Researchers from Osaka University have identified a protein, FER1L5, that is essential for sperm to acquire fertilizing ability. Sperm from mice lacking this protein were unable to undergo the “acrosome reaction”, which releases molecules that facilitate fertilization, resulting in impaired male fertility. As FER1L5 is also present in human sperm, this work may lead to new diagnostic methods and treatments for male infertility in humans.

Osaka Metropolitan University scientists have succeeded in synthesizing fumaric acid, a raw material for plastics, from CO2 powered by solar energy—for the first time. Typically, fumaric acid is synthesized from petroleum as a raw material to make polybutylene succinate, a biodegradable plastic, but this research shows that it can be synthesized from CO2 and biomass-derived compounds using renewable energy.

A research group, at the Osaka Metropolitan University Graduate School of Engineering, has succeeded in measuring spin transport in a thin film of αNPD molecules—a material well-known in organic light emitting diodes—at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been used to control spin transport in the past, the thin molecular film used in this study is photoconductive, allowing spin transport control using visible light.

New research from Osaka University indicates that more screen time at age 2 is associated with poorer communication and daily living skills at age 4—but when kids also play outdoors, some of the negative effects of screen time are reduced. Increasing outdoor play time could reduce the negative effects of screen time on daily living skills by almost 20%.

Imagine if your t-shirt could take your sweat and analyze it for health abnormalities. Well, this is much closer to reality after a recent breakthrough by a research group led by a Tohoku University assistant professor. The group created the first microelectronic fiber with microscopic parameters that is capable of analyzing electrolytes and metabolites in sweat.

Controlling a material’s thermal conductivity can help insulate our homes, improve the performance of electronic devices, conserve power consumption in cars, and generate greater power efficiency. Now, a group of researchers has unveiled a novel mechanism that leads to further suppression of thermal conductivity in thermoelectric materials, something that will help develop new guidelines for producing high-performance thermoelectric materials.

In a study recently published in Cancer Science researchers from Kanazawa University show how some intestinal cancer cells lose their ability to spread as they divide and can be eliminated as the cancer grows.

Researchers led by Osaka University demonstrated the role of endothelial cell-specific protein Roundabout4 (Robo4) in the reduction of vascular permeability and mortality in mouse models of severe infection. The research team identified a drug inhibitor that increased Robo4 expression and reduced mortality in sepsis and SARS-CoV-2 mouse models of infection. These findings may aid in the development of drugs to reduce the mortality rate of severe infectious diseases.

Believed to have been built in 250 BCE to commemorate the occasion of the Buddha's first sermon in Sarnath, the lion capital is the most elaborately carved surviving capital made under the patronage of the Mauryan king Ashoka.

Understanding how dust grains form in interstellar gas could offer significant insights to astronomers and help materials scientists develop useful nanoparticles.

Asia Research News monitors the latest research news in Asia. Some highlights that caught our attention this week are the growing trend of unique name pronunciations in Japan, an aquarium that can tell you about which fish you are looking at, and which professional baseballs are slipperiest.

Magnesium hydride has long been touted for its potential to store large amounts of hydrogen, something essential if hydrogen is to play a role in powering a sustainable future. Yet, sluggish dehydrogenation kinetics and the high temperature required to decompose and produce hydrogen from the material have stymied its use. Now, researchers have identified why this is so, paving the way for future design guidelines and widespread commercial use.

A team including Kavli IPMU has studied the relation between galaxy size and luminosity of some of the earliest galaxies in the universe taken by the James Webb Space Telescope, less than a billion years after the Big Bang.

Professor Keith Ho Wing-Kei at the Department of Science and Environmental Studies, The Education University of Hong Kong, has been recognised as a 2022 Highly Cited Researcher by Clarivate Analytics. This is the fifth consecutive year he has been named in the list.

Osaka Metropolitan University scientists delved into the relationship between gait function and knee extension velocity after total knee arthroplasty and compared the effects of various factors on walking. The results reveal that knee extension velocity, measured while seated, on the operated side was the most important determinant of gait function. These findings are expected to contribute to the development of new rehabilitation programs for efficient gait function improvement.

An Osaka Metropolitan University research group recorded the autonomic nervous system activity in patients with irritable bowel syndrome (IBS) and healthy subjects using a wearable device and a proprietary smartphone application to record daily life events such as defecation and sleep. As a result, they found that sympathetic nervous system activity was activated in IBS patients from 2 minutes before defecation and continued until 9 minutes after defecation. Further research is expected to improve the quality of life of IBS patients and elucidate the pathophysiology.

A team of Japanese researchers created a high-quality genome assembly of red perilla, a step toward harnessing the plant’s potentially useful bioactive chemicals — and its medicinal properties.

An Osaka Metropolitan University research team analyzed the regulatory mechanisms of carbohydrate-hydrolyzing enzyme production in Aspergillus aculeatus, a filamentous fungus that produces enzymes with an excellent ability to degrade plant biomass. The team found that UDP-glucose 4-epimerase (Uge5), an enzyme known for its involvement in galactose metabolism, also regulates the expression of degrading enzyme genes in A. aculeatus. This is the very first report of Uge5’s roles in selective gene expression in response to different types of inducing sugars in filamentous fungi.

A research team led by Osaka Metropolitan University has revealed a difference in neural activity in response to visual food stimuli, depending on whether those stimuli are presented consciously or unconsciously. Using a questionnaire to assess the study participants, the team found that this difference was associated with their scores on eating behaviors, including emotional eating and cognitive restraint of food intake. These results indicate that eating behavior cannot be understood without taking into account both unconscious and conscious neural processes.
