By creating a new metric, researchers envision the possibility of diagnostic and treatment advances for the disease, which is estimated to affect about 4 million people worldwide.
Climate change on the prehistoric Iberian Peninsula caused the loss of midsized prey and reduced the supply of food for carnivores, making them more likely to disappear. A study based on fossil records warns of the cascading effect of extinctions in the present.
A study of 153 people between the ages of 60 and 89 suggests modifications to a well-established clinical test for assessing balance in the elderly to make it more efficient, accessible, and predictive.
Less studied than grasses and trees, these plant species are of enormous importance to the Brazilian savannah biome in terms of biodiversity, carbon storage, regeneration after disturbance, and the provision of ecosystem services such as food and medicine.
Researchers at a FAPESP-supported research center have identified the key role of the GenB2 enzyme in the formation of gentamicin components. The findings make it possible to develop safer and more selective versions of the drug.
A technology that uses unmanned aerial vehicles developed by a FAPESP-supported startup has enabled Brazil’s leading cosmetics company to complete in six months a census of six species of key importance to its production process distributed across 40,000 hectares of forest in the Amazon.
In a review article, researchers highlight the importance of metrology institutions in setting standards to characterize biopolymers and avoid greenwashing – a marketing practice that deceptively promotes products as being environmentally friendly.
The phase 3 clinical trial showed that Butantan-DV is effective against dengue virus types 1 and 2, which were circulating at the time. The results can be extrapolated for types 3 and 4 based on additional in vitro testing, according to the researchers.
The method converts the vinasse left over from ethanol production into a potassium- and nitrogen-rich fertilizer. The groundbreaking study was conducted at the Federal University of São Carlos and published in the Journal of Environmental Management.
Researchers from the Center for the Development of Functional Materials have found that the material is promising for use in processes to produce hydrogen using solar energy.
Using a single-cell sequencing technique, it was possible to characterize the different cell types present in the brain lesion. The result paves the way for specific treatments against focal cortical dysplasia.
Brazilian and British researchers have observed that a small crustacean that changes color according to the marine vegetation is able to disguise itself in exotic algae that did not evolve together with the species. However, the long-term effects of this interaction are unknown.
Scientists at the University of São Paulo analyzed blood samples donated by six serodiscordant couples where female partners were resistant to SARS-CoV-2 despite intense contact with their infected male partners.
