A new analysis of a medieval cesspit in the Christian quarter of the old city of Jerusalem has revealed the presence of a number of ancient parasite eggs, providing a window into the nature and spread of infectious diseases in the Middle East during the 15th century. Researchers found evidence of six species of intestinal parasites in the over 500-year-old latrine. These included large quantities of roundworm and whipworm, both spread by fecal contamination of food and thought to be endemic to the region dating back to human evolution out of Africa.

Engineers at the University of California, Berkeley, are developing a new type of bandage that does far more than stanch the bleeding from a paper cut or scraped knee. Thanks to advances in flexible electronics, the researchers, in collaboration with colleagues at UC San Francisco, have created a new "smart bandage" that uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes - and while recovery is still possible.
