Editor's note

With Snowy 2.0, potentially Australia’s largest pumped hydro project, shaping up as an election issue, we think it’s worth demystifying the function and point of pumped hydro. We’ve paired energy expert Roger Dargaville with our own cartoonist Wes Mountain to create an explainer (and five gifs) that answer the questions you might be too embarrassed to ask: does it create more energy than you put in? Is it really renewable? How does it work, exactly?

If you’re one of the millions of Australians taking pills every day then researchers have come up with a cheap and easy way to make sure you’re taking the correct tablets. And this invention could even be extended for use at festivals for those taking recreational drugs and wanting to know what they contain.

And there’s been some debate over the recent conviction of George Pell – most of it centring on the fact a previous jury could not find him guilty. Today Jacqui Horan sheds some light on how the jury system works – and the fact that it does.

What pill is that? Cheap and easy pill testing could soon be in your own hands

Vassilis Kostakos, University of Melbourne

The technology to identify pills is getting cheaper and smaller. That means it could also be used to test the make-up of illegal pills at festivals and other events.

All about juries: why do we actually need them and can they get it ‘wrong’?

Jacqui Horan, Monash University

A hung jury does not necessarily undermine a verdict in a subsequent trial – it more likely means some of the jurors from the first trial agreed with the final verdict.

  • Rising seas allow coastal wetlands to store more carbon

    One surprising potential benefit of sea-level rise is it helps coastal wetlands store more carbon.
