Amazon is banning its third-party merchants from using FedEx’s ground service to deliver to Prime members, suggesting that it thinks the service is too slow to get packages to their destinations in time for Christmas. The temporary ban will block those companies from using FedEx Ground service, although they can still use pricier FedEx Express shipping for Prime shipments. More than half of the items sold on Amazon.com come from third-party sellers, who post their goods for sale on Amazon’s online marketplace. News of the ban was first 554

America's fertility rate and the number of births nationwide are continuing to decline.The number of births for the United States last year dropped to its lowest in about three decades, according to provisional data in a new report from the National Center for Health Statistics at the US Centers for Disease Control and Prevention."Even though the number of births we've seen in 2018 is the lowest that we've seen in 32 years, the total fertility rate is at a record low," said Brady Hamilton, a 509

Although scientists study space every day, what’s been difficult learning more about "deep space." But there's one company helping NASA and the U.S. Air Force go where no satellite has gone before."Deep space" is well outside the Earth's atmosphere, lying beyond the Earth-moon solar system. It's also known as "interstellar space." Deep space is a mystery to a lot of scientists. NASA's Voyager spacecraft that was launched in 2011 reached the edge of our solar system.Many scientists are wanting to make their way past Jupiter to learn even more, but there are limitations in the space engine technology today. A company called Roccor, based in Longmont, Colorado, is doing their best to change that.“We are just getting in a contract with NASA to do solar sailing where we are going to leave earths orbital realm and go much farther away,” said Bruce Davis, who works for Roccor.Davis and his team are working on a project called the "solar cruiser."They created what’s called a "solar sail." It essentially gets attached to a spacecraft and acts as a propeller, ultimately upping its performance by pushing it farther into deep space.“We are capturing whatever is coming off the sun — that’s radiation, that’s photons — we call it a collective pressure," Davis said. "That’s what we are trying to grab to give ourselves propulsion.”When the sail opens up, it’s as big as an office building. Right now, they are only in creation mode, but they hope to have it done soon. 1490

Amazon, facing increased competition from traditional retailers, has expanded free next-day delivery for more than ten million products for Prime members.Starting Monday, the offer is available "coast to coast" in the United States with no minimum purchase, the company announced."The most popular one-day items range from books, beauty and baby wipes to devices, dish detergent and doggie bags," the company said in a press release. Amazon said it "will keep adding more selection and expanding our delivery areas to ensure Prime members get their products faster than ever."Amazon has for years set the bar for online shopping convenience by offering free two-day shipping, and other retail giants have raced to catch up.The company in April announced it would spend 0 million to cut that delivery window in half.Amazon has built up a massive shipping network in the United States that includes more than 100 fulfillment centers, 100 delivery stations, and a fleet of Amazon Air cargo planes.Prime customers, who pay 9 a year for a membership, can already get free same-day shipping in some areas. And Amazon's Prime Now platform, available in most major cities, offers delivery within hours for certain products.Not everyone is pleased with Amazon's plans for speedier shipping.The increased workload that comes with fulfilling orders in one day could be dangerous for Amazon's warehouse employees, according to Stuart Appelbaum, president of the Retail, Wholesale and Department Store Union. An Amazon executive accused him of spreading "falsehoods."Stock prices of traditional retailers, including Walmart and Target, took a hit when Amazon promised to step up its shipping game. Wall Street fears Amazon's competitors will further squeeze their already tight bottom lines trying to speed up their own deliveries.Walmart took the plunge anyway: Last month the company said it will roll out next-day delivery in 75% of the United States this year, a move that could cost as much as 5 million, according to one analyst estimate. Walmart said it can handle the load with its own network of fulfillment centers and 4,700 US stores. 2153
