The impacts of climate change and the urgency to act have not gone unnoticed in Latin America and the Caribbean (LAC). The Institute of the Americas (IOA) has released a policy white paper entitled, Nationally Determined Contributions Across the America: A Comparative Hemispheric Analysis in an effort to better assess progress made to date by countries across the Americas in delivering on their climate commitments. The white paper provides a timely snapshot of progress made, while also highlighting the serious funding gaps that remain if LAC countries are going to deliver on their previously agreed upon climate pledges.

Humans are unusual in that we depend on shared foods, especially among families and friends and between potential mates. Food sharing occurs between healthy individuals and those that are infirm or elderly. We also differ from other great apes in our early ages at weaning, late ages at maturity, short birth intervals and survivorship decades past menopause. The emergence of these patterns was crucial to early human development. In light of observations among modern East African hunter-gatherers, University of Utah professor James O’Connell evaluates two alternatives. He discusses one hypothesis that focuses on males acquiring big game meat and marrow to provide for mates and offspring. The other hypothesis surrounds how certain kinds of savanna plant food set up the forager interdependence which propelled all aspects of life history change.

To study aging, scientists are looking to outer space. Space travel causes changes to the body that are similar to aging. Dr. Sonja Schrepfer, UCSF Division of Adult Cardiothoracic Surgery, investigates space-related physiological changes, similar to those observed during aging, including defects in bone healing, loss of cardiovascular and neurological capacity, and altered immune function.
