In the same way that the number of rings in a tree can tell us its age, the characteristics of rocks such as breccia can tell us about the history of a region. The breccia around Ichinokawa Mine (located in Ehime prefecture) are of particular interest, as the mine is located south of the Median Tectonic Line. Researchers at Tohoku University uncovered how breccia can provide valuable evidence to estimate the energy of past earthquakes in the area.

In interpersonal relationships, people sometimes perceive that the other person understands them. When people feel this way, they are more willing to engage with the other person, but the reasons for this were not well understood. This study reveals that the psychological process for this feeling largely depends on a reduction in prejudice towards the other person. The results of this study may help us understand the psychological process behind reducing discrimination.

Researchers from Osaka University have used a novel combination of short-read and long-read RNA sequencing to identify the different isoforms of genes expressed in the crustacean Daphnia magna. Males and females are genetically identical, but using this technique the team revealed genes that switch the predominant isoform in a sex-dependent manner. This study contributes to our understanding of Daphnia’s sexual dimorphism and helps further advance technologies in crustacean aquaculture.

Researchers from Osaka University have found that gargling with an antiseptic mouthwash can reduce so-called ‘bad’ bacteria in the mouths of patients with type 2 diabetes. Notably, this reduction in bacteria was accompanied by improved blood-sugar control in some patients. Given that the oral diseases caused by these bacteria have been linked to many other serious inflammation-associated diseases, such as cardiovascular disease and Alzheimer’s disease, this simple treatment may have widespread effects.

Much is known about the added complication to pregnancy when it comes to the age of the mother, but recent studies show that the age of the father can also heighten the risk of neurodevelopmental disorders. A team of researchers has explored the impacts of paternal aging on microRNAs, the molecules that play a crucial role in regulating gene expression.

Osaka Metropolitan University scientists, in cooperation with researchers from the National Astronomical Observatory of Japan, have captured cosmic-ray extensive air showers with unprecedented precision using the prime-focus wide field camera mounted on the Subaru Telescope, situated atop Mauna Kea in Hawaii. Analyzing approximately 17,000 images captured between 2014 and 2020, they pinpointed 13 images containing extensive air showers, with a number of particle tracks far exceeding the usual count.

The annual burning of crop residue in India causes widespread air pollution, particularly in the northwestern regions. A group of international researchers has used low-cost yet reliable instruments to gauge the effects of air pollution in these areas, making it the first quantitative study of its kind.

Using heated tobacco product makes severe COVID-19 more likely
23 Mar 2023
A research group from Osaka Metropolitan University investigated the relationship between tobacco use, including heated tobacco products, with the risk of SARS-CoV-2 infection and severe COVID-19. The researchers administered an online survey of living conditions in February 2022 to 30,130 participants aged 16-81 years, finding that heated tobacco product users had significantly higher rates of SARS-CoV-2 infection compared to non-tobacco users. Furthermore, the research group found that among all tobacco users, those who used both heated tobacco products and traditional cigarettes had the highest incidence of requiring hospitalization or oxygen due to COVID-19.

Brain shrinkage patterns tied to low trust have links to depression vulnerability that can alert to its early detection even before symptoms appear.
More than half of patients suffer long COVID symptoms
24 Feb 2023
A research group from the Osaka Metropolitan University Graduate School of Medicine conducted a survey of 285 patients regarding the long-term aftereffects of COVID-19. As a result, they revealed that more than half of COVID-19 patients still had residual symptoms, even close to a year afterward. It became clear that fatigue, abnormalities in senses of taste and smell, hair loss, and sleep disorders could persist, regardless of the severity of the initial COVID-19.

To clarify the mechanism of serial dependence in number perception, a research team from Osaka Metropolitan University conducted two tests, independently asking subjects to estimate the number of coins, or to estimate the value of those coins, shown on-screen for half a second. The results showed that serial dependence was confirmed in both tasks and that the most significant effect on serial dependence was not caused by the last stimuli, but the subjects last response. These results indicate that higher-order cognitive processing has a greater influence on the occurrence of serial dependence.
