Key early steps in gene expression captured in real time

On scales too small for our eyes to see, the business of life happens through the making of proteins, which impart to our cells both structure and function. Cellular proteins get their marching orders from genetic instructions ...

Insights through atomic simulation

A recent special issue of the Journal of Chemical Physics highlights Pacific Northwest National Laboratory's (PNNL) contributions to developing two prominent open-source software packages for computational chemistry used ...

Solving materials problems with a quantum computer

Quantum computers have enormous potential for calculations using novel algorithms and involving amounts of data far beyond the capacity of today's supercomputers. While such computers have been built, they are still in their ...

Researchers building a harder diamond, called pentadiamonds

Researchers at the University of Tsukuba used computer calculations to design a new carbon-based material even harder than diamond. This structure, dubbed "pentadiamond" by its creators, may be useful for replacing current ...

Dual personalities visualized for shape-shifting molecule

Australian and US researchers have made a breakthrough in understanding the structure of a key genetic molecule, called RNA, and revealing for the first time how these changes impact RNA's function.

Towards a nanomechanical quantum switchboard

Physicists at Universität Regensburg have coupled the vibrations of a macromolecule—a carbon nanotube—to a microwave cavity, creating a novel and highly miniaturized optomechanical system. The team of Dr. Andreas K. ...

Quantum computers flip the script on spin chemistry

To build cheaper and more efficient sustainable energy options, we need to know a lot more than we currently do about the chemical reactions that convert solar energy into electricity. One of the best ways to do that is through ...
