Underprotected Brazilian Wetlands Store Carbon with Staggering Density
Publicado em 16 de março de 2026
The Cerrado savanna occupies about 26% of Brazil and is home to more than 12,000 plant species and diverse animal life. It’s also speckled with groundwater-fed wetlands that serve as the headwaters for two-thirds of Brazil’s major waterways, including the Amazon River, making it not only a biodiversity hot spot but also a critical ecosystem to preserve water security in the region.
This savanna’s wetlands also have another superpower: storing carbon in their waterlogged soils. [...]

Amazonian chocolate: Combining cocoa clones with different post-harvest processes balances flavor and nutritional value
Publicado em 16 março 2026Chocolate produced in the Amazon is internationally recognized for its unique flavor. A study by researchers at São Paulo State University (UNESP) in Brazil has shown that it could be even more valuable. The analysis indicates that postharvest practices such as fermenting the beans from the fruit, combined with the appropriate choice of cultivar, can improve the nutritional quality and flavor of the chocolate, thereby expanding the market... Chocolate produced in the Amazon is [...]ver notícia -
Sleep apnea aggravates muscle loss in people with COPD, research shows
Publicado em 12 março 2026Chronic obstructive pulmonary disease (COPD) is known for causing breathing difficulties and limiting everyday activities. Obstructive sleep apnea syndrome (OSAS), on the other hand, is usually associated with loud snoring and daytime sleepiness. However, a study in the journal Scientific Reports shows that having both conditions has an even more profound impact on patients' muscle strength and quality. "Although it's generally associated only with lung function, chronic obstructive [...]ver notícia -
Wetlands in Brazil's Cerrado are carbon-storage powerhouses
Publicado em 12 março 2026The Amazon rainforest is famous for storing massive amounts of carbon in its trees and soils, helping regulate the global climate. Yet a paper published in New Phytologist shows that one of South America's largest carbon-storing ecosystems exists in an often-overlooked grassy savanna: the Cerrado in Brazil. The study was led by Larissa Verona, a technician working with senior scientist Amy Zanne at Cary Institute of Ecosystem Studies and a former graduate student at Universidade Estadual [...]ver notícia -
6.3-million-year-old glass fragments confirm massive cosmic collision in Brazil
Publicado em 05 março 2026Scientists have officially confirmed the discovery of Geraisites: Brazil’s first-ever field of tektites. These glassy shards are the scorched remains of a massive asteroid impact that rocked the Earth roughly 6.3 million years ago. Named after the state of Minas Gerais, geraisites are dark, aerodynamic glass droplets formed during a massive ancient impact. These rare specimens now span a debris field of over 900 kilometers (559 miles), marking what may be one of the most significant [...]ver notícia -
Natural dye produced by Amazonian fungus can be used in cosmetics
Publicado em 04 março 2026Initial tests with a natural dye produced by the Amazonian fungus Talaromyces amestolkiae show that eco-friendly cosmetics, such as face creams, gel sticks, and shampoos, can be developed with antioxidant and antibacterial properties. This finding is significant because microbial dyes, which are still underexplored in cosmetic research, can serve as a sustainable alternative to synthetic dyes.

Babies exposed to poverty show delays in motor development as early as six months
Publicado em 02 março 2026Poverty can affect babies' motor development as early as six months of age. This is the conclusion of the first Brazilian study to examine the quantity and quality of motor development month by month and its relationship with socioeconomic vulnerability during the first months of life. The study, conducted by researchers at the Federal University of São Carlos (UFSCar) in the state of São Paulo, followed 88 babies from three to eight months of age. Fifty of the babies were from [...]ver notícia -
This Brazilian spider appears to be wearing a pearl necklace but the truth is much creepier
Publicado em 01 março 2026The juvenile spider sat in a glass vials, one of thousands tucked away in the archives of Brazil’s Atlantic Forest collections. To the naked eye, it didn’t look like much. Just another standard specimen. But under the lens, researchers spotted something eerie: a literal necklace of tiny, pearly spheres encircling the spider’s waist. Researchers took a closer look at the necklace. These weren’t decorations. They were vampires. Their discovery, described in the International Journal [...]ver notícia -
Impact-formed glass provides evidence of cosmic collision in Brazil about 6 million years ago
Publicado em 20 fevereiro 2026For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth's surface. These structures, named geraisites in honor of the Brazilian state of Minas Gerais, where they were first discovered, constitute a new strewn field. This expands the incomplete record of impacts in South America. The discovery was described in an article published in the journal Geology by a team [...]ver notícia -
Amazon deforestation raises surface temperature by 3°C during dry season, satellite data show
Publicado em 16 fevereiro 2026Deforestation in the Amazon is causing significant regional changes in climate compared to areas with forest cover above 80%. The loss of vegetation leads to an increase in surface temperature, a decrease in evapotranspiration, and a reduction in precipitation during the dry season and in the number of rainy days. Deforestation in the Amazon is causing significant regional changes in climate compared to areas with forest cover above 80%. The loss of vegetation leads to an increase in surface [...]ver notícia
