Primates are an order (Primates) of eutherian mammals characterized by a suite of derived traits associated with arboreal locomotion and enhanced sensory and cognitive capacities. Defining features include grasping extremities with opposable thumbs and, in many taxa, opposable great toes; nails instead of claws on most digits; a postorbital bar or plate; forward-facing orbits enabling stereoscopic vision; and a relatively enlarged brain, especially in regions mediating vision and complex behavior. The order encompasses strepsirrhines (lemurs, lorises), tarsiers, and haplorhine simians (monkeys and apes, including humans), and is a core model group in evolutionary biology, comparative anatomy, neurobiology, and behavioral ecology.
Researchers from the National University of Singapore (NUS) have developed CellScope, a high-performance single-cell analysis framework that uses manifold fitting to analyze single-cell RNA sequencing (scRNA-seq) data. This ...
