Luke Tanner, 7, gets vaccinated for measles at a clinic near Swansea, Wales, in April. Wales is at the center of a measles outbreak that has been linked to one death.
Great Britain is in the midst of a measles epidemic, one that public health officials say is the result of parents refusing to vaccinate their children after a safety scare that was later proved to be fraudulent.
More than 1,200 people have come down with measles so far this year, following nearly 2,000 cases in 2012. Many of the cases have been in Wales.

The funguslike organism Phytophthora infestans causes potato leaves to decay and tubers to rot.

Sure, scientists have known for a while that a funguslike organism called Phytophthora infestans was responsible for the potato blight that plagued Ireland starting in the 1840s. But there are many different strains of the pathogen that cause the disease, and scientists have finally discovered the one that triggered the Great Famine.
