We have only known about Lyme disease since 1975, but now the discovery of an amber-encased 15-million-year-old tick has revealed that the bacteria that causes the disease has been around much, much longer than the human race. The discovery was made by George Poinar, Jr. from Oregon State University, and the findings were published in Historical Biology. Lyme disease is caused by the bacteria in the genus Borrelia, which uses ticks as… Read More

Drug-resistant bacteria annually sicken 2 million Americans and kill at least 23,000. A driving force behind this growing public health threat is the ability of bacteria to share genes that provide antibiotic resistance. Bacteria that naturally live in the soil have a vast collection of genes to fight off antibiotics, but they are much less likely to share these genes, a new study by researchers at Washington University School of Medicine in… Read More
