Earbud translators will bring us closer: The Future IRL
The moment Google Pixel Buds were used earlier this month to demonstrate real time translation from Swedish to English, people started freaking out about potential use cases for this kind of technology. But the thing is, Google isn't the only company taking this on.
Researchers can use the size of your heart to unlock a PC
Most biometric security has one inconvenience: you have to take an active step to sign in, whether it's putting your finger on a pad or staring at sensors. Wouldn't it be nice if simply being near your device was enough? It might happen. Researchers have created a computer authentication system that uses your heart's shape and size to sign in. It uses low-level Doppler radar to continuously scan your heart's dimensions, granting access so long as you're in the right place. In other words, Cindy-Lou Who couldn't hijack the Grinch's PC when he steps away for a coffee break.
Remembering the first 'photo' of a black hole
Black holes are so outlandish that the scientists who first thought them up figured they couldn't possibly exist in reality. They form from massive, collapsed stars and are so dense that nothing can escape their gravitational pull, including light. Black holes mess with spacetime so badly that scientists have long wondered: How do these things look, exactly? We may be on the cusp of seeing one thanks to the Event Horizon Telescope, but back in 1979, Jean-Pierre Luminet created the first "image" using nothing but an early computer, lots of math and India ink.
These smart earbuds are volume knobs for the real world
Your choices for filtering the sounds around you are typically quite limited: you either have to drown it out (such as through earplugs or headphones) or let all the annoyances in. Doppler Labs might soon have a way to be more selective, though. Its crowdfunded Here Active Listening earbuds are meant solely to control what you hear in the real world. You not only decide how much gets through, but how it gets through. There's an equalizer if you want to tweak certain sound frequencies (toning down the bass at a badly-mixed concert, for example), and there are preset filters designed to tune out common noises or add effects. Want to silence the background hum of your office without completely shutting out your coworkers? You probably can.
