The Omicron variant evades vaccine-induced neutralization but also fails to form syncytia, shows reduced replication in human lung cells and preferentially uses a TMPRSS2-independent cell entry pathway, which may contribute to enhanced replication in cells of the upper airway. Altered fusion and cell entry characteristics are linked to distinct regions of the Omicron spike protein.

Clare Turnbull and colleagues identify three new risk loci for testicular germ cell cancer. The newly discovered risk variants reside near the telomere regulator genes TERT and ATF7IP and the sex determination gene DMRT1.
