BBC News - Trojan-horse therapy 'completely eliminates' cancer in mice

BBC News - Trojan-horse therapy 'completely eliminates' cancer in mice: After chemotherapy or radiotherapy is used to treat cancer, there is damage to the tissue. This causes a surge in white blood cells, which swamp the area to help repair the damage.

"We're surfing that wave to get as many white blood cells to deliver tumour-busting viruses into the heart of a tumour," said Prof Lewis.

Her team takes blood samples and extract macrophages, a part of the immune system which normally attacks foreign invaders. These are mixed with a virus which, just like HIV, avoids being attacked and instead becomes a passenger in the white blood cell.

Human Evolution Enters an Exciting New Phase | Wired Science | Wired.com

Human Evolution Enters an Exciting New Phase | Wired Science | Wired.com: In the most massive study of genetic variation yet, researchers estimated the age of more than one million variants, or changes to our DNA code, found across human populations. The vast majority proved to be quite young. The chronologies tell a story of evolutionary dynamics in recent human history, a period characterized by both narrow reproductive bottlenecks and sudden, enormous population growth.
