Finding DNA Tags in AAV Stacks
Mariella Bodemeier Loayza Careaga, PhD | Mar 7, 2024 | 8 min read
Ten years ago, scientists put DNA barcodes in AAV vectors, creating an approach that simplified, expedited, and streamlined AAV screening.

My Daughter’s First Pet—the Next Big Model Organism?
Christie Wilcox, PhD | Jul 15, 2021 | 10+ min read
Bettas were likely the first fish welcomed into human homes. Now, scientists are welcoming them into the lab to learn how genes dictate their appearance and behavior.

In Vivo Gene Therapy Cures Infertility in Mice
Dan Robitzski | May 2, 2022 | 2 min read
Mice rendered infertile through ovary cell–targeting mutations gave birth to seemingly normal offspring through natural mating after a virus-based gene therapy was injected into their ovaries.

Early-Life Stress Exerts Long-Lasting Effects Via Epigenome
Asher Jones | Mar 18, 2021 | 5 min read
In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.
Finding a Mate
Barbara Cunningham | Apr 1, 2001 | 9 min read
Available Two-hybrid Systems Graphic: Leza BerardoneGenome sequencing has produced a vast supply of proteins in need of a functional identity. One way to identify a protein's function is to identify its interacting partners, because proteins often work in pairs or as part of large complexes. Scientists traditionally have used biophysical or biochemical methods (such as affinity chromatography or co-immunoprecipitation) to study protein-protein interactions. More recently, two-hybrid and phage-d

The Extinct Species Within
Christie Wilcox, PhD | Aug 6, 2021 | 10+ min read
The genomes of living animals are littered with DNA from long-gone relatives, providing a lens on evolution, past extinctions, and perhaps even solutions to agricultural problems.
