Turning cells into computers with protein logic gates

The same basic tools that allow computers to function are now being used to control life at the molecular level. The advances have implications for future medicines and synthetic biology.

Optimizing efficiency of quantum circuits

Quantum circuits, the building blocks of quantum computers, use quantum mechanical effects to perform tasks. They are much faster and more accurate than the classical circuits that are found in electronic devices today. In ...

An all-electric magnetic logic gate

A team of researchers from ETH Zurich and the Paul Scherrer Institute has developed a way to build an all-electric magnetic logic gate. In their paper published in the journal Nature, the group describes their device and ...

New book debunks myths about who causes crime and why

Forty years ago, Craig Haney was a young professor of psychology at UC Santa Cruz when a question about the real causes of crime began to form in his mind: What if most violent criminal behavior is rooted in early childhood ...

Quantum computers offer another look at classic physics concepts

"Think what we can do if we teach a quantum computer to do statistical mechanics," posed Michael McGuigan, a computational scientist with the Computational Science Initiative at the U.S. Department of Energy's Brookhaven ...

Quantum Hall-based superconducting interference device

In a recent report published on Science Advances, Andrew Seredinski and co-workers presented a graphene-based Josephson junction with dedicated side gates fabricated from the same sheet of graphene as the junction itself. ...
