Just a quick post this morning as I am performing my professional responsibility to our nation’s health research agency. In yesterday’s issue of USA Today (which I only read on the iPhone app or when staying at a hotel that gives it to us free), Donna Leinwand wrote about a currently legal substitute for marijuana…

Have you ever taken one of the now-over-the-counter heartburn relief remedies like Tagamet, Zantac, or Pepcid? How about the beta-blocker atenolol (Tenormin) or metoprolol (Lopressor) for antihypertensive therapy, or the original less-selective beta-blocker propranolol (Inderal) for migraines, presentation anxiety or stage fright? If you answered yes to either question, you owe a debt of gratitude…

In our last post, we discussed a recent USPTO ruling that rejected a claim of the Pfizer patent on the erectile dysfunction drug, sildenafil (Viagra®), to a novel oral treatment for the disorder. The patent appeals panel ruled that the existence of horny goat weed, a traditional Chinese medicine used orally for impotence, was grounds…

Last week in Stockholm (and Oslo), the 2009 Nobel Prize winners were gloriously hosted while giving their lectures and receiving their medals and diplomas. In Chemistry this year, the Nobel was shared by Venkatraman Ramakrishnan, Thomas A Steitz, and Ada E Yonath for their studies on the structure and function of the ribosome, a remarkable…

Welcome visitors coming from a recommendation by Dr Carmen Drahl at C&ENtral Science, the blog of the American Chemical Society’s Chemical & Engineering News (C&EN): Terra Sig has a fantastic post about the chemistry prize. The money quote: “If I see electrons being pushed around, it’s chemistry.” Thank you for the kind words, Dr Drahl.…

I know that we have been very fortunate to attract a few new readers over the last year or so. For those, and as a reminder to others, I wanted to focus on some of my major blog influences. One of these is Derek Lowe, an early science blogger who is perhaps the only pharmaceutical…

I love it when new readers stumble upon old posts. Such was the case when I received the following delightful comment from Seattle-based psychologist, Dr Gary Grenell, on my April 2008 post about the passing of Dr Charlotte Tan, a pediatric cancer chemotherapy pioneer: I was probably in one of her earliest actionmycin-D trial groups…

A recent discussion with some of my neuropharmacology colleagues led me to go back through the cobwebs and revisit the Terra Sig archives for posts on drugs of abuse. The following was my third post ever and the first on actual scientific substance (the first two were introductions: a hello post and an explanation of…

Welcome 4 March readers of The Daily Grail – please be sure to also click on the original post about the DMT article by my colleague, Laura Mariani. Thanks to Dave Munger & Co’s ResearchBlogging.org, I just found a fabulous neuroscience grad student blogger from Emory University: Laura E Mariani at Neurotypical? Doctor-to-be Mariani blogged…

Yes, this is what happens when two scientists stay home on Valentine’s evening. PharmGirl just fed me the story from CNN about the San Jose high school kid who died yesterday after being taken unconscious from his house on Thursday. The national and local stories indicate that “two pans containing hydrogen sulfide were found on…
