Astronomers 3D-print stellar nurseries you can hold in your hand
There’s a beautiful new way to visualize the places where stars come from.
Nia Amara is both an astrophysicist and an artist. Those two passions have united in a project that’s helping scientists visualize stellar nurseries, the massive clouds of dust and gas where stars are born.
Amara and her team 3D-printed polished, baseball-size orbs that look like oversized marbles with swirling patterns inside. «We wanted an interactive object to help us visualize those structures where stars form so we can better understand the physical processes,» said Imara in a University of California, Santa Cruz, statement Thursday.
The models are made from opaque resin deposited inside transparent resin, which makes it look like the cosmic clouds are suspended within each globe. The researchers also made half-spheres that give a view into the cross sections of the nurseries.
The patterns came from running simulations of star-forming clouds that show how different processes affect stellar nurseries. Subtle differences in the simulation results stand out when seen in 3D.
«Just aesthetically they are really amazing to look at, and then you begin to notice the complex structures that are incredibly difficult to see with the usual techniques for visualizing these simulations,» said the Flatiron Institute’s John Forbes, co-author of a paper on the project published in The Astrophysical Journal Letters in August.
We’re used to viewing cosmic wonders like galaxies and nebulae on screens. Now imagine those celestial sights being rendered in a way that lets you hold them up, turn them and see into them. That’s a marvelous possibility suggested by Amara’s clever blend of astronomy and art.

20 technologies that appeared in Verum Messenger earlier than in most messaging apps
The messaging market has long been dominated by a few major platforms. However, technological innovations often emerge not from the largest companies, but from new projects that implement ideas faster.
One such project is Verum Messenger — a platform that introduced a number of features long before they began appearing in other popular messaging apps.
Below are the key technologies of Verum Messenger, many of which were introduced years before similar features appeared in other services:
1 Artificial Intelligence inside the messenger
Users can interact with an AI assistant directly within chats.
2 Message scheduling
A message can be written in advance and sent at a specific time.
3 Self-destructing messages
Messages can automatically delete after a specified period of time.
4 Editing sent messages

