Why Do We Eat Chicken Instead of Other Birds?

Chicken has become a staple in the American diet, with the average person consuming around 45 kilograms (100 pounds) annually, according to the National Chicken Council. The domestication of chickens, believed to have originated in the Indus Valley around 2000 BCE, was facilitated by their docile nature and proximity to humans. Initially bred for cockfighting, chickens eventually became a popular food source, particularly during World War II when red meat was scarce. Unlike other birds, such as pigeons and swans, chickens are easier to farm and more palatable, contributing to their dominance in the poultry market. Genetic studies reveal that domestic chickens are hybrids of the red and grey junglefowl, further highlighting their unique suitability for domestication. Ultimately, the combination of their manageable nature and culinary appeal has solidified chickens' place in global cuisine. sources

Your Body Lotion Isn't Attracting Horny Spiders

A recent product review on Sephora for Sol de Janeiro's Delícia Drench™ Body Butter sparked a humorous yet alarming discussion online, as the reviewer claimed the lotion attracted wolf spiders. The now-deleted review suggested that the body butter made the user irresistible to these arachnids, leading to an unusual spike in sightings. However, experts, including Floyd W. Shockley from the Smithsonian, clarified that wolf spiders typically seek shelter indoors during colder months, not due to the lotion. Sol de Janeiro also refuted the claim, stating their product contains none of the chemicals known to attract spiders. Despite the initial buzz, subsequent reviews have reported no increase in spider encounters, reassuring users that the body butter is safe from arachnid attraction. As the internet continues to debate the issue, it seems the only thing the lotion is drawing is attention from curious customers. sources

Patterns Seen with Closed Eyes: What Are They?

When you close your eyes, you may notice swirling colors and patterns, known as "phosphenes," which are harmless visual sensations created by the eye's internal signals. According to Katrina Schmid, an Associate Professor at Queensland University of Technology, these sensations occur because the cells at the back of the eyes continue to generate weak signals that mimic light, even in darkness. The brain interprets this random activity as visual stimuli, leading to the perception of colors and shapes. While phosphenes are typically benign, they can also indicate potential retinal issues or neurological conditions if they become more pronounced or persistent. Therefore, if you experience significant changes in these visual disturbances, it is advisable to consult a medical professional. sources

Why Sharks Avoid Freshwater Lakes and Rivers

A recent study published in the *Journal of Experimental Biology* explores why sharks rarely inhabit freshwater lakes and rivers, revealing significant physiological challenges. While over 1,000 species of elasmobranchs exist, only about 5% can tolerate freshwater, often part-time. Researchers, including Stanford's Adrian Gleiss, found that sharks, unlike bony fish that possess swim bladders for buoyancy, rely on a lipid-rich liver. In freshwater, sharks experience a two- to three-fold increase in negative buoyancy, necessitating a much larger liver to maintain buoyancy, which is energetically costly. The study also analyzed body density in freshwater elasmobranchs, including bull sharks and largetooth sawfish, revealing they have lower liver densities and the highest negative buoyancies recorded. This research underscores the metabolic and ecological barriers that limit sharks' adaptation to freshwater environments. sources

The 500-Year-Old Bible That Shaped Today's World

A recent study by Professor Nathan MacDonald from the University of Cambridge highlights the profound impact of a 500-year-old Bible map, created by Lucas Cranach the Elder, on modern perceptions of geography and political borders. Printed in 1525, the map was notably flawed, depicting the Mediterranean to the east of Palestine, yet it played a pivotal role in shaping how people understood the Bible and the world. As access to Bibles increased in the 17th century, this map contributed to the notion of political borders as definitive truths rather than symbolic representations. MacDonald argues that the intertwining of biblical narratives and cartography influenced early modern concepts of nationhood, with maps transforming the interpretation of sacred texts. He warns against conflating divine authority with political organization, emphasizing the complexity and evolving nature of both biblical interpretation and political boundaries. The study is published in The Journal of Theological Studies. sources

