When people think of pandemics, they might think of a severe disease. But it turns out, pandemics have nothing to do with severity – and everything to do with location.By definition, a pandemic is the global spread of a disease that impacts a large number of people.Think of pandemics as being at the top of a three-tier system of classifying infectious disease.Outbreaks are at the base. They happen when cases of a disease suddenly surge past expectations. The flu is an example of an outbreak doctors expect to see every year.On the second level – epidemics. They happen when the disease involved in the outbreak spreads quickly to a lot of people in a short period of time. They can be local or regional.You’ll find pandemics on the third tier. They’re basically epidemics, but on a global level. That typically means more infections and more deaths.Pandemics are often the result of a new virus or new strain of virus.According to the Association for Professionals in Infection Control and Epidemiology, it says new diseases spread fast because people don’t have immunity.The APIC says pandemics do damage beyond health, saying they also often cause disruption, economic trouble, and general hardship.So, what does this mean for COVID-19? There’s no specific infection or death rate that triggers a pandemic designation. And U.S. leaders recently said the word is largely up to interpretation. For that reason, different health organizations may declare COVID-19 a pandemic at different times.Experts say declaring a pandemic can help get the world on board with finding – and funding – a solution. 1615

WASHINGTON, D.C. – After the U.S. Senate voted on Wednesday to approve the House’s coronavirus response bill, President Donald Trump signed the bill Wednesday night.The bill includes free coronavirus testing, expanded family and medical leave for some, paid emergency sick leave for some, unemployment benefits, food assistance, and protections for health care workers.The Senate passed the bill 90-8. The following senators voted against the bill: Marsha Blackburn, Jim Inhofe, Ron Johnson, James Lankford, Mike Lee, Rand Paul, Ben Sasse, and Tim Scott. Senators Cory Gardner and Rick Scott didn’t vote, as both are under a self-quarantine as a precaution.The bill authorizes 0 million to provide access to nutritious foods to low-income pregnant women or mothers with young children who lose their jobs or are laid off due to the COVID-19 emergency. The bill also allocates 0 million to assist local food banks to meet increased demand for low-income Americans during the emergency. Of the total, 0 million is for the purchase of nutritious foods and 0 million is to support the storage and distribution of the foods. 1146

Uber is blowing through billions of dollars, but CEO Dara Khosrowshahi is undeterred.In an interview with CNN correspondent Christiane Amanpour that will air Wednesday, Khosrowshahi defended Uber's business model, which involves the company investing heavily in promotions to entice customers to its on-demand ride and meal-delivery offerings."The model is absolutely sustainable," Khosrowshahi said. "The business, for example, is still growing 30-plus percent on a global basis. And anytime you have a business that has the kind of market size of trillions of dollars in terms of transportation and food and global commerce, it makes sense for a company to invest."Uber lost .2 billion in the three months ending in June, its 742

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
