Bad sleep ‘dramatically’ alters body

Bad sleep ‘dramatically’ alters body

A run of poor sleep can have a dramatic effect on the internal workings of the human body, say UK researchers.

The activity of hundreds of genes was altered when people’s sleep was cut to less than six hours a day for a week.

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 sleep.

What missing hours in bed actually does to alter health, however, is unknown.

So researchers at the University of Surrey analysed the blood of 26 people after they had had plenty of sleep, up to 10 hours each night for a week, and compared the results with samples after a week of fewer than six hours a night.

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 of such a device and could help usher in a new era of telemedicine — delivering health care over a distance, Langer says.

“You could literally have a pharmacy on a chip,” says Langer, the David H. Koch Institute Professor at MIT. “You can do remote control delivery, you can do pulsatile drug delivery, and you can deliver multiple drugs.”
