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

Two Chicago police officers were killed Monday after being struck by a metro train, authorities said.Conrad Gary and Eduardo Marmolejo were responding to a shots fired call on the city's South Side when a passing train hit them, Chicago police Superintendent Eddie Johnson told reporters.The officers were searching an area near train tracks at 103rd Street and Cottage Grove Avenue when they were struck, Johnson said. The train had been traveling at 60 mph to 70 mph, he said."While doing the most dangerous thing any police officer can do, and that is to chase an individual with a gun, these brave young men were consumed with identifying a potential threat to their community and put the safety of others above their own," Johnson said.A suspect was ultimately taken into custody and a gun was recovered, Johnson said.Gary, 31, had been on the force 18 months. Marmolejo, 37, joined the department 2 1/2 years ago, Johnson said.The men, both fathers, lost their lives just a week before Christmas."This holiday will never be the same for those two families," Chicago Mayor Rahm Emanuel said. "And while our hearts are with them, we lost people who answered the call to make Chicago a better place. We go about our lives not thinking twice and we can do that because of the men and women in the Chicago police department."Johnson asked Chicago to pray for the families of the officers, and for the men and women of the officers' 5th district, "who, even tonight, would stop at nothing to safeguard their community," he said."This has been an immensely difficult year for the Chicago police department," Johnson said, "And especially for the men and women of the 5th district where they have faced tragedy after tragedy this year." 1746

Virtual reality is big in the gaming word. But now, the technology is being used to help better understand Alzheimer’s disease. According to the World Health Organization, 50 million people around the world suffer from Alzheimer’s, and that number is growing rapidly. By 2050, it’s expected to double. "It can be challenging, right? Because there is no cure,” says Molly Fogel, an educator at the Alzheimer’s Foundation of America.Fogel is part of the crusade to help people better understand what it’s like living with this illness. That's where virtual reality comes in. “Virtual reality helps you become part of Harry's morning,” Fogel explains of the program. “You will be in his shoes. “It's a 3 minute and 12 second experience.” The video goes through the first part of Harry's day. He has Alzheimer’s.During the VR experience, users will experience things like blurry vision, hallucinations, confusion and disorganization. “Our hope is that we can help people through a really cool technology,” Fogel says. The device launched this year as a tool to help care givers, and even family members, empathize and understand the disease. “Most likely you know somebody or will know somebody living with this illness, Fogel says.“As we can better understand Alzheimer’s disease--destigmatize Alzheimer’s disease--we can be better friends, community members, healthcare professionals, and help the person live with this illness, versus suffer with the illness.” 1474

WASHINGTON, D.C. -- United States officials are braced for Iran to respond to the killing of its most powerful general. They've warned ships across Mideast waterways crucial to global energy supplies about the “possibility of Iranian action" against them. They're noting heightened levels of military readiness in the country and are preparing for a possible attempt on the life of an American military commander. The U.S. is reinforcing its positions in the region. President Donald Trump ordered the Jan. 2 strike against Gen. Qassem Soleimani after the death of an American contractor in Iraq. U.S. officials believe the next steps by America's longtime foe will determine the ultimate course of the latest crisis. Iran has vowed revenge. 753
