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
Scientists have discovered another piece in the puzzle of how tabby cats get their stripes. Continue reading What Makes a Cat a Tabby?
Asexual species do not have genetic variability like humans, and most animals, do. Despite that, they can still adapt to environmental changes using modifications to their DNA known as epigenetic changes. Continue reading Asexual Species Can Adapt to their Environment Even Without Changing their DNA
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
The DNA from children of Chernobyl survivors has been sequenced and does not show higher levels of mutations than other children. Continue reading Children of Chernobyl Survivors Don’t Show Excess DNA Damage from Disaster
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
Base repair editing may be the cure for a genetic mutation leading to childhood aging syndrome. Continue reading Gene Editing Discovery Could End Childhood Premature Aging Syndrome
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?
Dinosaurs rose and fell, but one foot-long scaly creature — the tuatara — persisted. Recently, the first tuatara genome was sequenced, unlocking insights into the evolution of other reptiles, birds, dinosaurs, and even our own mammalian lineage. Continue reading Not Just Your Ordinary Lizard: The Unique Genome of the Tuatara
Researchers from John Hopkins University recently developed a newly improved gene editing tool that is extremely fast — it allows genes to be edited within just a few seconds! Continue reading New gene editing tool can edit genes within seconds
