When bottom trawls are dragged across the seafloor, they stir up sediments. This not only releases previously stored organic carbon, but also intensifies the oxidation of pyrite, a mineral present in marine sediments, leading to additional emissions of carbon…

Female bonobos team up to suppress male aggression against them -- the first evidence of animals deploying this strategy. In 85% of observed coalitions, females collectively targeted males, forcing them into submission and shaping the group's dominance…

A 113-million-year-old hell ant that once lived in northeastern Brazil is now the oldest ant specimen known to science, finds a new report. The hell ant, which was preserved in limestone, is a member of Haidomyrmecinae -- an extinct subfamily that only lived…

Scientists have discovered how chemokines and G protein-coupled receptors selectively bind each other to control how cells move.

Researchers discovered tiny features on sculpins' fins which may enable them to cling firmly in harsh underwater environments.

Bite marks found on a skeleton discovered in a Roman cemetery in York have revealed the first archaeological evidence of gladiatorial combat between a human and a lion.

Piperacillin, an antibiotic in the same class as penicillin, effectively cured mice of Lyme disease at 100-times less than the effective dose of doxycycline, the current gold standard treatment. At such a low dose, piperacillin also had the added benefit of…

In the soils of Earth's wetlands, microbes are in a tug-of-war to produce and consume the powerful greenhouse gas methane. But if the Earth gets too hot, it could tip the scale in favor of the methane producers, according to a new study. Scientists made the…

Paper shares innovative natural capital accounting approach to valuing the benefits of ecosystems in Colombia's Upper Sin Basin to key economic sectors.

A team of biomedical researchers trained a machine learning algorithm to identify more than two dozen viable treatments for diseases caused by zoonotic pathogens that can jump from animal hosts to infect humans. Scientists used Rhodium software to study…

The link between proximity to greenspace -- including trees and parks-- and healthy birth outcomes is well established. Now new data adds to our understanding of these health benefits, accounting for other factors that may influence this link, such as…

An international team has identified a potential microbial culprit behind the alarming rise in early-onset colorectal cancer: a bacterial toxin called colibactin. Scientists report that exposure to colibactin in early childhood imprints a distinct genetic…

A small study found that fatty buildup in the blood vessels of the neck (carotid arteries) may contain 50 times or more micronanoplastics -- minuscule bits of plastic -- compared to arteries free of plaque buildup.

Body appreciation differs between Middle-Eastern and Western societies, a new international study can reveal, highlighting how cultural and family influences shape body image and eating behaviors in young women. The study surveyed over 850 women aged 18-25 in…

Multiple climate 'tipping points' are likely to be triggered if global policies stay on their current course, new research shows.

A new catalyst structure offers a potential pathway toward more cost-effective hydrogen production via water electrolysis. The material centers on mesoporous single-crystalline Co3O4 doped with atomically dispersed iridium (Ir), designed for the acidic oxygen…

Over the past two decades, satellite-based planetary observations have recorded rapid mass loss of Patagonian glaciers, contributing approximately 0.07 mm per year to global sea-level rise. A study links this mass loss to a poleward shift of subtropical…

If you haven't heard of a tardigrade before, prepare to be wowed. These clumsy, eight-legged creatures, nicknamed water bears, are about half a millimeter long and can survive practically anything: freezing temperatures, near starvation, high pressure,…

Ancient DNA analysis challenges our understanding of the ancient Phoenician-Punic civilization. An international team of researchers analyzing genome-wide data from 210 ancient individuals has found that Levantine Phoenician towns contributed little…

New research shows that Lesser Goldfinches, a small songbird traditionally found in Southwest USA, are expanding their range northward through the Pacific Northwest at an unprecedented rate, providing insights into how species adapt to environmental change.
