Social networks predict the life and death of honey bees

Honey bee workers take on different tasks as they age. The authors study the individuals' social networks and show that interaction patterns predict task allocation and developmental trajectories.

    When nature strikes with force, the effects can be devastating. It is critically important to better study and understand natural hazards to help mitigate against their effects. In this collection, we focus on geological hazards such as volcanic eruptions, tectonic earthquakes and mass movements.

  • Are you an Early Career Research (ECR) interested in peer review? Join the training programme at Nature Communications, providing an opportunity to learn and get involved in peer review supervised by professional editors. Previous experience with peer review is not required. We encourage enrolment of ECRs from diverse backgrounds and locations. Deadline for applications: 14th June 2021

  • Andreev reflection is normally known to occur at a metal-superconductor interface. Here, Hashisaka et al. observe an Andreev-like process in a narrow junction between fractional and integer quantum Hall states originating from a topological quantum many-body effect instead of superconductivity.

  • Composites which are made up of a single polymer, and yet allow modulation of the mechanical properties of the matrix without stress concentration, are challenging to fabricate. Here, the authors design a selfreinforced homocomposite alginate hydrogel with enhanced mechanical properties incorporating soft dendritic alginate colloids in the matrix and demonstrate its application in extrusion printing.

  • The broken-symmetry edge states that are the hallmark of the quantum Hall effect in graphene have eluded spatial measurements. Here, the authors spatially map the quantum Hall broken-symmetry edge states using atomic force microscopy and show a gapped ground state proceeding from the bulk through to the quantum Hall edge boundary.

  • Predicting and controlling the (in)stability of thin shells are important tasks in many practical applications but hampered by the presence of imperfections. Here Yan et al. show that when the material composition is magnetic the conditions for collapse can simply be readjusted with external fields.

  • Marine snow is a major route through which photosynthetically fixed carbon is transported to the deep ocean, but the factors affecting flux are largely unknown. Here the authors use high frequency imaging of marine snow particles collected during phytoplankton blooms to categorize and quantify transport.

  • The evolution of multicellular life is hypothesized to have been promoted by rising oxygen levels. Through experimental evolution and modeling, Bozdag et al. demonstrate that our planet’s first oxygenation would have strongly constrained, not promoted, the evolution of multicellular life.

  • Most studies have examined the impacts of human-driven climate change on mean or extreme climate variables and have neglected to explore interrelated drought features. Here, the authors show that the presence of human activity has increased the number and maximum length and intensity of drought events across the globe.

  • Clean water is a fundamental resource, yet the economic impacts of pollution, drinking water availability, and greenhouse gas emissions from freshwaters are unknown. Here the authors combine models with economic assessments and find trillions of dollars in savings by mitigating lake methane emissions.

  • Quantifying land use change is critical in tackling global challenges related to food, climate and biodiversity. Here the authors show that land use change has affected 32 % of the global land area in six decades (1960- 2019) by combining multiple open datasets to create the HIstoric Land Dynamics Assessment +.

  • Established climate mitigation modelling relies on controversial negative emissions and unprecedented technological change, but neglects to consider degrowth scenarios. Here the authors show that degrowth scenarios minimize many key risks for feasibility and sustainability and thus need to be thoroughly assessed.

  • Agricultural sectors receive US$600 billion per year in government support, providing incentives for GHG emission-intensive production. Here, the authors show that removing this support will not reduce global GHG emissions by much; rather it will need to be radically redirected to contribute to climate change mitigation.

  • Proteins and peptides are amongst the most widely used research reagents but often their quality is inadequate and can result in poor data reproducibility. Here we propose a simple set of guidelines that, when correctly applied to protein reagents should provide more reliable experimental data.

  • Transient transfections are routinely used in basic and synthetic biology studies to unravel pathway regulation and to probe and characterise circuit designs. As each experiment has a component of intrinsic variability, reporter gene expression is usually normalized with co-delivered genes that act as transfection controls. Recent reports in mammalian cells highlight how resource competition for gene expression leads to biases in data interpretation, with a direct impact on co-transfection experiments. Here we define the connection between resource competition and transient transfection experiments and discuss possible alternatives. Our aim is to raise awareness within the community and stimulate discussion to include such considerations in future experimental designs, for the development of better transfection controls.

  • Singleton and colleagues publish in Nature Communications an intervention study to reduce antimicrobial usage in companion animal practice. They identify significant reductions in antimicrobial usage with their more active intervention group over approximately a 6-month period. The study offers an exciting way forward to explore further the trial interventions and assess alternative methods to improve antimicrobial stewardship in veterinary practice.
