Life beyond Earth could utilize similar informational polymers such as nucleic acids (DNA, RNA). However, the ability to detect non-standard bases or polymers would reduce the risk of false positives during life detection missions. To demonstrate the potential for detection of non-standard bases using nanopore single molecule sequencing, we used…
POPULAR SCIENCE: Charles Q. Choi takes the pulse of Mars scientists on the challenges and benefits of various sites on Mars for future human exploration.
MIT NEWS: Researchers, in a step toward analyzing Mars for signs of life, find that gene-sequencing chip can survive space radiation.
MIT NEWS: We all could be, scientists say — and an MIT-developed instrument might someday provide the proof.
POPULAR SCIENCE: It’s inhospitable above, but signs of life could be lurking beneath the surface.
POPULAR SCIENCE: Someday, microfluidic chips like this one might suss out life on Mars. The chip, developed by SETG, would ride along on a soil-collecting rover and search for microscopic life within Martian dust.
SPACE: “Earth may not be the center of the DNA-based universe,” says Gary Ruvkun.
ASTROBIOLOGY MAGAZINE: The possibility that life was shared between Earth and Mars could be tested with a DNA analyzer. One research team has built a prototype and plans field tests on a South American volcano.
NEW SCIENTIST: NASA has bought into the possibility that life may have once travelled between the two planets and is supporting early development of the sequencing project, called the Search for Extraterrestrial Genomes.
