Autism Is Not a Single Condition and Has No Single Cause, Scientists Conclude

New research from the University of Cambridge suggests that autism should not be understood as a homogeneous condition with a single cause. Scientists found that people diagnosed in early childhood often have a different genetic profile than those diagnosed later in life, broadening the understanding of how the condition develops. The study analyzed the behavior of autistic people during childhood and adolescence in the United Kingdom and Australia. It also evaluated genetic data of more than 4

Best Bike Helmets (2025), Tested and Reviewed

Of all the helmets on this list, the Closca Loop looks the most futuristic, like something out of Spike Jonze’s set-in-the-not-too-distant-future dystopian romantasy Her. It features a design that is elegant yet understated and one that certainly doesn’t give the appearance of something that can do so much more than protect your head. That is, of course, when it’s unfolded and therefore wearable. With a bit of pressure on the top of the Loop, the helmet collapses down into itself (think one of t

AMD teams up with OpenAI to challenge Nvidia’s AI chip dominance

Posts from this author will be added to your daily email digest and your homepage feed. AMD is partnering with OpenAI to provide six gigawatts worth of processors for AI data centers, a move that challenges Nvidia’s AI chip market dominance. The five-year agreement aims to help OpenAI bolster its infrastructure to meet growing computational demands for AI applications like ChatGPT, starting with a gigawatt deployment of AMD Instinct MI450 GPUs in the second half of 2026, according to AMD’s pres

Social Cooling (2017)

3. Increased social rigidity Digital reputation systems are limiting our ability and our will to protest injustice. In China each adult citizen is getting a government mandated "social credit score". This represents how well behaved they are, and is based on crime records, what they say on social media, what they buy, and even the scores of their friends. If you have a low score you can't get a government job, visa, cheap loan, or even a nice online date. Social pressure is the most powerful

The death of industrial design and the era of dull electronics

It’s often said that what’s inside matters more than one’s looks, but it’s hard to argue that a product’s looks and its physical user experience are what makes it instantly recognizable. When you think of something like a Walkman, an iPod music player, a desktop computer, a car or a TV, the first thing that comes to mind is the way that it looks along with its user interface. This is the domain of industrial design, where circuit boards, mechanisms, displays and buttons are put into a shell that

Megafauna was the meat of choice for South American hunters

The extinction of the Pleistocene megafauna may be people’s fault after all, according to a recent study. A team of archaeologists recently examined animal bones at sites dating to the waning years of the last Ice Age. Their results suggest that extinct megafauna like giant sloths, giant armadillos, and elephant-like creatures were on the menu for Pleistocene hunters in South America. And that means human hunters may have played a nontrivial role in killing off the continent’s last great Ice Ag

Hungry Rogue Planet Is Gobbling Gas and Dust at 6 Billion Tons per Second

Rogue planets live by their own rules, freely floating through the cosmos without being bound to a star. With no stellar supervision, those isolated planetary bodies can often behave in unusual ways. Astronomers discovered a rogue planet experiencing a rather unusual growth spurt, bingeing on its surrounding gas and dust at an unprecedented rate. The rogue planet is located approximately 620 light-years away in the Chameleon constellation. It’s still in its early formation process and is feedin

The Mystery of How Quasicrystals Form

The original version of this story appeared in Quanta Magazine. Since their discovery in 1982, exotic materials known as quasicrystals have bedeviled physicists and chemists. Their atoms arrange themselves into chains of pentagons, decagons, and other shapes to form patterns that never quite repeat. These patterns seem to defy physical laws and intuition. How can atoms possibly “know” how to form elaborate nonrepeating arrangements without an advanced understanding of mathematics? “Quasicrysta

Lazy Parents Are Giving Their Toddlers ChatGPT on Voice Mode to Keep Them Entertained for Hours

Our society has only recently come to terms with the fact that maybe placating young children by getting them hooked on touchscreen devices with unfettered access to the internet was bad for their brains. Now, with the rise of human-like AI chatbots, a generation of “iPad babies” could seem almost quaint: some parents are now encouraging their kids to talk with AI models, sometimes for hours on end, The Guardian reports. Others are using the soothing voice of a chatbot to put their kids to bed

Personal data storage is an idea whose time has come

Data Ownership as a conversation changes when data resides primarily with people-governed institutions rather than corporations. Back in 2009 Tim Berners-Lee drafted a web-specification for "Socially Aware Cloud Storage": There is an architecture in which a few existing or Web protocols are gathered together with some glue to make a world wide system in which applications (desktop or web application) can work on top of a layer of commodity read-write storage. Crucial design issues are that

You Are Not Prepared for Merriam-Webster’s Announcement of Its New AI Model

Everything is getting stuffed with AI these days, no matter how pointless its inclusion may seem. Your spell-checker, your local drive-thru, your fridge — nothing is safe. So you can understand why we were alarmed when Merriam-Webster, the dictionary company, announced that it was releasing its own large language model, too. “It is the dawn of the AI era,” says a narrator in a video shared by the company. “And we are proud to introduce our latest large language model.” “It never hallucinates.

Study confirms that pianists can shape piano timbre through touch

Summary: A new study has scientifically confirmed that pianists can change piano timbre mid-performance through touch alone. Using high-speed sensors, researchers captured key movements and showed that subtle differences in motion aligned with the timbre that listeners perceived. The findings prove that timbre manipulation isn’t just a metaphor, but a skill rooted in precise motor control. Beyond music, this discovery highlights how refined body movement can shape artistic expression, with pote

Newsom signs bill giving Uber and Lyft drivers in California the right to unionize

In Brief Drivers for ride-hailing apps like Uber and Lyft will soon have the right to unionize in California as independent contractors, thanks to a bill signed Friday by Governor Gavin Newsom. This is part of a larger deal between lawmakers, unions, and ride-hailing companies, resulting in the passage of separate bills supporting lower insurance requirements for Uber and Lyft, along with union rights for their drivers. When the deal was first announced in August, Newsom described it as an “hi

Bezos predicts that millions will live in space in ‘couple of decades’

In Brief Amazon founder Jeff Bezos made a rare public appearance at Italian Tech Week in Turin on Friday and used the opportunity to predict that millions of people will be living in space “in the next couple of decades,” the Financial Times reports. Speaking with John Elkann, a scion of Italy’s Agnelli dynasty, Bezos, who also founded rocket company Blue Origin, insisted people will be living in space “mostly because they want to,” and that robots will handle the grunt work, while vast AI dat
