whose junkpile just happens to function like an alien’s supercomputer
From Carl Zimmer at the New York Times:
In the journal Neuron, a team of scientists has unveiled an unprecedented view of X-chromosome inactivation in the body. They found a remarkable complexity to the pattern in which the chromosomes were switched on and off.
At the same time, each copy of the X chromosome contains versions of genes not found on its partner. So having two X chromosomes gives females more genetic diversity than males, with their single X chromosome. Because of that, females have a genetic complexity that scientists are only starting to understand.
“Females simply have access to realms of biology that males do not have,” said Huntington F. Willard, the director of Duke University’s Institute for Genome Sciences & Policy, who was not involved in the research.
We should be working but …
