There's plenty to celebrate when it comes to Australian science - for a relatively small population, we've made some big contributions to the world, from wi-fi to the bionic ear. But this National Science Week, Swinburne University of Technology in Melbourne is looking back at some of their quirkier research.

1. Chew more, stress less

A Swinburne study found that chewing sugar-free gum reduces anxiety by more than 17 percent during stressful situations. The study also showed that chewing gum increases alertness and improves performance while multi-tasking.

2.  How lunch – not aliens – explained mystery signals at The Dish

Swinburne researchers discovered that mystery radio signals detected at the Parkes telescope were caused by opening the door of a microwave oven.

3.  Explainer: what is insomnia and what can you do about it?

Swinburne researcher, Jo-Anne Abbott, discusses insomnia and an emerging treatment that may help sufferers.

4.  Shared keyboards are breeding grounds for germs

Using simple ethanol-based hand sanitisers and regular cleaning with ethanol wipes can dramatically reduce bacteria on shared computer keyboards. A study conducted by researchers from Swinburne's Environment and Biotechnology Centre proved that these simple measures led to a to a reduced potential health risk.

5. Chocolate really is good for you!
