Sourire est bon pour le coeur (Smiling is good for the heart)
Slate: Et si un sourire, même forcé, permettait de réduire son stress? Les docteurs Tara Kraft et Sarah Pressman de l'université du Kansas ont décidé de se pencher sur la question. Dans Psychological Science, elles expliquent leur étude. Les scientifiques ont recruté 169 étudiants sans leur expliquer le but réel de l’expérience, afin de ne pas fausser les résultats. En premier lieu, les chercheuses ont demandé aux personnes de mettre des baguettes dans la bouche afin de simuler une expression faciale précise.

Why Do Older Adults Display More Positive Emotion? It Might Have to Do with What They’re Looking At
Research has shown that older adults display more positive emotions and are quicker to regulate out of negative emotional states than younger adults.

Disharmony in the Land of Nod
The Huffington Post: The most compelling personal memoirs -- Tobias Wolff's This Boy's Life, Mary Karr's The Liars' Club, and others -- are not happy stories. They are recollections of childhood adversity, and rarely are they triumphant survivors' tales. The most honest of these remembrances are accounts of the lingering scars and damage done. And damage is done. Scientists have thoroughly documented the pernicious effects of traumatic childhood events, right down to the cellular level. The young brain is highly vulnerable to all sorts of stress, and study after study has shown that childhood troubles can skew the development of key neural networks involved in emotional stability.

The yuck factor: The surprising power of disgust
New Scientist: DAVID PIZARRO can change the way you think, and all he needs is a small vial of liquid. You simply have to smell it. The psychologist spent many weeks tracking down the perfect aroma. It had to be just right. "Not too powerful," he explains. "And it had to smell of real farts." It's no joke. Pizarro needed a suitable fart spray for an experiment to investigate whether a whiff of something disgusting can influence people's judgements. His experiment, together with a growing body of research, has revealed the profound power of disgust, showing that this emotion is a much more potent trigger for our behaviour and choices than we ever thought.

Dating in a Digital World
Scientific American: Romantic relationships can begin anywhere. When Cupid's arrow strikes, you might be at church or at school, playing chess or softball, flirting with a friend of a friend at a party or minding your own business on the train. Sometimes, however, Cupid goes on vacation, or takes a long nap, or kicks back for a marathon of Lifetime original movies. Instead of waiting for the capricious arrow slinger to get back to work, people are increasingly joining online-dating sites to assert some control over their romantic lives.
