The seven primates came into contact with a dye that was used on their mothers, documents reveal.

For primates, males’ fancier ornaments are linked with smaller testes, according to a new comparative study.

Researchers edited macaque embryos to induce symptoms of sleep disorders and chose one animal to clone. A bioethicist questions the study’s appropriateness.

A perception of sustained focus may actually be the result of cycles of fluctuating rather than continuous neural activity, according to new behavioral and neurological data from studies in humans and macaques.

Inflammation may be a strong contender for the connection between mom’s weight and children’s neurodevelopment, according to lab studies on animals.

Researchers studying macaques in Morocco find that socialization improves the monkeys’ odds of surviving the winter. 

The findings highlight the need for long-term monitoring of children exposed to the virus, say scientists. 

The approach, which has never before been successfully attempted in primates, could lead to improved animal models for human biology and disease.

Optogenetic stimulation of the perirhinal cortex can cause macaques to process never-before seen-objects as familiar and known objects as brand new.

In tissue samples from rhesus macaques, researchers find the virus in the same immune-privileged sites where Ebola has been found to persist in humans.

Anatomical analysis suggests monkeys possess all the hardware for human-like speech, they just lack the neurological capacity to use it.

Scientists image fetal brain lesions in a pigtail macaque whose mother was infected with the virus while pregnant.

The brains of primates and mice follow the same exponential rule of connectivity, according to a study.
