Rare but serious cardiac disease side effects have been linked to COVID-19 vaccinations, especially in young people. Here, the authors find very little evidence of an association between vaccination and mortality, except for in females after a non mRNA vaccine, but show an increased risk of death following COVID-19 infection
Consuming microplastics is known to harm marine wildlife in several ways, but effects on the microbiome are understudied. Here the authors demonstrate that two species of wild seabirds with larger amounts of microplastic in their guts had fewer commensal gut microbial species but more pathogens.
The unusual radar properties of icy satellites appear to be correlated and distributed along a spectrum of values. Only modelling including the coherent backscatter opposition effect can reproduce this behaviour.
An in vitro technique to drop a Y chromosome and duplicate an X chromosome could expand the reach of fertility treatments in the future, although translation to humans remains an open question.
It's a critical time for the diversity of life in Europe's rivers and
TNC and our partners work to protect Africa's critical freshwater resources and contribute to our global goals to conserve 1 million kilometers of rivers and 30 million hectares of wetlands by 2030.
Genomic and demographic analyses of the ‘Southern Resident’ killer whales in the North Pacific find that strong inbreeding depression is inhibiting growth of this small and isolated population. The findings help to explain why this group of whales is still declining despite 50 years of conservation efforts.
