Researchers at the Department of Energy's Oak Ridge National Laboratory, in collaboration with NASA, are taking additive manufacturing to the final frontier by 3D printing the same kind of wheel as the design used by NASA ...

ExoMars: Back on track for the red planet

A year has passed since the launch of the ESA's Rosalind Franklin rover mission was put on hold, but the work has not stopped for the ExoMars teams in Europe.

Locking and unlocking molecular structures on demand

Researchers at Kanazawa University report in Angewandte Chemie International Edition how the formation and deformation speed of interlocked molecular structures called rotaxanes can be tuned—a discovery that may lead to ...

Unifying colors by primes

Isaac Newton's theory of light indicates that all colors can be generated from three basic colors: red, green, and blue. RGB (Red, Green, Blue), a light-color structure that contains 3×256 values of letter symbols, and CMYK ...

Developing the world's smallest gear wheel

Ever smaller and more intricate—without miniaturization, we wouldn't have the components today that are required for high-performance laptops, compact smartphones or high-resolution endoscopes. Research is now being carried ...

There's a big rock stuck inside one of Perseverance's wheels

It looks like the Perseverance rover has an unwanted passenger, a rock stuck inside one of its wheels. The image of the stone was selected by public input as the "Image of the Week" for Week 54 (Feb. 20–26, 2022) of the ...
