LITEs (light-inducible transcriptional effectors) can help researchers
get a handle on not only genes, but also the machinery that surrounds
them, responsible for controlling where and when genes are turned on.
Having the ability to test these epigenetic factors (shown in the
inset) holds much promise for many fields of research, including the
study of neuropsychiatric disease, cognition, cancer, and more.
