Brazilian researchers have proposed an elegant solution to a long-standing physics debate, suggesting that in our relativistic universe, everything could theoretically be measured using just a single unit: time. This finding challenges decades of conventional thinking about how we measure the physical world. Published in Nature Scientific Reports The research team, comprising scientists from multiple Brazilian institutions, has tackled a fundamental question that sparked debate among [...]

A team of Brazilian researchers has demonstrated that a common food coloring derived from the tropical achiote plant, combined with blue light therapy, could offer an effective and accessible treatment for chronic bad breath in children who breathe through their mouths. This innovative approach could provide dentists with an affordable alternative to traditional treatments, potentially improving quality of life for affected children during crucial developmental years. Published in PLOS ONE | [...]

Brazilian researchers have reconstructed the tree of life from the evolutionary history of amoebas and other organisms, revealing a surprisingly diverse ecosystem during the Neoproterozoic era. Summary: New research suggests that Earth's biodiversity 800 million years ago was more complex than classical theory indicates, with multiple lineages of eukaryotes surviving through major climate events. Estimated reading time: 5 minutes A study published in the Proceedings of the National [...]

The event that wiped out the dinosaurs wasn't all bad. The low-light environment caused by the meteor impact some 66 million years ago favored the   spread of fungi that feed on organic matter, which was abundant at the time as plants and animals were dying in droves. It was the perfect opportunity for the ancestor of a group of ants to start cultivating these microorganisms, according to a study published on October 3 in the journal Science “The origin of [...]

A new study has uncovered the physiological mechanism behind the ability of Salvator merianae, the Black and white tegu lizard, to raise its body temperature independently during the mating season. This discovery raises questions about long-held beliefs regarding reptilian thermoregulation and the distinctions between cold-blooded and warm-blooded animals. Unraveling the Tegu's Thermal Adaptation Researchers from São Paulo State University's School of Agrarian and [...]

Researchers at the University of São Paulo (USP) in Brazil have discovered that SARS-CoV-2, the virus responsible for COVID-19, can remain in the sperm of patients for up to 90 days after hospital discharge and up to 110 days after the initial infection. The study, published in the journal Andrology, is the first to demonstrate this prolonged presence of the virus in semen, which can lead to reduced sperm quality. The findings suggest that individuals planning to have children should [...]

Researchers from the University of California, Los Angeles (UCLA) and the Federal University of the ABC (UFABC) in São Bernardo do Campo, São Paulo state (Brazil) have identified a group of neurons deep in the brain that are directly associated with compulsive eating and food craving. The discovery, reported in an article published in Nature Communications, sheds light on the neural mechanisms behind eating disorders and could lead to the development of novel treatment [...]

In 1998, they found something even more surprising: the expansion is speeding up, not slowing down like they thought it would. This led to the idea of [...]
