Search and Discovery
The multiyear effort that identified the candidate interstellar grains was, in part, a triumph of citizen science.
Organic chemistry and surface science combine to overcome a long-standing materials challenge.
Issues and Events
For 50 years the International Centre for Theoretical Physics has hosted scores of scientists and students at its campus in Trieste, Italy. It now hopes to replicate that model at regional partner institutions.
Cold-atom interferometry, microelectromechanical systems, signals of opportunity, and atomic clocks are some of the technologies the defense agency is pursuing to provide precise navigation when GPS is unavailable.
Researchers say they are preparing the way for scientific exascale computing.
Climate change is a complex and contentious public issue, but the risk-management options available to us are straightforward and have well-characterized strengths and weaknesses.
Impurities in a crystal lattice are the key ingredient in recent efforts to control and apply the coherence and entanglement of spins in condensed-matter systems.
The core principles that underlie quantum weirdness also explain why only selected quantum states survive monitoring by the environment and, as a result, why we experience our world as classical.
