Hungry, corn-loving caterpillars trick corn plants into thinking they are being attacked by a pathogen which buys them time to eat more and grow larger faster.
Land-sharing was found to be counterproductive for retaining biodiversity. A recent study suggests that leaving some land completely untouched, while increasing farming practice solely in other areas, will benefit the evolutionary diversity of bird species.
Corn spots, it seems, know the meaning of self-sacrifice. When under attack from a pathogen, these plants commit "cell suicide" to prevent any further damage, a new study describes, and scientists are just beginning to understand how this defense mechanism works.
