The Weight of a Cell

Ella Watkins-Dulaney Microbes are so small that tens of thousands could fit in the space of the period at the end of this sentence. And yet, for two of the most widely studied kinds — S. cerevisiae and E. coli — we know their weight with remarkable precision: A single yeast cell weighs about 100 picograms and a single E. coli bacterium weighs about one picogram, or 60 million times less than a grain of sand. At first blush, measuring the weight of a single cell seems an impossible task. How ca

Valiant’s Bloodshot Relaunch Mired by Transphobic Dogwhistles

Update, 8/17/2025 @ 10:57 AM: After his old Twitter posts were discovered, Bloodshot writer Mauro Mantella has since deleted the account and posted an apology on Instagram. “I want to offer my most sincere apologies. I know I made a mistake, but at no point did I intend to spread a message of hate,” it begins. In his apology, he revealed he first wrote the issue’s script in Spanish, then “changed it a bit” when converting it to English. This conversion led to him “borrowing a common phrase used

The Mandarin Strikes In Hasbro’s Newest Marvel Legends Reveal

The Mandarin is one of Iron Man’s oldest foes, with a history in the comics as long as it is fraught. But while the character has been adapted multiple times over the course of the MCU—first more controversially with Ben Kingsley’s Trevor Slattery character in Iron Man 3, then as Tony Leung’s Xu Wenwu in Shang-Chi and the Legend of the Ten Rings—and earned himself a few action figures from Hasbro inspired by those appearances along the way, the toymaker has yet to bring a comics version of the v

Scientists Confirm What Every Beachgoer Secretly Fears About Seabirds

As a seabird researcher, Leo Uesaka spends most of his time reviewing hours of bird footage. That can get quite tedious and demanding at times, but every second is worth paying attention to—after all, that’s how you notice things like the penchant for seabirds to poop only while airborne. In a first-of-its-kind study published today in Current Biology, Uesaka and his team report that streaked shearwaters—large, unassuming seabirds common in East Asian waters—engage in a very specific type of ba

This $320 Kit Brings the BlackBerry Classic Back From the Dead

People are bored of their phones. So bored of their big, boring glass and metal slabs that they can’t help but dump all over phones like Nothing’s Phone 3 that don’t look like boring-ass bricks. But apparently people are so bored of their phones that somebody went and made a whole-ass kit that replaces the guts of the long-dead BlackBerry Q20, or “Classic,” with new components and effectively modernizes it with Android. Beloved for its QWERTY keyboard and BlackBerry OS (who remembers BBM?), the

These Chunks of Ice Move All By Themselves, Thanks to a Cool Engineering Trick

It looks like something straight out of a Ouija board horror movie, but frosty—researchers have figured out how to make ice move by itself. A video capturing the creepy dynamic features an ice disk melting on a metal surface etched with an asymmetrical herringbone pattern. The ice and its small puddle slowly start to move sideways before suddenly picking up speed and slingshotting across the metal plate. The researchers suggest that this sort of independent movement could one day generate power

The Biggest Winners of China’s World Humanoid Robot Games

China just hosted the first-ever World Humanoid Robot Games—basically the Olympics, but for robots. The three-day event kicked off Thursday, August 14, inside Beijing’s 12,000-seat National Speed Skating Oval, a venue originally built for the 2022 Winter Olympics. Over 200 teams from 16 countries including Japan, Brazil, Germany, and the U.S., competed across 26 competitions. The contests ranged from classic track-and-field events and gymnastics to kickboxing, soccer, medicine sorting, and even

Picking a Spot for NASA’s Lunar Nuclear Reactor Is Trickier Than It Sounds

In a bold, strategic move for the U.S., acting NASA Administrator Sean Duffy announced plans on Aug. 5, 2025, to build a nuclear fission reactor for deployment on the lunar surface in 2030. Doing so would allow the United States to gain a foothold on the Moon by the time China plans to land the first taikonaut, what China calls its astronauts, there by 2030. Apart from the geopolitical importance, there are other reasons why this move is critically important. A source of nuclear energy will be

This Newly Launched Satellite Just ‘Bloomed’ a Record-Breaking Antenna in Orbit

A first-of-its-kind satellite recently launched into orbit to monitor Earth’s changing surfaces, detecting movement of the planet’s crust down to fractions of an inch. The satellite packed a giant radar antenna, folded like an umbrella, and it just unfurled the massive, drum-shaped structure through an intricate process that brought it to full bloom. The NISAR mission, a joint effort between NASA and the Indian space agency ISRO, launched on July 30 from Satish Dhawan Space Centre in India. Mor

How the head of Obsidian went from superfan to CEO

Welcome to Decoder! This is Casey Newton, founder and editor of Platformer and cohost of the Hard Fork podcast. I’ve had a lot of fun guest-hosting a few episodes of Decoder while Nilay is out on parental leave this summer. If you listened to the last couple of Monday shows, you know I’ve been doing a series with founders who are focused on productivity. This is my third and, sadly, last time joining the show during the break, but I’m very excited about this episode. Today I’m talking with Step

Why Paradigm built a spreadsheet with an AI agent in every cell

Anna Monaco has been building AI agents since before the term “AI agents” was even a thing. After building numerous chatbots, she started looking for other types of interfaces that made sense for AI agents and landed on spreadsheets. “I had this personal pattern, and I noticed that a lot of other people had this pattern, of putting very important CRM data in spreadsheets just because it was the most flexible thing,” Monaco told TechCrunch. “But it was actually a pain to maintain. There’s so muc

Unlocking Real-Time Supply Chain Analytics with GPU Technology: Q&A with Meher Siddhartha Errabolu

As supply chains generate ever-larger datasets and demand faster decisions, traditional central processing unit (CPU)-based systems are approaching their limits. To meet real-time requirements at scale, developers turn to accelerated computing powered by graphics processing units (GPUs). These massive parallel processors reshape how data is accessed, analyzed, and operationalized across the enterprise supply chain. One expert at the forefront of this transformation is Meher Siddhartha Errabolu.

