Breathing could bring microplastics into the human brain, study shows
Publicado em 19 setembro 2024
MONDAY, Sept. 16, 2024 (HealthDay News) -- For the first time, scientists have detected microscopic microplastics lodged in the human brain.
Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell centers, the olfactory bulb.
The particles were likely breathed in over a lifetime, since tiny floating microplastics are ubiquitous in the air.
Although microplastics have already been found in human lungs, intestines, [...]

10,000 year old skeleton in Sao Paolo found to have Amerindian DNA like Indigenous people living there today FAPESP Phys.org Mon, 31 Jul 2023 12:00 UTC
Publicado em 31 julho 2023An article published on July 31 in Nature Ecology & Evolution reveals that Luzio, the oldest human skeleton found in São Paulo state (Brazil), was a descendant of the ancestral population that settled the Americas at least 16,000 years ago and gave rise to all present-day Indigenous peoples, such as the Tupi. Based on the largest set of Brazilian archaeological genomic data, the study reported in the article also offers an explanation for the disappearance of the oldest coastal [...]ver notícia -

Gravitational action of sun and moon influences behavior of animals and plants - study
Publicado em 05 janeiro 2022The rhythms of activity in all biological organisms, both plants and animals, are closely linked to the gravitational tides created by the orbital mechanics of the sun-Earth-moon system. This truth has been somewhat neglected by scientific research but is foregrounded in a study by Cristiano de Mello Gallep at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, and Daniel Robert at the University of Bristol in the United Kingdom. An article on the study is [...]ver notícia -
Astronomers have identified asteroids of interstellar origin inhabiting the solar system
Publicado em 20 julho 2020A study conducted by scientists at São Paulo State University's Institute of Geosciences and Exact Sciences (IGCE-UNESP) in Rio Claro, Brazil, has identified 19 asteroids of interstellar origin classified as Centaurs, outer Solar System objects that revolve around the Sun in the region between the orbits of Jupiter and Neptune. An article on the study titled "An interstellar origin for high-inclination Centaurs" is published in the Royal Astronomical Society's [...]ver notícia -
Extreme Rainfall Days In Metropolitan São Paulo Have Risen Four-Fold In Seven Decades
Publicado em 09 abril 2020Intense rainfall has become increasingly widespread in metropolitan São Paulo, Brazil. The capital of the condition of São Paulo is the major city in the southern hemisphere. The metropolitan area endured from flooding owing to large rain in February.

This was the next highest 24-hour amount of money for the thirty day period due to the fact 1943, according to Brazil’s [...]ver notícia -
A newly identified electric eel species has the strongest shock of any living creature, study says
Publicado em 11 setembro 2019Two new electric eel species have been identified in the Amazon basin, including one fish with a record-breaking shock, scientists say. Researchers had previously identified only one species of electric eel in more than 250 years of studying the creatures that lurk in South American waters and stun their prey with electric discharges. However, the new genetic and ecological analysis, published Tuesday in the peer-reviewed Nature Communications, identifies a total of three unique [...]ver notícia -
New avian virus discovered in migratory Brazilian bird
Publicado em 31 julho 2017Researchers at the University of São Paulo's Biomedical Science Institute (ICB-USP) in Brazil have discovered a new virus in a migratory bird species. This is such a rare find that it can be considered a stroke of luck, especially because the virus in question is avian paramyxovirus 15, which belongs to the same family as avian paramyxovirus 1, the pathogen that causes Newcastle disease. This disease is not a health hazard for humans but can be lethal to wildfowl and domestic poultry. "We [...]ver notícia
