It’s been known for awhile that reading to a young child is associated with good outcomes, including language development and school success. But what remains unknown is the mechanism for these outcomes. A new study, published in the journal Pediatrics, examines the unexpectedly complex interactions that happen in the brain when you put a small child on your lap and open a picture book.

Ben Allen/WITF. Cris and Valerie Fiore hold one of their favorite pictures of their sons Anthony (with the dark hair) and Nick. Anthony died from a heroin overdose in May 2014 at the age of 24.

Federal law requires insurance firms to cover treatment for addiction as they do treatment for other diseases. But because addiction treatment is so different from treatment for other medical issues, it’s hard to figure out exactly what equal treatment looks like, and some families say that drug users aren’t getting the care they need.

The Paleo diet is based on the belief that we should eat foods that our ancestors ate. Typically this means that Paleo diet followers stick to diet high in meats and vegetables, and steer clear of carbohydrates. Newly published research is arguing this notion, and hypothesizes that the human brain needed glucose provided by carbohydrates to evolve.

Dozens of games and apps claim to improve your memory or make you smarter or reduce stress. But do they really? In October 2014, 75 scientists signed a letter to the brain training industry, criticizing companies for exaggerating claims and preying on the anxieties of customers. Now game developers say the next step is clinically valid poof of cognitive gains, and one developer (also a neuroscientist) is looking for the best proof he can get — FDA approval — and he’ll start with his game NeuroRacer which already has results published in the journal Nature.

Mary McLain/NPR

You are probably at least a little bit racist and sexist and homophobic. Most of us are. And before you get offended, try taking one of the popular Implicit Association Tests. They measure people’s unconscious prejudice. These tests find that most people trust men or women, white people over minorities, and straight people over queer people.

So, what are we to do? Scientists are working on ways to train our brains away from deeply held prejudices — including hacking your subconscious while you sleep. Yes, it sounds like a scam, but the results, published in the journal Science, show that it’s possible.

Photograph by Jack Wilgus of a daguerreotype of Phineas Gage in the collection of Jack and Beverly Wilgus.

Thanks to painstaking historical analysis of primary sources (by Malcolm Macmillan and Matthew Lena) – much of it published between 2000 and 2010 – and the discovery during the same time period of new photographic evidence of post-accident Gage (see image, right), it is now believed that Gage made a remarkable recovery from his terrible injuries. He ultimately emigrated to Chile where he worked as a horse-coach driver, controlling six horses at once and dealing politely with non-English speaking passengers. The latest simulations of his injury help explain his rehabilitation – it’s thought the iron rod passed through his left frontal lobe only, leaving his right lobe fully intact.
