Developed by a team of Brazilian researchers, the device is made of plant-based material with little environmental impact, and detects pesticides in a few minutes, helping to certify food safety. Electrochemical sensors can combine affordability, rapid detection, miniaturization, convenience, easy of use, high selectivity and in situ pesticide detection.
The school will shed light on the latest advancements in multi-omics analyses and integration underlying the ultimate goal of improving food production and sustainability; submissions will be accepted until March 30, 2024.
Data from the Phase 3 clinical trial was published today (Thursday) in The New England Journal of Medicine. The vaccine is safe for both participants who have had dengue and those who have never been exposed to the virus before.
This part of the seafloor in the South Atlantic is rich in cobalt, nickel and lithium, as well as tellurium and other rare earths critical to the energy transition. The scientists plan to continue research on its natural processes as a contribution to prospecting efforts.Samples were collected during expeditions conducted in 2018 by researchers affiliated with the University of São Paulo (Brazil) and the University of Southampton (UK).
The study, which was conducted by Brazilian researchers, supports sustainable agriculture and offers contributions to public policy formulation. Crop-livestock integration (CLI) systems combine the growing of crops in rotation or consortium, especially grain crops such as soybeans, corn and sorghum, and forage plants used to feed cattle and pigs, with the raising of livestock, typically beef cattle.
In 18 cities of the Barretos region, where the proportion of Black people in the population is smaller, cancer kills more members of this ethnic group, whereas in the capital of the same state, it kills more White people, according to a study that compares cancer mortality rates and points to ways of reducing inequalities in diagnosis and treatment.
In experiments with rats, researchers at the University of São Paulo analyzed brain tissue and detected alterations in genes associated with energy metabolism.The prefrontal cortex is a brain region that is extremely susceptible to stress during adolescence. When it matures, it is crucial to enhanced cognitive control of emotions.
In experiments with rats, researchers at São Paulo State University detected changes in the expression of more than 700 genes in offspring. One of these genes is known to be associated with prostate cancer.
The material is a compound similar to clay and enables inspectors to carry out in-situ assessment of structural conditions in buildings, bridges, dams and other structures without having to drill for samples and analyze them in a laboratory.
The School will be held in São Paulo, Brazil, between October 27 and November 8. Sixty young environmental scientists and technicians from Brazil and abroad will be selected to participate.
