Phys.org / New contactless method reveals how mirror-image materials respond differently to light
New research introduces a contactless way to see how mirror-image materials respond differently to circularly polarized light, without first building them into a complete electronic device. The researchers developed a novel ...
Phys.org / Traditional plastic forks shed harmful microplastics. Plastic created from sugar is an alternative
At a Massachusetts lab, pebble-sized pellets are transformed into forks and films that won't leave persistent microplastics in the environment.
Phys.org / What it's like to discover an ancient Egyptian tomb, and the race against time to preserve it
Looking inside a newly discovered ancient tomb for the first time is both exciting and terrifying. I was fortunate to experience this recently as director of an international research team carrying out fieldwork in the Theban ...
Tech Xplore / Three holographic layers steer red, green and blue light for brighter AR displays
Researchers have developed a full-color near-eye display that uses three stacked holographic gratings, each engineered to direct red, green or blue light. The new design could help advance compact, energy-efficient augmented ...
Phys.org / New species of mountain horned dragon identified in Thailand's high-altitude forests
Scientists have described a new species of lizard from the high mountain forests of western Thailand and have given it a name straight out of an American fantasy drama television series: Acanthosaura syrax, named after Syrax, ...
Medical Xpress / Why children often eat less in hot weather—and when parents should worry
If your child suddenly starts picking at meals during a spell of hot weather, it can be unsettling. But a smaller appetite for a few days can be a normal response to heat, particularly if your child is drinking well, has ...
Phys.org / Engineered enzymes forge carbon-carbon and carbon-nitrogen bonds with high selectivity
Researchers from the Manchester Institute of Biotechnology, including Dr. Zachary Birch-Price and professor Anthony Green, have developed a new family of engineered enzymes that can create several different types of chemical ...
Phys.org / Tiny particles defy action-reaction symmetry to stay in motion
From schools of fish and flocks of birds to microscopic synthetic particles, many systems in nature and the laboratory consist of individual units or agents that move by consuming energy. These systems are known as active ...
Phys.org / More than a decade of observation in Seattle suburbs shows where sensitive bird species won't go
Nearly 30 years ago, a simple question sent University of Washington researchers into the Puget Sound lowlands to look for birds. With Seattle's population swelling and housing developments pushing into once-forested suburbs, ...
Phys.org / Can better civics education restore voter dissatisfaction over political corruption?
This summer, America celebrated the 250th anniversary of the signing of the Declaration of Independence, widely recognized as the formal founding of our nation and one of the early stages of establishing a democratic government.
Phys.org / Scientists uncover a hidden mechanism that drives RNA synthesis
Scientists have long been fascinated by two promising classes of antibiotics that disable RNA polymerase (RNAP). They knew that these drugs could grind gene expression to a halt in several pathogens, including the bacterium ...
Phys.org / Three days of Ontario wildfire smoke brought unhealthy air to 106 million person-days
Smoke from Canada's July wildfires exposed people across Canada and the United States to unhealthy, very unhealthy or hazardous air for nearly 106 million person-days between July 15–17. Over the peak impact period of July ...
