Optical computer made from frozen light

Just how dark does it have to be before our eyes stop working? Research by a team from Rockefeller University and the Research Institute of Molecular Pathology in Austria has shown that humans can detect the presence of a ...

For years, scientists and engineers have synthesized materials at the nanoscale level to take advantage of their mechanical, optical, and energy properties, but efforts to scale these materials to larger sizes have resulted ...

Organic compounds in wastewater, such as dyes and pigments in industry effluents, are toxic or have lethal effect on aquatic living and humans. Increasing evidence has shown that the organic contaminants discharged from electroplating, ...

In a recent work published in Nature Communications, a research group led by ICREA Professor at ICFO Frank Koppens demonstrates a novel way to detect low-energy photons using vertical heterostructures made by stacking graphene ...

A technique developed by scientists at King Abdullah University of Science and Technology (KAUST), Saudi Arabia, has made more controlled fabrication of optoelectronic devices produced from a hybrid of organic and inorganic ...

A new MIT study could open up new areas of technology based on types of light emission that had been thought to be "forbidden," or at least so unlikely as to be practically unattainable. The new approach, the researchers ...

A couple of times in four billion years, evolution has slowed to a crawl. And an eon or so has passed before more complex life forms, such as simple animals, could arise.

Archaeologists at the Mayan ruin site of Palenque said Monday they have discovered an underground water tunnel built under the Temple of Inscriptions, which houses the tomb of an ancient ruler named Pakal.

(Phys.org)—A team of Brazilian astronomers, led by Denilso Camargo of the Federal University of Rio Grande do Sul in Porto Alegre, has discovered seven new embedded clusters located unusually far away from the Milky Way's ...

3-D movies immerse us in new worlds and allow us to see places and things in ways that we otherwise couldn't. But behind every 3-D experience is something that is uniformly despised: those goofy glasses.

Approximately one in 20 people will develop colorectal cancer in their lifetime, making it the third-most prevalent form of the disease in the U.S. In Europe, it is the second-most common form of cancer.

(Phys.org)—A pair of researchers at Cornell University has created an aluminum-based electrochemical cell that captures and sequesters carbon emissions while simultaneously generating a large amount of electricity. In their ...
