The Rutland ‘Sea Dragon’, An Astronomer's Christmas and some Animal Magic

After 20 years of planning, preparation and a nail-biting build up fraught by delays The James Webb Space telescope finally launched on Christmas day 2021. Anxious astronomers across the globe looked on as the JWST then completed even riskier manoeuvres to unfurl the 18 hexagonal components that make up its 6.5 meter diameter primary mirror. Cosmologist Dr Sheona Urquhart from the Open University tells us about the astronomical community’s tense Christmas day. Fresh from a TV spot on BBC Two’s Digging for Britain this week, Dr Dean Lomax and PhD candidate Emily Swaby share their excitement unearthing Rutland’s ‘Sea Dragon’ and explore what this find could tell us about Ichthyosaurs. At over 10 meters long this ancient ocean predator is the largest complete fossil of its kind to be discovered in the UK. Ichthyosaurs are commonly associated with Dorset and Yorkshire coastlines where fossils are often revealed as surrounding rock is eroded by the elements. Finding an ichthyosaur fossil inland is unusual but not unexpected as the higher sea levels 200 million years ago would put the east midlands underwater. And whilst the palaeontologists have been struggling through the Jurassic mud, cognition researchers at the University of Cambridge have been wowing their birds with magic tricks. Professor Nicky Clayton FRS, Professor of Comparative Cognition, explains what we can learn about the way jays think by assessing their reaction to different sleight-of-hand tricks. Corvids, the family to which these feathered friends belong, have long interested researchers due to their impressive cognitive abilities and Nicky’s team has shown that their Jays are not fooled by all of the same mis-directions as we are, but are fooled by some. And it could be down to not being able to tell the difference between a finger and a feather.Presented by Marnie Chesterton Produced by Alex Mansfield Assistant Producer Emily BirdMade in association with The Open University99% of users are being tracked by the algorithm.If you are part of the 1% who demands pure, untracked intelligence, you just found the bypass.
