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.

Infusing anti-HIV antibodies provides macaques with protection against infection for up to six months, according to a study.

Monkeys genetically engineered with multiple copies of an autism-linked human gene display some autism-like behaviors, scientists show.
