Read more about how we evaluate products . Most people think of AirTags when they picture a Bluetooth tracker.

But now, both Google and Samsung have implemented finding networks o

Lightning on Earth is sparked by a powerful chain reaction from outer space

The energy needed for thunderstorms could come from an avalanche of electrons seeded by extraterrestrial cosmic rays , a new study claims. Scientists already knew that lightning is an electrical discharge between thunderclouds and Earth's surface, but exactly how storm clouds obtain an electric field powerful enough to hurl a bolt has remained a mystery for centuries. Now, a new study has used computer models to reveal that lightning strikes as the result of a powerful chain reaction that begi

These are the best streaming services you aren’t watching

We all know how to find our favorite shows and blockbuster films on mainstream streaming services like Netflix, HBO Max, and Disney+.

Meet Ultra Skelly: Skelly the Skeleton Gets a High-Tech Edition This Halloween

I know you've seen Skelly at some point in the past five years. Maybe it was driving around your neighborhood during Halloween, or on a viral post about Halloween decorations. Maybe both! Maybe it's in your friend's yard year-round, wearing a Santa hat for Christmas and rocking 2025 glasses with a bottle of champagne for the new year. (Maybe that's just my friend's yard.) The popular 12-foot skeleton, aptly named Skelly, has become a Halloween classic (and a permanent yard mainstay for the Hall

What’s Inside the Tiny Miracle Food Pouches That Can Save the Lives of Starving Gazans

Take a peanut-based paste packed with 500 calories and nearly 13 grams of protein. Store it in a 92-gram foil pouch, so it can be easily sucked by starving infants on the front line. No water or refrigeration is required, meaning it can be distributed in drought-hit areas and stored at ambient temperature for up to two years. Just a couple of daily sachets can lead to a 10 percent weight gain over six weeks, sustaining recovery from severe acute malnutrition for less than $60 per child. Saving a

The Subway Game (1980)

The Subway Game Copyright © 1980, Peter R. Samson (to home page) The Subway Game was a diversion that developed out of the frequent visits to New York by myself and various friends at M.I.T. In its basic form it requires two participants: an innocent victim, called the Contestant; and a more knowledgeable companion, called the Monitor. With some allowances, the game can be viewed as a simulation of the following scenario. A stranger to New York is going to visit some friends there. He gets a

Persona vectors: Monitoring and controlling character traits in language models

Language models are strange beasts. In many ways they appear to have human-like “personalities” and “moods,” but these traits are highly fluid and liable to change unexpectedly. Sometimes these changes are dramatic. In 2023, Microsoft's Bing chatbot famously adopted an alter-ego called "Sydney,” which declared love for users and made threats of blackmail. More recently, xAI’s Grok chatbot would for a brief period sometimes identify as “MechaHitler” and make antisemitic comments. Other personali

‘Cyberpunk: Edgerunners’ Star Lucy Finally Comes to ‘Guilty Gear Strive’

Fans of the Cyberpunk: Edgerunners anime have been looking forward to seeing Lucy cut it up in Guilty Gear Strive as a DLC character for a while now. During this weekend’s EVO tournament, Arc System Works finally pulled back the curtain on how everyone’s favorite living Edgerunner fits into its fighting game. Lucy’s appearance here looks to be justified through her mind being hacked and transferred to the Guilty Gear universe. Still dealing with the events of Edgerunners that left her old crew

Alarming New System Can Identify People Through Walls Using Wi-Fi Signal

Once upon a time, in their startling report titled "Bigger Monsters, Weaker Chains," ACLU analysts Jay Stanley and Barry Steinhardt argued that the US was quickly becoming a full-blown "surveillance society," where advanced technology and crumbling regulation come together to create the kind of world that was previously the domain of dystopian science fiction. "The fact is, there are no longer any technical barriers to the Big Brother regime portrayed by George Orwell," they wrote. That was in

Original Tesla Cofounder Roasts Cybertruck for Looking "Like a Dumpster"

Martin Eberhard, one of the original cofounders of Tesla — who actually started the company and didn't retroactively bestow himself a title giving that impression, unlike a certain billionaire — isn't too pleased with his baby's newest crowning jewel: the Cybertruck. In comments made in a recent interview with YouTuber Kim Java spotted by Electrek, Eberhard vented his frustration with Tesla's recent direction — which is when the highly heterodox pickup truck caught a stray. "I am actually disa

Too Hot Inside? These Houseplants Actually Help Beat the Heat

Looking for a smarter way to beat the summer heat without blasting your air conditioner all day? You might want to take a closer look at the houseplants sitting quietly on your windowsill. According to experts, certain indoor plants don't just brighten up a room, they can literally lower the temperature in your home. And yes, science backs it up.

Helsinki records zero traffic deaths for full year

“A lot of factors contributed to this, but speed limits are one of the most important,” said Roni Utriainen , traffic engineer with the city’s Urban Environment Division. Authorities described the milestone as exceptional and credited long-term planning, targeted infrastructure changes, and lower speed limits. Helsinki has completed an entire year without a single traffic-related fatality, according to city and police officials. The last recorded death occurred in early July 2024 in the Kontul

The SEC Shifts Gears on Crypto

The Securities and Exchange Commission made its biggest pro-crypto move yet this week. On Thursday, SEC Chairman Paul Atkins launched “Project Crypto,” an overarching roadmap of the Commission’s approach to regulating cryptocurrency. The aim of the project, according to Atkins, is to make the United States “the crypto capital of the world” by onshoring crypto asset distributions. Atkins hopes to do so by updating the Commission’s rules and regulations regarding on-chain software systems, encou

How to Clean Your Mattress (2025)

It’s important to know how to clean your mattress. Not just for day-to-day cleanliness and hygiene, but let’s say you’re dealing with an emergency—a “my mattress is ruined" situation where you have the frantic energy of an emergency clean-up crew. Is a trip to the dump inevitable? Not necessarily. Before you think, “I’m so clean, this would never happen to me!” I’m telling you, it can. I've seen a lot over the course of my career as a professional mattress tester and certified sleep coach. If y

C++26 Reflections adventures and compile-time UML

The first thing I do every time I need to learn a new codebase is to start drawing the UML diagram of its classes, and usually give up soon after I started. The process of doing it manually is certainly useful, but now with reflections I figure it would be fun to try generate it instead. With C++26 reflections[1] the general consensus is that the magnitude of language change is comparable to what happened with C++11. After my little experiment with it, I would cautiously agree. So how does one

We Must Admit That This Video of Two Small Robots Punching Each Other With Boxing Gloves Is Pretty Awesome

These days, robots with varying degrees of impressiveness can manage all kinds of tasks. But two diminutive humanoids seen boxing with outsize gloves at the recent World AI Conference in Shanghai may take the cake. In a video posted to X, AI security researcher Helen Toner — who was, it should be noted, a driving force behind the ultimately failed coup against CEO Sam Altman back in November 2023 — showed off the boxing ring prowess of two short-statured robots from the Chinese company Unitree.

A dive into open chat protocols

A dive into open chat protocols I’m between projects right now, so as is my idiom I’m going to take some random topic that has caught me on a manic swing in my little bipolar life, and dive deeper into it for a few days. One of the low-key topics in the back of my mind is that “the world needs an open chat protocol that doesn’t suck”, and something made me start thinking seriously about XMPP again for the first time in a decade. I used XMPP myself a fair amount in its little Golden Age of the e

I bought Samsung's Galaxy Watch Ultra 2025 - here's why I have buyer's remorse

Samsung Galaxy Watch Ultra ZDNET's key takeaways The Samsung Galaxy Watch Ultra is on sale for $650 in four color options.
