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

Nanomachines are plagued by their short lifespans and the looming chaos in the environment. This group at TUM used a new tubular design made from DNA to keep the machine together, but the chaos out. Continue reading Submicroscopic Pistons Open a New Chapter for Nanomachines
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
