Was the ‘American cheetah’ a cheetah at all?

An El Niño is usually expected to herald a cold end to winter in the UK – but this year could be different
Lucid dreams, when a person is aware they're dreaming and can often control them, could be induced in people who rarely experience them
A researcher’s social media post that revealed how to break part of a popular encryption protocol has gone viral. But did he really do it with just “good old paper and pencil”?
A substance found in edible sea squirts appeared to reverse several signs of aging in older mice. Plasmalogen supplements improved memory and learning, strengthened connections between brain cells, reduced inflammation, and even helped the mice grow thicker, darker hair. Researchers believe the compounds may encourage brain regeneration and protect aging synapses.
Puerto Rico’s normally rainy season has instead brought a severe and fast-growing drought. By August 25, three-quarters of the territory was in at least moderate drought, with extreme drought covering 44 percent and some areas receiving less than 20 percent of their usual rainfall. Water shortages have forced rationing, while farmers are losing crops and ranchers are running low on hay. The situation has become serious enough to trigger both local and federal disaster declarations.
MIT researchers have created bacterial “transistors” that can be wired together into living circuits capable of performing calculations and directing chemical signals. One day, these biological computers could coat plant roots or leaves, detecting environmental threats and automatically triggering defenses.
Slow breathing with a prolonged exhale made people more willing to take risks by changing heart activity and increasing the brain’s sensitivity to rewards. The findings suggest that something as simple as controlling your breath can directly influence how you evaluate choices.
Foreign states and technology firms are scrambling for data from the Ukraine war so they can train the next-generation of AI models that might be used in defence and national security
A giant iceberg measuring more than 76 square kilometers broke from Greenland’s Petermann Glacier in August 2026, marking the Arctic’s largest glacier calving event since 2020. The berg later slammed into Joe Island but survived without breaking apart, and satellites are now tracking it as it drifts through Nares Strait.
The newfound star S301 orbits the Milky Way’s supermassive black hole so closely that its view of the heavens gets twisted
Astronomers have identified a surprisingly young population of fading radio galaxies whose supermassive black holes have already switched off their powerful jets. The confirmed remnants range from about 8 to 42 million years old, suggesting many may disappear from view much faster than previously recognized. More distant remnants also seem to fade especially quickly, helping explain why they have been so difficult to detect.
