In many parts of the war-torn East African nation, the charity is the only provider of healthcare ranging from basic medical supplies to major surgery. MSF has always been famous for being the last charity to pull out of war zones. But the organization said a combination of its staff being killed, kidnapped or attacked had become intolerable. Fifteen hundred medical staff will stop work. The expatriates among them will leave and the Somalis will lose their jobs.

British scientists say they uncovered important new information about the way cancers develop. They have identified 21 types of genetic change on mutation that underline the most common types of the illness. Professor Alexandrov  is a surgeon who was involved in study.

“We can actually start to see the very core changes we see in genes in the DNA of cancers and what that means is we can start to think about what actual processes are directly starting to damage the DNA. This is something we haven't really been able to do before.”
