Half of all stillbirths result from pregnancy disorders and conditions that affect the placenta, a new study found. Risk factors known at the start of pregnancy accounted for only a small proportion of the overall risk of stillbirth.
Scientists report that a single dose of an experimental gene therapy boosted production of a missing blood-clotting factor in people with hemophilia. The therapy could provide a long-term solution for preventing dangerous bleeding.

Recurrent wheezing in children at risk for developing asthma can be controlled using far less medication by giving higher doses of an inhaled corticosteroid only as needed instead of lower doses every day, a study found.
Preemies born as early as the 23rd week of pregnancy are more likely to survive and have less brain injury if their mothers receive prenatal steroids, according to a new study.

A new study found that wood-burning cooking stoves with chimneys lowered exposure to wood smoke from open cooking fires and reduced the rate of severe pneumonia by 30% in young children.
Scientists have developed a noninvasive technique that uses light to wipe out cancerous cells in mice without harming surrounding tissue. The novel method might eventually be used to treat tumors in humans.
Researchers have found what appear to be 2 key components of the long-sought-after mechanotransduction channel in the inner ear—the place where sound waves are transformed into the electrical signals that the brain recognizes as sound.
