How do scientists know evolution is real?

The idea of evolution – that species change and evolve over time – is the foundation of biology. But how do scientists actually know it’s real? Why This Matters: It’s one of the central theories of science, yet also one that some people find controversial. In science, we look at the evidence and try to find the theory that best explains it. And that’s what happened when it came to figuring out evolution. We can […] See more

Incredible modular microfactory turns plastic recycling on its head

A microfactory that transforms recyclables into useful plastic products has opened in Sydney, with a design that is endlessly customisable – and cheap to build. Why This Matters: These microfactories might just be the answer to our waste crisis. In 2018 China stopped buying our recycling. Then, in July of this year, Indonesia started turning it back by the container load. With our recycling waste back on our shores, our nation was hurled head-first into an […] See more

Do you know where your online data is?

Worth more than oil and gold, our online data is taken freely and willingly. But can we go offline when the world is switched on? Why This Matters: It’s practically impossible to stop someone collecting your data. With our personal data constantly gathered and analysed, it’s the grim reality that the internet knows you better than you know yourself. As technology follows our patterns, in turn, it can predict our behaviour. “To understand someone, it’s […] See more

Death by BBQ - is meat really killing us?

A series of new reviews reveals that meat might not be all that bad for us, but other experts aren’t completely convinced. Why This Matters: Recommendations need to be backed by evidence, but the interpretation of the evidence can cause issues. Aussies everywhere love a good BBQ, but should we be worried about eating all that meat? Perhaps not, according to a new series of reviews which have found that there are very few health […] See more

The engineer using nanotechnology to mend broken hearts

Hossein Tavassoli is working to mend broken hearts using an incredible nanotech breakthrough – and he wants to tell the world. Why This Matters: Discoveries in the lab aren’t useful if you can’t communicate them. When Hossein Tavassoli first told his mother that he was researching heart disease, she responded with “But, you’re an engineer…” She was right, of course – Hossein’s undergraduate degree was in material engineering – but at the time, he found […] See more

A new 'iron dragon' pterosaur

A newly described species suggests that Aussie pterosaurs might have lived longer than we thought. Why This Matters: Australia’s prehistoric history continues to evolve and take flight. The pterosaurs – the earliest vertebrates known to have evolved the ability to fly – are a powerful and frequent symbol of the age of dinosaurs. Pterosaurs have been discovered on every continent but the fossil record is remarkably small. Pterosaur bones are thin and hollow and their remains […] See more

How measles impacts your immune system

Measles isn’t a mild disease, it can be fatal. While some symptoms are visible, there are invisible effects that can leave you vulnerable to other serious infections. Why This Matters: The measles virus itself is not the only thing to worry about if you get infected. For people who grew up prior to 1966, getting measles during childhood was so commonplace, it may have seemed like a mild disease: everywhere, children were getting sick, but […] See more

Who is most at risk of measles

It’s not just an unvaccinated person who poses a risk, many people might be under-vaccinated and not realise it. Why This Matters: Some people, like pregnant women, can’t be vaccinated, and even you could be under-vaccinated without realising. It may seem easy to only blame the anti-vaccination movement for the recent rise in measles outbreaks in developed countries. While vaccine resistance may be an important contributor to the problem, it’s important to realise that it’s […] See more

Shark nets don't necessarily make Aussie beaches safer

Shark nets, drumlines and culls are a costly, ineffective way of protecting beach goers from sharks – let’s try being smart. Why This Matters: We need to keep beach-goers safe, but we also have to protect threatened and endangered species. Most of the 24 million annual visitors to Queensland don’t notice the series of seemingly innocuous yellow buoys at many popular beaches. Beneath the waves lies a series of baited drumlines and mesh nets that […] See more

Galaxy surrounded by a surprising calm bubble of gas

Astronomers studying the outskirts of a distant galaxy have discovered that the galaxy sits in a serene ocean of gas. Why This Matters: In a weird universe, this is an area of quiet calm. A massive galaxy, which is about four billion light-years from Earth, is surrounded by a halo of gas that is much less dense and less magnetised than expected. Previously, halos of gas surrounding galaxies were thought to be turbulent and stormy. […] See more

Adding nature to our grand designs

Incorporating nature into our urban landscapes is more than just adding a few pot plants. Why This Matters: Getting back to nature doesn’t necessarily mean getting out of town – and that could improve health and wellbeing. With all the hype over boosting the well-being of city workers and dwellers, it’s common to see splashes of greenery throughout our urban environment. But is adding a few pot-plants to the office really going to make a […] See more
