A 3-D model of the brain of a man who lived for 55 years with almost total amnesia is revealing new clues about what caused his memory loss, and could lead to a better understanding of memory, researchers report. Henry Molaison (often ...
A new kind of paper that is made of wood fibers yet is 96% transparent could be a revolutionary material for next-generation solar cells. Coming from plants, the paper is inexpensive and more environmentally friendly than the plastic ...
Heralding a new age of terrific timekeeping, a research group led by a National Institute of Standards and Technology (NIST) physicist has unveiled an experimental strontium atomic clock that has set new world records for both precision and ...
