As an excessive heat warning hits Southern California, beachgoers are staying onshore, despite the high temperatures.“My wife was a little freaked out,” said local surfer Craig Neil. “She sent me a text and said she’s getting the kids out of the water.”Out of the water because of what’s lurking inside the section of the Pacific Ocean.“We had a confirmed shark sighting,” said another surfer.A 12-foot great white shark spotted just off the San Clemente Pier, something locals say is happening more often.“It seems fairly normal here,” Neil said. “There’s usually shark sightings every month or two at least.”Now a new study is showing the number of great white sharks is rising off the California coast.“The simple reason for that is we’ve done a better job of protecting them,” said Chris Lowe a professor of marine biology and the director of the Shark Lab at California State University, Long Beach. “We’ve done a better job managing our fisheries and believe it or not, the water has gotten cleaner over the last 40 years."Lowe and his team have spent the past several years tracking these aquatic predators, saying while they are seeing more sharks in the water, they’re not seeing more attacks.“So, that’s all good news but we just have to learn ways to be better guests in somebody else’s home,” he said.A home with a now expanding zip code with more great white sharks moving up the coast.“Now we’re starting to see them in places off Monterey, a place where we hadn’t seen them before and this is largely due to the oceans getting warmer,” Lowe said.Lowe says this change in temperature is being seen around the world, which is something he believes will cause more great white sharks to relocate to colder waters, which could disrupt the ocean’s food chain and also alter the ecosystem.“If they get moved to a location where there’s less food, they’re just not going to do very well,” he said. “In fact, their populations may start to go down or they start to feed on something they never fed on before.”Back on the beach, stranded surfers like Neil stare at closure signs waiting for lifeguards to reopen the water, saying the ocean is the shark’s turf and that we’re just guests swimming in it. 2216

As health experts warn about rising coronavirus cases from spread at indoor gatherings, a new website backed by recent research is trying to help people understand just how many people in what size space is risky for infection. Which could come in handy as some people consider small holiday gatherings.It’s more risky to be in a small room compared to a large gym. If people are calm and quiet, it is safer than singing or exercising no matter how distant they are.Given these types of scenarios, and the “rapidly advancing science” of how COVID-19 droplets behave, scientists at the Massachusetts Institute of Technology created the COVID-19 Indoor Safety Guideline application.Here’s an example:An average suburban house that is 2,000 square feet, with 25 people inside wearing cotton masks and talking in a whisper, can reduce their risk of transmission by only staying inside for 4 hours.If those same 25 people, in the same house, are not wearing a mask and are talking normally, the length of time to reduce transmission drops to just 50 minutes.And if those 25 people, in the same house, are singing along to Christmas music, without masks on, that time to safely reduce COVID-19 transmission indoors drops even further to just 8 minutes.If the size of the gathering is only 5 people, and there is still singing, no mask wearing, and it’s still a 2,000 square foot house, it becomes unsafe after just 27 minutes.The MIT website offers users the ability to select room size, number of people and length of time, then using previous research and scientific knowledge of airborne viruses, it predicts the risk of the indoor event. Users can change elements of the situation, like room size, mask wearing, ventilation, etc.Click here to visit the Indoor Safety Guideline website.In a restaurant, to reduce transmission, 50 people without masks and talking normally should stay for only two hours. If the restaurant has 100 people, to reduce transmission risk, they should only remain inside for 64 minutes.The researchers note current general social distancing guidelines (remain 6 feet apart) suggest 138 people would reduce their risk in the same size of space for an indefinite amount of time.Another example, a Boeing 737, the researchers’ model predicts 100 people can be onboard a 737 wearing masks and still reduce their risk of transmission by staying onboard less than 6 hours.The CDC updated their guidance about COVID-19 this fall, acknowledging ongoing research that shows coronavirus droplets “can remain suspended for many minutes to hours (in the air) and travel far from the source on air currents.”The Centers for Disease Control and Prevention also says coronavirus droplets can remain even when an infected person has left the room and can travel farther than six feet. 2800

An American Airlines cleaning crew found "what appears to be a fetus" in the lavatory of a plane early Tuesday morning, spokesman Justin Franco told CNN by phone.The Office of the Chief Medical Examiner in New York confirmed it is "investigating what we believe to be a human fetus found deceased on an airplane," said Aja Worthy-Davis, executive director for public affairs."We will release determination when investigation is complete."The plane arrived to LaGuardia Airport from Charlotte, North Carolina, late Monday evening, and the discovery was made during the aircraft's scheduled cleaning at around 5 a.m. Tuesday morning.The cleaning crew immediately contacted their manager, who in turn contacted law enforcement, Franco said."As we continue to learn more about this tragic and sensitive situation, we are actively cooperating with law enforcement in their investigation," a statement from American Airlines said.The Port Authority Police, which has jurisdiction over New York's LaGuardia Airport, deferred calls on the incident to the Queens District Attorney's office.The Queens District Attorney's office is looking into the matter, a spokeswoman confirmed to CNN, adding that they may have additional information to share Tuesday afternoon. 1263

Applebee's announced Tuesday it will close as many as 80 restaurants nationwide as the chain continues to struggle attracting young diners.The announcement comes after Applebee's parent company, DineEquity, said in August it would close more than 100 restaurants.It's not clear which Applebee's locations would close, but according to Fortune, remaining locations will be judged on a number of criteria. “The expected closures will be based on several criteria, including meeting our brand and image standards as well as operational results,” DineEquity told Fortune in a statement.DineEquity also announced it would close up to 40 IHOP locations, though it plans to open as many as 100 new locations of the breakfast chain throughout the country.DineEquity's stock has soared since the announcement, rising nearly 20 percent on Tuesday.Alex Hider is a writer for the E.W.
