Infectious organisms that become resistant to antibiotics are a serious threat to human society. They are also a natural part of evolution. In a new project, researchers at the University of Gothenburg are attempting to find substances that can slow the pace of evolution, in order to ensure that the drugs of today remain effective into the future.

A protein found in the saliva of ticks helps protect mice from developing Lyme disease, Yale researchers have discovered. The findings, published in the November 19 issue of Cell Host & Microbe, may spur development of a new vaccine against infection from Lyme disease, which is spread through tick bites.
