True Silver: A Story of Skin Coining With Silver in Traditional Asian Medical Practice
No full textSilver, one of the most precious metals on Earth, has captivated humans since prehistoric times for its natural shimmer, which has found its way into coins, jewelry, and ornaments (The Natural Sapphire Company, 2025). In traditional Asian medicine, silver’s significance extends beyond jewelry or currency; it is a key component in a practice called “cạo gió”, which involves releasing energy blockages and restoring balance to the body using a smooth metal tool to scrape the skin. Although it has been passed down through generations as a remedy for various ailments, a question remains: what makes silver the material of choice
Red Flags are my Favorite Color: The Psychology of Falling For the \u27Bad Boys\u27
No full textThe “bad boy” has been a recurring figure in popular culture for years. He’s the leather-jacketed brooding rebel, the dangerous lover, the tortured antihero that we have learned to romanticize. This archetype blends “juvenile masculinities (aggression, rebellion, hypersexuality)” with appealing qualities like “charisma, ruggedness, and sensitivity,” creating a moral ambiguity that captivates audiences (Gopaldas and Molander, 2019). This contradictory mix keeps him popular across movies, songs, and advertisements. But with this archetype being ‘a walking red flag,’ why are we still so bewitched by the bad boy, and should we be
“Time is Our Only Ally!”: Indigenous Heroism and Native Slipstream in Turok, Son of Stone
Full text linkIn this article, I draw on Frederick Luis Aldama’s framework of Graphic Indigeneity to revisit the long history of an Indigenous hero figure in comics: Turok, a pre-Columbian Mandan warrior lost in a prehistoric space known as the Lost Valley. First appearing in Dell’s Four Color Comics #596 (1954), Turok has appeared throughout comics history for nearly 70 years, primarily written and drawn by white creative teams, yet a visually, narratively prominent Indigenous hero in the comics page, one who has periodically been a top-selling popular character in the comics industry. To this end, I argue that Turok is a comic book character imbued with facets of Grace Dillon’s Indigenous Futurism, a heroic figure representing Indigenous ways of being and living through technological innovations and decolonial actions
The Role of Chemistry in the Prevention and Containment of the Zika Virus
Full text linkSimilar to West Nile and yellow fever, Zika is a mosquito-born e dis ease th at has gained quite a bit of attention since its recent arrival in Latin America for its possible link to a string of fetal brain defects. The Zika virus was first identified in Uganda in 1947, but for much of the late 20th century, very little was known about the virus
The Growing Field of Genetic Counseling
Full text linkGenetic counselors aid patients in their decision making, with regards to their genetic predispositions and corresponding risk, by gathering family health history information, informing patients about genetic testing benefits and discussing results and options after test results arrive. Genetic counselors work in a variety of fields including pediatrics, cancer, cardiovascular, neurology, prenatal and preconception
Science and the Supreme Court
Full text linkOn the first Monday of October, the eight justices of the Supreme Court sat on the bench to hear the first oral arguments of the new term, Weyerhauser Company v. United States Fish and Wildlife Services. This case did not involve niche tax laws or contracts, nor did it involve hot button topics like immigration or abortion rights. Rather, it involved the lowly dusky gopher frog
The Genes to Success: Are You Naturally Gifted?
Full text linkHave you ever wondered why it seems that some people struggle in school despite working just as hard as everyone else, yet others can get away with barely studying and still have a 4.0 GPA? Well it turns out there may be some hints in your genome
The Forgotten Heroes of Postman’s Park
Full text linkThe Watts Memorial to Heroic Self-Sacrifice in Postman’s Park contains fifty-three memorial tablets, each dedicated to an act of life-risking bravery, undertaken by an otherwise ordinary individual, largely in the course of their everyday life, and within commonplace surroundings. The memorial’s creator, G. F. Watts, was a pivotal figure in the conception and promotion of the idea of ‘everyday’ heroism in Britain. Where he led, others followed. On this basis, the Watts Memorial has come to inform our understanding of how everyday heroism as a concept was constructed. Further research has now identified eighty-four individuals who were intended for commemoration on the memorial but who are missing. Incorporating these ‘forgotten heroes’ into the memorial radically alters how we understand it. It widens and deepens our understanding of Watts’ construction of everyday heroism and the characteristics that underpinned the Victorian conception of the idea
[Abstract and Associated Excel File for] Quickly Generated Binomial Tree Applications for Options and VaR in Excel without VBA
Full text linkKEY TAKEAWAYS:
Combining Excel’s =LAMBDA and =MAKEARRAY functions allows for the creation of user-defined functions for producing large binomial trees in less than a second.
Further applications of the user-defined functions allow for very quick valuations of European and American style options with large binomial trees. Applying similar techniques allows for the calculation of value-at-risk (VaR) measures.
Because the binomial tree has a certain structure, a ratio can be computed that determines how the portfolio is performing through time relative to the VaR calculation. A high (low) ratio relative to the amount of the time horizon that has elapsed indicates the VaR “worst case” scenario is less (more) likely to be realized. Risk mitigation techniques can then be applied accordingly.
Quickly Generated Binomial Tree Applications for Options and VaR in Excel without VBA
New functionality in Excel allows for the creation of more extensive user-defined functions without VBA programming. Binomial tree applications are generated that can produce large trees in less than a second. Further applications allow for the pricing of European and American style options and value-at-risk (VaR) calculations. Because the binomial tree has a defined structure, a ratio can be calculated to determine if a portfolio is performing well enough through time to avoid the “worst case” scenarios measured by VaR
