This I first posted on June 24, 2004 on www.jregrassroots.org, then republished on August 23, 2004 on Science And Politics. What do you think? Was I too rosy-eyed? Prophetic? In the beginning there were grunts, tom-tom drums, smoke signals, and the guy on the horse riding from village to village…

. This is a post intwo parts - the second being a reaction to the responses that the first one engendered. They may be a little rambling, especially the first one, but I still think that there is quite a lot there to comment on. Great Men and Science Education - Part 1 There is an interesting…

This is so basic that I even teach it in Intro Bio: Wherever the master clock may be located (SCN, pineal or retina) in any particular species, its main function is to coordinate the timing of peripheral circadian clocks which are found in every single cell in the body.

This post was a response to a decent (though not too exciting) study and the horrible media reporting on it. As the blogosphere focused on the press releases, I decided to look at the paper itself and see what it really says. It was first posted on August 09, 2005. Under the fold... I saw this…

I often ask you to read several posts in succession and make your own connections. Here's a line up of some old and some new posts about the history, current state (and cultural battle) and possible future of the institution of marriage: First off, Lance Mannion wrote a couple of days ago on…

This post, originally published on January 16, 2005, was modified from one of my written prelims questions from early 2000. EVOLUTIONARY PHYSIOLOGY OF BIOLOGICAL CLOCKS "Circadian clocks allow organisms to predict, instead of merely react to, cyclic (predictable) changes in the environment". A…

Today is the 150th birthday of Nikola Tesla. Here is an attempt to put in one place as much as can be found about the celebrations of his birthday and birth-year, the information about Tesla, the mentions in the media and on blogs, etc. I will keep updating this post throughout the day so,…

Many of us on SB are having problems with Movable Type today. Some of us can post OK, some can post only very short posts with no links and/or no mention of dr*gs etc. Others cannot post at all. This is a test to see if I can post anything. I'll try to post The Synapse late tonight or early in…
