Acetone, a key input for the chemical industry, is traditionally manufactured through a complex and risky procedure. Researchers from Brazil and Germany have collectively forged a more eco-friendly approach. Acetone plays a pivotal role in the chemical industry, serving as a critical component in the creation of diverse products including adhesives, antibiotics, electronic parts, solvents, paint removers, inks, and vitamins. However, its production is complex and hazardous. To simplify the [...]

In a study involving 46 participants, it was discovered that individuals with untreated obstructive sleep apnea experienced faster telomere shortening, an indicator of cell aging. However, the use of continuous positive airway pressure reduced this damage. Obstructive sleep apnea (OSA) is characterized by repeated episodes of the upper airway partially or fully closing during sleep. This leads to pauses in breathing that can last from a few seconds to several minutes, often followed by [...]

Research indicates that Amazon dark earth (ADE) promotes tree growth by as much as sixfold. The study demonstrated that tree seedlings grown in ADE-enriched soils saw exponential growth compared to control soils. A type of soil called terra preta da Amazônia , or Amazon dark earth (ADE), promotes faster growth of trees and enhances their development in qualitative terms, according to an article published in the journal Frontiers in Soil Science “ADE is rich in nutrients and [...]

Bone cavities called air sacs emerged in the precursors of long-necked dinosaurs around 225 million years ago, according to the analysis of a specimen found in Rio Grande do Sul state, South Brazil. The missing link has just been found, bridging the gap between the earliest dinosaurs, which varied significantly in size from mere centimeters to a maximum of 3 meters, and more recent giants that could be more than twice the length of a bus and have so much appeal to the popular [...]

Researchers at Brigham are developing a new approach that uses engineered bacteria to more safely and effectively treat autoimmune conditions in the brain. Brigham researchers are developing a novel method to address autoimmunity in the brain by utilizing engineered bacteria to enhance both the safety and effectiveness of the treatment. Researchers from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, have developed a probiotic [...]

A study, conducted across four distinct regions of Brazil, performed genomic data analysis of 34 fossils, comprising larger skeletal remains as well as the renowned coastal mounds of shells and fishbones. This research revealed differences between communities. A recent paper published in the journal Nature Ecology & Evolution presents evidence suggesting that Luzio, the most ancient human skeleton discovered in the state of São Paulo, Brazil, descended from the original population [...]

A study has indicated that the hormone, which is readily available for purchase from drugstores and frequently used as a supplement, intensified the symptoms of Crohn's disease and ulcerative colitis in laboratory mice. The effect, however, depended on the animal's gut microbiota profile. A new study recently published in the journal Microorganisms shows that melatonin, despite its antioxidant properties and role in sleep cycle regulation, could intensify intestinal inflammation and [...]

Experiments involving mice showed four weeks of training with weights to be sufficient to reverse behavioral and physical alterations characteristic of the disease. Regular physical exercise, such as resistance training, can prevent Alzheimer's disease, or at least delay the appearance of symptoms, and serves as a simple and affordable therapy for Alzheimer's patients. This is the conclusion of an article published in the journal Frontiers in Neuroscience by Brazilian researchers [...]
