A/B tests are an important part of many businesses’ digital presence. Like randomised control trials, they test hypotheses by presenting two versions of a web page where everything is identical save for one detail. It aims to establish which features are better for business, trying to find a causal relationship between implemented features and customer retention. For example, Google conducted 40 A/B tests before settling on a link colour that drew people’s attention and made them more appealing to click on. Read full article here

‘Ghostly’ neutrinos provide new path to study protons
In groundbreaking research, an international collaboration of scientists from the University of Rochester have used a beam of neutrinos to measure the size and shape of the protons that make up the nuclei of atoms. This feat, once thought impossible, provides scientists with a new way of looking at the small components of an atom’s nucleus and opens up a wealth of new information about the structure of an atom’s nucleus and the dynamics of the forces that affect neutrino interactions. The researchers solved the challenge of harnessing neutrinos in large numbers by using a neutrino detector containing a target of both hydrogen and carbon atoms, and over nine years of data collection at Fermilab’s accelerator.
