Lasers etch a 'perfect' solar energy absorber

The University of Rochester research lab that recently used lasers to create unsinkable metallic structures has now demonstrated how the same technology could be used to create highly efficient solar power generators.

Dozens potentially exposed to toxic mercury in Houston spill

Dozens of people in Houston potentially were exposed to the toxic metal mercury after it was spilled outside a Walmart, a Sonic Drive-In and a gas station, officials said. Federal and local investigators were trying to determine ...

New York takes aim at skyscrapers' sky-high energy usage

It's a tall order indeed: How do you make aging, energy-hungry skyscrapers more efficient and less polluting? The city of New York, the historic capital of the skyscraper, is determined to do so by requiring the enormous ...

Scientists discover what powers celestial phenomenon STEVE

The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic electrons like those that power the aurora, according to new research. In a new study, ...

New X-ray measurement approach could improve CT scanners

A new measurement approach proposed by scientists at the National Institute of Standards and Technology (NIST) could lead to a better way to calibrate computed tomography (CT) scanners, potentially streamlining patient treatment ...

New study reveals when a superconductor truly becomes super

Unraveling the mystery of superconductivity at high temperatures, specifically in copper oxide materials, remains one of the most puzzling challenges in modern solid-state physics. But an international research team of engineers ...
