I had a wonderful time in my hometown of Porto for my first conference on the history, philosophy, and social studies of biology. Grateful for the insights and conversations with biologists, philosophers, and other experts. Left with plenty to ponder about the nature and evolution of ageing.

Transcriptomic entropy reveals tissue-specific patterns in aging and predicts cancer progression Aging and cancer share complex molecular mechanisms, yet distinguishing between causative factors and byproducts remains challenging. Here, we investigated the role of transcriptomic entropy in aging and cancer processes by analyzing RNA-sequencing data from thousands of human and mouse samples. We found that entropy changes during aging are highly tissue-specific, with some tissues showing increased entropy while others exhibit decreased or stable entropy levels. Transcriptomic entropy strongly correlates with age-related processes, showing positive associations with proliferation, cellular senescence, and somatic mutation burden, while negatively correlating with stemness. Surprisingly, cellular reprogramming also increases transcriptomic entropy. In cancer, we observed that primary tumors generally display higher entropy than normal tissue, with entropy levels further increasing in metastatic stages. Notably, treatment-resistant tumors showed distinct entropy patterns, with acquired resistance associated with increased entropy, while primary resistance and immediate post-treatment responses showed decreased entropy. Higher entropy levels predicted poor survival outcomes in multiple cancer types, suggesting its potential as a prognostic marker. Furthermore, differential expression analysis revealed that entropy-associated genes are enriched in developmental processes and depleted in metabolic pathways, indicating a possible link to cellular dedifferentiation. Finally, we found increased entropy in various age-related diseases beyond cancer, suggesting that transcriptomic disorder may be a common feature in age-related pathologies. Our findings establish transcriptomic entropy as a fundamental parameter in aging and cancer progression, offering new insights into disease mechanisms and challenging the current view that increased disorder is always detrimental. ### Competing Interest Statement The authors have declared no competing interest.

Reporting quality, effect sizes, and biases for aging interventions: a methodological appraisal of the DrugAge database Though interest has grown significantly over the past decades in interventions that may slow the aging process, most evidence for these interventions still comes from experiments in non-human animals. These studies may suffer from design, quality and reporting issues. The quality and reporting of preclinical studies have not yet been studied systematically in anti-aging research. Here we analyzed the DrugAge database, assessing reporting study quality, bias and effect sizes across 667 anti-aging preclinical studies. We found significant shortcomings in reporting of crucial design features such as randomization and blinding, as well as large variation in reporting quality and effects across species. Non-mammal findings typically did not translate to mammals. Although anti-aging interventions may have different effects depending on when they are started, most studies began giving the intervention under investigation very early in the organism's lifespan. Our findings suggest there is substantial room for improvement in preclinical anti-aging research. ### Competing Interest Statement The authors have declared no competing interest.

Using DrugAge, we evaluated quality, effect sizes, and biases.

Can senolytics slow aging?

Recent clinical trials and the largest mouse study of senolytics to date have failed to support this notion, raising questions regarding the future of senolytics as an anti-aging therapy.

Combining two drugs (trametinib and rapamycin) resulted in one of the greatest life-extensions observed in mice - 27% (males) and 29% (females).

Both are anticancer drugs and treatment reduced tumor load, though other benefits were observed (eg reduced inflammation).
