NASA mirrors on ESA pathfinder to enhance lunar navigation

NASA will supply the upcoming European Space Agency (ESA) Lunar Pathfinder satellite with an array of laser retroreflectors, mirrored devices that reflect light back at its source. The retroreflectors will validate navigation ...

A novel Raman chemical sensor made from noodlelike threads of gold

Researchers created a special ultrathin sensor, spun from gold, that can be attached directly to the skin without irritation or discomfort. The sensor can measure different biomarkers or substances to perform on-body chemical ...

Physicists make leaps in reading out qubits with laser light

Qubits are a basic building block for quantum computers, but they're also notoriously fragile—tricky to observe without erasing their information in the process. Now, new research from the University of Colorado Boulder ...

Physicists build an atom laser that can stay on forever

Lasers produce coherent waves of light: All the light inside a laser vibrates completely in sync. Meanwhile, quantum mechanics tells us that particles like atoms should also be thought of as waves. As a result, we can build ...
