A research group at Osaka Metropolitan University has discovered that 2,5-distyrylpyrazine (DSP) crystals undergo a unique photoreaction. Normally, photoreactive color changes proceed uniformly throughout photomechanical molecular crystals, so that all parts of each crystal change color at the same time. However, when light shines evenly on a DSP crystal, the photoreaction propagates from edge to center, deviating from conventional photochemistry models. The group found that this phenomenon was caused by a surface effect and a cooperative effect, which make reactivity extremely high for molecules at the crystal’s edge and those adjacent to molecules that have already changed color.

Osaka Metropolitan University researchers introduced seven proteins, thought to let bacteria swim by switching the direction that their helical bodies spiral, into a strain of synthetic bacterium with minimal genetic information. As a result, they confirmed that the synthetic bacterium named syn3, which is normally spherical, formed a helix that could swim by spiraling. Further investigation revealed that only two of these newly added proteins were required to make syn3 capable of minimal swimming. This swimming synthetic bacterium can be said to be the smallest mobile lifeform genetically, as it contains the fewest number of genes.

Using a quantum computer, Osaka Metropolitan University researchers utilized quantum logic circuits to directly calculate, in a single calculation, the energy difference between two molecular geometries. The developed method was then applied to execute the molecular geometry optimization of typical molecular systems. On a classical computer, calculations based on the finite difference method require at least two evaluations of the energy for one-dimensional systems, but previous research has shown that a quantum computer can be used to calculate the energy derivatives based on this method in a single calculation. However, quantum circuits relevant to quantum algorithms capable of performing the energy derivative calculations had not been implemented. The research group has successfully created a quantum circuit to calculate the energy derivatives by modifying the quantum circuit used in the previously developed quantum phase difference estimation algorithm.

A Hong Kong Baptist University (HKBU) collaborative research team has synthesised a nanoparticle named TRZD that can perform the dual function of diagnosing and treating glioma in the brain. It emits persistent luminescence for the diagnostic imaging of glioma tissues in vivo and inhibits the growth of tumour cells by aiding the targeted delivery of chemotherapy drugs. The nanoparticle offers hope for the early diagnosis and treatment of glioma, especially cerebellar glioma, which is even harder to detect and cure with existing methods.

We don’t know much about the Earth’s inner core because recreating its conditions in a laboratory setting remains fraught with difficulties. Based on tracking seismic waves, scientists theorize that the area in and around the core comprises mostly of iron. But the values extracted from these indicators differ from how pure iron typically behaves. Now, a collaborative research group has succeeded, for the first time, in measuring the speed of sound of pure iron under pressures similar to the Earth’s inner core boundary.

A research group at the Osaka Metropolitan University Graduate School of Science has revealed a new system that allows them to control the behavior of the nematode worm Caenorhabditis elegans, using two different animal opsins, a type of light-sensitive protein. The first opsin was expressed in the worms’ sensory cells responsible for triggering avoidance behavior, making the worms move. This opsin was found to be approximately 7,000 times more sensitive to white light than the commonly used optogenetic protein channelrhodopsin-2. Likewise, a UV-sensitive opsin was expressed in the worms’ motor neurons, causing the worms to stop when exposed to UV light and start moving again when exposed to green light. Both opsins tested can be switched on and off repeatedly without breaking down, making them robust tools for future research, including the field of drug discovery.

Researchers led by Osaka University have shown that a molecule known as ATAD3A is essential for the movement of genetic material inside cellular substructures called mitochondria. Appropriate distribution of this DNA, organized into “nucleoid” structures, is key for the generation of energy by the “respiratory chain” protein complex. This study opens up opportunities for developing new methods to alter nucleoid movement and affect mitochondrial function, thereby providing potential therapies against mitochondrial diseases.

Researchers from SANKEN (The Institute of Scientific and Industrial Research) at Osaka University have genetically engineered a protein to emit the shortest-wavelength fluorescence light reported to date. They did this by optimizing the interactions between the fluorescence center (chromophore) and its surroundings, in a manner that differs from previous reports. The resulting fluorescence emission was bright and stable over a useful range of pH values. This work will aid basic and applied research, such as understanding the behavior of healthy and diseased cells.
