A remarkable discovery at the renowned Hell Creek fossil site in North Dakota has revealed a mosasaur tooth, suggesting that these ancient marine predators adapted to freshwater environments without losing their impressive size. The tooth, unearthed by Trissa Ford in 2022, was initially thought to belong to a _Tyrannosaurus rex_ but was identified by marine reptile expert Dr. Nathan Van Vranken as belonging to a mosasaur from the _Prognathodontini_ subfamily. This finding raises intriguing questions about the mosasaur's habitat, as Hell Creek is nearly 2,000 kilometers from the ocean. Dr. Melanie During, part of the research team, posits that these creatures evolved to thrive in river systems, potentially preying on dinosaurs. The study highlights the adaptability of mosasaurs, drawing parallels to modern-day crocodiles, and suggests that the Loch Ness Monster could be more akin to a mosasaur than previously thought. The findings are detailed in a recent publication in BMC Zoology. 
Published: Dec 12 2025, 8 ameznews.inA professor from the Max Planck Institute for Biological Intelligence, Wolfgang Goymann, explores the duality of human nature, likening it to ancient deities that embody both creation and destruction. He argues that while humans possess unparalleled intelligence, this has not shielded us from folly, making us potentially the smartest yet most reckless species. Goymann highlights that intelligence is not exclusive to humans, citing the cognitive abilities of insects like honey bees and crows. He raises concerns about humanity's role in causing a sixth mass extinction, noting that previous extinctions were also instigated by living organisms. Goymann posits that our unique cognitive abilities allow us to knowingly contribute to global destruction, yet he remains optimistic, suggesting that redirecting resources from military spending to environmental solutions could avert catastrophe. His reflections, published in the journal *Ethology*, underscore the urgent need for humanity to leverage its intelligence for the greater good.

This discrepancy often arises because Advent calendar chocolates can contain higher amounts of vegetable oils, sometimes using a cheaper alternative known as compound chocolate, which replaces cocoa butter with less expensive fats like coconut or palm oil. While this allows for easier molding into festive shapes, it can result in a waxier texture and altered flavor compared to traditional chocolate. In the United States, strict regulations mean that products containing vegetable oils cannot be labeled simply as "chocolate," while the European Union has more lenient rules, permitting up to 5% vegetable oil in chocolate products. Consequently, chocolate enthusiasts are advised to check ingredient lists, especially when purchasing cheaper Advent calendars, to understand what they are consuming.
Published: Dec 12 2025, 4 ameznews.inIn a groundbreaking observation off the coast of British Columbia, scientists have documented the first instance of cooperative hunting between killer whales and Pacific white-sided dolphins. Aerial footage captured the two species sharing fish scraps after a successful hunt, prompting researchers to explore their unusual alliance. The study focused on a pod of northern resident killer whales, which were tracked alongside dolphins in 2020. Data revealed 25 interactions where the orcas followed the dolphins, suggesting a mutual benefit during the seasonal migration of Chinook salmon. The dolphins may allow the killer whales to join them due to their ability to tackle larger prey, while the orcas could provide protection against rival pods. Instances of prey-sharing were also recorded, indicating a unique interspecies relationship. The findings, published in *Scientific Reports*, highlight the ecological advantages of this cooperative behavior, although further research is needed to understand its motivations fully.
Published: Dec 12 2025, 4 ameznews.inNASA's Voyager spacecraft, launched in 1977, are on a long journey out of the Solar System and into interstellar space. Voyager 1 is set to reach a significant milestone on November 13, 2026, when it will be one full light-day away from Earth, nearly 50 years after its launch. The spacecraft is expected to cross the Oort Cloud, a theoretical region of icy bodies surrounding the Solar System, which could take centuries to enter and tens of thousands of years to traverse. Currently, Voyager 1 is 164.7 astronomical units from Earth, traveling at approximately 38,027 mph relative to the Sun. While the distance between Earth and the Voyagers fluctuates due to Earth's orbit, Voyager 1 will never again come within a day's light travel from Earth after its 2026 milestone, marking a significant point in its historic journey into the cosmos.
