Dual interfacial H-bonding-enhanced deep-blue hybrid copper–iodide LEDs

Solution-processed light-emitting diodes (LEDs) are emerging as a promising technology for advanced solid-state lighting (SSL) and display industries, owing to their energy-efficient, low-cost, and straightforward manufacturing processes1-3. In this realm, lead-halide based perovskites4, organic semiconductors5, and colloidal core–shell quantum dots (QDs)6 have gained recognition as promising candidates. They have been utilized as emitting layers via solution processing and achieved impressive p

How the 'Minecraft' Score Became Big Business for Its Composer

In 2009, in between full-time shifts at a local factory, then-19-year-old musician Daniel Rosenfeld composed a score for an independent video game. “It was just a side hustle, maybe not even that. It was a hobby, really,” explains Rosenfeld, who records under the name C418. The game, Minecraft, turned out to be successful beyond Rosenfeld’s wildest dreams. In 2014, Microsoft purchased Minecraft’s Swedish developer, Mojang Studios, for $2.5 billion, and through 2023, it had sold 300 million copi

I'm betting against AI agents, despite building them

Everyone says 2025 is the year of AI agents. The headlines are everywhere: "Autonomous AI will transform work," "Agents are the next frontier," "The future is agentic." Meanwhile, I've spent the last year building many different agent systems that actually work in production. And that's exactly why I'm betting against the current hype. I'm not some AI skeptic writing from the sidelines. Over the past year, I've built more than a dozen production agent systems across the entire software developm

Digital vassals? French Government 'exposes citizens' data to US'

France’s deepening reliance on US tech giants is raising alarms about digital sovereignty and exposing public data to foreign jurisdictions. In a French Senate report on economic and digital sovereignty, Senators accused the French State of “political fault”. That was in regard to outsourcing essential data infrastructure to US companies subject to US extraterritorial laws, including Microsoft, despite repeated warnings and alternatives. “France is subject to US extraterritorial law,” the repo

LLM architecture comparison

It has been seven years since the original GPT architecture was developed. At first glance, looking back at GPT-2 (2019) and forward to DeepSeek-V3 and Llama 4 (2024-2025), one might be surprised at how structurally similar these models still are. Sure, positional embeddings have evolved from absolute to rotational (RoPE), Multi-Head Attention has largely given way to Grouped-Query Attention, and the more efficient SwiGLU has replaced activation functions like GELU. But beneath these minor refi

Coding with LLMs in the summer of 2025 – an update

antirez 6 hours ago. 31112 views. Frontier LLMs such as Gemini 2.5 PRO, with their vast understanding of many topics and their ability to grasp thousands of lines of code in a few seconds, are able to extend and amplify the programmer capabilities. If you are able to describe problems in a clear way and, if you are able to accept the back and forth needed in order to work with LLMs, you can reach incredible results such as: 1. Eliminating bugs you introduced in your code before it ever hits any

XMLUI

In the mid-1990s you could create useful software without being an ace coder. You had Visual Basic, you had a rich ecosystem of components, you could wire them together to create apps, standing on the shoulders of the coders who built those components. If you’re younger than 45 you may not know what that was like, nor realize web components have never worked the same way. The project we’re announcing today, XMLUI, brings the VB model to the modern web and its React-based component ecosystem. XML

Larq Bottle PureVis 2 Review: Drinking Water as a Video Game Isn’t as Dumb as It Sounds

There’s something I learned about hydration that I can never forget: if you are thirsty, you are already dehydrated. It’s a rule of thumb that can come in handy if you are out on a long hike or on the beach in the middle of summer when the risk of becoming dehydrated is pretty high. But day-to-day, I rarely pay attention to how much water I drink or how dehydrated my body could be. Despite the ever-growing popularity of mega-sized water bottles and counting the number of glasses people should d

Titan’s Methane Lakes Could Form Bubble-Like Structures Essential to Life, Scientists Say

On December 25, 2004, the Huygens probe separated from the Cassini spacecraft and landed on Titan’s sandy surface. The probe survived for 72 hours on Saturn’s largest moon, revealing a world that is chemically complex and more Earth-like than expected. For years, scientists have been intrigued by Titan as an alien world that might have the right conditions to host life, albeit in a very different form than on Earth. New research by NASA reveals that molecular precursors to life could form in Tit

James Gunn Talks Future Superman Plans, Dropping Henry Cavill

James Gunn’s spent the past few weeks talking about why he agreed to do Superman, and he’s also taking time to address the awkward part: agreeing to do it at the apparent expense of Henry Cavill’s superhero comeback. In 2022, the mid-credits scene for Black Adam none too subtly declared Cavill’s return and his team up (or fight) with Dwayne Johnson’s thunderous antihero. Nothing came of that, however, because as Gunn explained in a recent Happy Sad Confused episode, it was “never part of the eq

The Bad Batch Returns In a New ‘Star Wars’ Novel

It’s been over a year since Star Wars: The Bad Batch ended, but it was a given Clone Force 99 would eventually live on beyond the screen. Next month, we’ll check back in with the team in their first novel, Sanctuary. Written by Lamar Giles (Ruin Road), the tale takes place towards the end of season two after the episode “Pabu.” Now that they’re working with pirate hunter Phee, the Clones—Hunter, Omega, Wrecker, and Tech—are on resource gathering duty after the planet’s recent tsunami. That lead

