Plasma wakefield acceleration shows promise
When electrons are precisely positioned in a region of high electric field, they can pick up a lot of energy in a small space.
Rewriting the rules of kirigami
Practiced on a lattice instead of paper, the art of cutting, folding, and pasting takes on new scientific significance.
Chemical gardens grown in flatland
When certain inorganic reactions are confined to a two-dimensional cell, the mineral precipitates conform to a simple geometric model.

Online metrics show who’s saying what about scientists’ research
Journal websites are now highlighting their articles’ likes, shares, and tweets, but information scientists still aren’t sure what the numbers really mean.
Brilliant new x-ray source is up and running at Brookhaven
The National Synchrotron Light Source II will produce intense beams to reveal details of complex materials.
China carves out larger role in underground science
As it is doing in so many areas of science, China is racing onto the world stage of underground astroparticle physics.
DOE takes another step toward exascale computing
New supercomputers will allow more detailed simulations for nuclear weapons research and a range of scientific applications.

Upwelling in the Southern Ocean
Because deep water in the Southern Ocean is cold, centuries old, and rich in nutrients, its circulation exerts an outsized influence on Earth’s heat balance, the carbon cycle, and much of ocean biology.
The origin of quark color
Some 50 years ago, just for fun, I began playing around with different types of particle statistics. Those investigations led to a surprising application.
Quantum black holes
Living in a middle ground between the light fundamental entities of particle physics and the massive black holes of astrophysics are objects that trap light but don’t obey classical rules.

The measurement Einstein deemed impossible
Particles undergoing Brownian motion move with constant velocity between Brownian kicks. Albert Einstein predicted the velocity distribution, but he wrongly thought his result would never be experimentally confirmed.
