How light triggers brain activity

Optogenetics uses light to control brain processes. It is based on light-controlled proteins such as channelrhodopsin-2, an ion channel that opens when it's exposed to light, thus activating cellular processes. In collaboration ...

Revolutionizing the revolutionary technology of optogenetics

The revolution that optogenetics technology has brought to biology—neuroscience in particular—could be transformed all over again if a new project getting underway at Brown University and Central Michigan University (CMU) ...

Hunting the ion channel

The electrical impulse that powers the workings of the brain and the heart begins with charged particles passing through cellular structures known as ion channels. Using the same technique used to decode the structure of ...

Breakthrough could prevent hip implant replacement

Hip implants rely on the normal functioning of bone cells to achieve fixation of the implant with the bone. However, small metal particles released from hip implants, due to friction between the moving surfaces, have been ...

Switching brain cells with less light

Networked nerve cells are the control center of organisms. In a nematode, 300 nerve cells are sufficient to initiate complex behavior. To understand the properties of the networks, re-searchers switch cells on and off with ...

Explainer: What is proton therapy?

When you stand in the 27km-long Large Hadron Collider tunnel deep under Switzerland and France it looks as if the chain of blue magnets simply stretches off to infinity. So when people talk about putting particle accelerators ...

Study finds linchpin of skin response to UVA light

Last year, a team of researchers at Brown University discovered that certain skin cells use a light-sensitive receptor found outside of the eye to sense ultraviolet light and quickly begin pumping out melanin to protect against ...
