Today’s rubbish may well be the fossils of tomorrow. Plastic bags, old pens, cheap clothing, or even chicken bones are all examples of possible “technofossils”, rapidly accumulating debris and detritus that may come to represent the story of humanity in the geological record long after we’re gone.

But it doesn’t have to be this way. Host Dr Russell Moul speaks to Professors Sarah Gabbott and Jan Zalasiewicz of the University of Leicester, authors of Discarded: How Technofossils Will be Our Ultimate Legacy, about the fascinating processes involved in turning our trash into fossils, but also how interest in these processes may help us change them.

Lining up for your seasonal flu shot is an annual ritual, but what if it didn't have to be this way? Wouldn't it be great if we could develop a universal vaccine that could protect us against all current and future virus strains? Host Laura Simmons speaks to Dr Florian Krammer, a professor in vaccinology at the Icahn School of Medicine at Mount Sinai, to find out just how far humanity has reached in our quest to finally conquer the flu with an all-purpose vaccine.

Language can evolve surprisingly quickly, and nothing has sped it up quite like the invention of the Internet. So, how does it affect how we communicate, not just on our devices but offline, IRL?

Join host Tom Hale, senior journalist at IFLScience, as he discusses this and more with Internet linguist Dr Gretchen McCulloch, where they explore the origins of internet acronyms, interpreting tone via emojis, memes in real life, and the universal need for ironic punctuation marks.
