Poaching affects behavior of endangered capuchin monkeys in Brazilian biological reserve
Publicado em 22 junho 2021
A study conducted in the Una Biological Reserve in the state of Bahia, Brazil, shows that in a habitat with high hunting pressure the risk of predation has such a significant impact on the behavior of the Yellow-breasted capuchin monkey Sapajus xanthosternos that it even avoids areas offering an abundant supply of plant biomass and invertebrates, its main sources of food.
An article reporting the findings of the study is published in the American Journal of [...]

Immune system dysfunction can modify the association between cannabis use and psychosis
Publicado em 16 junho 2021The presence of pro-inflammatory cytokines in the blood can boost the effects of daily cannabis use and heighten the risk of developing psychosis in adulthood. Similar results have been observed, also in the presence of cytokines, when cannabis is used during adolescence. Psychotic disorders have symptoms such as delirium, loss of a sense of reality, hallucinations, hearing voices, and cognitive and social impairments. A study by researchers at the University of São Paulo’s [...]ver notícia -
Researchers identify the causes of the extreme drought that affected the Pantanal
Publicado em 24 maio 2021The extreme drought suffered by the Pantanal in 2019-20, considered the worst in the last 50 years, was caused by natural climate conditions similar to those underlying the 2014-16 water crisis in São Paulo state. The Pantanal is one of the world's largest wetlands. The Brazilian portion is located in the Center-West region, mainly Mato Grosso do Sul state. The 2019-20 extreme drought was studied by researchers affiliated with the Natural Disaster Surveillance and Early Warning [...]ver notícia -
Vegan and omnivorous diets promote equivalent muscle mass gain, study shows
Publicado em 19 maio 2021Protein intake is more important than protein source if the goal is to gain muscle strength and mass. This is the key finding of a study that compared the effects of strength training in volunteers with a vegan or omnivorous diet, both with protein content considered adequate. In the study, which was conducted by researchers at the University of São Paulo (USP) in Brazil, 38 healthy young adults, half of whom were vegans and half omnivores, were monitored for 12 weeks. In addition to [...]ver notícia -
Phenomenon explains why patients who survive sepsis die sooner after hospital discharge
Publicado em 12 maio 2021An article published in Frontiers in Immunology suggests that sepsis can cause alterations in the functioning of defense cells that persist even after the patient is discharged from hospital. This cellular reprogramming creates a disorder the authors call post-sepsis syndrome, whose symptoms include frequent reinfections, cardiovascular alterations, cognitive disabilities, declining physical functions, and poor quality of life. The phenomenon explains why so many patients who survive sepsis die [...]ver notícia -
Soybean and linseed oils added to cows’ diet improve the quality of milk
Publicado em 09 maio 2021Inclusion of soybean and linseed oils in the diet of dairy cows made the fatty acid content of their milk even healthier for human nutrition. It also increased the proportions of omega-6 and omega-3, which in the right balance play a key role in preventing cardiovascular diseases, for example, as well as chronic inflammation and some kinds of cancer. Cardiovascular diseases are one of the world’s main public health problems. In Brazil, they are among the foremost causes of death. Each [...]ver notícia -

Computer simulation helps understanding the transport of aerosols
Publicado em 25 novembro 2019One of the speakers at FAPESP Week France, held in Lyon and Paris until November 27th, Livia Freire, a researcher at the Institute of Mathematical and Computing Sciences of the University of São Paulo (ICMC-USP), has been developing computer simulations to try to broaden the knowledge on the transport of aerosols. “Our interest lies in knowing how these particles are transported by atmospheric flows, which are very complicated movements to simulate and understand, because they are [...]ver notícia -
Niobium used as catalyst in fuel cell
Publicado em 24 novembro 2019Brazil is the world’s largest producer of niobium and holds about 98% of the active reserves on the planet. This chemical element is used in metal alloys, especially high-strength steel, and in an almost unlimited array of high-tech applications from cell phones to aircraft engines. Brazil exports most of the niobium it produces in the form of commodities such as ferroniobium. Another substance Brazil also has in copious quantities but underuses is glycerol, a byproduct of oil and fat [...]ver notícia -
Discovery Paves The Way For Blocking Malaria Transmission In Brazil
Publicado em 22 novembro 2019Research suggests that bacteria present in the intestine of the Anhopheles darlingi mosquito influence the development of the parasite that causes the disease in the insect’s body and the chances of transmission to humans The bacteria that form the gut microbiota influence important processes of the human body, such as digestion, nutrient absorption, and defense against pathogens. The same type of relationship is present in most animals, including in the Anhopheles darlingi mosquito, the [...]ver notícia
