Wielding a laser beam deep inside the body

Minimally invasive surgeries in which surgeons gain access to internal tissues through natural orifices or small external excisions are common practice in medicine. They are performed for problems as diverse as delivering ...

For neural research, wireless chip shines light on the brain

Researchers have developed a chip that is powered wirelessly and can be surgically implanted to read neural signals and stimulate the brain with both light and electrical current. The technology has been demonstrated successfully ...

Implantable device can monitor and treat heart disease

Pacemakers and other implantable cardiac devices used to monitor and treat arrhythmias and other heart problems have generally had one of two drawbacks—they are made with rigid materials that can't move to accommodate a ...

An acoustically actuated microscopic device

Researchers at EPFL have developed remote-controlled, mechanical microdevices that, when inserted into human tissue, can manipulate the fluid that surrounds them, collect cells or release drugs. This breakthrough offers numerous ...

Microscopic robots 'walk' thanks to laser tech

A Cornell University-led collaboration has created the first microscopic robots that incorporate semiconductor components, allowing them to be controlled—and made to walk—with standard electronic signals.

Super-strong surgical tape detaches on demand

Last year, MIT engineers developed a double-sided adhesive that could quickly and firmly stick to wet surfaces such as biological tissues. They showed that the tape could be used to seal up rips and tears in lungs and intestines ...
