There is some correlation between naturally deep voices and men’s health that could explain why men with deeper voices are perceived as healthier by many people. A deeper voice is caused by the presence of more testosterone in the body. Testosterone is posited to take away energy from the immune system, so only men not under stress and in peak physical condition can afford to develop more testosterone-dependent traits like deeper voices and bigger bodies.

‘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.
