    Pristine molybdenum disulfide undergoes oxidation at its basal plane, such that some S atoms are replaced with O atoms. This new doped monolayer exhibits improved activity for electrocatalytic hydrogen evolution.

    Chiroptical molecular switches change chirality in response to light. Christian Petermayer and Henry Dube report a new type of hemiindigo photoswitches that feature axial chiral substituents and are characterized by an unusual decoupling of the absorption and the circular dichroism (CD) spectra.

    Mechanical gating of a photochemical reaction has been realized by constructing a norbornene that, when subjected to tensile stress, undergoes fission into a UV-light-sensitive diarylethene.

    The modification of DNA at cytosine and thymine, such as methylation, hydroxylation and formylation, might have epigenetic roles. In this Review, the authors discuss established and newer methods for the detection of these modifications in genomic DNA.

    This Perspective describes the physical molecular driving forces that stabilize native lignocellulosic plant biomass structures and govern thermochemical biomass pretreatments. Understanding these driving forces can help us to design efficient methods for deconstructing biomass into biofuels and other bioproducts.
