Advanced Materials, EarlyView.2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

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.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics
Advanced Materials, EarlyView.“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Carving the Edges of the Rocky Planet Population
The Astrophysical Journal LettersShort-period planets provide ideal laboratories for testing star–planet interaction. Planets that are smaller than ∼2 R _⊕ are considered to be largely rocky, either having been stripped of or never having acquired the gaseous envelope.

Astronomy & AstrophysicsBinary systems with ultrashort-period planetary-mass companions are expected to radiate continuous gravitational waves (GWs). However, earlier studies found that the detectability of such systems by the Laser Interferometer Space Antenna (LISA) is ...

An Earth-sized Planet on the Verge of Tidal Disruption
The Astronomical JournalTOI-6255 b (GJ 4256) is an Earth-sized planet (1.079 ± 0.065 R _⊕ ) with an orbital period of only 5.7 hr. With the newly commissioned Keck Planet Finder and CARMENES spectrographs, we determine the planet’s mass to be 1.44 ± 0.14 M _⊕ .

Advanced Materials, EarlyView.Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

The Near-ultraviolet Transit of XO-3 b
The Astronomical JournalNear-ultraviolet (NUV) measurements of exoplanet transits offer a means to probe atmospheric escape, cloud formation, and planetary magnetic fields. We examine a 2024 XMM-Newton Optical Monitor NUV observation of the transit of XO-3 b, a massive hot ...
