The Most Interesting Scientist in the World: George M. Church

  • Mind Boggling Breadth and Significance of Scientific Publications
  • Serial Entrepreneur and Science Advisor to Many Companies
  • Radical Advocate of Total Openness for Personal Genomics

While seeing for the umpteenth time a Dos Equis beer commercial featuring The Most Interesting Man in the World, I was suddenly inspired to write a blog about The Most Interesting Scientist in the World. After scrolling and polling my memory to decide who that would be, it was an easy decision to pick George M. Church, professor of genetics at Harvard. As I’ll briefly highlight herein, Prof. Church’s contributions continually span a mind boggling spectrum of science that cuts across academic theory, ground breaking “how to” methods, serial entrepreneurship, and—perhaps most importantly—radical openness for personal genomics.

We’re Celebrating Click Chemistry In Honor of National DNA Day

  • The Verbification of Click Chemistry 
  • Old Chemistry Morphs into New Applications for DNA and RNA  
  • Amazingly, Phosphorus in DNA and RNA is not Needed for Function 

This post comes only two days after National DNA Day 2015 on April 25th so it’s apropos to feature DNA, but I’d also like to give a nod to the lesser recognized RNA, without which DNA would be akin to music notes in search of a melody.  If you’re a regular reader of this blog, you know my stance on this subject and so I digress…

So-called “Click Chemistry” is trending so “hot” that it has led to a phenomenon known as verbification, which is when a noun becomes a verb by virtue of popularity and linguistic convenience. So, just as Google has become to google for virtually everyone, Click has become to click for synthetic chemists and biotechnologists. Whether or not you’re already familiar with Clicking, I hope to provide herein some interesting snippets about Click, its growing ubiquity, and how it has enabled synthesis of a completely novel, non-phosphorous linkage in DNA that nevertheless functions flawlessly in vivo—a stunning feat never before achieved that has intriguing implications about life. More on that later, but first some snippets about Click.

DNA’s Forgotten Discoverer: Swiss Scientist Friedrich Miescher 

  • Discovered in 1869 in Pus Cells from Bandages of Crimean War Soldiers
  • Miescher Named this New Matter Nuclein and Intuited that it Played a Fundamental Role in Heredity
  • This put the “N” in DNA—Deoxynucleic Acid
  • Children now Isolate DNA from Fruits & Vegetables in Elementary School 

Truth be told, what led me to writing this post was suddenly realizing one day that, although the vast majority of my professional career involves nucleic acids—and DNA in particular—I did not know anything about the discovery of DNA or its naming. My follow-on thoughts were that this was somewhat embarrassing for a blogger focused on nucleic acids, and should be remedied by some homework! This is also good timing since my mind is currently aflutter with all things DNA in anticipation of National DNA Day coming up on April 25. In the event that you recall my past commentary about the bias toward DNA, yes I am still supporting a National RNA Day to balance the ranks, but I digress…

In doing my so-called homework, I learned about Swiss scientist Friedrich Miescher’s life story and circumstances surrounding his discovery in the late 1860s of new matter that he named nuclein, which eventually became incorporated into the term nucleic acid. Those circumstances, including Miescher’s unusual source of nuclein, were quite interesting to me so I thought they’d be worth sharing in this post, which draws upon a lengthy article by Ralf Dahm, who has written extensively about Miescher, and has a website worth visiting.
