Think your DNA is all human? Think again. And a new discovery suggests it's even less human than scientists previously thought.

Female orphan chimpanzee are cared for at the Sanaga-Yong Chimpanzee Rescue Center. Understanding the origins of emerging diseases - as well as more established disease agents -- is critical to gauge future human infection risks and find new treatment and prevention approaches. This holds true for malaria, which kills more than 500,000 people a year. Symptoms, including severe anemia, pregnancy-associated malaria, and cerebral malaria, have been linked to the parasite's ability to cause infected red blood cells to bind to the inner lining of blood vessels.

In eLife today (22 March), Wellcome Trust Sanger Institute scientists show how the parasite responsible for the neglected tropical disease Black Fever (visceral leishmaniasis) can become resistant to drug treatment. Studying the whole genomes of more than 200 samples of Leishmania donovani revealed that the addition of just two bases of DNA to a gene known as LdAQP1 stops the parasite from absorbing antimonial drugs.

The cost of treating hepatitis C virus (HCV) could be cut up to 50 percent if mathematical models are used to predict when patients can safely stop taking direct-acting antiviral (DAA) medication, according to a new study by researchers at Loyola University Health System and Loyola University Chicago.
