At every CES I’ve ever been to, there’s been one or two gadgets promising to boost your mental health. In recent years, the number of companies making forays into this space has grown, and will likely continue to do so in the future. Could it be, much like the number of people wearing heart-monitoring wearables today, everyone will be strapping an EEG to their skulls a decade or so down the line? It’s more likely than you think, so it’s worth asking what these devices are good for, what benefit they could bring, and where does the science end and the hype begin.

An Electroencephalogram (EEG) is a clinical tool to monitor the electrical activity of our brains. Put very simply, our minds are constantly moving ions around, and when they reach the scalp, it’s possible to measure those ions. By placing electrodes on the scalp, you can record the changes in voltages pushed out by our brains more or less in real time. These voltages are commonly grouped into categories, which are often described as brain waves. Each one represents a different state of mind: Gamma (hard thinking), Beta (anxious or active), Alpha (relaxed), Theta (creative, or dreaming) and Delta (asleep). 

Professor Karl Friston at University College London is one of the world’s most influential neuroscientists and an expert in brain imaging. He explained that these technologies can be used to diagnose issues both in the structure and function of the brain. And while there are many technologies which can look at how our brains work, “we’re a long way away from understanding the brain like we understand the heart.” Broadly speaking, EEGs are a fairly simple tool for looking at how our minds work, but they have one benefit over more complex methods such as fMRI (functional Magnetic Resonance Imaging), since they work in real time.

Consumer-use EEGs are nothing new — in 2011 I tested the Zeo Mobile, a small device which you stuck to your forehead and wore overnight. It monitored how well you slept and sounded an alarm when you were at the top of a sleep cycle, so you woke up pretty easily. It worked well but with one downside: It’s hard to sleep with a hard plastic puck stuck to your forehead.

EEGs are more recently used as part of brain computer interfaces, or for neurofeedback tools to help you calibrate the quality of your meditation. InteraXon, for instance, makes the Muse headbands which will monitor your brain waves, telling you when you shift states. Last year, EEG startup Neurable partnered with Master & Dynamic to launch the MW75S Neuro, a pair of high-end headphones designed to track your focus levels. When your attention starts to wane, the system will alert you, advising you to take a rest with the hope of alleviating burnout.

At CES this year, Neurable announced a partnership with HP’s gaming arm HyperX to produce EEG headsets with specific benefits for gamers. As gamers are looking for any way to improve their performance, the company has developed algorithms and training programs to help. You might already know that being in a place of high stress isn’t great for your concentration and focus. Consequently, Neurable research scientist Dr. Alicia Howell-Munson walked me through a system that encourages you to reach a state of calm focus with demonstrable improvements in reaction time and accuracy. It’s a system that was initially designed in partnership with Singapore’s Air Force to help ensure pilots remain in a state of calm focus. 

I sat through this demo myself, initially testing my skills in Aimlabs (a tool people use to test their reflexes) where my accuracy and reaction times were measured. Then, while wearing Neurable’s headset, I had to practice focusing my attention on a galaxy of dots, the greater my focus, the slower and closer together the dots got. That wasn’t an easy process, and it took me nearly five minutes to reach the point where I could push all of the dots to coalesce into a single point on the screen. But, when I had, I retook the shooting gallery, and saw dramatic spikes in my performance. My accuracy increased from 91.3 to 99.1 percent, while my reaction time fell from 623ms to 532ms.

Neurable believes that its systems, which are designed to integrate with any manufacturer’s gear, has the potential to dramatically increase a person’s brain health and productivity. For instance, by taking a break when a person’s focus started to wane, they were able to bounce back and function for far longer than if they’d simply pushed harder. Similarly, the company can advise on your cognitive speed and brain age and guide you toward making healthy choices. The company says that this isn’t just about wellness, either, as being able to identify loss of focus is vital, for instance, to help reduce auto accidents when truck drivers feel fatigued. 

Co-founder Adam Molnar explained that the benefits of this technology compound over time, so the more practice a user has in finding that mental state of calm focus, the easier it will be to maintain it for longer. CEO Ramses Alcaide added the company’s aim is to enable people to visualize the often invisible symptoms of cognitive stress to ensure they’re looking after themselves. He added that one thing that separates Neurable from other companies is that it’s looking at far finer-grain detail from its EEG data.

There are plenty of companies at CES that are using EEGs for more specific goals, such as MyWaves. It uses an EEG as part of its broader offering to use sound patterns to make it easier to go to sleep. It sells you a pricey forehead-worn EEG which you wear for a few nights over the course of a year. From there, the system produces a half hour audio file that will mirror the pattern of your delta brainwaves. It claims that, if you listen to the track before you go to bed, the experience of hearing your delta waves will help you fall asleep faster and experience more REM sleep.

And there are plenty of companies which are building EEGs for you to wear to keep an eye on your mental health. Brain-Life, for instance, showed off an early prototype of Focus+, a headband EEG with a companion app that can offer feedback on your cognitive load. It can also tell you how long you can sustain your attention and how well your mind relaxes and recovers. The company didn’t have details on when the hardware would be available or how much it cost, as it’s still early days.

