Cutting protein intake can help control metabolic syndrome and some of its main symptoms, such as obesity, diabetes and high blood pressure (hypertension), according to a study conducted by researchers in Brazil and Denmark to compare the effects of protein and calorie restriction diets in humans. An article reporting the study is published in the journal Nutrients. Metabolic syndrome is a cluster of conditions that heighten the risk of cardiovascular disease, stroke and [...]

The countless benefits of native forests include the capacity of tree biomass to store large amounts of carbon, which can counterbalance greenhouse gas emissions into the atmosphere. A paper published in the journal Science Advances reports on an innovative analysis of a large dataset designed to clarify the concept of carbon sequestration, a strategic issue in the discussion of global climate change. “We still know little about the factors that can lead forests to [...]

Every day we inhale thousands of potentially pathogenic fungal spores, but our immune system simply eliminates them. However, in people with compromised immunity, such as transplant and cancer patients, as well as hospitalized patients in intensive care, the interaction between pathogen and host may be quite different. Fungal infections that emerged during the COVID-19 pandemic, reinforcing the action of SARS-CoV-2 around the world, are a case in point. Mortality reached 80% among severe [...]

Researchers at the University of São Paulo (USP) and the State University of Campinas (UNICAMP) have conducted the most comprehensive genetic analysis ever of the American bullfrog (Aquarana catesbeiana) in Brazil, concluding that there are two populations of the species here, living on frog farms or invading local ecosystems. Bullfrogs are considered the world’s main invasive amphibian. Researchers at the University of São Paulo (USP) and the State University of Campinas [...]

A study published in the journal PLOS ONE could one day help health workers determine whether bacteria of the species Streptococcus pneumoniae, which cause meningitis – an inflammation of the membranes that envelop the brain and spinal cord – are resistant to antibiotics.

The process of selecting specialty coffee beans entails three kinds of inspection. Two are physical and involve samples of raw and roast coffee. The third is sensory and involves tasting the drink. Certification is provided by the Specialty Coffee Association of America (SCAA). The process of selecting specialty coffee beans entails three kinds of inspection. Two are physical and involve samples of raw and roast coffee. The third is sensory and involves tasting the drink. Certification is [...]

A study by researchers at the Federal University of São Carlos (UFSCar) in Brazil and University College London (UCL) in the United Kingdom shows that a combination of anemia and weak muscles in older people heightens the risk of death in ten years by 64% for men and by 117% for women. Anemia alone increases the risk of dying by 58% in men. For women, dynapenia (loss of muscle strength) is a more important risk factor on its own, increasing the risk of death by 68%. The two conditions [...]

A study conducted by researchers in Brazil, Australia, Austria and the United States has made significant discoveries about a type of pediatric cancer with no approved drugs for treatment and with a low survival rate. The findings, described in an article published in the journal Neuro-Oncology, pave the way for a search for more specific therapies. A study conducted by researchers in Brazil, Australia, Austria and the United States has made significant discoveries about a type of pediatric [...]

Using a method based on satellite images and artificial intelligence, Brazilian researchers have shown that the priority area for actions to combat illegal deforestation could comprise 27.8% less territory than the 11 municipalities monitored by the federal government under the current strategy, known as the Amazon Plan 2021/2022. This monitoring ignores new deforestation frontiers outside the targeted areas. Using a method based on satellite images and artificial intelligence, Brazilian [...]
