Les SMS ont-ils contaminé votre cerveau ?
Slate France: Selon ABI Research, un cabinet d’études spécialisé dans les nouvelles technologies, ils’enverra plus de 7 000 milliards de SMS dans le monde au cours de l’année 2011. Etant donné que la population de la Terre aura, d’ici au 31 décembre, passé la barre des 7 milliards d’individus, cela fera une moyenne de 1 000 SMS par personne.

How a Mother’s Love May Counter the Negative Health Effects of Poverty
TIME: Being raised in poverty can have lifelong negative effects on children's health, increasing their risk of chronic disease in adulthood. But new research suggests one factor that may help protect poor kids from later illness: having a nurturing mother. Growing up poor is stressful, and chronic stress is known to impact physical health long term. Research finds that poor kids are more likely to develop metabolic syndrome — a collection of risk factors that may lead to Type 2 diabetes, cardiovascular disease and stroke — compared with their wealthier peers, for example.

If you try to do it, you cause “crowding out.” People focus on everything you’ve included and exclude everything else. What’s left out of the contract tends to drop out of their motivation as well. You are taking away from their judgment and goodwill and teaching them to be like rats in a maze.

Winners of MacArthur Foundation award include 10 people who focus on science
The Washington Post: Nine scientists and a science radio host were among the 22 people who received $500,000 MacArthur “genius” grants last week.

Let Students Sleep
New York Times: Efforts to improve educational outcomes through extending the school day may have unintended and counterproductive consequences if longer days are implemented by moving the school bell earlier or by pushing more homework later into the night. Young children are biologically primed for "early to bed and early to rise," but as children pass through middle school and into high school, biological processes keep them up later.
