# The Mysteries Of Migraines
What do sensitivity to light, a craving for sweets and excessive yawning have in common? They’re all things that may let you know you’re about to have a migraine. Of course each person’s experience of this disease—which impacts an estimated 38 million people in the U.S.—can be very different. One person may be sensitive to light while another is sensitive to sound. Your pain may be sharp like a knife while your friend’s may be dull and pulsating. Or perhaps you don’t have any pain at all, but your vision gets temporarily hazy or wiggly. This week Ira is joined by two migraine experts, Elizabeth Loder, of Brigham and Women’s Hospital and Harvard Medical School, and Peter Goadsby, professor of neurology at the University of California San Francisco, who explain what’s going on in the brain of a migraineur to cause such disparate symptoms. Plus, why some treatments work for some and not others, from acupuncture and magnesium supplements, to a new FDA approved medication that goes straight to the source.
# How Do Galaxies Get Into Formation?
The Milky Way and distant galaxies are a mix of gas, dust, and stars. And while all of this is swirling in space, there is a structure to a galaxy that holds all of this cosmic dust in order. A group of researchers discovered a nearly 9,000 light year-long wave of “stellar nurseries”—star forming regions filled with gas and dust—running through the Milky Way, and could form part of the galaxy’s arm.
The study was published in the journal Nature. Astronomers Alyssa Goodman and Catherine Zucker, who are authors on that study, tell us what this star structure can tell us about the formation of our galaxy.
Plus, astrophysicist Sangeeta Malhotra talks about one of the oldest galaxies formed 680 million years after the big bang, and https://www.sciencefriday.com/segments/galaxy- formation/" target="new">the difference between these ancient galaxies and our own. Read more
