Universal computer memory that’s both super-fast and energy efficient is one step closer to reality after scientists built an “extremely” stable prototype using a completely new material. The new material, dubbed “GST467,” which contains germanium, antimony and terbium, was used as one repeating layer in a stacked-layer structure, known as a superlattice, and could pave … Read more
For the first time, scientists have generated functional human brain tissue using a 3D printer. Scientists printed the tissue to be less than 0.01 inch (0.02 centimeter) thick, and it contains both nerve cells and supporting cells called glia. All of these cells can communicate with one another and form networks, as they would in … Read more
Very soon, a robot surgeon may begin its practice in orbit — and though it won’t quite be a metallic, humanoid machine wearing a white coat and holding a scalpel, its mission is fascinating nonetheless. On Tuesday (Jan. 30), scientists sent a slew of innovative experiments to the International Space Station (ISS) via Northrop Grumman’s … Read more
A malicious technology can trick self-driving cars into “hallucinating” phantom vehicles and veering dangerously off-course to get out of their way, researchers have discovered. The new hack, dubbed “MadRadar,” can also hide real cars from on-vehicle radar sensors and fool a self-driving car into thinking a real car has jerked off course. The scientists reported … Read more
Chinese scientists have built a nuclear battery that can produce power for up to 50 years without being recharged. The technology, which contains a radioactive isotope, or version of nickel, as its power source, will be the first of its kind available for general purchase, Betavolt representatives said on Jan. 8 in a translated statement. … Read more
Currently, it is impossible to accurately predict when and where an earthquake might strike. But scientists now believe that Global Positioning System (GPS) data could help spot early warning signs two hours before a big quake strikes. Earthquakes occur when the slabs of slow-moving rocks just under Earth’s surface — known as tectonic plates — … Read more
In science fiction films, nothing raises tension quite like the good guys’ spaceship getting caught in an invisible tractor beam that allows the baddies to slowly reel them in. But what was once only a sci-fi staple could soon become a reality. Scientists are developing a real-life tractor beam, dubbed an electrostatic tractor. This tractor … Read more
Quantum computers could beat classical ones at answering practical questions within two years, a new experiment from IBM computers shows. The demonstration hints that true quantum supremacy, in which quantum computers overtake classical digital ones, could be here surprisingly soon. “These machines are coming,” Sabrina Maniscalco, CEO of Helsinki-based quantum-computing startup Algorithmiq, told Nature News. … Read more
If intelligent aliens are searching for other advanced lifeforms in the galaxy, our cell phone towers could be the beacons that give Earthlings away. New research suggests that advanced aliens in nearby star systems could probably already detect radio signals from cell phone towers. And as these signals become more powerful, humanity’s calling card will … Read more
Geologists in northern Guatemala have discovered a massive Maya site that stretches approximately 650 square miles (1,700 square kilometers) and dates to the Middle and Late Preclassic period (roughly 1000 B.C. to 250 B.C.). The findings were the result of an aerial survey that researchers conducted via airplane using lidar (light detection and ranging), in … Read more
