The next time you pick up a bag of spuds from the supermarket or fill up the car with petrol, you can thank the Treaty of the Metre for the metric system that underpins daily life. The treaty was signed exactly 150 years ago, when delegates from 17 countries gathered in Paris to establish a new and standardised way of measuring the world around us. But the metre's inception predates the treaty that bears its name by nearly 100 years. So how did it come about, and how has its definition changed over the centuries? This episode was first broadcast in May 2025. You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia).

Every now and again, dozens or even hundreds of perfectly healthy looking whales strand themselves on a beach. And despite people's best efforts, many — if not all of them — will die. So why do whales strand themselves, and why do they seem to do it at the same locations? This episode was first broadcast in August 2025. You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia).

Retiring Vice Chancellor of the University of South Australia David Lloyd awarded Pratchett two honorary degrees. In exchange, the author honoured the university with a special scholarship – to be offered every year forever. This week David Lloyd explains his enthusiasms for the Discworld author in front of a packed audience at the Hawke Centre in Adelaide.

A huge cold blob of air above Antarctica and bushfires spreading along ridgelines don't appear to have anything in common, yet the strange behaviour of these natural phenomena — and many others — can be understood and explained by mathematics. You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia).

Step into the supermarket and there's plastic around just about everything, even mangoes — and not all that packaging will be properly disposed of.So with around 20 million tonnes of plastic polluting the environment each year, not to mention the potential health effects of microplastics, is there a better, more environmentally friendly alternative?You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia).

Astrophotographers have had another great month, with the aurora australis lighting up night skies as far north as southern Queensland.And while you might've heard that the best of this bunch of auroras is behind us, don't put your camera away just yet. There's good reason to think the southern lights will illuminate the sky well into 2026.It all depends on what the Sun shoots in our direction … and we might find ourselves in the firing line more often over the next few months.You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia).

It looks like most of Australia is in for a warmer-than-usual summer this year.That's according to the Bureau of Meteorology's long-range forecast, which was released in October.So — without a crystal ball — how do meteorologists make weather predictions so far out, how accurate are they, and how is climate change affecting them?You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia).

In just 75 years the Earth’s average temperature is predicted to be close to 3 degrees above pre-industrial levels. We are in the fast lane to a different world, one that will not be friendly to the current range of plants and animals, including humans. The race is on to cool our overheating planet.

Thanks in part to 18th-century nuns, we now know that having children and breastfeeding reduces a mum's risk of developing breast cancer for years, even until her kid is well into primary school.Now Australian scientists have discovered how breastfeeding specifically enlists the immune system to protect against an aggressive and hard-to-treat type of breast cancer.You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia).
