Researchers discover tightest arrangement of bilayer alkali metals between graphene layers
Researchers at AIST, in collaboration with Osaka University, Tokyo Polytechnic University, Kyushu University, and National Tsing Hua University, have developed a technique to insert alkali metals into the interlayers of graphene, which is a single layer of carbon atoms arranged in a hexagonal lattice. They have succeeded in directly observing the atomic arrangement of the inserted alkali metal atoms which is a hexagonal close packed bilayer structure.

Not just a lodger: Novel host-guest assembly provides enhanced reactivity
By design, synthetic molecules typically have specific jobs to prevent or accelerate reactions between other molecules. To help control more complicated reactions, researchers may harness spare space in one molecule to synthesize another chemical structure. The host-guest assembly can better induce the specific desired reaction than either component individually—if the scientists designing the assembly get it right.

In vivo production of CAR-T cells using virus-mimetic fusogenic nanovesicles
Chimeric antigen receptors (CARs) are synthesized membrane proteins that enable lymphocytes to recognize and respond to the specific antigens of target cells. Despite the impressive efficacy of CAR-T cell therapy in treating B-cell lymphoma or leukemia, the expensive and complex manufacturing process has hindered its widespread clinical application.

Printed polymer allows researchers to explore chirality and spin interactions at room temperature
A printable organic polymer that assembles into chiral structures when printed has enabled researchers to reliably measure the amount of charge produced in spin-to-charge conversion within a spintronic material at room temperature. The polymer's tunable qualities and versatility make it desirable not only for less expensive, environmentally friendly, printable electronic applications, but also for use in understanding chirality and spin interactions more generally.

Driving photochemistry with sub-molecular precision
Absorption of light initiates many natural and artificial chemical processes, for example, photosynthesis in plants, human vision, or even 3D printing. Until now, it seemed impossible to control a light-driven chemical reaction at the atomic scale, where only a specific part of one molecule is addressed.

DNA origami-based vaccine platform enhances anti-tumor responses through nanometer-precise spacing of molecules
Therapeutic cancer vaccines are a form of immunotherapy in the making that could not only destroy cancer cells in patients, but keep a cancer from coming back and spreading. Multiple therapeutic cancer vaccines are being studied in clinical trials, but despite their promise, they are not routinely used yet by clinical oncologists to treat their patients.

New electron microscopy technique for thermal diffusion measurements
A NIMS research team has developed a technique that enables the nanoscale observation of heat propagation paths and behavior within material specimens. This was achieved using a scanning transmission electron microscope (STEM) capable of emitting a pulsed electron beam and a nanosized thermocouple—a high-precision temperature measurement device developed by NIMS. The research is published in Science Advances.

Using adavosertib-encapsulated MOFs for p53-mutated gallbladder cancer treatment via synthetic lethality
Since the revelation of poly(ADP-ribose) polymerase (PARP) inhibitors and their remarkable results in the treatment of BRCA1/2 mutant cancers, synthetic lethality (SL) in antitumor therapy has attracted increasing attention. SL is a phenomenon in which a single genetic event is insufficient to induce cell death, but multiple genetic events lead to cell death.
