A groundbreaking study has revealed that not all organs age at the same rate, with significant implications for understanding human aging. Researchers created a "proteomic blueprint of aging," examining how protein markers in various organs change over a 50-year period. The study found that aging accelerates notably after the age of 50, but the aorta, one of the first organs to show pronounced changes, begins aging much earlier, around age 30. This organ acts as a "radio tower," broadcasting proteins like GAS6 that may accelerate aging in other tissues. Professor Guang-Hui Liu, a lead author, emphasized that this research shifts the focus of aging studies from isolated organs to their interactions through blood-borne factors. By identifying organs that age fastest, the findings could pave the way for targeted interventions to slow systemic aging and reduce chronic disease risks. The study is published in the journal Cell. 
Published: Jul 31 2025, 6 pmeznews.inA mystery at the Aquarium and Shark Lab in Hendersonville, North Carolina, has taken a somber turn regarding a stingray named Charlotte, who was initially thought to be pregnant despite the absence of male stingrays. Speculation arose that she could have been impregnated by a shark after two male white spot bamboo sharks were introduced to her tank. However, after extensive testing, the aquarium announced that Charlotte is suffering from a rare reproductive disease that has adversely affected her reproductive system, dispelling earlier theories of parthenogenesis or hybridization. Team ECCO, which operates the aquarium, emphasized their commitment to Charlotte's health and well-being, stating they will collaborate with veterinarians to explore treatment options. The case, while unfortunate, may contribute valuable insights to the understanding of reproductive health in rays, as the aquarium continues to prioritize Charlotte's care.
Published: Aug 31 2025, 11 ameznews.inArchaeologists at Pompeii have revised their initial interpretation of the skeleton dubbed the "unluckiest guy in history," revealing that the man's skull remains intact, indicating he did not die from being crushed by a boulder during the eruption of Mount Vesuvius in 79 CE. The skeleton, discovered in the Vicolo dei Balconi area, belonged to a man under 30 who sought refuge from volcanic debris in a back alley. Researchers believe he was struck by a stone block thrown by the volcanic cloud, which landed on him after a thick layer of ash had already fallen. Initial examinations showed lesions on one leg, suggesting a possible disability that may have hindered his escape. This find adds to the ongoing excavations at Pompeii, which have unveiled numerous artifacts and remains, including a horse preserved in volcanic ash.
Published: Aug 31 2025, 9 ameznews.inGoogle Translate has inadvertently sparked laughter at the expense of flat-Earthers by translating the phrase "I am a flat-earther" into French as "je suis un fou," which means "I’m a crazy person." This amusing translation error, attributed to the platform's statistical machine translation method, has drawn attention from users on Reddit and beyond. Google explained that the translation inaccuracies arise from patterns observed in vast amounts of text online, leading to the mischaracterization of flat-Earthers. The issue extends beyond French, with translations in Romanian, Yoruba, Azerbaijani, and Catalan yielding equally nonsensical results. Despite the ridicule, the flat-Earther movement has seen a resurgence, highlighted by a recent convention in the UK where enthusiasts gathered to share their beliefs. Google has acknowledged the problem and is reportedly working on a fix, but the humorous translations continue to circulate.
Published: Aug 27 2025, 10 ameznews.inSeismologists at UC Berkeley have proposed a model suggesting that Earth's inner core is growing asymmetrically, with one side—beneath Indonesia—developing 60% faster than the other, located under Brazil. This uneven growth may explain the varying speeds of seismic waves traveling through the core, as the iron crystals align preferentially along the planet's rotational axis. Lead author Dr. Daniel Frost noted that this asymmetry is evident throughout the inner core, not just at its surface. The model also refines the estimated age of the inner core to between 500 million and 1.5 billion years, raising questions about the mechanisms that generated Earth's magnetic field prior to the core's crystallization. Professor Barbara Romanowicz emphasized the need for further seismic data to validate these findings, as understanding the Earth's interior remains a complex challenge. The research is detailed in the journal Nature Geoscience.
Published: Aug 31 2025, 7 ameznews.inAn interactive map titled "The True Size Of..." is challenging traditional perceptions of country sizes, revealing the distortions inherent in the widely used Mercator projection. Created by Gerardus Mercator in 1569, this cylindrical map projection is beneficial for navigation but significantly inflates the size of landmasses as they move away from the equator, making Greenland appear as large as Africa, despite being only 1/14th its size. The new tool allows users to drag and compare countries, providing a clearer understanding of their actual sizes relative to one another. It utilizes the Gall-Peters projection, which accurately represents area sizes but sacrifices navigational utility. Users are encouraged to explore the map, particularly comparing their own countries to Greenland, to grasp the true scale of global geography. However, it is advised not to rely on this map for navigation purposes.
