    Deep sampling of Hawaiian Caenorhabditis elegans reveals high genetic diversity and admixture with global populations

    Tim A Crombie et al.
    Hawaiian Caenorhabditis elegans harbor high levels of genetic diversity that might represent the complex patterns of ancestral diversity in the species prior to human influence.

    Thousands of novel translated open reading frames in humans inferred by ribosome footprint profiling

    Anil Raj et al.
    Over 7,000 novel translated sequences have been identified from human cells, including several hundred in annotated noncoding RNA, pseudogenes and de novo assembled transcripts.

    Oviductal estrogen receptor α signaling prevents protease-mediated embryo death

    Wipawee Winuthayanon et al.
    Cyclic estrogen signaling in oviduct epithelial cells suppresses oviduct luminal protease activity to allow survival and development of preimplantation embryos

    GWAS of three molecular traits highlights core genes and pathways alongside a highly polygenic background

    Nasa Sinnott-Armstrong et al.
    Across urate, IGF-1, and testosterone, thousands of dispersed variants contribute to heritability, while previously characterized core pathways are highly enriched for associations and reveal feedback mechanisms governing serum biomarker levels.

    A phenotypic screening platform utilising human spermatozoa identifies compounds with contraceptive activity

    Franz S Gruber et al.
    A high-throughput phenotypic human sperm screening platform was developed which allows for major drug discovery programmes for male contraception.

    Reduced signal for polygenic adaptation of height in UK Biobank

    Jeremy J Berg et al.
    Many prior signals of polygenic adaptation on human height do not replicate in the UK Biobank.

    Impact of COVID-19-related disruptions to measles, meningococcal A, and yellow fever vaccination in 10 countries

    Katy AM Gaythorpe et al.
    Routine and campaign vaccination disruption in 2020 may lead to measles outbreaks and yellow fever burden increases in some countries, but is unlikely to greatly increase meningococcal A burden.

    Multiple knockout mouse models reveal lincRNAs are required for life and brain development

    Martin Sauvageau et al.
    Long intergenic noncoding RNA molecules (lincRNAs) are shown to have critical roles in mammalian development and physiology in vivo.

    Rapid evolution of the human mutation spectrum

    Kelley Harris, Jonathan K Pritchard
    Heritable mutations tend to occur within different DNA sequence contexts in different human populations, suggesting that DNA replication and repair often change in efficacy over only a few hundred generations of evolution.
