Over thousands of years, a thin coating of clay, cemented to rocks by manganese and iron, records the history of landscape development and ancient cultures.
In July of 1799, Alexander von Humboldt, the German geographer, arrived in Cumana in northeastern Venezuela. A hundred miles away, at the mouth of the Orinoco River, he found granite boulders that appeared “smooth, black, and as if coated with plumbago." Indian legends explained that these rocks had been burnt by the hot tropical sun, and that they were dangerous to one’s health. While investigating the origin of the rocks, von Humboldt and his crew scoffed at the local legends, but each night they retreated to white beaches, distant from the black boulders.
Von Humboldt's boulders and similar rocks found elsewhere generated a scientific mystery that continued for nearly two centuries. Charles Darwin found dark coated rocks at Bahia in Brazil. Others found such coatings on rocks in the rain forest, underneath glaciers in the Alps and even at the apex of the Pyramid of Cheops. Hypotheses about the origin of the black coating ranged from deposits left by ancient oceans to residues from decomposing organic matter, such as pollen. The most popular hypothesis attributed the coating to a process called sweating. According to the sweating hypothesis, water sweats out of the rocks under the hot sun, and precipitates are deposited as a black coating on the surface when the water evaporates. But was the sun hot enough to induce sweating of solutions from rocks in the rain forest or underneath glaciers?
The black coating has been known by various names, such as wustenlacken (desert varnish) and patina; only recently has the scientific community settled on a term that seems sufficiently broad and descriptive: rock varnish. Even while the origin of the rock varnish remained enigmatic, its physical and chemical structure came to be understood. Rock varnish consists of a thin layer, less titan half a millimeter deep, on a rock‘s surface. The coating is typically composed of about 60 percent clay minerals, 20 to 30 percent oxides of manganese and iron, and trace amounts of more than 30 minor compounds, such as copper and zinc oxides. It is the amount of manganese oxide that determines the color of the varnish. Often, the varnish concentrates manganese oxide to levels up to 100 times that found in surrounding rocks; such high concentrations of manganese oxide make the varnish black. Some varnish lacks manganese altogether and appears bright orange from the abundant iron oxides; this is particularly prevalent on the bottom of rocks and inside rock crevices. In other places, such as the hyperarid Peru Desert, the level of manganese oxide is intermediate, leaving the varnish a brownish orange.
The decisive clue to the mystery of rock varnish was a biological one. In 1981, T. M. Oberlander of the University of California at Berkeley and l suggested that bacteria concentrate manganese in rock varnish. We developed this hypothesis on strong circumstantial evidence. First, manganese-rich varnish often forms where water intermittently flows over rocks. The moisture provides a hospitable environment for microorganisms. Second, varnish develops well on porous surfaces that are easily flushed and, hence, are poor in nutrients. In such a harsh environment manganese-oxidizing mixotrophs (which derive some of their energy from inorganic manganese) are able to live; but faster growing heterotrophic organisms (which rely entirely on organic nutrients) are unable to survive.
A third observation in support of the bacterial hypothesis is that dark varnish grows on rocks with a nearly neutral pH. Nonbiological mechanisms for oxidizing manganese operate only in an alkaline environment, where the pH exceeds 9. Thus, manganese-oxidizing bacteria are one plausible candidate. This line of argument is further supported by findings that varnish is orange when the local pH is too high to support manganese-oxidizing bacteria.
Finally, there are many documented interactions between clay, the primary constituent of varnish, and bacteria. Clay particles are often adsorbed onto the surface of bacteria, and vice versa. Clay concentrates nutrients, a useful property in a nutrient-poor environment, and stimulates bacterial metabolism. And a coating of clay can protect bacteria against desiccation and high temperatures. In combination, these factors supported the possibility that bacteria produce manganese—rich rock varnish.
With these ideas in mind, Oberlander and I examined rock varnish for the presence of bacteria. By searching though varnish with the aid of scanning electron microscopy; we found them—manganese-concentrating bacteria of the genus Metallogenium and other species. Fred Palmer and his colleagues at the University of Washington found bacteria of the genus Arthrobacter in rock varnish. Next, we isolated living bacteria from natural rock varnish; when we grew these bacteria in laboratory cultures, they produced varnish that was morphologically similar to the natural product.

The Osaka Castle, a majestic symbol of Japan's rich history and cultural heritage, has captivated the hearts and minds of countless visitors since its construction in the late 16th century. Originally built by the renowned warlord Toyotomi Hideyoshi, this impressive fortification served as a testament to his power and ambition, as well as a strategic stronghold during the tumultuous Sengoku period. The castle's main tower, or donjon, standing at an impressive 58 meters tall, was a marvel of architectural and engineering prowess, showcasing the ingenuity and skill of the Japanese craftsmen of the time.
However, the Osaka Castle's history is one marked by both triumph and tragedy. In 1615, a mere 32 years after its completion, the castle was besieged and destroyed during the Siege of Osaka, a pivotal battle that marked the end of the Toyotomi clan's rule and the beginning of the Tokugawa shogunate's dominance. The castle lay in ruins for nearly three centuries until it was finally reconstructed in 1931, using a combination of traditional craftsmanship and modern construction techniques.
Today, the Osaka Castle stands as a beloved icon of the city, attracting an estimated 2.5 million visitors annually. The castle's main tower, now a museum, houses an extensive collection of artifacts and exhibits that offer a fascinating glimpse into Japan's feudal past. Visitors can explore the castle's many chambers and passageways, marveling at the intricate woodcarvings, gilded ornaments, and elaborate screen paintings that adorn its interior. The castle's observation deck, located on the eighth floor of the main tower, offers breathtaking panoramic views of the city and the surrounding gardens.
Despite its enduring popularity, the Osaka Castle faces numerous challenges in the 21st century. The increasing number of visitors, combined with the aging infrastructure and the need for regular maintenance, has placed a significant strain on the castle's resources. In response, the Osaka Castle management has implemented a series of measures aimed at preserving the castle's historical integrity while enhancing the visitor experience. These measures include the use of advanced conservation techniques, the implementation of crowd control measures, and the development of interactive exhibits and educational programs.
Furthermore, the Osaka Castle's role as a cultural ambassador has taken on new significance in recent years, as Japan seeks to strengthen its ties with the international community. The castle has hosted numerous high-profile events, including diplomatic receptions, cultural festivals, and academic symposia, showcasing the richness and diversity of Japanese culture to a global audience. As a result, the Osaka Castle has become not only a symbol of Japan's past but also a beacon of its future, representing the nation's commitment to cultural exchange, innovation, and progress.
In conclusion, the Osaka Castle remains a true marvel of Japanese architecture and a testament to the enduring legacy of the nation's feudal past. Its storied history, combined with its ongoing efforts to adapt and evolve in the face of modern challenges, ensures that it will continue to captivate and inspire generations of visitors for years to come. As a microcosm of Japan's rich cultural tapestry, the Osaka Castle embodies the indomitable spirit and resilience of the Japanese people, serving as a powerful reminder of the importance of preserving and celebrating our shared heritage.
