Hunting a creature that hunts me: Collecting ticks for research

It's a sweltering summer afternoon. I'm pushing aside tree limbs and crunching leaves to get back to the trap that I baited two hours ago with dry ice to attract ticks. When I get closer, I can see a gossamer mist hovering ...

How the natural 'glazes' on the walls of Kimberley rock shelters help reveal the world the artists lived in

The Kimberley region is host to Australia's oldest known rock paintings. But people were carving engravings into some of these rocks before they were creating paintings.

Ultra-thin, gas-tight coatings for PET bottles

If polymers are specifically made to form and deposit on the surfaces surrounding the plasma, they can be coated in a targeted manner. Thanks to this so-called plasma enhanced chemical vapor deposition, or PECVD for short, ...
