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

Walmart, America's largest retailer, said Friday it will stop selling e-cigarettes as the number of deaths tied to vaping grows."Given the growing federal, state and local regulatory complexity and uncertainty regarding e-cigarettes, we plan to discontinue the sale of electronic nicotine delivery products at all Walmart and Sam's Club U.S. locations," the company said in a statement. "We will complete our exit after selling through current inventory."The CDC said yesterday that 495

Video games allow us to let go and play in someone else's world for a while.At the Smithsonian American Art Museum's recent video game convention, one game is getting a lot of attention for combining beautiful graphics with the ugliness of war. The game is called Brukel and it tells the story of World War II through the eyes of someone who lived it.“This whole thing is obviously a labor of love,” one gamer said of Brukel. “It’s obviously very personal to the creator.”The creator is Bob DeSchutter, an award-winning video game developer and a college professor at Miami University. “In the game, you go in there and you have your cellphone with you,” he says. “You can take pictures of everything, and if you take pictures of an object, you hear my grandma talk about it.”De Schutter traveled to Belgium to have his 93-year-old grandmother, Bie Verlinden, narrate this video game. Verlinden is also the game’s hero, and players shoot a camera instead of a gun. It took De Schutter five years of coding to create Brukel, and the finished product has both his critics' and grandma’s approval.“She’s like, ‘Oh, wow! This looks exactly the way it was,’” De Schutter says about his grandmother’s reaction to the video game. “I’m obviously very happy about that.”The game is also gaining positive attention among parents, who say they are happy to have their children play this game. “It’s a different spin from Fortnite, from Madden and all the other games that they play,” says parent Shaunice Morris. “Now, they’re able to play the game and have fun playing the video game, but also learn while in the process.”It's learning that includes life lessons that span countries and cultures, coming from a woman who lived through war and is now able to share her stories across generations through gaming. 1812
