It's no secret that the amount and quality of restful sleep has a significant impact on our day-to-day well-being and long-term health. Unlike devices that merely monitor and report sleeping data, such as the Sleepace RestOn, the nuyu Sleep System takes a more active approach under the covers, by automatically changing bed temperature through the night.
While some electric cars may have a decent range in places like
California, they're not so impressive in locations with frigid winters.
That's because their battery is powering not only the motor, but also
the cabin heating system. Now, however, engineers at Germany's
Fraunhofer Institute for Manufacturing Engineering and Automation are
developing new technology that could keep EV drivers warm, without leaving them stranded.
In an effort to improve the energy efficiency of building, researchers have sought to develop windows that change transparency to let more light – and therefore heat – through when it's cold, and less when it's hot. Unfortunately, these methods tend to impede the passage of visible light, some by tinting panes and others by complete obscuration. But a team at the Cockrell School of Engineering at The University of Texas at Austin has developed a "smart window" technology that allows the passage of visible light while blocking heat, or vice versa.
In order to treat injured joints, patients are often advised to apply
heat. This typically takes the form of a hot water bottle or
microwavable hot pack (which are cumbersome and cool off) or a heating
pad (which needs to be plugged in). Now, however, scientists from Korea
and the US have created a battery-powered thin mesh that applies heat
and stays put.
