A Gallium Nitride Transistor Withstood More Than 3,400 Volts

EPFL researchers built a gallium-nitride transistor on silicon that withstood more than 3.4 kilovolts while keeping resistance low. Its charge-balanced design could shrink high-voltage power converters, but it remains a laboratory device without demonstrated converter-level efficiency, manufacturing yield or long-term field reliability.

Engineered tRNA Restored a Missing Protein in Cystic Fibrosis Models

Researchers engineered transfer RNA and a lipid carrier to restore functional CFTR protein in cells, mice and patient-derived cystic fibrosis organoids carrying premature stop mutations. The platform could eventually address similar errors across many genes, but it remains preclinical and has not been tested as a treatment in people.
