Tick-derived sequence variation in the fusion glycoprotein of Crimean-Congo hemorrhagic fever virus (CCHFV) drastically impairs infection of mammalian cells, suggesting that certain CCHFV strains undergo purifying selection in mammalian hosts.

Procedures were developed to perform mesoscale 2-photon Ca²⁺ imaging simultaneously from all of mouse dorsolateral neocortex, facilitating identification of widespread neural ensembles with activity related to diverse aspects of behavior.

Genetic and proteomic analyses reveal that the SPARK kinase, which is a regulator of key life-cycle transitions in the parasite Toxoplasma gondii, complexes with an elongin-like protein to regulate several important AGC-family kinases.

Parasites with pathogenic variant surface antigens are common in adult malaria patients with a naive immune status.

Genome dilution limits cell growth by modulating the activities, rather than the concentrations, of RNA polymerases and ribosomes, and is accompanied by changes in proteome composition.

Short-term interventions, including intermittent fasting, boosting cellular energy, and promoting beneficial gut bacteria, rejuvenate osteoprogenitors in aged animals and, when combined with localized Wnt, restore youthful bone healing.

Overexpression of hAC8 engages complex, coordinate adaptation 'circuity' that has evolved in mammalian cells to defend against stress that threatens health or life, and may be important for proper healing in disease states such as heart infarction or failure.

Single-cell RNA-sequencing, spatial genomics, and histological analyses reveal that cold-induced brown adipose neogenesis is a complex adaptive response to elevated metabolic demand involving dynamic interactions between recruited immune cells and a subpopulation of poised adipocyte progenitors.

The three-dimensional architecture of the genome in distinct cell types predicts genes and regulatory elements involved in cell function and disease.