There is broad potential to use an EEG as a brain computer interface, such as the one worked on by Braineulink. That company has combined an EEG with an AR headset to enable people to interact with the world just with their brains. For instance, in a demonstration in the show floor at CES, I was able to turn a light on and off by “focusing” on it, although it’s hard to know how useful that would be in, for instance, creating an assistive device for folks with limited mobility. Like Brain-Life, it’s early days, and so there’s no product that we can point to, but it’s clear we’re going to see more startups looking to enter this world.

As EEGs become more commonplace, it’s likely they’ll be packaged in smaller devices which fit more seamlessly into our lives. One such example is NAOX, a French startup which has built a wearable, clinical-grade EEG into a pair of earbuds for the sort of longitudinal testing required to diagnose conditions like epilepsy. But the company is also planning on incorporating the technology into a pair of true wireless earbuds.These headphones won’t be arriving until the end of 2026, but Naox says the tech is small enough that it can be integrated with other companies earbuds. Consequently, it’s certainly plausible we could see plenty of earbuds that will keep an eye on our brain health as a side hustle. 

Daniel Cooper for Engadget

NAOX was co-founded by Dr. Michel Le Van Quyen who, at a talk in London in December 2025, talked about the rationale for creating an in-ear ECG. Essentially, he was looking to build a brain equivalent to the Apple Watch’s continuous heart rate monitoring (and ECG). I was curious about the science behind an ear-mounted EEG given they commonly use the scalp. Professor Friston said that an ear-mounted EEG is potentially more useful as “you can get slightly closer to the sources of activity.” And that it makes a lot of sense for a consumer-grade EEG to be added to wireless earbuds given their utility in practices like meditation.

One downside of the proliferation of wearable EEGs is that it could lead users to jump to the wrong conclusions about their mental health. For instance, if someone is to be diagnosed with a condition such as epilepsy, they need to undergo a 24-hour perambulatory EEG. As Professor Friston explained, the recording of that 24 hour EEG would be “carefully scrutinized by experts who are able to run a differential diagnosis ... to specify what further investigations are required.” He, like a lot of clinicians, is concerned about ill-informed consumers using these devices to make medical interventions without consulting a professional. 

Friston added that people shouldn’t expect wearable EEGs to be magic bullets for their brain health or cognition. He said the best way for a consumer to approach them is by treating them with the same level of reverence as a household thermometer. “Are thermometers useful in managing the wellness of my children?, Yes,” he explained, “can your thermometer tell you what particular virus you have? Absolutely not.” “In the context of well-being and to augment or validate practices such as mindfulness and meditation, they can be fun and useful quantitative devices.” But, fundamentally, that is all he feels they can be, especially right now.

Back in 2024, NASA announced that the Artemis 2 mission was going to be pushed back to April 2026. Now, the agency says it could launch as early as February, with the first flight opportunity being on February 6. NASA is currently making the final preparations for the mission and will soon roll out the Space Launch System (SLS) rocket and the Orion spacecraft to their launch pad at the Kennedy Space Center in Florida. The spacecraft system’s four-mile journey from the assembly building to Launch Pad 39B will take up to 12 hours. NASA is targeting a date no earlier than January 17, with the exact day depending on the weather and on the possible need for additional time to address technical issues.

Artemis 2 is the first crewed mission to the moon since the Apollo program’s final flight in 1972. The 10-day mission will have four astronauts on board who’ll be testing if Orion’s critical life support systems can sustain human passengers on future longer duration missions. They will first orbit the Earth twice before making their way 4,700 miles beyond the far side of the moon. If the SLS and Orion system is rolled out as planned, NASA intends to conduct a wet dress rehearsal at the end of January. The agency will load cryogenic propellants into the rocket and will do a full launch countdown during the rehearsal to prepare for the real event.

NASA has decided to bring the Crew-11 astronauts home a month earlier than originally planned due to a “medical concern” with one of them. This is the first time in its history that the space agency is cutting a mission short due to a medical issue, but it didn’t identify the crew member or divulge the exact situation and its severity. The agency is targeting a return date no earlier than January 14, with the exact schedule depending on the weather. If NASA’s original plan pushes through, the crew will splash down off the coast of California at approximately 3:40 AM on January 15.

The agency previously postponed an International Space Station (ISS) spacewalk scheduled for January 8, citing a medical concern with a crew member that appeared the day before. NASA’s chief health and medical officer, James “JD” Polk, said the affected astronaut is “absolutely stable” and that this isn’t a case of an emergency evacuation. The ISS has a “robust suite of medical hardware” onboard, he said, but not enough for a complete workup to determine a diagnosis. Without a proper diagnosis, NASA doesn’t know if the astronaut’s health could be negatively affected by the environment aboard the ISS. That is why the agency is erring on the side of caution.

Crew-11 left for the space station on August 1 and was supposed to come back to Earth on or around February 20. After they leave the station, only three people will remain: Two cosmonauts and one astronauts who’ll be in charge of all the experiments currently being conducted on the orbiting lab. The team’s replacement, Crew-12, was supposed to head to the ISS mid-February, but NASA is considering sending the astronauts to the station earlier than that.

