Stochastic models able to reproduce both incidence and seroprevalence data for Zika outbreaks in the Pacific Islands estimate that the basic reproduction number (R0) is between 1.5 and 4.1.
A method to assess the risk of self-sustained HIV transmission in heterosexuals from phylogenetic and epidemiological data is developed and, when applied to the Swiss HIV epidemic, shows that this risk is negligibly small for Switzerland.
Variable petal number in Cardamine hirsuta is explained by regulatory changes in the MADS-box gene APETALA1 that relaxed its epistasis over mapped QTL in the C. hirsuta genome.
The human immunodeficiency virus HIV-1 primarily spreads between cells using a method called cell-to-cell infection, suggesting that this process may be a target for anti-viral drugs.
Key numbers about the biology of the SARS-CoV-2 virus and the infection of a single human host by the virus have been compiled from the peer-reviewed literature.
A reanalysis of the stochastic model of organelle production (Mukherji and O'Shea, 2014) suggests that this model requires significant further discussion.
During early embryogenesis of the sea urchin, asymmetrical positioning of the dorsal/ventral organizer relies upon the suppression of organizer activities in dorsal blastomeres by the Hbox12 homeodomain-containing repressor.
Floral scent and nectar are highly variable in natural populations and both traits can influence outcrossing rates differently for different pollinators and increase future herbivory.
Heterogeneity in exposure to malaria vectors, including sporozoite-infected mosquitoes, contributes to the variation in human infection risk and amplifies the local transmission potential.
The ability to adjust body size in response to diet is greater in Drosophila females than males because of a sex difference in the nutrient-dependent regulation of the insulin pathway.
