Landsat satellite images reveal coherent interannual beach narrowing and widening across California in response to changes in central North Pacific wave power, with no 1985-2021 statewide mean shoreline loss. Low wave power (beach widening) correlates poorly with the El Niño climate index.

A key component of quantum error correction is the decoding algorithm, which needs to be accurate but also with a computational overhead that doesn’t lead to backlogs and allows fast logical clock rates. Here, the authors show an FPGA-driven decoder featuring a coarse-grained parallel architecture and on-the-fly error model updates, allowing both high accuracy and real-time operation.

This paper describes within-host evolutionary dynamics of SARS-CoV-2 during an outbreak in three carnivore species. Positive selection and the emergence of potentially species-specific mutations were observed in lion and hyena samples.

Across a global dataset of over 11,000 naturalized alien plant species, the authors find that species are likely to naturalize both in regions with climates and floras similar to those in their native ranges, and in regions with a lower diversity or stronger human impact than in their native range.

An initial draft of the human pangenome is presented and made publicly available by the Human Pangenome Reference Consortium; the draft contains 94 de novo haplotype assemblies from 47 ancestrally diverse individuals.

Translation initiation and elongation factors can be targets for cancer treatment. Here, the authors show that inhibiting translation elongation through eIF5A impairs mitochondrial function, slowing the proliferation of tumour cells.

The role of the Nucleus Reuniens (NR)-CA1 pathway in contextual fear conditioning remains unknown. Here, the authors show that the NR-CA1 pathway transmits a signal that actively suppresses fear memory retrieval in CA1 during fearful behavior.

Hepatitis C virus (HCV) variability and its phenotypic consequences aren’t well studied in relation to viral replication fitness and disease severity. Here, the authors identify a replication-enhancing domain in non-structural protein 5A, linking high replication fitness to severe disease outcomes, with implications for understanding HCV pathogenesis in immunocompromised patients.

The variability in clinical outcomes of SARS-CoV-2 infection is partly due to deficiencies in production or response to type I interferons (IFN). Here, the authors describe a FIP200-dependent lysosomal degradation pathway, independent of canonical autophagy and type I IFN, that restricts SARS-CoV-2 replication, offering insights into critical COVID-19 pneumonia mechanisms.
