Researchers are developing gene and cell therapies and prosthetics to help patients with blindness regain some vision. The first major prosthetic, the Argus II, was just discontinued. Where will the field go from here?
By engineering cells to translate quadruplet codons instead of the standard triplets, scientists expand the possible amino acids that can be integrated into proteins, paving the way for novel protein-based therapeutics and research tools.
When a research question can’t be answered using the tools available, bioengineer Kiana Aran makes new tools. Recently, she developed a new type of brain-on-a-chip to answer questions about the blood brain barrier.
