Publication of a new map showing all the above-ground biomass in the Brazilian Amazon is good news in the context of the severe crisis afflicting the world's largest contiguous tropical rainforest. Using airborne laser scanning and satellite imagery calibrated by field forest inventories and integrated by heavy-duty computer processing and machine learning, the map reflects the world's largest survey of tropical forest biomass ever conducted. Results of the study are reported in an [...]

Researchers in Brazil conducted experiments on a zinc oxide-based photocatalyst, discovering its effectiveness in degrading sertraline, an emerging pollutant. An article published in the Chemical Engineering Journal outlines a strategy for developing a material based on zinc oxide (ZnO) capable of efficiently degrading sertraline. This antidepressant, detected globally in groundwater along with other drugs, poses a challenge for conventional wastewater treatment methods due to its [...]

A low-cost technology involving nanoparticles loaded with antibiotics and other antimicrobial compounds that can be used in multiple attacks on infections by the bacterium responsible for most cases of tuberculosis has been developed by researchers at São Paulo State University (UNESP) in Brazil and is reported in an article published in the journal Carbohydrate Polymers. Results of in vitro tests suggest it could be the basis for a treatment strategy to combat multidrug bacterial [...]

To fill gaps in knowledge of yellow fever (YF), a group of researchers in Brazil affiliated with the Department of Pathology at the University of São Paulo's Medical School (FM-USP), Hospital das Clínicas (HC, the hospital complex run by FM-USP), the Heart Institute (InCor, linked to HC) and Emílio Ribas Institute of Infectious Diseases (IIER) decided to study the pathogenesis of YF-associated heart injury. The team was led by Fernando Rabioglio Giugni, a [...]

An article published in the Chemical Engineering Journal describes a strategy to produce a material based on zinc oxide (ZnO) capable of degrading sertraline, an antidepressant that has been detected, like other drugs, in groundwater worldwide and is considered an emerging pollutant. This kind of substance has certain physicochemical properties that hinder removal by conventional wastewater treatment methods. The research was supported by FAPESP and conducted in Brazil by scientists at the [...]

Atopic dermatitis (AD) is a chronic inflammatory skin disease whose main symptoms are redness, swelling, and itchy rashes. It is more common in people with a genetic predisposition. Manifestation of symptoms depends on interactions among the immune system, environmental factors and gut microbiota. Many pieces of this complex jigsaw puzzle are still undiscovered, but recent research has identified relevant factors. For example, alterations in gut microbiota composition can contribute to the [...]
