PSR J0125−5854 is a neutron star spinning roughly forty times per second, locked in an 833-day orbit with the burned-out core of a star whose outer envelope it long ago pulled away.
The bootlace worm (Lineus longissimus), washed up on British beaches after storms, has been measured at up to 55 metres long — longer than any blue whale — and secretes a neurotoxin, nemertide α-1, potent enough to paralyse crabs and kill cockroaches on contact.
The first dinosaur ever confirmed from Antarctica had been sitting in a drawer for forty years.
The proposition that another animal species besides humans uses personal names was, for essentially the entire history of comparative animal cognition research before the 1960s, considered a category error.
The Boomerang Nebula, a Sun-like star in its death throes about 5,000 light-years away, has cooled itself below the leftover heat of the Big Bang. The mechanism is the same one that runs your refrigerator.
The gas in birthday balloons was read off the Sun before anyone proved it existed on Earth, and the claim was doubted for more than a decade.
Cameras on the deep seafloor finally caught the defense in the act, and it works almost the instant a predator commits to the bite.

Every other animal with a backbone carries oxygen on the red pigment hemoglobin. One family of Antarctic fish lost it entirely, and the strange engineering that keeps them alive has made them one of biology's favorite natural experiments.
Open any device built in the past five years, look inside its memory subsystem, and the chips you find were almost certainly fabricated in one of three South…
Chung's pitch to the British financial establishment in the autumn of 1971 was, by every reasonable measure of the available business case, absurd.
Microsoft's headline number is striking: in a new diagnostic benchmark, its experimental MAI Diagnostic Orchestrator, or MAI-DxO, correctly solved up to 85.5 percent of 304 difficult medical cases adapted from the New England Journal of Medicine.
On the edge of an ancient river valley in Jezero crater, at an outcrop the mission team named Bright Angel, NASA's Perseverance rover ran its instruments…
On July 1, 2025, the ATLAS survey telescope in Rio Hurtado, Chile, reported a faint moving object to the Minor Planet Center.
For most of the twentieth century, the rule seemed simple. You are born with all the neurons you will ever have, and the adult brain makes no new ones.
