The Science of Kissing

Sheril Kirshenbaum, a research scientist at the University of Texas, decided to put the kiss under a microscope. She recently spoke about why a kiss really is more than just a kiss.

Kissing is a great example of a balance between the nature and nurture we always talk about. We see similar behaviors across the animal kingdom. So there is something innate. It's also something we pick up, not just from family and friends but it’s also exported by Hollywood. It is part of the community you’re in and what you’ve been exposed to. Decades ago, anthropologists estimated that 90% of cultures across the world kiss. That was before the rise of the Internet and the frequency with which so many people travel around the world, so I suspect that percentage is even higher today.

Scientists reactivate cells from 28,000-year-old woolly mammoth

"I was so moved when I saw the cells stir," said 90-year-old study co-author Akira Iritani. "I'd been hoping for this for 20 years."

Yamagata et al.
Surprising Science
  • The team managed to stimulate nucleus-like structures to perform some biological processes, but not cell division.
  • Unless better technology and DNA samples emerge in the future, it's unlikely that scientists will be able to clone a woolly mammoth.
  • Still, studying the DNA of woolly mammoths provides valuable insights into the genetic adaptations that allowed them to survive in unique environments.

Believe in soulmates? You're more likely to 'ghost' romantic partners.

Does believing in true love make people act like jerks?

Sex & Relationships
  • Ghosting, or cutting off all contact suddenly with a romantic partner, is not nice.
  • Growth-oriented people (who think relationships are made, not born) do not appreciate it.
  • Destiny-oriented people (who believe in soulmates) are more likely to be okay with ghosting.
