Global rise of ultra-processed foods threatens public health: Study
Publicado em 20 de novembro de 2025
The rapid worldwide rise in ultra-processed foods (UPFs) is fueling chronic disease and requires urgent, coordinated government action, warns a new study.
The three-paper series published in the British medical journal The Lancet, produced by 43 international experts, concludes that UPFs are displacing fresh and minimally processed foods across the globe, worsening diet quality and increasing the risk of conditions including obesity, type 2 diabetes, cardiovascular disease, depression and [...]

Climate change drives record wildfire CO2 emissions, study warns
Publicado em 14 agosto 2024Wildfires made more frequent and intense by climate change released significant quantities of carbon dioxide into the air in 2023-2024, according to a first-of-its-kind annual study published. Fires in natural areas caused 8.6 billion tonnes of carbon dioxide emissions worldwide between March 2023 and February 2024 – 16% above average. Only a relatively calm fire season in the African savannah prevented the 2023-2024 season from breaking a fresh record for carbon dioxide emissions [...]ver notícia -
Amazon degradation emits more carbon than deforestation: Study
Publicado em 06 agosto 2024Brazil's President Luiz Inacio Lula da Silva came into office in 2023, pledging to tackle deforestation in the Amazon and restore his country as a climate leader after years of intense destruction in the world's largest rainforest under his predecessor, Jair Bolsonaro. Lula's commitment to end deforestation by 2030 is on track with tighter enforcement helping to cut deforestation rates by more than half, according to government figures. But a new study indicates that [...]ver notícia -
Study: Nearly half of Amazon forests at risk of extinction by 2050
Publicado em 16 fevereiro 2024Approximately half of the Amazon forest system is in danger of extinction by 2050 due to high exposure to "unprecedented stress from warming temperatures, extreme droughts, deforestation and fires,” according to a new study. Scientists issued the warning in a study published Wednesday in Nature magazine. Noting that 38% of the Amazon is being degraded, the researchers said, "We estimate that by 2050, 10% to 47% of Amazonian forests will be exposed to compounding [...]ver notícia -
New pollution height: Researchers find 'terrifying' plastic rocks
Publicado emPollution of the Earth has reached a new milestone as it now affects its geology, scientists have revealed after the discovery of rocks made from plastic debris in the remote turtle refuge of Brazil's volcanic Trindade Island sparked new alarm. Melted plastic has become intertwined with rocks on the island, located 1,140 kilometers (708 miles) from the southeastern state of Espirito Santo, which researchers say is evidence of humans' growing influence over the earth's geological [...]ver notícia -
COVID-19 roundup: Antiviral drug, genes and cell function
Publicado em 03 outubro 2021In this week's roundup, the latest scientific research on the coronavirus and efforts to find treatments and vaccines suggest that antiviral drug remdesivir helped keep high-risk COVID-19 patients out of hospital and that when the coronavirus infects cells, it not only impairs their activity but can also change their function. A protein called CD47 that helps damaged cells avoid destruction by the immune system may be contributing to severe cases of COVID-19, researchers believe. Drugs in [...]ver notícia -
Brazil's Amazon capital Manaus may have achieved herd immunity to COVID-19, study suggests
Publicado em 24 setembro 2020The Brazilian city of Manaus, which was devastated by the coronavirus pandemic, may have suffered so many infections that its population now benefits from "herd immunity," according to a preliminary study. Published on the website medRxiv, the study analyzed infection data with mathematical modeling to estimate that 66% of the population had antibodies to the new coronavirus in Manaus, where the pandemic's passage was as fast as it was brutal. That may be sufficiently high to [...]ver notícia -
New species of electric eels discovered in the Amazon, including one that can deliver a 860V jolt
Publicado em 12 setembro 2019Call it a shock discovery: DNA research has revealed two entirely new species of electric eel in the Amazon basin, including one capable of delivering a record-breaking jolt. The findings are evidence, researchers say, of the incredible diversity in the Amazon rainforest — much of it still unknown to science — and illustrate why it is so important to protect a habitat at risk from deforestation, logging and fires. "In spite of all human impact on the Amazon rainforest in the [...]ver notícia
