Scientists have created a sensor so accurate it can now measure the weight of a single proton. The super scale uses the smallest unit of mass as a measurement, a single yoctogram, whereas previous sensors could only get within 100 yoctograms — a large margin at that scale.

It seems like carbon nanotubes are capable of doing just about anything we ask them to, from making space elevators a reality to ushering in the next generation of energy storage systems. They also have lots of biological applications, and researchers at Stanford are using fluorescent ones to see inside the bodies of living animals.

By converting some of the wires inside memory chips into carbon nanotubes, researchers say that they could boost the battery life of cell phones and laptops and other mobile electronics by a factor of 100.
