Smart sleepwear: Introducing 'phyjama,' a physiological-sensing pajama

Posted: 12 Sep 2019 01:25 PM PDT

Scientists expect that in the future, electronically active garments containing unobtrusive, portable devices for monitoring heart rate and respiratory rhythm during sleep, for example, will prove clinically useful in health care. Now researchers have developed physiological-sensing textiles that can be woven or stitched into sleep garments they have dubbed 'phyjamas.'

Novel atomic clock design offers 'tweezer' control

Posted: 12 Sep 2019 11:18 AM PDT

Physicists have demonstrated a novel atomic clock design that combines near-continuous operation with strong signals and high stability, features not previously found together in a single type of next-generation atomic clock. The new clock, which uses laser 'tweezers' to trap, control and isolate the atoms, also offers unique possibilities for enhancing clock performance using the tricks of quantum physics.

Elaborate Komodo dragon armor defends against other dragons

Posted: 12 Sep 2019 10:43 AM PDT

Just beneath their scales, Komodo dragons wear a suit of armor made of tiny bones. These bones cover the dragons from head to tail, creating a 'chain mail' that protects the giant predators. However, the armor raises a question: What does the world's largest lizard -- the dominant predator in its natural habitat -- need protection from?

A robot with a firm yet gentle grasp

Posted: 12 Sep 2019 09:48 AM PDT

Human hands are skilled at manipulating a range of objects. We can pick up an egg or a strawberry without smashing it. We can hammer a nail. One characteristic that allows us to perform a variety of tasks is the ability to alter the firmness of our grip, and researchers have developed a two-fingered robotic hand that shares this trait. The goal? Improving safety in industrial settings where robots work with people.

Why do birds migrate at night?

Researchers found migratory birds maximize how much light they get from their environment, so they can migrate even at night. 

Device generates light from the cold night sky
