Hunting Celestial Flashes
Deep in the Siberian taiga, there are a hundred light traps: each about the size of a small table, but together they cover a square kilometer. At night, these traps gaze at the sky, catching faint flashes of light born when cosmic particles slam into the atmosphere. The setup is called TAIGA-HiSCORE, and it usually works as a giant "eye" for such particles.

Two Seismographs on One Shore: How Ice Cores Hear Different Oceans
On the coast of Dronning Maud Land, two ice cores stand like two seismographs on one shore. One, FK17, was drilled on the crest of the Lokenryggen ice rise; the other, TIR18, on the crest of Hammaryggen. A hundred kilometers apart, they catch different tremors of the climate. One hears the Pacific, the other the Atlantic and Indian Oceans.

A Wide-Angle Lens for the Subatomic World
At Jefferson Lab, electrons are accelerated to 12 GeV and smash into protons to pry out their secrets.

Electron scattering is the main tool, but statistics are insufficient for subtle effects.

A Quantum Sieve for the Power Grid

In quantum networks, where nodes exchange Bell pairs, the traditional approach resembles a patient assembler who waits until all pieces are on the table before starting.

X-ray Without a Camera: How to Film a Spinning Engine
An X-ray image is like a photograph taken in the dark with a very short flash: anything that moves comes out blurred. Conventional X-ray detectors are large arrays of millions of pixels, and by the time they read out one frame, the next is already missed. For a spinning turbine or a beating heart, such sluggishness is a death sentence. A team of researchers sidestepped this problem by ditching the array altogether.
