Data‐Driven Satellite Drag Modeling Without Dynamic Knowledge of the Atmosphere
Space Weather, Volume 24, Issue 2, February 2026.Abstract Increasing congestion in low Earth orbit (LEO) from new satellite deployments and a growing debris population has made accurate orbital trajectory prediction essential for anticipating and avoiding potential collisions on a regular basis. Atmospheric drag is usually the dominant source of propagation error across much of LEO, especially during

Role of Dead‐End Regions and Transmitting Pores in Mixing and Reactivity in Unsaturated Porous Media
Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Mixing‐limited reactions in unsaturated porous media are controlled by complex pore‐scale processes arising from air and water phases coexistence. Decreasing water saturation increases flow heterogeneity, creating preferential flow paths and dead‐end regions (DER) that alter solute distribution and reaction efficiency.

Epidemiology of Maxillofacial Injuries in the Swords of Iron War: Insights From a National Registry
Dental Traumatology, Volume 42, Issue 1, Page 71-78, February 2026.ABSTRACT Background Maxillofacial injuries (MFI) in warfare present significant challenges due to the concentration of vital structures in the facial region and the high‐energy mechanisms of injury. This study analyzes the epidemiology, severity, and outcomes of MFI during the Swords of Iron conflict using data from the Israeli National Trauma Registry.

Kyklos, Volume 79, Issue 1, Page 17-23, February 2026.ABSTRACT This article proposes that wars are fought to bring about and monitor mutual reductions of overinvestment in broadly defined military preparedness. If two potential combatants are overinvested in military preparedness, it is in their individual interest to scale down in order to use their resources in politically more desirable ways.

Sampling the volcanic plumes at Io: Impact speeds and shock conditions
Meteoritics &Planetary Science, Volume 61, Issue 2, Page 241-271, February 2026.Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.ABSTRACT The Milano‐Cortina 2026 Winter Olympics present an opportunity to synthesize evolving paradigms in endurance training within the broader context of long‐term athlete development. As Olympic winter sports span from endurance‐limited events to disciplines in which aerobic fitness primarily serves as a feeder capacity, a single training model is ...

The Journal of Physiology, Volume 604, Issue 3, Page 1428-1446, 1 February 2026.Abstract figure legend The brain is a major energy consumer relying primarily on carbohydrates. This exceptional metabolic demand suggests that its functional state, which includes cognitive processes such as motor memory acquisition and retention, should be observable in the body's systemic metabolism. To explore this link, we investigated whether the
