News: Biggest ever obesity study and renaming Imperial – Figures from nearly every country in the world reveal that for the first time there are more overweight than underweight people, and a campaign to rename Imperial College London.

SET for Britain – Two early career researchers from the Department of Bioengineering at Imperial talk about their experience presenting their work at an event at Parliament, including engaging with MPs, Lords and policymakers.

Real-time tubes – An undergraduate in the Department of Computing has also been hobnobbing with Lords at a luncheon where he received an award from the Worshipful Company of Information Technologists. He was honoured for his work on an app that makes better use of TfL data to give commuters real-time tube updates.

Atoms Family values – We examined things at the molecular level for the most recent Imperial Fringe event, including testing out next-generation fuel cells, designing solvents to extract carbon dioxide, and making clothing super water repellent.
