Rare glass from 6-million-year-old meteorite strike found in Brazil — but the crater is still missing
Publicado em 03 de março de 2026
Brazil is host to a newly found field of natural glass created from meteorite impacts, according to a new study.
The natural glass is known as a tektite, which occurs after terrestrial rocks are melted when meteorites, comets, or asteroids slam into the surface of our planet, according to Encyclopedia Britannica. (The word "tektite" is derived from Ancient Greek words that mean "melted" or "molten".)
"Tektites … are known to occur only in five distinct strewn fields on Earth," the [...]

Amazonian fish skin used to develop eco-friendly food packaging
Publicado em 11 fevereiro 2026Researchers at the University of São Paulo (USP) and EMBRAPA Pecuária Sudeste have created a biofilm from tambatinga fish skin, aiming to offer an alternative to conventional synthetic food packaging. A hybrid of female tambaqui and male pirapitinga, tambatinga is known for its rapid growth and high collagen content. Its tropical origin is suggested to contribute to increased amino acid levels in its skin, which may enhance the quality of the extracted gelatin. The project aims to [...]ver notícia -

Something About Brazil's Oldest People May Reveal Missing Clues on Longevity
Publicado em 20 janeiro 2026No one can evade death forever, but some people are mysteriously good at it. While the average human life lasts about seven decades, a few sturdy souls press on to become centenarians – people who live for at least a century. About one in 1,000 centenarians will survive an additional decade, earning the elite title of 'supercentenarian' upon reaching their 110th birthday. Scientists are understandably fascinated by these notable survivors, who may hold valuable secrets about [...]ver notícia -
Scientists make remarkable observation in foreign waters: 'We don't know if there were fewer ... or if they simply disappeared'
Publicado em 09 janeiro 2026A shift in natural behavior by an established predator could help control an invasive fish species found in Brazilian waters. According to an article from FAPESP shared by Phys.org, this shark is often found in Sueste Bay, a sea inlet where fresh water from a nearby mangrove swamp meets salt water in the archipelago of Fernando de Noronha. "This is a breeding, nursery, and feeding area for lemon sharks," said Bianca Rangel, the first author of the study, per FAPESP. "The night before [...]ver notícia -
Newly discovered asteroid spins at record-breaking speed
Publicado em 08 janeiro 2026A crop of asteroids discovered by the new Vera C. Rubin Observatory is wowing astronomers, with one of the space rocks spinning at a record-breaking speed. Among the nearly 2,000 asteroids detected last year by the telescope operated by the National Science Foundation's NOIRLab and SLAC National Accelerator Laboratory, 19 are classified as super-fast or ultra-fast rotators. A new study published in The Astrophysical Journal Letters revealed that one of these objects is the [...]ver notícia -
Vera Rubin Observatory discovers fastest spinning asteroid ever and its huge!
Publicado em 08 janeiro 2026A powerful new telescope in South America is already offering tantalizing hints of what it can do. The Vera C. Rubin Observatory began studying the heavens from a Chilean mountaintop last spring, and its "first light" images wowed astronomers and space fans alike when they were released in June. That initial dataset included observations of nearly 2,000 newly discovered asteroids, and we got some exciting new details about this group on Wednesday (Jan. 7). A new study reveals that 19 of [...]ver notícia -
Scientist issues warning as almost half of beaches set to disappear: 'The result can be the destruction of ... homes'
Publicado em 13 dezembro 2025Beaches around the world are facing a "coastal squeeze" that threatens to eliminate nearly half the planet's sandy coastlines by 2100, says marine scientist Omar Defeo, according to Agência FAPESP. The phenomenon is the result of rising seas, which are driven by heat-trapping pollution combined with coastal development, and it's putting communities at severe risk while also devastating ecosystems. What's happening? Defeo, a professor at Uruguay's University of the [...]ver notícia -
Brazil Approves World's First Single-dose Dengue Vaccine
Publicado em 26 novembro 2025Brazilian authorities on Wednesday approved the world's first single-dose dengue vaccine, which they hailed as a "historic" achievement as cases of the mosquito-borne disease soar globally due to rising temperatures. Dengue, known for intense flu-like symptoms, crushing fatigue and body aches, reached record global levels in 2024 and researchers have attributed its spread to climate change. Brazil's health regulatory agency ANVISA authorized the use of Butantan-DV, [...]ver notícia -
A Simple New Compound Reverses Alzheimer's Symptoms in Rats
Publicado em 21 novembro 2025A new chemical compound has shown promise for treating Alzheimer's disease. Its effects in a rat model of the disease were impressive, and the biochemists who discovered it are eager to progress to in-human trials. A hallmark of Alzheimer's disease is the accumulation of beta-amyloid plaques in the brain. And while it's still unclear whether these plaques cause the disease's symptoms, or are merely a side-effect, they remain a major research focus for treatment. Given [...]ver notícia
