Scientists discover unknown life forms in ship's mysterious goo

In September, a research vessel on the Great Lakes noticed a mysterious black, tar-like substance oozing from its rudder shaft after returning from a cruise studying algae blooms. This substance, which has been informally named ‘ShipGoo001’, was tested by scientists at the University of Minnesota Duluth’s Large Lakes Observatory, revealing that it was teeming with life forms, including previously undiscovered microorganisms. Doug Ricketts, the marine superintendent and senior research associate, first collected the goo for testing, and the results surprised everyone involved in the study as it thrived in an oxygen-free environment. The researchers, led by Cody Sheik, a microbial ecologist, are particularly curious about the origins of the black goo and are conducting a history of the ship, which was previously a fishing boat purchased nearly three decades ago. There are various scenarios being considered regarding how this mysterious substance ended up in the rudder shaft, with possibilities ranging from it developing in place to hitching a ride on the boat. Due to its sealed environment, the material likely has a complex food web to sustain the life forms within it, raising questions about whether it might also be capable of biocorrosion, potentially damaging the ship's steel structure. Steve Sheik, another researcher on the team, highlights the excitement surrounding the discovery of new species that could be contained in the substance. Additionally, some of the genetic material extracted has been found globally, suggesting that the microorganisms might inhabit a wide variety of environments. The research team remains vigilant for more samples of 'ShipGoo001' to expand their understanding of its microbial diversity and ecological viability. The implications of this discovery are significant, particularly in regards to understanding microbial life in unexpected habitats. If methane-producing organisms are present in this black goo, they could have potential applications in biofuel production. As researchers continue to investigate, they hope that their findings will shed light on other microorganisms living in similar obscure environments, prompting reflections on the diversity of life that may go unnoticed in everyday settings.
