They found life in an uncharted lake of the Antarctica Diario de Que su


This week, the global scientific community celebrated great news: a team of 50 professionals – among researchers, mountain workers, military and drills – Americans found life in the deepest and most unexplored lake of the Antarctic. This is Mercer Lake, which despite having temperatures that drop by 0 degrees, the water does not freeze, and is practically isolated from the rest of the world.

The operating cost cost 5.2 million dollars and was led by the US SALSA organization (Scientific Access to the Antarctic subglacial lakes, for its acronym in Spanish). In addition, he had the collaboration and support of the National Science Foundation of the United States.

The expedition was planned for many years, with the expectation of finding unicellular microbes. However, the specialists took a pleasant surprise when discovering that in this precise place there were bacterial cells and remains of crustaceans, plants and fungi, among other species. "It is the dream of a scientist, every day is a party and every meal a banquet," says Clarín, a microbiologist at the University of Montana, who was part of the entourage.

This is an unprecedented finding, as it not only makes it possible to learn more about the Antarctic region and the movement of glaciers, but also It allows you to make approximations about the effects of global warming.

Even, according to John Priscu, no operating scientist: "I could open the door to find out about the essential requirements for life, beyond our world. For example, on the red planet (Mars) or under the ice of the moons of Saturn, which have so different environments. " The next steps will be to study the DNA of the species found.
