Magnetars are objects that have the strongest magnetic fields known in the universe, with an average of 1013 to 1015 Gauss. For comparison, the magnetic field at the Earth’s surface ranges from 0.25 to 0.65 gauss. One hypothesis for the formation is that a magnetar is a neutron star whose former star already had a sufficiently expressive magnetic field which could have been greatly intensified during the supernova explosion and subsequent gravitational collapse that gave rise to [...]

Brazil has not had cases of urban yellow fever since 1942, but the wild version can, by chance, infect people who live near, or frequented, forests and jungles.
