Life at the edge: how microorganisms survive the impossible
In short: What defines the limits of life? This lecture from the German Aerospace Center explores microorganisms that don't just endure extreme conditions—they thrive in them.
Dr. Petra Rettberg examines the laboratory data surrounding extremophiles, organisms that survive in environments once thought to be uninhabitable. These environments are defined by physical and chemical parameters—such as extreme pH, pressure, salinity, and ionizing radiation—that were previously considered to be outside the range of biological viability.
The research highlights a dramatic shift in our understanding of life-limiting conditions. By studying these tough but difficult-to-culture microbes, scientists are redefining the boundaries of biology, discovering life that can withstand and flourish in some of the most hostile conditions on Earth and beyond.
