NIST Researchers Link Cutting-Edge Gravity Research to Safer Operation of Construction Cranes

February 17, 2022

In the beginning, all that Stephan Schlamminger wanted to do was to write down an equation that would help him obtain a more precise value for G, the

The Case of the Cloudy Filters: Solving the Mystery of the Degrading Sunlight Detectors

March 25, 2021

More than 150 years ago, the Sun blasted Earth with a massive cloud of hot charged particles. This plasma blob generated a magnetic storm on Earth that caused

NIST Publishes a Beginner’s Guide to DNA Origami

January 8, 2021

In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3D structures, including miniature
