Graphene has been hailed as a super material since its synthesis in 2004. But, unbeknownst to us, nature has long-been producing graphene, right under our noses. Understanding natural graphene production could revolutionise the way we create this remarkable material.

A roarsome discovery of two previously unknown sabre-toothed cat species in South Africa provides insights into their cheetah-like and leopard-like lifestyles. The finding challenges our long-held beliefs about these ancient felines.

Could chargrilled mushrooms be the key to fireproofing our homes? A team in Melbourne, Australia, unveiled a fire-resistant material created from the mycelium of edible mushrooms this week. With remarkable flame resistance and environmentally-friendly properties, the approach looks promising.

Finally, some intriguing space discoveries, including the Janus star, with its unique hydrogen-helium split surface, a giant exoplanet called PDS 70b, which reveals a potential sibling forming in its orbit, marking the first time two planets have been found to share an orbit, and the LEGO robot creating DNA machines.

Hosts Timothy Revell and Christie Taylor discuss all of this with guests Clare Wilkins, Corryn Wetzel and Alex Wilkins. To read about these subjects and much more, you can subscribe to New Scientist magazine at newscientist.com.
