A world-first, non-invasive AI system can turn silent thoughts into text while only requiring users to wear a snug-fitting cap. The Australian researchers who developed the technology, called DeWave, tested the process using data from more than two dozen subjects. Participants read silently while wearing a cap that recorded their brain waves via electroencephalogram (EEG)…

GPS satellites support Earth measurements by relaying information to other satellites. Laser retroreflector arrays (LRAs) are improving this process, enhancing the accuracy of geodesy – the study of Earth’s shape and changes. LRAs enable precise distance measurements, essential for monitoring global phenomena like sea level rise and tectonic shifts. (Artist’s concept.) Credit: SciTechDaily.com Laser retroreflector…

Can-Am defines a side-by-side as an off-road vehicle with four or six wheels and bucket seats for passengers to sit, you guessed it, side-by-side. Enthusiasts know them as adventure machines or work tools, equally capable of exhilarating speeds and nimble efficiency. The brand’s newest offering is the Maverick R, designed for ripping through the dirt.…

From the ‘brains’ of NASA’s Europa Clipper to a lion’s mane jellyfish, the 29 images selected for the 2023 annual National Geographic Pictures of the Year issue commemorate extraordinary photographs taken all over the world.  For the issue’s cover image, patience is the theme. National Geographic photographer Kiliii Yuyan took the photo of a banded…

About three times a day, Rich Benoit gets a call to his auto shop, The Electrified Garage, from the owner of an older Tesla Model S whose car battery has begun to fail. The battery, which used to provide several hundred miles of range, might suddenly only last 50 miles on a single charge. These cars…

The Santa tracker presented by the North American Aerospace Defense Command (NORAD) dates to 1955. The joint US-Canadian military monitoring agency has continued its decades-long Christmas tradition of tracking Santa’s whereabouts, helping children around the globe find out when his reindeer-powered, present-filled sleigh is coming to town. … Continue Reading News Source: techxplore.com
