Trophoblasts, collected from the mother during a blood draw, can determine fetal genetic abnormalities currently diagnosed through amniocentesis or chorionic villi sampling.
Viruses that infect plants and occasionally insects appear to cause infection with a divide-and-conquer strategy, multiplying separate segments of genetic material in different host cells.
Two studies contest the idea that the noncoding sequences are just “junk DNA,” demonstrating that they play important roles in the regulation of cell growth.
Using CRISPR and other tools, scientists are modifying DNA methylation, histone marks, and other modifiers of gene expression to understand how they affect health and disease.
An entrepreneurial attitude helped this Vienna-based researcher begin to unravel the complex receptor network that Arabidopsis uses to develop and defend itself.
Elaine Fuchs has worked on adult stem cells since before they were so named, figuring out how multipotent epidermal cells renew or turn into skin or hair follicles.
