My scientific specialty is chronobiology (circadian rhythms and photoperiodism), with additional interests in comparative physiology, animal behavior and evolution. I am not an MD so I cannot diagnose and treat your sleep problems. As well as writing this blog, I am also the Online Discussion Expert for PLoS. This is a personal blog and opinions within it in no way reflect the policies of PLoS. You can contact me at: Coturnix@gmail.com

This is a long post from January 23, 2005, trying to tie in Creationism and conservatism through psychology: I always loved animals and always loved science. I read the kids' science and nature books and encyclopedias, as well as adult stuff, like huge volumes about animals e.g., "The Life of…

Since my move here to SEED scienceblogs, I made a mistake of assuming, quite wrongly, that most of my visitors are aslo science bloggers (or people interested in science) who, almost by definition, regularly read all of the other SEED sciencebloggers as well. I forgot that some of the readers are…

Sawing The ZZZZZs: Getting Old Needn't Keep You Awake, Geriatricians Say: "Patients must be educated on normal sleep-related changes but also made aware that sleep problems are not a part of normal aging." Again we have the problem with the use of the word "normal"! Fragmentation of sleep in old…

The obligatory reading of the day: That right-wing logic: OK, so I laughed at this one. Because this is what passes for logic not just among rural hicks, but nearly the entire right wing in this country.

Norse cult gains among inmates: A pagan religion that some experts say can be interpreted as encouraging violence is gaining popularity among prison inmates, one of whom is scheduled to be executed this week for killing a fellow prisoner at the foot of an altar. Michael Lenz is scheduled to die…

Including screwing with the people who touch themselves for a charitable cause: "Overall I think a well-intentioned event has been hijacked by a corporation who don't really care if we have good sex and enjoy masturbation, but just want more viewing figures.

My son's birthday is next week. He wants (and we agree) a laptop. He is, surprisingly for a man of his brilliance, a PC guy. Good graphics and sound are very important for the stuff he does (making Flash movies, gaming, etc). What should we get him? You know we are dirt poor, so steer away from…

Phil Plait has an excellent post: Wealth of Science: Then the author said something that literally startled me: "Scientists, till recently at least, effectively donated the wealth they created." He's absolutely right. Again, wealth is not the same as money. Scientists take a relatively small…

Inspired by RPM of Evolgen, I ask, how many people in your school/University, or town, or state, are blogging, especially about science? First, I don't know of anyone from my University who blog privately, though you can probably search the MSNBlogs etc. for schools and locales. But, folks at…
