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

Strewn throughout the sands of an island in the Great Barrier Reef, shards of pottery lay for thousands of years before an archaeologist quite literally stumbled across them 20 years ago.As more pieces were lifted from the sand, a question was also raised: Who shaped and fired these clay pots?We also get to the bottom of a strange phenomenon that had the earth ringing like a bell for nine days -- and earthquake scientists abuzz for a year.Solve these mysteries and more with science reporters Jacinta Bowler and Carl Smith.

Hollywood promoted her as the most beautiful woman in the world. But Hedy Lamarr was more than good looks. She invented and patented a new form of communication which is used widely today and even allows mobile phones to work.

Do you get texts telling you there’s an unclaimed parcel waiting for you at the post office?Turns out scammers can find out if we’re expecting something in the post and time a scam text to coincide with our online purchases -- and it could all be completely legal.And while 2024 saw advances in artificial intelligence, they didn’t seem to wow us like they did in 2023. Are we simply harder to impress now?Breaking all this down -- and more -- are technology reporters Ange Lavoipierre and James Purtill.

CRISPR is the most powerful means of gene editing ever developed. It led to Jennifer Doudna and Emmanuelle Charpentier being awarded the Nobel Prize for chemistry in 2020. Jennifer Doudna speaks with Merlin Crossley about CRISPR, its capability, and the ethical questions which arise.

Up with the sparrows or hanging with the night owls: we humans like to put ourselves into one of two camps.But when it comes to native animals, this idea of either being awake during the day or at night just doesn’t hold up.And while cane toads have already traversed most of northern Australia, there is an ambitious project to stop the pests from infiltrating the Pilbara -- but time is running out to put the plan in motion.We chat all things nature with environment reporter Peter de Kruijff and ABC presenter and nature nerd Dr Ann Jones.
