A surprise unearthing of fossils could fill a gap in the paleontological record; an extraordinary discovery about the properties of insect wings; and Catalyst celebrates science with the Australian Museum's Eureka Prizes. FOSSILS EXPOSEDA surprise unearthing of fossils beneath a Brisbane building site could fill a gap in the paleontological record, and explain how life continued after the dinosaurs. This treasure trove of fossils, believed to be around 55 million years old, holds evidence of the existence of ancient crocodiles, fish, shells and plants. The find is remarkable because these creatures lived after the dinosaurs were wiped out, but before Australia's mega fauna emerged. Called the 'paleontological dark ages' not much is known about the flora and fauna during this time. Mark Horstman investigates.WINGS OF WONDERIf you need your hip or knee joint replaced, a titanium implant is a common choice among surgeons. They're light, durable and strong, and they are readily accepted by the human body. Unfortunately bacteria love the surface of titanium too and despite the most stringent sterilisation procedures, some surgeries result in deadly infection. How to make titanium resistant to bacteria is a puzzle that has been keeping researchers occupied for years. Anja Taylor reports on an extraordinary discovery about the physical properties of insect wings that could offer new hope for a medical surface that can literally shred bacteria.
