My genes don’t fit! Living in a salt saturated society. Matthew Bailey

Published by:

Our biology is currently out of sync with our environment. By making connections between past and present, Matthew sets out how we came to be in such a predicament, and the consequences for our health.

This talk was delivered at Edinburgh’s iconic Central Hall on Thursday, February 18th 2016 and was a part of series of talks given at the TEDxUniversityofEdinburgh 2016 Conference.

Dr Matthew Bailey is the Director of the Centre for Cardiovascular Science at the University of Edinburgh. He completed his PhD in London, post-doctoral training in Saclay (France) and has worked at Yale. Along the way, Matthew has been picking apart the workings of the kidney, blood pressure, and most recently the role of salt in human physiology.

TIL: Female Lions Are Attracted to Black Manes. National Geographic Video

It turns out the search for a tall, dark, and handsome mate isn’t limited to dating websites—or even to humans. A lion’s mane will change color in accordance with its nutrition level and overall well-being; a male lion with a darker mane tends to be healthier and have higher testosterone levels. As a result, lionesses find lions with darker manes more attractive, according to biologist and National Geographic grantee Craig Packer.

In one study, a graduate student working with Packer used stuffed toy lions with various mane colors to test female preference. That study found that 90 percent of the time lionesses chose to approach the replicas with darker manes. Nature is so typical—boring, good-looking dudes ruining it for the rest of us. Maybe the remaining 10 percent of lionesses are more interested in a potential mate’s personality qualities? In this week’s “Today I Learned,” Packer explains a bit more about this phenomenon.
