从科学研究的角度看，所谓的“环境内分泌干扰物”，指的是一些可能干扰体内激素信号的化学物质，例如某些塑料添加剂（如双酚A，BPA）、工业污染物（邻苯二甲酸酯）或被称为“永久化学品”的物质（全氟和多氟烷基物质）。这些物质广泛存在于食品包装、日用品、工业材料或环境中，在实验研究和部分人群研究中显示出干扰激素信号的潜在能力，但不同研究之间的结果并不一致，且暴露水平、暴露时机与青春期指标之间的关系仍难以精确界定。
How much turbulence can an airplane bear? Every year, the question is asked and answered by a group of Air Force and NOAA pilots and researchers known as the hurricane hunters. The initiative began, unofficially, in 1943, when Lieutenant Colonel Joseph Duckworth flew into the eye of a hurricane near Galveston, Texas. Duckworth made his flight on a dare, but the programs have since taken on a more serious role: to report on hurricanes as they develop and to study their inner mechanics. Last year, Joshua Wadler, a hurricane hunter and a meteorologist at Embry-Riddle Aeronautical University, in Florida, went through the turbulence data from every NOAA hurricane flight since 2004, and two infamous ones from the nineteen-eighties. He measured how much each flight was thrown around along six axes of motion: roll, pitch, yaw, surge, sway, and heave. (The words alone can induce vertigo.) Then he made a list of the bumpiest flights ever recorded.
