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.
