Many beetles have defense mechanisms which involves foul chemicals squirting from their abdomens, but bombardier beetles have taken it to the next level. Researchers from MIT, the University of Arizona, and Brookhaven National Laboratory wanted to see how it works, so they studied the bombardier beetle and figured it out. The research is published in Science.
The rate of global warming varies from year to year, and climate change deniers try to take advantage of this and argue that global warming is actually slowing down. That may or may not be true, but Earth is still on course for extremely dangerous levels of warming, and, as yet another study has concluded, this is also causing extreme weather.
