[:es]Litio-ioizko bateriak birziklatzeko metodo jasangarriagoa garatu dute[:]
[:es]Kaliforniako Unibertsitateko nanoingeniariek litio-ioizko bateriak birziklatzeko metodo merkea eta eraginkorra garatu dute. Batez ere, burdin-litio fosfatoaz (LiFePO4 ) sortutako katodoak birziklatzeko da eraginkorra. Bateria horiek kobaltoa edo nikela erabiltzen duten beste litio-ioizko bateriak baino merkeagoak, seguruagoak eta iraunkorragoak dira. Abantaila horiek direla eta, maiz erabiltzen dira erreminta elektrikoetan, ibilgailu elektrikoetan zein sare elektrikoetan. Arazoa da…

[:es]Microbes’ mystery DNA helps defeat viruses—and has genome-editing potential[:]
[:es]Seven years ago, an understanding of nature inspired a revolutionary new technology, when researchers turned a defense system used by bacteria to thwart viruses into the gene-editing tool now known as CRISPR. But for another emerging gene editor the understanding has lagged the applications. For several years, researchers have been adapting retrons—mysterious complexes of DNA,…
