X-ray snapshots reveal how viral shells change shape as they dry out

When viruses travel through the air in tiny droplets, they can quickly start to dry out. Yet many viruses remain infectious after rehydration—something that is still not fully understood. Now, an international team of researchers has directly observed at the European XFEL how the

Beetle-like borings in 70-million-year-old titanosaur fossils reshape Lo Hueco fossil stor

Traces or perforations caused by living organisms after an animal's death can be found on various dinosaur bone remains. These perforations, known as bioerosion structures, provide information that helps us understand relationships between living organisms in the past, reconstruc

Uranus, Neptune may be magma worlds, not ice giants

Uranus and Neptune remain two of the most mysterious objects in the solar system, primarily because they have been visited only by NASA's Voyager 2 spacecraft in 1986 and 1989, respectively. Their "ice giant" moniker comes from longstanding hypotheses that their interiors are com

The bond between humans and dogs remains remarkably consistent across societies, cross-cul

A new study by an international research team led by Friedrich Schiller University Jena and the Max Planck Institute for Evolutionary Anthropology (Leipzig) has revealed striking similarities in the way humans and dogs interact in very different societies. The research is publish

New workflow transforms nonfunctional protein scaffolds into active enzymes

Enzymes are regarded as the key to sustainable chemistry. Despite major advances in protein design, creating artificial enzymes from scratch has so far remained a grand challenge. A research team at the University of Bayreuth, in collaboration with scientists from the University

Mummified dogs reveal Tiwanaku people buried companions beside homes long before they beca

In the arid landscapes of southern Peru, around 1,100 years ago, someone carefully dug a small pit, laid down a woven mat and placed a young dog within as if sleeping, possibly wrapped in twine. Centuries later, the mummified remains would be one of only two intentionally buried

Nanopore technology identifies proteins molecule by molecule

Proteins are responsible for most functions in the human body. However, their analysis, which is essential for understanding diseases, developing drugs and discovering new biomarkers, remains highly complex. Using a technology called "nanopore detection," a team at the University

Measuring process over product: AI approach assesses learning processes

Artificial intelligence (AI) is profoundly reshaping education worldwide. While AI tools increasingly support students in brainstorming, drafting and problem-solving, assessment practices often remain narrowly focused on final outputs. This raises a critical question: How can edu

How PFAS chain length influences environmental fate and water treatment

Per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," are among the most persistent contaminants found in water systems worldwide. Their strong carbon-fluorine bonds make them highly resistant to degradation, allowing them to remain in the environm

Country diary: This is as wild and remote as Britain gets – a trip to St Kilda | Nigel Bro

Outer Hebrides: It’s nearly 100 years since anyone lived on this hostile archipelago, though their ‘village’ remains – as does an astonishing wealth of wildlife Dawn on a deep-rolling ocean, and I am about to realise a dream. We’re 35 nautical miles west of the Outer Hebrides, on

Women hold just 3% of jobs in tourism's biggest transport sector, global study finds

Women remain vastly underrepresented in tourism transport jobs worldwide, making up just 3% of land passenger transport workers (such as bus and train staff) in countries with available data, according to a University of Surrey-led report.

Tiny ancient fish fossil with preserved brain offers clues to early fish evolution

Over 300 million years ago, a minnow-sized fish died and fell to the bottom of a prehistoric swamp near the village of Trawden, Lancashire, in northwest England. The remains of this tiny fish—known as Trawdenia planti—became fossilized, embedding proof of its existence in a layer
