Financial economist Dirk Baur argues that it’s both environmentally and economically unviable to mine gold despite its increasing value. For a resource that’s expensive to extract and taxing on the environment and the surrounding communities, there’s little payoff as most gold ends up inside bank vaults and investment companies. If investors will be buying gold they’ll never see, then Baur offers an alternative: “green gold”, or underground gold identified by mining companies that will remain unmined. 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.
