Scientists raid DNA to explore Vikings’ genetic roots

In popular imagination, Vikings were robust, flaxen-haired Scandinavian warriors who plundered the coastlines of northern Europe in sleek wooden battleships. But despite ancient sagas that celebrate seafaring adventurers with complex lineages, there remains a persistent, and pernicious, modern myth that Vikings were a distinctive ethnic or regional group of people with a “pure” genetic bloodline. Like the iconic “Viking” helmet, it’s a fiction that arose in the simmering nationalist movements of late 19th-century Europe. Yet it remains celebrated today among various white supremacist groups that use the supposed superiority of the Vikings as a way to justify hate, perpetuating the stereotype along the way.

Drexel Medicine Researchers Develop New Technology to Target DNA Damage Repair in Cancer Patients

DNA break

A team of Drexel University College of Medicine researchers is advancing a way to destroy cancer cells exploiting “synthetic lethality,” which is caused by deficiency in the DNA damage response (DDR) pathway. Synthetic lethality occurs when deficiencies in each of any two genes can be tolerated by the cell but the combination of these two deficiencies is lethal.
