Anthropic just published a study mapping exactly which jobs its own AI is replacing right now. The workers most at risk are not who anyone expected. They are older. They are more educated. They earn 47% more than average. And they are nearly four times more likely to hold a graduate degree than the workers AI is not touching. The argument is straightforward. Anthropic built a new metric called "observed exposure." Not what AI could theoretically do. What it is actually doing right now in professional settings, measured against millions of real Claude conversations from enterprise users. For computer and...

Both eruptions came from a sunspot region on the sun's western limb, AR4419. The first solar flare peaked at 9:07 p.m. EDT on April 23 (0107 GMT April 24), followed by the second at 4:14 a.m. EDT (0814 GMT) on April 24. These are the strongest solar flares we've seen in 78 days, according to solar physicist Ryan French. The bursts of radiation from the flares triggered strong radio blackouts on the sunlit side of Earth — the first affecting parts of the Pacific Ocean and Australia and the second impacting East Asia. The active sunspot region is putting on...

It was more than it was Kraken-ed up to be. An octopus the size of the Hollywood Sign might seem like a monster from Greek mythology. However, new fossil evidence reveals that massive “kraken”-like cephalopods ruled the seas during the Cretaceous period, possibly preying on massive sea reptiles and other so-called apex predators, per a study published Thursday in the American Association for the Advancement of Science. This massive mollusk “had among the largest body sizes of all organisms in the Cretaceous oceans,” wrote the researchers, who hailed from Hokkaido University. Indeed, at 62-feet-long, this colossal octopus could grow up...

With all the excitement over sending scientists back to the moon, it’s easy to forget we’ve already got a pair of talented chemists on Mars: the Curiosity and Perseverance rovers. Although they beam back plenty of breathtaking images, these two robots are more than just cameras on wheels. Their primary mission is to search for signs of ancient life, and they’re equipped with a suite of onboard scientific instruments and chemical reagents to carry that mission out. Now, new research published in Nature Communications details Curiosity’s latest find—never-before-seen organic compounds, including one with a structure similar to DNA precursors. “We...

This innovative gel can be quickly applied to teeth in much the same way as standard fluoride treatments. Unlike traditional products, it contains no fluoride. Instead, it is made from proteins that imitate those naturally responsible for guiding enamel formation early in life.Once applied, the gel forms a thin yet durable layer that seeps into the surface of the teeth, filling in tiny cracks and holes. It then acts as a scaffold that captures calcium and phosphate ions from saliva. These minerals are carefully organized into new enamel through a process known as epitaxial mineralization. This allows the regenerated enamel...

51 years ago, India marked a historic milestone with the launch of Aryabhata, its first step into space. But long before the satellite lifted off aboard a Soviet rocket, its story had already begun in an unlikely place: a small church by the Arabian Sea. In the early 1960s, India’s fledgling space programme, what would later become the Indian Space Research Organisation, was operating with limited resources but boundless ambition. Under the leadership of Vikram Sarabhai, scientists were searching for a location close to the magnetic equator to study the upper atmosphere. They found it in Thumba, a quiet fishing...

It’s the end of the world as we know it — a lot sooner than we think. A team of researchers have drastically scaled back the going estimate of how long it will be until the universe ceases to exist. Previously, scientists believed it would be 10¹¹⁰⁰ years until the very last objects in the cosmos would disappear forever — that’s a 1 followed by 1,100 zeroes, in layman’s terms. But a new study published in the Journal of Cosmology and Astroparticle Physics by a trio of researchers at Radboud University in the Netherlands posits the real figure as closer...

Garcia allegedly served as a property custodian at KCNSC's New Mexico facility, giving him a top security clearance and broad access to the entire site's nuclear secrets. The source described Garcia's work as 'a very high-level, overseeing position for all the assets. Tens, maybe hundreds of millions of dollars in equipment and assets, some of which are not classified, others would be classified.' The government contractor's sudden disappearance marks the tenth person with ties to America's space or nuclear secrets who has died or mysteriously vanished in recent years, putting US national security experts on edge.

