Archaeologists have identified the world’s oldest-known poisoned arrowheads, pushing back the timeline of complex human hunting strategies to nearly 60,000 years ago. The discovery comes from Umhlatuzana Rock Shelter in KwaZulu-Natal, South Africa, where researchers...

Scientists have achieved a long-sought milestone in plant biology: they’ve captured live, real-time footage of plants “breathing,” showing microscopic pores opening and closing as gases move in and out. Researchers at the University of Illinois...

For decades, Mars has been defined by what it lacks: liquid water, a thick atmosphere, and the conditions needed to sustain life. But a new study by Swiss scientists is adding weight to a radical...

Astronomers studying a nearby dead star have stumbled upon something they did not expect and cannot yet fully explain. A glowing, rainbow-shaped bow shock surrounding the white dwarf RXJ0528+2838, located about 731 light-years from Earth,...

An asteroid spinning once every 1.88 minutes should not exist in one piece. Yet that is exactly what astronomers are observing in the main asteroid belt, following new detections by the Vera C. Rubin Observatory....

For decades, Alzheimer’s research has largely revolved around one culprit: toxic protein buildups in the brain, especially amyloid-beta plaques. While that approach has delivered modest progress, it has also left major gaps, particularly for women...

Pancreatic cancer is one of medicine’s most unforgiving diagnoses. It hides in plain sight, produces vague symptoms, and is often discovered only when treatment options are limited. Now, an artificial intelligence system developed in China...

For decades, it existed as a ghost in academic footnotes. An enormous stone Olmec Cave mask, sacred to one of the earliest civilisations in the Americas, vanished from Mexico sometime in the early 20th century....

Palaeontologists studying a tiny bird fossil from China were stunned to discover an unlikely cause of death: the animal appears to have suffocated after swallowing more than 800 rocks. The 120-million-year-old creature has now been...

Australian euthanasia activist Philip Nitschke, best known for creating the controversial Sarco pod, has unveiled a new assisted-dying device called the Kairos Kollar and disclosed that he is also developing what he calls a “suicide...
