DNA replication errors during cell division cause monozygotic twins to diverge from each other even during the earliest stages of development, a new study finds.
The Sloan Kettering researcher used mutagenic screening to probe genes and molecular pathways, including Toll and Hedgehog, essential to development in fruit flies and mice.
Enhancers, short regions of DNA that direct gene expression, of species separated by 700 million years of evolution worked interchangeably, according to a new study.
Understanding biology’s software—the rules that enable great plasticity in how cell collectives generate reliable anatomies—is key to advancing tissue engineering and regenerative medicine.
Working with a virus that infects bacteria, the Stanford University biochemist and developmental biologist helped to develop a way to stitch DNA together, a discovery that gave rise to genetic engineering.
Wing development in females is environmentally controlled, but in males, an insertion on the sex chromosome appears to dictate whether the insects grow wings, according to a study.
To see if the spiky fish shares signaling pathways found in other organisms, scientists scooped up specimens during a mating frenzy on the shores of Japan.
Rhesus monkeys engineered to express a human gene reportedly show delayed brain development and better short-term memory. Fellow scientists are raising ethical red flags.
