This Wearable Isn't Telepathic, but It Knows What You Want to Say

Telepathy is, until proven otherwise, still science fiction. But a new wearable announced this week aims to bring the world closer to silent communication, though it's more about using brain signals than the X-Men superpower. Alterego, developed by the MIT Media Lab, is a peripheral neural interface that allows us to converse with machines, artificial intelligence assistants and humans, without using our voice or externally observable movements. We first saw the Alterego as a prototype in 2018

Think family photos, sweet messages, important documents, or anything else you don’t want to lose forever.

Eero’s Signal is a cellular safety net for your Wi-Fi network

Last-Minute Software Patch Saves Jupiter Probe Ahead of Critical Venus Flyby

An exceptionally heavy interplanetary probe is on an eight-year journey to Jupiter, using the gravity of Earth and Venus to propel it on its path toward the gas giant. Just weeks before its scheduled flyby of Venus, the European Space Agency’s JUICE mission went silent, threatening its ability to perform the planetary encounter.

Astronomers Revisit the Mysterious Wow! Signal—and Find a Big Surprise

Nearly 50 years ago, astronomers searching the cosmos for evidence of intelligent extraterrestrial life detected a strong radio signal emanating from deep space. Today, scientists still aren’t sure where—or what—the Wow! Signal came from. It remains one of the most perplexing phenomena in the history of radio astronomy.

The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look.

An inner-speech decoder reveals some mental privacy issues

Most experimental brain-computer interfaces (BCIs) that have been used for synthesizing human speech have been implanted in the areas of the brain that translate the intention to speak into the muscle actions that produce it. A patient has to physically attempt to speak to make these implants work, which is tiresome for severely paralyzed people.

Candle Flame Oscillations as a Clock

Todays candles have been optimized for millenia not to flicker. But it turns out when we bundle three of them together, we can undo all of these optimizations and the resulting triplet will start to naturally oscillate. A fascinating fact is that the oscillation frequency is rather stable at ~9.9Hz as it mainly depends on gravity and diameter of the flame. We use a rather unusual approach based on a wire suspended in the flame, that can sense capacitance changes caused by the ionized gases in t
