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)

Wolves and dogs recruit human partners in the cooperative string-pulling task ( www.nature.com )
Abstract In comparison to non-human animals, humans are highly flexible in cooperative tasks, which may be a result of their ability to understand a partner’s role in such interactions. Here, we tested if wolves and dogs could flexibly adjust their behaviour according to whether they needed a partner to solve a cooperative...

An interesting study regarding the decline of cardiovascular capacity when minimizing activity level to the least amount possible. ( www.ahajournals.org )
For the initial evaluations in 1966, 5 healthy 20-year-old male volunteers were assessed at baseline, spent 3 weeks at complete bed rest with no weight bearing allowed (similar to clinical treatment of acute myocardial infarction at the time), and then underwent 8 weeks of intensive endurance training. Cardiopulmonary function...
References & resources about non-RNA-based self-replication? ( lemmy.ca )
We identify “life” with the capability of self-replication plus some other features. In other conditions, for instance on other planets, it could be possible for self-replication to happen in a way different from the RNA/DNA-based one....
