    N6-methyladenosine (m6A) is a widespread modification on cellular RNA that is dynamically regulated involving m6A writers, erasers and readers, and can impact many cellular processes and pathways. A recent study demonstrates that viruses can use m6A to ensure their RNA avoids innate immune sensing.

    Resistance to antibiotics is a hot topic in microbiology, but there is much less coverage on resistance to vaccines. The associated risk to disease control has potentially devastating implications, but advances are being made towards smarter vaccine design that reduces the risk of antibiotic-resistant disease.

    Mosquitoes have been known for over a century to transmit viruses such as yellow fever. However, laboratory studies to identify the species capable of natural transmission still fail to explain some outbreaks, such as Zika. Now, this paradox is partially explained by a simple methodological shortcoming.

    Two recent studies reveal a virus anti-defence strategy whereby large, ‘jumbo’ phages protect themselves from both restriction endonucleases and DNA-targeting CRISPR–Cas systems, but not from RNA-targeting ones, by encapsulating the phage genome inside the cell in a ‘nucleus’-like shell that is impenetrable for CRISPR effectors.

    Adding a flap on the top of an insecticide-treated bednet helps to intercept blood-seeking mosquitoes and allows a wider range of insecticides to be used together.

    12,13-diHOME produced by the gut microbiome promotes an asthma-like immunophenotype in the lungs of a murine experimental model.

    The Mla phospholipid transporter is a multi-subunit ATP-binding cassette transport system widely understood to move phospholipids in a retrograde direction; that is, from the outer membrane to the inner membrane. However, recent studies reveal that Mla might move phospholipids in the opposite, anterograde direction.

    Since the emergence of methicillin-resistant Staphylococcus aureus 60 years ago, scientists have been trying to engineer β-lactam antibiotics to restore drug susceptibility. Genomic data now shows that clavulanic acid (a β-lactamase inhibitor) can restore susceptibility in many strains, but only if they carry key mutations.
