We discuss the creation of a new bio-solar panel developed by Imperial researchers which involves printing light energy-capturing bacteria and circuitry directly on to paper; plus we mark the 125th birthday of the Queen’s Tower.

In this edition: We discover Imperial's involvement in the IPCC, meet underfloor robots and explore the Imperial universe at the latest Fringe.

We discuss a huge study revealing a tenfold increase in child and adolescent obesity worldwide, a small trial using magic mushrooms to treat depression and finally uncovering the causes of trench foot.

We talk to Professor Jim Skea, an Imperial academic who co-chairs one of the Intergovernmental Panel on Climate Change's Working Groups, about how his two worlds overlap.

We visit the factory where Q-bots are being built - helpful robots that get into crevices under floorboards and spray insulation, making old homes more energy efficient.

Fringe season is back! We commemorate the demise of Cassini with Imperial researchers investigating all things space.

Professor Jim Skea, from the Centre for Environmental Policy, is Vice-Chair for one of the IPCC's Working Groups. Here he describes what Working Group III does, how the IPCC stays relevant, and how people can get involved.

We meet Imperial participants in the World Economic Forum's Young Scientists community, preparing to share their research with world leaders and the general public.
