Researcher sees survival story in fly’s small genome

By Eric Sorensen, WSU science writer

KelleyPULLMAN, Wash. – Few animals can boast of being as tough as the Antarctic midge. Its larvae develop over not one but two Antarctic winters, losing nearly half their body mass each time. It endures high winds, salt and intense ultraviolet radiation. As an adult, the midge gets by without wings and lives for only a week or so before starting the life cycle all over again. » More …

Tick expert cracks tough cases

The right way to remove a tick


Contrary to folklore, do NOT apply nail polish, petroleum jelly or a burned-out match to an attached tick, as its mouthpart can remain embedded in the skin. Instead:

Using fine-tipped tweezers, grasp the tick as close to the skin’s surface as possible.
