Downregulation of transposable elements extends lifespan in Caenorhabditis elegans ( scitechdaily.com )

This study shows that in the nematode Caenorhabditis elegans, the downregulation of active TE families extends lifespan. These findings link DNA activity to aging and opens up new possibilities in medical and biological research for health improvement and age determination. doi.org/10.1038/s41467-023-40957-(open access)

Live birth of chimeric monkey with high contribution from embryonic stem cells ( www.nature.com )

Scientists have created an infant ‘chimeric’ monkey by injecting a monkey embryo with stem cells from a genetically distinct donor embryo. The resulting animal is the first live-born chimeric primate to have a high proportion of cells originating from donor stem cells. However, the monkey had to be euthanized when it was...
