Un equipo de científicos está explorando una fuente inusual de electricidad: tomates dañados que no son aptos para la venta en el supermercado. Su proyecto piloto consiste en una pila de combustible biológico que utiliza residuos de tomate sobrante de las cosechas en Florida.

A team of scientists is exploring an unusual source of electricity -- damaged tomatoes that are unsuitable for sale at the grocery store. Their pilot project involves a biological-based fuel cell that uses tomato waste left over from harvests in Florida.

Rising temperatures worldwide are changing not only weather systems, but - just as importantly - the distribution of water around the globe, according to a study published today (March 14, 2016) in the journal, "Scientific Reports."

Analysis of more than 40 years of water samples archived at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire tells a vivid tale of how the sources of precipitation have changed. Over the years, there has been a dramatic increase, especially during the winter, of the amount of water that originated far to the north.

Una simple, pero super-absorbente esponja artificial podría reducir el costo de limpieza de derrames de crudo en los países en desarrollo.

Un equipo de investigadores, con sede en el Instituto Italiano de Tecnología de Génova, encontró que las esponjas simples hechas de espuma de poliuretano absorbieron los derrames de petróleo mejor que las esponjas más caras tratadas con nanopartículas.

Two unexpected and shocking events have left heads swimming about the fate of President Obama’s signature initiative on climate change, the Clean Power Plan, which aims to replace many coal-fired power plants — the largest source of greenhouse gas emissions in the United States — with cleaner sources of energy.

Last Tuesday, the U.S. Supreme Court issued a stay on the Clean Power Plan until the litigation against it is finally resolved, suspending implementation of the plan for the foreseeable future. The vote was 5-4, along the customary ideological lines, and it led to great concern, bordering on quiet despair, among proponents of the plan. who now believed that the Supreme Court would ultimately strike it down. Opponents of the plan, including the coal industry, rejoiced.
 

The court’s order blocking Obama’s Clean Power Plan provides an opportunity for the U.S. to show other nations it has a flexible approach to cutting emissions, David Victor writes.
