As deforestation and climate change threaten to transform the Amazon, there is growing concern that the ecosystem may be reaching an irreversible tipping point, beyond which self-reinforcing feedback loops would lock the system in a degraded state and lead to the Amazon flipping from a carbon sink to a carbon emitter. However, anew study, led by Yale School of the Environment scientists, found that there is no evidence of a single, basin-wide tipping point. Instead, there is wide variation [...]

A study by ethnobotanist Hemerson Dantas dos Santos Pataxó Hãhãhãi has revived the ancestral healing knowledge of his Indigenous people. Currently a doctoral student at the Institute of Environmental, Chemical, and Pharmaceutical Sciences at the Federal University of São Paulo (ICAQF-UNIFESP) in Brazil, he belongs to the Pataxó Hã-Hã-Hãi people. According to his doctoral advisor, Eliana Rodrigues, he is the world's first [...]

Researchers at the Optics and Photonics Research Center (CePOF) have succeeded in increasing the susceptibility of the fungus Candida albicans to drug treatment through light-activated therapy. The results of the study offer a promising alternative in the fight against antimicrobial resistance, a growing global problem that occurs when bacteria, viruses, fungi, and other parasites develop genetic mutations that render them resistant to drugs. In the study, published in the [...]

Most trees in the Amazon (90%), the Atlantic Forest (90%), or the Cerrado, the Brazilian savanna-like biome (60%), depend on animals to disperse their seeds, ensure their reproduction, and keep the forest standing. Birds, mammals, fish, and even a species of amphibian play a crucial role in forest diversity around the world. However, this process has been disintegrating as populations of seed-dispersing animals have declined dramatically. The loss of frugivorous animals (whose diet consists [...]

The population of one species of coral in the main island of the Alcatrazes Archipelago Wildlife Refuge (REVIS), located off the southern coast of the state of São Paulo, Brazil, retains about 20 tons of carbon per year. This amount is equivalent to the carbon emissions from burning 324,000 liters of gasoline. These results come from a study published in the journal Marine Environmental Research The authors analyzed specimens of brain coral (Mussismilia hispida), whose skeleton is [...]

Researchers from the Federal University of Alagoas (UFAL) and the State University of Campinas (UNICAMP) in Brazil have found high levels of mercury in the blood and urine of people living on the shores of the Mundaú Lagoon in Maceió, the capital of the Brazilian state of Alagoas. These levels are higher than those found in other populations within the same municipality that have a similar socioeconomic level but live far from the lagoon. The study, which waspublishedin [...]

"Children are the mirror of their parents" is a cliché, but it describes the reality in certain contexts. At least in relation to physical inactivity, this was demonstrated by a study conducted by researchers at São Paulo State University (UNESP) in Brazil. The study examined 182 young people between the ages of 6 and 17 and their respective parents. Using data obtained from accelerometers, which accurately measure levels of activity and inactivity, the researchers [...]

Near the Syrian city of Afrin, an international research team, including researchers from the Senckenberg Center for Human Evolution and Paleoenvironment at the University of Tübingen, has discovered a previously unknown fossil sea turtle. The species Syriemys lelunensis, newly named under the aegis of the University of São Paulo, dates from the early Eocene, about 50 million years ago. The find includes a completely preserved interior impression of the shell as well as parts of [...]

During Brazil's COVID-19 vaccination campaign, when several brands of vaccines were available and the Chinese vaccine was the most common, an unprecedented phenomenon occurred. People crossed neighborhoods or even cities in search of vaccination centers that administered a specific brand of vaccine. Photos of people getting vaccinated were posted on social media alongside proud hashtags praising the national health system, such as "Long live the SUS" (in reference to the [...]
