Scientists are continuing to reap dividends from the US and Russia ’s groundbreaking Twins Study , front at US astronauts Mark and Scott Kelly , with more interesting research from the project announce .
Specifically , thanks to the Twins study scientists think they ’ve found a better means to get biological samples back to Earth from space . They find that samples that had their cells taken out in outer space ( for study and transport to earthly concern ) were good than those where the sampling was frosty , and the prison cell isolation remove place on Earth .
Researchers from NASA came to this ending by handling samples on NASA ’s zero - gravity airplane , known as the Vomit Comet . Here , they used pipettes to move samples around , something that was thought would n’t work in microgravity . But this turn out to be hunky-dory . The inquiry was published in the journalNPJ Microgravity .
“ This analogue present that pipetting of open fluids is relatively simple and easy control and that all fluid transference step associated with centrifugation can be replicated in microgravity , ” research worker Dr Andrew Feinberg said in astatement .
“ When shell out with genic material , research requires the precise transferee of liquids among dissimilar type of tube in ordering to purify DNA , RNA or protein from biologic samples to do molecular analyses . ”
In 2015 and 2016 , NASA do this unique experiment on duplicate astronauts , an chance that could n’t be missed for the potential to study the two at the same time , where one was monitored on the ground and the other on the International Space Station ( ISS ) . Mark Kelly was hit the books on the ground while Scott Kelly spend over 300 day on the ISS .
By supervise both , scientists hoped to see about the transmitted change sustain spaceflight caused . to begin with this twelvemonth , thefirst resultsfrom the study were discharge , which suggested that Scott ’s telomeres uprise longer than his brother ’s . Researchers also saw change in the DNA of the twins .
In the Twins Study , cell were stack away in a vacuum tube at about 4C. In this latest study , that same method acting was used to store and then thaw cells . It was thanks to the Twins Study that this latest breakthrough was possible , and it could intend that we get just sample from biological experiments on the ISS in the future .
