Powerful Webb Telescope captures photos of one of the earliest supernova ever seen

NASA’s James Webb Space Telescope (JWST) has captured photos of one of the earliest supernovas ever seen, with features appearing like grains and knots found in a cut of wood.

“Once upon a time, the core of a massive star collapsed, creating a shockwave that blasted outward, ripping the star apart as it went,” NASA said on its website. “When the shockwave reached the star’s surface, it punched through, generating a brief, intense pulse of X-rays and ultraviolet light that traveled outward into the surrounding space.”

Now, nearly 350 years later, scientists are getting a view of the aftermath as the pulse of light reaches interstellar material and causes it to glow.

The infrared glow created was captured by JWST, revealing details that look like knots and whorls found in wood grain.

This background image of the region around supernova remnant Cassiopeia A was released by NASA’s Spitzer Space Telescope in 2008. By taking multiple images of this region over three years with Spitzer, researchers were able to examine a number of light echoes. Now, NASA’s James Webb Space Telescope has imaged some of these light echoes in much greater detail.

“Even as a star dies, its light endures—echoing across the cosmos. It’s been an extraordinary three years since we launched NASA’s James Webb Space Telescope. Every image, every discovery, shows a portrait not only of the majesty of the universe but the power of the NASA team and the promise of international partnerships. This groundbreaking mission, NASA’s largest international space science collaboration, is a true testament to NASA’s ingenuity, teamwork, and pursuit of excellence,” NASA Administrator Bill Nelson said. “What a privilege it has been to oversee this monumental effort, shaped by the tireless dedication of thousands of scientists and engineers around the globe. This latest image beautifully captures the lasting legacy of Webb—a keyhole into the past and a mission that will inspire generations to come.”

While beautiful in nature, the observations also give astronomers the ability to map the 3-dimensional structure of the interstellar dust and gas for the first time.

“We were pretty shocked to see this level of detail,” Jacob Jencson of Caltech/IPAC in Pasadena, the principal investigator of the science program, said.

Josh Peek of the Space Telescope Science Institute in Baltimore is also a member of the team and said they see layers like those of an onion.

“We think every dense, dusty region that we see, and most of the ones we don’t see, look like this on the inside,” he said. “We just have never been able to look inside them before.”

The images produced from the JWST near-infrared camera (NIRCam) highlight a phenomenon called light echo, NASA said, which is created when a star explodes or erupts before flashing light into surrounding masses of dust and causing them to shine.

The visible light echoes are caused when the light reflects off interstellar material, where those at infrared wavelengths are caused when the dust is warmed by energetic radiation, causing it to glow.

Scientists targeted a light echo previously observed by NASA’s retired Spitzer Space Telescope, and it is one of dozens found near remains of the Cassiopeia A supernova.

The Webb images show tightly packed sheets, with filaments displaying structures on what NASA called “remarkably small scales,” of about 400 astronomical units, or less than one-hundredth of a light year. One astronomical unit is the average distance between the Earth and the Sun, and Neptune’s orbit is 60 astronomical units in diameter.

“We did not know that the interstellar medium had structures on that small of a scale, let alone that it was sheet-like,” Peek said.

The discovery was compared by scientists to a medical CT scan.

“We have three slices taken at three different times, which will allow us to study the true 3D structure. It will completely change the way we study the interstellar medium,” Armin Rest of the Space Telescope Science Institute, and member of the team, said.

The team’s findings will be presented this week at the 245th American Astronomical Society meeting in Washington, D.C.

The Webb Telescope, the successor to the Hubble and the largest telescope ever launched into space, is a joint project of NASA and the European Space Agency.

Samsung’s Digital Home Key lets you use your phone as your key

Just days after showing off the Galaxy S26, Samsung is finally rolling out the ability for users to unlock their home with a tap of their phone or by simply approaching their door. The new feature, called Digital Home Key, will live inside Samsung Wallet and is powered by the Aliro smart home standard.

