Ageing is often described as a slow accumulation of damage, but a new study suggests something more subtle may be happening inside our cells. Researchers at University of California, San Francisco report that as cells grow older, they do not simply wear out, they lose the coordinated gene activity that keeps them functioning efficiently. By…
A rocket launch looks like a contest between raw power and engineering control, but the most critical moments happen before the vehicle even leaves the ground. In the final seconds on the launchpad, forces build rapidly as engines ignite while the rocket is still restrained. To an outside observer, some of the systems activated at…
NASA tests space sensors for tracking ocean debris (AI-generated) Scientists at NASA are beginning to look at ocean debris from an unfamiliar angle, not from ships or beaches, but from orbit. The work follows a recent finding that space based sensors can detect plastic pollution on land, a result that has quietly shifted expectations. Rather…
The idea of dark matter has existed for decades, mostly as a necessary explanation rather than something clearly seen. New observations from the James Webb Space Telescope are adding texture to that idea, without resolving it completely. Scientists working with Webb data have produced a detailed map showing where dark matter appears to sit in…
Distant planets once linked to oceans may be full of magma (AI-generted) Astronomers have spent the past decade cataloguing thousands of planets beyond the solar system, many of them falling into a strange middle category. These worlds, known as sub Neptunes, are larger than Earth but smaller than Neptune, and they appear everywhere modern telescopes…
The total solar eclipse of August 12, 2026, will sweep across parts of the northern hemisphere, briefly turning day into dusk along a narrow path. Greenland, Iceland, and northern Spain will lie directly beneath the moon’s shadow, while much of Europe, Scandinavia, West Africa, and parts of North America will see a partial eclipse. Timings…
Imagine a great, green rainforest thriving inside the icy land that exists today. It might sound like science fiction, but research shows that Antarctica was once warm enough to host temperate rainforests near the South Pole about 90 million years ago. A scientific study published in PubMed Central, titled “Temperate rainforests near the South Pole…
ChatGPT ‘nearly kills’ woman after giving confident advice about a poisonous plant/ (@rawbeautybykristi/Instagram) Millions of people now treat AI chatbots as a first stop for everyday questions, from recipes to home projects. But one YouTuber has warned that misplaced trust in those answers can be dangerous, after her best friend was repeatedly reassured by ChatGPT…
Astronomers identify a possible massive moon with water orbiting a distant world (AI-generated) Astronomers are testing a quieter way of searching for moons beyond the solar system, using careful measurements of motion rather than changes in light. A new study focuses on HD 206893 B, a substellar companion about 133 light years from Earth, already…
Ants may be small, but they are quite rugged, especially in the face of extreme stressful situations like nuclear radiation. While human beings are known to be adversely affected by illness and health hazards caused by doses of radiation, ants seem to be rather less bothered. Studies have shown us that there are biological mechanisms…
