Why, Oh Y?

A toothpick and a bit of chance shaped David Page’s career, which he has dedicated to understanding the mammalian Y chromosome and fetal germ cell development.

The Sex Parts of Plants, 1736

Carl Linnaeus’s plant classification system was doomed, and he knew it.

In the evolutionary arms race between pathogens and hosts, genetic elements known as transposons are regularly recruited as assault weapons for cellular defense.

Social adversity shapes humans’ immune systems—and probably their susceptibility to disease—by altering the expression of large groups of genes.

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.

Marie-Paule Kieny started off her comment oh so right, but then continued oh so wrong.  In this case, forget the bioethicists. Kieny should have said, "We need to tell the bioethicists that there is no other choice."
