Governments would benefit from agreeing common principles for developing and communicating scientific advice, both in crisis situations and for long-term policymaking, according to a new OECD report. In light of recent controversies around science advice, the report proposes a checklist for countries to follow to ensure science advisory processes are effective and trustworthy.

Lawrence Livermore researchers have made graphene aerogel microlattices with an engineered architecture via a 3D printing technique known as direct ink writing.

This is a view of the localized electrons in the unusual insulating state of Li under pressure, courtesy of Russell Hemley and Ivan Naumov.

Printed silicon on paper Caption: High-moiblity polysilicon layer was directly formed on paper by coating liquid silicon, which was annealed by pulsed laser-light.

A three-dimensional interpretation of "event zero." The frequency increases slowly as the electron loses energy, ending in the first of six or possibly seven visible frequency jumps before the electron is ejected from the trap.

Chemical phase map shows how the electrochemical discharge of iron fluoride microwires proceeded from 0 percent discharge (left), to 50 percent (middle), to 95 percent (right).

This shows the heterogeneous electronic density created by the diverse molecular orientations at the liquid-vapor interface of water.
