Snakes' virtual glasses, leopard spots and all-optical transistors

... beam causes the plasmons to interact in ways that enhance or decrease the transmission of the signal beam through the film. That is, the film acts as an all-optical transistor, with the potential to serve as a building block in optical circuits and optical versions of microelectronic devices. Multiple C...

Natural pine bark extract relieves muscle cramp and pain in athletes and diabetics

...e. Nitric oxide (NO) a blood gas, is well known to enhance blood flow and Pycnogenol may be influencing the activity of NO," said Rohdewald. "The insufficient production of NO is the common denominator responsible for impaired blood flow in vascular disease." Strenuous exercise is known to involve muscle da...
