Collective anti-predator escape manoeuvres through optimal attack and avoidance strategies

The paper investigates collective escape patterns in sardines under predator attack, showing fountain effects arise from optimal escape rules and predator strategies.

A new and widespread group of fish apicomplexan parasites

The paper identifies a new group of fish-infecting apicomplexan parasites, ichthyocolids, related to corallicolids, and shows they lack chlorophyll biosynthesis genes in their apicoplast.

Increased thermal tolerance under anoxic conditions in an extremophile fish from hot sulfur springs in Mexico

This study examines thermal tolerance of two extremophile fish species under normoxic and hypoxic conditions, finding P. sulphuraria has higher CTmax under hypoxia compared to G. eurystoma.

Reproductive individuality of clonal fish raised in near-identical environments and its link to early-life behavioural individuality

This study shows that clonal fish raised in identical environments exhibit consistent reproductive differences and early-life behavioral individuality, which predict growth and offspring size.

A critical role of retinoic acid concentration for the induction of a fully human-like atrial phenotype in hiPSC-CM

This study shows that 1 μM retinoic acid is necessary and sufficient to induce a fully human-like atrial phenotype in hiPSC-CMs, overcoming methodological challenges in RA concentration control.

Ephemeral resources promote adaptive sociality in wild guppies

This study shows that wild guppies increase sociality in response to ephemeral food patches, demonstrating adaptive social flexibility in dynamic resource environments.

Self-organization and information transfer in Antarctic krill swarms

This study analyzes the movement and interaction patterns of Antarctic krill swarms to uncover the rules governing their formation and maintenance.

Causal evidence for the adaptive benefits of social foraging in the wild

The paper manipulates social environments in wild guppies to show that increased conspecifics improve foraging success, with unexpected sex differences in social benefit.

Group-level patterns emerge from individual speed as revealed by an extremely social robotic fish

This study shows individual speed differences in guppies shape collective behavior patterns through robotic fish experiments.

African swine fever virus-like integrated elements in a soft tick genome - an ancient virus vector arms race?

The paper identifies ASFV-like integrated elements in soft tick genomes, suggesting an ancient co-evolutionary arms race between ticks and ASFV.

Consistent behavioural syndrome across seasons in an invasive freshwater fish

The paper investigates whether dispersing guppies exhibit different behavioral traits than those remaining in the source population, finding consistent behavioral syndromes across seasons and populations.

Neolithic genomes reveal a distinct ancient HLA allele pool and population transformation in Europe

The paper analyzes Neolithic genomes from Germany to show genetic heterogeneity and a high hunter-gatherer ancestry component in a WBC population, with distinct HLA allele pools related to viral immunity.

Ancient Yersinia pestis genomes provide no evidence for the origins or spread of the Justinianic Plague

The paper reanalyzes ancient Yersinia pestis genomes to challenge the link between the Justinianic Plague and the identified genomes, suggesting the lower coverage genome may instead relate to the Black Death.

Proteome thermal stability reflects organ physiology and identifies drug-target engagement in vivo

This study introduces tissue-TPP and blood-CETSA to measure proteome thermal stability, revealing organ physiology and drug-target engagement in vivo.

Ancient Yersinia pestis genomes from across Western Europe reveal early diversification during the First Pandemic (541-750)

This study reconstructs six new Yersinia pestis genomes from the First Pandemic (541-750) and identifies genetic diversity and potential convergent evolution with later pandemics.

A phylogeography of the second plague pandemic revealed through the analysis of historical Y. pestis genomes

This study analyzes historical Y. pestis genomes to trace the phylogeography of the second plague pandemic, revealing patterns of genetic diversity and virulence gene loss.

Females facilitate male patch discovery in a wild fish population

The paper shows that male guppies find fewer food patches without females, suggesting sex-dependent social mechanisms influence foraging success in wild populations.

Social networks in the presence and absence of visual cues

This study compares social dynamics between cave and surface Atlantic mollies under different densities, finding surface mollies maintain social interactions better at low density.

Quorums enable optimal pooling of independent judgements

The paper shows majority voting is often sub-optimal for collective decisions and proposes quorum-based decision-making as a better alternative, applicable to groups with aligned interests.

Modern wolves trace their origin to a late Pleistocene expansion from Beringia

This study traces the origin of modern wolves to a late Pleistocene expansion from Beringia, using ancient mitochondrial genomes and spatial-temporal modeling.

Guppies prefer to follow large (robot) leaders irrespective of own size

The study shows that guppies follow larger robotic fish leaders regardless of their own size or risk-taking behavior, indicating leadership preference is based on size rather than behavior.

Neolithic and Medieval virus genomes reveal complex evolution of Hepatitis B

This study analyzes three ancient HBV genomes from European skeletons, showing HBV circulation for 7000 years and distinct lineages that may have gone extinct.

Using a robotic fish to investigate individual differences in social responsiveness in the guppy

This study uses a robotic fish to examine individual differences in social responsiveness in guppies, finding that responsiveness is an independent trait separate from boldness and activity.

Individual- and population-level drivers of consistent foraging success across environments

The paper investigates individual and population-level factors influencing foraging success across environments in guppies, finding consistent individual differences driven by social traits and sex ratios.

The Stone Age Plague: 1000 years of Persistence in Eurasia

This study identifies six new Yersinia pestis genomes from the European Late Neolithic to Bronze Age, suggesting a single genetic clade that may have persisted in Europe until the mid Bronze Age.
