Focus — UV Radiation and Skin Cancer: The Science Behind Age Restrictions for Tanning Beds

Every year, millions of people climb, in various states of undress, into warm, glowing tanning beds, where, during a typical 2- to 15-minute session, they absorb a controlled dose of ultraviolet (UV) radiation at an intensity of up to two to three times stronger than the sunlight striking the equator at noon.

PodcastMigration and Climate Change, with Jon Barnett and Celia McMichael

But, for the first time in our history, human beings are migrating because of climate change, for which we, ourselves, are partly responsible. In this month’s Researcher’s Perspective podcast, Celia McMichael, Ph.D., and Jon Barnett, Ph.D., discuss climate-related migration in the present day and the way it may look in the future.

Featured commentaries, reviews, and research this month include:

• Short-term Associations of PM2.5 Constituents and Hospitalizations

• Selective Pressure of Antibiotic Pollution on Bacteria Important to Public Health

• Human Neural Crest Cell Migration Assay for Developmental Toxicants

• DEHP, Adipogenesis, and Fertility in Mice
