September 28 is World Rabies Day, timed to the death of Louis Pasteur, the scientist whose vaccine the observance exists to honour. It's also the anniversary of one of Hyderabad's deadliest natural disasters, and of the day NASA said modern Mars still has flowing water.

Did you know
Pasteur's rabies vaccine had never been tried on a person until July 1885, when he used it — against medical convention, since he wasn't a physician — on a nine-year-old boy bitten fourteen times by a rabid dog. The boy survived and became the first person ever vaccinated against rabies.
