In a groundbreaking study, researchers have demonstrated that a 10-week regimen of brain exercises using the app BrainHQ can significantly enhance the production of acetylcholine, a crucial neurotransmitter, in cognitively healthy adults aged 65 and over. Led by Dr. Etienne de Villers-Sidani from McGill University, the study revealed that participants engaging with the app experienced improvements in their cholinergic system, effectively restoring levels typically seen in individuals a decade younger. This marks the first successful intervention to boost acetylcholine production in humans, surpassing previous drug-based treatments that only inhibited its breakdown. The findings, published in JMIR Serious Games, suggest that such brain training could serve as a low-risk alternative or complement to medication, potentially reducing healthcare costs significantly. The team plans to further investigate the app's effects on individuals showing early signs of dementia, highlighting the importance of brain exercises for overall health. 
Published: Oct 15 2025, 8 pmeznews.inThe "Chicago rat hole," a sidewalk imprint that gained viral fame after being shared on social media, has been the subject of scientific inquiry. Initially thought to be the mark of a rat, researchers have determined that the imprint likely belongs to a large-bodied rodent, with Eastern grey squirrels being the most probable candidate. A study published in *Biology Letters* suggests that the unfortunate animal did not survive its fall, as there is no evidence it walked away after the incident. The researchers propose renaming the imprint the "Windy City Sidewalk Squirrel" and highlight the commonality of falls among urban squirrels. The study emphasizes the importance of curiosity and observation in scientific inquiry, accessible to anyone interested in the natural world. The original imprint, which has attracted visitors and even wedding ceremonies, was removed in April 2024 and is now displayed at the City Hall-County Building.
Published: Oct 15 2025, 11 pmeznews.inEnglish physicist Brian Cox has shared his insights on comet 3I/ATLAS, an interstellar object discovered by astronomers at the Asteroid Terrestrial-impact Last Alert System (ATLAS) on July 1, 2025. Notably, 3I/ATLAS is the fastest object of its kind ever observed, with an eccentricity of 6.1 to 6.2, indicating its interstellar origin. Confirmed as a comet due to its outgassing, it has sparked speculation about its nature, prompting responses from SETI and NASA, although scientists largely regard it as a natural object. Cox highlighted the significance of capturing images of 3I/ATLAS from Mars using the European Space Agency's ExoMars Trace Gas Orbiter, noting its potential formation over 7.5 billion years ago, predating the Earth and Sun. He emphasized humanity's remarkable progress in space exploration, contrasting it with historical debates about our place in the cosmos.
Published: Oct 15 2025, 9 pmeznews.inWednesday, May 30, marks World Otter Day, a celebration often filled with adorable images of otters engaging in playful antics. However, beneath their charming exterior lies a darker reality, as otters exhibit aggressive and violent behaviors. Sea otters, for instance, are known for their brutal mating practices, where males can drown females and even attack pups. Disturbingly, they have also been documented engaging in forced copulation with baby harbor seals, leading to severe injuries or death. Additionally, instances of necrophilia have been observed, with males copulating with deceased females. The giant otter of South America, a formidable predator, further exemplifies the species' ferocity, hunting in packs and consuming a carnivorous diet. While violent encounters with humans are rare, otters can transmit diseases like Valley Fever, posing a hidden threat. As World Otter Day approaches, it’s essential to recognize the complex and often troubling nature of these creatures.
Published: Oct 15 2025, 7 pmeznews.inScientists are exploring the concept of a "sixth sense," with interoception—a sense of the body's internal state—emerging as a leading candidate. Researchers at Scripps Research and the Allen Institute have been awarded a $14.2 million grant from the National Institutes of Health (NIH) to investigate this complex sensory system, which monitors physiological signals related to hunger, pain, and other bodily functions. Led by Nobel Prize-winning neuroscientist Ardem Patapoutian, the team aims to create the first comprehensive atlas of interoception, mapping how sensory neurons connect to internal organs. This research is crucial, as dysregulation of interoception is linked to various health issues, including autoimmune disorders and chronic pain. By better understanding body-brain communication, the researchers hope to develop new treatment approaches and shed light on how the brain maintains bodily balance, a largely unexplored area in neuroscience.
Published: Oct 15 2025, 6 pmeznews.inA recent exploration into Earth's geography reveals a striking imbalance in the distribution of landmasses, primarily concentrated on one side of the planet. While maps suggest a more even spread, a closer look at a globe shows that the vast Pacific Ocean dominates the opposite side, leaving continents like Africa, Europe, and Asia clustered together. This phenomenon can be traced back to the ancient supercontinent Pangea, which existed from 336 to 175 million years ago. The ongoing process of continental drift continues to shape our planet, with the Atlantic Ocean widening and pushing the Americas away from Europe and Africa. Over the next several million years, continents will gradually shift, potentially leading to the formation of a new supercontinent. For now, the Pacific remains a colossal expanse, illustrating Earth's dynamic geological history and the forces that continue to mold its surface.
Published: Oct 10 2025, 10 pmeznews.inA newborn Spix’s macaw hatchling at Pairi Daiza zoo in Belgium is igniting hope for the species, which was declared extinct in the wild around 2018, following the last sighting in 2000. The Spix’s macaw, known for its vibrant blue plumage and inspiration for the animated film *Rio*, has been the focus of international breeding programs, with the recent hatching marking a significant milestone after 100 previous eggs failed to fertilize. Bird keepers attribute this success to a dietary change, and the chick is currently being hand-fed every two hours by specialists. Although it will not be reintroduced into the wild, the hatchling is expected to contribute to breeding efforts aimed at creating a genetically diverse population. Despite a previous reintroduction program in Brazil being halted, there remains cautious optimism that this new addition could help stabilize the future of the critically endangered species.
Published: Oct 14 2025, 9 pmeznews.inThe _Decaisnea fargesii_ shrub, often overlooked for its ordinary leaves and flowers, surprises observers in autumn with its peculiar fruit, nicknamed "dead men’s fingers." These gray-blue, chunky pods, resembling fingers with creases and pointed tips, were first documented in 1892 by French botanist Adrien René Franchet, who initially likened them to large blue caterpillars. The plant, named after missionary Paul Guillaume Farges, thrives in the temperate climates of Sichuan, Tibet, and Nepal, ripening just in time for Halloween. While the fruit, also known as blue sausage fruit, contains edible pulp surrounding black seeds, its taste is described as bland, akin to jelly, though some, like seed morphologist Wolfgang Stuppy, find it pleasantly sweet with hints of melon. Despite its eerie appearance, the fruit invites curiosity about its flavor, leaving many to ponder whether they would dare to taste "dead men’s fingers."

Published: Oct 15 2025, 12 pmeznews.inDuring a recent expedition by the E/V Nautilus in the uncharted deep-sea regions of the Cook Islands, researchers encountered a peculiar species of cusk eel, _Typhlonus nasus_, which resembles a giant, faceless tadpole. This bizarre creature, spotted swimming at depths of up to 5,100 meters, has drastically reduced facial features, leading to its eerie appearance. Despite its lack of visible eyes, juveniles possess tiny eyes hidden beneath the skin, an adaptation to the dark abyssal zone where sunlight does not penetrate. The Nautilus team expressed their excitement over the sighting, as these elusive fish are rarely observed, with the last significant sighting in Australian waters occurring in 2017 after a long absence since 1873. The expedition, which runs until October 21, aims to uncover more of the ocean's strange inhabitants, promising further discoveries in the deep sea.
