Surgeons reroute nerves to restore hand, arm movement to quadriplegic patients

October 15, 2015

A nerve transfer bypasses the zone of a spinal cord injury (C7). Functional nerves (green) that are under volitional control are rerouted (yellow) to nerves (red) that come off below the spinal cord injury. (credit: Washington University in St. Louis)

Smart robot accelerates cancer treatment research by finding optimal treatment combinations

September 23, 2015

Iterative search for anti-cancer drug combinations. The procedure starts by generating an initial generation (population) of drug combinations randomly or guided by biological prior knowledge and assumptions. In each iteration the aim is to propose a new generation of drug combinations based on the results obtained so far. The procedure iterates through a number of generations until a stop criterion for a predefined fitness function is satisfied. (credit: M. Kashif et al./Scientific Reports)

3D-printed silicone guide with chemical cues helps regenerate complex nerves after injury

Controlling brain cells with ultrasound

Sonogenetics may be able to selectively activate brain, heart, muscle, and other cells using ultrasonic waves, similar to optogenetics
September 15, 2015

For the first time, sound waves are used to control brain cells. Salk scientists developed the new technique, dubbed sonogenetics, to selectively and noninvasively turn on groups of neurons in worms that could be a boon to science and medicine. (credit: Salk Institute)
