‘Why Do People Go Bald’ Video Tackles Hair Loss Head On

Damn you, genetic variant on chromosome 20!

A new SciShow video that explains why people go bald says the genetic variant makes men seven times more likely to lose their hair, but doesn’t appear to affect women.

Abnormalities in chromosome 20 have been linked to serious diseases, such as blood cancers. But in 2008, researchers found that regions on the chromosome appear to be associated with baldness.

The video offers other fun tidbits about failing follicles, but may still leave sufferers at a loss. That’s because science has yet to cure baldness, which narrator Hank Green calls “the holy grail of beauty.”

Statistics tell us that, at some point, we’ll all have to deal with thinning or disappearing locks. Two-thirds of American men have “some degree of appreciable hair loss” by age 35, and 85 percent have “significantly thinning hair” by age 50, according to a consumer group called the American Hair Loss Association. Forty percent of women experience “visible hair loss” by age 40, the American Academy of Dermatology says.

Science Can Change the World

We live in an age of extraordinary progress: never in time have we lived longer, in better health. In the past two decades nearly one billion people were taken out of extreme poverty and several severe diseases have been eliminated in many parts of the world, like malaria in over one hundred countries. We have more computer power in our smartphone than in the Apollo 11 and we can reach billions of people instantly via the internet.

Nevertheless, the challenges we face in the decades ahead are many (just think about inequality, or climate change or the fact that still around 800 million people go to bed hungry every day), there is every reason to be positive. Why?

Well, much of the progress we made, has been made possible by science and technology: more notably by the ingenuity and perseverance of individual people, often scientists, whether they worked for themselves, for universities or for companies. Of course enabling progress isn’t the exclusive domain of scientists (not at all even) but I would like to take this opportunity to highlight their contribution and the way they frequently had to overcome hurdles, often driven by their curiosity, perseverance and desire to contribute to society.

Although many remain unknown to the public at large, they have had an enormous impact on the development of a healthier, more sustainable and prosperous society. Every day scientists around the world strive to provide answers to global challenges, going to great lengths and making huge personal sacrifices to solve the great challenges of our time.

Remember “The Jetsons” cartoon series? It portrayed technologies in the sixties that seemed magical at the time such as videophones, talking alarm clocks, flat screen TVs, a kind of internet connection and even robots to clean your house …. All are reality —> Read More
