For the first time, MIT researchers measured the dynamics of chromatin movement over an extended period of time, ranging from the scale of microseconds to hours. The findings offer insight into how gene expression is regulated, as well as how chromatin segments come together for other processes such as DNA repair.

New research from the UC Davis School of Medicine and collaborating institutions solves the mystery of how mutations in the same gene can cause serious heart disease or severe skin disease — but never both. The findings were published in the Proceedings of the National Academy of Sciences (PNAS). 

Penn Engineers have developed a new way to use AI to solve inverse partial differential equations (PDEs), a particularly challenging class of mathematical problems with broad implications for understanding the natural world. The advance, which the researchers call “Mollifier Layers,” could benefit fields as varied as genetics and weather forecasting, because inverse PDEs help scientists work backward from observable patterns to infer the hidden dynamics that produced them.
