Scientists have traced the galactic origins of thousands of “ghost particles” known as neutrinos to create the first-ever portrait of the Milky Way made from matter and not light — and it’s given them a brand-new way to study the universe.
The groundbreaking image was snapped by capturing the neutrinos as they fell through the IceCube Neutrino Observatory, a gigantic detector buried deep inside the South Pole’s ice.
Neutrinos earn their spooky nickname because their nonexistent electrical charge and almost-zero mass mean they barely interact with other types of matter. As such, neutrinos fly straight through regular matter at close to the speed of light.

Yet by slowing these neutrinos, physicists have finally traced the particles’ origins billions of light-years away to ancient, cataclysmic stellar explosions and cosmic-ray collisions. The researchers published their findings June 29 in the journal Science.
“The capabilities provided by the highly sensitive IceCube detector, coupled with new data analysis tools, have given us an entirely new view of our galaxy — one that had only been hinted at before,” Denise Caldwell, director of the National Science Foundation’s physics division, which funded the research, said in a statement. “As these capabilities continue to be refined, we can look forward to watching this picture emerge with ever-increasing resolution, potentially revealing hidden features of our galaxy never before seen by humanity.”

Every second, about 100 billion neutrinos pass through each square centimeter of your body. The tiny particles are everywhere — produced in the nuclear fire of stars, in enormous supernova explosions, by cosmic rays and radioactive decay, and in particle accelerators and nuclear reactors on Earth. In fact, neutrinos, which were first discovered zipping out of a nuclear reactor in 1956, are second only to photons as the most abundant subatomic particles in the universe.
Despite their ubiquity, the chargeless and near-massless particles’ minimal interactions with other matter make neutrinos incredibly difficult to detect. Many famous neutrino-detection experiments have spotted the steady bombardment of neutrinos sent to us from the sun, but this cascade also masks neutrinos from more unusual sources, such as gigantic star explosions called supernovas and particle showers produced by cosmic rays.
To capture the neutrinos, particle physicists turned to IceCube, located at the Amundsen-Scott South Pole Station in Antarctica. The gigantic detector consists of more than 5,000 optical sensors beaded across 86 strings that dangle into holes drilled up to 1.56 miles (2.5 kilometers) into the Antarctic ice.

While many neutrinos pass completely unimpeded through the Earth, they do occasionally interact with water molecules, creating particle byproducts called muons that can be witnessed as flashes of light inside the detector’s sensors. From the patterns these flashes make, scientists can reconstruct the energy, and sometimes the sources, of the neutrinos.
Finding a neutrino’s starting point depends on how clear its direction is recorded in the detector; some have very obvious initial directions, whereas others produce cascading “fuzz balls of light” that obscure their origins, lead author Naoko Kurahashi Neilson, a physicist at Drexel University in Philadelphia, said in the statement.RELATED STORIES—Astronomers propose making a neutrino detector out of the Pacific Ocean

By feeding more than 60,000 detected neutrino cascades collected over 10 years into a machine-learning algorithm, the physicists built up a stunning picture: an ethereal, blue-tinged image showing the neutrinos’ sources all across our galaxy.
The map showed that the neutrinos were being overwhelmingly produced in regions with previously detected high gamma-ray counts, confirming past suspicions that many ghost particles are summoned as byproducts of cosmic rays smashing into interstellar gas. It also left the physicists awestruck.
“I remember saying, ‘At this point in human history, we’re the first ones to see our galaxy in anything other than light,'” Neilson said.
Just like previous revolutionary advances such as radio astronomy, infrared astronomy and gravitational wave detection, neutrino mapping has given us a completely new way to peer out into the universe. Now, it’s time to see what we find.
A woman has been charged with fraud offences over the alleged sale of Oasis tickets.
Rosie Slater has been charged with 11 counts of fraud by false representation, Staffordshire Police said.
The 32-year-old, of Newcastle-under-Lyme, Staffordshire, has been granted unconditional bail and is due to appear in court at North Staffordshire Justice Centre on 11 December.
The charges relate to the alleged sale of Oasis tickets in May.
It comes as ministers confirmed plans to make it illegal for tickets to concerts, theatre, comedy, sport and other live events to be resold for more than their original cost.
Earlier this month, pop stars including Sam Fender, Dua Lipa, Coldplay and Radiohead urged the prime minister in an open letter to stand by his election promise to restrict online ticket touts.
The huge profits made by resellers were put in the spotlight last year when thousands of Oasis fans complained of ticket prices for their reunion tour, with some Wembley Stadium show tickets listed at more than £4,000.
Three years since the arrival of OpenAI‘s ChatGPT, more devices featuring generative AI technology have hit the market in time for the 2025 holiday shopping season, with many offering deals for Black Friday.
Shoppers can pick from more advanced smart glasses, smart speakers with genAI and a pendant AI friend that acts as a confidant.
These latest gizmos come from megacaps like Amazon, Alphabet and Meta and smaller players like Friend and Plaud.
Despite the arrival of this new wave of products, reviews for many of the devices are mixed, and nothing has separated itself as a clear leader of the pack.
That’s in part because much of the spending on artificial intelligence has been focused on other things.
Since ChatGPT was released in late 2022, the bulk of the tech industry has reoriented itself to prioritize building out large language models in a race to reach artificial general intelligence, or AI with the capabilities that are on par with, or surpass, humans.
Thus far, much of the development in Silicon Valley has focused on AI apps, including chatbots like Anthropic’sClaude, image generators like Google’s Nano Banana or feeds for AI-generated short-form videos like OpenAI’s Sora. All things people can access on their existing smartphones without a spiffy new gadget.
But the world of AI hardware is growing fast.
If you’re in the market for the latest AI devices, here’s what’s available to snag this holiday season.

