'You are getting very sleepy': When hypnotism came to America
In the early 19th century, American factory workers often labored for 12-hour shifts, six days a week, and weaver Cynthia Gleason was having trouble sleeping.

Parents cherish developmental milestones, from a newborn's grip of an offered finger; to an infant's holding her head up the first time; to rolling over, creeping, and crawling; then to standing, cruising, and finally walking. Even kicking during a diaper change or yowling requires muscle strength and coordination. But a boy with X-linked myotubular myopathy (MTM) is so weak that even breathing is a huge struggle. If a baby survives the initial hospital stay, care at home becomes a full-time job and is only supportive, delaying the inevitable. That grim picture may be changing.

Identifying a subgroup of heart failure patients could lead to improved care
