rhesus macaque

A group of self-styled screamologists are sifting through the noisiness of nonverbal human vocalizations and finding previously undemonstrated forms of communication.

Researchers find that the animals can account for others’ behavior and circumstances in their strategies.

Rhesus macaques can be infected with SARS-CoV-2, leading primate center scientists to try to prevent outbreaks in their colonies, especially as experiments on coronavirus start.

A polymer tube regenerates damaged nerves in monkeys, restoring near full functionality.

The auditory cortices of humans and rhesus monkeys respond very differently to harmonic tones.

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

Rhesus monkeys engineered to express a human gene reportedly show delayed brain development and better short-term memory. Fellow scientists are raising ethical red flags.

Humans might also inherit such brain changes, a new study suggests.

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.

Life at the bottom of the pecking order ramps up inflammation, according to new research, an effect that appears to be reversible.

A round-up of recent discoveries in behavior research

A cytomegalovirus-based vaccine eliminated simian immunodeficiency virus from rhesus macaques, raising hopes of a similarly effective HIV vaccine.

Researchers can see the differences in the neuronal activity of monkeys that use different strategies to reach out to a target.

In rhesus macaques, an individual's drop in the social hierarchy leads to overactive immune genes and, possibly, poor health.

Gene expression controlled from afar may have spurred the spurt in brain evolution that led to modern humans.
