Chronic infection with SARS-CoV-2 leads to the emergence of viral variants that show reduced susceptibility to neutralizing antibodies in an immunosuppressed individual treated with convalescent plasma.

Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

Sea otters recolonizing an estuary in California indirectly reduce erosion by reducing burrowing crab abundance, suggesting that restoring predators could be a key mechanism to improve the stability of coastal wetlands and other ecosystems.

Sera from vaccinated individuals and some monoclonal antibodies show a modest reduction in neutralizing activity against the B.1.1.7 variant of SARS-CoV-2; but the E484K substitution leads to a considerable loss of neutralizing activity.

Most Amazon tree species are rare but a small proportion are common across the region. The authors show that different species are hyperdominant in different size classes and that hyperdominance is more phylogenetically restricted for larger canopy trees than for smaller understory ones.

m6Am is a modification of the 5′ end of mRNAs catalyzed by PCIF1. Here, Zhang et al. show that HIV infection induces a decrease in m6Am of cellular mRNAs through Vpr-mediated PCIF1 ubiquitination and degradation, resulting in increased HIV replication through regulation of host transcription factors.

Fishing has had a profound impact on global reef shark populations, and the absence or presence of sharks is strongly correlated with national socio-economic conditions and reef governance.

Differential cross-reactivity to haemagglutinin of various influenza B viruses shows lineage-specific susceptibility that varies between birth cohorts and was determined by early exposure to specific strains.

Although previous work indicated that the antitumor effects of anti-CD47 require macrophage phagocytosis of tumor cells, new work done in immunocompetent mice bearing syngeneic tumors reveals a key role for dendritic cell cross-priming of CD8⁺ T cells.

Analysing >1,700 inventory plots from the Amazon Tree Diversity Network, the authors show that the majority of Amazon tree species can occupy floodplains and that patterns of species turnover are closely linked to regional flood patterns.

Current seasonal influenza vaccines lack efficacy against drifted or pandemic virus strains, and the development of novel vaccines that elicit broader immunity represents a public health priority. Here, Nabel and colleagues discuss approaches to improve vaccine efficacy which harness new insights from influenza antigen structure and human immunity, highlighting major targets, vaccines in development and ongoing challenges.

A molecular mechanism for brain-specific angiogenesis operates under the control of Wnt7a/b ligands.

There is an unmet medical need for the detection and treatment of early adenomas to prevent their progression to malignant disease. Here the authors show that orally administered E. coli Nissle 1917 can selectively colonize adenomas in mouse models and in patients as a detection tool, as well as deliver immunotherapeutics for colorectal neoplasia treatment.
