Dragonfly's Metabolic Disease Provides Clues about Human Obesity
Penn State researchers studied the dragonfly, Libellula pulchella, and discovered that a supposedly harmless parasite triggers metabolic disorders similar to those found in humans afflicted with insulin resistance, type 2 diabetes, and obesity. Credit: Ruud Schilder

Earth-Like Planets May Be Common in Known Planetary Systems
This image shows the differences (not to scale) between the inner regions of our Solar system, and a simulated planetary system containing a "hot Jupiter".
Planet or a Failed Star? . . . Discovery Reveals One of the Smallest Stellar Companions Ever Seen
This NASA Hubble Space Telescope image shows one of the smallest objects ever seen around a normal star. Astronomers believe the object is a brown dwarf because it is 12 times more massive than Jupiter. The brown dwarf candidate, called CHXR 73 B, is the bright spot at lower right. It orbits a red dwarf star, dubbed CHXR 73, which is a third less massive than the Sun. At 2 million years old, the star is very young when compared with our middle-aged 4.6-billion-year-old Sun.
