Key to the achievement is the confinement of photons and molecules in an optical cavity long enough for them to reach thermal equilibrium.

Primarily a tool to produce large amounts of protein quickly, the cell-free system is being adapted to the study of complex biological processes.

The nonlinear optics device could help to resolve one of astronomy’s lingering blind spots.

Completing the global conversion to low-enriched uranium remains many years away for molybdenum-99 production, despite a recent milestone and financial aid from the US. Now the Department of Energy is acting to create a domestic supply source for the isotope.

Smart people are everywhere, but they need resources to realize their talents.

Citing dissatisfaction with an interagency management model, a National Science Board committee refuses to keep the South Dakota project going.

Radar, sonar, and electromagnetic measurements provide complementary information about oceanic processes, properties, and motions.

A phase transition brought on by quantum fluctuations at absolute zero may seem like an abstract theoretical idea of little practical consequence. But it is the key to explaining a wide variety of experiments.

The field of nanoplasmonics is young but rich in phenomena that have inspired practical uses in physics, biomedicine, environmental monitoring, and national security.

Cavitation rheology measures the pressure at which a bubble blown in soft material suddenly expands rapidly. It is gentle enough to allow stiffness measurements of biological materials in vivo.
