In which we consider the rather exuberant diversity of organisms and introduce the principle that evolutionary mechanisms are responsible for it.In medieval Europe there was a tradition of books known as bestiaries; these were illustrated catalogs of real and imagined organisms in which it was common for particular organisms to be associated with moral lessons.

What is the best way to eliminate clumping suspension cells used for transfection. Anti clumping agents interfere transfection and hence can't be used. Though maintaining the cell density low helps…

The IAVI G001 HIV vaccine trial looks promising. If it works, will it work by preventing a single cell from being infected, or by allowing the body to attack infected cells? What I'm trying to unde…

I'm quite curious on how animals view incestual pairings. Given there are enough mates around, i have quite observed that most females (subjects are dogs, cats, pigeons and chickens) would go choose

In this chapter, I describe how to estimate parameters from birth-death models using data on species diversity and ages, and how to use patterns of tree balance to test hypotheses about changing birth and death rates. I also describe how to calculate the likelihood for birth-death models on trees, which leads directly to both ML and Bayesian methods for estimating birth and death rates.

I am working with Next Generation Sequencing. I BLASTed the bovine de novo assembled contigs to the NCBI nucleotide database. I got a matching with a lot of species i.e. different kind of bacteria,
