A major budget crisis at Brazil’s leading science funding agency could disrupt the lives of thousands of students and early-career scientists. In September, the National Council for Scientific and Technological Development (CNPq) in Brasília could run out of money to continue to fund the grants and scholarships it provides to more than Brazilians. On 15 August, the agency took to Twitter to announce the suspension of financial support for its recipients—a measure that many [...]

Researchers and caregivers have famous that excessive daytime sound asleep can expand lengthy earlier than the reminiscence complications linked to Alzheimer's disease start to spread. Prior reports have regarded this excessive daylight drowsing to be compensation for poor midnight sleep led to via Alzheimer's-associated disruptions in sleep-advertising mind regions, at the same time as others have argued that the sleep problems themselves give a contribution to the development of the [...]

Un study with key contributions from Brazilian researchers shows that an endangered species, famed as a “forest gardener,” influences African forest composition in terms of tree species and increases the aboveground biomass over the long term The African forest elephant (Loxodonta cyclotis), an endangered species, is often referred to as a “gardener” in recognition of its role as a disperser of fruit seeds from the large diversity of trees it feeds on as it moves [...]

A system created in Brazil using cheap, biodegradable materials permits controlled release of larvicide and can be used in small amounts of water Corn starch, an abundant, cheap and biodegradable raw material, is the basis for a novel larvicide developed by researchers at the University of Campinas (UNICAMP) in São Paulo State, Brazil. The material is used in microcapsules for storage and controlled release of active compounds to kill larvae of Aedes aegypti, the mosquito that transmits [...]

A study of individuals over 65 years old showed that all-cause mortality risk increased nearly 63-fold in women with low appendicular muscle mass. The risk of dying increased 11.4-fold in men (patient undergoing DXA body composition and bone density scan. Evaluating body composition, especially appendicular muscle mass, can be an effective strategy for predicting longevity in people over 65 years of age, according to a study conducted by researchers at the University of São [...]

Experiments with mice performed by Brazilian scientists show that a substance derived from cannabis plants attenuates isolation-induced aggressive behavior. A new study has concluded that cannabidiol attenuates the aggressiveness induced by social isolation. The research, based on a mouse model, was performed by scientists at the University of São Paulo’s Ribeirão Preto Medical School (FMRP-USP) in Brazil. The results are published in the journal Progress in [...]

This study investigated behaviors associated with weight gain and cardiometabolic risk in adolescents. Missing the first meal of the day can contribute to the development of unhealthy habits and behaviors A paper published in Scientific Reports describes how researchers affiliated with the University of São Paulo’s Medical School (FM-USP) in Brazil and colleagues at institutions in Europe evaluated behaviors leading to weight gain in adolescents. Childhood obesity can favor the [...]

The aggressiveness of ants in arid environments with scarce food supply helps protect plants against herbivorous arthropods Biologists Laura Carolina Leal and Felipe Passos performed a series of experiments in Brazil’s Northeast region – specifically in the interior of Bahia State, where the semiarid Caatinga biome predominates – to determine how plants with extrafloral nectaries interact with ants. Extrafloral nectaries are nectar-secreting glands not involved in [...]

Researchers find that substances synthesized from plant species endemic to the biodiversity hotspot can kill the parasites that cause these neglected diseases
