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.
Some species of cetacean are up to 4 meters in length, while others reach 30 meters. According to researchers at the State University of Campinas, genes that favor the colossal growth of these mammals also inhibit the development of cancer.
The researchers developed a model that projects the time taken for trees native to the Atlantic Rainforest to reach the ideal size to be harvested for the timber industry. The study analyzed data for 13 Atlantic Rainforest restoration areas involving ten species of native trees that could be commercially useful to the timber industry. Publication of the findings comes during the UN Decade on Ecosystem Restoration.
The land crab Johngarthia lagostoma occurs only on four ocean islands, three of which are in Brazil, but little is known of its natural history. Brazilian researchers discovered that a hill and beach on Trindade Island play a key role in the species’ reproductive cycle and survival.
