eznews.inRecent research from the University of California, Irvine, has revealed that Botox injections can alter how the brain interprets emotions, supporting the "facial feedback hypothesis." This hypothesis posits that mimicking facial expressions, such as frowning or smiling, helps individuals understand and experience emotions. In a study involving 10 women aged 33 to 40, researchers injected Botox to temporarily paralyze the glabellar muscle, responsible for frowning, and monitored brain activity via fMRI scans before and after the procedure. Findings indicated changes in the amygdala and fusiform gyrus when participants viewed emotional faces, suggesting that Botox disrupts the brain's processing of emotional expressions. Previous studies have also linked Botox to impairments in emotion perception and slower reading of emotional language. Interestingly, while Botox may hinder emotional recognition, it has shown potential benefits for patients with depression, although further research is needed to clarify these effects. The study is published in *Scientific Reports*. 
Published: Oct 20 2025, 4 ameznews.inAstronomers at the W. M. Keck Observatory have made intriguing discoveries regarding interstellar comet 3I/ATLAS, which was first detected on July 1, 2025. This comet, the third interstellar object identified, exhibits an unusual "anti-solar tail," a phenomenon where the tail points towards the Sun, potentially due to large dust grains ejected from its sunlit side. The team also confirmed the presence of nickel and cyanide in the comet's coma, with nickel being more concentrated near the nucleus. This finding raises questions about the comet's composition, as the high temperatures required to vaporize metals like nickel and iron are not present at its observed distances. The study, which has not yet undergone peer review, suggests that 3I/ATLAS may serve as a time capsule from an earlier era of the universe, offering insights into the primordial materials of distant stellar systems.
Published: Oct 17 2025, 12 ameznews.inNew research challenges the validity of the so-called "obesity paradox," which suggests that overweight individuals may have better survival rates after heart failure. A study conducted by the University of Glasgow found that when using waist-to-height ratio instead of body mass index (BMI) to assess body fat, the correlation between higher BMI and improved post-disease outcomes vanished. The study involved over 8,000 patients hospitalized for heart failure and revealed that while higher BMI was initially linked to better survival, this relationship collapsed when adjusted for more accurate measures of body fat and heart failure biomarkers. The findings indicate that BMI is a poor indicator of obesity-related health risks, prompting calls for healthcare professionals to consider alternative metrics. The study, published in the European Heart Journal, underscores the need for more precise measurements in obesity research.
Published: Oct 20 2025, 2 ameznews.inA recent study published in *Frontiers* has revealed that the GLI3 gene, shared by Neanderthals and Denisovans, influences physical traits such as head size and skeletal structure. Researchers utilized CRISPR gene editing to insert this ancient genetic variant into mice, resulting in larger heads, twisted ribs, and shortened spines, which reflect the morphological differences between these extinct hominins and modern humans. While mutations in GLI3 can lead to severe deformities in modern rodents, the ancient version did not cause life-threatening defects but did alter skeletal development. Mice with the archaic gene exhibited fewer vertebrae and rib malformations, suggesting a link to conditions like scoliosis, which recent studies indicate may have affected Neanderthals. The findings imply that the GLI3 gene contributed beneficial traits that aligned with the lifestyles of these ancient species, shedding light on their evolutionary adaptations.
Published: Oct 19 2025, 3 pmeznews.inA record-breaking goldfish, known as The Carrot, was caught in Champagne, France, in 2022, weighing an astonishing 30 kilograms (67 pounds). The carp-koi hybrid, released into BlueWater Lakes two decades ago, has since grown to become one of the largest goldfish in the world. Angler Andy Hackett from Worcestershire, UK, took 25 minutes to reel in the giant before releasing it back into the lake. The Carrot's size highlights the potential for goldfish, typically seen as small pets, to grow significantly when released into the wild, where they can become invasive species. This phenomenon has raised concerns in the U.S., where goldfish can disrupt local ecosystems by outcompeting native species for resources. Experts advise against releasing pet goldfish into natural waterways, emphasizing the importance of responsible pet ownership.
