Una nueva investigación ha encontrado metilmercurio, una potente neurotoxina, en el hielo marino del Océano Antártico. Publicado en la revista Nature Microbiology, los resultados son los primeros en demostrar que las bacterias del hielo marino pueden cambiar el mercurio en metilmercurio, una forma más tóxica que puede contaminar el medio marino, incluidos los peces y las aves.

New research has found methylmercury – a potent neurotoxin – in sea ice in the Southern Ocean.

Published today in the journal Nature Microbiology, the results are the first to show that sea-ice bacteria can change mercury into methylmercury, a more toxic form that can contaminate the marine environment, including fish and birds.

If ingested, methylmercury can travel to the brain, causing developmental and physical problems in foetuses, infants and children.

Construir en Rhode Island no es fácil. Los huracanes y las tormentas tropicales barren sus pueblos pintorescos de la costa, interrumpiendo los fines de semana de verano perfectos. Fríos inviernos traen ventiscas que pueden bloquear todo el estado. Y cada temporada, característicos vientos salados corrosivos muerden la costa como si fueran enviados por una Gran Bretaña en ebullición por la primera colonia americana en declarar la independencia.

Heterogeneous parallel computing combines various processing elements with different characteristics that share a single memory system. Normally multiple cores (like the 'multicores' in some smart phones or personal computers) are combined with graphic cards and other components to process large quantities of data.

"We hope to help transform code so that it can be run in heterogeneous parallel platforms with multiple graphic cards and reconfigurable hardware," explains the project's coordinator, José Daniel García, an associate professor in UC3M's Computer Science department. "We've made significant improvements in both performance and energy efficiency, comparable to those that can be made with a manual development process; the difference is that with a manual development process, we need months of engineering, while with our semiautomatic process we can do the same tasks in a few days."
