Scientific experiments
The cave has been used to conduct experiments in
chronobiology. Among the cavers that have spent considerable amount of time inside the cave is the Italian sociologist
Maurizio Montalbini. In 1986, he ventured into the Grotte di Frasassi beneath Italy's Apennine mountains. He survived on pills, powders, and other astronaut-like food while researchers monitored his health. His few luxuries were chocolate, honey, and plenty of tobacco, smoking nearly two packs of cigarettes a day. During his time underground, away from sunlight, Mr. Montalbini lost almost 30 pounds. He would stay awake for 50 hours at a stretch, then sleep for five. He spent his time reading and writing a novel titled "Where the Sun Sleeps." He reported enjoying his underground experience, aside from the occasional earthquakes."One cannot fight solitude, one must make a friend of it," he remarked after emerging 210 days later, although he believed it had only been 79 days. He died in 2009.
Penn State Research
Penn State researchers, led by Professor Jennifer Macalady, a microbiologist, studies microbial biofilms in some of the planet's most hostile environments to understand the limits of life and how life started on Earth. Macalady, along with doctoral student Dani Buchheister, explored Italy's Frasassi cave system, sampling biofilms, referred to as "alien cave goo" due to its stringy dark nature, from underground lakes, including Lago Verde. Their research, featured in the December 2023 issue of National Geographic, sought to uncover how microbes survive in extreme conditions without sunlight or oxygen, akin to early Earth. Key findings included that microbes can survive with minimal resources such as rocks and water, and that these biofilms may reflect the first metabolic processes on Earth.
