For how we live.
An independent 2026 meta-analysis of AAV micro-dystrophin trials found small, mostly uncontrolled functional benefits — largest in the youngest boys — set against serious harms including rare deaths.
Around 60–70% of infants carry Clostridioides difficile without illness. A Science study finds its toxins remodel the newborn gut in mice — but the direct human evidence is still limited to cells and biopsies.
An injection at birth prevents a rare but often catastrophic bleeding disorder. Pooled surveillance data put late-onset bleeding at a median of 35 per 100,000 unprotected infants — and near zero after the shot.
Back sleeping, a firm flat surface, and room-sharing without bed-sharing are the core of the American Academy of Pediatrics' safe-sleep guidance. Roughly 3,500 US infants still die in sleep each year.
The blood test known as NIPT is a strong screen for Down syndrome but not a diagnosis. In a general-risk population a positive result was correct about 81% of the time — and much less often for rarer conditions.
A few drops of blood taken in the first days of life are checked for dozens of rare but treatable disorders. The US panel has grown from 29 conditions to 35, and states adopt each one at very different speeds.
