U.S. researchers confirm, in a study published this week in Science, that the actual effects of CO2 in the atmosphere are different from those that predict the Kyoto Protocol and the Intergovernmental Panel on Climate Change (IPCC), because they forget to calculate the interaction of gases with aerosols. The new finding would help to improve strategies to curb global warming.
 Researchers from Columbia University in New York (USA) and the Goddard Institute for Space Studies at NASA (USA) have used a computer simulation that links the atmospheric composition and climate. The results show that the interactions between gases and aerosols can alter the accumulation of greenhouse gases in the atmosphere.

Researchers at the University College Dublin in Ireland, the Smithsonian Institute in Washington DC in the United States and the “Oxford University in the United Kingdom have detected a sudden decrease in plant diversity in the Former Greenland, there are 200 million years, coupled with a relatively small increase in the level of atmospheric carbon dioxide.

 Once is not custom, we open this week under “innovation” of U.S. BE a contribution of Dr. Roland Pellenq, research director at CNRS, which is living the high scientific level in the Department of Environmental and Civil Engineering, Faculty of Engineering at MIT. Inter-, multi-or transdisciplinarity requires Roland Pellenq physicist fundamental development work and lessons to supply teachers and researchers in engineering with concepts and principles belonging to his discipline. Roland Pellenq speaks here of “Liquid Stone“, a joint MIT-Linking on the molecular structure of the cement produced its first results. On behalf of the MS & T, I thank him warmly for his outstanding support to BE the United States.
- A. Mynard, tied for Science and Technology, Boston (September 9, 2009)
The strength comes from the disorder, not a geometrical arrangement
A natural form of cement was used in the Roman Empire in the construction of a vast system of aqueducts and other ancient edifices of many Mediterranean countries.

The warming temperature of ocean currents in the Arctic over the last 30 years has triggered the release of methane, a potent greenhouse gas emissions, usually stored as methane hydrates in deep ocean sediments.
Scientists at the NOCS (National Oceanography Center, Southampton, National Oceanography Center in Southampton), in collaboration with researchers from the Universities of Birmingham, London, Royal Holloway and the IFM-GEOMAR in Germany have revealed that real plumes bubbles of methane escaping from around 250 “chimney” located between 150 and 400 meters deep on the ocean floor,

 The California company Better Place has been chosen August 26, 2009 by the Ministry of Economy, Trade and Industry of Japan (METI) to conduct a feasibility study on the deployment of a battery change for taxis electric. It will work in close collaboration with Nihon Kotsu, the first taxi company in Tokyo,
