This week, new research number crunching millions of bits of data on breast cancer has allowed scientists to reclassify the disease into 10 different subtypes. They say this is a huge break though which will lead to new treatments and improve outcomes for women with the disease. The lead author of the Cancer Research UK study Carlos Caldas explains its impact.

The maths of politics. Stand up Mathematician Matt Parker and professor of theoretical physics Andrea Rapisarda look at the role mathematics plays in elections and the way politicians behave. Andrea argues political decisions would be improved if politicians were selected at random rather than elected, but Matt sees the mathematical flaw in electoral systems, which he likens to rolling a dice – one where the voters hardly ever get the outcome they wish for.

Its 40 years since British scientist Godfrey Hounsfield invented the CT scan. This multilayered use of x ray imagery has revolutionised the diagnosis of internal health problems and is used worldwide. We speak to Liz Beckmann, one of Godfrey Hounsfield’s former colleagues and the co author of a new book on his life and work, out this week; 'Godfrey Hounsfield: Intuitive Genius of CT'

And we continue our experiments for 'So You Want To Be A Scientist'...

    The Science of Stripes

    ‘So You Want to Be a Scientist?’ finalist Val Watham is at the Edinburgh Science Festival. Together with her mentor, Dr Peter Thompson from the University of York, she’s putting their stripey clothes experiment to the test.

    Are horizontal or vertical stripes more flattering? We join them as they gather data from over 500 visitors who are watching and rating videos of people wearing stripey clothes.

    Next, Val and Peter have the daunting task of analysing the enormous spreadsheet of data they have collected, before revealing the results in June.
