The Science Show gives Australians unique insights into the latest scientific research and debate, from the physics of cricket to prime ministerial biorhythms.

This has been a bumper year for whale-watching on Australia's east coast, with thousands of humpbacks spotted cruising along their annual migration route. 

This population was almost wiped out by whalers last century but has bounced back — and then some. A new estimate suggests there are now more of these humpbacks than in pre-whaling times. 

So why are the eastern Australian humpbacks going gangbusters while other populations aren't doing nearly as well? 

You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia). You'll find episodes on animal behaviour, human health, space exploration and so much more.

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?

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?

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?

More than 30 years ago, astronomers came up with the bold idea to build the world’s biggest radio telescopes.

One is now taking shape in the Western Australian outback, where scientists and engineers are installing more than 130,000 Christmas-tree-shaped antennas onto the red earth.

And those stunning auroras over the past year? There’s a good chance we’ll see more colourful displays in 2025.

All that and more with ABC Science digital executive producer Genelle Weule and University of Sydney astronomer and 2024 ABC Science Top Fiver Dr Laura Driessen.
