  1. First-class deliveries in cells

    Mesenchymal stem cells are used in a new approach to deliver therapeutic gas molecules without using a toxic artificial carrier.
  2. Overcoming cancer resistance

    Combining an experimental drug with an existing cancer treatment could help to treat a subtype of breast cancer that has become resistant to standard therapies.
  3. Who is calling?

    A new system makes it easier for scientists to assign ultrasonic vocalizations to the correct animal within a pair or group.
  4. Harnessing natural resistance

    A natural molecule in the wild relative of the potato may help make crops resistant to early blight disease, Colorado potato beetle, and potentially other fungi and pests.
  5. Understanding infertility in men

    Male mice that lack the PARL enzyme are infertile due to defects in cell units known as mitochondria.
  6. Closing the ring

    Pigments called carotenoids regulate photosynthesis in a bacterium by altering the architecture of a ring structure in the machinery that harvests energy from the sun.
  7. An unexpected role for neutrophils

    Immune cells generally thought to fight off infections can also help dispose of dead cells, potentially protecting the body from autoimmune disorders.
  8. Spectral signatures

    Information contained in the fMRI signals recorded when the brain is at rest helps to better interpret how changes in blood flow correlate with neural activity across various regions.
