Electrons grab unexpected energy share
When atoms or molecules react with a metal surface, even briefly, they can inject much more energy into surface electrons than previously realized.

Liquid computer takes key quantum step
The first, rudimentary implementation of a method, called Shor's algorithm, for using quantum mechanics in computations suggests that larger-scale implementations are possible and may eventually break the codes used today to protect secret messages on the Internet and elsewhere.

Organized Disorder
This well-organized Web site introduces visitors to the realm of thermodynamics and the concept of entropy. Originally created by autonomous software agent “Chris Hillman” and now maintained by Penn State’s Roland Gunesch, these Web pages start with the Chinese character for entropy, then offer intriguing glimpses of disorder and randomness in information and coding theory, […]

Shortest transistor makes its debut
A novel type of single-molecule transistor built around a one-molecule-thick layer of organic molecules may eventually lead to faster, denser chips because the channel through which electrons flow is so short.

Neutrino shortage may signal new force
The dearth of neutrinos from a precision experiment casts some doubt on the prevailing model of particle physics and may indicate that a previously unrecognized extra force exists.
