Everyday financial anxieties and frustration with low-quality work – rather than immigration alone – helped populist politics explode across Europe from the mid-2010s, according to a new book that analyses data from over 75,000 voters.

The study shows that the brain’s representation of social boundaries can rapidly reorganise in response to context. The research team suggests that this neural flexibility underlies the human ability to navigate complex social environments characterised by multiple and interconnected group identities. Understanding these mechanisms is crucial for developing effective strategies to bridge divisions and foster more harmonious intergroup relations.

Researchers found more than 40% of elementary school children who experienced bullying showed trauma symptoms, highlighting a major child mental health concern.

It’s not how many people you know, but how connected you feel. That difference can shape health and behavior.

Centenarians often live to 100+ due to a combination of protective genetic factors, which account for up to 50%, and healthy lifestyles, such as plant-forward diets, regular, natural movement and strong social connections. While these “agers” often possess unique immune system signatures, understanding the metabolic signs of healthy aging is not yet fully understood.

In a new study from Boston University Chobanian & Avedisian School of Medicine, researchers have discovered that centenarians have a distinct blood metabolite pattern that is not just an extension of normal aging. In particular, they show uniquely higher levels of certain primary and secondary bile acids and preserved levels of several steroids, patterns that diverge from the typical age trends seen in non-centenarians and that are linked to lower death risk.
