A new computer controlled behavioral assay and integrated training chamber for individual Drosophila larvae shows that larvae learn all at once and create long-term memories that last overnight.
Simple mathematical reasoning shows that the large amount of synaptic turnover seen in many parts of the brain is in fact optimal for memory retention.

A pentameric channel-receptor was studied by combining allosteric mutations, electrophysiology, fluorescent reporters and normal mode analysis, to dissect the long-range allosteric couplings specifically involved in its pre-activation and activation.
COVID-19 severity, rather than sex or age, predicts SARS-CoV-2 kinetics, and SARS-CoV-2 viral load from lower respiratory tract specimens may predict severe disease days before clinical deterioration for COVID-19 patients.

Serial-section electron microscopy uncovers the intricate neural network of the bumblebee central complex, revealing highly conserved projection patterns as well as novel circuit elements potentially unique to bees.
Genetic and biochemical analyses reveal that two stem-cell-specific microRNAs control stem cell fate decisions between pluripotency and differentiation through repressing Ago2, a key component of the microRNA machinery.
An insect digestive enzyme metabolizes a plant defense compound and thereby modulates herbivore performance and host plant choice, which in turn may alter plant defense evolution in nature.
