Risk assessment Researchers from Caltech and the Keck School of Medicine at USC have created a portable laser-based headset that can estimate stroke risk. Caltech postdoctoral scholar Simon Mahler is ...

Blood flow restriction training—once a niche rehabilitation method used primarily by physical therapists—has quietly transformed into one of fitness’s most intriguing innovations. This technique uses ...

A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation ...

Researchers have developed a laser-based device that can measure blood flow noninvasively and differentiate stroke risk based on current physiological conditions. When physicians want to know more ...
