Improving the care delivered to children with special health care needs

Health care delivered close to home is vitally important, especially when the patient is a child. But how do community pediatric practices adapt to offer the best care when faced with a child who has complex and often, multiple health needs? Reporting in this month's issue of Pediatrics, Dartmouth researchers outline a process designed to help any practice become a state of the art "medical home" for such children.

Office of Naval Research harnessing human brain power to control the maneuvers of UUVs

Even the least graceful among us has motor control the most high-tech unmanned undersea vehicle would envy, thanks to a region of the brain that allows our bodies to carry out complex maneuvers. The Office of Naval Research, which traditionally relies on the power of the human mind to achieve breakthroughs in science and technology, now also is harnessing the working principle of the brain to control the maneuvers of UUVs.
