Supercomputers and genetic engineering could help boost crops’ ability to convert sunlight into energy and tackle looming food shortages, according to a team of researchers. Photosynthesis is far from its theoretical maximum efficiency, say the authors of a paper in Cell, published on 26 March. They say that supercomputing advances could allow scientists to model every stage in the process and identify bottlenecks in improving plant growth.
Investigadores en salud pública de la escuela Johns Hopkins Bloomberg dicen que los niveles de radón en los hogares de Pennsylvania han ido en aumento desde 2004, donde el 42% de las lecturas supera lo que el gobierno de Estados Unidos considera seguro, más o menos desde la época en que la industria del fracking comenzó a perforar pozos de gas natural en el estado.

Johns Hopkins Bloomberg School of Public Health researchers say that levels of radon in Pennsylvania homes - where 42 percent of readings surpass what the U.S. government considers safe - have been on the rise since 2004, around the time that the fracking industry began drilling natural gas wells in the state.
The researchers, publishing online April 9 in Environmental Health Perspectives, also found that buildings located in the counties where natural gas is most actively being extracted out of Marcellus shale have in the past decade seen significantly higher readings of radon compared with buildings in low-activity areas. There were no such county differences prior to 2004. Radon, an odorless radioactive gas, is considered the second-leading cause of lung cancer in the world after smoking.
Monarch caterpillars are vulnerable to neonicotinoid toxicity at concentrations as low as 1 part per billion, writes Jonathan Latham, and that makes them vulnerable to residues from commercial crops - and even more so from horticultural use in plant nurseries!
Se estima que en 2014 más de dos mil millones de teléfonos móviles fueron vendidos en todo el mundo. De ellos, más de mil millones se estima que eran teléfonos inteligentes. Asimismo, se estima que un masivo 87% de la población del mundo ahora utiliza teléfonos móviles. Estas son cifras impresionantes, pero ¿cuántos de nosotros hemos pensado de donde nuestros preciosos teléfonos móviles vienen y que les sucede una vez que los descartamos por un modelo más nuevo?
Cada año millones de teléfonos móviles se producen en el mundo y un número igual se desecha.
The U.S. energy portfolio changes over time. Scientific and technologic advances related to hydraulic fracturing have dramatically increased the supply of U.S. oil and gas; because of this, a methane economy - in which natural gas provides the leading share of primary energy consumption - is now a possible scenario for U.S. energy development. In a report released by the American Geosciences Institute (AGI), the social, political, technical and environmental components of a methane economy are identified. The report also addresses how industry, government and the public might best work together to advance common energy goals.
