The idea that water freezes faster when it's warmer is popular thanks to experiments in the 1950s. Now, Imperial researchers have finally proven it to be incorrect - so why did it take so long to disprove such a counterintuitive theory?

The World Economic Forum has convened Global Future Councils to help it define the fourth industrial revolution. Dr Diego Oyarzun, one of Imperial's representatives, joined the council for the future of biotechnologies this year.

Imperial researchers were out in force at the annual climate conference, where scientists from around the world discussed how to move forward with the agreement from Paris last year.

Physics gets weird as scientists propose making buildings 'invisible' to earthquake waves and pose a theory that Einstein has it wrong about the speed of light. Plus the world's first cloned mammal is celebrated with an unusual sculpture.

Post-operative delirium can leave people confused and distressed after major surgery. One patient talks us through his experience and we discuss the results of a trial at Imperial that could help solve the problem - by using sedatives.

November's Fringe-goers investigated the evidence at the intersection of science and crime, including the chemistry of fingerprints, detecting white collar crime and the sociology of stabbings.

New Imperial College Research Fellow Dr Tom Haworth tells us how he's investigating the earliest stages of planets and stars, and the results he's found just one month into his time at Imperial.

New diesel engines have been found to breach emissions limits when tested on the road as opposed to the lab, and physicists make it possible to 3D print a map of the earliest light in the universe.
