Evaluating body composition, particularly appendicular muscle mass, can be an effective approach for predicting longevity in people over 65 years of age, reports a new study. The findings of the study are published in the Journal of Bone and Mineral Research. The researchers studied a group of 839 men and women over the age of 65 for approximately four years. They observed that all-cause mortality risk increased nearly 63-fold during the follow-up period in women with low appendicular muscle [...]

Evaluating physique composition, particularly appendicular muscle mass, will be an efficient technique for predicting longevity in individuals over 65 years of age, in response to a research performed by researchers on the College of São Paulo’s Medical College (FM-USP) in Brazil. The appendicular muscular tissues are the muscular tissues that transfer the appendages or extremities – the legs and arms. Additionally they play a key function in stabilizing the shoulders and [...]

Cannabidiol reduces the aggressiveness induced by social isolation, according to a study done by scientists at the University of São Paulo's Ribeirão Preto Medical School (FMRP-USP) in Brazil in a mouse. The results are published in the journal Progress in Neuro-Psychopharmacology and Biological Psychiatry. "Our study shows that cannabidiol can inhibit aggressiveness and that it does so by facilitating the activation of two receptors: the 5-HT1A receptor, responsible for [...]

Skipping breakfast, a common habit among teenagers is associated directly with increased waist circumference and body mass index (BMI). The habit can lead to an unbalanced diet, other unhealthy behaviors, potentially making the teens vulnerable to weight gain, reports a new study. The findings of the study are published in the journal Scientific Reports. New study describes how researchers affiliated with the University of São Paulo's Medical School (FM-USP) in Brazil and colleagues [...]

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 pollination which [...]

Inclusion of a parameter that measures an animal's capacity to transmit its genetic traits resulted in gains of up to 16% compared with a traditional method of selection Brazilian scientists at São Paulo State University (UNESP) collaborating with colleagues at the University of Maryland and the United States Department of Agriculture (USDA) have developed a dairy cattle breeding method that adds a new parameter to genetic selection and conserves or even improves a population's [...]

Plants in the Brazilian savanna, the Cerrado, have evolved to deal with the fire. When the fire is used intelligently as part of a carefully planned land management method, it is indispensable to the conservation of this superb ecosystem, the world's most biodiverse savanna. Two months suffice for the Cerrado to burst into flower after a fire The study "From ashes to flowers: a savanna sedge initiates flowers 24 h after fire", published recently in the journal Ecology, confirms [...]

A new £620,000 study led by the University of Stirling is taking a "revolutionary approach" in attempting to tackle resistance to pesticides in insects. Pesticide resistance is a serious problem for the agriculture industry worldwide, with pests consuming between 10 and 20 percent of all global crops while growing or in storage. The study will focus on Brazil, where the agricultural economy loses approximately $17.7 billion (£13.6 billion) a year to outbreaks of insects [...]
