  1. De-(Ci)-phering the pathways of wing development

    During development, the hedgehog signaling molecule can act through a single version of the Ci protein to regulate the genes that pattern the structure of fruit fly wings.

  2. Kickstarting inflammation

    Different types of chloride channels respond to specific stimuli to trigger the activation of inflammatory proteins.

  3. Getting to the core of nuclear speckles

    Researchers have discovered two proteins that make up the scaffold that holds nuclear speckles together.

  4. Surviving extreme hibernation

    Studying cells from Arctic ground squirrels reveals how these animals might be able to withstand severe oxygen shortages when hibernating during winter.

  5. Did fins evolve from gills?

    Fluorescent skate embryos reveal how fin and gill skeletons develop, shedding light on a hundred-year-old mystery about their evolutionary origins.

  6. Homing in on cancer

    Killer cells in the immune system initiate a coordinated attack against cancer cells by attracting each other and swarming towards the tumour.

  7. Color-coding protein production

    A three-dimensional microscopy technique uses fluorescent tags to study the production of new macromolecules during the regeneration of limbs in salamanders.

  8. Localizing sounds

    Why are humans better at localizing sounds coming from some locations than from others?
