Tim Leighton talks about his paper in Proceedings A in which they use nonlinear mathematical functions to process the echoes of dolphin-like pulses from targets immersed in bubble clouds successfully distinguishing the targets from the bubble clutter.

In celebration of Alan Turing's centenary, the Royal Society has published two special issues "The foundations of computation, physics and mentality: the Turing legacy" by S Barry Cooper and Samson Abramsky and "Computability and the Turing centenary" Organized by S. Barry Cooper and Philip Maini. Here we talk to Samson Abramsky about the richness of Alan Turing's intellectual legacy in the modern conception of computation.

Philosophical Transactions B has published a theme issue on "The social network and communicative complexity in animals" which addresses the hypothesis that an important factor influencing the complexity of communicative signals in individuals is the complexity of the social groups of which those individuals are members.

Metacognition can be defined as thinking about thinking and Philosophical Transactions B has just published an issue highlighting the advances being made in research to measure and quantify metacognition, and understand its neural basis. In this podcast guest editors Steven Fleming and Chris Frith discuss what metacognition is.

Most cases of colorectal cancer are linked to mutational inactivation of the Adenomatous polyposis coli (APC) tumour suppressor. In this podcast Mariann Bienz discusses her Open Biology paper 'The Adenomatous polyposis coli tumour suppressor is essential for Axin complex assembly and function and opposes Axin's interaction with Dishevelled' and the role APC plays in the development of colorectal cancer.

In this podcast Paul Barrett and Andrew Smith talk about a Special Feature in Biology letters they have guest-edited which brings together a series of papers that showcase how modelling the past is being applied to advance our understanding across a wide spectrum of current palaeontological endeavours.

The Large Hadron Collider (LHC) is opening the way for the search for new phenomena. The Philosophical Transactions A issue "Physics at the High Energy Frontier - The Large Hadron Collider Project" brings together papers from a discussion meeting that review the present state of knowledge of particle physics and the early results from the experiments at the LHC.

The brood parasitic behaviour of the commoon cuckoo is well known, with observations by Edward Jenner back in the 1780s having been publishing in Philosophical Transactions. The African greater honeyguide chick exhibits rather more brutal adaptations to kill its host siblings and the first detailed observations of this behaviour have been documented in a Biology Letters paper by Claire Spottiswoode and Jeroen Koorevaar.

Philosophical Transactions A has published a theme issue The Complexity of Sleep, which looks at the application of complexity science to studying the complex dynamics of the sleeping brain is a fast. Claire Birch talks to one of the Guest Editors, Thomas Wennekers, about the work presented in this issue.

The Royal Society has launched a new journal, Open Biology, which is a fast, open access journal covering biology at the molecular and cellular level. This selective, online journal will publish original, high-quality, peer- reviewed research articles. In this video, the Editor-in-Chief, Professor David Glover, talks about his visions for the journal.
