- The Search For Dark Matter
n experiment called "shining light through walls" would seem hard to improve upon. But University of Florida physicists have proposed a way to do just that, a step they say considerably improves the chance of detecting one of the universe's ...

- 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 ...
