Whereas theories of ecological diversity mostly consider continuously supplied nutrients, a seasonal model uncovers a general mechanism that controls diversity and reconciles conflicting experimental findings.
Proper development depends on establishing precise gene expression patterns in spite of the inherent noise in transcription, shadow enhancers buffer this noise by binding distinct input transcription factors.
A biomimetic and patient-specific Glioblastoma-on-a-Chip microphysiological system provides an avenue for personalized screening of PD-1 immunotherapy and novel combinational therapies that maximize therapeutic outcomes in Glioblastoma patients.
Upon deletion of threonine deaminases, biosynthesis of isoleucine is rescued by two promiscuous reactions, one emerges under aerobic conditions and the other is naturally active under anaerobic conditions.
Analyses of allelic- and socially-biased gene expression reveal that suppressed recombination causes most of the expression differences in the social supergene, with only few differences due to socially antagonistic selection.
A mathematical model for a popular biological diversity mechanism, cyclic dominance, is more likely to emerge by assembly than by evolutionary diversification, which rationalizes why few empirically studies find it.
Propagation, speed and shapes of genetic waves of expression during development can be modeled by a simple interplay between two transcriptional modules (dynamic/static), which explains robustness and precision of patterning.
