The first molecular keypad lock

How can defense or intelligence agencies safeguard the security of top-secret data protected by a computation device the size of a single molecule?

Physicists transmit visible light through miniature cable

Physicists at Boston College have beamed visible light through a cable hundreds of times smaller than a human hair, an achievement they anticipate will lead to advances in solar power and optical computing.

Finding Memory in Nonlinear Ionization

David Rayner and his colleagues at the National Research Council (NRC) of Canada in Ottawa have shown that when transparent solids, such as glass, are ionized with short intense laser pulses the material is subtly changed.

Hubble Observations Provide Insight into Planet Birth

Hubble observed a "blizzard" of particles in a disk around a young star, revealing the process by which planets grow from tiny dust grains. The particles are as fluffy as snowflakes and are roughly ten times larger than typical ...

System X Used to Model Behavior of Entire Structures

Elisa Sotelino, professor of civil and environmental engineering at Virginia Tech, has developed a family of parallel algorithms, named Group Implicit Algorithms, which have had a major impact in the nonlinear dynamic analysis ...
