MIT researchers developed a “computational violin” — the first computer simulation that captures the detailed physics of the instrument and realistically produces the sound of a violin when its strings are plucked. Violin makers could use the model to test how a violin might sound when certain dimensions or properties are changed.

New technology enables the insertion of a large segment of DNA into a genome, potentially expanding gene therapy treatment from cancellation of disease-causing mutations to replacement of an entire gene, scientists say. Reporting today (April 29, 2026) in Nature, the researchers describe building upon a technique called prime editing by inserting DNA that attaches to the genome through a series of overlapping flaps. This method, which they call a prime assembly approach, avoids a bottleneck in the gene therapy field – a double-strand break to the donor DNA that can cause toxicity and kill cells.

The American Hospital Association (AHA) and the West Health Institute today announced a new three-year initiative to help hospitals and health systems operationalize and scale proven technologies across care environments to improve patient outcomes and support care teams.
