Brazil'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 [...]

Approximately 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 [...]

Pollution 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 [...]

In 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 [...]

The 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 [...]

Call 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 [...]
