A 3D-printed battery that uses electrodes made from vegetable starch and carbon nanotubes could provide mobile devices with a more environmentally friendly, higher-capacity source of power, reports Tech Xplore. Engineers from the University of Glasgow developed a battery to make lithium-ion batteries capable of storing and delivering power more efficiently. The battery's design is outlined in a paper in the Journal of Power Sources.

It seems like it would be pretty cool to float around a space capsule, but six months of microgravity may aggravate strain by skewing astronauts' perception of the emotional state of their fellow travelers, according to a new study published in the journal Frontiers in Physiology.

An open-access quantum computing testbed is ready for the public, reports SciTechDaily. Scientists from Indiana University were the first team to use Sandia National Laboratories’ Quantum Scientific Computing Open User Testbed, or QSCOUT. Scientists from around the world can use QSCOUT for research that might not be possible at their home institutions.

Scientists at Ohio State University have developed technology to "retrain" cells to help repair damaged brain tissue, reports Medical Xpress. "We can rewrite the genetic code of skin cells so that they can become blood vessel cells," says study leader Daniel Gallego-Perez. "When they're deployed into the brain, they're able to grow new, healthy vascular tissue to restore normal blood supply and aid in the repair of damaged brain tissue."

NASA successfully completed a test on the Space Launch System (SLS), the most powerful rocket in existence, the BBC reports. Engines on the rocket's "core stage" were kept running for more than eight minutes, simulating the time it would take the SLS to go from the ground to space. NASA intends to use the SLS to send humans to the moon's surface for the first time since 1972.

IBM has developed an artificial intelligence-based system designed to engage in debates with humans, Tech Xplore reports. In their paper published in the journal Nature, IBM team members describe their system and how well it performed against human opponents. It listens to moderators and opponents and responds in a female voice. Having already impressed a human audience, you can expect to see Project Debater applying for the job of government lobbyist to push for loose...
Jupiter has long been known for the massive storm in its Great Red Spot, but astronomers claim that winds near the gas giant's poles make that storm look like a stiff breeze, CNET reports. The winds, found in the stratosphere under the bright auroras observed near the poles, have been measured at speeds of 1,450 kilometers per hour. That's roughly twice as fast as the speeds seen in the Great Red Spot and three times the power...
A U.S. teenager will spend three years in prison after pleading guilty to hacking high-profile Twitter accounts in a large-scale Bitcoin scam, the BBC reports. Graham Ivan Clark was 17 when he co-ordinated the scam, which hijacked the profiles of celebrities including Kim Kardashian West, Kanye West, Elon Musk, Bill Gates, and Barack Obama. Clark will be banned from using computers without permission and supervision from law enforcement. BIG Media predicts that once he gets out of...
