Discovery advances understanding of theory of relativity and quantum. A major hurdle for work at the forefront of fundamental physics is the inability to test cutting-edge theories in a laboratory setting. But a recent discovery opens the door for scientists to see ideas in action that were previously only understood in theory or represented in science fiction.

One such theory is on the Unruh effect. When astronauts in a spacecraft undergo super strong acceleration and see the light of stars stream by, then the Unruh effect is an additional warm glow on top of the streaming light. First predicted by Canadian physicist Bill Unruh, this effect is closely related to the glow from black holes predicted by Stephen Hawking...

Imagine being able to measure your blood sugar levels, know if you’ve had too much to drink, and track your muscle fatigue during a workout, all in one small device worn on your skin. Engineers at the University of California San Diego have developed a prototype of such a wearable that can continuously monitor several health stats — glucose, alcohol, and lactate levels — simultaneously in real-time.

The device is about the size of a stack of six quarters. It is applied to the skin through a Velcro-like patch of microneedles, that are each about one-fifth the width of a human hair...

Research could improve efficiency for storing renewable energy, making carbon-free fuels, and manufacturing sustainable materials. A team of energy researchers led by the University of Minnesota Twin Cities has invented a groundbreaking device that electronically converts one metal into behaving like another to use as a catalyst for speeding chemical reactions...
