Emerald green is a gorgeous, vibrant shade of green that adorns the covers of many Victorian-era books. It’s also potentially lethal. Emerald green, also used in Victorian wallpapers, contains copper acetoarsenite, which is comprised partly of arsenic—a highly poisonous element. Many libraries unknowingly contain these lethal books, but they’re mostly safe if handled properly. Even bearing this in mind, all books that might have arsenic should be handled with gloves and kept safe until they can be tested. 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.
