The Chinese immigrant-built Donner Summit tunnels consist of numerous tunnels that dot the trail of the Transcontinental Railroad. But despite their historical significance in connecting the country, helping to shrink the time taken to travel from the East Coast to the West Coast from 118 days to six days, the tunnels have been left by the wayside. Remaining on private property, they have never officially been recognized, leaving them with no active supervision; fate has instead deemed the tunnels to a life of graffiti and vandalism.

‘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.
