include a median follow-up duration of at least two months after completion of the full vaccination regimen to help provide adequate information to assess a vaccine’s risk-benefit."Being open and clear about the circumstances under which the issuance of an emergency use authorization for a COVID-19 vaccine would be appropriate is critical to building public confidence and ensuring the use of COVID-19 vaccines once available,” Peter Marks, M.D., Ph.D., director of the FDA's Center for Biologics Evaluation and Research, said. The FDA's new guidance on emergency use authorization of COVID-19 vaccines underscores that commitment by further outlining the process and recommended scientific data and information that would support an emergency use authorization decision.“In addition to outlining our expectations for vaccine sponsors, we also hope the agency's guidance on COVID-19 vaccines helps the public understand our science-based decision-making process that assures vaccine quality, safety and efficacy for any vaccine that is authorized or approved."Trump previously said he would consider overruling the FDA on its vaccine guidelines in hopes of speeding up the process. There is both health and economic pressure for a vaccine to be developed as the coronavirus continues to claim an average of 800 US lives a day, according to Johns Hopkins University data. The number of deaths per day related to the coronavirus is expected to increase as the weather gets colder, according to the University of Washington’s Institute for Health Metrics and Evaluation.On Tuesday, House Speaker Nancy Pelosi blasted the Trump administration for involving itself in the vaccine approval process.“Trust in the vaccine is key to the acceptance of the American people, which is essential to crushing the virus.“The White House’s decision to reject FDA medical experts’ minimum safety and efficacy standards for emergency use authorization of a vaccine is an extremely dangerous act. We are all praying for a safe and effective vaccine as soon as possible, but the damage of the Trump Administration rushing a vaccine before it is known to be safe and effective could be catastrophic."Dr. Anthony Fauci told CNN's Chris Cuomo on Monday that he expects a vaccine candidate to be given an emergency use authorization by the end of 2020. "By the time we get to November, December, maybe earlier, I don't think it's going to be earlier, but it's still possible," Fauci said. "It will be early, but I think comfortably around November or December we'll know whether or not the vaccine is safe and effective. I actually am cautiously optimistic from what I've seen about preliminary data in phase one, that there's a very good chance we'll have a safe and effective vaccine." 3256

The Christian evangelist who attempted to convert one of the world's last remaining isolated tribes wrote of his convictions in pursuing the mission even in the face of open hostility and attempts on his life, according to diary entries and notes.In excerpts from his journal, John Allen Chau, the American who is believed to have been killed by members of the isolationist Sentinelese tribe on a tiny, remote island in the Bay of Bengal, wrote of returning to the island to continue his attempts at conversion even after a tribesman shot at him with a bow and arrow, piercing a Bible he was carrying."I hollered, 'My name is John, I love you and Jesus loves you,'" he wrote in his diary, pages of which were shared by his mother with the Washington Post. Shortly after, a young member of the tribe shot at him, according to his account.In pages left with the fishermen who facilitated his trip to the island, his musings are a clear indication of his desire to convert the tribe."Lord, is this island Satan's last stronghold where none have heard or even had the chance to hear your name?" he wrote.His notes indicate that he knew the trip was illegal, describing how the small fishing vessel transported him to the isolated island under cover of darkness, evading patrols."God Himself was hiding us from the Coast Guard and many patrols," he wrote.All seven locals who facilitated the trip have been arrested. 1419
