Twitter has suspended the account of MeTooSTEM founder BethAnn McLaughlin after allegations emerged that the former Vanderbilt University neuroscientist fabricated the Twitter account of an apparently nonexistent female Native American anthropologist at Arizona State University who had claimed to be an anonymous victim of sexual harassment by a Harvard professor.
Scientists summarize the regulatory factors and downstream targets of F-box protein 22 (FBXO22) in cancers, discuss its functions in tumorigenesis, and further highlight the alteration of FBXO22 expression in a variety of human malignancies.

Researchers used CRISPR-Cas9 gene targeting to generate a library of 3D organotypic skin tissues that selectively differed in their capacity to produce glycan structures on the main types of N- and O-linked glycoproteins and glycolipids. This tissue library revealed distinct changes in skin formation associated with a loss of features for all tested glycoconjugates.
