Washington DC [US], November 10 (ANI): Researchers at the University of Sao Paulo (USP) in Brazil, in collaboration with colleagues in Australia, discovered a unique bacterial protein that can maintain human cells healthy even when the cells are heavily contaminated with bacteria. The discovery could lead to new treatments for a wide range of mitochondrial dysfunction-related ailments, including cancer and auto-immune disorders. Mitochondria are organelles that provide the majority of the [...]

Washington DC [US], August 30 (ANI): A review paper published in the journal Foods describes a study that provides an overview of studies on minimally processed vegetables (MPVs), with a particular focus on the Brazilian market. Data is presented on hygiene indicators and pathogenic microorganisms, especially Escherichia coli (the main indicator of fecal contamination), Salmonella spp., and Listeria monocytogenes, with prevalence rates ranging from 0.7 per cent to 100 per cent, 0.6 per cent [...]

Washington [US], August 20 (ANI): According to a study, artificial intelligence can make a diagnosis of autism spectrum disorder.  ‘Scientific Reports’ is a journal that published the study. Due to the intricacy of the condition, diagnosing autism spectrum disorder (ASD) still presents a difficult issue that calls for highly qualified clinicians. Multifactorial neurodevelopmental disorder autism has a wide range of symptoms. The study was based on brain imaging data [...]

Washington [US], August 15 (ANI): A study has found that artificial intelligence can diagnose autism spectrum disorder. The study was published in the journal, ‘Scientific Reports’. Diagnosing autism spectrum disorder (ASD) is still a daunting challenge because of the degree of complexity involved, requiring highly specialized professionals. Autism is a multifactorial neurodevelopment disorder with widely varying symptoms. The study was based on brain imaging data for 500 [...]

Washington [US], May 6 (ANI): Millions of Amerindians living in today’s Amazonia altered the formerly poor soil through numerous mechanisms between 450 BCE and 950 CE. Soils were enhanced with charcoal from low-intensity fires used for cooking and burning trash, animal bones, broken pottery, compost, and manure through many human generations. The end product is Amazonian dark earth (ADE) or terra preta, which is extremely fruitful due to its high concentration of nutrients and stable [...]

Washington [US], March 8 (ANI): Dinosaurs as big as buses or five-story buildings would not be possible if their bones were dense and heavy like ours. Like present-day birds, dinosaurs had hollow bones with inner structures known as air sacs, which made their skeletons lighter and less dense. These structures were apparently so advantageous that they emerged at least three times during the evolution of dinosaurs and pterosaurs (flying reptiles), according to a study supported by FAPESP and [...]

Washington [US], January 6 (ANI): Exercise may be the most powerful anti-aging intervention known to science and has been proven to protect against a wide array of diseases. However, while physical activity can improve health during aging, its beneficial effects inevitably decline. The cellular mechanisms underlying the relationship between exercise, fitness, and aging remain poorly understood. In a paper published in the Proceedings of the National Academy of Sciences, researchers at [...]

Rapid, low-cost, and accurate tests are still required for epidemiological surveillance and healthcare services to monitor and contain the spread of SARS-CoV-2. Brazilian researchers have contributed to this field’s efforts by creating an electrochemical immunosensor that identifies antibodies against the virus. The innovation is described in an article published in the journal ACS Biomaterials Science and Engineering. In search of a novel diagnostic method, the group opted for a [...]

Washington [US], November 18 (ANI): Capuchin monkeys (Sapajus spp.) are among only a few primates that use tools in day-to-day activities. In the Cerrado and Caatinga, they use stones as hammers and anvils to crack open cashew nuts, seed pods of Hymenaea courbaril (West Indian locust; jatoba in Brazil) and other hard foods. In an article published in Scientific Reports, Brazilian researchers show that food hardness and tool size do not always correlate as closely as has been thought. In [...]
