Ancient DNA analyses reveal that Viking Age migrations from Scandinavia resulted in differential influxes of ancestry to different parts of Europe, and the increased presence of non-local ancestry within Scandinavia.

The 1000 Genomes Project has completed its pilot phase, sequencing the whole genomes of 179 individuals and characterizing all the protein-coding sequences of many others. Welcome to the third phase of human genomics. See Article p.1061

A characteristic of costal-pelagic fishes is their large population size fluctuations, yet the drivers remain elusive. Here, the authors analyze a 45-year timeseries of nitrogen stable isotopes measured in larvae of Northern Anchovy and find that high energy transfer efficiency from the base of the food web up to young larvae confers high survival and recruitment to the adult population.

Genome sequences of Bos species are sequenced and compared to determine their phylogeny and evolutionary history. Introgression pathways for genes under domestication selection are identified.

Artificial nanopores can perform selective gating of molecules analogous to transmembrane proteins. Here, the authors design a DNA origami pore with a controllable lid for size-selective gating and translocation of macromolecules and evaluate its biosensing properties by single particle assay.

Establishing the relative transmissibility of emerging variants of SARS-CoV-2 is key for pandemic management. Here, the authors use full-population administrative data from Denmark linked to PCR test results and estimate that the Alpha variant was ~60% higher than other strains circulating in early 2021.

Bikaverin is a fungal-derived tetracyclic polyketide with antibiotic, antifungal and anticancer properties. Here, the authors employ various pathway engineering strategies to achieve high level production of bikaverin in baker’s yeast.

In this study, the authors investigate immune responses following a third (booster) SARS-CoV-2 vaccination dose in a cohort of healthcare professionals in Denmark. They find stronger immune responses among those with a prior infection, and correlation between lower antibody responses and higher risk of subsequent breakthrough infection.

Entanglement between single photons and solid-state emitters is a key component for photonic quantum computing and networks. Here, using a single electron spin in a quantum dot, the authors present a deterministic photon source achieving three-qubit entanglement of one electron spin and two photons.

Sequences of 137 ancient and 502 modern human genomes illuminate the population history of the Eurasian steppes after the Bronze Age and document the replacement of Indo-European speakers of West Eurasian ancestry by Turkic-speaking groups of East Asian ancestry.

Genome-wide analyses of vaccine antibody responses in 2,499 infants from Uganda, South Africa and Burkina Faso identify associations between specific HLA genes and response to eight vaccines, providing insights that could be considered for population-adjusted vaccine design strategies.

The first genome sequence of an ancient human is reported. It comes from an approximately 4,000-year-old permafrost-preserved hair from a male from the first known culture to settle in Greenland. Functional single-nucleotide polymorphism (SNP) assessment is used to assign possible phenotypic characteristics and high-confidence SNPs are compared to those of contemporary populations to find those most closely related to the individual.

Whales, dolphins and porpoises are adapted to various aquatic habitats. Here, Zhou et al. show that polymorphisms associated with renal function and the urea cycle have undergone selection in the freshwater Yangtze finless porpoise and provide genomic evidence of incipient speciation.

Optimal management of overfished stocks through maximum sustainable yield targets could increase fish catch by 10.6 Megatons, and reduce the demand for other protein sources, according to an analysis combining the fish-stock and agriculture-food market models and scenario analysis.

Individuals homozygous for the CCR5-∆32 allele have a 21% increase in mortality rate in the UK Biobank cohort. In light of the CRISPR-baby scandal, this work highlights the need for understanding the unintended consequences of introducing mutations in humans.
