For the first time in South America, researchers recorded the use of ultrasound by a frog endemic to the Atlantic Rainforest in Brazil, which has more species of amphibians than any other country. Other frogs may use very high-frequency calls for the same purpose.

Researchers working in Gamboa, Panama, found that the vibrant red hind-leg flags of matador bugs serve as an intricate defense strategy rather than a mating display or distraction tactic. Through experiments involving predatory birds and prey adorned with bug flags, the study revealed that these flags act as warning signals, deterring predator attacks.

Experiments conducted at Butantan Institute in São Paulo used phage display to screen 12,000 proteins found in Schistosoma mansoni, the worm that causes the disease. The method deployed bacteriophages, viruses that infect bacteria, to identify key parasit

In a new paper, researchers from the Alliance of Bioversity International and CIAT have outlined how deeper roots, artificial intelligence (AI) and remote sensing can help measure and increase soil carbon sequestration.

Given the limited capabilities within the public sector, tourism planning consultants play a crucial role in public policy efforts in Ecuador. Based on social practice theory, this study examined the planning practices of 46 consultants hired by public institutions in the country between 2017 and 2021. 

Analysis of skeletons exhumed at a burial ground dating from the period 500-400 BCE, shortly after the collapse of the Chavín culture, revealed lethal injuries inflicted on men, women and children, as well as signs of material poverty. The period of violence investigated in the study may have seen the fall of the Chavín culture and a shift from theocracy to secular government.

SyncLight 2024 will discuss the recent opportunities offered by advanced experimental synchrotron techniques available at Sirius, the Brazilian 4th generation light source.

Brazilian scientists tested a simple and sustainable method for monitoring and degrading a mixture of polycyclic aromatic hydrocarbons, compounds present in fossil fuels and industrial waste. The mixture of pollutants was degraded by means of a photochemical system in which a light source is activated by microwave radiation
