A team of geologists has embarked on a quest to identify the oldest rock in the United States, a task that highlights the complexities of determining a rock's age. While Minnesota's Morton Gneiss has long claimed the title, recent assessments suggest it is only 3.5 billion years old, significantly younger than Canada's Acasta Gneiss, which is 4 billion years old. The Morton Gneiss, once touted as the "World's Oldest Rock," has been overshadowed by Michigan's Watersmeet Gneiss, which the researchers now designate as the oldest rock in the U.S. at 3.6 billion years. The study reveals that the age of rocks can be contentious due to geological processes that recycle materials, complicating age definitions. The researchers also suggest that older rocks may lie undiscovered beneath the surface, with Wyoming and neighboring states emerging as potential sites for future exploration. The findings are published in GSA Today. 
Published: Jun 27 2025, 4 ameznews.inIn a recent video released by TIME magazine, former President Donald Trump is seen struggling to handle a bald eagle named Uncle Sam during a photoshoot. The incident occurred in August, when Trump reached for aspirin on his desk, prompting the 27-year-old eagle to lash out. The photoshoot, conceptualized by award-winning photographer Martin Schoeller, aimed to capture Trump's rising popularity as a presidential candidate. However, the footage has raised concerns among critics, particularly given Trump's controversial views on science and climate change, which he has previously claimed is a fabrication by the Chinese. The video highlights not only the challenges of interacting with wildlife but also underscores the ongoing debate surrounding Trump's environmental policies as he campaigns for the presidency.
Published: Jun 27 2025, 11 ameznews.inA recent investigation into the Nuvvuagittuq Greenstone Belt in Canada has bolstered claims that it may contain some of the oldest rocks on Earth, potentially dating back to the Hadean Eon, around 4.16 billion years old. This finding is significant as the Hadean is a crucial period in Earth's history, and the Nuvvuagittuq Belt, located on Hudson Bay's eastern shore, is a leading contender for the title of the planet's oldest rock formation. Researchers from the University of Ottawa, Carleton University, and the French National Research Institute for Sustainable Development conducted isotope measurements that support a Hadean origin, despite challenges in accurately dating ancient rocks. While tiny zircon crystals from Western Australia are known to date back to the Hadean, they are remnants of older rocks, unlike the intact formations in Nuvvuagittuq. The study, published in *Science*, highlights the ongoing quest to understand Earth's early geological history.
Published: Jun 27 2025, 9 ameznews.inIn May 1969, Apollo 10 conducted a successful dress rehearsal for a lunar landing, with astronauts Thomas Stafford, John Young, and Eugene Cernan orbiting the Moon for over 10 hours. During their mission, they reported hearing a mysterious "whistling sound," described by Cernan as resembling "outer-space music." This audio, recorded by onboard cameras, remained undisclosed for nearly 50 years. Following Apollo 10, NASA alerted the Apollo 11 crew, including Michael Collins, about the noise, which he later recounted in his memoir, noting it would have been alarming had he not been forewarned. The sound occurred during the lunar module's separation and ceased upon landing. Collins ultimately learned that the noise was due to radio interference between the lunar and command modules, a fact confirmed by NASA when they released the footage in 2016, dispelling any notions of extraterrestrial origins.
Published: Jun 26 2025, 3 pmeznews.inArchaeologists from the University of Milan have uncovered a Medieval skeleton believed to belong to a young man, aged between 17 and 20, who suffered a gruesome death in the 13th century, likely due to a combination of torture and a botched beheading. The skeleton, found near a cathedral in northern Italy, exhibits symmetrical wounds on the arms and legs, suggesting he was subjected to the notorious "breaking wheel," a brutal torture device used for public executions. This method involved systematically smashing limbs and further inflicting injuries before displaying the victim on a pole. The researchers speculate that the man may have been targeted as a suspected plague spreader, leading to his horrific fate. Additionally, forensic analysis revealed unusual fractures at the base of his skull, likely from a clumsy decapitation. If confirmed, this discovery would mark the first archaeological evidence of wheel torture in medieval northern Italy.
