A plant present in Brazil is capable of colonizing deforested areas
Publicado em 08 de agosto de 2016
Researchers have studied the genetic diversity and differentiation patterns of the native pioneer understory tree Miconia affinis. They collected leaf tissue from approximately 30 reproductive trees bearing inflorescences or infructescences in 11 different populations and estimated the influence of geographic distance, elevation and deforestation on the genetic structure. The genetic differentiation of this tree species significantly increased with elevation and geographic distance between populations.

Male hormone reverses cell aging in clinical trial
Publicado em 25 julho 2016Date: July 25, 2016 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Sex hormones can stimulate production of telomerase, an enzyme naturally found in the human organism, new research shows. The strategy was tested in patients with genetic diseases associated with mutations in the gene that codes for this enzyme, such as aplastic anemia and pulmonary fibrosis. The authors say that the results suggest that the approach can combat the damage caused to the organism by [...]ver notícia -
