  • Let the sun shine in! (to your retinal ganglion cells)
    We've covered the detriments of night-time blue light before, but how important is getting blue light during the work day? This controlled trial looked at its effect on working memory.
  • Heritable bacteria
    How can researchers figure out the role of your genetics in determining the kinds of bacteria you have in your gut? Get over a thousand sets of twins and do some fancy testing. We describe the results here.
  • Dampening exam anxiety with probiotics

  • Could fasting help treat MS symptoms?
    Multiple sclerosis involves immune attacks on the nervous system. Current treatments address symptoms, but may have substantial side effects. Fasting diets may both help symptoms and regeneration of existing damage.
