A new smartwatch developed at the University of California, Los Angeles has the potential to finally make cortisol a useful measure of personal health by tracking it. Cortisol is a hormone produced by the body in response to stress. The problem with measuring cortisol is that a single measurement is relatively useless because some people already have heightened levels of the hormone due to psychiatric disorders. However, continuously tracking cortisol levels makes it more useful because doctors can detect spikes in cortisol that might be indicative of disease. 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.
