Study co-author Dr. Elise Didion writes, “It makes sense… We find the highest transmission rates of West Nile virus during droughts because mosquitoes may use blood meals to replace the water they lose.”

Researchers followed the status of more than 27,000 women after their breast cancer surgery and found that 13% failed to have a mammogram within one year of their procedure. At the five-year mark, the percentage of women who had not had a mammogram in the last year rose to 19% and only 50% had undergone annual mammograms in the preceding half-decade. Lead researcher Dr. Kathryn Ruddy writes, “The use of regular mammograms to detect a return of breast cancer before ...
