El sesenta por ciento de los estadounidenses viven en regiones donde los vehículos eléctricos (EVs) producen menos emisiones de carbono por milla que los híbridos más eficientes, de acuerdo con un análisis actualizado de la Unión de Científicos Preocupados (UCS). En 2012, esa cifra fue de apenas el 45 por ciento. "Los vehículos eléctricos están haciendo cada vez más para cumplir con su promesa tecnológica", dijo Don Anair, director de investigación del programa de vehículos limpios de la UCS. "Si queremos reducir la contaminación del transporte y el uso de petróleo, una gran parte de la solución es...

En una gran victoria para los tiburones y sus defensores, la Agencia de Protección Ambiental de Australia (EPA) ha recomendado que Australia Occidental (WA) ponga fin a su programa controversial de matanza de tiburones. Después de una serie de ataques mortales, el gobierno de WA propuso un nuevo programa en un esfuerzo por mantener seguros a los visitantes de las playas, lo cual implicó el establecimiento de líneas de batería con cebo que consisten en un anzuelo grande conectado a una boya y un ancla para mantenerlo en su lugar, en las zonas designadas a lo largo de las playas más conocidas, con la intención de...

From big company agricultural farming, to communal farming or even personal agronomy, the business of growing crops for an expanding global population will be crucial in the near future. The two most important resources needed to run these farms are one, water, and two, land. But these resources often come at a premium, especially with growing populations and increased food demand. Farmers and researchers have already started leaning towards genetic engineering and industrial processing to help with their crop yields, but a new solution in agribusiness is emerging. Vertical farming.

Depictions of animals in ancient Egyptian artefacts have helped scientists assemble a detailed record of the large mammals that lived in the Nile Valley over the past 6,000 years. A new analysis of this record shows that species extinctions, probably caused by a drying climate and growing human population in the region, have made the ecosystem progressively less stable. The study, published in Proceedings of the National Academy of Sciences (PNAS), found that local extinctions of mammal species led to a steady decline in the stability of the animal communities in the Nile Valley.

The fall foliage season that prompts millions of Americans to undertake jaunts into the countryside each year could come much later and possibly last a little longer within a century, according to new research. Climate change could postpone fall leaf peeping in some areas of the United States as summer temperatures linger later into the year, Princeton University researchers report in the journal Global Ecology and Biogeography.

The prime cod fishing grounds of North America have been depleted or wiped out by overfishing and poor management. But in Arctic waters, Norway and Russia are working cooperatively to sustain a highly productive — and profitable - northern cod fishery. What years of dwelling in the cold Atlantic had amassed, an army of knife-wielding, white-suited Norwegian factory workers were taking apart in just minutes. In a consummate display of optimization, streams of fish parts were whisked along on conveyor belts around and above me, with various cuts destined for their most appropriate markets. Nothing was wasted.
