Meetings I’d like to go to….Part I

XI Congress of the European Biological Rhythms Society, organized in association with the Japanese Society for Chronobiology Hmmmm, Strasbourg in August. Fun for the family to do stuff while I chat with fellow chronobiologists, and just a short flight away from Belgrade…. Have to investigate if there’s a way for me to go…. And the…

Long-time readers of this blog remember that, some years ago, I did a nifty little study on the Influence of Light Cycle on Dominance Status and Aggression in Crayfish. The department has moved to a new building, the crayfish lab is gone, I am out of science, so chances of following up on that study…

Greg Cahill (1958-2008)

It is with great sadness that I learned that Dr.Greg Cahill died a few days ago, at the Houston airport, waiting for his flight. I have met Greg at several meetings of the Society for Research on Biological Rhythms and while, those being fairly large meetings, we never had big one-on-one conversations, I remember him…

Clocks and Immunity

This EurekAlert title got my attention this morning: Immunity stronger at night than during day: The immune system’s battle against invading bacteria reaches its peak activity at night and is lowest during the day. Experiments with the laboratory model organism, Drosophila melanogaster, reveal that the specific immune response known as phagocytosis oscillates with the body’s…

Totally cool: Phase Coupling of a Circadian Neuropeptide With Rest/Activity Rhythms Detected Using a Membrane-Tethered Spider Toxin: The regulation of the daily fluctuations that characterize an organism’s physiology and behavior requires coordination of the cellular oscillations of individual “clock” neurons within the circadian control network. Clock neurons that secrete a neuropeptide called pigment dispersing factor…

If you live in (most places in) the United States as well as many other countries, you have reset your clocks back by one hour last night (or last week). How will that affect you and other people? One possibility is that you are less likely to suffer a heart attack tomorrow morning than on…

The October issue of the Journal of Biological Rhythms came in late last week – the only scientific journal I get in hard-copy these days. Along with several other interesting articles, one that immediately drew my attention was Clock Gene Wikis Available: Join the ‘Long Tail’ by John B. Hogenesch and Andrew I. Su (J…

Circadian Biology in PLoS ONE

PLoS ONE has already published a large number of papers in chronobiology. But we want more. Hey, I work there – I want to see more. So, when I went to the SRBR meeting in May, I did whatever I could to explain how PLoS ONE works and why my colleagues in the field should…

As I announced this morning, there will be several guest posts here over the next several weeks. The first one, by Barn Owl of the lovely Guadalupe Storm-Petrel blog, is likely to appeal to a lot of my readers as it combines several of my own interests: ==================== In this guest-post for A Blog Around…

Glow worms glimmer on cue: University of Queensland researcher and lecturer Dr David Merritt has discovered that Tasmanian cave glow-worms are energy conservationists: they switch their lights off at night-time. The discovery was made during a partially funded UQ Firstlink study, which revealed that the glow-worm’s prey-luring light output is governed by circadian rhythms, regardless…
