Computer models allow farmers to diversify pest management methods
Publicado em 20 fevereiro 2018Date: February 20, 2018 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: A technology developed by Brazilian researchers can help fighting highly resistant agricultural pests by analyzing the connections between the pests' patterns of dispersal in crops and different configurations in diversified intercropping systems. The Fall armyworm (Spodoptera frugiperda), a lepidopteran pest that feeds on leaves and stems of as many as 100 plant species, is able to hop between [...]ver notícia -

International study identify the process of rock formed by meteors or nuclear blasts
Publicado em 16 janeiro 2018Date: January 16, 2018 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Scientists have made a model to map out the phases in which silica (SiO2) transforms into coesite, by analyzing how the inelastic scattering of light among molecules changes according to pressure variation. Scientists from Brazil, China and Italy have developed a model to map out the phases in which silica (SiO2) transforms into coesite rock, by analyzing how the inelastic scattering of light [...]ver notícia -

Possible vestiges of a universe previous to the Big Bang
Publicado em 27 novembro 2017Date: November 27, 2017 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: A researcher proposes to eliminate the need for cosmological space-time singularity and argues that the current expansion phase was preceded by contraction. Although for five decades, the Big Bang theory has been the best known and most accepted explanation for the beginning and evolution of the Universe, it is hardly a consensus among scientists. Brazilian physicist Juliano Cesar Silva Neves [...]ver notícia -
Little-known fruits contain powerful anti-inflammatory and anti-oxidant agents
Publicado em 31 outubro 2017Research shows that five fruit species native to Brazil's Atlantic Rainforest biome have bioactive properties as outstanding as those of blueberries, cranberries, blackberries, and strawberries. By investigating the presence of anti-aging nutrients that also work at the prevention of cancer, diabetes and Alzheimer's, the study clears the path for the conservation and promotion of the genus Eugenia, which contains 400 species (some of them endangered) and presents huge potential in food and pharmaceutical industriesver notícia -
Less fat, more hair and younger skin: Study in mice shows benefits from calorie-restricted diet
Publicado em 30 outubro 2017Fundação de Amparo à Pesquisa do Estado de São Paulo Scientists show that mice subjected to the diet presented body fat reduction and fur production increase. The research group also noted that liver, pancreas and brain cells from these mice boasted a higher performance in activities related to metabolic regulation. Caloric restriction diets have been associated with various health benefits, but their effects on the skin have not been previously demonstrated. Research conducted at the [...]ver notícia
