Pequenos primatas com faces mais expressivas do que se pensava

Universidade de Quioto adaptou o sistema humano de codificação de acção facial, ou FACS, como uma ferramenta para comparações sistemáticas de músculos faciais entre espécies. As contrações musculares faciais movem porções da pele, produzindo um conjunto de mudanças de aparência que são visíveis no rosto. O FACS analisa e classifica os movimentos visíveis feitos pelos músculos faciais através das chamadas unidades de acção.

Apes show dramatically different early immune responses compared to monkeys

A new study out of the University of Chicago and the University of Illinois Urbana-Champaign in humans, chimpanzees, rhesus macaques and baboons has found key differences in early gene expression in response to pathogen exposure, highlighting the importance of choosing the right animal model for the right questions.

NIH Grant aims to enhance scientific models of aging focused on creating better intervention tools for age-related decline

The Southwest National Primate Research Center (SNPRC) at Texas Biomedical Research Institute and the University of Texas Health Science Center at San Antonio received a $1.3 million collaborative grant to continue the San Antonio Marmoset Aging Program (SA MAP) and further define the hallmarks of aging in a nonhuman primate (monkey) model. Developing the marmoset model will allow for eventual testing of interventions in additional model systems that could slow or change age-related decline in humans.
