Researchers at Cornell University have discovered a way to bind and stack nanoscale clusters of copper molecules that can self-assemble and mimic these complex biosystem structures at different length scales. The clusters provide a platform for developing new catalytic properties that extend beyond what traditional materials can offer.

Scientists have demonstrated that lipid-based nanoparticles carrying two sets of protein-making instructions have the potential to function as therapies for two genetic disorders. In one experiment, the payload-containing nanoparticles prompted the production of the missing clotting protein in mice that were models for hemophilia. In another test, the nanoparticles' cargo reduced the activation level of a gene that, when overactive, interferes with clearance of cholesterol from the bloodstream.

Researchers at Washington State University have made a first step in economically converting plant materials to fuels. One big hurdle is that oxygen has to be removed from the plant materials before they can be used. Iron-based catalysts show promise for removing oxygen, but the iron also oxidizes, or rusts, during the reaction, and then the reaction stops. The researchers discovered that one way around this issue is to get the iron to remove the oxygen from the plant materials without taking up so much oxygen that the reaction stops. This was achieved with an iron-based catalyst surrounded by a thin layer of graphene.

A research team from the Massachusetts Institute of Technology (MIT), DESY (German Electron Synchrotron, in Hamburg), and the University of Hamburg has, for the first time, succeeded in building nanoscale integrated electronic circuits that can capture light with the help of tiny antennas and determine the absolute phase of the light wave.

The mantis shrimp uses its two dactyl clubs to strike prey at over 50 miles per hour without appearing to incur any damage. Researchers at the University of California, Irvine have discovered that the clubs have a uniquely designed nanoparticle coating that absorbs and dissipates energy. The researchers determined that the nanoparticles are spheres made of intertwined organic and inorganic nanocrystals.
