After impact the asteroid that hit the earth’s surface 65 million years ago, nearly 80% of marine life became extinct and the climate cooled dramatically. An international team of researchers in Science now reveals that the ocean, marine productivity or photosynthesis recovered in less than a century.
The new geochemical study by researchers at the University of Bremen (Germany), the Massachusetts Institute of Technology (MIT, its acronym in English), and the University of Jena (Germany) shows that photosynthesis, the basis of the marine food web, was only interrupted for 100 years, so that his recovery was “surprisingly” fast.
“The oceans were able to recover quickly after the environmental disaster associated with impact of the meteorite, and apparently could reorganize ecosystems very rapidly,

A team of researchers at the University of Zaragoza (UNIZAR) and the Institut d’Astrophysique Spatiale (IAS, France) has developed a scintillator bolometer, a device that scientists will attempt to detect dark matter in the universe and that has been tested in the Underground Laboratory Canfranc (Huesca).
“One of the challenges of current physics is to determine the nature of dark matter, which although appears to be the fourth of the matter in the universe, can not be observed directly, so we try to detect it as the prototype we have developed “explains to SINC ABANCENS Eduardo Garcia, a researcher at the Laboratory of Nuclear Physics and Astroparticle of UNIZAR.

Conduct a “comprehensive list of all possible molecules [1], as is the ambition of Jean-Louis Reymond and his team from the Department of Chemistry and Biochemistry, University of Bern. With powerful computers, they have combined all ways possible, while respecting the known chemical laws, the main atoms forming the skeleton of organic molecules: carbon, nitrogen, oxygen, sulfur and chlorine.
