Mining DNA for Disease Prediction: The polygenic risk score

by Alex Yenkinfigures by Allie Elchert Long before the completion of the Human Genome Project, scientists knew that many common diseases had a genetic component. However, there was debate about the architecture of these genetic effects: were there a few high-effect mutations or thousands of tiny effect mutations spread throughout the genome? Now, in the full swing of the genomics revolution, we can see that … Continue reading Mining DNA for Disease Prediction: The polygenic risk score

Gene Regulatory Networks: From DNA to development

by Samantha Roylefigures by Allie Elchert Have you ever thought about how a single cell can grow into a living, breathing, human? The extraordinary complexity of our thinking brains, wiggling fingers and beating hearts emerges from a single celled zygote, formed from the fusion of egg and sperm. Many of us have heard of DNA, the molecule that contains the instructions for life, but have … Continue reading Gene Regulatory Networks: From DNA to development

It’s Not All about Microbes: Genetics and susceptibility to infections

by Aleks Procherafigures by Shreya Mantri  The past year and a half have been a time of profound uncertainty. We all wish we could gaze into a COVID crystal ball and get answers to our burning questions. Some of us would want to know how long the pandemic will last. Others, however, especially those who have never received a positive result, would likely seek an … Continue reading It’s Not All about Microbes: Genetics and susceptibility to infections

What Does an Evolutionary Biologist Do?

How do you introduce yourself, scientifically? My name is Mia Miyagi, and I’m an evolutionary biologist, which means that I study how the process of evolution works and how that process has generated the incredible biodiversity that we have today. More specifically, I’m a theoretical population geneticist. Population genetics is how we think about evolution and variation across entire populations. In other words, how individuals … Continue reading What Does an Evolutionary Biologist Do?
