Spider conversations decoded with the help of machine learning and contact microphones

Arachnids are born dancers. After millions of years of evolution, many species rely on fancy footwork to communicate everything from courtship rituals, to territorial disputes, to hunting strategies. Researchers usually observe these movements in lab settings using what are known as laser vibrometers. After aiming the tool’s light beam at a target, the vibrometer measures […]

This new subsea communications system can run on an iota of power

Researchers at MIT have designed a new underwater communication system that employs 70-year-old technology while also requiring one-millionth the energy needed for existing arrays. Not only that, but the team’s design allows for transmissions that can travel 15 times farther than current devices. “What started as a very exciting intellectual idea a few years ago—underwater communication […]
