Two men were attacked by sharks off the eastern coast of Florida.The incidents occurred within an hour of one another, 100 miles apart.The first attack took place around 3:30 p.m. ET Saturday near Jacksonville Beach Pier, according to a witness. RJ Berger said he and his friend Frank O'Rourke were surfing together when a shark knocked O'Rourke off of his board and into the water.The four-foot shark then bit O'Rourke on the arm, Berger said.The two men managed to catch waves back to shore, where a lifeguard treated O'Rourke for his injuries.Instead of heading straight to the hospital, the two men decided to go to a bar, Berger said, where the shark attack earned the pair lots of free drinks."Everyone's like, 'you got bit by a shark, I'll buy you all the drinks you want,'" Berger told CNN.O'Rourke is a professional surfer and eager to get back out in water. He planned to see a doctor on Sunday and could probably use a stitch or two, Berger said.Bitten while boogie boardingThe second attack happened around 4:30 p.m. ET at New Smyrna Beach, about 100 miles south of the first. An 49-year-old man was bitten in the leg while boogie boarding, Volusia County Beach Safety said in a statement.The man was treated on the scene for lacerations to his right thigh, the statement said. He then drove himself to Bert Fish Medical Center for additional treatment.Berger say the shark that bit O'Rouke and believes it was a blacktip shark. The shark in the second attack was not seen by any witnesses. 1514

Who needs to keep a package of ready to eat macaroni and cheese from spoiling for three years at room temperature? If you're planning a trip to Mars, the answer could be yes. Researchers at Washington State University say they have found a way to triple the lifespan of ready to eat food. In the case of the macaroni and cheese, researchers believe they have found a way to keep macaroni from spoiling for three years. Previously the max lifespan the researchers could get for macaroni and cheese was 12 months using plastic. But using microwave-assisted thermal sterilization and adding a organic coating to metal oxide coating to the plastic can allow food to last three times longer. “We need a better barrier to keep oxygen away from the food and provide longer shelf-life similar to aluminum foil and plastic laminate pouches,” Shyam Sablani, a researcher with WSU, said in a statement. “We’ve always been thinking of developing a product that can go to Mars, but with technology that can also benefit consumers here on Earth.”While using metal oxide coating has been around for sometime, there was a flaw with the coating developing cracks to allow the food to be exposed to oxygen. “We are excited that an over-layer of organic coating on metal oxide helped protect against microscopic cracks,” Sablani said. “Multiple layers of metal oxide coating have also increased the barrier performance. Our research guided development of newer high barrier packaging.”Researchers like Sablani are hopeful the new technology could assist NASA in preserving food for a potential trip to Mars. With current technology, a trip to Mars could last at least two years. A one-way trip to Mars alone could last at least nine months. “NASA knows about our work, but we’re just now getting to the point where we can talk to them with a proven product,” Sablani said. “We hope to work out a way to test these products on the International Space Station in the future to show that the food is safe after long-term storage.”NASA has said its benchmark is for food to last five years. Sablani's team has food that is currently being aged to see if it is possible to store ready to eat meals for five years. Even if the technology might not be used for a trip to Mars, it could be of interest for the military. The packaging could be used for "meals ready to eat or MREs. 2366

Weak effort from @BurgerKing re: rebel whopper, wtf is the point bringing out a veg burger that's cooked with meat? I'm not precious about cross contamination but I draw the line at my food literally being cooked in meat juices. Get a new grill & change the mayo you cowards.— ?? Seeds in the Wasteland ??

WASHINGTON (AP) — The husband of a woman who died accidentally in an office of then-GOP Rep. Joe Scarborough two decades ago is demanding Twitter remove President Donald Trump's tweets suggesting Scarborough murdered her. Lori Klausutis died in Scarborough's Florida office in 2001.Timothy Klausutis asked Twitter CEO Jack Dorsey in a letter last week to delete Trump's tweets.Twitter says it's working to "more effectively address things like this going forward." Trump has feuded with Scarborough, who hosts MSNBC's "Morning Joe" show. Trump has tried to implicate Scarborough in the death even though Scarborough wasn't in Florida at the time. Scarborough has urged Trump to stop. Medical officials ruled Lori Klausutis fainted and hit her head. 760
