The mushrooms in 'Super Mario Bros.' are modeled after a real mushroom

‘Super Mario Bros.’ was influenced by ‘Alice in Wonderland’

In 1985’s “Super Mario Bros.,” Mario and Luigi grow larger—becoming “Super Mario Bros.”—if they ingested mushrooms. “...if you think of stories like ‘Alice in Wonderland’ and other types of fairy tales, mushrooms always seem to have a mysterious power, and so we thought the mushroom would be a good symbol for why they get it and get big,” Miyamoto told NPR in 2015.

The levels for 'Super Mario Bros.' were designed by hand

Miyamoto and codesigner Takashi Tezuka sketched the world of the game—called Mushroom Kingdom—by hand before handing it off to developers. In the interview below, they show off some of those original illustrations.

The game turned Mario into a pop culture icon

The 'definitive' history of magic mushrooms

Where did magic mushrooms come from, and how did they get their magical reputation? This article explains the history of the psychedelic fungi from pre-history to now. The earliest concrete evidence of psychedelic mushroom use is 12,000-year-old murals in Northern Australia that portray mushroom iconography. Considering how many species seek out and consume psychoactive substances, such as Siberian reindeer, it's possible human use of these psychedelic mushrooms may predate these murals.

Hit show 'The Last of Us' was based on the real-life Cordyceps fungus

Though it depicted a fictional world with a collapsed society due to a fungal pandemic, this television series (based on an earlier video game) helped raise awareness about fungal threats. It even prompted the US Centers for Disease Control and Prevention to publicly comment on it—clarifying the show’s plausibility. The mind-controlling fungal species in the show is based on a real-life Cordyceps species, a fungus that modifies its host’s behavior before killing it.

A visualization of mycoremediation, where fungi extract toxic and radioactive pollutants from soil

As organisms such as mushrooms grow, they develop large networks of root-like structures called mycelium that spread underground and release enzymes that break down contaminants. By absorbing these chemicals, fungi limit the damage caused by these toxins and localize them within the organism for easier collection and disposal.

‘Donkey Kong’ was based on the ‘Popeye’ franchise

Nintendo pursued the “Popeye” franchise in the early 1980s, hoping that developing an arcade game for the popular character would result in a hit. The bid failed, but Nintendo still used “Popeye” as the model for 1981’s “Donkey Kong.”

MSG was first isolated from seaweed in Japan in 1908

The compound monosodium glutamate has been identified in dairy, meats and vegetables, and provides an "umami"—Japanese for "tasty"—flavor to food. Studies in the late 1960s characterized MSG as harmful, but only when testing doses hundreds of times greater than what would be consumed in a typical diet.

Spiders may manipulate captured male fireflies into mimicking female mating signals
