A Brazilian study identified more than 74,000 active fires in the period. They were not mainly due to extreme drought, the foremost cause of the spate of forest fires seen in 2010. Half of the Amazon is typically vulnerable to fire in the two-month period analyzed. Human action was the main cause of the recent destruction.

Wildcat prospecting has expanded faster since 2017 and occurs mainly on the Kayapó, Munduruku and Yanomami reservations, according to a study by scientists at Brazil’s National Space Research Institute.

A book chapter by researchers at the Federal University of the ABC shows that scant progress has been achieved in addressing the concentration of land tenure in Brazil since the return to civilian rule in 1985. For the authors, extreme inequality and a lack of public policies to combat it are the main causes of rural conflict and violence.

First study to identify pixel and voxel organizational parameters in MRI scans of two different (albeit similar) benign tumors may contribute to development of more accurate, less invasive diagnosis.

The study cross-referenced datasets on 140 native species in the world’s largest dry tropical forest, located mainly in Bolivia and Argentina, with patches in Paraguay and Brazil. The wetter north has more tree-dwelling snakes, while most species have adapted to living underground in burrows in the drier south.

Topics that will be covered include processing of high-resolution image data, single particle analysis, and in-cell structural biology by cryo electron tomography (Cryo-TM). Applications are due on March 06, 2023.

A study by Brazilian researchers shows that the use of bioenergy avoids greenhouse gas emissions. Another benefit of their bioreactor is conversion of apple pomace into organic fertilizer.

Cetuximab is one of the few drugs approved for this type of cancer, but it is expensive and effective only for 40% of patients. An article in the journal Cells describes molecular alterations observed in tumor cells that indicate resistance to the drug, paving the way to the development of a predictive test.

Using experimental fires set at different times of year in the Campos Amazônicos National Park, Brazilian researchers found that lags in acquiring and assessing information obtained from satellite imaging can lead to misinterpretation. The study points to the need for adjustments to monitoring algorithms.

In a Brazilian study involving 800 children, researchers found that extended breastfeeding protects the baby’s teeth as long as it is not given sugary food.

Based on an analysis of data for nearly 1,000 participants in the English Longitudinal Study of Ageing born in the 1950s and 1960s, researchers concluded that children’s relationships with parents influence longevity, although the impact is different for men and women.

A study conducted at the University of São Paulo provides knowledge for use in diagnosing and treating chronic fatigue syndrome, which affects 10%-20% of patients who recover from COVID-19.

Scientists who analyzed the combined use of two drugs – paclitaxel and immune checkpoint inhibitors – made discoveries that could pave the way for future research to combat the pain caused by other diseases.

As part of a project supported by FAPESP, researchers at a startup called PollinTech are developing a strategy to use to sniffer bees to pollinate coffee crops. The firm took part alongside several other startups in the 22nd PIPE High Tech Entrepreneurship Program hosted by FAPESP to showcase innovative research.

Results of in vitro tests are described by researchers at the University of São Paulo in the journal Scientific Reports point to avenues for the treatment of neurodegenerative diseases.

Grass-covered pasture captures more methane than bare soil, albeit much less than forest-covered soil. Researchers at the University of São Paulo showed that proper pasture management strategies have the potential to reduce the impact of livestock production and mitigate global warming.

An article by researchers at the State University of Campinas in Sport, Education and Society investigates the dark side of Olympic fame. The lead author’s PhD research included interviews with former gymnasts in the Brazilian team.

Researchers at the University of São Paulo detected SARS-CoV-2 on the ocular surface in 18.2% of samples taken from patients hospitalized with the disease. The findings point to an alternative to nasopharyngeal swabbing and highlight the need for health workers to protect themselves from infection by ocular fluids.

Hydrogen peroxide is used to sterilize medical equipment, to bleach fabric, pulp and paper, and whiten teeth, among other applications.

Flexible copper device identifies lead and cadmium in sweat and can be used by untrained personnel to monitor exposure to toxic materials.

A company funded by FAPESP’s program to support innovation by small businesses is launching a dietary supplement for consumer hair care.

In experiments conducted by scientists at the University of São Paulo, the performance of a model obtained in a 3D printer was equivalent to that of the conventional model produced manually. The biomimetic material can be produced on a large scale, reducing animal testing by the cosmetics and pharmaceutical industries.

In Brazil, researchers tracked 80 patients with moderate and severe forms of the disease for up to six months after they left hospital. Muscle impairment during hospitalization was also a predictor of higher healthcare costs in the ensuing months.

A study analyzed changes to the built environment to promote physical activity in Brazil’s largest city between 2015 and 2020, using data from online public libraries as well as the city and state governments.

The school will provide a set of mini-courses delivered by renowned scientists and aimed at early-career researchers working with fields ranging from epidemiology to applied mathematics to political and social sciences. Registrations are due on February 28, 2023.

Researchers at the Federal University of São Paulo and Butantan Institute used several advanced techniques to analyze the venom of the Orange banded tarantula Acanthoscurria juruenicola and tested its capacity to paralyze crickets. The findings could contribute to the development of biodiversity-based solutions.

Deep techs established in São Paulo have flourished in recent years, particularly in 2017-19, according to a survey led by the Brazilian Small Business Support Service.

In an experiment, the survival and physiology of crab larvae on which other species feed were affected by rising sea surface temperatures. Events of this kind will be up to 35% more frequent between now and the end of the century in the study area.

Brazilian researchers have discovered that central nervous system cells from patients with schizophrenia secrete substances that reduce the thickness of blood vessels in the brain, possibly leading to diminished metabolic flux in some parts of the CNS.

Stress, burnout, pain and poor sleep were some of the most frequent symptoms reported by nursing and other staff who care for patients in a study conducted by researchers at the Federal University of São Carlos in São Paulo state, Brazil.
