Turns out those ancient fossils from Brazil (once thought to be signs of early animals) are actually leftovers from microbes like bacteria and algae. Using high-tech imaging, scientists spotted preserved cell structures that matched shallow-ocean microorganisms from 540 million years ago, flipping what we thought about early life. Nanoscale accelerator imaging challenges animal origins This discovery shakes up theories about when animals first appeared and what Earth's earliest [...]

Construction workers breaking ground on a road-rail terminal in Davinópolis, Maranhão, in northeastern Brazil, did not expect to make history. Nearly 26 feet underground, they hit something that hadn't seen the light of day in 120 million years: the fossilized bones of a dinosaur so large that researchers are still wrapping their heads around it. Now known as Dasosaurus tocantinensis, the creature is shaping up to be one of the most significant dinosaur discoveries in recent memory, [...]

Imagine digging out the foundations of a brand new structure and accidentally hitting something that's never been exposed to sunlight in the past 120 million years. The bustling city of Davinopolis, situated within the Brazilian state of Maranhao, which began as regular environmental monitoring as part of an upcoming construction project, became one of the biggest discoveries of palaeontology of South American history. In the shadows of eight meters beneath the surface are the skeletons of [...]

Researchers conducting an extensive study of ancient microfossils in Mato Grosso do Sul, Brazil, have challenged long-held beliefs regarding early animal life on Earth. Their findings, published in Gondwana Research , reveal that structures previously thought to be traces from tiny marine animals were instead formed by communities of microscopic bacteria and algae. This groundbreaking research calls into question the timeline of the emergence of animals, indicating that oxygen levels in the [...]

SAO PAULO(AP) — The administration of Brazilian President Luiz Inácio Lula da Silva frequently touts how it has sharply slowed deforestation in the Amazon, and indeed it has. When the next official annual numbers are released in October, the deforestation rate is expected to be the lowest since 2012. Despite gains in keeping forest standing, however, many other threats, ranging from climate change to potential legislation on the horizon, are putting the forest at risk. Forest [...]

'Popcorn effect' against viruses? Researchers find ultrasound can destroy COVID-19, flu Scientists in Brazil have discovered a new way to attack viruses like COVID-19 and influenza — using high-frequency ultrasound waves that can rupture viral particles without damaging surrounding human cells. The breakthrough could pave the way for a new generation of non-invasive antiviral treatments. The research, published in the journal Scientific Reports, found that ultrasound frequencies [...]

Scientists in Brazil have discovered a new way to attack viruses like COVID-19 and influenza — using high-frequency ultrasound waves that can rupture viral particles without damaging surrounding human cells. The breakthrough could pave the way for a new generation of non-invasive antiviral treatments. The research, published in the journal Scientific Reports, found that ultrasound frequencies between 3 and 20 MHz can destabilise enveloped viruses such as SARS-CoV-2 and H1N1 influenza [...]

Researchers at the University of São Paulo (USP) in Brazil have discovered that high-frequency ultrasound waves similar to those used in medical exams can eliminate viruses such as SARS-CoV-2 and H1N1 without damaging human cells. In an article published in Scientific Reports, they describe how the phenomenon, known as acoustic resonance, causes structural changes in viral particles until they rupture and become inactivated. “It’s kind of like fighting the virus with a shout. In this [...]

SAO PAULO (AP) — The Brazilian government, under President Luiz Inácio Lula da Silva, has reported significant progress in reducing deforestation rates in the Amazon, with projections indicating the lowest levels since 2012 when the annual statistics are published in October. However, various challenges, including climate change and impending legislation, threaten the forest's stability. Forest degradation, primarily caused by wildfires, logging, and drought, now impacts approximately [...]
