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.

It's mid-afternoon and time for a treat! Do you choose a healthy piece of fruit, or do you head straight for the chocolate? It turns out that well before we consciously decide what we're going to eat, our brain has already weighed up our choices — and in a fraction of a second. Now a new study shows which food attributes are processed by our brain faster than others, and how this might influence our dietary decisions.

We have a mysterious visitor to our little patch of the cosmos this week: A comet called 3I/ATLAS. This icy, rocky ball is only the third interstellar object we've discovered zooming past our Sun. There are scientists who think the comet may be alien technology sent from another solar system to invade Earth, but space agencies poured cold water on this idea. So how will we know if we truly find evidence of extraterrestrial life?

Around 1.5 million years ago, in what's now Kenya, a human-like figure walked across the savannah. He was probably quite short by our standards, no taller than Danny DeVito. But unlike Danny DeVito, this ancient figure was not human. He was a long-extinct relative of ours called Paranthropus boisei. And now his fossilised hand bones are giving us never-before-seen insights into how he and his species lived.
