In August 2020, a Steller’s sea-eagle was spotted inland in Alaska, far from its home range of East Asia. In March 2021, another Steller’s sea-eagle was spotted all the way down in Texas — the furthest any of its kind had been found away from home. Bird watchers begun speculating if these birds were one and the same. It was all but confirmed when another sighting was reported in eastern Canada months later; high-quality pictures show that the eagle’s wing markings matched that of the bird spotted in Alaska.

‘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.
