Brazil has two populations of American bullfrogs, an exotic species that transmits a deadly fungus
Publicado em 08 de setembro de 2022
Researchers at the University of São Paulo (USP) and the State University of Campinas (UNICAMP) have conducted the most comprehensive genetic analysis ever of the American bullfrog (Aquarana catesbeiana) in Brazil, concluding that there are two populations of the species here, living on frog farms or invading local ecosystems. Bullfrogs are considered the world’s main invasive amphibian.
An article on the study is published in Scientific Reports.

Ceres Probably Formed Farther out in the Solar System and Migrated Inward
Publicado em 18 maio 2022When Sicilian astronomer Giuseppe Piazzi spotted Ceres in 1801, he thought it was a planet. Astronomers did not know about asteroids at that time. Now we know there’s an enormous quantity of them, primarily residing in the main asteroid belt between Mars and Jupiter. Ceres is about 1,000 km in diameter and accounts for a third of the mass in the main asteroid belt. It dwarfs most of the other bodies in the belt. Now we know that it’s a planet — albeit a dwarf one — [...]ver notícia -
Gene Therapy Reverses Effects of Autism-Linked Mutation in Brain Organoids
Publicado em 02 maio 2022Summary: A brain organoid study reveals how a genetic mutation associated with Pitt-Hopkins syndrome, a profound form of autism, disrupts neural development. Using gene-editing technology, researchers recovered the function of the TCF4 gene and effectively restored neural structure and function. Source: UCSD In a study published in Nature Communicationsscientists at University of California San Diego School of Medicine used human brain organoids to reveal how a genetic [...]ver notícia
