  1. Sensing the long winter

    New results help to dissect how low temperatures trigger the production of the long noncoding RNA COOLAIR, but cast doubt on its role in vernalization.

  2. Stay in school

    Trout may be able to save energy by swimming directly behind one another when in a school of fish.

  3. Iron overload

    Mitochondrial dysfunction contributes to iron overload and symptoms of brain disease in mice, suggesting potential new approaches to treating age-related brain disease.

  4. Metabolic speed limits

    Changing the amount of specific helper molecules in the cell controls the rate of the metabolic reactions that power life.

  5. The many faces of cancer therapy

    Mesenchymal stem cells make a type of immunotherapy less effective in treating cancer.

  6. The biological basis of predictions

    A computational network designed using the biological features of the hippocampus can generate similar patterns of activity to those observed when the hippocampus of tufted titmouse makes predictions based on memories.

  7. Where did spiders get their venom?

    The vast variety of toxins found in the venom of modern-day spiders evolved from a single small protein around 375 million years ago.

  8. Digesting unhealthy habits

    Genetic variants that predispose people to cigarette smoking increase the risk of developing a wide array of digestive diseases.
