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

You should check out all of my SiBlings' Friday Blogging practices, then come back here for a new edition of Friday Weird Sex Blogging. Last week you saw an example of a corkscrew penis. But that is not the only one of a kind. See more under the fold (first posted on July 14, 2006)... Some birds…

What?.... There is a slang phrase in Serbo-Croatian that means "doing nothing; being idle; wasting time", and it is "hladiti jaja", which means "cooling (one's) balls". So, if you see a guy just sitting there, clutching a beer bottle and gazing into the distance, you may ask him "Hey, man, whatcha…

According to the referrers pages of my Sitemeter, a lot of you are excited by strange penises, strange penises, strange penises and strange penises (or something like it). So, today we have to move to a different topic, traffic-be-damned, for those without phallic fixations. So, read on (first…

I love getting alumni letters from NCSU - I get reminded over and over again how cool research gets done there all the time. In this issue, for instance: NC State Study Finds Genes Important to Sleep: For many animals, sleep is a risk: foraging for food, mingling with mates and guarding against…

Well, this was a busy week for sure (and not just yesterday's telecom outage that affected PLoS all day!). There was cleaning, and shopping, and cooking, and gathering/borrowing extra tables, chairs, plates and silverware, for that One Big Night of the year at our house - the Passover dinner. Last…

There is a vitality, a life force, an energy, a quickening, that is translated through you into action, and because there is only one of you in all time, this expression is unique. - Martha Graham

The Bay Area experienced telecoms trauma overnight. Rumors of main switch outages, fiber optic cables being cut and telephone coverage being suspended, abound. We hear that the fiber optic cable is the most likely culprit. We're trying to figure out how long it might take for these big picture…

The Secret To Chimp Strength: February's brutal chimpanzee attack, during which a pet chimp inflicted devastating injuries on a Connecticut woman, was a stark reminder that chimps are much stronger than humans--as much as four-times stronger, some researchers believe. But what is it that makes our…

The Associated Press is, I hear, not stupid. So, the only explanation for this is that they are suicidal (but that is not new, of course). And, since it is them who are clogging the system, ruining the newspapers and threatening the Web, perhaps they should be persuaded to just shut down for good.…

He didn't come out of my belly, but my God, I've made his bones, because I've attended to every meal, and how he sleeps, and the fact that he swims like a fish because I took him to the ocean. I'm so proud of all those things. But he is my biggest pride. - John Lennon

In TIME, a couple of days ago - How Obama Is Using the Science of Change: Two weeks before Election Day, Barack Obama's campaign was mobilizing millions of supporters; it was a bit late to start rewriting get-out-the-vote (GOTV) scripts. "BUT, BUT, BUT," deputy field director Mike Moffo wrote to…

Lifeless Cells Ensure Sharp Vision: Seemingly dead cells perform a surprising task in the lens of a fish eye. Every morning and evening they change the lens's capacity to refract light in order to enhance color perception during the day and night vision when it's dark. This is shown in new…

Humor is, I think, the subtlest and chanciest of literary forms. It is surely not accidental that there are a thousand novelists, essayists, poets or journalists for each humorist. It is a long, long time between James Thurbers. - Leo C. Rosten
