Article signed by researchers affiliated with institutions in the US, UK, Ghana and Brazil highlights recent progress in diagnosis and treatment but warns that more screening of newborns is needed The promise of new treatments for sickle cell disease, a group of inherited red blood cell disorders, has never been so great, but it will only be realized if there is constant investment in health policies such as programs for screening newborns, especially in sub-Saharan Africa, where most cases [...]

Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought. The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923?base pairs. The human mitochondrial genome (mitogenome), for example, comprises 16,569 base pairs. Tube anemones (Ceriantharia) are the focus of an article recently published in Scientific Reports [...]

A study by the FAPESP-funded Research, Innovation and Dissemination Center shows that toxins produced by young female stingrays cause more pain, whereas toxins produced by adult stingrays cause tissue necrosis There is no antidote or specific treatment for freshwater stingray venom, although accidents involving these animals are frequent on rivers in the Amazon and other regions. A groundbreaking study conducted at the Butantan Institute in São Paulo, Brazil, analyzed freshwater [...]

This phenomenon affects cloud production and rainfall, with consequences for the local and global climate, which researchers have warned about in the study published in Nature Communications A study by an international team of researchers, including Brazilian scientists, shows that urban pollution from Manaus, the capital of Amazonas State in Brazil, increases the formation of aerosols via the Amazon Rainforest far more than expected. This sharp increase in aerosols produced by the forest has [...]

A nonlethal dose of insecticide clothianidin can reduce honeybees’ life span by half; once combined with the fungicide pyraclostrobin, it alters the behavior of worker bees to the point of endangering the whole colony. A new study by Brazilian biologists suggests that the effect of pesticides on bees could be worse than previously thought. Even when used at a level considered nonlethal, an insecticide curtailed the lives of bees by up to 50%. The researchers also found that a fungicide [...]

With the aim of enhancing the quality of Brazilian space research output, scientists investigated the accuracy of different satellite data collections A study conducted by scientists from Brazil, the United States and Portugal investigated the accuracy and consistency of different satellite data collections with regard to the location and size of burned areas in the Cerrado biome, the Brazilian savanna. The results, published in the International Journal of Applied Earth Observation and [...]

A study performed in Brazil by researchers from São Paulo State University (UNESP) suggests that overweight and obese adolescents have similar increased risks of developing heart disorders. The results of cardiovascular fitness tests with volunteers aged 10-17 were similar in both groups. Supported by São Paulo Research Foundation – FAPESP, the results of the study were published in the journal Cardiology in the Young. The investigation also featured collaboration with [...]

As well as causing significant harm to human health, air pollution also stunts the growth of trees, one of the very elements that can attenuate this typically urban environmental problem. Researchers at the University of São Paulo (USP) in Brazil have shown that atmospheric pollutants restrict tree growth and the ecosystem services provided by trees, such as filtering pollution by absorbing airborne metals in their bark, assimilating CO2, reducing the heat island effect by attenuating [...]

Measuring the blood plasma levels of an enzyme called PDIA1 could one day become a method of diagnosing a person's predisposition to cardiovascular disease even if they are healthy, i.e., not obese, diabetic or a smoker, and with normal cholesterol. This is suggested by a study published in the journal Redox Biology by Brazilian researchers affiliated with the University of São Paulo (USP), the University of Campinas (UNICAMP) and Butantan Institute. The investigation was conducted [...]
