Narcissism predicted lower anxiety and psychopathy predicted lower heart-rate reactivity. Credit: Yan Krukau Better immunity to stress is a superpower most of us would like to possess. Surprisingly, people with certain dark personality traits do have better protection against stress than most people. A recent study has found that people with the Dark Triad of personality traits—narcissism, psychopathy and Machiavellianism—respond to stress differently.

A simplified diagram illustrating "cannibalism order." As human-to-human consumption is repeated (A → B → C), the risk of transmitting infectious diseases increases, making cannibalism progressively less advantageous over time, according to the study's model.

In fact, Western Europe's average summer temperature has climbed by roughly 2.3°C since 1980, about triple the 0.8°C global rise. This discrepancy, where observed warming far outpaces what climate models initially predicted, has puzzled scientists.

What if there's a basic item you keep at home that could represent a brand-new field of brain defense? Sorghum is a widely available cereal crop. Scientists recently conducted an experiment to test its effects and found something striking.

A schematic showing how a skin wound disrupts the epithelium, creating a natural electric field that guides immune cells toward the injury site during wound healing. Credit: generated using AI tools for illustrative purposes When skin is wounded, it doesn't just send out chemical distress signals; it also generates a subtle electrical field. This "electric beacon" forms as the usual voltage across the tissue collapses, creating a guiding current around the injury.

An illustrated five-panel vignette showing a child's decision-making scenario used to study sunk-cost reasoning. A girl first sees two identical flowers in different locations—one on an easy path and one on a difficult hill. She picks the easy-to-reach flower, then climbs the harder path to collect the second flower. In the final panel, she holds two identical flowers and must choose which one to keep, highlighting the question of whether past effort influences her decision.

Artist's concept of the TOI-1710 system showing a retrograde warm Neptune on a tilted orbit, a closer giant planet, and a distant M-dwarf companion. The illustration highlights how these companions may interact to flip Neptune's orbit.
