Antivirales y vacunas: la ayuda para frenar al coronavirus está en camino
Una semana después de que China notificara a la OMS los primeros casos de una neumonía severa de origen desconocido, se identificó el agente causante: el nuevo coronavirus SARS-CoV-2. Unos días después ya estaba disponible su genoma. En poco menos de tres meses disponemos de más de 970 artículos científicos en la base de datos PubMed.
How China’s “Bat Woman” Hunted Down Viruses from SARS to the New Coronavirus

COVID-19ak ekonomian izan ditzakeen epe laburreko ondorioez ahazteko eskatu du The Lancet-ek
The Lancet aldizkariak gogor jo du hainbat herrialdetan COVID-19 gaixotasuna ez zabaltzeko hartzen ari diren neurri eskasen aurka. Editorialean adierazi dutenez, politikariek hartutako neurriak motelegiak eta eskasak izan dira, kasu askotan. Arriskuak hartu eta modu erabakigarriagoan jokatzeko eskatu die politikariei: haien irudi publikoak eta ekonomiak jasan ditzakeen epe laburreko ondorioez ahaztu, eta gizateriaren osasunak eskatzen duen erantzukizunez joka dezatela.
Why did nearly a million king penguins vanish without a trace?
Where on Earth, wondered Henri Weimerskirch, were all the penguins? It was early 2017. Colleagues had sent the seabird ecologist aerial photos of Île aux Cochons, a barren volcanic island halfway between Madagascar and Antarctica that humans rarely visit. The images revealed vast areas of bare rock that, just a few decades before, had been crowded with some 500,000 pairs of nesting king penguins and their chicks. It appeared that the colony—the world’s largest king penguin aggregation and the second biggest colony of any of the 18 penguin species—had shrunk by 90%. Nearly 900,000 of the regal, meter-high, black, white, and orange birds had disappeared without a trace. “It was really incredible, completely unexpected,” recalls Weimerskirch, who works at the French national research agency CNRS.
De cómo el coronavirus se coló por las ‘rendijas’ del sistema
Aunque faltan muchas incógnitas por resolver, ya tenemos algunas pistas de por qué el coronavirus SARS-CoV-2 se ha saltado todas las barreras de contención. Su capacidad de contagiar sigilosamente y nuestra soberbia, entre las claves.
The coronavirus pandemic in five powerful charts
From papers published to carbon emissions to confirmed cases, these data reveal an unprecedented viral outbreak and its impacts around the world.
Itsasoari begira
Ozeanokoak dira planetako ekosistemarik ezezagunenetakoak. Han daude gizateriaren hurrengo erronka zientifikorik handienak, Nazio Batuen arabera. Indar eta ahalmen ikaragarriko gunea da, baina egoera kritikoan dago. Gizartea itsasora begira jarri eta erronka horiei heltzeko deia egin du UNESCOk. Itsas Zientzien Hamarkada izendatu du 2021-2030ekoa, itsasoari begira jar gaitezen. Hamarkadako erronka nagusiez hitz egin dugu itsasoko lau aditurekin.
