Feb 1, 2024 · Research on the International Space Station studies DNA damage and repair using tools and techniques to sequence, analyze, and even edit DNA. Those tools and techniques have been developed especially for use in space, which has unique safety considerations and where there are limits on the size and weight of equipment.

Jul 23, 2022 · DNA is made up of four base molecules that link together to encode instructions for cell growth and behavior. Identifying the order of the bases using the process of DNA sequencing clues researchers in to the identity of the organisms and how they might behave.

Nov 13, 2024 · Wednesday’s research schedule aboard the International Space Station was packed with DNA-like nanomaterials, ultrasound scans, and a variety of advanced science hardware maintenance. The Expedition 72 crew also continued its ongoing life support and systems servicing ensuring the upkeep of the orbital outpost. NASA Flight Engineers Suni Williams and Nick Hague continued exploring ...

Feb 21, 2019 · In a research breakthrough funded by NASA, scientists have synthesized a molecular system that, like DNA, can store and transmit information. This unprecedented feat suggests there could be an alternative to DNA-based life, as we know it on Earth – a genetic system for life that may be possible on other worlds.

4 days ago · NASA’s OSIRIS-REx mission delivered samples from asteroid Bennu, revealing crucial molecules linked to life, including amino acids and nucleobases found in DNA and RNA. The presence of ammonia and formaldehyde suggests conditions ripe for forming complex molecules in space. Scientists also discov

Nov 21, 2024 · The mystery of why life uses molecules with specific orientations has deepened with a NASA-funded discovery that RNA — a key molecule thought to have potentially held the instructions for life before DNA emerged — can favor making the building blocks of proteins in either the left-hand or the right-hand orientation.

Nov 13, 2024 · NASA Flight Engineers Suni Williams and Nick Hague continued exploring manufacturing DNA-like nanomaterials to develop therapies and treat space-caused and Earthbound conditions on Wednesday.

capability of DNA and RNA sequencing in the microgravity environment of space • Capable of DNA, RNA, and protein sequencing • First launched July 18, 2016 (SpaceX-9) Nanopore-based sequencers measure changes in current caused by DNA strands migrating through the pore. The changes in current are characteristic of the sequence of migrating DNA.

Jun 22, 2018 · DNA sequencing can be used for things in space from monitoring the crew members' health to identifying microbes, and potentially detecting life in the solar system. HWHAP Episode 50. Dr. Sarah Wallace talks about her instrumental role in sequencing DNA for the very first time in space.

Jan 29, 2024 · Synthetic DNA used to diagnose diseases such as COVID, hepatitis, and cancer was developed by Firebird Diagnostics LLC of Alachua, Florida, with research funded in part by the NASA Astrobiology Program.
