There's been a lot of talk recently about scieintific misinformaton on the internet. I started reminiscing about what things were like when I was growing up. I remember when I learned about DNA and when I first heard about black holes.
Then I remembered how excited I was when I first heard about the properties of thiotimoline from a well-known biochemist (Asimov, 1948). I can't say for sure that this tilted me toward choosing a career in biochemistry but it certainly played a role.
Some of you may not be familiar with thiotimoline. Here's the most important characteristic of this amazing molecule as reported in the original paper.
