Cutting-edge technology has revealed the Amazonian rainforest hides thousands of records of ancient indigenous communities under its canopy, according to a study published in the journal Science. James Cook University’s Distinguished Professor Bill Laurance, a long-time Amazon expert, took part in the study. He said the Amazon is the world’s most diverse forest and according to the new study may also host more than 10,000 records of pre-Columbian earthworks – constructed [...]

The world’s most diverse forest, the Amazon, may also host more than 10,000 records of pre-Columbian earthworks (constructed prior to the arrival of Europeans), according to a new study. The new study combines cutting-edge remote sensing technology with archaeological data and advanced statistical modeling to estimate how many earthworks may still be hidden beneath the canopy of the Amazon rainforest and in which locations these structures are most likely to be found. The world’s [...]

More than 10,000 undiscovered pre-Columbian archaeological earthworks — and likely as many as 23,000 — rest undiscovered throughout the Amazon basin, hidden beneath the dense jungle foliage that blankets the region, according to a new study published in the 6 October issue of Science. The findings, which were derived from airborne laser mapping of a roughly 2,000-square-mile area of the Amazon, analysis of previously documented archaeological sites, and predictive [...]

Scientists are looking for new ways to treat toxoplasmosis, an infectious disease that affects more than a third of the world population. One of the most recent advances is reported in an article published in the journal PLOS ONE by researchers at the Jundiaí Medical School (FMJ) in São Paulo state, Brazil. The group screened 160 existing drugs to explore their potential repurposing to combat toxoplasmosis. The drugs belonged to the COVID Box, a library of compounds developed [...]

Rapid identification of patients contaminated by "superbacteria" known as "carbapenem-resistant Enterobacteriaceae" (CRE), with early isolation of these patients, reduces transmission in hospital emergency departments. However, keeping them in the emergency room (ER) for more than two days undermines containment because it increases the risk of infection via colonization. These are the key findings of a study by a group at the University of São Paulo's Medical [...]

With the rise in popularity of vegan diets, stemming from concerns over sustainability and animal rights, researchers from the University of São Paulo (USP) embarked on an exploration to comprehend the prevalence of dysfunctional dietary behaviors amongst vegans. The research, published in JAMA Network Open, sought to unravel whether veganism and its inherent food restrictions could be masking disordered eating attitudes and behaviors. The results of the study, which involved [...]

People who follow vegan diets have low risk of eating disorders, finds a study. The team at University of Sao Paulo (USP) in Brazil used an online questionnaire to collect socio-demographic data (such as education, income and location, among others) and information on eating habits for 971 participants aged 18 or older from all parts of Brazil. Analysing the data, they were able to arrive at the percentage of vegan diet followers reporting dysfunctional dietary behaviour and therefore, [...]
