Visceral fat delivers signal to the brain that hurts cognition

Excessive weight around our middle gives our brain’s resident immune cells heavy exposure to a signal that turns them against us, setting in motion a crescendo of inflammation that damages cognition, scientists say. It’s known this visceral adiposity, characterized by an apple-shaped physique, is considered particularly bad for our bodies and brains. But Medical College […]

Men can smell when a woman is sexually aroused: study

Kent research suggests that men can distinguish between the scents of sexually aroused and non-aroused women. The detection of sexual arousal through smell may function as an additional channel in the communication of sexual interest and provide further verification of human sexual interest. This research by Dr. Arnaud Wisman, a Psychologist at Kent, expands on […]

How our brains create breathing rhythm is unique to every breath

Breathing propels everything we do—so its rhythm must be carefully organized by our brain cells, right? Wrong. Every breath we take arises from a disorderly group of neurons—each like a soloist belting out its song before uniting as a chorus to harmonize on a brand-new melody. Or, in this case, a fresh breath. That’s the […]

Artificial sweeteners combined with carbs may be more harmful than those sweeteners alone

The influence of artificial sweeteners on the brain and ultimately metabolism has been hotly debated in recent years. Some studies have found adverse effects on blood sugar and insulin levels, while others have not. In a study publishing March 3 in the journal Cell Metabolism, researchers say the discrepancies in these studies may be due […]

Scientists shed new light on neural processes behind our desire for revenge

New insight on the neural processes that drive a desire for revenge during conflict between groups has been published today in the open-access journal eLife. The study suggests that the ‘love hormone’ oxytocin is increased during conflict between groups and influences the medial prefrontal cortex, the section of the brain associated with our decision-making activity. […]

Influenza: Combating bacterial superinfection with the help of the microbiota

Researchers from the Lille Centre for Infection and Immunity (CNRS/INSERM/Institut Pasteur de Lille/University of Lille/CHU Lille), INRAE and from Brazilian (Belo Horizonte), Scottish (Glasgow) and Danish (Copenhagen) laboratories have shown for the first time in mice that perturbation of the gut microbiota caused by the influenza virus favours secondary bacterial superinfection. Published in Cell Reports […]

Mother nose best: Child body odor provides olfactory clues to developmental stages

It’s no secret that babies generally smell pleasant to their mothers—and teenagers not so much. A team of researchers investigating how body odors affect the mother-child relationship found that a mom’s olfactory sense may be capable of detecting her child’s developmental stage. The research was published in the journal Frontiers in Psychology. The ability of […]
