This mouse was grown from its mother's skin cells
K. Hayashi/Kyushu University For the first time, researchers have grown eggs entirely in a lab dish. Skin-producing cells called fibroblasts from the tip of an adult mouse’s tail have been reprogrammed to make eggs, Japanese researchers report online October 17 in Nature. Those eggs were fertilized and grew into six healthy mice. The accomplishment could make it possible to study the formation of gametes — eggs and sperm — a mysterious process that takes place inside fetus..>> view originalOrbital ATK's Antares Rocket Returns to Flight with Gorgeous Night Cargo Launch

NASA's Juno mission managers have postponed the burn of the main rocket, which was initially scheduled for Oct. 19. The burn, dubbed period reduction maneuver, is aimed at reducing Juno's orbital period from 53.4 days to only 14. The team designing the mission has decided to delay the period reduction maneuver in order to analyze the performance of a set of valves that are part of Juno's fuel pressurization system. They also limited the use of science instruments for Juno's burn. However, since..>> view originalEuropean Probe to Attempt Daring Mars Landing Wednesday: What to Expect
Europe is on track to achieve an epic Mars landing on Wednesday (Oct. 19) — that is, as long as its spacecraft can survive supersonic speeds, iron-melting heat and a tightly choreographed set of final maneuvers. The landing capsule, named Schiaparelli, is scheduled to touch down on the Red Planet's surface tomorrow (Oct. 19) as part of ExoMars 2016, a joint mission by the European Space Agency (ESA) and Russia's Roscosmos space agency.

China's space agency launched two astronauts, or taikonauts, Monday morning into low Earth orbit aboard its Shenzhou 11 spacecraft. If all goes according to plan, in two days they will dock with China’s Tiangong 2 space station, where the taikonauts will stay for 30 days to test its habitability and to carry out medical and scientific experiments.Monday’s launch marked the sixth time China has sent taikonauts into space, and the beginning of the country’s longest crewed mission yet as it builds..>> view originalUniverse: More Galaxies than Thought - Sci

This is not an election year in which it is easy to get attention, unless your name rhymes with Gump. Nevertheless, it's worth taking note of a colorful, contentious, and counterintuitive political drama playing out in the top left corner of the country. It’s a fight happening within the left, and like a great many such fights in US politics these days, it reveals sharp differences over how to make progress in the face of Republican intransigence. In this case, the subject is climate change pol..>> view originalThe amazing sweating robot
At 5 1/2 feet tall, its face fixed between a grin and a grimace, the humanoid robot Kengoro is something of a synthetic Arnold Schwarzenegger. That is not to say the machine, created by the University of Tokyo’s JSK laboratory, is a recursive time-traveling assassin. Rather, Kengoro is a sweaty beefcake among metal bipeds. The average two-legged machine does not have Kengoro’s stamina. For a svelte robot, Kengoro is strong, powered by 108 motors. Thanks to this large number of motors plus a u..>> view original
