Atomic beams shoot straighter via cascading silicon peashooters
To a non-physicist, an "atomic beam collimator" may sound like a phaser firing mystical particles. That might not be the worst metaphor to introduce a technology that researchers have now miniaturized, making it more likely ...

High-fidelity simulations point the way to optimizing heat transfer in current and next-generation reactors
Engineers must manage a maelstrom in the core of operating nuclear reactors. Nuclear reactions deposit an extraordinary amount of heat in the fuel rods, setting off a frenzy of boiling, bubbling, and evaporation in surrounding ...

Droplet trains reveal how nature navigates blood traffic
Nearing a decision point, online traffic maps recommend a less-crowded route over the other ways with several slow spots. For most of us, the choice seems clear. Still, have you ever wondered whether this collectively preferring ...

Repelling charges prevent Cooper pairs from 'island hopping' in insulating state
Superconductors are able to conduct electricity with zero resistance thanks to Cooper pairs, electron duos that team up and skate through a material unimpeded. In 2007, Brown University researchers made the surprising discovery ...

Light-based computer hardware that can compete with silicon
A team of researchers at NTT Corporation has developed a way to use light-based computer hardware that allows it to to compete with silicon. In their paper published in the journal Nature Photonics, the group describes their ...
Study shows the difference between classical flows and superfluid helium in 3-D counter-flow
Researchers at the Weizmann Institute of Science, the University of Rome, CNRS and the University of Helsinki have recently carried out a study investigating the difference between 3-D anisotropic turbulence in classical ...
