Study shows that Rio Grande Rise was once a giant mineral-rich tropical island near Brazil
Publicado em 01 de fevereiro de 2024
A study led by scientists at the University of São Paulo (USP) in Brazil has shown that the Rio Grande Rise (RGR), a possibly continental basaltic plateau and chain of seamounts now submerged in the South Atlantic Ocean some 1,200 km from the coast of Brazil, was once a giant tropical island, rich in minerals and covered with vegetation. Geologists have dated sediments from the formation to between 45 million and 40 million years ago.
The study, which involved almost 10 years of [...]

Researchers propose conditions for maximizing quantum entanglement
Publicado em 04 janeiro 2024Quantum entanglement is a fundamental concept in quantum mechanics that has fascinated scientists for decades. It refers to the phenomenon where two or more particles become correlated in such a way that the state of one particle cannot be described independently of the state of the other particles. Recently, a group of researchers has proposed a set of conditions that can maximize the degree of entanglement between particles. These conditions, outlined in a paper published in the [...]ver notícia -
Incomplete Notification and Underreporting of Snakebites Can Hinder Public Health Actions, Study Suggests
Publicado em 04 janeiro 2024Snakebites are a significant public health concern in many parts of the world, particularly in rural areas where access to healthcare may be limited. However, a recent study suggests that incomplete notification and underreporting of snakebites can hinder effective public health actions. The Problem of Incomplete Notification In many countries, snakebite cases are not consistently reported to public health authorities. This lack of notification can lead to a distorted understanding of the [...]ver notícia -
