Researchers create 'impossible' nano-sized protein cages with the help of gold

Researchers from an international collaboration have succeeded in creating a "protein cage"—a nanoscale structure that could be used to deliver drugs to specific places of the body, and which can be readily assembled and disassembled, but also withstands boiling and other extreme conditions. They did this by exploring geometries not found in nature reminiscent of "paradoxical geometries" found in Islamic art.

Physicists propose perfect material for lasers

Weyl semimetals are a recently discovered class of materials in which charge carriers behave the way electrons and positrons do in particle accelerators. Researchers from the Moscow Institute of Physics and Technology and Ioffe Institute in St. Petersburg have shown that these materials represent perfect gain media for lasers. The research findings were published in Physical Review B.
