Humans and chimpanzees share almost all their genes. Despite this, our brains have developed in different ways. Researchers at Lund University in Sweden have now shown that a viral pandemic dating back several million years is likely to be part of the explanation.

New marker panel and free web tool help track stem cells as they develop

How can the identity of pluripotent stem cells be determined more reliably during their differentiation? Researchers from the IUF—Leibniz Research Institute for Environmental Medicine and Heinrich Heine University Duesseldorf have systematically validated marker genes for this pu

Paleolithic human DNA reveals east-west connections across Ice Age Europe

More than 30,000 years ago, people associated with one of Europe's major Paleolithic cultures (the Gravettian) were more interconnected than previously thought. An international research team led by the University of Vienna has uncovered new genetic evidence of long-distance conn

Dental implants can hijack your immune system, scientists discover

Researchers have uncovered a surprising reason dental implant infections often resist antibiotics: the implants themselves can contribute to the problem. Bacteria corrode titanium implants, releasing microscopic particles that hijack immune cells, trigger destructive inflammation
