Circadiana: Clock in the primate adrenal
http://circadiana.blogspot.com/2006/05/clock-in-primate-adrenal.html
The early bird catches the worm. Tuesday, May 23, 2006. Clock in the primate adrenal. I got a new paper about circadian rhythms in primates: Twenty-four hour rhythmic gene expression in the rhesus macaque adrenal gland. PDF), by Dario Lemos, Jodi Downs and Henryk Urbanski. The way the study is presented in the press release (now offline! It sounds like this is a big surprising breakthrough, but I am not too impressed. The work is good and useful, but the findings are far from Earth-shattering. I'd get re...

Circadiana: Clocks in Bacteria I: Synechococcus elongatus
http://circadiana.blogspot.com/2006/03/clocks-in-bacteria-i-synechococcus.html
The early bird catches the worm. Wednesday, March 08, 2006. Clocks in Bacteria I: Synechococcus elongatus. As I stated in the introductory post. All three hypotheses for the origin. Next time, I will focus on the contributions of cyanobacteria to the understanding of the origin, evolution and adaptive function of circadian clocks. References and further reading:. 1] Circadian clock mutants of cyanobacteria. 2] Circadian clocks in prokaryotes. 3] Circadian Rhythms in Rapidly Dividing Cyanobacteria. By Tet...

Circadiana: WWDD4: Power of Darwinian Method
http://circadiana.blogspot.com/2005/01/wwdd4-power-of-darwinian-method.html
The early bird catches the worm. Thursday, January 06, 2005. WWDD4: Power of Darwinian Method. IV Power of Darwinian Method. One man's "magic" is another man's engineering. "Supernatural" is a null word. Success of the comparative method? What would have happened if the clocks research did not do comparative work? On the Aims and Methods of Biology. What is the object of study of the science of biology? How do they work? How do they behave? How do they interact with the environment? The Honorable Venusia...

Circadiana: Clock Tutorial #6: To Entrain Or Not To Entrain, That Is The Question
http://circadiana.blogspot.com/2005/02/clock-tutorial-6-to-entrain-or-not-to.html
The early bird catches the worm. Thursday, February 03, 2005. Clock Tutorial #6: To Entrain Or Not To Entrain, That Is The Question. Let's now continue our series of Clock Tutorials with an introduction to some phenomena (and related terms and concepts) observed in the laboratory in the course of doing standard circadian experiments. Such experiments usually involve either the study of properties of freerunning rhythms. Check the old tutorials, especially CT2. Of rhythms to environmental periodicities.

Circadiana: Clocks in Bacteria III: Evolution of Clocks in Cyanobacteria
http://circadiana.blogspot.com/2006/04/clocks-in-bacteria-iii-evolution-of.html
The early bird catches the worm. Wednesday, April 19, 2006. Clocks in Bacteria III: Evolution of Clocks in Cyanobacteria. As you probably know, my specialty are birds, so writing this series on clocks in microorganisms was quite an eye-opener for me and I have learned a lot. The previous two posts cover the clocks in the cyanobacterium Synechococcus elongatus. The first bacterium in which circadian rhythms were discovered and, thus, the species most studied to date. The work in Synechococcus. Moreover, t...

Circadiana: Clocks in Bacteria IV: Clocks in other bacteria
http://circadiana.blogspot.com/2006/04/clocks-in-bacteria-iv-clocks-in-other.html
The early bird catches the worm. Sunday, April 30, 2006. Clocks in Bacteria IV: Clocks in other bacteria. For decades, it was thought that prokaryotes did not have. Circadian clocks. Then, a clock was discovered in a unicellular cyanobacterium. Later also in Synechocystis. 2]) which quickly became an important model. So, two recent papers tried to address this question - do photosynthetic bacteria exhibit circadian rhythms? Van Praag et al.[3], used Rhodospirillum rubrum. In the former, the measured outp...

Circadiana: Circadian Clocks in Microorganisms
http://circadiana.blogspot.com/2006/02/circadian-clocks-in-microorganisms.html
The early bird catches the worm. Thursday, February 23, 2006. Circadian Clocks in Microorganisms. Many papers in chronobiology state that circadian clocks are ubiqutous. That has been a mantra since at least 1960. This suggests that most or all organisms on Earth possess biological clocks. Rhythms of locomotor activity are the easiest to measure. It is no suprise that nobody looked at microorganisms back then - it was just technically too hard. The fact is that most of the pioneers in the field came ...

The early bird catches the worm. Wednesday, May 17, 2006. You may have noticed a new button on my sidebar that looks like this:. If you click on it, you will be transported to the homepage of one of my favourite science educational programs - the Project Exploration. This project is the brainchild of paleontologist Paul Sereno and his wife, historian and educator Gabrielle Lyons. If you do not know who Paul Sereno. Is the best preserved skeleton of a long-necked dinosaur. Sarcosuchus imperator. I got, ov...
