Space science: Gigantic auroras revealed: Unveiling solar dynamics during rare solar wind disappearance

http://www.ru.uec.ac.jp/randi/research-highlights/research/202501.html

An international research team led by Keisuke Hosokawa and including Takuo Tsuda of the University of Electro-Communications, in collaboration with Kyoto University and the National Institute of Polar Research has captured a rare and strikingly large aurora spanning the Arctic region. This unprecedented observation occurred during an unusual solar phenomenon where the solar wind, a stream of charged particles that typically interacts with the Earth's magnetosphere to create auroras, almost completely vanished. The study, published in Science Advances provides new insights into how auroras can form in the absence of normal solar wind conditions and reveals unexpected complexity in auroral behavior under these rare circumstances.

Face recognition: Voice coming into the picture

http://www.ru.uec.ac.jp/randi/research-highlights/innovation/202501.html

During the COVID-19 pandemic, requiring people to wear facemasks in public places and shops was an important measure taken by governments all over the world. The requirement is no longer in place, but in Japan and elsewhere, many people still choose to wear a facemask as a precaution, and it is expected that facemasks will remain commonplace. This poses a problem to security and identification systems, as it is difficult to correctly automatically identify a person who's half face is covered by a mask. To address this situation, computational methods capable of 'inpainting' masked face images have been developed, with some degree of success. Now, Yuichi Sei and colleagues from The University of Electro-Communications, Tokyo, have created a method that not only uses visual information, but also audio — the person's voice — to reconstruct a masked face. The approach enables face shape restoration with improved quality.