A simple experiment in a child’s swimming pool allows you to visualize the angular momentum of rotating waves. Beautifully done.

It may seem surprising that researchers could study a phenomenon for which we don’t yet have any data—after all, there are no verified accounts of conversations with aliens. But there are good reasons to consider what alien languages might look like. For one... human languages have far more in common than we might think. A universal grammar underlies what turn out to be mostly surface differences. [A]ll languages use a finite number of sounds (or gestures in the case of signed languages) and phrase types (like noun phrases and verb phrases) to build a theoretically limitless number of unique communications,...

Lunar Starship (the Starship Human Landing System, or HLS, for NASA's Artemis program) is in active development but remains several years from its first crewed lunar landing. As of early April 2026, the program has made substantial progress on hardware testing and subsystem qualification, yet key challenges like in-orbit propellant transfer, long-duration flights, and an uncrewed lunar demonstration are still ahead—contributing to schedule delays. Current Status and Major Achievements SpaceX has completed 49 contractual milestones for the HLS contract with NASA (out of many total), with most achieved on or ahead of schedule. These cover: Life support and thermal control...

Near-Earth asteroid Apophis is a potentially hazardous asteroid that will safely pass close to Earth on April 13, 2029. It will come about 20,000 miles (32,000 kilometers) from our planet’s surface — closer than the distance of many satellites in geosynchronous orbit (about 22,236 miles, or 36,000 kilometers, in altitude).

The machine is technically called PUPER, which stands for “preservation of the uterus in perfusion.” But González’s colleague Xavier Santamaria says the team has adopted a nickname for it: “We call it ‘Mother.’” He sees a future in which a machine like “Mother” will be able to fully gestate a human, all the way from embryo to newborn. It could offer a new path to parenthood for people who don’t have a uterus, for example, or who are not able to get pregnant for other reasons.

A series of fireballs — very bright meteors — were spotted across North America from March 17-23, 2026. People in Ohio reported one on March 17. The next sightings were in California on March 19, Michigan and Georgia on March 20, and Texas on March 21, where a fragment crashed through a house roof. It's happening beyond the U.S. Vancouver saw a fireball on March 3. France and Germany reported sightings on March 8 and 11. Many fireballs lasted a long time and were seen across wide areas. Some caused pressure waves and sonic booms. ... The emerging picture is...

The astronaut who prompted NASA’s first medical evacuation earlier this year said Friday that doctors still don’t know why he suddenly fell sick at the International Space Station. Four-time space flier Mike Fincke said he was eating dinner on Jan. 7 after prepping for a spacewalk the next day when it happened. He couldn’t talk and remembers no pain, but his anxious crewmates jumped into action after seeing him in distress and requested help from flight surgeons on the ground. ... Fincke, 59, a retired Air Force colonel, said the episode lasted roughly 20 minutes and he felt fine afterward....

“A string of deaths and disappearances involving individuals linked to United States defence and aerospace research has ignited intense speculation online, with some claiming a hidden connection to classified programmes. In less than a year, six scientists and researchers tied to high-level projects have either died or gone missing, raising questions but also prompting experts to urge caution over unverified claims. The cases span from mid-2025 to early 2026 and involve individuals connected to agencies such as US Air Force Research Laboratory, NASA Jet Propulsion Laboratory, and Los Alamos National Laboratory. One of the earliest cases is Monica Jacinto Reza,...

The possible arrival time for the incoming solar storms is still evolving, and depends on which of the multiple CMEs strike Earth and what effect they have. According to NOAA's latest forecast, the first impacts could begin as early as 11 p.m. EDT March 18 (0300 GMT March 19), with moderate (G2) geomagnetic storm conditions most likely between 2:00 a.m. and 8 a.m. EDT (0600-1200 GMT). However, other models, including those cited by the U.K. Met Office, suggest the main CME could arrive later on March 19 or even early March 20, prolonging auroral activity through the weekend. Because multiple...
