The brain is the CPU of our body. Despite being the world’s most complex computer, the brain is the basis of the enormous amount of behavioral research. Recently, neuroscientists at EPFL explored the mechanism behind ‘delayed motor response.’ Delayed-response paradigms are often used to study the neuronal circuits of sensorimotor transformation because they temporarily isolate…

To protect themselves from predators, some butterflies and moths also developed transparent wings. Because of their transparent wings, they are almost invisible to predators. What is the actual developmental basis of how they create their transparent wings? A…
