Noise Induces Hopping between NF-κB Entrainment Modes

Noise Induces Hopping between NF-κB Entrainment Modes

On the cover of the December Cell Systems issue, IGSB Faculty member Savas Tay, and others, observe that when NF-κB oscillations are entrained by periodic tumor necrosis factor (TNF) inputs in experiments, NF-κB exhibits jumps between frequency modes, a phenomenon called “cellular mode-hopping.” By comparing stochastic simulations of NF-κB oscillations to deterministic simulations conducted inside and outside the chaotic regime of parameter space, they show that noise facilitates mode-hopping in all regimes.

A big data look at improving scientific research: A Q&A with Andrey Rzhetsky

A big data look at improving scientific research: A Q&A with Andrey Rzhetsky

Of all the possible experiments available in biomedical research, only a small subset are ever tackled by scientists. This is in part due to institutional and cultural pressures that lead researchers to avoid risk-taking and choose inefficient research strategies, according to a new study based on a computational analysis of millions of patents and research articles. Despite increased opportunities for groundbreaking experiments, most scientists choose conservative research strategies to reduce personal risk, which makes collective discovery slower and more expensive, conclude Andrey Rzhetsky, PhD, professor of medicine and human genetics and director of the Conte Center for Computational Neuropsychiatric Genomics, and his colleagues.
