Erbium-doped fiber amplifiers (EDFAs) are devices that can provide gain to the optical signal power in optical fibers. They are often used in long-distance communication fiber optic cables and fiber-based lasers. Invented ...
A group of photonics researchers at Tampere University have introduced a novel method to control a light beam with another beam through a unique plasmonic metasurface in a linear medium at ultra-low power. This simple linear ...
Sparse data often make it difficult to track how climate change is affecting populations of insect species. A new study by the Technical University of Munich (TUM) and the German Centre for Integrative Biodiversity Research ...
Despite its below-freezing temperatures, the Arctic is warming twice as fast as the rest of the planet. As Arctic sea ice melts, fewer bright surfaces are available to reflect sunlight back into space. When fractures open ...
Programmed cell death is an important tool that an organism uses to keep itself healthy. When a cell does not function as it should, various stress reactions are activated. The goal of these reactions is to restore the original ...
Scientists at the University of Michigan Rogel Cancer Center were optimistic when they identified a small molecule that blocked a key pathway in brain tumors. But there was a problem: How to get the inhibitor through the ...
While the Voyager 1 spacecraft continues to return science data and otherwise operate as normal, the mission team is searching for the source of a system data issue.
Invasive species offer a rare research opportunity, as they often colonize new environments very different to their native habitat. One such species is the Jackson's three-horned chameleon (Triocerus j. xantholophus), which ...
Scientists at St. Jude Children's Research Hospital and Columbia University/New York State Psychiatric Institute are studying G protein-coupled receptors (GPCRs), membrane proteins that are the target of one-third of approved ...
Plants have been the primary source of our food for ages. With the human population growing rapidly, there is a continual increase in the demand for food produce. Since agricultural land is limited, fulfilling this increasing ...