Published: Oct 19 2025, 5 pmeznews.inResearchers have observed a surprising trend where magpies and crows are using anti-bird spikes, designed to deter them, as nesting materials. This behavior, documented in a study published in *Deinsea*, highlights the adaptability of these birds in urban environments. The spikes, while uncomfortable, may provide a protective barrier for eggs against predators, serving a dual purpose similar to their original intent. Notably, magpies have been seen incorporating these spikes into their nests, suggesting a functional use that mirrors human intentions. The study emphasizes the impact of human activity on wildlife, as urban birds increasingly utilize man-made materials for nesting. This phenomenon reflects broader ecological changes in the Anthropocene, where human influence on the environment is profound. Researchers are keen to explore further how these materials affect nesting success and bird behavior, revealing the intricate relationship between urbanization and avian adaptation.
Published: Oct 19 2025, 8 pmeznews.inA recent analysis of search engine data reveals that many people remain unaware of what allspice is made from, prompting a wave of curiosity online. Contrary to popular belief, allspice is not a blend of various spices but is derived from the dried berries of the _Pimenta dioica_ tree, native to Central America. This versatile spice, also known as Jamaica pepper or myrtle pepper, is widely used in cuisines globally, including in traditional dishes from Mexico, the Caribbean, and even Europe, where it is referred to as "ziele angielskie" in Polish. The term "allspice" is believed to have originated from early European colonizers who appreciated its unique flavor profile, reminiscent of cinnamon, nutmeg, and clove. This revelation follows a similar trend where many internet users were recently found to be unaware of the origins of paprika, highlighting a broader gap in culinary knowledge.
Published: Oct 19 2025, 1 pmeznews.inDespite its widespread use in dishes like paella and paprika tea, many people remain unaware of paprika's true origins, as highlighted by a recent social media post from Australian food company Nutraorganics. Contrary to popular belief, paprika is not derived from a unique plant but is made from dried and crushed sweet and mild peppers. This revelation has surprised many, with users expressing disbelief over what they previously thought paprika was. The peppers used for paprika are typically longer and thinner than the bell peppers commonly found in the US. Historically, spicier varieties were introduced to Europe by Spanish explorers, leading to the cultivation of milder versions that are now favored, particularly in Hungary, where paprika is considered a national spice. Ultimately, paprika's identity is rooted in the ordinary pepper, debunking any myths about its exotic origins.
Published: Oct 19 2025, 7 ameznews.inIn a groundbreaking medical achievement, Paul Edmonds, a 67-year-old patient at City of Hope in California, has become the fourth person globally to enter long-term remission from HIV and leukemia. Diagnosed with HIV in 1988 and later with myelodysplastic syndrome, which progressed to acute myeloid leukemia (AML), Edmonds underwent intensive chemotherapy before receiving stem cell transplants from donors with a rare genetic mutation that confers resistance to HIV. Remarkably, he has been free of detectable HIV for over two years after stopping antiretroviral treatment. Edmonds, who aims to inspire others and honor those lost to AIDS, reflects on the significant advancements in HIV treatment since his diagnosis, emphasizing the importance of continued advocacy for better access to care and research into vaccines and cures. His story highlights the potential for hope and recovery for older individuals living with HIV and related health challenges.
Published: Oct 19 2025, 7 ameznews.inIn a significant medical advancement, researchers have successfully replicated a groundbreaking achievement in HIV treatment, initially reported by Johns Hopkins last year. A child born to an HIV-positive mother in Mississippi was declared virus-free after receiving antiretroviral therapy within 30 hours of birth, and she remains healthy without treatment for the past two years. Now, a second baby, born in Los Angeles to a mother with advanced AIDS, has also shown promising results after aggressive treatment commenced just four hours post-delivery, with the virus becoming undetectable within 11 days. While experts caution against labeling these cases as "cured," as ongoing treatment is still necessary, they highlight the potential for future breakthroughs. A clinical trial is set to begin soon, aiming to treat 60 infected infants within their first two days of life, which could provide further insights into effective HIV management in newborns.