Published: Aug 29 2025, 7 ameznews.inA recent study by researchers from Dartmouth College, University College London, and the Institute for Fiscal Studies suggests that the traditional midlife crisis may be fading, not due to improved societal conditions, but because of a significant decline in mental health among younger generations. Historically, the midlife crisis has been characterized by a U-shaped trend in well-being, with a dip in happiness peaking in midlife. However, new data indicates that this "unhappiness hump" has disappeared, replaced by a steady decline in well-being among younger individuals. Analyzing surveys from over 10 million adults in the US and UK, the researchers found that mental health issues are now more pronounced in younger people, with factors such as the Great Recession, inadequate mental health services, and the impact of social media and the COVID-19 pandemic contributing to this shift. The findings highlight an urgent need to address the mental health crisis facing today's youth.
Published: Aug 31 2025, 3 ameznews.inResearchers have rediscovered the sailback houndshark, a species last reported over 50 years ago, during a fisheries survey in Papua New Guinea. Initially collected in 1970 and described in 1973, the shark seemed to vanish until a 2020 survey by the World Wildlife Fund yielded photographs of five deceased females. A male specimen was documented in September 2022, marking the first record of a male. Anecdotal evidence suggests the species may have been caught occasionally by local fishers, indicating it was not entirely lost. However, concerns arise regarding its future, as the sailback houndshark may be confined to the Astrolabe Bay area, which faces increasing fishing pressures, particularly from the trade of fish swim bladders. The study highlights the need for monitoring and management to protect this rare species, which is among several "lost" species rediscovered in recent years.
Published: Aug 30 2025, 2 pmeznews.inThe barreleye fish, a remarkable deep-sea inhabitant, boasts a transparent head that allows its tubular eyes to gaze upwards, akin to peering through a car sunroof, as it hunts for prey in the dark depths of the ocean. This unique adaptation enables the fish to detect silhouettes of potential meals, such as jellies and small crustaceans, while its green eye pigments filter out residual sunlight, enhancing its ability to spot bioluminescent creatures. First described in 1939, the barreleye fish (_Macropinna microstoma_) is primarily found in the North Pacific, though its exact range remains uncertain. A significant breakthrough occurred in 2009 when researchers captured a live specimen, revealing that the fish can rotate its eyes forward to focus on food, challenging previous assumptions about its fixed gaze. This extraordinary adaptation is part of a broader trend in the deep sea, where transparency serves as a camouflage strategy for various species.
Published: Aug 31 2025, 1 ameznews.inLaundry, often seen as a necessary chore in maintaining a polished appearance, can be a labor-intensive task fraught with risks, such as shrinking beloved garments. Nisa Salim, Director of the Swinburne-CSIRO National Testlab for Composite Additive Manufacturing, offers insights into the science behind clothing shrinkage and potential remedies. She explains that cellulose-based fabrics, like cotton, shrink due to "fiber memory," where fibers revert to their original crinkled state when exposed to heat and moisture. Wool, on the other hand, shrinks through a process called felting, where overlapping scales interlock during washing. To unshrink clothes, Salim recommends soaking the item in lukewarm water mixed with hair conditioner or baby shampoo, which helps relax the fibers. By gently stretching the fabric back into shape and drying it flat, wearers can recover some lost size, though complete reversal of shrinkage is not possible.
Published: Aug 28 2025, 7 pmeznews.inHammerhead sharks, known for their distinctive hammer-shaped heads, are remarkable examples of evolutionary adaptation in the ocean's competitive ecosystem. These sharks, part of the Sphyrnidae family, vary in size from the 4-meter great hammerhead to the 1.5-meter bonnethead. Their unique head structure enhances their hunting capabilities by providing a wider field of vision—up to 48 degrees in some species—allowing them to effectively track prey like squid and stingrays. Additionally, the hammer shape aids in electroreception, enabling them to detect electrical signals from hidden prey. While it may increase drag, this head design also enhances their agility, allowing for sharp turns during ambushes. The hammerhead's evolution is a prime example of convergent evolution, showcasing how similar environmental pressures can lead to analogous adaptations across diverse species. Despite their unusual appearance, hammerheads are finely tuned predators, underscoring the diversity of life in our oceans.
