Engineers light the way to nerve-operated prosthetics of the future

Biomedical and electrical engineers at UNSW Sydney have developed a new way to measure neural activity using light—rather than electricity—which could lead to a complete reimagining of medical technologies like nerve-operated ...

Nerve stimulation promotes resolution of inflammation

The nervous system is known to communicate with the immune system and regulate inflammation in the body. Researchers at Karolinska Institutet in Sweden now show how electrical activation of a specific nerve can promote healing ...

Novel sensors enable precise measurement of dopamine

Dopamine is an important signaling molecule for nerve cells. Its concentration could not be precisely determined with both high spatial or temporal resolution until now. A new method has now made this possible: A research ...

How it works: The protein that stimulates muscle growth

In the gym, you are not just pumping iron, you are oxygenating muscle cells which keeps those muscles healthy, strong and growing—a process called hypertrophy, or an increase in muscle mass due to an increase in muscle ...
