Astronomers find evidence of a planet with a mass almost 13 times that of Jupiter
Publicado em 08 abril 2019
In the past three decades, almost 4,000 planet-like objects have been discovered orbiting isolated stars outside the Solar System (exoplanets). Beginning in 2011, it was possible to use NASA’s Kepler Space Telescope to observe the first exoplanets in orbit around young binary systems of two live stars with hydrogen still burning in their core.
Brazilian astronomers have now found the first evidence of the existence of an exoplanet orbiting an older or more evolved binary in which one of the [...]

Amoebae diversified at least 750 million years ago, far earlier than expected
Publicado em 01 março 2019Brazilian researchers have reconstructed the evolutionary history of amoebae and demonstrated that at the end of the Precambrian period, at least 750 million years ago, life on Earth was much more diverse than suggested by classic theory. The study, which was supported by São Paulo Research Foundation — FAPESP, revealed eight new ancestral lineages of Thecamoebae, the largest group in Amoebozoa. Thecamoebians are known as testates because of their hard outer carapace or [...]ver notícia -
Sofosbuvir rids organism of chikungunya and yellow fever viruses
Publicado em 18 dezembro 2018A study performed at the University of São Paulo’s Biomedical Science Institute (ICB-USP) in Brazil shows that sofosbuvir, a drug used to treat chronic hepatitis C, is capable of eliminating chikungunya virus and yellow fever virus. “Human cells infected by chikungunya virus were treated with sofosbuvir, and the drug eliminated the virus without damaging any cells. The drug proved to be 11 times more effective against the virus than against cells,” said Rafaela Milan Bonotto, a coauthor [...]ver notícia
