    Flexible nitrogen utilisation by the metabolic generalist pathogen Mycobacterium tuberculosis

    Aleksandra Agapova et al.
    Metabolomics and stable isotope labelling studies of virulent Mycobacterium tuberculosis reveal a de-centralised metabolic network able to utilise various amino acids as nitrogen sources to a better extent than ammonium.

    Health benefits attributed to 17α-estradiol, a lifespan-extending compound, are mediated through estrogen receptor α

    Shivani N Mann et al.
    17α-Estradiol, a life-span extending compound, signals through estrogen receptor α (ERα) in the liver and hypothalamus to elicit health benefits in a sex-specific manner.

    Metabolic co-dependence drives the evolutionarily ancient Hydra–Chlorella symbiosis

    Mayuko Hamada et al.
    The symbiotic relationship between Hydra and Chlorella is driven by metabolic co-dependence and characterized by changes in the photobiont genome in terms of lack of genes essential in free-living algae.

    Ammonium Transporters: A molecular dual carriageway

    William J Allen, Ian Collinson
    In order to enter a cell, an ammonium ion must first dissociate to form an ammonia molecule and a hydrogen ion (a proton), which then pass through the cell membrane separately and recombine inside.