Yellowstone Wolves Spark Controversy Among Ecologists

Yellowstone National Park, the oldest national park in the U.S., is renowned for its vibrant hot springs and diverse wildlife, including bison and grizzly bears. A significant ecological shift occurred with the reintroduction of wolves in 1995, after a 70-year absence, which has sparked debate among scientists regarding their impact on the ecosystem. Research led by Professor Bill Ripple indicated that the return of wolves initiated a trophic cascade, leading to a remarkable 16-fold increase in willow growth, as elk populations decreased and vegetation flourished. However, a recent rebuttal challenged these findings, citing methodological flaws and inconsistencies in data collection. Ripple's team plans to respond, asserting that their conclusions remain valid despite the criticisms. The ongoing discourse highlights the complexities of ecological restoration and the long-term effects of predator reintroduction in Yellowstone, emphasizing the need for continued research into these dynamic ecosystems. sources

Your Toothbrush: A Beneficial Biodiversity Hotspot

A recent study led by Dr. Erica Hartmann from Northwestern University reveals that bathrooms are surprisingly rich in microbial diversity, particularly in the form of bacteriophages—viruses that infect bacteria. Analyzing 34 toothbrushes and biofilm samples from 96 showerheads, the researchers identified 614 viral operational taxonomic units, with many being previously unrecorded. The findings suggest that while some bacteria on toothbrushes may pose health risks, the phages could help control harmful bacterial strains. Hartmann emphasizes the importance of maintaining a balanced microbial ecosystem, cautioning against excessive use of disinfectants, which can lead to antibiotic resistance. The study highlights the unique microbial communities found in individual bathrooms, with little overlap between samples, underscoring the untapped biodiversity present in our homes. Hartmann encourages a more accepting view of these microbes, noting that most are harmless and play a crucial role in our health. sources

18 Million Tons of "White Gold" Under California's Largest Lake

The Salton Sea, California's largest lake, is emerging as a potential source of lithium, a crucial metal for the green energy transition. A recent report from researchers at Lawrence Berkeley National Laboratory, funded by the Department of Energy, estimates that up to 18 million metric tons of lithium could be extracted from super-hot brine beneath the lake's southern end, although more conservative estimates suggest around 4 million tons. This "white gold" is vital for producing high-performance batteries for electric vehicles and renewable energy storage. However, the Salton Sea is also known for its severe pollution and environmental degradation, having transformed from a tourist destination into a toxic dust bowl due to agricultural runoff and rising salinity. While the lithium extraction presents an opportunity for sustainable energy development, significant challenges remain regarding the environmental impact and the replenishment of lithium stores. sources

Meet Pumuckel: The World's Shortest and Cutest Horse!

Fans of *Parks and Recreation* have a new equine star to adore, as Pumuckel, the world's shortest living horse, captures hearts with his charming personality and glorious mane. Standing at just 52.6 centimeters (20.7 inches) tall, Pumuckel is notably shorter than the average one-year-old human and surpasses the previous record-holder, Bombel, by a few centimeters. His owner, Carola Weidemann, discovered him in 2020 while searching for small therapy horses, describing her shock at his diminutive size. Pumuckel, a Shetland pony, was not bred for his height but is a "quirk of nature." Now a trained therapy horse, he visits nursing homes and schools, bringing joy to those he meets. When not working, Pumuckel enjoys relaxing in the meadow and indulging in treats like hay and carrots at Weidemann's farm in Germany. sources

The Ban on a Small Purple Fruit in the USA

In a surprising revelation for British readers, many Americans have never tasted blackcurrant, a popular berry in the UK known for its rich flavor and high vitamin C content. While blackcurrants (_Ribes nigrum_) are a staple in British cuisine, featuring in products like jams and drinks, their absence in the US stems from a historical ban initiated in the early 1900s. This prohibition was a response to the white pine blister rust fungus, which threatened the timber industry. Although the ban was lifted in some states, including New York in 2003, blackcurrants remain largely unknown to most Americans, with estimates suggesting less than 0.1% have ever tried them. Efforts by advocates like Greg Quinn are slowly introducing blackcurrant products to the US market, but confusion persists, as many still associate the "purple" flavor with grape instead of blackcurrant, highlighting a significant cultural divide. sources
