High-Performance Genetically-Targetable Optical Neural Silencing byLight-Driven Proton Pumps
viaNeuroengineers Silence Brain Cells with Multiple Colors of Light.
Newswise — Neuroscientists at MIT have developed a powerful new class of tools to reversibly shut down brain activity using different colors of light. When targeted to specific neurons, these tools could potentially lead to new treatments for the abnormal brain activity associated with disorders such as chronic pain, epilepsy, brain injury, and Parkinson’s disease.

Cells Respond to Laser Light (photonics.com | Sep 2009 | News and Features).
A hybrid protein has been created that causes mouse cells to move in response to laser light. Such cells can be trained to follow a light beam or stop on command.

Newswise — One of the biggest challenges in scientists’ quest to develop new and better treatments for cancer is gaining a better understanding of how and why cancer spreads. Recent breakthroughs have uncovered how different cellular proteins are turned ‘on’ or ‘off’ at the molecular level, but much remains to be understood about how protein signaling influences cell behavior.

Researchers at IBM have devised a simple and efficient way to switch light absorption and emission of carbon nanotubes by applying a weak electric field. Controlling the optical properties of nanotubes in this way will be crucial for future applications in nano-optoelectronics and photonics.

The human body literally glimmers. The intensity of the light emitted by the body is 1000 times lower than the sensitivity of our naked eyes. Ultraweak photon emission is known as the energy released as light through the changes in energy metabolism. We successfully imaged the diurnal change of this ultraweak photon emission with an improved highly sensitive imaging system using cryogenic charge-coupled device (CCD) camera. We found that the human body directly and rhythmically emits light. The diurnal changes in photon emission might be linked to changes in energy metabolism.
