Scientists say extraterrestrial object slammed into Brazil 6.3mn years ago, but left no crater. There is another proof
Publicado em 26 de fevereiro de 2026
Scientists have discovered the first field of tektites in Brazil, proving that the country witnessed an ancient impact from an extraterrestrial object. This event happened 6.3 million years ago, as shown by the analysis of the pieces of natural glass found strewn over several kilometres in the northern region. Tektites are formed when a cosmic body slams into the planet with huge force, melting surface rock and throwing it through the atmosphere. They appear black and opaque, but when held to [...]

Scientists stumble upon fastest-spinning asteroid moving at dizzying speed
Publicado em 12 janeiro 2026Asteroid discovery: Scientists have discovered asteroid 2025 MN45 using the Vera C. Rubin Observatory in Chile. This space rock is spinning at an extremely fast pace, making it the first such object discovered in the Asteroid Belt. Asteroid At Record-Breaking Spin The Vera C. Rubin Observatory in Chile, which houses the world’s largest digital camera, has discovered an asteroid that is spinning so fast that it defies any explanation. This record-breaking asteroid, named 2025 MN45, [...]ver notícia -
Asteroid '2025 Mn45' Breaks Speed Records, Cosmic Giant Could Be Nudged Into Earth's Path
Publicado em 09 janeiro 2026Scientists have discovered the fastest-spinning asteroid sized over 0.3 miles in diameter, which is rotating about once every two minutes. Dubbed 2025 MN45, the space rock is some 2,300 feet across and spans nearly the size of eight football fields. The asteroid is of the size of seven football pitches drifting through space. It’s safe for now but scientists warn gravity can change everything. How real is the risk, and can humanity stop a future threat?ver notícia -
Solar storms can trigger heart attacks in women, shocking study finds
Publicado em 30 setembro 2025NASA has warned that the sun is becoming active and can slam Earth with extreme solar storms in the coming weeks. We are aware of the coomunications disruptions geostorms can cause; however, a study has revealed that they can wreak havoc on human health. Researchers from the National Institute for Space Research (INPE) in Brazil have noted a bizarre consequence of solar storms striking the invisible shield around Earth. They revealed that women were at a three times higher risk of heart attacks [...]ver notícia -
Invisible ‘city killer’ asteroids orbiting Venus could hit Earth without warning, scientists warn
Publicado em 28 setembro 2025Astronomers led by Valerio Carruba of São Paulo State University (UNESP) have identified a largely unseen population of asteroids co‑orbiting the Sun in resonance with Venus, objects few have noticed, but which may one day pose serious risk to Earth, his team published findings in Astronomy & Astrophysics. These Venus co‑orbital asteroids, also known as 1:1 mean‑motion resonant objects, share roughly the same orbital period around the Sun as Venus, without being satellites of [...]ver notícia -
Microplastics discovery deep inside human bones sends alarm bells ringing
Publicado em 26 setembro 2025Microplastics continue to be a menace to the environment and human health. Scientists have revealed that they have found traces of microplastics inside the bones as well. A meta-analysis carried out by a group of researchers reviewed currently available data on the impacts of microplastics on human bones. The meta-analysis showed that microplastics "were recently detected in human bone tissue." They have been a cause of concern for years as experts point to the various health hazards [...]ver notícia -
Evil twin? Venus sheltering 'invisible' asteroids that can wipe off humanity with a minuscule change in course
Publicado em 28 maio 2025Venus is hiding several asteroids that can one day prove fatal for Earth. A study has found that several asteroids moving in tandem with our twin planet around the Sun can smash into our planet if something were to move them out of their path. A small gravitational change could be enough to shift them outwards and crash into Earth. Scientists at NASA, the European Space Agency (ESA), Roscosmos, and other space agencies routinely track near-Earth asteroids that can prove potentially hazardous [...]ver notícia -
Ultra-processed food multiplies risk of early death, reveals new study
Publicado em 28 abril 2025Health and Wellness | World: The authors urged governments worldwide to tackle ultra-processed foods with bold measures, like increasing taxes on them and tighter regulations on their sales in schools and workplaces to reduce sales. Consumption of ultra-processed food (UPF) raises the risk of early death many times, reveals new research, rekindling appeals for a clampdown on UPF. The study says that every 10% additional consumption of ultra-processed food, like bread, cakes, and ready [...]ver notícia -
Screaming a defence mechanism? These frogs cry because they cannot physically fight predators
Publicado em 15 abril 2024The crybabies have a permanent place in the Animal Kingdom as full-fledged species. Researchers, for the first time, have identified ear-piercing 'screams' of a tiny amphibian in distress. But their frequency totally bypasses the human ear. But the animals who can hear these frogs scream find it incredibly unpleasant. Interestingly, this crybaby aptitude is a survival skill for the leaf litter frog (Haddadus binotatus). When they are attacked, they do not physically fight back but [...]ver notícia -
Amazon rainforest to reach 'tipping point' by 2050 due to 'stress': Study
Publicado em 15 fevereiro 2024The Amazon rainforest is facing a barrage of pressures that might tip it into large-scale ecosystem collapse as soon as 2050, according to new research Wednesday warning of dire consequences for the region and the world. The Amazon, which holds more than 10 per cent of the world's biodiversity, helps stabilise the global climate by storing the equivalent of around two decades of emissions of planet-warming carbon dioxide. But stress from deforestation, drought, fire and rising [...]ver notícia
