Personal Reflections On A 9/11 Hero (repost)

Here is why I will always remember. Originally posted on 11 September 2006 at Terra Sigillata on ScienceBlogs. Let me tell you about John Michael Griffin, Jr. Griff, as he was known in high school, was a friend of mine. Late in the first half of our lives, he stood up for me physically and philosophically, for being a science geek. John’s endorsement was the first time I was ever deemed cool for wanting to be a scientist. Griff...

Do you remember your PhD defense?

A new and already-dear friend is defending her doctoral dissertation tomorrow. I remembered that I had written a post awhile back on my feelings about my own defense, and how my perceptions at the time didn’t measure up to reality. The timing of this repost also coincides with the Diversity in Science Blog Carnival just posted at Neurotic Physiology, written by another remarkable woman scientist friend of mine, Scicurious. The...

Poppy seed tea can kill you (repost)

Almost exactly two years ago, I posted the following story at the ScienceBlogs home of Terra Sigillata. I was drawn to revisit this moving, tragic story yesterday after reading a post by organometallic chemist Sharon Neufeldt at I Can Has Science? entitled, Morphine, Heroin, and Lemon Poppy Seed Cake. In honor of Tom’s courage and the memory of his son, this repost is a fitting adjunct to Sharon’s essay. The following post...

Remembering Challenger…

This post appeared originally at the ScienceBlogs home of Terra Sigillata on 28 January 2007. It was a very cold morning in North Florida (in the teens/low 20s Fahrenheit) as I walked in to class during my second semester of graduate school. I vaguely recall some concerns about the launch of Challenger that morning because of the cold and I believe it was scrapped once before, this highly-touted launch of America’s first...

What’s the buzz?: Synthetic marijuana, K2, Spice, JWH-018

The topic of one of our most popular posts of all time has been the synthetic marijuana products containing JWH compounds, naphthoylindole cannabimimetics synthesized in the 1990s in the Clemson University laboratory of John Huffman. This post first appeared at the ScienceBlogs home of Terra Sigillata on 9 Feb 2010 and gives you some background on the active components of K2, Spice, and other products. My field of natural products...

Sharks don’t get cancer but do they get Salmonella poisoning???

This post appeared originally at the ScienceBlogs home of Terra Sigillata on 18 May 2007. I’m putting it up today to accompany a superb post by University of Hawai’i graduate student and science writer, Christie Wilcox, at Observations of a Nerd. Actually, sharks do get cancer but a 15-year-old book by William Lane led people to think otherwise, launching investigation of shark cartilage as a source of antiangiogenic,...
