Microplastics found in human brain research
Publicado em 17 de setembro de 2024
Researchers in Brazil have found microplastics in human brain tissue, a new study published on Monday in the American Medical Association's journal JAMA reveals . Microplastics pollution has emerged in recent years as a growing environmental and health concern.
Tiny pieces of plastic measuring between 0.0055 and 0.025 millimeters (0.00021 to 0.00098 of an inch) in size were previously detected in various human tissues and in the bloodstream. Their presence in the brain, however, up until [...]

Despite peculiarities, conservation challenges similar in Madagascar, Brazil
Publicado em 04 dezembro 2022Sau Paulo [Brazil], December 4 (ANI): Madagascar's nature is so unique that 82 per cent of its plant species and 90 per cent of its animals are endemic, found exclusively on the island off the coast of Southeast Africa. A population so impoverished that the country's human development index (HDI) is one of the lowest in the world and lives among this rare biodiversity, creating the problem of balancing conservation with economic and social growth. Two studies published in the journal [...]ver notícia -
New research adds to understanding of genetic factors that naturally protect people from COVID-19
Publicado em 22 novembro 2022Washington [US], November 22 (ANI): Two recent papers by Brazilian researchers have added to the scientific understanding of the genetic factors that protect people from SARS-CoV-2 infection or prevent progression to severe COVID-19. The first describes the findings of a study involving a group of resilient older people aged 90 or more, while the second examines a case of severe COVID-19 in identical twins, only one of whom had long-term symptoms of the disease. Since 2020, researchers in [...]ver notícia -
Researchers discover pyramidal neurons that gauge speed, location
Publicado em 15 setembro 2022Washington [US], September 15 (ANI): A group of researchers has made an important contribution to scientists' understanding of the brain's navigation system by identifying a subtype of these neurons that can gauge speed with great precision, more than a decade after the role of pyramidal neurons in mental representations of space and location was discovered. "In experiments involving animals, we demonstrated an association between the electrical activity of inhibitory [...]ver notícia
