Antiferromagnets: Micro-ARPES uncovers exotic NdSb surface states
Advanced Institute for Materials Research (AIMR), Tohoku UniversityAIMR researchers used micro-focused ARPES to identify domain-specific surface states in antiferromagnetic NdSb that disappear above 16 K. This suggests bulk spin order induces these states through symmetry-breaking, potentially enabling control of surface electrons for applications in spintronics and quantum technologies.

The University of Osaka and research partners launch open-source quantum computer OS
The University of OsakaBusiness Announcement
While small-scale open-sourcing efforts had been attempted in the past, this project has realized one of the largest-scale open-sourcing initiatives globally. This software can customize set-up through operation to meet users’ needs. This is expected to pave the way for practical quantum computers in the future and contribute to solving social issues through their application.

Comprehensive chemical analysis of codonopsis lanceolata roots and the vasodilatory effects of its major compound, lancemaside A
Toho UniversityPeer-Reviewed Publication
A research group led by Associate Professor Takashi Kikuchi and Professor Wei Li from the Department of Pharmacognosy at the Faculty of Pharmaceutical Sciences, Toho University, along with Professor Atsushi Sugiyama from the Department of Pharmacology at the Faculty of Medicine and Industry-Academia Collaboration Advisor Katsuhiko Ito, has analyzed the chemical compounds of the roots of Codonopsis lanceolata (commonly known as “Tsuruninjin”) grown in Nagano Prefecture. Their findings have revealed the compounds of the plant and, in particular, demonstrated that its major compound, lancemaside A, exhibits vasodilatory effects, suggesting that Codonopsis lanceolata could be effectively utilized as a health-promoting material in the future.
This research was published in the academic journal Chemistry on January 6, 2025.

Hope for a complete cure for hepatocellular carcinoma: Combining lenvatinib and pembrolizumab with transarterial chemoembolization improves efficacy in treating hepatocellular carcinoma
Kindai UniversityPeer-Reviewed Publication
An international collaborative research group led by Prof. Masatoshi Kudo, MD (Chair, Department of Gastroenterology and Hepatology, Kindai University Faculty of Medicine) conducted a multicenter, randomized, double-blind, phase 3 study and demonstrated that the combination of the molecular targeted agent lenvatinib and the immune checkpoint inhibitor pembrolizumab in addition to the conventional treatment of transarterial chemoembolization (TACE) in patients with unresectable non-metastatic hepatocellular carcinoma (HCC) significantly extended progression-free survival and showed a trend toward extending overall survival compared to TACE alone. Based on the results of this study, it is anticipated that lenvatinib plus pembrolizumab, in combination with TACE, will become the standard of care for patients with unresectable non-metastatic HCC and may lead to a complete cure.

VR study reveals how pain and fear weaken sense of body ownership
Hiroshima UniversityPeer-Reviewed Publication
A study from Hiroshima University found that when people were told to imagine their virtual bodies in pain, their brains resisted the illusion of ownership. Their findings could provide insights into why some people may struggle with feeling connected to their own bodies, particularly in contexts involving depersonalization or negative physical states.
