Microplastics found in human brain research
Publicado em 17 setembro 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 [...]

Research shows bacterial protein capable of keeping human cells healthy
Publicado em 10 novembro 2023Washington DC [US], November 10 (ANI): Researchers at the University of Sao Paulo (USP) in Brazil, in collaboration with colleagues in Australia, discovered a unique bacterial protein that can maintain human cells healthy even when the cells are heavily contaminated with bacteria. The discovery could lead to new treatments for a wide range of mitochondrial dysfunction-related ailments, including cancer and auto-immune disorders. Mitochondria are organelles that provide the majority of the [...]ver notícia -

Research team creates biodegradable film that keeps food fresh for longer
Publicado em 19 julho 2023Washington DC [US], July 18 (ANI): Because petroleum-derived packaging materials degrade slowly and are rarely recycled, there has been a massive buildup of plastic in landfills and the ocean. To address this issue and meet the growing demand for products that are safe for human health and the environment, the food industry is investing in the development of more sustainable packaging alternatives that preserve nutritional quality as well as organoleptic traits such as colour, taste, smell, [...]ver notícia -

Transcranial stimulation effective for aerobic exercise
Publicado em 25 agosto 2021Brasilia [Brazil], August 25 (ANI): Transcranial direct current stimulation (tDCS) can increase the benefits of aerobic exercise and improve the gait of patients with Parkinson's disease immediately after a session. Step time variability decreases, reaction time shortens, and executive control of gait is enhanced. These were the main findings of a randomized, double-blinded, sham-controlled crossover study of 20 volunteers by researchers at Sao Paulo State University's Institute [...]ver notícia -

Jolting discovery: Powerful new electric eel found
Publicado em 11 setembro 2019WASHINGTON (AP) — Researchers report two newly discovered species of electric eels in South America, one of which can deliver a bigger jolt than any other known animal. The researchers collected 107 eels in four countries and found differences in their DNA, along with minor physical variations. One species had the ability to generate 860 volts of electricity, more than the 650 volts discharged by the only previously identified type of electric eel. While 250 species of fish in South [...]ver notícia
