European orbiter detects fresh hints of volcanic activity on Mars

New evidence from gas seeping above volcanic rifts suggests Mars is not geologically dead deep inside, but merely sleeping. Fresh fissures along the Alba Mons region hint at active spots under the surface, where gases from ...

Chatbots with personality? How AI describes itself and judges us

Texts generated by large language models, or AI-powered chatbots, exhibit characteristic "personality" traits. Such chatbots can also identify individual personality traits in texts. However, humans are more reliable at distinguishing ...

Gold mining introduces an overlooked threat to wild caimans

Mercury pollution from artisanal gold mining in tropical regions is finding its way into wildlife. A team from the University of Vienna and the Veterinary University of Vienna shows that mercury exposure impairs the glucocorticoid ...

Foot-stiffening socks could make walking less tiring

Human feet are much stiffer than those of other primates, which means they limit midfoot bending during walking. The evolutionary reasons for this are not entirely clear. One idea is that the features that stiffen the foot ...

NOAA, NASA release measurements of 2026 ozone hole

Atypical weather conditions caused the Antarctic ozone hole to grow to an unusually large size in 2026, NOAA and NASA scientists reported today, though they said the protective ozone layer is still on track to recover by ...

Mitigating the ecological consequences of light pollution

Light pollution is one of the fastest-growing and least-regulated environmental changes worldwide. It disrupts biological processes at all levels—from genes to entire ecosystems—and contributes significantly to global biodiversity ...

Unveiling the science behind a beautiful singing voice

Expert listeners can often form an immediate impression of a singer's performance. But what exactly in the voice drives that judgment? In classical vocal competitions, performers are rated on an overall score. However, the ...
