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

FEST ended with a (excellent) keynote lecture by Lawrence Krauss:

One of the important questions in the study of circadian organization is the way multiple clocks in the body communicate with each other in order to produce unified rhythmic output. In the case of mammals, the two pacemakers are the left and the right suprachiasmatic nucleus (SCN). The tow nuclei…

Mighty Microbes: Bacteria Filaments Can Bundle Together And Move Objects 100,000 Times Bacterium's Body Weight: Researchers from The University of Arizona and Columbia University have discovered that tiny filaments on bacteria can bundle together and pull with forces far stronger than experts had…

The podcast of the radio interview with Derek Law and me about Open Access is now available online. Most of the show is in Italian, but if you cannot understand it, our interview is in English and it starts at the 22:07 minute point.

Yup, as soon as I land in Belgrade, I will be giving two lectures about Open Access and the Science Communication in the Age of Internet. The first one, this Tuesday at 11am, will be in the beautiful hall of the Museum of Contemporary Art in Belgrade, sponsored by the Serbian Museum Association…

Some more pictures.... Saturday dinner: Alessandro interviewed me for the newspapers: We were sitting on the edge of Adriatic: Then I gave another interview, this time about blogging (there will be no podcast - this material will be used for a written text):

The third post in the series on entrainment, first written on April 10, 2005, starts slowly to get into the meat of things...As always, clicking on the spider-clock icon will take you to the site of the original post. In the previous post, I introduced the concept of entrainment of circadian…

Professor Steve Steve went to FEST with me yesterday and made many friends (I told his story 50 times at least). Here he is with Lawrence Krauss: And I hope Mrs.Coturnix does not click on the "Read on...." button, as Professor Steve Steve is a well-known and certified babe magnet:

Here are some even better pictures from the panel:

The science blogging session yesterday was really fun. I am wearing headphones as everyone else was speaking Italian, so I listened to the simultaneous translation. The locals also listened to me via the interpreter:

Who can tell whether learning may not even weaken invention in a man that has great advantages from nature and birth; whether the weight and number of so many men's thoughts and actions may not suppress his own or hinder the motion and agitation of them, from which all invention arises; as heaping…

One of the assumptions in the study of circadian organization is that, at the level of molecules and cells, all vertebrate (and perhaps all animal) clocks work in roughly the same way. The diversity of circadian properties is understood to be a higher-level property of interacting multicelular and…

Not many people know that James Joyce spent 11 years in Trieste as a lecturer at the University. Now, his bronze statue still walks the bridge across the canal on Ponte Rossa:

I love how many dogs I saw roaming FEST and learning about science....

This is the second in a series of posts on the analysis of entrainment, originally written on April 10, 2005. The natural, endogenous period of circadian rhythms, as measured in constant conditions, is almost never exactly 24 hours. In the real world, however, the light-dark cycle provided by the…

Yes, that is Lawrence Krauss on the left....

Last night, Derek Law and I were taped for about 15 minutes for Radio3, about Open Access and the world of publishing:

Yesterday afternoon, Sely Costa and Derek Law did a fun session, where she pretended to be an unconcerned citizen and he tried to persuade her that OA is a good thing. It was a fun way to demonstrate how OA benefits everyone, not just researchers.

Clues To Ancestral Origin Of Placenta Emerge In Genetics Study: Researchers at the Stanford University School of Medicine have uncovered the first clues about the ancient origins of a mother's intricate lifeline to her unborn baby, the placenta, which delivers oxygen and nutrients critical to the…

One of the highlights of the visit to Trieste was the opportunity to finally meet an old blog-friend of mine. Franc Nekrep is a professor of Mikrobiology in Ljubljana, Slovenia and we have been reading each others blogs for a couple of years now. It was so much fun to finally meet in person. He…

Here are, quickly for now, some pictures from the yesterday's panel "Open Access; let's do it: top down, bottom up or both?" Stevan Harnad did his presentation first via Skype (from Montreal) which was, unfortunately, not recorded. The rest of the session was recorded and at some time in the…

Politicians are quite unfit for government. They are however very useful for ceremonial banquets, official openings, launchings, unveilings, and greeting foreign delegations, leaving more time for the genuine work of government to those of us who have the proper training and experience…

It's nice to get to know your fellow panelists REALLY well over a dinner and wine the night before the event. So we got together and had great fun: Sely Costa from Brasil, A.R.D. Prasad from India, Derek Law and his wife from Scotland, Stefania from Italy and myself. Warning - marine biology…

Trieste at night. Smell of the Adriatic sea, in which I learned to swim some decades ago, just two towns (and two border crossings) away from here. Ponte Rossa, where I got my first jeans, back in 1970 or so. Nostalgia.

How birds know when and where to migrate (from April 03, 2006) I've never ever expected to see the word "Zugunruhe" in New York Times! But here it is. It is one of my most favourite words of all times (right after "elusive"), and is even described pretty accurately: Zugunruhe brooks no confusion.…

Going into more and more detail, here is a February 11, 2005 post about the current knowledge about the circadian organization in my favourite animal - the Japanese quail. Japanese quail (Coturnix coturnix japonica), also known as the Asian Migratory Quail, are gallinaceous birds from the family…

Rest is not idleness, and to lie sometimes on the grass under trees on a summer's day, listening to the murmur of the water, or watching the clouds float across the sky, is by no means a waste of time. - Sir John Lubbock

I am having a blast in Trieste - FEST is fantastic, people friendly, program interesting, the smell of Adriatic evokes nostalgia (I learned to swim in the northern Adriatic), but I am really pissed with the Jolly Hotel I am in. Room is fine. But they charge wifi at exorbitant prices. About a year…
