Fitting a mechanistic model to data from SARS-CoV-2 source-recipient pairs generates improved estimates of changes in infectiousness during infection, indicating substantial transmission shortly before symptom onset.
The smoking cessation drug varenicline (Chantix) and other weak base ligands reduce a4b2-type nicotinic receptor (a4b2R) upregulation through slow intracellular release due to selective trapping in acidic vesicles that contain a4b2Rs.
Citizen science camera trapping showing suburban and wild areas maintain similar levels of mammalian diversity and relative abundance, challenging conventional thoughts about the impacts of urbanization on wildlife.
A two-part neural network models reward-based training and provides a unified framework in which to study diverse computations that can be compared to electrophysiological recordings from behaving animals.
Test-and-release quarantine strategies for traced contacts of confirmed SARS-CoV-2 cases and returning travellers can reduce average quarantine durations while remaining as effective as 10 days of quarantine without testing.
