Story summary

Researchers from the University of Wisconsin–Madison studied bacteriophages and Escherichia coli aboard the International Space Station (ISS).
They found T7 phages can infect Escherichia coli in space, but with an initial delay versus Earth.
Genetic analysis showed distinct mutation patterns, indicating microgravity imposes unique evolutionary pressures.
Space-driven mutations enhanced the phages’ ability to target drug-resistant Escherichia coli strains, suggesting space studies could yield new treatments for antibiotic resistance on Earth.
