A dangerous bacterial disease has pet owners everywhere worried about the safety of their animals. Potentially deadly to both humans and canines, Leptospirosis is found across the country.

Quick DNA Tests Crack Medical Mysteries Otherwise Missed. Doctors used a rapid DNA test to identify a Wisconsin teen's unusual infection with Leptospira bacteria (yellow), which are common in the tropics.

This sprinkle of cosmic glitter is a blue compact dwarf galaxy known as Markarian 209. Galaxies of this type are blue-hued, compact in size, gas-rich, and low in heavy elements. They are often used by astronomers to study star formation, as their conditions are similar to those thought to exist in the early Universe. This image captures it undergoing a particularly dramatic burst of star formation, visible as the lighter blue cloudy region towards the top right of the galaxy.
