Scientists train nano-'building blocks' to take on new shapes

Researchers from the University of Delaware and Washington University in St. Louis have figured out how to train synthetic polymer molecules to behave--to literally “self-assemble” --and form into long, multicompartment ...

Dreamy Lunar Eclipse

Close your eyes, breath deeply, let your mind wander to a distant seashore: It's late in the day, and the western sun is sinking into the glittering waves. At your feet, damp sand reflects the twilight, while overhead, the ...

NASA Helps Texas Respond To Most Widespread Flooding In 50 Years

On July 3, a NASA aircraft equipped with a state-of-the-art sensor provided emergency response officials with critical soil moisture data for several regions across Texas that were threatened by flooding. NASA responded to ...

European heat waves double in length since 1880

The most accurate measures of European daily temperatures ever indicate that the length of heat waves on the continent has doubled and the frequency of extremely hot days has nearly tripled in the past century. The new data ...

Nano-layer of Ruthenium Stabilizes Magnetic Sensors

A layer of ruthenium just a few atoms thick can be used to fine-tune the sensitivity and enhance the reliability of magnetic sensors, tests at the National Institute of Standards and Technology show.

Changing the rings: a key finding for magnetics design

Researchers at the National Institute of Standards and Technology’s Center for Nanoscale Science and Technology have done the first theoretical determination of the dominant damping mechanism that settles down excited magnetic ...
