  1. To remove or not to remove

    Maybug larvae can use their digestive enzymes to feed on toxic host plants, but the effects of these enzymes may make the plant less appetizing.
  2. Flipping the photosynthesis switch

    A molecular tag turns photosynthesis on and off by changing the colour of leaves.
  3. Getting a new perspective on antiviral drugs

    A new tool for studying how nucleotide analogs inhibit the virus SARS-CoV-2 could lead to more effective treatments for COVID-19.
  4. Evaluating experimental results from a new perspective

    A new statistical approach that focuses on individual participants rather than population averages could help address issues of replication in psychology and neuroscience.
  5. Doubling life near death

    Removing a key protein from the worm Caenorhabditis elegans near the end of its live can double the worm’s lifespan, demonstrating that life-extending interventions can be made at any age.
  6. Motor connections

    Computer models of nerve cell circuits in growing zebrafish show how the maturing spinal cord controls swimming behaviors.
  7. Predicting a gene switch

    A new metric called information content could help predict whether a region of the genome will repress or activate the activity of the genes it controls.
  8. Probing mouse fertility

    The protein PRMT5 is important for the development of healthy follicles in the ovaries.
