How the Earth's 'Hardiest Animal' Could Pave Way to Radiation-Resistant Humans, Life on Mars
Sep 22, 2016 03:51 AM EDT Researchers have discovered the secrets of tardigrades, the world's "hardiest animal," and how these water bears could survive extreme temperatures and radiation. Could humans one day survive X-ray and Mars? Water Bear's New Superpower According to a study published in the journal Nature Communications, a team of researchers from the University of Tokyo has found a specific kind of protein that protects the tardigrades' DNA. Tagged as "Dsup" (short for "damage depres..>> view original3D-Printed Acoustic Holograms Could Move Objects in Midair
The underwater acoustic hologram seen in the image projects a sound field towards a water surface. A paper boat is propelled and pushed along the track that is generated by the hologram. Credit: Kai Melde 3D-printed plastic blocks can now be turned into acoustic holograms that generate 3D shapes made of sound, which could function like sonic "tractor beams," according to a new study. This could lead to innovative ways to manipulate objects in midair without touching them, the researchers..>> view originalModern Technology Unlocks Secrets of a Damaged Biblical Scroll
The Dead Sea scrolls, those found at Qumran and elsewhere around the Dead Sea, contain versions quite similar to the Masoretic text but with many small differences. The text in the scroll found at the En-Gedi excavation site in Israel decades ago has none, according to Emanuel Tov, an expert on the Dead Sea scrolls at the Hebrew University of Jerusalem.

(NASA/JPL-Caltech/SSI) Saturn's moon Titan has been called the most Earthlike world found to date. It's the only other place in the solar system where stable liquid sits on the surface — seas of liquid methane flow into channels that have created magnificent canyons — and scientists have suggested that the icy world might be able to support some kind of alien life. Now researchers think they can add yet another "Earthlike" quality to Titan's extensive list: According to a study in Geophysic..>> view originalHow We Got Here: DNA Points to a Single Migration From Africa
Each team of researchers tackled different questions about our origins, such as how people spread across Africa and how others populated Australia. But all aimed to settle the controversial question of human expansion from Africa.In the 1980s, a group of paleoanthropologists and geneticists began championing a hypothesis that modern humans emerged only once from Africa, roughly 50,000 years ago. Skeletons and tools discovered at archaeological sites clearly indicated that modern humans lived af..>> view originalGoddard space center mission-critical for ISS astronauts
The International Space Station may bring to mind launch pads in Florida or control rooms in Houston, but humanity's longest continuously inhabited outpost in space also requires near-constant support from a small community just outside Washington, D.C. That's where, in Greenbelt, Maryland, resides NASA's Goddard Space Flight Center, home to the station's communications network and some of the capabilities that support scientific research on station. Like any NASA mission, particularly t..>> view originalClimate Change This Week: Megadroughts, Virtual Clean Power Plants, and More!

China launched a cache of Cabernet Sauvignon, Merlot, and Pinot Noir vines into space on the orbiting Tiangong-2 lab during this year’s Mid-Autumn Festival on September 15, in an experiment that hopes to yield a sturdier plant by exposing them to the harsh climates and radiation of space. According to DecanterChina.com, scientists hope the experiments will create a vine that is more drought, cold, and virus resistant making the vines more suitable for Chinese weather.
