Bending light for safer driving; invisibility cloaks to come?
Optical cloaking allows objects to be hidden in plain sight or to become invisible by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, like in the "Harry Potter" books, researchers in recent years.....»»
Rolling with the punches: How mantis shrimp defend against high-speed strikes
Mantis shrimp are small creatures known for their superlatives. Their eyes have 12 to 16 different color receptors versus our own three, and can detect the polarization of light. Their punches are famously fast, accelerating on par with a 22-caliber.....»»
