Stem cell therapies offer the potential to treat diseases or conditions for which few treatments exist.

Stem cells, sometimes called the body’s “master cells,” are the precursor cells that develop into blood, brain, bones and all of your organs. Their promise in medical treatments is that they have the potential to repair, restore, replace and regenerate cells that could then be used to treat many medical conditions and diseases.

Archaeological starch grains consistent with those produced and stored in modern cojoba (Anadenanthera peregrina) seeds were identified, for the first time in the West Indies, in a coral milling base recovered in a small precolonial habitation site of Eastern Puerto Rico, in a context dated to A.D. 115–1250. Ethnohistoric, ethnographic, and previous archaeological data on cojoba from the West Indies and South America were surveyed in order to form plausible sociocultural interpretations of the findings.

Three articles in this issue address the role of vitamin and mineral supplements for preventing the occurrence or progression of chronic diseases.

The scaly-naped pigeon (Patagioenas squamosa) is threatened by hunting in the Caribbean. At present, the pigeon is abundant in Puerto Rico, but overharvesting is a major concern; therefore, the development of a sustainable harvest strategy is a management priority. The management objective of the harvest strategy is to maximize hunting opportunity while keeping the population above an abundance threshold (NT) of 260,000 pigeons.
