Many technologies have become so advanced that they've been miniaturized to take up less space and weigh less. That's what happened to detector controls and data conversion electronics on the James Webb Space Telescope being built by Northrop Grumman. The electronics will convert analog signals to digital signals and provide better images to Earth.
Night-time noise from aircraft or traffic can increase a person's blood pressure even if it does not wake them. Scientists monitored 140 sleeping volunteers in their homes near London Heathrow and three other major European airports. The researchers measured the volunteers' blood pressure remotely at 15-minute intervals and then analyzed how this related to the noise recorded in the volunteers' bedrooms.
