New research from the Max Planck Institute of Evolutionary Anthropology in Leipzig, Germany shows that unlike humans, chimpanzees conform to traditional economic models. The research, conducted by Keith Jensen, Josep Call and Michael Tomasello, used a modification of one of the most widely used and accepted economic tools, the ultimatum game.

A sudden loss of T cells -- white blood cells crucial to the immune system -- is not the trigger for the onset of AIDS, according to a study published in the September 2007 issue of the Journal of Immunology by a team of researchers at Tulane National Primate Research Center.

Female rhesus monkeys use special vocalizations while interacting with infants, the way human adults use motherese, or “baby talk,” to engage babies’ attention, new research at the University of Chicago shows.

Monkeys seem to learn the same way humans do, a new research study indicates.

When orangutans use gestures to get their point across, they rely on the same basic strategy that people follow in playing the game of charades. Captive orangutans intentionally modify or repeat hand or other signals selectively based on the success or failure of their first attempt, according to a August 2nd study in Current Biology, a publication of Cell Press.

Animals’ natural foraging decisions give an insight into their cognitive abilities, and primates do not automatically choose the easy option.

Primate tourism, an economic benefit and conservation tool in many habitat countries, has exploded in popularity over the past two decades in places like China, Borneo, Uganda, Rwanda, Northern Sumatra, Madagascar, Gabon and Central America.

A team of scientists from WWF and Conservation International (CI) has discovered the world’s largest known population of grey-shanked doucs (Pygathrix cinerea), increasing chances that the Endangered monkey can be saved from extinction.

New research from Columbia's Primate Cognition Laboratory has demonstrated for the first time that monkeys could acquire meta-cognitive skills: the ability to reflect about their thoughts and to assess their performance.

Fresh evidence that suggests monkeys can learn skills from each other, in the same manner as humans, has been uncovered by a University of Cambridge researcher.

Researchers at the Johns Hopkins School of Medicine and their colleagues have found that mice simply expressing a human light receptor in addition to their own can acquire new color vision, a sign that the brain can adapt far more rapidly to new sensory information than anticipated.
