Researchers led by Osaka University report the development of INCIDER, a fluorescent sensor system that enables high-contrast microscopic imaging of temporal changes in cellular interactions mediated by the N-cadherin molecule. This sensor system, which emits much brighter fluorescence than the currently used system while detecting these interactions, is expected to have a wide range of applications in developmental biology, neuroscience, and other fields.

Using cryogenic electron microscopy, a research team from the Research Center for Artificial Photosynthesis (ReCAP) at Osaka Metropolitan University has revealed, for the first time, the structures and binding environments of pigments bound to a protein called a photosynthetic antenna of the marine green macroalga Codium fragile. The team’s results extend our knowledge about the molecular mechanism by which blue-green light—the only light available in deep seawater—is efficiently utilized for photosynthesis.

Researchers led by Osaka University generated a time-stamping method to trace the development and survival of plasma cells in the bone marrow and spleen. Using a mouse model in which plasma cells were fluorescently labeled in an inducible manner, they found that plasma cells were continuously replenished by new cells, a small portion of which differentiated into long-lived plasma cells (LLPCs). These findings may aid in the development of new vaccines that efficiently induce LLPCs.

Confounding color changing crystal!
13 Dec 2022
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 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.

A research team at Osaka Metropolitan University has developed a microelectromechanical system (MEMS) piezoelectric vibration energy harvester, which is only about 2 cm in diameter with a U-shaped metal vibration amplification component. The device allows for an increase of approximately 90 times in the power generation performance from impulsive vibration. Since the power generation performance can be improved without increasing the device size, the technology is expected to generate power to drive small wearable devices from non-steady vibrations, such as walking motion.

Hesitancy in helping

An Osaka Metropolitan University study found that differences in culture affect when Japanese and American university students feel comfortable providing social support. The researchers found that Japanese university students were less likely than American students to offer assistance to a close friend or family member unless they had been explicitly asked for help, even when they knew that the person needed assistance. There were no differences in providing assistance between Japanese and American students when requests for help were explicitly stated.

The research team investigated the role of D-amino acids in severe viral infection. Mouse models of influenza A and COVID-19 infection and patients with severe COVID-19 demonstrated reduced D-amino acid levels in the blood. Supplementation with D-alanine mitigated body weight reduction in IAV model mice and improved survival in COVID-19 model mice. D-amino acids may represent potential biomarkers and therapeutic agents for the treatment of severe viral infection.
