Scientists safely correct a disease-causing mutation in early stage human embryos with gene editing.
A study led by Duke-NUS Assistant Professor Adam Claridge-Chang identified effective inhibitors of brain activity in the important biomedical model Drosophila melanogaster, the common vinegar fly. In this work, flies were genetically modified to express anion channelrhodopsins (ACRs), proteins ...
Multiplexed optogenetic control, using Photo-inhibitable Vav2 (PA-Vav2) and Photo-inhibitable Rac1 (PI-Rac1) in the same cell.Upon irradiation, area and roundness changed as they did in response to PA-Vav2 alone, but edge dynamics were clearly reduced, unlike response to either PA-Vav2 alone or ...
With Nessa Carey
Why your DNA is not your destiny. Molecular biologist Nessa Carey presents an introduction to epigenetics and explains how it shapes life.DNA is a vitally important starting point for life, but it's how it's used by cells and organisms that is really important. Epigenetics is a rapidly moving ...