Alexa+ Echo speakers
Amazon wants to make sure its Alexa voice assistant and Echo smart speakers don’t get left behind in the era of genAI.
The company unveiled Alexa+ in February, promising a smarter, more conversational and personalized version of its 11-year-old digital assistant. In September, it followed up with a new set of Echo speakers and displays, which are the first devices to come with Alexa+ out of the box.
The lineup includes a $100 Echo Dot Max, $180 Echo Show, $220 Echo Studio and $220 Echo Show 11.
The Echo Dot Max is an entry-level, all-purpose smart speaker, while the Echo Studio is larger, pricier and offers better sound quality. The main difference between Amazon’s smart displays, the Echo Show 8 and Echo Show 11, is the touchscreen size.
All of the devices have improved sensors, speakers and microphones.
Amazon is offering 11% off the cost of the Echo Show 11 and 10% off the Echo Dot Max as part of its Black Friday promotions.
With the upgrades, Amazon is aiming to have users engage more often with the devices than their predecessors. Consumers frequently complained that Alexa had grown outdated while the Echo devices offered little utility beyond setting timers, spouting weather forecasts, playing music and controlling smart home accessories, like turning lights on and off.
Amazon’s recent Alexa ad tries to paint a different picture.
Comedian Pete Davidson strolls through his kitchen when an Alexa-equipped Echo Show announces, unprompted, that the “Coffee’s on, and your Uber is on its way.” Davidson then casually banters back and forth with Alexa about his preferred nickname.
The interaction is meant to showcase a few of Alexa+’s biggest selling points — users don’t have to repeat a so-called “wake word” after every command, allowing the conversation to flow more naturally.
The devices can also now connect to external services to take actions on users’ behalf. As of now, Alexa+ can book an Uber or OpenTable reservation, generate a song via Suno, plan a trip through Fodor’s, schedule a repairman visit and purchase concert tickets through Ticketmaster. Amazon has said it expects to add more capabilities soon.
Alexa+ isn’t yet available to the general public. Consumers have to wait to receive Early Access or purchase a new Echo model to use it.
Amazon is offering Alexa+ for free to users with Early Access, but at some point, the company will begin charging non-Prime members $19.99 a month for the service.
The company is also making moves in wearables.
Amazon in July announced plans to acquire AI company Bee for an undisclosed amount, indicating that it could have more hardware infused with the technology in the works. Bee is known for its $50 wristband that uses AI and microphones to listen to and analyze conversations, then provide to-do lists, summaries and reminders for everyday tasks.

Google’s AI-powered Pixel 10 series
Although the Gemini-powered Google Home Speaker won’t roll out until the spring, Alphabet did deliver some generative AI tech this year.
Launched in August, the Pixel 10 smartphones thoroughly integrate Google’s AI into several features, such as live translation, text-based photo editing and the built-in Gemini assistant.
The baseline Pixel 10 starts at $799, while the Pro lineup includes the $999 Pixel 10 Pro, the $1,199 Pixel Pro XL and the $1,799 Pixel 10 Pro Fold. The Pro line offers a higher quality camera and display, as well as additional video features.
Among the AI products is “Magic Cue,” which connects data across different apps to surface relevant information and suggest helpful actions. For example, if a user receives a message asking about a dinner reservation’s location, Magic Cue can find the answer from the calendar app.
For snapping pictures, Google provides an AI “Camera Coach,” which scans the scene of a photo and offers recommendations about framing, lighting and other techniques to improve the image.
The Pixel 10 Pro phones come with a one-year subscription to Google’s “AI Pro” plan, which typically costs $19 per month and offers multiple AI tools, including writing assistant NotebookLM and video generator Veo 3.
All the Pixel 10 models are currently on sale for $200 to $300 off until Dec. 6, except for the Pixel 10 Pro Fold, which has a $300 markdown until Dec. 2, the company said.

