Evidence of superionic ice provides new insights into the unusual magnetic fields of Uranus and Neptune

Not all ice is the same. The solid form of water comes in more than a dozen different—sometimes more, sometimes less crystalline—structures, depending on the conditions of pressure and temperature in the environment. ...

A 'sponge' for adsorbing and desorbing gas molecules

A group of researchers led by scientists from the RIKEN Center for Emergent Matter Science and the University of Tokyo has created an unusual material—a soft crystal made of molecules known as a catenanes—that behaves ...

Refuting a 70-year approach to predicting material microstructure

A 70-year-old model used to predict the microstructure of materials doesn't work for today's materials, say Carnegie Mellon University researchers in Science. A microscopy technique developed by Carnegie Mellon and Argonne ...

Researchers reveal a novel metal where electrons flow with fluid-like dynamics

A team of researchers from Boston College has created a new metallic specimen where the motion of electrons flows in the same way water flows in a pipe—fundamentally changing from particle-like to fluid-like dynamics, the ...

A shock-induced mechanism for the creation of organic molecules

Complex carbon-based molecules are everywhere in the Cosmos.  How many of these molecules are formed is still something of a mystery, particularly for carbon molecules formed by nature on primordial Earth that gave rise ...

Table-top electron camera catches ultrafast dynamics of matter

Scientists at DESY have built a compact electron camera that can capture the inner, ultrafast dynamics of matter. The system shoots short bunches of electrons at a sample to take snapshots of its current inner structure. ...
