Scientists develop new device to detect brain tumors using urine

Researchers at Nagoya University in Japan have used a new device to identify a key membrane protein in urine that indicates whether the patient has a brain tumor. This protein could be used to detect brain cancer, avoiding ...

A simplified method for calibrating optical tweezers

Measurements of biomechanical properties inside living cells require minimally-invasive methods. Optical tweezers are particularly attractive as a tool. They use the momentum of light to trap and manipulate micro- or nanoscale ...
