Jan 29, 2014 — When you hear the words bubonic plague, Black Death usually comes to mind. But the first plague pandemic happened 800 years earlier, when the Justinian plague wiped out nearly a quarter of the world's population. Scientists have decoded the bacteria responsible, which have roots in China.
Jan 23, 2014 — Dogs can catch a strange type of cancer through sex. Now scientists have decoded the DNA of the tumor and found that the cancer cells are a living fossil of an ancient dog that lived thousands of years ago. This cancer doesn't affect people, but the findings may offer insights into how tumors fool the human immune system.
Dec 25, 2013 — Scientists have found a gene that helps to explain why Mexicans are prone to Type 2 diabetes. The disease gene, like many others we humans carry, dates back to the time when humans and Neanderthals had sex thousands of years ago.
Sep 20, 2013 — Since emerging last year in the Middle East, a mysterious virus has infected at least 132 people and killed 58. But it's still unknown how people get infected. A genetic analysis now suggests that animals may have repeatedly infected people with the deadly virus.
Aug 7, 2013 — A special committee that includes two members of the Lacks family will review scientists' applications for access to the genetic sequence of cells derived from a tumor that killed Henrietta Lacks. The cells are among the most widely used in research.
Jul 16, 2013 — Geneticists, pharmacologist and mathematicians combine their powers to answer one of the most vexing questions in modern oncology: Why don't anti-cancer drugs always work?
Jun 14, 2013 — Looking for clues to to modern-day leprosy, scientists dig up a 500-year-old mass grave and scan for ancient strains of bacteria in human remains. They find that the bacteria that cause leprosy haven't changed, humans have.
May 22, 2013 — A plant scientist at Mars Inc. has appealed to the world's biggest life sciences companies to help him — by sharing what they already know about 100 crops that could provide better nutrition in Africa. But can the kings of agricultural intellectual property get onboard with open source agricultural information for Africa?
Dec 10, 2012 — About 10 years ago, some nasty bacteria became impervious to some common classes of antibiotics. Scientists have sequenced genome samples of this superbug from all over the world. The results helped them figured out how it emerged in the U.S. and then moved to Europe, Australia and Asia.
Dec 3, 2012 — Technology now exists that makes it possible for doctors to decipher the entire genetic code of a newborn. Should it be done? What about fetuses in the womb? That's now a possibility, and it's stirring intense debate.
