Fight against obesity goes far beyond individual struggle to change lifestyle, scientists say

In an article published in Nature Metabolism, researchers based in Brazil and Mexico analyze the Latin American obesity epidemic from a broad perspective that includes socioeconomic, cultural and epigenetic factors. For the authors, solutions must focus on collective action rather than individualization of the problem.

A study conducted in a medium-sized city in São Paulo state (Brazil) found that chikungunya, which has caused major epidemics in several countries, can also circulate silently in a community, with few infections for years. The researchers produced a new profile of this arbovirus, underscoring the importance of disease surveillance to predict and prepare efficiently for epidemics.


An analysis of scientific papers published in a 15-year period on molecular methods to identify elasmobranch species shows that better detection of illegal trade has not enhanced protection.

The extreme weather events in the South of Brazil call for urgent coordinated action by governments and entities. The Paraíba do Sul basin is the focus for a “pilot” project conducted by a group of researchers.

The use of photobiomodulation and an antioxidant drug called idebenone strengthened the regenerative capacity of muscle fibers in an experimental model, a study conducted at the State University of Campinas shows.
