Specialized cells called pericytes are crucial to protecting the central nervous system, two new studies demonstrate.

Pesticide in womb may promote obesity, study finds
One-quarter of babies born to women who had relatively high concentrations of a DDT-breakdown product in their blood grew unusually fast for at least the first year of life. Not only is this prevalence of accelerated growth unusually high, but it’s also a worrisome trend since such rapid growth during early infancy has — in other studies — put children on track to become obese.

Getting to the bottom of diabetes and kidney disease
Renal cells called podocytes may need insulin to maintain tissues’ blood-filtration role, a study in mice finds.