Published: Jun 22 2025, 10 ameznews.inThis weekend marks the peak of the Arietids, the most active daytime meteor shower of the year, offering a unique opportunity for stargazers. While most meteors are not visible during typical daytime hours due to the Sun's brightness, the best time to catch a glimpse is just before dawn on Saturday, June 7. For those who prefer to sleep in, the meteors can still be observed until June 17. To spot the shower, look east towards the constellation Aries, identifiable by its "head" located between the Pleiades and the Great Square of Pegasus. Although the radiant point will be below the horizon, radar data suggests that around 60 meteors per hour may be visible, particularly slow and bright "Earthgrazers" that skim the atmosphere. Stargazers can also use mobile apps for assistance in locating constellations.
Published: Jun 27 2025, 2 ameznews.inOrcas, known for their unique behaviors, are now captivating audiences with their unexpected moonwalking skills. Recent videos show these marine mammals surfacing tail-first and moving backward underwater, a behavior believed to be linked to prey-sharing among family groups, according to marine mammal zoologist Anna Hall. This phenomenon is particularly observed in the transient or Bigg’s killer whales, a population that was officially recognized as a separate species in 2024 after years of speculation. These orcas, which primarily hunt marine mammals like seals and porpoises, are known for their distinct social structures and hunting techniques. One notable individual, T65A Artemis, has gained attention for her moonwalking, often displayed after hunting. The Orca Conservancy noted that this behavior is unique to the Bigg’s killer whales in the Pacific Northwest, highlighting the diverse feeding strategies employed by different orca species across the globe.
Published: Jun 25 2025, 11 pmeznews.inAs extreme temperatures and heatwaves become increasingly common, researchers are exploring innovative methods to cool buildings without relying on air conditioning. A promising new bioplastic film, made from polylactic acid (PLA), can reflect 98.7% of sunlight and passively lower temperatures by up to 9.2°C (16.56°F) in laboratory conditions. This environmentally friendly material allows internal heat to escape into space, keeping buildings cooler than the surrounding air. In practical applications, it has demonstrated an average daytime temperature drop of 4.9°C (8.82°F) and 5.1°C (9.18°F) at night. Simulations suggest that using this film in cities like Lhasa could reduce air conditioning needs by over 20%. Unlike traditional cooling systems, this bioplastic requires no electricity, offering a sustainable alternative to petrochemical-based materials. The findings are detailed in the journal *Cell Reports Physical Science*.
Published: Jun 26 2025, 4 pmeznews.inA fisherman in New South Wales, Australia, recently made a startling discovery when he pulled the severed head of a mako shark from the ocean. Jason, known as Trapman Bermagui, shared the unusual catch on Facebook, prompting a flurry of speculation from online observers. He noted that while he hoped to catch smaller sharks, he instead encountered larger predators that had likely feasted on the mako. Experts suggest that the shark was not decapitated in a single bite but rather nibbled by multiple sharks, leaving just the head attached to Jason's line. Johann Mourier, a shark scientist, explained that even a great white shark would struggle to sever a mako in one go. Mako sharks, known for their speed and agility, can grow up to 3.2 meters and are often referred to as the "cheetahs of the ocean."
Published: Jun 26 2025, 10 pmeznews.inNASA, renowned for its space exploration missions, has also engaged in unconventional research, notably studying the effects of drugs on spider web construction. In 1948, Swiss pharmacologist Peter N. Witt began experiments with various substances, including amphetamines and LSD, observing that while high doses of LSD disrupted web-building, lower doses resulted in intricate, albeit ineffective, webs. In the 1990s, NASA scientists at the Marshall Space Flight Center revisited this research, testing substances like cannabis and caffeine to assess chemical toxicity without harming higher animals. Their findings mirrored Witt's, revealing that caffeine led to particularly chaotic webs. The study employed statistical crystallography to analyze web structures, indicating that increased toxicity correlated with more deformed webs. This research suggests that caffeine, despite its commonality in human life, may exert significant effects on the nervous systems of insects, highlighting the complex interactions between substances and animal behavior.
