DNA Analysis Reveals Four Distinct Giraffe Species

By Katherine Lindemann Researchers have long recognized only a single species of giraffe, thought to be made up of several subspecies. However, a research collaboration has now identified four distinct species. Conservation biologist Julian Fennessy of the Giraffe Conservation Foundation, geneticist Axel Janke of the Senckenberg Research Institute, and their colleagues collected and analyzed samples from giraffes across the African continent. Their results appear in the journal Current Biology. ResearchGate: When and why did you start genetically testing giraffes across Africa? Julian Fennessy: When I approached Axel Janke to help…

Solar-Powered Oxygen Saves Lives in Africa

By Neha Jain @lifesciexplore If you’ve ever stayed in a hospital, you might remember the oxygen delivery system mounted on the wall behind your bed or at your bedside. Many of us take these for granted, but in developing countries such as Uganda they are not easily available—and even when present, they are unreliable because power cuts are rife. Now, scientists have devised an innovative solution for delivering oxygen to children with severe pneumonia: harnessing solar energy to power oxygen delivery systems. “Ours is the first study to describe the…
