It’s one of the basic facts of science: Heat something and it expands. But a team of US scientists has gone counterintuitive and invented a 3D-printed material that shrinks when heated. Developed as part of DARPA’s program to study materials with controlled microstructure architecture, the lightweight metamaterial exhibits what the researchers call “negative thermal expansion.”

Metamaterials are one of those things that come out of the lab with an air of enchantment about them. Basically, they’re made up of composite materials, like metals, plastics, or ceramics, engineered into repeating, microscopic structures. Depending on how these structures are designed, they can give the metamaterial properties that aren’t found in nature and may not even be derived from the source materials themselves.

The study by a team from the Lawrence Livermore National Laboratory’s (LLNL) Additive Manufacturing Initiative in partnership with the University of Southern California, MIT, and the University of California, Los Angeles, used a 3D printing process called projection microstereolithograpy to form a polymer and a polymer/copper composite into a highly complex 3D bi-material microlattice structure. To put it more simply, they printed a material made of two substances to form a pattern by printing out the polymer in a layer, cleaning the surface to avoid contamination, then printing the polymer/copper composite, then repeating.

ALBANY — While Hillary Clinton and Donald Trump have debated issues such as immigration, gun control, and health care, neither of them has weighed in on the topic of a bill of rights for cyborgs.

Voters chagrined by that oversight do, however, have another option.

PARIS — The European Union’s executive commission on Oct. 26 unveiled a new space strategy that promises public investment to stimulate the creation of space start-up companies.

The Brussels, Belgium-based commission, which acts on behalf of the 28 European Union members — still including Britain for a couple of years — is already the biggest single customer for Europe’s Arianespace launch-service provider and for Europe’s satellite manufacturers.

The EU plans to launch some 30 satellites in the coming decade for the Galileo navigation and Copernicus environment-monitoring programs, which are the major beneficiaries of the commission’s space budget of 12 billion euros ($13.5 billion) between 2014 and 2020.
