Every time a gene is replicated, or really, a chromosome (during cell division), a bit of the end of a gene may be lost, owing to the way this process happens. This is part of the process of aging. City Great Tit ( Parus major ) telomeres shortened. Telomeres are repetitive sequences of genetic material sitting at the ends of genes.

Along with this ontogenetic reconstruction, the researchers also identified two genetic pathways that are associated with this developmental process. So this new research is very interesting, and we applaud the scientists for their work. The students seem rarely impressed or interested, but I enjoy telling them anyway.) Here’s the thing.

For example, I was going to add “no tail” to the list of features above, what all frogs share, when I remembered that there are indeed a small family of Tailed frogs, four species in New Zealand and two in North America (though, the tails are quite tiny). If you don’t live near a science museum, then read this chapter.

This is more than eBird reports–a checklist generated from the citizen science database lists only 1,413 species. But, the numbers are quite large, and the birds organized in groupings that, for the most part, make it an easy process to figure out which Antwren (or Woodcreeper or Seedeater) is which.

I come from a family where the worse the situation, the faster and more furiously the wisecracks fly, so I suppose I’m hardwired to look for humor. What was that process like? The book is darkly funny. Why did you decide it was important to find humor in Luna’s experience? I can’t write stories that are unrelentingly grim. Energetic.

This is also where Johnson starts talking about the cost of the theft to the Museum and to science. He says he is motivated by what he has learned from the curators about the skins importance to science, but he is also clearly irritated by the fact that Rist has gotten off so lightly.

Describing gull plumage is a combination of science, graphic art, and visual metaphor. I suppose this works with such a small family, but it made my librarian brain ache just a little bit.
