[:es]Una estrella binaria en la ‘pupila’ de Sauron[:]
Con la ayuda del telescopio espacial TESS, un equipo científico liderado desde el Centro de Astrobiología ha observado el núcleo de ocho nebulosas planetarias. En siete de ellas, incluida la famosa nebulosa de la Hélice, han detectado signos claros de variabilidad en la curva de luz de su estrella central, lo que sugiere que la…

[:es]Materia ilunaren zantzutzat jo izan den seinalea baztertu dute[:]
Partikulen fisikaren hainbat ereduk proposatu izan dute materia iluna pixkanaka deskonposatu eta materia arrunt bihur litekeela, eta prozesu horretan fotoiak askatu litezkeela. Hala, proposatu izan da zenbait galaxiatan ikusitako 3,5 kiloelektronvolteko X izpien isuri-mota bat izan zitekeela horren froga. Science aldizkarian argitaratutako ikerketa batek, ordea, ezeztatu egin du hori hala denik. Ikerketaren arabera, hainbat galaxiatan…

[:es]Nuevos modelos matemáticos aconsejan seguir con los niveles de confinamiento actuales y hacer más test[:]
Investigadores de las universidades de Zaragoza y Carlos III de Madrid han analizado la efectividad de las estrategias de distanciamiento social ante una pandemia como la de COVID-19. Los resultados muestran que un confinamiento total no resuelve el problema si no se toman medidas como la realización de pruebas de diagnóstico a gran escala, el…

[:es]Mysterious chemical found in dead cat’s brain reopens debate over mercury poisoning disaster[:]
The city of Minamata, Japan, is dotted with monuments commemorating victims of an industrial mass poisoning decades ago. High in the hills, a small stone memorial honors other deaths—of cats sacrificed in secret to science. Now, after restudying the remains of one of those cats, a team of scientists is arguing, controversially, that the long-standing…
