Researchers from the Osaka Metropolitan University Graduate School of Engineering have successfully developed a new technique allowing them to observe gas molecules packing into metal-organic frameworks (MOF) using infrared spectroscopy. Their innovation was to measure polarized light absorption of guest molecules in a MOF film to deduce molecule alignment using this common piece of lab equipment. This method is the first to show guest alignment and does so in real-time, while using an accessible and easily adoptable experimental setup. A short video (4 min) recreating their spectrometer modifications can be found in the Reference section.

Strokes have a debilitating effect on quality of life; the combination of cognitive and physical effects can be especially devastating. A new study from Osaka Metropolitan University Graduate School of Rehabilitation Science showed that moderate to severe hand and arm paralysis was dramatically improved with the use of robotic therapy, for chronic stroke patients with upper extremity hemiplegia in Japan, as reported in the journal Stroke.

2.5-dimensional materials promise new applications for artificial intelligence, electronics, automobiles and the energy sector.

Recent studies have demonstrated that character strengths, including a group of individual characteristics that have moral value and lead to ‘good virtues,’ play a crucial role in students’ participation in society and achievement of success. Kindness, which is a significant aspect of character strength, has been considered essential for school programmes to improve students’ mental health and foster positive well-being. As a key social context, schools influence students’ academic, psychological, and social well-being, providing mastery of knowledge and shaping their whole-person development. Numerous studies have highlighted the social aspects of school functions and recognised the effects of schooling on students’ academic and psychological outcomes.

A Hong Kong Baptist University (HKBU) collaborative research study has revealed that certain gut microbial enzymes mediate the reactivation of triclosan (TCS) from its inactive glucuronide metabolite. TCS is an antimicrobial agent commonly used in a wide range of consumer products, and it is associated with the development of colitis.

A new platform effectively sorts and clusters single cells according to their physical properties and could provide clues for understanding individual cell interactions.

Lithium-ion batteries power our everyday products, from laptops to vehicles, because of their safety, longevity, and charging speeds. Yet their production relies on rare metals such as cobalt and nickel. Now, a research group has unearthed a potential method for incorporating more common and cheaper elements as synthesizing electrode materials.

A recent infant study suggests that the visual experience in daily life contributes to the emergence of upper visual field bias for faces.

Coconut husk (CH), a solid biowaste derived from coconut, is typically used in household items, such as doormats. Recent studies have shown that CH is rich in lignocellulose, which can make for energy-related applications of CH. To this end, a global team of researchers, in a new study, make use of CH to develop self-powered energy storage and harvesting devices, achieving high energy density and output performance, and opening doors to a circular economy.

Scientists discovered that intramuscular fat levels are indicative of heart health. Measurements of intramuscular fat in 93 heart failure patients’ thighs showed patients with high intramuscular fat levels were at greater risk of rehospitalisation, despite no significant differences in conventional heart health criteria. These findings enable new approaches for treating heart failure, a growing concern in Japan’s ageing society.

Scientists at Daegu Gyeongbuk Institute of Science and Technology (DGIST) in Korea have fabricated a flexible material that lights up brightly when stretched and/or when an electric field is applied. The results were published in the journal Applied Physics Reviews and show promise for the development of bright, sustainable, stretchable devices for use, for example, as interactive skin displays and in soft robotics.

In a global first, scientists have demonstrated that molecular robots are able to accomplish cargo delivery by employing a strategy of swarming, achieving a transport efficiency five times greater than that of single robots.

In disaster mitigation planning for future large earthquakes, seismic ground motion predictions are a crucial part of early warning systems. The way the ground moves depends on how the soil layers amplify the seismic waves (described in a mathematical site “amplification factor”). However, geophysical explorations to understand soil conditions are costly, limiting characterization of site amplification factors to date. Using data on microtremors in Japan, a neural network model can estimate site-specific responses to earthquakes based on subsurface soil conditions.

Exercising during pregnancy bestows a wealth of benefits upon a child. New research suggests that exercise may also help reduce the offspring’s chances of getting type 2 diabetes. Researchers uncovered how SOD3, a key protein released by the placenta after exercise, improves the metabolic health of offspring and negates the impacts of maternal obesity and poor diets.

Osaka City University* study suggests memories are formed through an integration across brain regions via burst activity in amygdala-prefrontal neuronal ensembles during memory acquisition, and then hippocampal-prefrontal synchrony during post-experience sleep. (Osaka City University has now changed its name as Osaka Metropolitan University)

• Effects of gestational bisphenol A exposure were compared between rat dams and their offspring. • Bisphenol A affected the dams' circadian rhythm, immune response, and insulin resistance. • Nevertheless, at the multi-omics levels (transcriptome and lipidome), the impact on the dams was less than on their offspring. • Multi-variates analysis successfully differentiated the multi-omics effects between dams and their offspring.