There’s Something Really Suspicious About the Way This Star Died

Stellar death is a complex and mysterious process — but in the case of a supernova known as 2023zkd, things were more gruesome than any astronomer had ever seen before. As its name suggests, this supernova — the fabulous astronomical term for the explosive death of a star — was first spotted back in 2023, when Southern California's Zwicky Transient Facility zeroed in on it thanks to new AI algorithms designed to detect such brilliant blasts. This supernova, however, was different. It appeared,

While the iPhone 16e was expected to be essentially a new SE model, Apple rebranded and upgraded it

This vintage ‘Apple Watch’ face needs to exist

Apple has designed all sorts of Apple Watch faces in the 10+ years since the product launched. Still, there’s one face that Apple should build and release as soon as possible, please. That face, of course, is the one from the “Apple” watch that predated Apple Watch by two decades. The anonymous X account that goes by the name System Settings has designed their take on how it could look: i designed a watch face inspired by this vintage Apple Watch what do you think 👀 https://t.co/N6k4YCmw1u

I love my Samsung Z Fold 7, but these Google Pixel upgrades would win me over

The Google Pixel 9 Pro Fold (left) competed with the Samsung Galaxy Z Fold 6 (right) last summer. Kerry Wan/ZDNET ZDNET's key takeaways The Google Pixel 10 Pro Fold is expected to launch on August 20, but it might not go on sale till October 9. It will be difficult for Google to beat Samsung in the foldable segment this year due to design differences. Unless there's an actually useful AI feature or significantly better battery life, I'll stick with my Galaxy Z Fold 7. Get more in-depth ZDNE

Should you replace a traditional Wi-Fi router with mesh? I compared the two, and here's my verdict

Maria Diaz/ZDNET With the adoption of remote and hybrid working, having a reliable internet connection at home is imperative -- not just for one device, but for several. If you have a family, maybe even dozens. So what's better, one single access point, or a mesh network spread about the home? The answer depends on how your home and office are set up and what kind of connection you need. Wi-Fi routers are so good these days that a single access point is often the most straightforward solution.

Patients trust AI's medical advice over doctors - even when it's wrong, study finds

TEK IMAGE/SCIENCE PHOTO LIBRARY / Science Photo Library via Getty Images ZDNET's key takeaways People can't tell AI-generated from doctor responses. However, people trust AI responses more than those from doctors. Integrating AI into clinical practice must be a nuanced approach.

Typechecker Zoo

This is a pet project of mine I’ve been working on for a while. We’re going to create minimal implementations of the most successful static type systems of the last 50 years. This will involve making toy implementations of programming languages and the core typechecking algorithms. These obviously have evolved a lot over the years, so we’ll start with the simple ones and proceed all the way up to modern dependent types. Basically a fun romp through half a century of programming language design.

Texas law gives grid operator power to disconnect data centers during crisis

Dive Brief: Data centers and other large, non-critical power consumers connected to the Electric Reliability Council of Texas transmission grid must accept curtailment during firm load shed events under a landmark law Republican Gov. Greg Abbott signed Friday. Senate Bill 6 pairs mandatory curtailment with a voluntary demand response procurement program under which loads of 75 MW or more could ramp down or switch to backup generation at utilities’ request. It also includes new interconnection

95% of AI Pilots Failing

Good morning. Companies are betting on AI—yet nearly all enterprise pilots are stuck at the starting line. The GenAI Divide: State of AI in Business 2025, a new report published by MIT’s NANDA initiative, reveals that while generative AI holds promise for enterprises, most initiatives to drive rapid revenue growth are falling flat. Despite the rush to integrate powerful new models, about 5% of AI pilot programs achieve rapid revenue acceleration; the vast majority stall, delivering little to

Logitech May Soon Prove if It Made the Best Mouse Even Better

Using Logitech’s MX Master mouse can feel like you’re slipping your hand into a cradle form-fitted to your palm. Even if the MX Master lineup has been consistently good, the MX Master 3 proved such a staple that some users continue to flit around on their 8-year-old mouse even as it disintegrates between their aging fingers. Logitech may finally have the update we’ve been waiting for with an MX Master 4. Logitech doesn’t have to change much for it to be one of the best productivity mice once aga

Better than Ray-Bans? Meta Could Unveil 'Hypernova' Glasses Next Month

September is gearing up to be one of the most exciting months of the year for new technology launches, with Meta reportedly set to unveil its next-generation smart glasses. Codenamed Hypernova, according to Bloomberg, the glasses are set to start around $800 for the basic model -- that's at least $200 less than previously thought.
