Conforme Japón busca poner fin a la dependencia de la energía nuclear, una de las respuestas está flotando en las "islas solares", escribe Jon Major. Una isla solar de 70MW abrió el año pasado, y dos plantas adicionales han sido anunciadas. Dos empresas en Japón recientemente anunciaron que van a iniciar la construcción de dos grandes islas solares que flotarán en embalses. Esto sigue a la planta de energía del fabricante de teléfonos inteligentes de Kyocera, Kagoshima Nanatsujima, la más grande del país con 70 megavatios, que se inauguró a finales de 2013 y se encuentra...

Governments must shift subsidies and research funding from agro-industrial monoculture to small farmers using 'agroecological' methods, according to the UN's Special Rapporteur on the Right to Food. And as Nafeez Ahmed notes, her call coincides with a new agroecology initiative within the UN's Food and Agriculture Organisation. This is critical for future agricultural policies. Currently, most subsidies go to large agribusiness. This must change. Governments must support small farmers. Modern industrial agricultural methods can no longer feed the world, due to the impacts of overlapping environmental and ecological crises linked to land, water and resource availability.

Xanthohumol, a type of flavonoid found in hops and beer, has been shown in a new study to improve cognitive function in young mice, but not in older animals. The research was just published in Behavioral Brain Research by scientists from the Linus Pauling Institute and College of Veterinary Medicine at Oregon State University. It’s another step toward understanding, and ultimately reducing the degradation of memory that happens with age in many mammalian species, including humans.

El xantohumol, un tipo de flavonoide que se encuentra en el lúpulo y la cerveza, ha demostrado en un nuevo estudio que mejora la función cognitiva en los ratones jóvenes, pero no en los animales más viejos. La investigación acaba de ser publicada en Behavioral Brain Research por científicos del Instituto Linus Pauling y del Colegio de Medicina Veterinaria de la Universidad Estatal de Oregon. Es otro paso hacia...

Some scientists and analysts are touting carbon capture and storage as a necessary tool for avoiding catastrophic climate change. But critics of the technology regard it as simply another way of perpetuating a reliance on fossil fuels. For more than 40 years, companies have been drilling for carbon dioxide in southwestern Colorado. Time and geology had conspired to trap an enormous bubble of CO2 that drillers tapped, and a pipeline was built to carry the greenhouse gas all the way to the oil fields of west Texas. When scoured with the CO2, these aged wells gush forth more oil, and much of the CO2 stays permanently trapped in its new home underneath Texas.

Many native species have vanished from tropical islands because of human impact, but University of Florida scientists have discovered how fossils can be used to restore lost biodiversity. The key lies in organic materials found in fossil bones, which contain evidence for how ancient ecosystems functioned, according to a new study published in the September issue of the Journal of Herpetology.
