What Physicists Can Learn from Shark Intestines

ROCKVILLE, MD – In 1920, inventor Nikola Tesla patented a type of pipe that he called a “valvular conduit,” which was built to draw fluid in one direction without any moving parts or added energy, and has applications ranging from soft robotics to medical implants. In 2021, scientists discovered that sharks’ spiral-shaped intestines work much the same way, favoring fluid flow in one direction—from head to pelvis.

Study: Dental implant surfaces play major role in tissue attachment, warding off unwanted bacteria

The surface of implants, as well as other medical devices, plays a significant role in the adsorption of oral proteins and the colonization by unwanted microorganisms (a process known as biofouling), according to a new study led by the University at Buffalo and the University of Regensburg.
