A revolutionary eDNA test detects endangered hammerhead sharks using genetic traces left in seawater, eliminating the need to capture or even see them. This powerful tool could finally uncover where these elusive species still survive, and help protect them before they disappear for good.

Nvidia has agreed to buy assets from Groq, a designer of high-performance artificial intelligence accelerator chips, for $20 billion in cash, according to Alex Davis, CEO of Disruptive, which led the startup's latest financing round in September. From a report: Davis, whose firm has invested more than half a billion dollars in Groq since the company was founded in 2016, said the deal came together quickly. Groq raised $750 million...

What are you willing to do to get your hands on DDR5 memory these days? Whatever it is, it probably doesn't match the lengths these Russian modders are reaching by trying to build their own RAM. You can actually follow along with your own parts, along with a bit of time to solder the memory ICs to the PCB. Read more ›

The Trump administration has announced it would replace the lottery programme used to grant H-1B visas for skilled foreign workers with a system that prioritises higher-paid individuals. From a report: The Department of Homeland Security said it would begin to implement a "weighted" selection process to give an advantage to higher-skilled and higher-paid applicants from February, according to a statement posted on its website.

Editor’s note, December 25, 8 am ET: This story is being republished for the holiday season. It was originally published in 2024. When I was about 7, Los Angeles public schools shifted to a “year-round” schedule. The effect, for my elementary school, was a shorter summer break (boo), and an extra-long winter break (also, it […] Read more ›

When your kid starts showing a preference for one of their stuffed animals, you're supposed to buy a backup in case it goes missing. I've heard this advice again and again, but never got around to buying a second plush deer once "Buddy" became my son's obvious favorite. Neither, apparently, did the parents in Google's […] Read more ›

After a successful 2024 election, Vice President JD Vance came into the White House ready to shake things up, support President Donald Trump at all costs, and post whatever he wanted online. But what does Vance — the former “never Trump” conservative who has maneuvered, at least for now, into the position of MAGA heir […] Read more ›

A major international review has upended long-held ideas about how top performers are made. By analyzing nearly 35,000 elite achievers across science, music, chess, and sports, researchers found that early stars rarely become adult superstars. Most world-class performers developed slowly and explored multiple fields before specializing. The message is clear: talent grows through variety, not narrow focus. Read more ›

The familiar fight between “mind as software” and “mind as biology” may be a false choice. This work proposes biological computationalism: the idea that brains compute, but not in the abstract, symbol-shuffling way we usually imagine. Instead, computation is inseparable from the brain’s physical structure, energy constraints, and continuous dynamics. That reframes consciousness as something that emerges from a special kind of computing matter, not from running the right program. Read more ›

A new AI developed at Duke University can uncover simple, readable rules behind extremely complex systems. It studies how systems evolve over time and reduces thousands of variables into compact equations that still capture real behavior. The method works across physics, engineering, climate science, and biology. Researchers say it could help scientists understand systems where traditional equations are missing or too complicated to write down. Read more ›

New research suggests Alzheimer’s may start far earlier than previously thought, driven by a hidden toxic protein in the brain. Scientists found that an experimental drug, NU-9, blocks this early damage in mice and reduces inflammation linked to disease progression. The treatment was given before symptoms appeared, targeting the disease at its earliest stage. Researchers say this approach could reshape how Alzheimer’s is prevented and treated. Read more ›

For years, scientists thought Saturn’s moon Titan hid a global ocean beneath its frozen surface. A new look at Cassini data now suggests something very different: a thick, slushy interior with pockets of liquid water rather than an open sea. A subtle delay in how Titan deforms under Saturn’s gravity revealed this stickier structure. These slushy environments could still be promising places to search for life. Read more ›

A small tweak to mitochondrial energy production led to big gains in health and longevity. Mice engineered to boost a protein that helps mitochondria work more efficiently lived longer and showed better metabolism, stronger muscles, and healthier fat tissue. Their cells produced more energy while dialing down oxidative stress and inflammation tied to aging. The results hint that improving cellular power output could help slow the aging process itself.

Researchers have revealed that so-called “junk DNA” contains powerful switches that help control brain cells linked to Alzheimer’s disease. By experimentally testing nearly 1,000 DNA switches in human astrocytes, scientists identified around 150 that truly influence gene activity—many tied to known Alzheimer’s risk genes. The findings help explain why many disease-linked genetic changes sit outside genes themselves. The resulting dataset is now being used to train AI systems to predict... Read more ›

Long before whales and sharks, enormous marine reptiles dominated the oceans with unmatched power. Scientists have reconstructed a 130-million-year-old marine ecosystem from Colombia and found predators operating at a food-chain level higher than any seen today. The ancient seas were bursting with life, from giant reptiles to rich invertebrate communities. This extreme complexity reveals how intense competition helped drive the evolution of modern marine ecosystems. Read more ›

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made over 100 years ago and reveals new clues about how black holes spin and launch jets. Read more ›

Researchers have found that fossilized dinosaur eggshells contain a natural clock that can reveal when dinosaurs lived. The technique delivers surprisingly precise ages and could revolutionize how fossil sites around the world are dated. Read more ›
