Scientists have been able to observe sperm cells since the invention of the optical microscope. But capturing their unique swimming motion in 3D has been surprisingly challenging — and that information is valuable because it could help explain the key physical attributes of healthy and defective sperm. Now, a microscope developed by researchers at the…

Researchers from UCLA and the University of Connecticut have designed a new biofriendly energy storage system called a biological supercapacitor, which operates using charged particles, or ions, from fluids in the human body. The device is harmless to the body’s biological systems, and it could lead to longer-lasting cardiac pacemakers and other implantable medical devices.…

UCLA researchers working with a team at Verily Life Sciences have designed a mobile microscope that can detect and monitor fluorescent biomarkers inside the skin with a high level of sensitivity, an important tool in tracking various biochemical reactions for medical diagnostics and therapy. This new system weighs less than a one-tenth of a pound,…
