Derek Lowe brings us a paper on the problems in drug discovery
Here's a really interesting paper from consultants Jack Scannell and Jim Bosley in PLoS ONE, on the productivity crisis in drug discovery. Several things distinguish it: for one, it's not just another "whither the drug industry" think piece, of which we have plenty already. This one get[s] quantitative, attempting to figure out what the real problems are and to what degree each contribute.
As they finish up by saying, we have to realize what the "domains of validity" are for our models. Newtonian physics is a tremendously accurate model until you start looking at very small particles, or around very strong gravitational fields, or at things with speeds approaching that of light. Similarly, in drug discovery, we have areas that where our models (in vitro and in vivo) are fairly predictive and areas where they really aren't. We all know this, qualitatively, but it's time for everyone to understand just what a big deal it really is, and how hard it is to overcome. Thinking in these terms could make us value more the data that directly reflect on predictive value and model validity (read the paper for more on this).
Be sure to read the comments at the end of Dr Lowe's article.
For those who may not recognize the name, this is the Derek Lowe who is author of: Things I Won't Work With and Things I'm Glad I Don't Do. He has a gift for writing that conveys complicated concepts in a very readable and entertaining fashion.

Nature probably evolved it somewhere in some exotic species. Traditional and folk medicine may even point the way.
It certainly paid off big here, Nobel Prize big:

But better hurry because the ideas are going quick:

The medical research community has spent decades starving and driving the people away who would come up with and test legitimate theories for what is going on, preferring to instead check the "null hypothesis". Now we are facing the unsurprising consequence that medical research is just as unreliable as other fields that do that (psychology, sociology).

Another interesting aspect is that the substitution of pseudo-statistics for science has been implemented primarily under the umbrella of being "evidence-based".

I was drawn to his stuff via the "things I won't work with" topics, but stayed for the drug discovery information. His information (from what I can tell) is accurate and unbiased. He describes the world of drug discovery and manufacturing very clearly. His balanced view is appreciated.
That is all.

I'm another fan. His blog is great and the people posting comments are very well informed.

Another big fan (obviously, I'm the subby). Started reading him when I stumbled across Things I Won't Work With, moved over to Things I Won't Do, and now hit his blog daily.
Guy is a pretty good writer.
