Chimpanzees make judgments about the actions and dispositions of strangers by observing others’ behavior and interactions in different situations. Specifically, chimpanzees show an ability to recognize certain behavioral traits and make assumptions about the presence or absence of these traits in strangers in similar situations thereafter.

Trials are underway for a new vaccine to combat the most deadly form of malaria. For the first time ever, researchers will use a virus found in chimpanzees to boost the efficacy of the vaccine. The trials will take place at the University of Oxford's Jenner Institute, led by its Director, Professor Adrian Hill, and are funded by the Wellcome Trust.

Common human viruses are responsible for outbreaks of respiratory disease that have led to the decline of endangered chimpanzees in the wild, according to a study reported online on January 24th in Current Biology, a publication of Cell Press.

The deliberate ingestion of soil, or ‘geophagy’, has important health benefits for chimpanzees, according to Sabrina Krief and her colleagues from the Muséum National d’Histoire Naturelle in Paris, France. Far from being a dysfunctional behavior, geophagy has evolved as a practice for maintaining health amongst chimpanzees.

Socially-learned cultural behaviour thought to be unique to humans is also found among chimpanzees colonies, scientists at the University of Liverpool have found.

When it comes to choosing a place to live, male chimpanzees in the wild don’t stray far from home, according to a new report in the Dec. 27th Current Biology, a publication of Cell Press. The researchers found that adult male chimps out on their own tend to follow in their mother’s footsteps, spending their days in the same familiar haunts where they grew up.

A pioneering study of wild chimpanzees has found that these close human relatives do not routinely experience menopause, rebutting previous studies of captive individuals which had postulated that female chimpanzees reach reproductive senescence at 35 to 40 years of age.

Researchers have found no evidence that chimpanzees in the wild undergo menopause in the way that women do, according to a new report published online on December 13th in Current Biology, a Cell Press publication. That’s despite the fact that reproduction tends to peter out at a similar age in both species.

Young chimpanzees have an “extraordinary” ability to remember numerals that is superior to that of human adults, researchers report in the December 4th issue of Current Biology, a publication of Cell Press.

Chimpanzees crave roots and tubers even when food is plentiful above ground, according to a new study that raises questions about the relative importance of meat for brain evolution.
