Light‐Controlled Exposure of Cancer Cells to Reactive Oxygen Species Using Organic Semiconductor Thin Films

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...

Status and Prospect of Secondary Battery Technologies in Space Applications: Challenges and the Future

open access: yesBatteries &Supercaps, Volume 9, Issue 5, May 2026.
Lithium‐ion batteries used in space applications are exposed to extreme conditions, including radiation, vacuum, wide temperature fluctuations, and long storage times, all of which accelerate degradation. This review article summarizes the main degradation mechanisms affecting battery performance in space environments, including capacity fade ...

TURAAB: A 34‐Year Dust and Atmospheric Regional Reanalysis for the Middle East, North Africa and Mediterranean—First Insights

open access: yesMeteorological Applications, Volume 33, Issue 3, May/June 2026.
TURAAB: A 34‐year dust and atmospheric regional reanalysis for the Mediterranean–MENA region. We present TURAAB, a 34‐year, 6‐km regional reanalysis integrating meteorology and dust for the Mediterranean–MENA domain. The system demonstrates good behavior, aligning closely with observational and reanalysis products. TURAAB provides a high‐value resource

Clouds dissipate quickly during solar eclipses as the land surface cools

open access: yesCommunications Earth & Environment
Clouds affected by solar eclipses could influence the reflection of sunlight back into space and might change local precipitation patterns. Satellite cloud retrievals have so far not taken into account the lunar shadow, hindering a reliable spaceborne ...

Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 1884-1904, May 2026.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Detection of Equatorial Plasma Bubbles Using the COSMIC‐2 Rate of TEC Index

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Equatorial plasma bubbles (EPBs) are large‐scale plasma depletion structures that can disrupt Global Navigation Satellite Systems (GNSS) and other space‐based technologies. Several instruments have been employed to study EPB dynamics, with Total Electron Content (TEC) and Rate of TEC change Index (ROTI) data standing out as valuable parameters
