JACKSON, Miss. — Days and days of heavy rain have forced authorities managing dams in Mississippi and Tennessee to release more water, worsening the flooding for people living downstream. Dramatic video posted by a Tennessee fire department showed the impact: Two houses tumbled down a bluff over the Tennessee River, while many others have been swamped to their rooftops. Entire neighborhoods have disappeared in muddy water below the Tennessee Valley Authority's Pickwick Reservoir. In Mississippi, people in and around the capital of Jackson are bracing for more flooding as the rain-swollen Pearl River is expected to crest on Monday. 651

Iron Man is coming to life! Well, maybe not the superhero himself, but his iconic suit is being recreated. A group of engineering students and the Discovery Channel teamed up to make a real-life Iron Man suit.Adam Savage, host of Savage Builds on the Discovery Channel, recruited Craig Brice, a professor from Colorado’s School of Mines, who is known for his teachings in 3D metal printing.Jesse Adamczyk is one of 14 students selected to work on the Iron Man Project, and he was excited to be working with Savage.“We got to start working alongside Adam Savage and started fitting pieces around him and working right next to him. Right next to this legend,” Adamczyk says.Marvel Studios sent the students computer-generated imagery from the hit movie. Each piece of the 250-piece suit of armor was created from 3D printers and made out of titanium. They poured titanium powder into the printer and used a laser to cut out each piece.“The hands of the suit were very challenging,” Adamczyk says. “The hands, each had 30 parts, and the actual hand was about this thick of material.”This creation was such a phenomenal undertaking, because until recently, 3D printed metal parts were used only in military aircrafts and commercial vehicles.After three months of work, the team even impressed themselves with their capabilities. Adamczyk says the final product was incredible. And if the suit wasn’t cool enough, the group even put jet packs on the arms to make it fly, just like the one in the movie. 1509

KEARNEY, Mo. — The Kearney School District superintendent said threats a student made at the Missouri middle school were not credible. Bill Nicely said, in accordance with district protocol, his office did not notify parents of the investigation because it was found to be non-credible.“If it's a non-credible threat, we don't always notify parents every time that happens. I don't think parents would want the undue worry,” Nicely said. “We make that judgment call as we go forward.”Nicely added he has learned from this situation and those lessons will influence how he communicates with families in the future. He apologized to families who felt left in the dark.Friday, parents at Kearney Middle School learned police were 739
