Neil Levy argues that social media causes a loss in knowledge not only because of echo chambers but also because of our easy access to diverse opinions. Differing opinions and evidences contradictory to our beliefs cause us to doubt them, sometimes enough to discard them from our knowledge. Although not all of this evidence is true, the sheer volume of it available online makes it almost impossible to fact check easily. We’re left with doubts we can’t address completely, and so our knowledge is threatened. 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.
