Science: Wired
reports on a study of the number of generations it would take to evolve from the size of a mouse to that of an elephant. (A lot.)
Speaking of rates of evolution, the New
York Times reports on a virus
that changes very rapidly, and how dangerous this can be.
I learned something I didn't know, or had forgotten, namely
that some spores (which are microscopic) have elaters
attached to them. See here
and here
for some great photos.
