eznews.inResearchers at the University of Virginia have identified a key reason why Alzheimer's patients often forget their loved ones, linking this memory loss to changes in the brain's extracellular matrix (ECM). The study, which involved mice, found that the breakdown of "perineuronal nets" (PNNs) surrounding neurons is crucial for stabilizing synapses and forming memories. As these structures deteriorate, patients struggle with social memory, leading to confusion and difficulty in maintaining relationships. The findings suggest that the loss of PNNs occurs independently of amyloid and plaque pathology, presenting a new target for treatment. Promisingly, the researchers have identified existing drug candidates, specifically matrix metalloproteinase (MMP) inhibitors, which have shown potential in preemptively treating memory loss in mice. While this research is still in its early stages, it offers hope for the 55 million people worldwide living with Alzheimer's, as scientists work towards developing effective prevention and treatment strategies.

Participants are asked to categorize various shades, leading to discussions about cultural influences on color interpretation. For instance, the Italian language has distinct terms for shades like turquoise, which can complicate perceptions. This phenomenon is not unique to Italian; many languages, including Japanese and Welsh, use the same word for both blue and green. Research on the Himba people of Namibia reveals that their color categorization differs significantly from Western norms, highlighting how cultural context shapes our understanding of color. Ultimately, the quiz serves as a reminder that individual perspectives can vary widely, prompting reflection on how we perceive reality.
Published: Nov 19 2025, 5 pmeznews.inIn a significant breakthrough, researchers have traced the origins of mummified baboons discovered in Egypt back to the Horn of Africa, specifically around Eritrea, where the ancient port of Adulis likely existed. These baboons, dated to Egypt's Late Period (800–540 BCE), were found at Gabbanat el-Qurud, a site known as the "Valley of the Monkeys." The study, led by Gisela Kopp from the University of Konstanz, utilized advanced genetic analysis of mitochondrial genomes from the mummies, revealing their non-native status and cultural significance in ancient Egypt, where they were associated with the deity Thoth. The findings suggest that the legendary trading port of Punt, long speculated to be the baboons' origin, may actually be synonymous with Adulis, highlighting the complexities of ancient trade networks. While this research sheds light on the baboons' journey, many mysteries of ancient Egypt remain unsolved. The study is published in the journal eLife.

The study, led by Gisela Kopp from the University of Konstanz, utilized advanced genetic analysis of mitochondrial genomes to establish the baboons' origins, which were previously linked to the legendary trading hub of Punt. Kopp suggests that Punt and Adulis may refer to the same location, highlighting the complexities of ancient trade routes and the cultural significance of these primates in ancient Egypt, where they were mummified as offerings to Thoth, the god of wisdom. The findings, published in eLife, illuminate the interplay between biology and history in understanding ancient Egyptian practices.
Published: Nov 19 2025, 3 pmeznews.inResearchers have successfully launched the XL-Calibur telescope from Sweden to Canada, utilizing polar winds to explore high-energy astronomical phenomena, including the Crab Nebula and Cygnus X-1, the first discovered black hole. The six-day flight in July 2024 allowed the telescope to focus on the polarization of X-ray emissions, providing unprecedented insights into the behavior of black holes and their surrounding plasma. XL-Calibur achieved record-breaking technical feats and delivered the most precise measurements of polarization in a black hole X-ray binary to date. Principal investigator Henric Krawczynski emphasized that these observations will enhance computer simulations of black hole physics. The team, which includes collaborators from the U.S. and Japan, plans to conduct another flight in Antarctica in 2027 to further investigate neutron stars and black holes, potentially answering longstanding questions in the field. The findings are detailed in The Astrophysical Journal.
Published: Nov 18 2025, 11 pmeznews.inFor the first time, scientists have confirmed the sighting of a living ginkgo-toothed beaked whale, a species previously known only from a few strandings since its description in 1958. Following years of acoustic monitoring in the North Pacific, researchers embarked on multiple expeditions to identify the source of a unique call, known as BW43. In June 2024, they successfully spotted six beaked whales, with genetic analysis confirming five of them as ginkgo-toothed beaked whales. Among the sightings were a mature male, a young male, an adult female with a calf, and several juveniles. This breakthrough not only identifies the elusive species but also reveals new details about their coloration and suggests they may be more common in the eastern Pacific than previously thought. The findings, published in *Marine Mammal Science*, pave the way for further research into the behavior and distribution of these enigmatic creatures.
Published: Nov 19 2025, 1 pmeznews.inStrawberries, often mistakenly referred to as berries, are actually classified as aggregate fruits from the Rosaceae family, which also includes raspberries and blackberries. The small, seed-like white dots on their surface are not seeds but achenes, each containing a single seed. This unique structure means strawberries do not fit the scientific definition of a berry, which requires multiple seeds and specific anatomical features. Instead, the fleshy part of the strawberry is derived from the swollen receptacle tissue of the flower, while the true fruit, the achenes, remain dry and separate. Interestingly, most strawberry plants propagate through runners, creating clones rather than growing from seeds. This unusual reproductive strategy further distinguishes strawberries from true berries, placing them among other aggregate fruits and drupes in the botanical hierarchy.
Published: Nov 19 2025, 2 pmeznews.inA new study challenges the common belief that the wealthiest individuals, particularly billionaires, are inherently more intelligent or hardworking than the rest of the population. Analyzing data from nearly 60,000 Swedish men, researchers found a strong correlation between intelligence and income up to €60,000 ($64,000) annually, beyond which the link diminished significantly. Notably, those in the top 1 percent of earners scored lower on cognitive tests than their slightly less affluent counterparts, suggesting that extreme financial success may not correlate with higher intelligence. The study highlights that while intelligence can facilitate entry into higher income brackets, it plays a minimal role in achieving ultimate monetary success. However, the research is limited by its focus on a male-only sample, prompting calls for further studies with more diverse populations. The findings, published in the European Sociological Review, urge a reconsideration of who should be viewed as intellectual role models.
Published: Nov 19 2025, 9 ameznews.inThe Byford Dolphin Accident, which occurred on November 5, 1983, in the North Sea, is regarded as one of the most catastrophic diving incidents in history. During a routine operation at a drilling site, a diver mistakenly unlatched a diving bell before it had been depressurized, resulting in a catastrophic decompression event. The diving bell was violently propelled away, killing the diver who had released the clamp almost instantly. Tragically, three other divers in the saturation chambers suffered horrific deaths as their bodies rapidly decompressed, leading to severe internal injuries and hemorrhaging. Autopsy reports detailed the gruesome aftermath, with one diver's remains found in multiple bags, highlighting the extreme violence of the incident. Following the tragedy, the families of the victims campaigned for 26 years, ultimately revealing equipment failures as the cause of the divers' deaths.
Published: Nov 19 2025, 10 ameznews.inBathing habits have varied significantly throughout history and across cultures, from the communal baths of ancient Rome to the avoidance of water in early-modern Europe due to health fears. In contemporary society, regular bathing is often seen as essential. Notably, Amou Haji, dubbed the "world's dirtiest man," lived for over 50 years without bathing, believing that clean water would harm him. His death shortly after his first wash in 2022 sparked speculation about the effects of his long-standing hygiene practices, although he was 94 years old. Other historical figures, like Kailash Singh, who abstained from bathing for 35 years, and Nathaniel Bentley, known as "Dirty Dick," illustrate the extremes of non-washing. Experts warn that neglecting hygiene can lead to skin issues and infections, while excessive washing can also cause skin problems. Ultimately, the frequency of bathing should be tailored to individual needs, balancing cleanliness with skin health.
