A team from Georgia Institute of Technology has developed a way to use 3D printers to create objects capable of expanding dramatically that could someday be used in applications ranging from space missions to biomedical devices. The new objects use tensegrity, a structural system of floating rods in compression and cables in continuous tension. The researchers fabricated the struts from shape memory polymers that unfold when heated.

An international team led by the University of Bern and the National Physical Laboratory (NPL) has revealed a new way to tune the functionality of next-generation molecular electronic devices using graphene. The results could be exploited to develop smaller, higher-performance devices for use in a range of applications including molecular sensing, flexible electronics, and energy conversion and storage, as well as robust measurement setups for resistance standards.

The different rates of neutrino and anti-neutrino oscillations recorded by an international collaboration of researchers in Japan—including from Kavli IPMU—is an important step in the search for a new source of asymmetry in the laws that govern matter and antimatter. The Standard Model of particle physics describes the basic building blocks of matter and how they interact. It also makes a point that for every particle created, there is an anti-particle...

Researchers have studied how light can be used to “see” the quantum nature of an electronic material. They managed to do that by capturing light in a net of carbon atoms and slowing down light it down so that it moves almost as slow as the electrons in the graphene. Then something special happens: electrons and light start to move in concert, unveiling their quantum nature at such large scale that it could observed with a special type of microscope.

The experiments were performed with ultra-high quality graphene...
