Mechanochemical‐Induced Swelling–Activation of a Gastric‐Deployable 4D‐Printed Polypill Inspired by Natural Hygromorphic Actuators

Advanced Intelligent Systems, Volume 7, Issue 4, April 2025.
Lifelong medication in patients with chronic diseases compromises treatment adherence, therapeutic outcomes, and quality of life. The bioinspired 4D‐printed polypill self‐deploys upon ingestion, constricting passage through the pylorus while at the same time providing sustained drug release, serving as drug delivery platform with applications in both ...

Reactive lymphoid hyperplasia of the liver: A case report featuring characteristic nodular and perinodular enhancement

Radiology Case Reports
A 53-year-old female with primary biliary cholangitis was referred for the evaluation of a hepatic nodule identified during routine imaging. Ultrasonography revealed a homogeneous, hypoechoic, 18 mm nodule in segment 3 of the liver. On dynamic CT and MRI,

Impacts Into Titan's Methane‐Clathrate Crust as a Source of Atmospheric Methane

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Titan is the only icy satellite in the solar system with a dense atmosphere. This atmosphere is composed primarily of nitrogen with a few percent methane, which supports an active, methane‐based hydrological cycle on Titan. The presence of methane, however, is intriguing, as its lifetime is likely much shorter than the age of the solar system ...

Gravity and Radio Science Investigation at the Moons of Uranus to Reveal Subsurface Oceans and Characterize Interior Structures

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract The prospect that the five major moons of Uranus could host subsurface oceans makes them high‐priority targets for future exploration. Different techniques can be used to search for deep oceans in these objects. Here, we focus on ocean detection and characterization from measurements of the moons' response to the gravitational tides and ...

Forward Modeling of Bending Angles With a Two‐Dimensional Operator for GNSS Airborne Radio Occultations in Atmospheric Rivers

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.
Abstract The Global Navigation Satellite System (GNSS) airborne radio occultation (ARO) technique is used to retrieve profiles of the atmosphere during reconnaissance missions for atmospheric rivers (ARs) on the west coast of the United States. The measurements of refractive bending angle integrate the effects of variations in refractive index over ...
