Fossils

Probiotics containing Lactobacillus gasseri Lg-36 prevented C. difficile infections in mice, but L. acidophilus probiotics made infection more likely.

These star-shredding black holes sit within dusty galaxies that block many telescopes’ views. That’s not an issue for JWST.

Routine tests in the third trimester may catch missed cases and flag the need for treatment that reduces a baby‘s risk of getting HIV to near zero.

The recoded bacterium uses only 57 of the 64 possible genetic codes, freeing up seven to be used for different purposes

A trove of fossils, including a penis worm with a spiked, invertible throat, suggests this spot may have been a cradle of Cambrian evolution.

Around 8 million years ago, an ancestor of modern tomatoes in South America hydridised with a plant called Etuberosum, and this reshuffling of genes gave rise to the potato

Knowing potatoes’ origin story could help future-proof the crucial crop against climate threats.

Several researchers who have been critical of Colossal Biosciences’ plans to revive extinct animals say they have been targeted by online articles trying to discredit them

A reanalysis of satellite data shows that a 2017 Texas-to-Missouri lightning megaflash stretched 829 kilometers and lasted 7.39 seconds.

Geologists unpack why the magnitude 8.8 temblor — the sixth largest ever recorded — fomented waves that reached Japan and Hawaii but caused little damage.

Marine biologist Helen Scales's latest book, Ocean Art: From the shore to the deep, celebrates humans' enduring obsession with creatures that live beneath the waves

A fantastic alien adventure can be found on our very own planet by studying the microbial life in Earth's crust, according to Karen G. Lloyd's new book Intraterrestrials

Creatures that lurk more than 9000 metres deep in the Pacific Ocean get their nutrients from a surprising source

A giant stick insect species found in Australia’s Wet Tropics named Acrophylla alta can reach 40 centimetres in length and weigh 44 grams

A leftover from microbes’ meals is linked to early heart disease in people. In mice, it contributed to plaque buildup in the arteries.

Quantum computers in space could be useful for communications networks or for testing fundamental physics.

Research based on game theory suggests if we program AI agents with a sense of guilt, they could behave more cooperatively, much like humans do.

An infinity symbol–shaped galaxy hosts an active supermassive black hole. The growing giant may have come from the aftermath of a galactic smashup.

A fish thought to be evolution’s time capsule just surprised scientists. A detailed dissection of the coelacanth — a 400-million-year-old species often called a “living fossil” — revealed that key muscles believed to be part of early vertebrate evolution were actually misidentified ligaments. This means foundational assumptions about how vertebrates, including humans, evolved to eat and breathe may need to be rewritten. The discovery corrects decades of anatomical errors, reshapes the story of skull evolution, and brings unexpected insights into our own distant origins.
