An Osaka Metropolitan University-led research team improved the AI recognition accuracy of word-level sign language recognition by adding data such as the signer’s hand and facial expressions, as well as skeletal information on the position of the hands relative to the body.

Depression continues to grapple a large proportion of the population. Given the side effects associated with the long-term use of conventional antidepressants, there is a need for novel rapid acting therapeutics with minimal side effects. Researchers from Tokyo University of Science have previously demonstrated antidepressant-like effects of delta opioid receptor agonists in rodents. In their latest study, they uncover the molecular and cellular mechanism underlying its action that can advance its therapeutic development.

Carbon fiber-reinforced polymers (CFRPs) are used in the aerospace, automotive, and sports equipment industries. However, their recycling remains a major problem. In a recent study, researchers from Waseda University demonstrated a novel direct discharge electrical pulse method for the efficient, effective, and environmentally friendly separation of CFRPs to recover high-quality carbon fibers. This work is expected to pave the way for a more sustainable world.

An Osaka Metropolitan University researcher conducted a survey on the use of private wells during the 2018 Western Japan floods in Kure City, Hiroshima Prefecture, which was affected by water supply disruptions.

Javelins were at the center of an exhibition at the Prince Chichibu Memorial Sport Museum and Library in the National Stadium, Tokyo. The title of the exhibition, which was open from January to March this year, can be translated as “The science of athletic equipment: the quest for well-flying javelins.” Its impetus was when Professor MAEDA Masato of Kobe University’s Graduate School of Human Development and Environment, who specializes in sports biomechanics and sports technology theory, donated his collection of 120 javelins to the museum. And with the Paris Summer Olympics coming up this year, where Japanese javelin throwers are expected to perform very well, we asked Maeda, who has studied the javelin, about his research and the appeal of the sport.

The Department of Orthopaedic Surgery at Kobe University Hospital is nationally known for its sports medicine. They support professional baseball, football, rugby, and other sports teams, accompanying them to games and camps. They are athletes’ last resort for recovering from injuries and also provide a variety of support services, such as health screenings, to junior high, high school, and university students. What is their role as a group of medical specialists and how do they contribute to the community? We asked KURODA Ryosuke, professor at and the chairman of the Department of Orthopaedic Surgery at the Graduate School of Medicine.

Researchers developed a novel method combining hydrogel-coated microfluidic devices with high-density microelectrode arrays to study neuronal networks. This innovation allows precise spatial and temporal recording of neural activities, advancing understanding of brain functionality. A multi-university consortium now explores biologically inspired neuronal network models for predictive coding applications.

Minocycline prevents age-related cognitive decline: Discovery focusing on the Rp58 gene

Electric devices and vehicles offer a sustainable and economical alternative to fuel-driven machines. However, concerns about the safety and longevity of conventional lithium ion batteries (LIBs) persist. A study from Doshisha University aimed to develop a novel flame-retardant quasi-solid-state battery by combining solid and liquid electrolytes. With higher safety and durability and improved performance, the new LIB has the potential to transform the applications of electric vehicles and devices.