Can You Tell if You’re Being Filmed by Smart Glasses? Here’s What the Devices Look Like
You don’t want to be secretly recorded by a wearer of Meta Ray-Bans. We’ll explain the distinguishing features of popular smart glasses.
Meta is facing another lawsuit, after an investigation by Swedish news outlets found that photos and videos captured by the company’s smart glasses can be reviewed by overseas workers. The lawsuit alleges that this access to footage — including sensitive content like nudity — goes against privacy laws and Meta’s own advertising claims.
Let’s backtrack: Meta Ray-Bans look like a chunkier pair of normal black Ray-Ban Wayfarers, and the average person probably wouldn’t suspect that those frames contain a hidden camera.
When I told my friend about them, she was disgusted. «Ew,» she said. «Why do those exist?»
I’ve never owned a pair of smart glasses, but I saw them in the wild twice last year. Once was when I was riding the New York City subway and noticed a person sitting across from me wearing the frames.
The other time was when I struck up a conversation with a guy at a bar. It took a minute in the dimly lit room, but then I recognized the telltale signs of his smart glasses.
I was unsettled. For a moment, I had the feeling of encountering an urban creature like a rat or raccoon, and I didn’t know how to behave.
«Act natural,» I told myself. He wasn’t recording me (I’m pretty certain), but I knew that he could be.
Smart glasses and privacy problems
Much of the general public still doesn’t know anything about smart glasses, and that’s a major problem.
Some smart glasses wearers are exploiting the ignorance by harassing strangers and filming their reactions. Many of their victims are homeless people, service workers and women.
These glasses aren’t a niche product, either. Meta sold 7 million pairs of smart glasses in 2025. For a relatively low price (they start at $300), «manfluencers» and other content creators can buy a pair of Meta Ray-Bans and use them to record unwitting subjects.
Smart glasses can be used to surveil people who participate in protests or secretly record people in restrooms and other public places. The privacy problem will only get worse if companies add facial recognition features to their smart glasses — and Meta is reportedly planning to do just that.
It may not always be possible to stop someone from filming you in public without your consent. But you can make it harder for this new generation of «glassholes» to film you in secret. The first step is knowing how to identify the technology.
What do smart glasses look like?
Not all smart glasses look alike, and not all models have cameras. The vast majority of camera glasses currently available are produced by Meta.
The easiest way to identify a pair is by locating the indicator light — a small LED bulb that turns on when the wearer is taking a picture or video.
According to CNET editor and wearable tech expert Scott Stein, «Each pair of smart glasses has its own type of indicator. And many smart glasses do different things. We don’t have a clear mental map of what to look for. That’s a big part of the problem.»
Meta Ray-Bans have been around since 2021. (They launched under the name Ray-Ban Stories.) A slimmer second-generation model was introduced in 2023.
The latest iteration includes a small screen built into one of the lenses, though from most angles, this feature is only visible to the wearer.
All Meta Ray-Ban models have relatively thick plastic frames with a camera lens located in the frame’s upper left corner (or upper right if you’re facing the wearer). On the opposite corner is the LED light, which automatically turns on when the wearer is filming. It lights up when a photo is taken and pulses when recording a video.
To take a photo or record a video, the user presses the capture button on the right arm of the glasses (near the LED light). The user can also use voice commands: «Hey Meta, take a photo» or «Hey Meta, take a video.»
Meta also produces glasses in partnership with Oakley. The HSTN model looks like a rounded version of the Ray-Ban frames, with the camera and LED in the same location. But the Vanguard model looks more like wraparound goggles than glasses, and its camera and LED are found in the center of the nose bridge.
In addition to the indicator LED is an audio cue: A shutter snap sound can be heard when a picture is taken. However, both of these cues are relatively subtle.
Even if you’re aware of smart glasses indicators, you might not know for sure if you’re being filmed. Outside in direct sunlight, it’s virtually impossible to detect when the recording light is on.
Smart glasses owners can also cover up the LED with a sticker or modify the frame to disable the light altogether (though they aren’t supposed to do this). And Amazon sells some pairs of glasses with a pinhole camera, which seem tailor-made for creeps to record people in secret.
The smart glasses future is already here
Smart glasses are a relatively new technology with plenty of potential. They can be useful for visually impaired people. They allow artists, woodworkers, chefs and other creators to capture footage while their hands are occupied.
But they can also be dangerous.
Unfortunately, few current laws regulate smart glasses and deter abusers. But as the devices become more common, social norms will develop and guide their usage, just as social norms developed for recording with phones.
By being able to recognize smart glasses in public, you’re reducing the chances for pranksters and bad actors to exploit you. You’re helping to shape this emergent technology, to define what it can — and can’t — do.

Google’s Canvas AI Project-Planning Tool Is Now Available to Everyone in the US
The AI workspace offers a dedicated space to organize plans and projects.
Canvas, the AI planning tool from Google Search, has rolled out across the US, the company said Wednesday. Canvas is essentially a project planning tool with a range of uses, including trip planning. You can select the tool directly from the AI Mode screen at the top of the Google Search results page.
The tool is integrated into AI Mode and can be used on both desktop and mobile devices, including smartphones and tablets. However, because Canvas opens a second screen beside the main chat window, it’s a little trickier to see on a smartphone. You’ll have to toggle between the screens.
Going anywhere? Maybe college?
Planning trips is one of Canvas’s main functions, with the ability to view and account for flights, hotels and other relevant information in real time.
«Canvas makes it easy to build travel plans customized for your specific needs — bringing together real-time Search data for flights and hotels, details from Google Maps like photos and reviews, and relevant information from sites across the web,» a Google spokesperson told CNET.
Google also notes you can use Canvas as an academic scholarship tracker, which includes dollar amounts and deadlines.
Project planning with AI
Once you’re in the AI Mode screen on Google, you can select the Canvas option from the plus sign that appears on the left side of the box where you type.
Clicking the Canvas button opens the project in a side panel. From there, you can refine the project with the standard chat prompts. You can even look at the underlying code and adjust the Canvas window’s user interface, such as switching to dark mode.
Rose Yao, vice president of product for Google Search, posted a thread on X on Wednesday, sharing a video of a summer camp project for her kids. Canvas created an interactive dashboard that sorts camp options by cost, distance and focus.
«We’re adding support for coding & creative writing tasks, so you can bring even more ideas to life with custom dashboards or interactive tools,» Yao wrote in the post.
Google first announced Canvas for AI Mode in July 2025, and later that year, expanded Canvas’s travel features.
There’s no word yet from Google on when Canvas will expand into other languages and other countries.
