The robot pauses at the edge of the room as an engineer checks its sensors. Then, with a soft mechanical hum, this humanoid machine begins to move. It lifts a mannequin from a bed, slowly and carefully. The engineers hold their breath.

I am in a robotics lab in Tokyo, Japan, as part of my Wellcome research fellowship. The engineers have repeated this test hundreds of times…The Conversation (Full Story)

Four humans recently looped around the Moon. Their vessel, an Artemis capsule, was a thin metal shell whose life-support system kept them alive: it provided a carefully balanced atmosphere, a closed water loop, a finite supply of food and a means for disposing human waste. The life support was not optional. It was a necessity.

Consider this: not once in the history of human spaceflight has an astronaut been known to tamper with their life support system. No one has ever decided to vent some oxygen for fun. No one has argued for a personal right to increase their CO₂The Conversation (Full Story)

Annual medical checkups typically cover the basics: diet, exercise and mental state. Surprisingly, many primary care providers fail to ask about one of the fundamental contributors to well-being: sleep.

We are two neuroscientists who study sleep and memory. We have both experienced this omission with our own doctors, even though we represent different ages and genders.…The Conversation (Full Story)
