  • Quantum interference in charge transport is attracting interest with applications in nanoelectronics and quantum computing. Here, the authors present a method for quantifying electronic transmission through molecules, and demonstrate constructive quantum interference in a molecule with two identical, parallel coupling paths.

  • Correlating aromatic carbons attached to fluorine with meta-position hydrogens in fluorine-labelled phenylalanines can yield two-dimensional correlations with narrow linewidths in large proteins. Adapting phenylalanine-tRNA synthetase increases the incorporation rate, while expanding the genetic code enables site-specific incorporation of fluorinated phenylalanine. The resulting HCF-transverse relaxation-optimized spectroscopy can illuminate protein dynamics and drive multiplexed drug discovery campaigns.

  • Animals of many kinds can orient themselves with respect to the Earth's magnetic field. Magnetic orientation seems to be through the eye, possibly by the magnetic modulation of a photochemical reaction. The problem is that nobody knows whether such modulation is even possible, for any chemical system, as that the Earth's magnetic field is relatively weak. This paper presents evidence that weak magnetic fields can modulate photochemical reactions in the expected manner. The model system is entirely artificial, and the temperature rather low, but the point has been made.
