The Brazilian Judiciary determined to reduce the level of electromagnetic pollution generated by power lines to standard adopted by Swiss law (1.0 microtesla).
Two associations of residents in São Paulo – the largest city of Brazil – proposed the action. The plaintiff has pleaded to not be exposed to electromagnetic fields incompatible with the human health.
The electromagnetic fields generated by power lines that cross these areas is 10 times greater than the level determined by the court. The judgment of the Court of State of São Paulo (Tribunal de Justiça de São Paulo) has determined that the concessionaire of electric power reduces the electromagnetic field generated by power lines that pass through these neighborhoods.

The world's stronghold for Indian rhinos—the state of Assam—has seen its population leap by 27 percent since 2006, despite a worsening epidemic of poaching that has also seen 156 rhinos killed during the same period. According to a new white paper, the population of Indian rhinos in Assam hit 2,544 this year up from a nadir of around 200 animals in the early 1900s.

While one may think that forest and lake ecosystems are two separate networks, new research shows how forest debris is an important contributor to freshwater food chains. How? Debris in the form of organic carbon from trees washes into freshwater lakes, which consequently supplements the diets of microscopic zooplankton and the fish that feed on them. Researchers at the University of Cambridge conducted a study at Daisy Lake in Ontario, Canadian by observing Yellow Perch fish from different parts of the water body with varying degrees of surrounding forest cover. Carbon from forest debris has a different elemental mass than carbon produced by algae in the aquatic food chain. By analyzing the young Perch that had been born that year, scientists were able to determine that at least 34% of the fish biomass comes from vegetation, increasing to 66% in areas surrounded by rich forest. Essentially, the more forest around the edge of the lake, the fatter the fish in that part of the lake were. Similarly, the sparser the forest leaves, the smaller the fish.

With summer temperatures fast approaching, households across the country are installing and prepping air conditioning units in anticipation of hot, sticky weather. However, a potentially brutal cycle may be in store if summertime extreme-heat days are projected to become more frequent and intense as a result of climate change. According to a new study conducted in Phoenix by Arizona State University researchers, so much wasted heat is emitted by air conditioning units that it actually raises the city's outdoor temperature at night by 1-2.7 degrees! Consequently, these warmer temperatures may encourage individuals to further their demands and energy use of their air conditioners. The research, published last month in the Journal of Geophysical Research, investigates the effects of air-conditioning systems on air temperature and examines their electricity consumption for a semiarid urban environment.

With Europe and the United States slow to ban the pesticides that science says is probably drastically harming our bee populations, could one of the world's most venomous spiders hold one solution to saving our pollinators?

Using too much fertilizer is a very bad idea. It doesn't help crops, and in fact can be harmful to them. Excess fertilizer runs off and contributes to river and stream contamination and a new study shows that it is bad for the climate too!
But farmers sometimes think that if some is good, more MUST be better!
Helping farmers around the globe apply more precise amounts of fertilizer nitrogen is a great objective that can improve crop yields, reduce pollution, and combat climate change.
That's the conclusion of a study published this week in the journal Proceedings of the National Academy of Sciences. In the paper, researchers at Michigan State University (MSU) provide an improved prediction of nitrogen fertilizer's contribution to greenhouse gas emissions from agricultural fields.