Update, January 10, 2025, 5:15AM ET: This story has been updated to include Crew-11’s tentative return date.

While wave upon wave of smartglasses and face-based wearables crash on the shores of CES, traditional glasses really haven’t changed much over the hundreds of years we’ve been using them. The last innovation, arguably, was progressive multifocals that blended near and farsighted lenses — and that was back in the 1950s. It makes sense that autofocusing glasses maker IXI thinks it’s time to modernize glasses.

After recently announcing a 22-gram (0.7-ounce) prototype frame, the startup is here in Las Vegas to show off working prototypes of its lenses, a key component of its autofocus glasses, which could be a game-changer. 

IXI’s glasses are designed for age-related farsightedness, a condition that affects many, if not most people over 45. They combine cameraless eye tracking with liquid crystal lenses that automatically activate when the glasses detect the user’s focus shifting. This means that, instead of having two separate prescriptions, as in multifocal or bifocal lenses, IXI’s lenses automatically switch between each prescription. Crucially — like most modern smartglasses — the frames themselves are lightweight and look like just another pair of normal glasses.

Mat Smith for Engadget

With a row of prototype frames and lenses laid out in front of him, CEO and co-founder Niko Eiden explained the technology, which can be separated into two parts. First, the IXI glasses track the movement of your eyes using a system of LEDs and photodiodes, dotted around the edges of where the lenses sit. The LEDs bounce invisible infrared light off the eyes and then measure the reflection, detecting the subtle movements of your eye and how both eyes converge when focusing on something close.

Using infrared with just a "handful of analog channels" takes far less power than the millions of pixels and 60-times-per-second processing required by camera-based systems. IXI’s system not only tracks eye movements, but also blinking and gaze direction, while consuming only 4 milliwatts of power.

Mat Smith for Engadget

Most of the technology, including memory, sensors, driving electronics and eye tracker, is in the front frame of the glasses and part of the arms closest to the hinge. The IXI prototype apparently uses batteries similar in size to those found in AirPods, which gives some sense of the size and weight of the tech being used. The charging port is integrated into the glasses’ left arm hinge. Naturally, this does mean they can’t be worn while charging. IXI says that a single charge should cover a whole day’s usage.

The prototype frames I saw this week appeared to be roughly the same weight as my traditional chunky specs. And while these are early iterations, IXI’s first frames wouldn’t look out of place in a lineup of spectacle options.

The team has also refined the nose pieces and glasses arms to accommodate different face shapes. Apparently, when testing expanded from Finland to the UK, British faces were “...different.” A little harsh when talking to me, a Brit.

Eiden pulled out some prototype lenses, made up of layers of liquid crystal and a transparent ITO (indium tin oxide) conductive layer. This combination is still incredibly thin, and it was amazing to watch the layers switch almost instantly into a prescription lens. It seemed almost magical. As they’re so thin, they can be easily integrated into lenses with existing prescriptions. It can also provide cylindrical correction for astigmatism too.

Autofocus lenses could eliminate the need for multiple pairs of glasses, such as bifocals and progressives. Even if the glasses were to run out of power, they’d still function as a pair of traditional specs with your standard prescription, just lacking the near-sighted boost. IXI’s sensor sensitivity can also offer insight into other health conditions, detect dry eyes, estimate attentiveness and, by tracking where you’re looking, even posture and neck movement. According to Eiden, blink rate changes with focus, daydreaming and anxiety, and all that generates data that can be shown in the companion app.

Mat Smith for Engadget

Hypothetically, the product could even potentially adapt prescriptions dynamically, going beyond the simple vision correction of Gen 1. For example, it could offer stronger corrections as your eyes get fatigued through the day.

IXI appears to be putting the pieces in place to make these glasses a reality. It still needs to obtain the necessary medical certifications in order to sell its glasses and get all the production pieces in place. It’s already partnered with Swiss lens-maker Optiswiss for manufacturing. Eiden says the final product will be positioned as a high-end luxury glasses option, selling through existing opticians. The company hopes to finally launch its first pair sometime next year.

NASA has postponed an International Space Station (ISS) spacewalk that was scheduled for Thursday. "The agency is monitoring a medical concern with a crew member that arose Wednesday afternoon aboard the orbital complex," the agency wrote. On Thursday, NASA added that ending Crew-11's mission early was on the table.

The unnamed crew member is stable, according to NASA. Space News notes that Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) was heard on an open comms channel on Wednesday requesting a private medical conference with a flight surgeon. However, those requests are routine on the ISS, so we can’t assume the events were related.

"The matter involved a single crew member who is stable," NASA wrote. "Safely conducting our missions is our highest priority, and we are actively evaluating all options, including the possibility of an earlier end to Crew-11's mission."

Crew-11 was scheduled to remain on board the ISS until at least the second half of February. Its replacement, Crew-12, isn't slated to blast off until February 15 at the earliest.

NASA astronauts Mike Fincke and Zena Cardman had planned to exit the airlock on Thursday for the six-and-a-half-hour spacewalk. The short trip’s mission was to install a kit and cables in preparation for a new roll-out solar array that will arrive on a future mission.

The agency said it will provide further updates within 24 hours.
