Genomics Research In Orbit

Flight Engineer Christina Koch of NASA works on the Genes In Space-6 (GIS-6) experiment inside Europe's Columbus laboratory module.

First DNA Sequencing Conducted in Space

For the first time ever, DNA was successfully sequenced in microgravity as part of the Biomolecule Sequencer experiment performed by NASA astronaut Kate Rubins this weekend aboard the International Space Station.

NASA's Human Research Program (HRP) is releasing the video "Omics: Advancing Personalized Medicine from Space to Earth", to highlight its Twins Study, coinciding with National Twins Days.

Biologists around the world routinely perform gene expression analysis to better understand living systems.

Sequencing DNA in Space

NASA is not often known for making the best use of existing COTS (commercial off the shelf technology) aboard the ISS. Then again, sometimes they are. This is an example of when the agency really grabs cutting edge biotech and sends it into space.

"It's a project 500 million years in the making. Only this time, instead of playing on a movie screen in Jurassic Park, it's happening in a lab at the Georgia Institute of Technology. Using a process called paleo-experimental evolution, Georgia Tech researchers have resurrected a 500-million-year-old gene from bacteria and inserted it into modern-day Escherichia coli (E. coli) bacteria. This bacterium has now been growing for more than 1,000 generations, giving the scientists a front row seat to observe evolution in action. "This is as close as we can get to rewinding and replaying the molecular tape of life," said scientist Betuel Kacar, a NASA astrobiology postdoctoral fellow in Georgia Tech's NASA Center for Ribosomal Origins and Evolution. "The ability to observe an ancient gene in a modern organism as it evolves within a modern cell allows us to see whether the evolutionary trajectory once taken will repeat itself or whether a life will adapt following a different path."
