Analysis of centuries-old DNA from both victims and survivors of the Black Death has identified key genetic differences that helped people survive the plague. 9News

Researchers analyzed DNA from the remains of people extracted from plague pits, which were used for mass burials in 1348 and 1349 amid a plague outbreak in London.

"We are the descendants of those that survived past pandemics ... and understanding the evolutionary mechanisms that contributed to our survival is not only important from a scientific viewpoint, but can also inform on the mechanisms and genetic determinants of present-day susceptibility to disease," study co-author Luis Barreiro, a professor of genetic medicine at the University of Chicago, said via email.

Don't blame doctors alone for Medicare fraud and waste. The system is at faultThe Medicare scheme turns 40 next year and when it was designed the burden of disease was very different to what it is now, writes Sophie Scott. They are the system. Thanks both sophiescott2 and Karen Price for this. The system is broken not the Doctors using the system. Rebates have been reduced to an unusable amount. I am an organised person but when getting to GP there is always more to discuss. Allergies and intolerances need checking. 🤔🧐
