Remembering…
A study published in Science Advances found that certain types of materials have a “memory” of how they were processed, stored, and manipulated. Researchers were then able to use this memory to control how a material ages and to encode specific properties that allow it to perform new functions. This creative approach for designing materials…

Reverse evolution 2.
Turtle ant soldiers scuttle to and from sporting shiny, adorably oversized heads, which they use to block the entrances of their nests — essentially acting as living doors. Not all heads are shaped alike: some soldiers have ones that resemble manhole covers and perfectly seal tunnel entrances. Others have square heads, which they assemble into…

Eternal river… For ever changing…
Ancient Egyptians considered the Nile river to be the source of all life. The steady northward path of the river has nourished the fertile valleys of northeast Africa for millions of years and in doing so, shaped the course of human civilization. The Nile’s unchanging path, however, has been a geologic mystery because long-lived rivers…

Chairs into tables…
Turning a chair into a table, or vice versa, might sound like somewhat of a magic trick. In this case, zero magic is involved, just plenty of complex geometry and machine learning. Called LOGAN, the deep neural network, i.e., a machine of sorts, can learn to transform the shapes of two different objects, for example,…

Eternal vortices. Ephemeral cosmos.
In 1949, famous physicist Lars Onsager published a paper discussing the potential implications of superfluids and turbulence. Now, 70 years later, a team of Australian researchers has conducted an experiment to back his theory – using a tiny quantum version of Jupiter’s ‘Great Red Spot’ to do it. Unlike the Great Red Spot, for this…
