Horus was the ancient Egyptian sky god who was usually depicted as a falcon, most likely a lanner or peregrine falcon. His right eye was associated with the sun Ra. The eye symbol represents the marking around the eye of the falcon, including the “teardrop” marking sometimes found below the eye.
Where viruses and bacteria cause cancer Strictly speaking, cancer is not contagious. But a fair number of cancers are clearly caused by viral or bacterial infections: lymphomas can be triggered by the Epstein-Barr virus, which also causes mononucleosis. Liver cancers can be caused by Hepatitis B and C. Cervical cancers can be caused by human papillomavirus, the major reason behind the development of a vaccine against it. For some of these cancers, nearly 100% of the cases have an infectious link—when researchers check to see if a virus or bacterium is working in the tumor or has left signs of its presence in a patient’s blood, the answer is nearly always yes. A new paper in The Lancet takes a look at the very best data on the prevalence of infection-caused cancers and comes up with some striking numbers. Overall, they estimate that 16% of cancer cases worldwide in 2008 had an infectious cause—2 million out of 12.7 million. Until recently cancers were seen as lifestyle and genetic diseases, brought on by exposure to carcinogens or a mutated gene. Recent studies are linking microbes to many different kinds of cancers. Participants will discuss not only how infection with specific pathogens causes cancers but also how disruptions in the human microbiome can also cause disease.
