DNA reveals chemosynthesis genes in bacteria living on coral reef fish gills

Chemosynthetic bacteria have been documented in various marine environments and in association with invertebrate hosts such as annelid worms and mollusks, but their presence in fish appears to be a new discovery. The findings show that fish gills host a complex and specialized microbiome that is not yet well understood but could play an important role in fish metabolism, immunity and health.

A giant cosmic 'fart' is making a wobbling zombie star repeatedly flash us, 'groundbreaking' observations reveal

An enormous, ongoing cosmic "fart" is causing a mysterious zombie star to flare up repeatedly, shining bright pulses of X-rays toward Earth, a new study reveals. The unprecedented observations shed light on how some of the universe's most extreme objects interact with one another. Around 13,000 light-years from Earth lies an unusual binary star system, known as BP Crucis. It contains a blue hypergiant star roughly 60 times larger than the sun, dubbed Wray 977, alongside a neutron star — the undead and ultradense remains of a star that exploded via a supernova — that astronomers have labeled GX 301-2. This stellar "zombie," which contains the same mass as our home star packed into an object r...

1.7-billion-year-old fossils reveal a crucial clue to the rise of complex life

Scientists studying ancient Australian rocks uncovered more than 12,000 fossils from some of the oldest known eukaryotes on Earth. These early complex cells lived in settings ranging from coastal mudflats to the open sea, but only where oxygen was available. Oxygen-free environments contained simpler microbes instead. The findings strengthen the idea that oxygen played a crucial role in the emergence of complex life.

Why rheumatoid arthritis pain may persist even when inflammation is under control

Pain and fatigue in rheumatoid arthritis can persist even after inflammation improves, with depression, poor sleep, obesity, smoking, and chronic pain potentially helping sustain symptoms. Researchers say identifying these hidden drivers could prevent unnecessary medication changes and lead to more personalized treatment.

James Webb telescope shares one of its biggest images ever, with record-breaking stars hiding in the dust

quick factsWhat it is: IC 348, a star-forming reflection nebulaWhere it is: 1,000 light-years away in the constellation PerseusWhen it was shared: Sept. 15, 2026.Behold: one of the largest panoramas from the James Webb Space Telescope (JWST) released to date. This busy and breathtaking image offers a remarkably detailed view of IC 348, a nearby stellar nursery where astronomers are investigating some of the smallest objects produced by star formation.IC 348 is one of the closest stellar nurseries to Earth and appears in this near-infrared image as an intricate landscape of stars, glowing material and sweeping clouds of gas and dust. Across the scene, young stars punctuate the dark and lumino...

What is the closest any object has gotten to the sun?

When you think of objects close to the sun, Mercury, the solar system's innermost planet, probably comes to mind. But has any other object — natural or artificial — gotten closer to our star? And what's the closest an object has gotten to the sun while still escaping?Many objects have reached much closer than Mercury, including asteroids, comets and spacecraft, experts told Live Science.At its closest point to the sun, called perihelion, Mercury comes within 29 million miles (47 million kilometers) of our star, according to NASA. But several known asteroids come even closer. Scott Sheppard, an astronomer at Carnegie Science, an independent research institute in Washington, D.C., said such as...

These medieval graves looked like family burials. DNA told a different story

Ancient DNA shows that adults and children buried together in medieval Sweden were often not members of the same immediate family, suggesting that burial choices reflected more than biological kinship. The research also revealed early gender-based burial customs and uncovered the remarkable story of a young woman who may have completed a pilgrimage across Europe.