Samsung first teased its Digital Home Key feature in 2024 and said the feature would be available in 2025. That didn’t pan out, as the CSA’s Aliro standard — which will let users unlock smart locks with any phone — only arrived in February of this year. The new standard uses near-field communication (NFC) for its tap-to-unlock technology. It also supports ultra-wideband (UWB), giving users the ability to unlock their door as they approach and without pulling out their phone.

To add a Digital Home Key to your wallet, you’ll need to set up a compatible smart lock through SmartThings using Matter. Only some Galaxy smartphones support both NFC and UWB, including the Galaxy Z Fold 4 and up, as well as the Galaxy S22 Ultra and up. You can view the full list of compatible devices on Samsung’s website.

China’s ultrasound brain tech race heats up

NEWYou can now listen to Fox News articles!

When you hear “brain-computer interface,” you probably picture surgery, wires and a chip in your head. Now picture something quieter. No implant. No incision. Just sound waves directed at the brain.

That is the approach behind a new wave of ultrasound brain-computer interface companies in China. One of the newest is Gestala, founded in Chengdu with offices in Shanghai and Hong Kong. The company says it is developing technology that can stimulate and eventually study brain activity using focused ultrasound.

Yes, the same basic technology is used in medical imaging. But this time, it targets neural circuits.

What is an ultrasound brain computer interface?

Most brain-computer interface systems rely on electrodes that detect electrical signals from neurons. Neuralink is the most visible example. It places tiny threads inside the brain to record activity. Ultrasound works differently.

Instead of measuring electrical signals directly, it uses high-frequency sound waves. Depending on intensity and focus, those waves can:

Create images of internal tissue
Destroy abnormal tissue such as tumors
Modulate neural activity without open surgery.

Focused ultrasound treatments are already approved for Parkinson’s disease, uterine fibroids and certain tumors. That clinical history gives companies like Gestala a foundation to build on. However, studying or interpreting brain signals with ultrasound is far more complex than delivering targeted stimulation.

How Gestala plans to treat chronic pain with focused ultrasound

Gestala’s first product is focused on chronic pain. The company plans to target the anterior cingulate cortex, a brain region linked to the emotional experience of pain. Early pilot studies suggest that stimulating this area can reduce pain intensity for up to a week in some patients. The first-generation device will be a stationary system used in clinics. Patients would visit a hospital for treatment sessions. Later, the company plans to develop a wearable helmet designed for supervised use at home. Over time, Gestala says it wants to expand into depression, other mental health conditions, stroke rehabilitation, Alzheimer’s disease and sleep disorders. That is an ambitious roadmap. Each condition involves different brain networks and clinical hurdles.

Can ultrasound read brain activity without implants?

Like other brain tech startups, Gestala is also exploring whether ultrasound could help interpret brain activity. The long-term concept is straightforward in theory. A device could detect patterns linked to chronic pain or depression, then deliver stimulation to specific regions in response.

Unlike traditional brain implants, which capture electrical signals from limited areas, an ultrasound-based system may have the potential to access broader regions of the brain. That possibility is one reason researchers are paying attention. Still, translating that concept into reliable data is a major engineering challenge.

The global race to build noninvasive brain interfaces

China is not alone in exploring ultrasound brain-computer interface systems. Earlier this month, OpenAI announced a significant investment in Merge Labs, a startup cofounded by Sam Altman along with researchers linked to Forest Neurotech.

Public materials from Merge Labs mention restoring lost abilities, supporting healthier brain states and deepening human connection with advanced AI. That language signals long-term ambitions. Yet experts caution that real-world applications are still years away.

The technical limits of ultrasound brain interfaces

Ultrasound faces technical limits. First, the skull weakens and distorts sound waves. That makes it harder to obtain precise signals. In research settings, detailed readouts of neural activity have required special implants that allow ultrasound to pass more clearly than bone.

Second, ultrasound measures changes in blood flow. Blood flow shifts more slowly than electrical firing in neurons. That delay may limit applications that require fast, detailed signal decoding, such as real-time speech translation. In short, stimulation is one challenge. Accurate readout is another level entirely.

What this means to you

Right now, this technology is experimental. You are not about to buy a brain helmet at your local electronics store. Still, the direction matters. If noninvasive ultrasound devices can reduce chronic pain or support mental health treatment, more patients may consider therapy without facing brain surgery.

