Amoebae Diversified At Least 750 Million Years Ago, Far Earlier Than Expected

Brazilian 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 [...]

Model Based on Hydrothermal Sources And The Possibility of Life on Europa
Publicado em 26 fevereiro 2018Jupiter's icy moon Europa is a major target of astrobiology research in light of the possibility that it offers a habitable environment in the Solar System. Under its ice crust, estimated to be 10 km thick, is an ocean of liquid water of over 100 km deep. A huge source of energy deriving from gravitational interaction with Jupiter keeps this water warm. Theoretical research to evaluate the microbial habitability of Europa using data collected from analogous environments on Earth has been [...]ver notícia -
The Origin Of Earth's Water
Publicado em 16 novembro 2017A New Physical Model Explains The Origin Of Earth's Water. Equipped with Newton's law of universal gravitation (published in Principia 330 years ago) and powerful computational resources (used to apply the law to more than 10,000 interacting bodies), a young Brazilian researcher and his former postdoctoral supervisor have just proposed a new physical model to explain the origin of water on Earth and the other Earth-like objects in the Solar System. André Izidoro, from the School of [...]ver notícia
