Hydrogen may be a clean fuel, but not all hydrogen is green. Most H₂ is still produced from fossil fuels, while storing and transporting it remain costly and technically challenging. For hydrogen to truly live up to its green promise, we need cleaner and less costly ways to produce and store it. Looking for a more sustainable way forward, researchers at Tohoku University have developed a potential solution. Their new recyclable system uses baker’s yeast to store hydrogen directly in organic molecules and abundant, inexpensive iron ions to release it when needed.

Feeding bacteria a cheap agricultural by-product enables the production of high-value biomaterials with promising biomedical and industrial applications.

Researchers from the University of Osaka, Gunma University and Kyushu University created lipid mimic molecules that form “island”-like groups called lipid domains in artificial lipid membranes. The domains are thermally stable because the propellor-shaped moiety of the lipid mimic molecules interlock and the surrounding lipids fit into the spaces between. This new method of forming domains may allow artificial lipid membrane materials to be created for catalysis, capturing molecules, and drug delivery.

Professor Yutaka Amao’s review gives a comprehensive overview of natural photosynthesis, the principles and history of artificial photosynthesis research, and carbon dioxide capture, utilization, and storage technologies.

Researchers from The University of Osaka have developed a mouse model for achondroplasia. The model identified the importance of a signaling molecule called FGFR3 and a pathway called CREB in regulating bone growth. This pathway is also at least partially responsible for the pathology associated with achondroplasia and impaired bone growth. Their findings advance our understanding of the process of bone growth and provide novel therapeutic targets for achondroplasia.

A collaborative team of four professors and several graduate students from the Departments of Chemistry and Biochemical Science and Technology at National Taiwan University, together with the Department of Applied Chemistry at National Chi Nan University, has achieved a long-sought breakthrough. By combining atomic force microscopy (AFM) with a Hadamard product–based image reconstruction algorithm, the researchers successfully visualized, for the first time, the nanoscopic dynamics of membrane rafts in live cells—making visible what had long remained invisible on the cell membrane.

A new regional assessment shows that Southeast Asia is a major net source of greenhouse gases, with land-use change and rising fossil fuel use overwhelming natural carbon sinks, reservoirs that store carbon-containing chemical compounds for a long period.

Surface-bound gels may have provided the structure and chemistry for life to take root on Earth, and perhaps beyond

Researchers from The University of Osaka fabricated a nanopore surrounded by a gate as a cooling system with enhanced efficiency for semiconductor chips. Applying a voltage to the gate induces the flow of ions through the nanopore. Creating a salt gradient makes the ion flow unidirectional. Heat is dragged along with the ions, resulting in heat transfer. Changing the applied voltage from negative to positive switches the system from cooling to heating.

Researchers at The University of Osaka and The University of Tokyo developed a photoactivatable alkyne tag that enables stable, selective visualization of biomolecules inside living cells. The technology would contribute to reveal previously unseen molecular communication, paving the way for advances in cell biology and drug discovery.

A metal-free organic liquid has been developed that phosphoresces at room temperature. Rapid phosphorescence endows the liquid with the highest phosphorescence efficiency in air among organic liquids. The new molecule has a 3-bromo-2-thienyl diketone backbone with attached dimethylocylsilyl (DMOS) groups. Attaching one DMOS group liquefies the backbone, whereas attaching two DMOS groups prevents molecular aggregation, which typically weakens phosphorescence. This new, flexible liquid can be applied to develop flexible electronic devices.

A customizable protein has been developed to help the body remove harmful cells, such as those involved in cancer or autoimmune diseases, offering a potential new direction for treatments.

To reduce plastic pollution and promote environmental sustainability, scholars from the Lingnan University School of Interdisciplinary Studies and their research team have developed a successful new eco-friendly bioplastic material. Unlike conventional plastics, it degrades naturally into harmless water and carbon dioxide in as little as 29 days under ambient conditions, and is a practical way to mitigate global plastic pollution. Their study, “Sustainable DNA-polysaccharide hydrogels as recyclable bioplastics”, was recently published in the respected journal Nature Communications.

A surgeon can excise breast cancer from the body, but even the most skilled scalpel may not be able to remove every cell — especially when the cells have spread from the original disease site elsewhere in the body. This proliferation and migration of breast cancer cells involves many still unknown molecular means, but researchers at Hiroshima University have elucidated at least one mechanism, involving protein receptors that bind to one another. With the discovery, they may have also uncovered how short chains of protein building blocks could serve as a novel anticancer drug.
