“Predator” bacteria (green) surround “prey” bacteria (red) in this petri dish version of the Serengeti. Rather than eating their prey, however, predator cells release a chemical that activates a suicide gene in the prey. Prey cells also release a chemical, but one that promotes survival of the p...

From fungi to flies, some parasitic species have figured out how to control their host's behavior to get what they need. See what happens when bugs go really bad with this slide show from Scientific American. Read More
Saturn’s moon Titan is wrapped in a thick, hazy atmosphere whose chemistry may mirror conditions on Earth before life emerged here some 4 billion years ago. In October Sarah Hörst reported that the resemblance is more than superficial. She simulated Titan’s haze in the lab and found it naturally... Read More
