Editor's Selections: Properties of eyeliner, Rituals, Tales told by pottery, and Roman diets

Join Our Community of Science Lovers!

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American


The selection for this week covers the last two weeks:

  • We might not give much thought to eyeliner today, dismissing it as a beauty product that highlights and enhances the eye, but the ancient Egyptians had a different purpose for lining their eyes: preventing eye infections. At Body Horrors, Rebecca Kreston has the scoop on the antibacterial properties of kohl.

  • Rituals permeate our daily lives. Why do certain rituals persist over others? Eric Horow reports on a recent study at Peer Reviewed by My Neurons investigating how we evaluate the effectiveness of rituals.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
