Astronomers unveil 'heart' of Eta Carinae

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

An international team of astronomers has imaged the Eta Carinae star system -- a colossal binary system that consists of two massive stars orbiting each other -- including a region between the two stars in which extremely high-velocity stellar winds are colliding. With these observations, is possible to map the zone in which the two stellar winds collide and make sure we genuinely understand the basic parameters of the binary system.

Peer-Reviewed Publication

A 40 percent reduction in dietary caloric intake increases mitochondrial calcium retention in situations where intracellular calcium levels are pathologically high. In the brain, this can help avoid the death of neurons that is associated with Alzheimer's disease, Parkinson's disease, epilepsy and stroke, among other neurodegenerative conditions.

New library of human stem cells with the Brazilian genetic admixture

University of Sao Paulo Scientific Outreach Unit
Peer-Reviewed Publication

New human pluripotent stem cells lines increase the diversity of the available ones because are derived from individuals of the Brazilian population -- an admixture of European, African and Native American genomic ancestry. They can serve as an in vitro system for the identification of novel leads, for testing drug toxicity and for addressing the issue of differential drug response, a phenomenon greatly influenced by genetic factors.
