Scientists have dusted off the mechanics behind a 100-year-old valve and are reimagining it for use in current and future technology. The device, originally known as a “valvular conduit,” was invented ...

For integrated photonics to take off, light signals zooming around optical chips must be successfully isolated from one another. Scientists at Stanford University have now designed a miniature one-way ...

Heart valves allow blood to flow one way and prevent it from flowing in the wrong direction. The tricuspid valve controls blood flow between the right atrium and right ventricle. The bicuspid or ...
