A mathematical model of blood-stage infection with Plasmodium falciparum malaria capturing the sexual stage of the parasite life-cycle is validated against human data, providing new insight into human-to-mosquito transmission.
Stochastic tuning of gene expression could be a common mechanism through which eukaryotic cells adapt to challenging external environments, potentially including survival of infectious organisms within the host and adaptation of cancer cells to chemotherapy.
Natural step-to-step variations show how human running is stabilized, underscoring the importance of center of mass control and showing how humans run without falling despite muscle noise and uneven terrain.
During human running, the soleus muscle was found to operate as work generator under optimal conditions for work production (high force-length potential and enthalpy efficiency) while the vastus lateralis promoted tendon energy storage and economical force generation (high force-length-velocity potential).
During centrosome maturation, pericentrin is delivered to the centrosome co-translationally by a microtubule- and dynein-dependent process, as pericentrin mRNA is undergoing active translation near the centrosome.
In fruit flies, maternally deposited RNA-binding proteins are removed during the maternal-to-zygotic transition via a mechanism of translational upregulation of Kondo, the key E2 enzyme, at egg activation.
