Mimicking termites to generate new materials

Inspired by the way termites build their nests, researchers at Caltech have developed a framework to design new materials that mimic the fundamental rules hidden in nature's growth patterns. The researchers showed that, using ...

Nanoparticles can save historic buildings made from porous rock

Many historical buildings were built of sandstone, including Vienna's St. Stephen's Cathedral. Sandstone is easy to work with, but does not withstand weathering. It consists of sand grains that are relatively weakly bonded ...

NASA's Perseverance studies the wild winds of Jezero Crater

During its first couple hundred days in Jezero Crater, NASA's Perseverance Mars rover saw some of the most intense dust activity ever witnessed by a mission sent to the Red Planet's surface. Not only did the rover detect ...

A new explanation for why Jupiter's moon has splendid dunes

Scientists have long wondered how Jupiter's innermost moon, Io, has meandering ridges as grand as any that can be seen in movies like "Dune." Now, a Rutgers research study has provided a new explanation of how dunes can form ...

Hidden order in windswept sand

An interdisciplinary team including researchers from Leipzig University has analyzed an extensive collection of sand samples from so-called megaripple fields around the world and gained new insights into the composition of ...

Light reveals the origin of a grain of sand

A grain of sand buried for an extended period of time in earthworks or on the bottom of the ocean, accumulate a luminescence signal. Scientists use this signal to determine how long a particular grain of sand has been buried. ...
