When landing, Pacific parrotlets exhibit stereotyped leg and wing dynamics regardless of perch diameter and texture, but foot and claw kinematics become surface-specific upon touchdown to successfully grasp the perch.

A new fossil sheds light on the evolution of an aquatic lifestyle in extinct reptiles and supports a close phylogenetic relationship between archosaurs (crocodiles, dinosaurs, birds, and kin) and turtles.

Hypersensitivity of cohesin-deficient cells to Wnt signaling is concomitant with beta catenin stabilization and offers promise that Wnt agonists could be therapeutically effective in cohesin mutant cancers.

In three different regions including the United States, China, and Africa, virus discoveries were strongly associated with GDP and land use, but were less likely to be associated with climate and biodiversity variables than at a global scale.

Epigenetic regulations in the smoking- and blood pressure-related pathways to the future risk of coronary heart disease may reveal novel pathways or therapeutic targets.

Flowers did bloom in the Early Jurassic.

The ERK8 kinase blocks the export of glycosyl-tranferases from the Golgi to the endoplasmic reticulum, and thus subsequent O-glycosylation of proteins that otherwise enhance cell motility and tissue invasion.

Patterns of cortical excitability changes reflect the degree of sleepiness in humans.

Olfactory sensory neurons have centrioles that are amplified in number and that migrate from the cell body to the end of the dendrite relatively slowly and in groups, becoming mature only after they reach their destination.

Serum antibodies induced by CoronaVac tended to decrease over time, even though vaccinated with the homologous booster dose, and Delta and Omicron variants may be able to more efficiently evade the antibodies with time.