At the same time, devices that analyze brain states introduce new privacy questions. Brain-related data is deeply personal. Regulators, hospitals and companies will need clear rules about how that data is stored, shared and protected. Finally, the link between AI companies and brain interface startups shows how closely digital intelligence and neuroscience are becoming intertwined. That connection could reshape medicine, wellness, and even how we interact with technology.

Kurt’s key takeaways

Brain-computer interfaces used to feel far off and experimental. Now they are a serious focus of global research and investment. China’s push to develop an ultrasound-based brain-computer interface adds momentum to a field already shaped by companies like Neuralink and new ventures backed by OpenAI. Progress is steady but measured. The potential is significant. The technical hurdles are real. What happens next will depend on whether researchers can turn promising lab results into safe, reliable treatments people can actually use.

If sound waves could one day interpret your mental state, who should decide how that information is used? Let us know by writing to us at Cyberguy.com.

This Windows gaming handheld has a screen that folds in half

Lenovo put a foldable display on a gaming handheld. The Legion Go Fold Concept is a Windows-based handheld with a flexible POLED display, detachable Joy-Con-like controllers, and a folio case to turn the whole thing into a mini laptop.

You can use it as a standard Steam Deck-esque handheld with the display folded down to 7.7 inches and controllers attached at its sides, or you can unfold it for a bigger experience. When unfolded, the controllers can be repositioned to all four sides, allowing you to play with the screen in vertical or horizontal orientations.

In vertical splitscreen mode, you can put your game on one half of the screen and a second window (like your chat or game guide) on the other half. Horizontal fullscreen mode gives your game the full 11.6 inches of real estate in a 16:10 aspect ratio. To go into laptop mode, you remove the controllers and mount the handheld into a folio case with a stand, built-in keyboard, and trackpad. The controllers can be put into a separate grip mount to unify them as one gamepad.

There are a lot of ways you can use this folding handheld, including turning one of its controllers into a vertical mouse like on other Legion Go handhelds, but there’s one thing it doesn’t do: fold down to close and protect its screen. The Go Fold only folds outwards, so don’t expect a Nintendo DS or GameBoy Advance-like clamshell that closes for portability. Instead, it’s all about getting bigger than your average gaming handheld and offering more. (Though we’ve tried bigger before.)

The Legion Go Fold has some formidable specs: an Intel Core Ultra 7 258V Lunar Lake processor, 32GB of RAM, 1TB of storage, and a 48Whr battery. The plastic-covered OLED has a resolution of 2435 x 1712 and 165Hz refresh rate. And there’s even a second, circular toushscreen on the right controller, under the face buttons. It doubles as a touchpad and can be a support display, allowing you to swipe between extracted UI elements from a game (which I wouldn’t expect to be widely supported), a clock, system monitoring, or an animated GIF (just for fun).

During my brief in-person demo I didn’t get to play any graphically-intense games — just Balatro, which can practically play on a potato. The screen looked plenty sharp, but like any foldable there’s a crease down the middle; it’s very visible, but you learn to look past it and ignore it after just a bit. The build and feel of the whole thing felt a little fragile, and detaching and reattaching the controllers was definitely janky. Build quality will hopefully be improved if this device ever actually makes it to market.

The laptop mode was a pleasant surprise for me though. I did not expect a gaming handheld to double as a conventional computer you could get work done on. The Legion Go Fold’s case took quite a bit of fumbling before I set it up correctly, but it shouldn’t take too long to get used to if you actually lived with it.

Then again, I don’t know if anyone is going to be able to live with this thing — ever. I’d love for the Legion Go Fold to go from concept to real product like other out-there Lenovo ideas, but I shudder to think what it might cost. The Legion Go 2 is already priced well over $1,000. And with the ongoing RAMageddon crisis we’re living through, there’s no telling how much more expensive an actual Legion Go Fold would be if it came out in a year or more.

But even if it’s not the kind of foldable I expected, and even though it may never come out, it’s certainly cool. Now somebody please make a folding PC handheld that goes from kinda-big to really small. I think that’d be the one for me.
