Only three Spike mutations enable murine SARS-CoV-2 infection, which is still strictly ACE2 dependent and causes a COVID-19-like disease in mice with immunopathology-driven lung damage.
Dendritic calcium spikes translocate hippocampal place fields by inducing a non-Hebbian form of bidirectional synaptic plasticity that operates over a seconds-long timescale called behavioral timescale synaptic plasticity.
ZAF (Zebrafish Automated Feeder) is the first fully automated, easy to build, and open source fish feeder designed for small and medium sized labs of which there are an estimated 3250 in 100 countries working with Zebrafish alone today.
Single-molecule analysis of SARS-CoV-2 RNA identifies significant heterogeneity in cellular viral RNA levels and highlights slower replication kinetics for the Alpha variant compared to the Victoria strain.
Short-ranged and random connectivity are sufficient to explain complex, long-range activity patterns observed in macaque motor cortex that are, moreover, flexibly adaptable to behavior.
Direct imaging of individual molecules of the tip-link protein PCDH15 in mouse stereocilia shows that it assembles as a dimer, forms complexes that span stereocilia, and occurs in clusters with multiple copies of the PCDH15 dimer.

Zebrafish early embryos initially package their developmental genes and enhancers in 'active' chromatin that subsequently receives polycomb repressive complex 1 (PRC1)-mediated histone H2A ubiquitylation, which confers silencing/poising – prior to Aebp2-PRC2-guided H3K27me3 addition.
Highly specific gene manipulation in mouse thymic epithelial cells (TECs) shows that fine-tuning of β-catenin expression is required for TECs to generate an optimal thymic microenvironment to support T-cell development.
pyControl is an open-source tool that makes it easy to specify complex behavioural tasks, run them at scale on low-cost hardware, and communicate task logic to other researchers.

While predators can clearly reduce mosquito populations by consumption, they can also have non-consumptive effects on mosquito body size and oviposition behavior, and these effects on vector traits can influence infectious disease dynamics.
