Time reversal: A simple particle could reveal new physics

(PhysOrg.com) -- A simple atomic nucleus could reveal properties associated with the mysterious phenomenon known as time reversal and lead to an explanation for one of the greatest mysteries of physics: the imbalance of matter ...

Lazy ants make themselves useful in unexpected ways

If the first thing that comes to mind when you think about ants is "industrious," you might be in for a surprise. In 2015, biologists at the University of Arizona reported that a sizable chunk of the "workers" that make up ...

Researchers demonstrate a quantum advantage

Quantum computing and quantum sensing have the potential to be vastly more powerful than their classical counterparts. Not only could a fully realized quantum computer take just seconds to solve equations that would take ...

Better thermal-imaging lens from waste sulfur

Sulfur left over from refining fossil fuels can be transformed into cheap, lightweight, plastic lenses for infrared devices, including night-vision goggles, a University of Arizona-led international team has found.

Archaeologists uncover new clues to Maya collapse

Using the largest set of radiocarbon dates ever obtained from a single Maya site, archaeologists have developed a high-precision chronology that sheds new light on patterns leading up to the two major collapses of the ancient ...

Researchers track Chinese space station as it falls

A defunct Chinese space station, Tiangong-1, is expected to fall to Earth any day now—on March 31, give or take a few days. When it does, it will be the largest manmade object to re-enter Earth's atmosphere in a decade.

Three nearly Earth-size planets found orbiting nearby star

NASA's Kepler Space Telescope, despite being hobbled by the loss of critical guidance systems, has discovered a star with three planets only slightly larger than Earth. The outermost planet orbits in the "Goldilocks" zone, ...

Testing Einstein's E=mc2 in outer space

(Phys.org)—University of Arizona physicist Andrei Lebed has stirred the physics community with an intriguing idea yet to be tested experimentally: The world's most iconic equation, Albert Einstein's E=mc2, may be correct ...

Why we walk on our heels instead of our toes

James Webber took up barefoot running 12 years ago. He needed to find a new passion after deciding his planned career in computer-aided drafting wasn't a good fit. Eventually, his shoeless feet led him to the University of ...
