A largely overlooked space between cells in women’s brains — called the extracellular matrix (ECM), which is highly abundant in the hippocampus — may hold the key to understanding memory loss tied to estrogen decline after menopause, reports a new preclinical Northwestern Medicine study. Scientists have traditionally focused on studying brain cells such as neurons and glial cells and have paid much less attention to the space between the cells. This is the first study to examine estrogen loss in the ECM. The findings provide new insight into how estrogen loss may affect the aging female brain and could help explain why women are at higher risk for AD. These findings suggest a possible new treatment approach focused on restoring the brain’s supportive environment — the ECM — to help protect memory and fight this devastating disease.
Astronomers using the James Webb Space Telescope observed a large group of galaxies which had been discovered in the early Universe by the Subaru Telescope. The observations show that even as early as 1.2 billion years after the birth of the Universe, the local environment was already influencing galaxy growth. These results provide new insights into the development of galaxies throughout the history of the Universe.
Scientists from Israel and Germany have completed integration and testing of the first nanosatellite in the CloudCT network, an innovative space mission designed to improve climate predictions through three-dimensional imaging of clouds. The satellite is scheduled for launch from California in June 2026, with ten additional satellites planned for 2027 if the precursor mission succeeds.
Led by Prof. Ilan Koren of the Weizmann Institute of Science, Prof. Yoav Schechner of the Technion – Israel Institute of Technology, and Prof. Klaus Schilling of Zentrum für Telematik, the project introduces a novel cloud observation method inspired by computed tomography (CT) used in medicine. The system combines simultaneous multi-angle satellite imaging, polarization-sensitive cameras, and AI-based analysis to reconstruct the internal structure and microphysical properties of clouds in unprecedented detail.
Researchers say the mission addresses major uncertainties in climate and weather modeling by capturing small cloud formations that are difficult to observe with existing remote-sensing technologies. The miniature precursor satellite weighs about 4 kilograms and must autonomously orient itself toward target clouds with extremely high precision.
The project was supported by a European Research Council (ERC) Synergy Grant.
