Scientists have discovered a pheromone that locusts emit so as not to be devoured by their congeners. Find could be used in the future to tame these voracious beasts. Previous research showed that these swarms were partly governed by the threat of cannibalism. Methods to control their population could use technology that increases competition between them, warns Bill Hansson, lead author of the study, published in the journal Science. The discovery shed light on the "complicated balance" between the mechanisms that drive migratory locUSTs to cluster together, or compete.
The study demonstrates that the creation of groups is not necessarily a result of social behavior, but can also be accounted for by individuals’ entirely
n August, a mountain lion was sighted several times prowling the suburbs of New Canaan, Connecticut, and not for the first time. A decade ago, a young mountain lion made its way to Connecticut, prowling more than 1,500 miles from the Black Hills of South Dakota, before it was killed crossing a highway.
