Thanks to a £35 million investment from Cancer Research UK’s Grand Challenge, Hannon’s and Bunch’s teams of scientists are forming international research collaborations to map tumours at a level of detail that has never previously been imaginable. Using cutting edge biology, chemistry and even astrophysics, they are tackling the challenge from two angles: Bunch is building a ‘Google Maps’ of cancer, whilst Professor Hannon’s use of virtual reality will allow scientists, doctors and patients to walk within tumours. These new perspectives could transform how we understand and treat all types of cancer. Cervantes-Watson is CRUK’s Director of Funding Innovation.
