Psychology Today: Stop doing this one thing that makes your brain unhappy

“The really efficient laborer will be found not to crowd his day with work, but will saunter to his task surrounded by a wide halo of ease and leisure.”—Henry David Thoreau.

Chicago Tribune: How your brain chooses the people you desire

Science says your attraction meter is similar to a video game: If you’re a woman, you’ll score two points for having a lower back curve (you look fertile), gain a point for being intelligent, but lose one for being too smart.

News-Medical: Neuroscientists show how the brain responds to texture

Our hands and fingertips are amazingly sensitive to texture. We can easily distinguish coarse sandpaper from smooth glass, but we also pick up more subtle differences across a wide range of textures, like the slick sheen of silk or the soft give of cotton. Information about texture is transmitted from sensors in the skin and […]

Medical News Today: Alcohol use disorder: A step toward better treatment?

Horizon: Pushing the bounds of vision could reveal hidden worlds

Human senses have already been highly tuned by millions of years of evolution. Our eyes, for example, sit on the front of our faces, allowing us to see in three dimensions, while the cells of our retina are sensitive to different wavelengths of light, giving us colour vision. But our senses have limits. A speeding […]

Psychology Today: Exercise-linked irisin may protect against neurodegeneration

A new study by an international team of researchers reaffirms the potential neuroprotective power of exercise-induced irisin. Since the hormone irisin was first discovered less than a decade ago, there’s been some debate about whether or not irisin is, in fact, the powerful exercise-induced messenger that the pioneering researchers at Harvard Medical School led by […]
