An asteroid dubbed 2024 YR4 is causing a stir among the space community and a frenzy in the media. It currently has a 2.3 per cent chance of crashing into Earth three days before Christmas in 2032. But this is not our first asteroid rodeo. Get in touch with us: labnotes@abc.net.au

Varroa is the parasite responsible for destroying bee colonies all around the world and is regarded as "the greatest biological threat to Australia's honey bee population."The good news is that some honey bees can fight back. And they're being helped by breeders, scientists and artificial insemination on the tiniest scale.Learn more on Lab Notes, the show that brings you the science of new discoveries and current events.

Unlike other deserts, Australian deserts experience occasional high rainfall. It supports a unique ecology.

Australia's summer UV levels are high enough to cause sunburn in as little as 11 minutes.Yet the summer sun in the Northern Hemisphere rarely feels that full on.So why does our sunlight have that extra "bite"?Spoiler: it's not the hole in the ozone layer.Learn more on Lab Notes, the show that brings you the science of new discoveries and current events.Get in touch with us: labnotes@abc.net.au

Opals, ancient humans and sharks dating back 465 million years. This week we see how today’s world has been shaped from the distant past.

Antarctic krill (Euphausia superba) do much more than fill whales' bellies. These tiny crustaceans also play a huge role in Earth's carbon cycle.They sequester around 40 million tonnes of carbon each year, mostly in their poo — that's the equivalent of taking 35 million cars off the road.Yet there's plenty we don't know about these thumb-sized critters.Now a new study has revealed what they get up to under the Antarctic winter sea ice, and how this behaviour affects carbon calculations.Dive into the secret life of krill on Lab Notes, the show that brings you the science of new discoveries and current events.Get in touch with us: labnotes@abc.net.au

Opalised fossils previously overlooked at the Australian Museum have overturned our understanding of the origin of mammals with the emergence of a whole new age of mammals: The Age of Monotremes.

Robert F Kennedy Jr is tipped to lead the US Department of Health and Human Services. Over the years, RFK Jr has repeatedly pushed the claim that childhood vaccines cause autism spectrum disorder — a theory that's been well and truly debunked.So where did this idea come from? What's bowel disease got to do with it? And what might the US expect with an anti-vaxxer at the helm of health and human services?Learn more on Lab Notes, the new show that brings you the science of new discoveries and current events.

A remote community in the western Pacific is working with scientists to battle the effects of invasive species, a leaking WW2 oil tanker and climate change.