I Get 5G on My Phone at Home, So Why Can't I Get 5G Home Internet? Here's What I Learned

If you can get 5G on your phone while at home, you should be able to get 5G internet at your house, right? Not exactly. 5G is no longer the shiny new thing, thanks to efforts from major carriers AT&T, T-Mobile and Verizon, but 5G home internet service isn't strictly available at the same addresses as 5G cellular service. I ran into this when I switched my mobile carrier from AT&T cellular service to T-Mobile phone service. I was immediately impressed with the phone's 5G performance. However, ev

13 of the Best Movies Peacock Has to Offer

Peacock is full of must-see movies. Sure, the streaming conversation is often focused on the top-tier platforms like Netflix, Disney Plus and Prime Video. But the NBC Universal-owned streamer deserves its flowers -- and I'm going to show you why. Let's talk about blockbusters for a second. Universal Pictures has been churning out box office hits and Oscar-winning flicks for more than a century. A large sampling of these titles can be found here, including the first-ever blockbuster, Jaws, among

There's an Online Community That Believes the Internet Died in 2016. Here's How AI Fits Into the Picture

It's no surprise that the rise of artificial intelligence is sparking debates among experts. Moreover, whether you use ChatGPT or Google Gemini, generative AI is increasingly being integrated into our daily lives. It's only fair to ask: Could AI take over the internet? Some members of the online community reckon it already has. This old online theory is on the rise again, and it all has to do with Shrimp Jesus. (Disclosure: Ziff Davis, CNET's parent company, in April filed a lawsuit against Open

I Tried This $40 Smartwatch: It Was Meh, but Not a Complete Waste of Time

I wasn't expecting much when I first strapped the WITHit Giga Smartwatch onto my wrist, and at least it delivered on that. This $40 smartwatch does the basics: shows notifications, counts your steps, tracks your heart rate (sort of) and lets you take calls from your wrist. But the execution of all these features is where it all starts to fall apart, and I found myself getting exactly what I paid for. After spending a week testing it, I came away with this: If you just want a basic smartwatch th

EcoFlow Introduces New Home Battery to Aid in Disaster Preparedness

Extreme weather is only becoming more common, and some states are more vulnerable to natural disasters than others. Whether it's a risk of floods, hurricanes, wildfires or blackouts, homeowners in states like California, Texas and Florida are more prone to power outages. A whole-home battery backup can be a good solution to this problem, letting you charge the battery while the power is on and then kick in when the power goes out. EcoFlow is the latest to enter this market with the Ocean Pro, wh

Shark Week 2025: How to Watch and Stream the Toothy Programming Event

Looking for sharks? You've paddled to the right place. Discovery Channel's Shark Week programming event starts tonight, bringing loads of shark-centric content for those who want to celebrate the iconic top predator. It's the kind of annual tradition that really shines on the right screen.

The first program up is Dancing with Sharks, which involves "an unprece

Here's Where to Hang Your Bird Feeder for Maximum Visits

As someone who writes about wellness and loves birdwatching, I've experienced firsthand how much joy birds can bring to your daily routine. And science backs it up. Listening to birdsong and spending time watching feathered visitors has been shown to lower stress, ease anxiety and even help reduce symptoms of depression. It's a simple but powerful way to feel more grounded and connected to nature. Until recently, I lived in an apartment in the heart of a city. I had to actively seek out nature

Southwestern drought likely to continue through 2100, research finds

The Hunt for a Fundamental Theory of Quantum Gravity

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally interwoven threads of space and time seem to stop short. These mysterious points are known as singularities. Singularities are predictions of Albert Einstein’s general theory of relativity. According to this theory, clumps of matter o

How to Limit Galaxy AI to On-Device Processing—or Turn It Off Altogether

Artificial intelligence is now more pervasive than ever in the apps and gadgets we use day to day, and that of course extends to smartphones: Google Gemini on Pixels and other Android handsets, Apple Intelligence (currently still rolling out) on iPhones, and Galaxy AI on Samsung smartphones. These tools can help you refine text, generate images, and summarize documents, among other tricks, and you don't have to go far through your apps to find an AI feature ready and willing to help you with so

Amazon’s Fire Tablets, Tested, So You Don’t Have To (2025)

The Fire HD 10 is Amazon’s best tablet. The current model dates from 2023, which means it likely will get some kind of update in 2025, but we don't expect anything more than a processor and RAM upgrade. The current Octa-core processor is plenty fast enough for everyday tasks like web browsing and watching movies, and the 3-GB of RAM helps in browsing the web with many tabs. The Fire HD 10 also has a full HD (1080p) screen, making it better for watching those Prime videos. That said, this is not

The Ultimate Dolby Atmos Experience Might Be In Your Car

It’s fair to say that no five people crammed into a compact SUV have been more blissfully enthralled on a country drive than my wife’s family and I on one particular mid-summer Sunday. It wasn’t just the silky smooth performance of the Cadillac Optiq, or even its incredible 19-speaker AKG sound system, but an x-factor pushing our driving experience beyond the sum of their parts: Dolby Atmos Music. If you haven't heard it in a vehicle like this, you might think I'm joking. Everyone has probably
