Domestic cats introduced from the Near East and wildcats native to Europe did not mix until the 1960s, despite being exposed to each other for 2,000 years, according to two research papers published today in Current Biology.

Air pollution impairs successful mating of flies
Most insect pheromones are odor molecules containing carbon-carbon double bonds. Such double bonds are known to be easily destroyed by ozone.
When bugs swipe left
Vinegar flies use pheromones to ensure that they court and mate with members of the same species. As new fly species split off from a common ancestor, but continue to share the same environment, they need a way to rapidly diversify their pheromones to suppress inter-species mating. New research identifies a link between the genetic instructions for the production and perception of sex pheromones.
It’s Not the Heat, It’s the Humidity: Water Loss Hurts Bees Most in the Desert
Digger bees lose large amounts of water during flight, which compromises their activity period and survival in the desert heat. Researchers from Arizona State University will present their work this week at the American Physiological Society (APS) Intersociety Meeting in Comparative Physiology: From Organism to Omics in an Uncertain World conference in San Diego.
