Seven Questions….with Yours Truly

Last week, my SciBling Jason Goldman interviewed me for his blog. The questions were not so much about blogging, journalism, Open Access and PLoS (except a little bit at the end) but more about science – how I got into it, what are my grad school experiences, what I think about doing research on animals,…

Are Zombies nocturnal?

Blame ‘Night of the Living Dead’ for this, but many people mistakenly think that zombies are nocturnal, going around their business of walking around town with stilted gaits, looking for people whose brains they can eat, only at night. You think you are safe during the day? You are dangerously wrong! Zombies are on the…

Whenever I read a paper from Karl-Arne Stokkan’s lab, and I have read every one of them, no matter how dense the scientese language I always start imagining them running around the cold, dark Arctic, wielding enormous butterfly nets, looking for and catching reindeer (or ptarmigans, whichever animal the paper is about) to do their…

I am not the only one on ScienceBlogs.com to write about circadian rhythms, sleep and (non-visual) photoreception. Over the years, my SciBlings have written about these and related topics as well. Here is a sampler – go and dig for more on their blogs. Stimulant Improves Sleep Locked-In Syndrome Opioids and Sleep Disorders Home Testing…

Victor Bruce, a lecturer emeritus in biology at Princeton who conducted advanced studies for more than 25 years on the built-in cycles governing natural rhythms like the sleep-wake cycle, has died. He was 88. Bruce, who despite a background in engineering became drawn to biological studies, died Friday, May 29, at his home in Princeton…

If you ever glanced at the circadian literature, you have probably encountered the statement that “circadian rhythms are ubiquitous in living systems”. In all of my formal and informal writing I qualified that statement somewhat, stating something along the lines of “most organisms living on or near the Earth’s surface have circadian rhythms”. Why? In…

Most people are aware that social insects, like honeybees, have three “sexes”: queens, drones and workers. Drones are males. Their only job is to fly out and mate with the queen after which they drop dead. Female larvae fed ‘royal jelly’ emerge as queens. After mating, the young queen takes a bunch of workers with…

The Scientist special topic: Sleep

Nice four articles: The Gears of the Sleep Clock By Allan Pack: When people have trouble sleeping–such as, in extreme cases, shift workers–those problems are not always rooted in disturbances in circadian rhythm, argues the University of Pennsylvania’s ALLAN PACK. Instead, his studies of sleep have shown that the master clock is only one player…

Daylight Saving Time

Yup, it’s tonight. If you were around here a few months ago, the day after the Fall Back day, you probably read this post. Disregarding the debate over rhetoric of science, that is probably my best, most detailed explanation for what happens to our bodies on those too strange days of the year – Spring…

Meetings I’d like to go to….Part III

The 2009 Gordon Conference on Chronobiology is all molecular, and it is tough to get in anyway. It would be nice to go, but I don’t see how I can get invited and/or funded.
