Ship‐Based GNSS Tsunami Detection: Pilot Network Demonstration

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract We demonstrate the potential for ship‐based GNSS systems to contribute to tsunami warning. We built a pilot network of 10 ships—8 commercial and 2 research vessels—equipped with a tsunami detection package consisting of a geodetic‐grade GNSS antenna and receiver, and satellite internet communications.

Verification and Mitigation of Proton‐Induced Non‐Ionizing Damage in Perovskite Solar Cells for Space Applications

Advanced Energy Materials, Volume 16, Issue 30, 12 August 2026.
Metal‐halide perovskite solar cells offer high‐efficiency power for orbital missions but suffer from permanent proton‐induced degradation. This work identifies non‐ionizing energy loss (NIEL) as the primary driver of irreversible failure, inducing atomic displacements and microcracks in the high‐fluence regime. Through energy‐tuned mapping and scalable

The FemTech revolution: Unlocking the potential of new technology for optimizing pregnancy outcomes in low‐ and middle‐income countries and remote areas

International Journal of Gynecology &Obstetrics, Volume 174, Issue 2, Page 530-553, August 2026.
Abstract Maternal and neonatal mortality and morbidity rates uncover major global health disparities. Despite ongoing efforts, the rates of maternal and neonatal complications remain substantially higher in low‐ and middle‐income countries (LMICs) compared to high‐income countries (HICs). These high rates are the result of several unmet needs in LMICs,