Meta’s AI-infused Ray-Ban smart glasses
Meta’s partnership with eyewear giant EssilorLuxottica, originally inked in 2019, has spawned a surprise hit in the Ray-Ban Meta smart glasses that both companies are keen to boast about.
With the Meta AI digital assistant, users can command the camera-equipped glasses to take photos, play tunes and to answer questions about nearby landmarks.
In September, the two companies debuted the latest version of the glasses, dubbed Ray-Ban Meta (Gen 2).
The new model has double the battery life of its predecessor and an improved camera. It costs $379, which is $80 than the prior version.
Meta and Luxottica this year also launched two smart glasses aimed at athletes under the Oakley brand.
The $399 Oakley Meta HSTN glasses are pitched toward casual athletes who want to take photos while playing sports like golf, while the $499 Oakley Meta Vanguard smart glasses are geared toward the action-sports crowd, like skiers.
The Vanguard glasses feature a flashier wraparound design and two buttons on the frames’ underside that lets helmet-wearing athletes easily take photos and videos and perform other actions.
For those willing to spend big money and test new technology, Meta and Luxottica also rolled out the $799 Meta Ray-Ban Display glasses in September.
They are the first glasses Meta sells to the public that include a display, albeit a small one, in just one of the lenses. The display is intended to show users small bits of information, like navigation directions. The glasses also include a wristband that utilizes neural technology so users can command the device with gestures like rotating one’s fingers to adjust volume.
Buying the $799 glasses, though, is not easy.
Meta requires that people sign-up for in-person demos at stores like Best Buy and LensCrafters before buying the product, and the company warns that “availability varies by store, so you may not be able to purchase a pair immediately after your demo.”
Early reviews for the display glasses have been mixed.
Some reviewers have praised the device’s color display, camera and innovative wristband. Still, others have criticized its high price and have said its lack of apps limit functionality.
Meta is currently offering a few Black Friday and Cyber Monday deals for some of its various AI-powered smart glasses that will last until Dec. 1.
People can save 20% on all versions of the Ray-Ban Meta (Gen 1) at Best Buy, Target, Amazon and also at Meta’s website and the Ray-Ban website and stores. Meta is also offering 20% off the cost of prescription lenses for people who buy the Ray-Ban Meta (Gen 2) and Oakley Meta HSTN glasses from its website.

The AI friend you wear around as a pendant
Most AI chatbots want to make the user more productive. The makers of this smart pendant want AI to be your friend.
Users wear Friend, as the product is aptly called, around their necks while the $129 device listens to the conversations happening around it.
Friend’s chatbot is powered by Google Gemini, and it offers commentary on the user’s conversation and life. Those comments appear as notifications through the device’s corresponding smartphone app.
For example, when one reviewer played a new Taylor Swift song for her AI friend, the device commented through a notification that it didn’t “think it’s bad at all” and “pretty typical for pop.”
The device is at the center of the societal debate about the rise of AI.
Friend plastered a subway station in New York this fall with ads that suggested that the pendant was better than a real friend, promising that it “will never bail on our dinner plans.”
The posters were immediately defaced with messages like “AI wouldn’t care if you lived or died.”
Those wanting to experience what it’s like to wear around an AI friend should place orders swiftly.
The company’s website currently says units will be shipping “Winter 2025/26,” but Friend founder Avi Schiffmann told CNBC that devices ordered early enough will ship before Christmas.

Plaud, the AI recorder
The Plaud Note looks more like a credit card than a voice recorder, but it’s an ideal purchase for any note taker who wants to capture meetings, lectures or any dictation.
With over 30 hours of recording time and battery that last 60 days on standby, the slim device can produce transcriptions in 112 languages. The transcriptions include tags for each speaker on the audio.
The recorder’s companion app is powered by OpenAI’s GPT-5, Anthropic’s Claude Sonnet 4 and Google’s Gemini 2.5 Pro. The app uses those AI models to generate detailed summaries and notes. Users can select from over 3,000 summary templates, such as phone Q&As or seminar notes.
The Plaud App’s basic plan offers 300 minutes of transcription per month, though users can upgrade to a pro plan for 1,200 minutes for $8.33 per month or a more expensive unlimited plan for $19.99 per month.
The recorder can easily be attached to phones with MagSafe magnets, meaning all Apple smartphones since the iPhone 12 series, or phone cases with similar magnets.
The company also offers the Plaud NotePin, a smaller, pill-shaped version of the recorder that can be worn as a magnetic pin, clip, wristband or necklace.
Typically priced at $159, both devices are currently on sale for 20% off during Black Friday and Cyber Monday, with another 15% markdown set for Christmas, the company said.
Scientists at Georgia Tech have created an AI technique that pre-trains exoskeleton controllers using existing human motion datasets, removing the need for lengthy lab-based retraining. The system predicts joint behavior and assistance needs, enabling controllers that work as well as hand-tuned versions. This advance accelerates prototype development and could improve…
