Childhood food, skin allergies on the rise

Food and skin allergies are becoming more common in American children, according to a new report from the Centers for Disease Control and Prevention. Both have been steadily increasing for more than a decade.

Food allergy prevalence increased from 3.4% to 5.1% between 1997 and 2011, while skin allergy prevalence more than doubled in the same time period. That means 1 in every 20 children will develop a food allergy and 1 in every 8 children will have a skin allergy.  According to the CDC, respiratory allergies are still the most common for children younger than 18.

The new report, which looked at data from the National Health Interview Survey, found that skin allergies decreased with age, while respiratory allergies increased as children got older.

Kids’ brains can predict math tutor benefit

Kids don't all learn at the same pace, or in the same way. Extra tutoring doesn't always help either, but for some it helps a lot. Why?

Researchers, publishing this week in the journal Proceedings of the National Academy of Sciences, believe the answer is in the brain. By looking at the structures and wiring of children's brains, they've developed a method of predicting who will benefit most from tutoring.

This doesn't mean, however, that you will be seeing brain scans in every school.

"What we’ve done is much more modest, in terms of trying to understand what are the systems that underlie individual differences in response to math tutoring," said Vinod Menon, professor at Stanford University School of Medicine and senior author of the study.
