Writing in the journalĀ Proceedings of the National Academy of Sciences, the researchers said the results helped explain how poor sleep damaged health. Heart disease, diabetes, obesity and poor brain function have all been linked to substandard…

Successful Human Tests for First Wirelessly Controlled Drug-Delivery Chip

Successful Human Tests for First Wirelessly Controlled Drug-Delivery Chip

About 15 years ago, MIT professors Robert Langer and Michael Cima had the idea to develop a programmable, wirelessly controlled microchip that would deliver drugs after implantation in a patient’s body. This week, the MIT researchers and scientists from MicroCHIPS Inc. reported that they have successfully used such a chip to administer daily doses of an osteoporosis drug normally given by injection. The results, published in the Feb. 16 online edition of Science Translational Medicine, represent the first successful test…
