Spanning the entire country, Hungary’s National Blue Trail took off in 1952 after it “gamified” the trail by introducing its stamp collection system. Acting as a fantastic marketing program, the stamps, which were collected at various points along the trail, were proof that a hiker had traversed the area. But collecting stamps wasn’t easy; the stamps, being in such high demand, were often stolen from their vendors, challenging hikers to aid in their retrieval. 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.
