clock | February 3, 2010Yes, years after I left the lab, I published a scientific paper. How did that happen?
Back in 2000, I published a paper on the way circadian clock controls the time of day when the eggs are laid in Japanese quail. Several years later, I wrote a blog post about that paper, trying to explain in lay terms what I did, why I did it, what I found, and how it fits into the broader context of this line of research. The paper was a physiology paper, and my blog post also focused on the physiological aspects of it.
But then, I wrote (back in March 2006 - eons ago in Web-time) an additional blog post…

"How does one distinguish a truly civilized nation from an aggregation of
barbarians? That is easy. A civilized country produces much good bird
literature."

This video is beautiful, so beautiful that you don't have to identify any of the birds captured on this video: you can just sit back and appreciate them. That said, I view IDing these birds as something fun to do, and a lot of my readers will agree.

Dinosaur books have become more colourful affairs of late, with the dull greens, browns and greys of yesteryear replaced by vivid hues, stripes and patterns. This has largely been a question of artistic licence. While fossils may constrain an artist's hand in terms of size and shape, they haven't provided any information about colour. But that is starting to change.
The fossils of some small meat-eating dinosaurs were covered in filaments that are widely thought to be the precursors of feathers. And among these filaments, a team of Chinese and British scientists have found the distinctive…
