Water At The Nano Scale- More Like Molasses

A Georgia Tech research team has discovered that water exhibits very different properties when it is confined to channels less than two nanometers wide – behaving much like a viscous fluid with a viscosity approaching that of molasses. Determining the pro ...

Ultrashort Light Pulse Blazes New Paths For Science

Researchers in Italy have created an ultrashort light pulse—a single isolated burst of extreme-ultraviolet light that lasts for only 130 attoseconds (billionths of a billionth of a second). Their achievement currently represents the shortest artificial lig ...
