Global Stress and Inflammation: A Cycle of Societal Dysfunction

Researchers propose a groundbreaking hypothesis, linking chronic stress and inflammation to societal and cognitive dysfunction on a global scale. They suggest that the brain's 'central inflammation map' could be impaired by chronic inflammation, affecting individual and collective decision-making, and behaviors.

Hallucinations Enhance Social Number Misjudgment

Hallucinations, particularly presence hallucinations often experienced by individuals with Parkinson's disease, can lead to an increased overestimation of social numbers, such as the number of people in a room. This phenomenon does not extend to inanimate objects like boxes, underscoring the social nature of this overcounting.

Happiness Takes Practice

Happiness can indeed be learned through courses like their 'Science of Happiness', which educates students on evidence-informed habits for well-being. However, a follow-up study indicates that the initial boost in well-being requires sustained effort and continued practice of these habits, such as gratitude and meditation, to maintain long-term benefits.

Revolutionizing Softness Perception in Robotics

Researchers developed SORI, a groundbreaking Softness Rendering Interface that can accurately simulate the perception of softness, addressing a long-standing challenge in robotics. By distinguishing between cutaneous and kinesthetic cues, SORI can replicate the softness of various materials, from marshmallows to beating hearts, offering vast applications in medicine, deep-sea exploration, and robot-assisted agriculture. This innovation not only advances the field of robotics but also provides a novel way to digitally transfer the sensation of touch, bridging a gap in human-robot interaction.

Bilingualism: Native Language Eases Brain’s Effort

A novel study unveiled how the brain processes native and foreign languages differently in polyglots. By examining brain activity in individuals proficient in five or more languages, the study found that the brain's language network responds more intensely to non-native languages, except for the native language, which shows significantly less activation.
