Researchers report that reef-dwelling hogfish have light-sensitive cells embedded in their skin, allowing the animals to sense brightness and adjust their colour without relying solely on eyes. The study, published in Nature, shows this skin-based photoreception can continue to influence colour change even after death. Hogfish live in Atlantic reefs and can shift hues in milliseconds. Those rapid changes aid camouflage, social signalling and may help with temperature regulation and attracting mates.

During the 2020 lockdown, researchers at the University of East Anglia studied 463 infants aged about eight months to three years to examine nap habits and learning. They tested vocabulary and other cognitive measures and tracked how often and how long children slept. The study found that some children consolidated information during sleep and therefore napped less often, while others who had smaller vocabularies napped more frequently and for longer periods.

A recent YouGov–Cambridge Globalism Project survey finds that voters in Western democracies are more divided by identity and partisan loyalty than by specific policy positions. Researchers describe strong "affective polarization": people feel intense dislike for opposing groups even when those groups often share similar views on key debates such as sexism, racism, and economic policy. The findings challenge the idea that culture wars are mainly about conflicting opinions; instead, much conflict appears driven by who people see as "us" versus "them."

Apple has filed a patent application that describes using motion sensing to detect lip and head movements so Siri could recognize commands without relying only on a microphone. The filing, titled "Keyword Detection Using Motion Sensing," explains how analyzing mouth shapes and subtle head motions might identify common phrases, which could help the assistant work better in noisy environments or avoid false activations from background speech.
