Brazilian researchers have developed a ceramic clay that is lighter than that normally used in civil construction by adding algae from the Sargassum genus to the manufacturing process. These brown algae, also known as sargassum, are common in the central Atlantic Ocean. However, they have been washing up in large quantities on beaches in the Caribbean, the United States, and northern Brazil, where they have become problematic. Their accumulation on beaches can harm human health due to the [...]

A set of bones belonging to sauropods, as long-necked dinosaurs are called, found in the municipality of Ibirá in the state of São Paulo, Brazil, reveals that the region was conducive to a bone disease that was fatal to these animals. Supported by FAPESP, the researchers found signs of osteomyelitis, a bone disease that can be caused by bacteria, viruses, fungi, or protozoa, in the fossils of six individuals from the Cretaceous period, approximately 80 million years [...]

A study conducted by researchers from the Pennington Biomedical Research Center ( PBRC , United States), Proteimax Biotechnology (Israel), and the University of São Paulo's Biomedical Sciences Institute ( ICB-USP , Brazil) showed that ingesting Pep19 helps reduce visceral fat and improve sleep in obese adults. The molecule is a synthetic version of a peptide (a very small piece of protein) naturally found in human cells. Previous studies on animals have [...]

Several studies have shown that students who attend afternoon classes tend to perform better in school than those who attend morning classes. This is due to greater synchrony between class times and students' biological clocks. However, a study of children and adolescents revealed that this does not apply to students with attention deficit hyperactivity disorder (ADHD) or symptoms of the condition. For this group, changing school shifts does not significantly improve academic [...]

A new species of bacteria of the genus Bartonella has been found in the Amazon National Park in the state of Pará, Brazil, in phlebotomine insects, also known as sand flies. This type of insect is generally associated with transmitting leishmaniasis, but according to the researchers, the DNA of the newly discovered microorganism is similar to that of two other Andean species of bacteria, B. bacilliformis and B. ancashensis. These bacteria cause Carrión's disease (also known as [...]

The COVID-19 virus hijacks the machinery of testicular cells that produce the hormone testosterone in order to replicate. It also appropriates the metabolic pathways of these cells and cholesterol, a precursor of testosterone, thereby altering lipid metabolism for its formation. This was verified in a study conducted in Brazil by researchers from the Araraquara School of Dentistry at São Paulo State University (FOAr-UNESP), in partnership with the Ribeirão Preto School of Medicine [...]

As deforestation and climate change threaten to transform the Amazon, there is growing concern that the ecosystem may be reaching an irreversible tipping point, beyond which self-reinforcing feedback loops would lock the system in a degraded state and lead to the Amazon flipping from a carbon sink to a carbon emitter. However, a new study , led by Yale School of the Environment scientists, found that there is no evidence of a single, basin-wide tipping point. Instead, there is [...]
