As thousands of troops and government workers struggle to restore normal life to Puerto Rico, a small group of scientists is racing to save more than 1,000 monkeys whose brains may contain clues to some of the most important mysteries of the human mind. One of the first places Hurricane Maria hit in the US territory Sept. 20 was Cayo Santiago, known as Monkey Island, a 40-acre outcropping off the east coast that is one of the world's most important sites for primate research, reports the AP. The storm destroyed virtually everything on the island, stripping it of vegetation, wrecking the monkeys' metal drinking troughs, and crushing the piers that University of Puerto Rico workers use to bring in bags of monkey chow—brown pellets of processed food that complete the primates' natural vegetation diet. More:

  • The history: The island's history as a research center dates to 1938, when the man known as the father of American primate science brought a population of Indian rhesus macaques to the United States. Clarence Ray Carpenter wanted a place with the perfect mix of isolation and free range, where the monkeys could be studied living much as they do in nature without the difficulties of tracking them through the wild. Since then the 400 or so macaques have reproduced and expanded their numbers, becoming the world's most studied free-ranging primate population and something of a living library.
  • Current research: Researchers from Yale, the University of Pennsylvania, New York University, and others have been spending much of the year on the island studying everything from the monkeys' eye movements to the genes and behavior of socially aberrant individuals that may provide insight into the causes of autism.
  • The current effort: The university staff and local employees who keep Monkey Island running are frantically ferrying bags of chow in a tiny skiff, feeding the macaques a survival diet and trying to reassemble the rainwater collectors and drinking troughs that keep the animals alive in the tropical sun.
  • The risks: The monkeys all carry herpes B, a version of the virus that is harmless to macaques but can be fatal in humans. Anyone who comes into contact with monkey saliva or urine must undergo rigorous decontamination and treatment with antiretroviral drugs. Humans also pose risks for the monkeys. Because the hurricane destroyed the island's chemical toilet, researchers and workers can stay only until they need a bathroom break: Human waste could start an epidemic that could wipe out the monkeys.
