Atmospheric Escape From Three Terrestrial Planets in the L 98-59 System
The Astrophysical JournalA critically important process affecting the climate evolution and potential habitability of an exoplanet is atmospheric escape, in which high-energy radiation from a star drives the escape of hydrogen atoms and other light elements from a planet’s ...

Embedded Direct Ink Writing of Thermoset and Elastomeric Polymers via Frontal Polymerization
Advanced Functional Materials, EarlyView.Embedded frontal polymerization direct ink writing (FP‐DIW) combines frontal ring‐opening metathesis polymerization with embedded 3D printing to decouple deposition from curing. A yield‐stress support bath stabilizes low‐viscosity inks, while on‐demand thermal initiation enables controlled front propagation. This approach expands the accessible feature

Different types of star-planet interactions [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractStars and their exoplanets evolve together. Depending on the physical characteristics of these systems, such as age, orbital distance and activity of the host stars, certain types of star-exoplanet interactions can dominate during given phases of the evolution.

Tidal Migration of Exoplanets around M Dwarfs: Frequency-dependent Tidal Dissipation
The Astrophysical JournalThe orbital architectures of short-period exoplanet systems are shaped by tidal dissipation in their host stars. For low-mass M dwarfs whose dynamical tidal response comprises a dense spectrum of inertial modes at low frequencies, resolving the frequency

Myogenic Fusogen‐Engineered Lipid Nanoparticles Enhance mRNA Delivery in Skeletal Muscle
Advanced Functional Materials, EarlyView.This study reports a biomimetic strategy of engineering full‐length Myomaker, a muscle‐specific fusogen, into lipid nanoparticles (LNPs) to harness the native myoblast fusion capability for skeletal muscle mRNA delivery. The resulting Mymk‐LNPs enhance transfection in differentiating myocytes and enable Cre‐mediated reporter activation in injured ...

Capture into Apsidal Resonance and the Decimation of Planets around Inspiraling Binaries
The Astrophysical Journal LettersTransiting circumbinary planets (CBPs) are conspicuously rare and entirely absent around stellar binaries with periods ≤7 days. Here we exploit a secular resonance to stimulate the orbit of a CBP into strong, disruptive interactions with the host binary.

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments
Advanced Functional Materials, EarlyView.We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Direct imaging and astrometric detection of a gas giant planet orbiting an accelerating star
, 2023 Direct imaging of gas giant exoplanets provides information on their atmospheres and the architectures of planetary systems. However, few planets have been detected in blind surveys with direct imaging.
