    As little as one serving of fish per month offers protection against the most common form of stroke.

  8. Earth

    Predicting geomagnetic storms

    Recent observations with an Earth-orbiting spacecraft may provide new ways to predict when solar temper tantrums will cause the geomagnetic storms that disrupt communications systems on Earth and harm satellites.

  9. Animals

    Retaking Flight: Some insects that didn’t use it didn’t lose it

    Stick insects may have done what biologists once thought was impossible: lose something as complicated as a wing in the course of evolution but recover it millions of years later.
