For decades, scientists have understood proteins primarily through two defining features: their amino acid sequence and their three-dimensional structure. This framework has driven major advances in biology, biotechnology, and medicine, culminating in recent artificial intelligence tools capable of predicting protein structures with remarkable accuracy. Yet a fundamental challenge remains: even when a protein's sequence and structure are known, predicting its function, interactions, and behavior often remains difficult. An international team of researchers from Japan, Finland, Italy, and the United States now reports evidence that part of this missing information may lie in an often-overlooked component of proteins: the highly organized water surrounding them. In a study accepted for publication in Nature Communications, the team provides the first direct three-dimensional visualization of sequence-dependent hydration architectures surrounding peptide assemblies at sub-nanometer resolution using advanced three-dimensional atomic force microscopy (3D-AFM). The findings reveal that water near peptide and protein surfaces is not simply a passive solvent. Instead, it forms highly organized, multilayered structures whose organization is dictated by the underlying amino acid sequence and surface chemistry. These hydration architectures extend multiple layers from the peptide surface and contain distinct structural signatures associated with hydrophobic, polar, aromatic, and charged amino acid residues. 

It’s a fish-eat-fish world out there. A new model by researchers at Tohoku University’s WPI-AIMEC and JAMSTEC may help us better understand these complex ocean relationships. Don’t forget: this food chain involves us too!

Fluorescent protein imaging is an indispensable tool in life science research, enabling visualization of protein movement and localization, gene expression, signaling pathways, protein-protein interactions, and more. For simultaneous analysis of multiple proteins (i.e. multiplex imaging), a variety of fluorescent proteins that emit different colors (blue, green, yellow, and red) have been developed. However, the number of colors that can be distinguished simultaneously is limited, making it difficult to observe and distinguish multiple fluorescent proteins that emit similar colors. Now, researchers from WPI-ITbM at Nagoya University have demonstrated that overlapping colored fluorescent proteins can be distinguished within living plant cells using fluorescence lifetime imaging microscopy (FLIM). This research was published in Plant Physiology on July 30, 2026.

Summary

Familial Mediterranean fever (FMF) is a genetic autoinflammatory disorder that causes recurrent fevers and painful inflammation of the abdomen, chest, and joints. The disease is caused by mutations in MEFV, the gene that encodes a protein called pyrin. Yet for nearly three decades, the key step that allows pyrin to activate the inflammatory switch has remained a mystery.

Two new companion studies published in Science Immunology by researchers at Kyoto University and their collaborators now shed light on this long-standing question. Approaching the question from opposite directions—one starting from a small group of patients with severe unexplained inflammation, the other from a systematic functional analysis of 265 mutations in MEFV drawn from genomic databases—the studies converge on the same molecular mechanism. They reveal that a lock-and-key interaction between pyrin and a small cellular regulator called CDC42 acts as the switch that ignites inflammation.

These findings clarify the missing step in pyrin activation and open the way to more accurate diagnosis and personalized treatment for patients living with diseases driven by dysregulated pyrin activity.

The two studies will be published in Science Immunology at 14:00 ET on August 7, 2026 (03:00 JST on August 8, 2026).

Researchers have achieved the world’s first demonstration of a gate-defined quantum dot in zinc oxide (ZnO), a material prized for qubit applications. Beyond confirming controlled single-electron behavior, the devices showed an unconventional Kondo effect appearing regardless of electron number—a surprising signature of ZnO’s strong electron correlations and a new platform for quantum technology research.

Discovering the materials needed for cleaner energy technologies has long been a slow process - but AI could change that. Researchers at Tohoku University have developed a closed-loop AI framework that continuously learns from experiments to identify promising energy materials faster and at lower cost. The approach could accelerate the development of next-generation batteries, hydrogen storage and other low-carbon technologies. 

Controlling interactions between molecules and their functions from the molecular level to the macroscopic scale is challenging in supramolecular chemistry and materials chemistry. To this end, a research team led by Associate Professor Yosuke Tani from WPI-ITbM at Nagoya University and Keisuke Wada from Kyoto University designed a vapor-controlled reversible host–guest chemistry system that controls the optical and physical properties of a functional molecular liquid (FML)—non-volatile fluids that can feature optical, electronic, and catalytic properties. Their research was published in Chemical Science on July 21, 2026.
