The Prickle1 gene regulates the differentiation of frontal bone osteoblasts in a new animal model

A mechanically compromised skull can result from enlarged fontanelles and smaller frontal bones due to defective migration and differentiation of osteoblasts in the skull primordia (developing skull). The Wnt/Planar cell ...

Chandra and ALMA measure speed of sloshing gas in galaxy cluster

Almost all galaxy clusters experience mergers. While a merger takes place, a specific spiral pattern can often be observed in X-ray images. Such a spiral feature is due to the motion of the sloshing gas induced by a merger. ...
