Evolutionary graph theory solves the longstanding puzzle of why diverse infectious diseases and cancers show similar (approximately lognormal) distributions of their incubation periods.

Pathogen natural history, epidemiological knowledge, human behavior and epidemic progression determine whether symptom screening and questionnaires are effective barriers to geographic spread of infection by travelers.

Control of COVID-19 will require strong case finding and isolation of exposed individuals because transmission can occur days prior to symptom onset.

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.

Despite the virus' error prone polymerase, influenza virus antigenic evolution is rare, even in previously immune hosts, virus replication occurs before producing new antibodies.

A novel synthetic DNA cassette of CTCF-binding sites combined with the drug-controllable induction system of heterochromatin enabled switchable blocking of chromatin conformation and gene-enhancer interaction.

A lack of ADAM10-mediated shedding increases prion protein levels at the plasma membrane and promotes the generation of pathological prion proteins, which accelerates prion disease in mice.

Cryo-EM studies reveal that incubation with ATP produces conformational intermediates of E. coli ATP synthase, in which the ε subunit is no longer in its autoinhibitory conformation.

Upon detecting a fatal infection using chemical cues, ants puncture the cuticle of sick brood and inject antimicrobial poison that disrupts the pathogen's life cycle and prevents it from reproducing, thus protecting the colony from disease.

Stimuli signaling reward availability potentiate and control relapse for up to 300 days of abstinence following cocaine, but not food, self-administration in rats.
