Sterling EricssonThe project in synthetic biology of developing cells from scratch with the most minimal systems possible continues, now with the ability to make movement happen.Max Planck Institute scientists have taken artificial liposome vesicles made in previous experiments and combined them with Min proteins from E. coli, surprisingly creating a mechanical force gradient and moving the vesicles.<a href="https://mstdn.science/tags/Motility" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Motility</a> <a href="https://mstdn.science/tags/SyntheticBiology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SyntheticBiology</a> <a href="https://mstdn.science/tags/Biology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Biology</a> <a href="https://mstdn.science/tags/Biotechmistry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Biotechmistry</a> <a href="https://mstdn.science/tags/Proteins" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Proteins</a> <a href="https://mstdn.science/tags/Science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Science</a> <a href="https://mstdn.science/tags/Scicomm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Scicomm</a><a href="https://www.nature.com/articles/s41567-023-02058-8" rel="nofollow noopener noreferrer" target="_blank">https://www.nature.com/articles/s41567-023-02058-8</a>

Sterling EricssonWhile we know quite a lot on how evolution developed through the history of life, some parts continue to be a source of study. How early cells changed into swimming motile forms is one of those areas. Osaka City University scientists have taken Spiroplasma motility genes and inserted them into the synthetic minimal genome bacteria syn3, causing it to change from a sphere to a spiral helical swimming shape.<a href="https://mstdn.science/tags/Biotech" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Biotech</a> <a href="https://mstdn.science/tags/Biotechnology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Biotechnology</a> <a href="https://mstdn.science/tags/Motility" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Motility</a> <a href="https://mstdn.science/tags/sciencemastodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sciencemastodon</a> <a href="https://mstdn.science/tags/scicomm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#scicomm</a> <a href="https://www.science.org/doi/10.1126/sciadv.abo7490" rel="nofollow noopener noreferrer" target="_blank">https://www.science.org/doi/10.1126/sciadv.abo7490</a>
