Scientists are buzzing about new research that shows bumblebees can understand time. In a study, researchers found that bees can determine the duration of a light flash. They used a brief flash of light to lure the bees to fly toward something sweet. Researchers say the bees were able to repeat this even when no food was available. They say this proves they can remember timing and are capable of learning. This is the first time researchers have demonstrated that insects perceive time like humans
