A team of researchers is employing drones to disperse sterile mosquitoes to combat lethal disease outbreaks such as dengue fever. The team at BirdView, a startup based in São Paulo, Brazil, has been working for years on controlling mosquitoes in crops using aerial methods. But when the team was introduced to the possibility of controlling crop pests and vector-borne diseases like dengue, they got to work. "We immediately saw the impact of potentially using our technology and [...]

Between 10,272 and 23,648 large-scale pre-Columbian structures may still be awaiting discovery in the Amazon. Archaeologists suggest that the vast Amazon basin conceals over 10,000 undiscovered pre-Columbian archaeological sites. According to a recent study, this estimate, derived from advanced remote sensing techniques and predictive spatial modeling, sheds light on the historical impact of ancient societies on the Amazon region. TOPSHOT - A drone view of the Manicore river, deep [...]

Brazilian geologist Fernanda Avelar Santos has recently made a worrisome discovery on an otherwise untouched tropical island in the South Atlantic called Trindade, Phys.org reports. Santos noticed plastic materials in the rocks scattered on the shore. Santos initially came upon the rocks while on a research expedition for her doctoral thesis on geological risks. She found a massive outcropping of blue-green rocks on the island called Turtle Beach, the world's largest breeding place [...]

The Giant Magellan Telescope is the largest telescope ever built, and it is soon finishing construction thanks to the recent $205 million funding that it received from the international consortium that pledged to the cause. It brings a significant space surveillance device that would soon bring images of far-off galaxies and systems, with multiple purposes for the telescope. According to a press release by the Giant Magellan organization, it recently received sizable funding from a [...]

Faraway in a distant star system is a planet with 13 times more mass than the solar system's largest planet, Jupiter. Amazingly, that's not the only reason why astronomers are in awe of what they're calling the "giant Jupiter." This discovery also marks the first time an exoplanet has been found orbiting an evolved binary system in which one of the two host stars is dead. In a study published in the Astronomical Journal, Brazilian astronomers share their analysis of this remarkable find in [...]

A method used by Brazilian scientists was able to calculate the exact amount of radiation that killed a victim during the Hiroshima bombing in 1945. The scientists were under the supervision of Oswaldo Baffa, a professor at the University of São Paulo's Ribeirão Presto School of Philosophy, Science & Letters. Baffa explains that they used the technique called electron spin resonance spectroscopy to perform the dose calculation or what is scientifically known as retrospective [...]
