Oxidative Stress in an African Ground Squirrel, a Case of Healthy Aging and Reproduction.

Oxidative stress plays a crucial role in mediating life-history processes, where it can compromise survival and reproduction through harmful alterations to DNA, lipids, and proteins. In this study, we investigated oxidative stress in Cape ground squirrels (), a longer-lived African ground squirrel species with a high reproductive skew and unique life history strategies. We measured oxidative stress as total antioxidant capacity (TAC), total oxidant status (TOS), and an oxidative stress index (OSI) in blood plasma from individuals of approximately known ages.

The impact of terrorist attacks on cultural values as expressed in books.

We assessed the effects of the 9/11/2001 terrorist attacks on the salience of moral words and phrases in the United States, Great Britain, and Spanish-speaking countries, focusing particularly on those phrases related to authority and loyalty. Our predictions were that the 9/11 attacks would increase the salience of authority phrases suggestive of disorder ("chaos", "disobedience", etc, labeled authority-vice) and decrease words and phrases suggestive of organization ("hierarchy", "obedient", etc: authority-virtue) in books published in the United States. Similarly, we anticipated that the salience of phrases consistent with fidelity to members of one's social group ("allegiance", "one for all", loyalty-virtue), would decrease, and those suggestive of social corrosion ("betrays", "back stabs", loyalty-vice) would increase.