Published: Dec 12 2025, 5 ameznews.inResearchers have identified a new species of tiny toadlet, _Brachycephalus lulai_, in Brazil's Serra do Quiriri region, adding to the 42 known species in this genus, renowned for their diminutive size and vibrant colors. Measuring just 14 millimeters long, the bright orange _B. lulai_ was named in honor of Brazilian President Luiz Inácio Lula da Silva, aiming to promote conservation efforts for the Atlantic Forest and its unique amphibian inhabitants. The species was confirmed through genetic analysis, morphological characteristics, and distinct advertisement calls. Notably, _B. lulai_ exhibits sexual dimorphism, with females being larger than males. Despite its limited range of approximately 8 square kilometers, the species is classified as Least Concern on the IUCN Red List. The findings were published in the journal PLOS One, highlighting the ongoing discovery of biodiversity in this rich ecosystem.
Published: Dec 11 2025, 8 ameznews.inNorovirus, often dubbed the "winter vomiting disease," is making a significant resurgence in several US states, driven by a new, highly contagious variant. Wastewater data indicates a rising trend in norovirus levels, with cases peaking earlier than usual, despite the Centers for Disease Control and Prevention (CDC) reporting that the current season remains within normal limits and fewer outbreaks than last year. The new strain, GII.17, has left many individuals vulnerable due to a lack of immunity from previous infections. Norovirus is highly infectious, requiring as few as ten virus particles to cause illness, leading to symptoms such as nausea, vomiting, and diarrhea within 12 to 48 hours. While most recover within a few days, the virus poses serious risks to vulnerable populations, including the elderly and young children. Good hygiene practices, including thorough handwashing and careful food preparation, are essential to prevent its spread.
Published: Dec 11 2025, 8 pmeznews.inIn a culinary revelation, experts are urging home cooks to stop discarding pasta water, often referred to as "liquid gold." This starchy water, left over after boiling pasta, is rich in properties that enhance sauces, making them smoother and more cohesive. According to food scientist Abbey Thiel, the starch in pasta water acts as a functional ingredient, stabilizing emulsions and helping fats and water blend seamlessly. This results in a glossy, restaurant-quality sauce that clings to pasta rather than sliding off. Recent experiments by Serious Eats' Daniel Gritzer confirmed that pasta cooked with its sauce and a splash of pasta water significantly outperformed other methods. To maximize this kitchen asset, Martha Stewart magazine recommends reserving some pasta water before draining, or even scooping pasta directly into the sauce. Embracing this technique could elevate home-cooked meals, making pasta dishes more flavorful and appealing.
Published: Dec 11 2025, 6 pmeznews.inA recent study suggests that women who engage in sexual activity less than once a week may face a higher risk of early mortality compared to those who have sex more frequently. The research, which analyzed data from 14,542 individuals in the US, found that women with low sexual frequency were 1.7 times more likely to die from any cause by the end of 2015. While no similar correlation was observed in men, both sexes with depression showed improved survival rates linked to more frequent intercourse. The authors noted that sexual activity could enhance cardiovascular health and mitigate age-related functional decline. Although causation cannot be definitively established, previous studies indicate that sexual activity may improve mood and overall well-being. The findings, published in the Journal of Psychosexual Health, suggest that while a weekly sexual encounter may not guarantee longevity, it could contribute positively to health.
Published: Dec 12 2025, 1 ameznews.inA comprehensive study led by Matthew A. Killingsworth, published in the *Proceedings of the National Academy of Sciences*, reinforces the notion that increased income correlates with greater happiness. Building on a 2018 study that suggested happiness levels plateau at around $60,000 to $75,000, Killingsworth employed a refined methodology to gather data from 33,391 working-age adults in the U.S. Using the Track Your Happiness app, participants reported their feelings in real-time, revealing a linear relationship between income and both momentary well-being and overall life satisfaction. The findings indicate that higher incomes consistently lead to improved emotional states, with no discernible threshold where this effect diminishes. Killingsworth posits that greater disposable income allows individuals to alleviate suffering and enhance enjoyment, suggesting that the point at which money ceases to boost well-being may be higher than previously believed.
