Ammonia is a chemical essential to many agricultural and industrial processes, but it’s mode of production comes with an incredibly high energy cost. Various attempts have, and are, being made to produce ammonia more efficiently. For the first time, a group including researchers from the University of Tokyo combined atmospheric nitrogen, water and sunlight, and using two catalysts, produced sizable quantities of ammonia without a high energy cost. Their processes mirror natural processes found in plants utilizing symbiotic bacteria.

A research group led by Professor Takahiro Nemoto from the Department of Psychiatry and Neuroscience and the Department of Social Implementation Psychiatry at the Toho University Faculty of Medicine analyzed large-scale clinical data to examine the association between the COVID-19 pandemic and the incidence of anorexia nervosa (ICD-10 classification: F50.0) in young patients in Japan. Their study revealed that the number of patients with anorexia nervosa increased after the onset of the COVID-19 pandemic. This research was published in the international academic journal Medicina (Lithuania) on March 3, 2025.

Researchers at University of Tsukuba have discovered a phenomenon—applying pressure to a copper-chromium Prussian blue analog, which is a compound featuring crystal voids, causes the discharge of water retained within these voids. This material is expected to serve as a novel onsite water production platform for extraction of water solely through pressure application, without temperature or humidity control, even in arid regions.

Researchers from the Institute of Industrial Science, The University of Tokyo, developed a tumor-microvessel  on-a-chip system and demonstrated that clusters of circulating tumor cells, after detaching from primary tumors, disrupt blood-vessel walls by inducing endothelial-to-mesenchymal transition. The clusters then enter the bloodstream and establish distal metastases. Targeting the ability of these clusters to disperse could help treat patients with advanced metastatic cancer.

What if we could supply 85% of Japan’s electricity needs using infrastructure that already exists? Rooftop solar panels and electric vehicle batteries are the dynamic duo proposed by a new study.

Bone-destructive diseases often arise from overactive osteoclasts, driven by the RANK-TRAF6 signaling pathway. However, treatments targeting this pathway also affect other biological processes. Now, researchers from Japan have developed a new tetravalent peptide, CR4-WHD-tet, that fine-tunes this pathway. CR4-WHD-tet selectively inhibits signals important for late-stage osteoclast maturation without disrupting the pathway’s other essential functions. This innovative approach could lead to targeted therapies with reduced side effects for osteoporosis and similar diseases.

Ultrastructural studies of centipede and other myriapod ovaries reveal direct soma-germline contact across the basement membrane, a structure typically regarded as a cellular barrier. These findings suggest a previously unrecognized form of interaction between somatic and germ cells in animals, challenging established views in zoology and cell biology.
