Scientists call for biosecurity measures for possible ‘alien invasion’ – Science – Life

An article published in the specialized journal “BioScience” warned of an individual problem that has not been fully considered, at least not in general and published, in the spatio-scientific field:space invasions“.

Although for many this concept is part of the potential arrival of other forms of life on Earth, in fact the investigation document talks about the existence of this problem but ‘The other way’: How far human activity in space will not end up creating new polluting mechanisms far from the planet’s atmosphere.

Bacterial strains with “extreme” resistance to radiation

The article in question was written by Anthony Ricciardi, from McGill University (Canada), jointly with other scientists and specialists. He describes that increased activity outside the planet – currently, space exploration and the establishment of off-orbit tourism are no longer considered – could lead to ‘microbial contamination’. The most important thing to confront is implementation that measures biosafety.

As indicated in a statement, “(They were discovered) Bacterial strains that show extreme resistance to ionizing radiation, drought, and disinfectants. At various NASA facilities from which spaceflights were recruited.

“Given the enormous costs to the resource and human health sectors, biological invasions represent a global biosecurity problem that requires rigorous cross-border solutions,” the document said.

who – which human pollution Reaching beyond Earth’s atmosphere can become a “double-edged sword”. The first warnings about this problem began in mid-2013, when there was talk of microorganisms that could “accompany” space missions and endanger sample return missions.

“Although the risk may seem insignificant, since we haven’t detected extraterrestrial life, not even bacteria, researchers have discovered strains of bacteria completely unknown on Earth in space.‘, denotes ‘DW’.

How do you counter this? Ricciardi and company’s text proposes standardizing the “science of invasion” responsible for the study of causes, effects, and solutions for the introduction of microorganisms outside or inside the planet.

“Research in invasive science has provided new knowledge about epidemiology, rapid evolution, the relationship between biodiversity and community stability, and the dynamics of predator-prey-parasite-host interactions, among many other concepts.” , was put forward.

“The early detection, risk assessment, rapid response and containment protocols currently in use for invasive species on Earth can be adapted to deal with potential extraterrestrial pollutants.‘ confirmed the text.
