Egypt's deserts were once home to a diverse shark community
During the Late Cretaceous period, parts of Egypt were covered in water. A new study, published in the journal Cretaceous Research, describes new evidence that this tropical sea was home to a diverse community of sharks. The study adds five new species to the region's history, found in what the authors refer to as a "shark graveyard."

How people treat you may shape your reputation and stabilize cooperation
When one person helps, or refuses to help, another in public, this may change not only the provider's reputation but also the recipient's. A theoretical study led by Kobe University offers a simple explanation for how cooperation in large communities becomes stable and provides insights into phenomena like the bystander effect.

Nanoscale hairs may help gecko skin trap moisture and slow evaporation
In a dry shrubland, a gecko sprints toward shelter. Its greatest danger is not a predator, although hawks circle overhead and sand cats wait in ambush. Rather, its most pressing concern is dehydration. Its skin is paper-thin; water can evaporate from its body into the dry air more quickly than it can replenish it. Fortunately, evolution has given it an adaptation: thin, nanoscopic hairs, called setulae, that cover its body and trap moisture.

A tiny drop of water is all that's needed to find threatened frogs
New James Cook University research has used highly sensitive environmental DNA (e-DNA) techniques to find two species of threatened frogs in places they've never been seen before—and find another still struggling to recover from past disease outbreaks. The research is published in the journal Conservation Science and Practice.

Chatbots are making our writing more similar but losing the identity and personality behind it
Large language models (LLMs) are making writing styles more similar without changing the overall meaning, according to an analysis of more than 880,000 texts across different writing types published in Nature Human Behaviour. The findings indicate that using LLMs could make it more difficult to identify important clues about aspects of a person's identity, personality and mental health from their language.

Left‑handed people tend to be left‑leaning voters
Political preferences are generally explained by income, age and level of education. However, our research suggests that a far more unexpected trait may also have a hand in how we vote. A survey carried out in 18 western countries has shown that left-handed people tend to identify more strongly with the political left. This finding appears to be more related to identity than biology.
