Historic floods across the Midwest have left three dead, prompted mass evacuations, and drowned cities. The floods aren’t isolated incidents, however: Two giant waves of water are rolling down from the country's far-northern middle expanse. One wave is following the path of the Missouri River toward the Mississippi River, carrying with it big chunks of ice. The second wave is taking a similar path down the Mississippi River from Minnesota. Both are the result of a long winter of heavy snowfall in Minnesota and the Dakotas followed by a short, sharp melt. Both floods are more or less each one giant wave traveling at the speeds of their rivers, said Darone Jones, director of the Water Prediction Operations Division (WPOD) at the National Weather Service’s National Water Center (NWC) in Alabama. The North Dakota wave traveled down the Missouri River to Nebraska and yesterday (March 18) reached northwestern Missouri. After passing Kansas City it will turn left, following the … [Read more...] about What’s Behind the Massive Midwestern Floods: 2 Giant Waves of Water

The ancient supercontinent of Rodinia turned inside out as the Earth swallowed its own ocean some 700 million years ago, new research suggests. Rodinia was a supercontinent that preceded the more famous Pangea, which existed between 320 million and 170 million years ago. In a new study, scientists led by Zheng-Xiang Li of Curtin University in Perth, Australia, argue that supercontinents and their superoceans form and break up in alternating cycles that sometimes preserve the ocean crust and sometimes recycle it back into Earth's interior. "We suggest that the Earth's mantle structure only gets completely reorganised every second supercontinent [or every other cycle] through the regeneration of a new superocean and a new ring of fire," Li wrote in an email to Live Science. The "Ring of Fire" is a chain of subduction zones around the Pacific, where the crust of the ocean grinds underneath the continents. Volcanoes and earthquakes are frequent around the Ring of Fire, lending it its … [Read more...] about Earth Once Swallowed Its Own Superocean. Could It Happen Again?
Nearly 2,400 years ago, the philosopher Plato described Atlantis as a mighty state that possessed 10,000 chariots, advanced technologies, vast numbers of elephants and bulls, and a series of complex canals. And now, in a new documentary, a U.K.-based group claims to have discovered the ruins of this once-flourishing society on what is now the Atlantic coast of Spain. But one archaeologist said that the ruins likely belong to another ancient culture, and several researchers interviewed by Live Science could barely contain their exasperation when they heard the news of yet another Atlantis discovery. (People have made dozens of such claims over the years, locating the legendary society in Antarctica, Bolivia, Turkey, Germany, Malta, the Caribbean and elsewhere.) "Bless their hearts — if they're correct about this, that would be awesome," said Ken Feder, a professor of anthropology at Central Connecticut State University. "But here's my problem: As an archaeologist, I know that I … [Read more...] about Atlantis Found (Again)! And Exasperated Scientists (Again) Raise Their Eyebrows

Space is a dangerous place for humans: Microgravity sets our fluids wandering and weakens muscles, radiation tears through DNA and the harsh vacuum outside is an ever-present threat. But for materials that show incredible strength, transmit information with barely any loss, form enormous crystals or even grow into organs, the harshness of space can be the perfect construction zone. As the cost of spaceflight goes down, more of these materials may become cost-effective to make or study in space. And soon, more and more people might be carrying around objects built off the planet. [Top 10 Strangest Things in Space] "We generally make things by subjecting them to a different environment," said Andrew Rush, president and CEO of Made In Space, an in-space manufacturing company. "We make food by cooking it in fire, heating it up and causing chemical reactions. We make steel by heating things up at high temperature and maybe, depending on the steel, [in a] high-pressure environment. … [Read more...] about Making Stuff in Space: Off-Earth Manufacturing Is Just Getting Started
