Genetic and cell biological study indicates that germ cells' connectivity serves as a mechanism to increase the sensitivity of germline to DNA damage, protecting the genome of gametes, in the Drosophila testis.
Horizontal gene transfer (HGT) helps slightly beneficial genes persist in microbial populations, incentivising cells to invest in costly DNA uptake, even in the presence of harmful selfish genetic elements.
A model based on empirical parameter estimates predicts that arresting cancer cell growth by less than 1% per day will produce optimal outcomes in preventing life-threatening cancers, and that such preventive measures are generally more successful than post-diagnostic interventions.
In a minimalistic, generic model of competitive communities in which evolution is constrained by life-history trade-offs, stable biodiversity emerges with species adapted to different functional niches.
Computational models and software connect metagenomics to metabolic network reconstruction, assess metabolic complementarity between species, and identify critical species associated to functions of interest.
