<p> OH, TO BE IN ENGLAND...
</p>
<p> A bird called the blackcap has been showing up in Britain
lately, in droves. Seems these birds of the forest, which used
to winter in the western Mediterranean, have changed their
migratory routes. German researchers studied some blackcaps and
their offspring, and report in Nature that the change is
genetic; responding to some environmental signal, the birds'
hard-wired migratory instructions have evolved in an
astonishingly short 30 years.

<p> Fruit flies are the mules, if you will, of genetic research;
they breed fast, and their simple chromosomes are ideal for the
study of heredity. Now a group of U.S. biologists has found a
way to freeze living fly embryos. Not only does that guarantee a
stable fly supply, but it is a landmark achievement in another
sense: fruit flies are the most complex organisms ever to be lab
frozen and revived. The technique could lead, albeit far down
the road, to the freezing of mammals--even humans, maybe.
