The common belief that one dog year equals seven human years has been debunked by recent research led by Trey Ideker, a professor at UC San Diego. This simplistic formula fails to account for the rapid physiological development of dogs, particularly in their early years. Ideker and his team utilized an "epigenetic clock" to study the aging process in dogs, analyzing DNA methylation patterns in 104 dogs, primarily Labrador retrievers, aged from one month to 16 years. Their findings revealed that dogs age quickly in their first few years, slowing down around age seven. Consequently, they developed a new formula for calculating a dog's age in human years: 16 ln(dog age) + 31. For instance, an eight-week-old puppy equates to a nine-month-old human, while a one-year-old dog is comparable to a human in their early 30s. Further research is needed to determine if this formula applies to all breeds. 
Published: Dec 31 2025, 1 ameznews.inA new study reveals that the Amazon rainforest is on the brink of a "hypertropical" climate regime, a condition not seen on Earth for approximately 10 million years, as intense heat and drought push the ecosystem beyond its limits. Researchers predict that by the end of this century, the region could experience prolonged hot droughts for up to 150 days a year, leading to a staggering 55% increase in tree mortality during such events. The study highlights that these conditions, characterized by reduced transpiration and carbon uptake, could significantly disrupt the global climate, as the Amazon plays a crucial role in regulating the planet's carbon budget. Lead author Jeff Chambers emphasizes that while the emergence of this hypertropical climate is concerning, it is not inevitable and can be mitigated through effective climate action. The findings, published in *Nature*, serve as a critical warning for policymakers regarding the future of tropical forests.
Published: Dec 31 2025, 12 ameznews.inA recent social media revelation has left many astonished to learn that paprika, a staple spice in dishes like paella, is not derived from a unique plant but rather from dried sweet and mild peppers. This insight, shared by Australian food company Nutraorganics, has sparked widespread surprise, with users expressing disbelief over their previous misconceptions about the spice's origins. Historically, spicier peppers were introduced to Europe by Spanish explorers, leading to the cultivation of milder varieties that are now commonly used for paprika. While the peppers used for paprika are longer and thinner than typical bell peppers, they belong to the same family. In Hungary, where paprika is a national spice, the sweeter version is predominantly favored. This newfound understanding highlights a surprising gap in culinary knowledge regarding one of the world's most popular spices.
Published: Dec 31 2025, 12 ameznews.inA study examining a pair of identical twins raised in different countries has revealed significant disparities in their cognitive abilities, despite their similar personality traits. Born in Seoul in 1974, the twins were separated at age two when one was lost and later adopted by a family in the US. Unaware of each other's existence until a DNA test in 2018, they were reunited and underwent assessments that showed the US-raised twin had an IQ 16 points lower than her sister in Korea, a finding that challenges previous research suggesting only minor IQ differences among monozygotic twins. While the twins exhibited similar personality profiles, both scoring high on Conscientiousness, their contrasting upbringings—marked by a loving environment for one and a tumultuous childhood for the other—highlight the complex interplay of genetics and environment in shaping human development. The study underscores the need for further research into the effects of cultural and environmental factors on cognitive and personality development.
Published: Dec 27 2025, 2 ameznews.inA new scientific theory suggests that damage to the brainstem may underlie both myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and long COVID, potentially explaining the multi-system effects of these conditions. Researchers from Renegade Research in Denver propose that infections could harm connective tissue in the brainstem, leading to conditions like craniocervical instability and dysregulated intracranial pressure. This damage may disrupt vital functions, impacting the immune and autonomic nervous systems and contributing to chronic inflammation. The study outlines a seven-step pathological process beginning with infection and immune response, which could result in further complications, including reactivation of dormant viruses. Previous brain imaging studies have identified abnormalities in the brainstem of ME/CFS and long COVID patients, supporting this hypothesis. The authors hope their model will inspire new research and treatments for these historically misunderstood conditions, which have long been considered enigmatic.
Published: Dec 30 2025, 11 pmeznews.inPouring used cooking oil down the drain may seem convenient, but it can lead to significant environmental issues, such as the formation of fatbergs in sewers. Instead of this harmful disposal method, experts recommend using oil solidifiers, which transform liquid oil into solid "fat pancakes" that can be safely discarded in the trash. These solidifiers work by emulsifying the oil, allowing it to cool and harden, making it easier to manage. For smaller quantities, these solidified oils can even be composted, while larger amounts may be better suited for recycling into biodiesel, candles, or soap. This innovative approach not only prevents plumbing disasters but also promotes sustainable waste management, turning kitchen waste into valuable resources.
Published: Dec 25 2025, 11 pmeznews.inBlack holes, enigmatic remnants of collapsed stars, continue to perplex physicists, challenging our understanding of fundamental physics. Recent hypotheses suggest that black holes may indicate we live in a holographic universe, where our three-dimensional reality is a projection from a two-dimensional surface. This theory posits that our universe could exist within a black hole of a larger cosmos. The black hole information paradox complicates this further, as Stephen Hawking's work revealed that black holes emit radiation, potentially leading to the irreversible loss of information, contradicting quantum mechanics' principle of unitarity. However, physicist Gerard ’t Hooft proposed that information is encoded on a black hole's surface, akin to a hologram, allowing for its restoration during quantum evaporation. While these ideas are intriguing, they remain speculative, and current physics still provides the best explanations for our universe, urging caution against existential conclusions.
Published: Dec 26 2025, 9 pmeznews.inAs December festivities unfold, one notable celebration is the birthday of Flossie, the world’s oldest living cat, who turns 30 on December 29. Recognized by Guinness World Records in November 2022 at nearly 27 years old, Flossie has defied the odds, as the average domestic cat lives around 14 years. Despite being deaf and partially sighted, Flossie remains active, much to the delight of her owner, Vicki Green, who initially expected her to have only a few months left. Green has shared that Flossie continues to jump around without using the stairs she was provided. While Flossie is currently the oldest living cat, the record for the oldest cat ever belongs to Creme Puff, who lived to 38 years and 3 days, attributed to a lavish diet that included unusual treats like red wine.
Published: Dec 30 2025, 9 pmeznews.inYouTube creators known as the Slow Mo Guys have achieved a groundbreaking feat by filming light at an astonishing 10 trillion frames per second, a speed 20 million times faster than their previous high of half a million frames. This ambitious project, aimed at capturing the fastest phenomenon in the universe—light traveling at 300,000 kilometers per second—was made possible through collaboration with CalTech's Compressed Ultrafast Photography department. The resulting footage showcases light moving the length of a bottle in just 2,000 picoseconds, although the bottle itself was added in post-production. The Slow Mo Guys, who have spent over a decade producing slow-motion videos, expressed excitement about this unprecedented achievement, which allows viewers to witness the speed of light in a way never seen before.
Published: Dec 30 2025, 10 pmeznews.inA recent study has revealed that the occupant of one of the most extravagant Paleolithic burials, known as "Il Principe," may have endured a horrific death after being mauled by a large predator, likely a bear. Discovered in 1942 in Italy's Arene Candide Cave and dated to approximately 27,900 to 27,300 years ago, the teenage boy's grave contained opulent items such as carved antlers and mammoth ivory pendants, initially suggesting high social status. However, the boy's skeletal injuries, including a smashed collarbone and severe skull fractures, indicate a violent encounter with an animal. Remarkably, signs of healing on the bones suggest he survived for two to three days post-attack, likely succumbing to internal injuries. Researchers propose that the lavish burial may have been a ritualistic response to this traumatic event rather than a reflection of the boy's social rank, as similar burials often involve individuals with unusual injuries.
