Substellar Landmass Fraction and Atmospheric Circulation Regimes of Ultrashort-period Rocky Planets around White Dwarfs

The Astrophysical Journal
White-dwarf (WD) systems are attractive candidates for planet detection and follow-up transmission spectroscopy campaigns. However, the climate and habitability of terrestrial planets around WDs still remain largely elusive, and a central question lies ...

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

Advanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

The New Titan Planetary Climate Model. II. Titan’s Haze and Cloud Cycles

The Planetary Science Journal
Observations of Titan have long revealed the presence of seasonal cycles, including haze, clouds, and gases. The lack of information on the different processes that govern these cycles prevents us from understanding all the phenomena taking place in ...

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields

Advanced Science, EarlyView.
Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

The New Titan Planetary Climate Model. I. Seasonal Variations of the Thermal Structure and Circulation in the Stratosphere

The Planetary Science Journal
Observations of Titan through Cassini’s mission allowed Saturn’s moon’s stratospheric thermal structure and composition to be mapped over half a Titan year.

Generalized Mechanism Model for Ecosystem Hysteresis

Advanced Science, EarlyView.
A simplified model examines ecosystem transitions into alternative states after disturbances by leveraging positive and negative feedbacks. It identifies critical tipping points and quantifies hysteresis. Tests conducted on lakes, grasslands, and pitcher‐plant leaves align closely with empirical data and enable the prediction of recovery trajectories ...

Impacts of Atmospheric Carbon Species and Stellar Type on Climates of Terrestrial Planets

The Planetary Science Journal
The climates of terrestrial planets are largely determined by the composition of their atmospheres and the spectral types of their host stars. Previous studies suggest that a wide range of carbon species abundances (CO _2 , CO, and CH _4 ) can result ...

“Active Planetary Cover” Concept and Long-Term Evolution of Planetary Climate [PDF]

, 2003
At the beginning of XIX. century J.-B. Lamarque had introduced the term “biosphere”. In accordance with his definition the biosphere is a “scope of life” and it is an external cover for the Earth. In 1875 E. Suss, who also distinguished the biosphere as one of the Earth covers, introduced the same term in geology. But V.

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

Advanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

Impact of Annually Variable Dust Activity on the Recession of the Martian South Polar Seasonal Cap

The Astronomical Journal
Suspended dust is a vital component of Martian climatic system and its temporal-spatial variation can influence the recession of the South Polar Seasonal Cap (SPSC).
