Neuromorphic Computing with Memcapacitors: Advancements, Challenges, and Future Directions

Advanced Electronic Materials, Volume 11, Issue 18, November 4, 2025.
Neuromorphic computing reduces energy costs by integrating memory and processing in event‐driven architectures, achieving energy usage as low as 10–30 pJ per operation for memcapacitor‐based synapses. Memcapacitors are reviewed as strong contenders for neuromorphic computing, enhancing AI acceleration through charge‐based computations, high resistance,

Mercury's Altered Magnetosphere During a Sub‐Alfvénic ICME Event: MESSENGER Observations and Inferred Asymmetric Alfvén Wing Formation From Global MHD Simulations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract We present observations of a rare configuration of Mercury's magnetosphere in response to sub‐Alfvénic upstream conditions, driven by an interplanetary coronal mass ejection (ICME) that impacted the planet on 1 May 2013. Using data from the Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft, supported by a ...

Clouds and Hazes in GJ 1214 b’s Metal-rich Atmosphere

The Astronomical Journal
The sub-Neptune GJ 1214 b has an infamously flat transmission spectrum, likely due to thick aerosols in its atmosphere. A recent JWST/MIRI spectroscopic phase curve of GJ 1214 b added to this picture, suggesting a highly reflective and metal-rich ...

Climates of Warm Earth-like Planets I: 3-D Model Simulations

, 2018
We present a large ensemble of simulations of an Earth-like world with increasing insolation and rotation rate. Unlike previous work utilizing idealized aquaplanet configurations we focus our simulations on modern Earth-like topography.

Two-dimensional Models of Microphysical Clouds on Hot Jupiters. I. Cloud Properties

The Astrophysical Journal
We present a new two-dimensional, bin-scheme microphysical model of cloud formation in the atmospheres of hot Jupiters that includes the effects of longitudinal gas and cloud transport.

Survey and Modeling of Windblown Ejecta Deposits on Venus

AGU Advances, Volume 6, Issue 5, October 2025.
Abstract Venus' thick atmosphere rotates in the same direction as the solid body, but ∼60 times faster. This atmospheric superrotation has produced dozens of windblown ejecta deposits (“parabolas”) on the surface of Venus. The formation and modification of parabolas is an interplay between impacts, aeolian modification, and atmospheric dynamics.

Flow Regimes in Hot Jupiter Atmospheres: Insights from Anelastic Models

The Astrophysical Journal
Hot Jupiters are Jupiter-sized exoplanets with close-in orbits, characterized by extreme day–night temperature contrasts due to synchronous rotation.
