Bidets have been considered taboo throughout US history

Americans only became intolerant of body odor in the last century

Daily bathing only became a societal norm in the last century. Today, Americans routinely bathe and buy more deodorant than any other country, spending roughly $6 billion annually on odor-reducing products. The rise of industrialized soaps, deodorants, and antiperspirants—and extensive marketing around them—stimulated this demand.

Western babies often are missing a key gut microbe common elsewhere

France once had a reproduction czar to help midwives deliver babies

Some countries have resorted to drastic measures to restore the tarnished state of these hallowed institutions.

Q-tips, invented in the 1920s, were first called 'Baby Gays'

After an immigrant from Poland observed his wife's method of wrapping a wad of cotton around a toothpick to clean their newborn daughter Betty's eyes, ears, and elsewhere during bathing he marketed the product in the mid-1920s as "Baby Gays." The later "Q-tip" name has competing origin stories—with the "q" standing for "quality" or, alternatively, it's a play on "Cutie-Tips" reportedly because Betty was a cute baby.

IVF was long considered controversial and ethically dubious

The symbol of the American lawn

Trimmed, pure green lawns are the norm in US yards and require regular mowing, fertilizing, and weed whacking to keep in order. They are cherished for their simple aesthetic and as a soft area for walking or playing near the house. Still, they are also so-called monoculture zones with only one plant species, lacking biodiverse resilience. This article traces the history of the lawn in America and the contemporary debates over its future.

Understanding how the commodification of water has contributed to global water scarcity

In 2010, the UN General Assembly recognized access to water and sanitation as a basic human right, noting that an estimated 884 million people worldwide lack access to safe drinking water.

Tokyo's transparent toilets use smart, automatic glass to make cleanliness visible

Dubbed the Tokyo Toilet project, this initiative installs restrooms whose walls are transparent when empty, so users can see whether they are clean and safe. When they lock, they turn opaque for privacy. Beyond addressing two key anxieties (hygiene and security), the project lends a distinct architectural prestige to typically banal (and reviled) toilets.
