    How Handedness Arises

    UCLA chemists solved a molecular mystery, and report the discovery in the journal Nature Communications.

    Image: Achiral triangles form chiral super-structures.

    Colored patches represent parallelogram outlines around pairs of triangles that have formed chiral super-structures.

    Parallelograms having different 'handedness' and orientations are color-coded and superimposed over each other.

    Xylene from Biomass

    Catalytic Production of Renewable Xylene

    Chemical engineers at UMass Amherst find high-yield method of making p-xylene from biomass.

    Image: Reasearchers investigated a renewable route to p-xylene from biomass-derived dimethylfuran and ethylene with zeolite catalysts.

    Cycloaddition of ethylene and 2,5-dimethylfuran and subsequent dehydration to p-xylene has been achieved with 75% selectivity using a H-Y zeolite and an aliphatic solvent at 300 �C.

  • A New Technique that will Transform Epigenetics Research

    Levels of 5mC and 5hmC chemical modifications

    A New Technique that will Transform Epigenetics Research

    Scientists at the University of Cambridge and the Babraham Institute have demonstrated a new technique that will transform epigenetics research: The quantitative sequencing of 5-methylcytosine and 5-hydroxymethylcytosine at single-base resolution.

    Image: The centre of the diagram shows levels of 5mC and 5hmC chemical modifications along a chromosome (section of DNA). The cycle illustrates that after addition to DNA, 5mC (blue) can be converted to 5hmC (red) and then subsequently removed.
