15 arbres parmi les plus beaux de la planète, une vraie bouffée d'air frais Chers arbres, permettez-moi de vous conter ; vous absorbez le dioxyde de carbone pour produire l'oxygène que nous respirons, vous séquestrez le carbone et fournissez un abri pour de nombreuses créatures. Il y a plusieurs raisons pour lesquelles nous devrions tous être comme des hippies à pleurer chacun de vos morts, mais dans le cadre de cet article, nous allons nous concentrer uniquement sur les plus incroyables d'entre vous. Certes, tous ces arbres étonnants ne sont pas QUE des arbres (le wisteria est une liane, le rhododendron un arbuste, et le bambou appartient techniquement à la famille des graminées), mais nous allons leur donner un laissez-passer pour cette fois-ci, tellement ils sont incroyables, immenses et magnifiques.

Taking the lead out of a promising solar cell: Environmentally friendly solar cell pushes forward the 'next big thing in photovoltaics' Northwestern University researchers are the first to develop a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly solar cell can be made easily using "bench" chemistry -- no fancy equipment or hazardous materials. "This is a breakthrough in taking the lead out of a very promising type of solar cell, called a perovskite," said Mercouri G. Kanatzidis, an inorganic chemist with expertise in dealing with tin. "Tin is a very viable material, and we have shown the material does work as an efficient solar cell." Kanatzidis, who led the research, is the Charles E. and Emma H. The new solar cell uses a structure called a perovskite but with tin instead of lead as the light-absorbing material. Kanatzidis developed, synthesized and analyzed the material. Details of the lead-free solar cell will be published May 4 by the journal Nature Photonics. A thin layer of gold caps off the solar-cell sandwich.

An Apple a Day... Could Give You Cancer? | Rachel Lincoln Sarnoff Do you love apples? You might want to find a new favorite fruit. A new report from the Environmental Working Group found that 80 percent of apples are coated with a pesticide that's banned in Europe because it could be carcinogenic. European regulators were so worried enough about the connection between diphenylamine and nitrosamines, a family of potent cancer-causing chemicals that they banned its use on apples and pears in June 2012. In the United States, farmers treat conventionally-grown apples with the EU-banned pesticide -- commonly known as DPA -- after the harvest to prevent blackening or browning of fruit skin during cold storage. European regulators worry that during this time, carcinogenic nitrosamines could be generated when DPA combines with nitrogen, an element that's common to our environment. Tests of raw apples conducted by the U.S. The average concentration of DPA on U.S. apples is about .42 parts per million. Facts like this make me mad. It just isn't fair. 1. 2.
