As soon as the calendar turns over to October (and sometimes even before!) retail and media outlets remind us Halloween is coming. Wherever we look, it seems to be costumes, candy and scary movies abound. But did you know that many of the things that come to mind when we think of Halloween have a tie to physiology?

Check out some of our past Halloween-themed posts to learn more about:

• the (not so) monstrous mutations humans have experienced over the millennia;
• how certain creepy, crawly critters have contributed to science;
• how our bodies respond to fear, dark, stormy nights and haunted houses; and
• what to do in the event of a vampire attack.

Enjoy these vintage posts and have a safe and happy Halloween!
