Close-ups of grain boundaries reveal how sulfur impurities make nickel brittle

University of California San Diego

Engineers at the University of California San Diego have shed new light on a scientific mystery regarding the atomic-level mechanism of the sulfur embrittlement of nickel, a classic problem that has puzzled the scientific community for nearly a century. The discovery also enriches fundamental understanding of general grain boundaries that often control the mechanical and physical properties of polycrystalline materials.

Researchers Find Hidden Signals in RNAs that Regulate Protein Synthesis

Case Western Reserve University

Scientists have long known that RNA encodes instructions to make proteins. The building blocks that comprise RNA—A, U, C, and Gs—form a blueprint for the protein-making machinery in cells. In a new study published in Nature, scientists describe how the protein-making machinery identifies alternative initiation sites from which to start protein synthesis.
