Advanced Science, EarlyView.A programmable passive digital shutter based on multiphase liquid–liquid interface dynamics is introduced for precise fabrication of hydrogel microfibers. By modulating the shutter operation, microfibers with tunable geometry—including linear, helical, tadpole‐like, and spherical forms—are produced.

Stable and habitable systems with two giant planets
, 2010 We have studied planetary systems which are similar to the Solar System and built up from three inner rocky planets (Venus, Earth, Mars) and two outer gas giants.

Wide‐Range Adaptive Metal Oxide for Hydrogen Sulfide Detection From Earth to Space‐Like Environments
Advanced Science, EarlyView.This work presents a gas sensing platform based on Cu‐doped SnO2 microspheres that operates reliably from ambient to space‐like conditions. The sensor maintains performance across vacuum and cryogenic environments, bypassing traditional oxygen‐mediated mechanisms, utilizing direct chemisorption and interfacial charge transfer.

Ringed versus Ringless Worlds: How Poynting–Robertson Drag Shapes Rings across the Solar System
The Astrophysical Journal LettersPlanetary rings are not only ubiquitous around the giant planets in the outer solar system, but have also been discovered around several small distant bodies. In contrast, no rings have been observed around any inner solar system objects.

Multiple-Planet Scattering and the Origin of Hot Jupiters
, 2011 Exoplanets show a pile-up of Jupiter-size planets in orbits with a 3-day period. A fraction of these hot Jupiters have retrograde orbits with respect to the parent star's rotation.

Meteorology of the Outer Planets [PDF]
International Astronomical Union Colloquium, 1982 One of the fundamental problems in atmospheric physics is concerned with providing improved weather forecasts for the Earth and predicting the future climate of our planet. However, this is a particularly difficult task since the meteorology of the Earth is affected by a wide range of physical factors - clouds, oceans, continents, polar caps, deserts ...

THYME. XIII. Two Young Neptunes Orbiting a 75 Myr Star in the Alpha Persei Cluster
The Astronomical JournalYoung planets with mass measurements are particularly valuable in studying atmospheric mass-loss processes, but these planets are rare and their masses difficult to measure due to stellar activity. We report the discovery of a planetary system around TOI-

Deformation Driven Suction Cups: A Mechanics‐Based Approach to Wearable Electronics
Advanced Science, EarlyView.Deformation‐driven suction cups enable robust, reversible adhesion of wearable electronics to human skin spanning wide mechanical compliance, without adhesives or tight straps. By integrating mechanics modeling, experiments, and contact mechanics theory, this work reveals how cup geometry, substrate compliance, and interfacial adhesion govern suction ...
