Physically active men who are not overweight but who have a relatively high waist-stature ratio are more likely to develop heart disorders, according to a study by Brazilian researchers.

Brazilian researchers are the first to demonstrate the action of the synthetic compound PRIMA-1 (p53 reactivation with induction of massive apoptosis-1) against amyloid aggregates of mutant p53 protein, structure found in more than half of malignant tumors.

One of the most important aims of contemporary scientific research is finding out what makes the production of entropy predominate. This aim explains the current interest in studying mesoscopic systems, which are not as small as individual atoms but nevertheless display well-defined quantum behavior.

Study shows that deforestation, loss of biodiversity and economic damage done to communities living near dams have not been factored into the cost of these projects. Large dams also ignore the effects of climate change.

People who live within a particular ecosystem can have great influence on its ecology, particularly if they are motivated by economic forces. Payments for Ecosystem Services (PES) programs may lead to improved environmental health by offering landowners economic incentives to use their land in ecologically sound ways. A recent study by Smithsonian Tropical Research Institute (STRI) scientists and collaborators evaluated the economic feasibility of PES programs within the Panama Canal Watershed (PCW).

A study conducted in Brazil showed protective effects of flavonoid rutin against bleeding and inflammation due to snakebite.
