Triple-negative breast cancer (TNBC) accounts for roughly 15–20% of all breast cancer cases and is difficult to treat. Patients are often left with chemotherapy as their only treatment option. This is because TNBC tumors contain a large number of T cells that suppress the immune system. Yet researchers from Tohoku University have come up with a three-pronged approach to overcome this problem.

Researchers from the University of Osaka have developed a new class of chiral semiconducting polymers that can generate highly spin-polarized electrical currents.

Kanazawa University, Japan – Research group led by Prof. Keiichi Hirano and Assistant Prof. Akira Matsumoto have developed a novel synthetic method for the selective cleavage of strong carbon–hydrogen (C–H) bonds while preserving weaker carbon–silicon (C–Si) bonds. This transformation enables the upgrading of structurally simple α-silyl alcohols into functionalized derivatives that are difficult to access by conventional methods. The key to this success lies in utilizing a finely tuned phosphonium ylide catalyst in combination with an organophotoredox catalyst under visible-light irradiation.

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.

Researchers from National Taiwan University have developed a sunlight-powered catalyst that converts carbon dioxide into methane more efficiently.

Researchers from the University of Osaka and collaborating institutions developed an autonomous solid-state nanopore that combines sensing, memory, and signal generation in a single device. Unlike conventional nanopores, the sensor continually reshapes itself through chemical reactions, producing unique electrical signatures as molecules pass through, providing a basis for memory. The device successfully identified a variety of nucleotides and amino acids, providing a new platform for molecular sensing and future iontronic computing.

Researchers developed a terbium-doped aluminum gallium nitride LED that produces blue, green, yellow, and red light from the same area at room temperature. The emission wavelengths remained highly stable as the current changed. Increasing the aluminum content improved energy transfer and efficiency, while using an aluminum nitride base layer enhanced crystal quality and device performance. With further improvements, this approach could simplify the production of full-color micro-LED displays and contribute to compact displays, wearable devices, and white-light sources.

When plastics are recycled, their strength gets weakened over time as the long molecular chains gradually break down under repeated exposure to heat and moisture. However, a research group has added a chain extender to the recycling process, allowing polymer chains to reconnect, and a plastic tensile strength to return to normal.

Graphene revolutionized materials science after its discovery in 2004. Its list of potential applications is long, but its use in high-temperature superconductors has been stymied by weak electron interactions. Researchers from Tohoku University have recently created a stable version of boron graphene on the surface of a three-dimensional crystal, potentially overcoming this limitation and opening a pathway toward more energy-efficient electronic devices.

Lithium metal is a prime contender for the next generation of rechargeable batteries. But in order to live up to that potential, scientists have had to try and find a solution to the dendrite problem. Lithium tends to grow into needle-like structures (dendrites) which reduce the battery life and create safety hazards. The answer may be like the key to most things in life: balance. Researchers from Tohoku University's Institute for Materials Research (IMR) discovered that, rather than increasing the amount of lithium salt in a battery, an optimal lithium concentration allows lithium to deposit evenly and form a stronger protective layer on the battery surface.

Yet a clever ligand design could pave the way for more efficient and durable catalysts.

Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University, Institute for Molecular Science and SOKENDAI have uncovered the hidden mechanism behind a molecular switch—a molecule that can change between different structural states in response to a chemical signal. Their study, published in the Journal of the American Chemical Society, reveals how molecules can gradually switch between alternative states, a process that could help scientists design future molecular machines, smart materials, and molecular information technologies. To make the discovery, Shigehisa Akine and colleagues created a specially designed molecular cage that changes shape unusually slowly. This allowed them to observe, for the first time, the sequence of molecular events that occurs after the molecule receives a chemical input. The study provides one of the clearest views yet of how molecular recognition triggers structural change and demonstrates that the response speed of a molecular system can itself be engineered through molecular design.
