Falling Flies

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 ...

Epigenetics - packaging artists in the cell

Methyl attachments to histone proteins determine the degree of packing of the DNA molecule. They thereby determine whether a gene can be read or not. In this way, environment can influence the traits of an organism over generations.

Multiplexed optogenetic control, using PA- Vav2 and PI-Rac1 in the same cell

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 ...

What is Epigenetics?

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 ...
