The BA, as it was known, established in 1831, was set up to advance science in the interest of the people, old and young, professional and lay. So, how well is it doing now amid international turmoil.

For decades, climate scientists have been tracking a curious phenomenon. Carbon dioxide levels in the atmosphere are steadily increasing overall but they also rise and fall in an annual rhythm — like the planet is breathing. Each spring, in the southern hemisphere, carbon dioxide levels start to plateau or maybe even drop slightly before shooting up again after summer. So what's driving these seasonal changes?

Iconic jellyfish in saltwater lakes are disappearing.

If you've been watching the Women's Rugby World Cup, you may have noticed players have been wearing special mouthguards that light up when they've suffered a significant knock to the head. It's the first time these concussion-predicting mouthguards have been trialled at a major competition. So in the wake of recent concussion concerns, from professional AFL and rugby league to community competitions, is this the future of sport?

Sophie Ly takes us to Palau to meet scientists and traditional knowledge custodians who are working together to uncover the secrets of Palau’s ancient terraces.

Australia’s known for having some of the world’s toughest sunscreen standards, but in June, that reputation was rocked.  Independent testing of 20 sunscreens found 16 did not meet their advertised SPF50 rating, including three children's sunscreens and three sold by the Cancer Council.  So how are sunscreens tested, and what can we learn from these recent SPF revelations?

Just as quantum physics is poised to launch computing into a new era of capability, researchers are seeing the first signs of quantum effects in biology.

When you think of leaders in the space sector, big hitters like NASA and private companies like SpaceX spring to mind. But since the very beginning of the Space Age, Australia has played a role in the space flight industry. And this year, an Australian company tried to launch a rocket from Australian soil. So why is Australia building and launching rockets at all, especially when so many nations are already miles ahead?

As The Science Show concludes its celebration of 50 years, we remember John Clarke’s contributions to early Science Shows and point to a film just released looking at John’s life, produced by his daughter Lorin.

One in four Australians get hay fever, and as the planet warms, our seasonal sneezes and sniffles are tipped to get much, much worse. 

Join us for highlights from fifty years of The Science Show including Fred Dagg, who helps us with the big questions: what is it all about and why are we here?

Every now and again, dozens or even hundreds of perfectly healthy looking whales strand themselves on a beach. Scientists have a few theories on why they do this. 

Samples from asteroids have helped build a theory of the origin of complex molecules and how they made it to Earth.

Fresh Australian dietary guidelines are due next year, and they’ll likely focus on the health of the planet as well as people.

Small chemical groups inserted or removed from around DNA may affect gene expression and so be a way to control genetic blood disorders such as sickle cell anaemia and beta thalassemia. 

Meat ants don't sound like the most endearing Australian animals. These purple-red insects are super territorial, swarming and biting anything that threatens their nest.  But it turns out they're not just aggressive, flesh-tearing fighters. They're also farmers, architects, and — best of all — cane toad exterminators. 

Is the US shooting itself in the foot, or shooting itself in the head? As Donald Trump removes funding for medical research, climate research and more, Matthew England reflects on how science will help us cope with a changing world.

It's impossible to escape microplastics. They're in our food and water, and the air around us is teeming with them. So considering they're all around us, how can we minimise our exposure to tiny plastic fragments without resorting to living in a cave?

A 100-yr flood is now a more regular occurrence in the German town of Passau, bringing widespread destruction, another local impact of a planet getting hotter.

It feels like you can't go a week without hearing about some new quantum technology which promises to change our lives for the better.  But quantum mechanics is already well and truly present in our daily life — and you don't even have to be a physicist to be using it.
