Lego-style propaganda videos alleging war crimes are flooding online feeds, echoing the White House’s own turn toward cryptic teaser clips and meme-native visuals. This is not just content drift. It is a new front in the information war, one where speed, ambiguity, and algorithmic reach matter as much as accuracy.One Iran-linked outlet, Explosive News, can reportedly turn around a two-minute synthetic Lego segment in about 24 hours. The speed is the point. Synthetic media does not need to hold up forever; it only needs to travel before verification catches up.Last month, the White House added to that confusion when it…

SiFive, a company founded in 2015 by the UC Berkeley engineers who created an open source chip design, has landed a $400 million oversubscribed round that values the company at $3.65 billion. This deal is interesting for a bunch of reasons. For one, SiFive’s RISC-V open chip design is based on the RISC processor, not Intel’s x86 or ARM, the two major types of CPUs that currently feed Nvidia’s GPU computer system AI empire. Also, Nvidia was investor in this round, alongside a long list of VCs, private equity, and hedge funds. The round was led by Atreides Management, founded…

Amid horrific threats from United States president Donald Trump as the US and Iran negotiated a ceasefire, the US government warned this week that Iran-linked hackers were carrying out attacks against US energy and water infrastructure targets. With nearly one in five people in Lebanon displaced by Israeli attacks, the government is attempting to manage the crisis without modern digital infrastructure and an emergency system that is barely hanging on. Plus, a WIRED analysis looked at Syrian government account hijacks in March and the inadequacies they expose in Syria’s baseline cybersecurity defenses.Amid rising fears of political violence, a WIRED investigation…

I will say that I think this product could be neat in a few scenarios. If you like to dye your own extensions, or you continually change the color of a streak and don’t need to buy oodles of full-size dye containers, or you’re a parent with kids that are always dip-dying their bleached ends, then it might make sense. And the resulting product does smell good. I also like the included container that lets you store leftover dye. If you’re specifically seeking washed-out, pastel tones, I still think you should just … get some hair dye and dilute it…

Five hundred bucks. That’s the price difference between the MacBook Neo and the MacBook Air. Having spent a lot of time testing and using both laptops in the MacBook lineup, I can say that there’s a clear demographic for both of these devices.As a longtime laptop tester, my goal here is twofold. I want to make sure that you buy the right MacBook, and I also want to make sure you don’t overpay or underbuy. Deciding isn’t actually as difficult as you might think. Don’t think you want a MacBook after all? Don’t forget to check out our guides to…

Specialized’s proprietary, 700-watt motor feels natural—sometimes to an annoying extent, as the bike is designed for you to pedal and you won’t get faster than 10 mph just by using the throttle. Also, there’s no option for a dual battery. Still, the battery well exceeded Specialized’s estimated 60-mile range. Granted, I am a small person, but I was usually hauling at least one other person on the bike with me at all times, so I still found this remarkable.It’s easily adjustable—both my 5’10” husband and my 5’2″ self were able to switch off riding, which is important if this is…

Infectious diseases borne by mosquitoes—such as malaria, dengue fever, and Zika fever—claim more than 770,000 lives worldwide each year. Understanding how mosquitoes find humans has long been a challenge in controlling the spread of these diseases. However, little has been known about how mosquitoes integrate multiple cues, including visual information and carbon dioxide, to approach their targets.In this context, a research team led by the Georgia Institute of Technology and Massachusetts Institute of Technology has succeeded in automatically deriving a dynamic model governing mosquito flight by applying Bayesian inference statistical methods to a vast amount of data recording mosquito movements.Bayesian…

Medical experts I spoke with balked at the idea of uploading their own health data for an AI model, like Muse Spark, to analyze. “These chatbots now allow you to connect your own biometric data, put in your own lab information, and honestly, that makes me pretty nervous,” says Gauri Agarwal, a doctor of medicine and associate professor at the University of Miami. “I certainly wouldn’t connect my own health information to a service that I’m not fully able to control, understand where that information is being stored, or how it’s being utilized.” She recommends people stick to lower-stakes, more…

Even after a few hours I don’t mind the weight, and they work just fine with sunglasses and hats. They include a reflective neck strap that pops onto the arm end of each bud, but it isn’t particularly comfortable, and it’s stiff enough that those with larger necks will find it restrictive. Once I have them in the right spot they feel secure, so I don’t feel the need to deploy the strap even when working in the yard.Battery life hasn’t been an issue at all, with Asus quoting the headset at 16 hours, with 48 additional hours in the…

Health and Human Services secretary Robert F. Kennedy Jr. has pursued an aggressive overhaul of federal vaccine guidance and infrastructure since he took office a little over a year ago. Now, his agenda is on hold after a federal judge blocked many of those changes and as reports surface that the White House is reining in his anti-vaccine rhetoric ahead of the midterm elections.What’s next for US vaccine policy will depend on the outcome of a federal court case, and whether Kennedy is allowed to resume his crusade against vaccines after November. Even if the Trump administration pivots to a…

After 10 days, the four astronauts aboard the Orion spacecraft have returned to Earth, their mission around the Moon a success. Integrity, the name of the crew’s spacecraft as part of NASA’s Artemis II mission, splashed down in the Pacific Ocean off the coast of San Diego, California, at 5:07 p.m. Pacific Time, according to NASA. The four crew members aboard — three Americans and one Canadian — were all in “green” (or safe and healthy) condition after the Orion craft’s “perfect” landing. The crew was composed of Commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and…

The farthest journey in human history concluded Friday evening when NASA’s Artemis II astronauts returned to Earth after a flight around the moon. The crew’s Orion space capsule named Integrity splashed down in the Pacific Ocean off the coast of San Diego shortly after 5 pm Pacific Time, marking the end of a 10-day, more than 695,000-mile voyage beyond the lunar far side and back.The four-person crew of Artemis II—commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch, and mission-specialist Jeremy Hansen—traveled a greater distance from Earth than ever before, reaching 252,756 miles from our home planet.“We most importantly…

The unique Škoda DuoBell bicycle bell is a classic example of a completely analog solution to a problem caused by digital innovation. Its ringing sound bypasses the noise-canceling capabilities of modern headphones, which often isolate the wearer from outside noises all too well.People with headphones using active noise cancellation are often left in a perceptive bubble where they fail to react—or simply react too late—to imminent dangers on streets and sidewalks they can’t hear coming. The DuoBell’s mission is precisely to make itself heard even beyond the latest-generation barrier filters.Ring BlingTo design the DuoBell’s ANC-defeating capabilities, researchers from the Czech…

Over the last several years, fusion power has gone from the butt of jokes — always a decade away! — to an increasingly tangible and tantalizing technology that has drawn investors off the sidelines. The technology may be challenging to master and expensive to build today, but fusion promises to harness the nuclear reaction that powers the sun to generate nearly limitless energy here on Earth. If startups are able to complete commercially viable fusion power plants, then they have the potential to upend trillion-dollar markets. The bullish wave buoying the fusion industry has been driven by three advances: more…

This week, our hosts discuss why OpenAI and Elon Musk’s legal feud is heating up once again—and happening alongside SpaceX’s IPO filing. They also dive into how a Department of Justice lawyer misled a judge about how they’re handling voter data, and why the Artemis II’s launch captured all of our imaginations.Articles mentioned in this episode:You can follow Brian Barrett on Bluesky at @brbarrett and Leah Feiger on Bluesky at @leahfeiger.
