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

Scientists Have Identified the Origin of an Extraordinarily Powerful Outer-Space Radio Wave

wired.com Jorge Garay 2025-10-26 16:49:17

The Earth is constantly receiving space signals that contain vital information about extremely energetic phenomena. Among the most peculiar are brief pulses of extremely high-energy radio waves, known as fast radio bursts (FRB). Astronomers compare them to a powerful lighthouse that shines for milliseconds in the middle of a rough, distant sea. Detecting one of these signals is an achievement in itself, but identifying its origin and understanding the nature of its source remains one of the grea

Scientists Propose a Smarter Way to Hunt for Alien Radio Signals

gizmodo.com George Dvorsky 2025-10-28 23:00:31

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. New research suggests refining our search parameters by using our own broadcasts into deep space as a helpful guide. Research published earlier this week in Astrophysical Journal Letters suggests we search for alien signals by studying how we beam strong, directed transmissions during two-way communication with our de

An inner-speech decoder reveals some mental privacy issues

arstechnica.com Unknown 2025-10-28 22:00:57

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. To go around it, researchers at the Stanford University built a BCI that could decode inner speech—the kind we engage in silent reading and use for al

The 1090 Megahertz Riddle: A Guide to Decoding Mode S and ADS-B Signals

In the last twenty years, aircraft surveillance has moved from controller-based interrogation to automatic broadcast. The Automatic Dependent Surveillance-Broadcast (ADS-B) is one of the most common methods for aircraft to report their state information like identity, position, and speed. Like other Mode S communications, ADS-B makes use of the 1090 megahertz transponder to transmit data. The protocol for ADS-B is open, and low-cost receivers can easily be used to intercept its signals. Many rec

Meta’s Body-Reading Wristband Is Getting a Lot More Sophisticated

gizmodo.com James Pero 2025-12-27 20:54:55

Meta is back to teasing its futuristic body-reading wristband, and this time around, it’s getting a little more specific with what the wearable can do. In short? It looks like all that high-level research is paying off. Meta published a new research paper in the journal Nature, showcasing progress on its sEMG-RD wearable, a device that was most recently shown at its Connect conference in 2024. That device, using sensors on a wristband, can read electrical signals in your muscles and translate th

Meta researchers are developing a gesture-controlled wristband that can interact with a computer

Meta researchers are developing a wristband that lets people control a computer using hand gestures. This includes moving a cursor, opening apps, and sending messages by writing in the air as if using a pencil. Meta’s wristband employs a technique called surface electromyography (sEMG), which detects electrical signals generated by muscle activity to interpret user movements, as explained in a research paper published in the journal Nature. These signals can sense a person’s intended actions, e

Aliens Can Detect Earth’s Airports From 200 Light-Years Away

Humans might not know of any intelligent beings beyond Earth, but if they exist, they might already know about us. New research shows that radar systems at commercial and military airports are inadvertently announcing our presence to any aliens with the ability to listen. Preliminary results from a study led by Ramiro Caisse Saide, an astrophysics PhD candidate at the University of Manchester, suggest extraterrestrials up to 200 light-years away could theoretically detect electromagnetic signal

In the animal kingdom, there is incredible variation in visual perception. What an animal sees depends on the structure of its retina and its neural visual processing system. Most insects can see ultraviolet, blue and green light, but there is wide variety among arthropods; mantis shrimp eyes have up to 12 different channels of color, revealing the ultraviolet spectrum and polarized light. The ancestor of living vertebrates could likely detect red, purple, blue and green — an ability that was ma

Cell Towers Can Double as Cheap Radar Systems for Ports and Harbors (2014)

How do you see ships without a pricey radar system? The question has troubled seaports around the world as they work to improve security. Without radar installations, it can be hard for port employees to detect small ships like those employed by pirates or by the terrorists who attacked the USS Cole in 2000. A team of researchers in Germany can now offer security teams a new option, though: putting existing cellular towers to work as quick and dirty radar systems. Developed at the Fraunhofer In

Nonprofit Creative Commons, which spearheaded the licensing movement that allows creators to share their works while retaining copyright, is now preparing for the AI era. On Wednesday, the organization announced the launch of a new project, CC signals, which will allow dataset holders to detail how their content can or cannot be reused by machines, as in the case of training AI models.

Scientists in Antarctica Detect Deep-Earth Signals That Defy Known Physics

A balloon-borne experiment over Antarctica, designed to detect cosmic radio waves, has instead picked up bizarre signals that appear to be coming from deep within the ice. These signals challenge our current understanding of particle physics, scientists say. The Antarctic Impulsive Transient Antenna (ANITA) experiment consists of radio antennas flown on NASA balloons 19 to 24 miles (30 to 39 kilometers) over the surface of Antarctica.
