Trump eases US methane rules as Colorado says state's work

The Trump administration is rolling back some U.S. regulations on climate-changing methane pollution, calling them expensive and burdensome, but Colorado says its rules are working—and they have industry support.

Physicists design a nano-resonator with strong nonlinear response

An international research team has found a way to make frequency conversion of light at the nanoscale 100 times more efficient. The new method is based on isolated dielectric nanoparticles supporting so-called bound states ...

Maintaining vibrational coherence with electron spin

Electron spin is an important property that determines processes such as chemical reactivity and the lifetime of the electron state. Spin is exploited in several applications such as luminescent materials, phototherapy, photochemistry, ...

Quantum bits in two dimensions

Two novel materials, each composed of a single atomic layer and the tip of a scanning tunneling microscope, are the ingredients for a novel kind of quantum dot. These extremely small nanostructures allow delicate control ...

Scientists create complex transmembrane proteins from scratch

It is now possible to create complex, custom-designed transmembrane proteins from scratch, scientists report this week. The advance, led by molecular engineers at the University of Washington Institute for Protein Design, ...
