Surface-floating instruments developed at APL-UW were air-dropped in the Gulf of Mexico in front of hurricanes Helene and Milton. Their observations of the evolving wave field under a hurricane improve predictions of coastal impacts including storm surge. NAVAL RESEARCH LABORATORY Press Release >>>

Ultrasonic propulsion, an investigational kidney stone treatment for awake un-anesthetized patients, sweeps stone fragments toward the ureter to facilitate their natural passage. Repositioning results in a 70% lower incidence of relapse — urgent medical visit or a subsequent surgery. Time to relapse was also longer by nearly 1.5 year in the treatment group. >>> VIDEO >>>

This is an opportunity for scholars from a variety of academic disciplines to design a research project around problems they are passionate about as they collaborate with and receive mentoring from APL-UW scientists. Two years of support facilitate freedom of inquiry and independent study. >>> APPLY >>>

The Mars rover Perseverance has discovered a rock covered in 'leopard spots' — potential biosignatures of ancient microbial life. Mission spectroscopist Tim Elam and the entire NASA team are thrilled, but urge caution because these structures can have a non-biological origin.

The report showcases some of the amazing feats of science and engineering performed by the Lab's dedicated and talented staff over the past year.
