On May 4, 1700 the town of Salamanca made prayers to the Virgen de la Vega for rain. This fact, apparently just reached the category of historical anecdote may be part of a line almost unexplored climate research: the historical record. Miguel Angel Fuertes, scientist in the Department of Geology at the University of Salamanca, has followed this trail in the records of capiturales chapter of the Cathedral of Salamanca, a faithful witness of all types of incidents, including weather.
 “The idea is to obtain paleoclimatic data from different sources,” says Miguel Angel Fuertes. “Recent data from high resolution,” ie less spaced in time that they can provide other data, such as looking at marine sediments his new roommate.
To do this, ideally you have data of temperature or atmospheric pressure taken with instruments, but are only reliable from the mid eighteenth century, so “if we try to study long-term changes in climate, we need information that goes beyond” explains the expert.

 An interdisciplinary team of researchers comprises chemists, physicists and mathematicians from the Technical University of Eindhoven (Netherlands) and the University of Ulm produced for the first time, images with high resolution three-dimensional ( 3D) from inside a cell polymer photovoltaic (PV) [1]. This provides new essential information on the nanostructure of polymer PV cells and its influence on their performance. These findings were published September 13, 2009 in the online edition of the journal Nature Materials [2].

1. • Mobile no battery and are loaded MP3 alone are two of the possible applications.
2. • UPC Researchers study how wireless energy transfer between satellites.
“It’s time to cut the umbilical cord. So Eduard Alarcon refers to the power cable which inevitably accompanies every electronic device, from computers to household appliances.
