A new study in PLOS Biology finds that bumblebees can learn to solve puzzles from each other — suggesting that even invertebrate animals may have a capacity for culture.
Scientists wanted to learn whether bees, like humans and other mammals, had any interest in playing for fun's sake. They say they have evidence that bees do, and that could change how we view insects.
Environmental writer Oliver Milman says habitat loss, pesticides and climate change are killing off insects worldwide, which, in turn, threatens humans. His new book is The Insect Crisis.
