Two interesting articles in the Economist's Science & Technology section from last week's issue.
The (social) science of civil war. The article examines different programs which model the possibility of a civil war-related messiness. Predicting terrorist attacks in a guerrilla warfare setting, understanding the evolution of protests, looking at "what-if" scenarios during growing conflict.
Telephoning habits of the different sexes as they age. Once people hit the grandparent-ish age, the people they call changes quite a bit. Women start calling other women, presumably their daughters, to assist in relationship-building (of the child producing kind) and child-rearing. The reasoning: if you can't produce babies anymore yourself, better make sure your offspring are producing and raising babies successfully. Guys, no such (biological) necessity; men do call women at a lower rate as the get older, though (not as much need to call the wife).
