Unseen Threat Compromises Future of Marine Apex Predator

A team from Osaka University has developed scSPOT, a new technique that reveals how immune cells called Tregs simultaneously control the immune system. The team identified key immune cells controlled by Tregs and found that Tregs are targets for the cancer drugs ipilimumab and tazemetostat. They also found that Tregs are indicators of serious viral infection. This valuable technique may accelerate the development of treatments for cancer and other diseases.

Gate-controllable TMD spin valves enable ultralow power, high-speed operation, offering efficient read/write performance for spintronic memory.

Because of climate change, harmful algal blooms are increasing in frequency and intensity. New science helps demystify the frequent harmful algal blooms in the Pacific off the coast of Chile by studying how algae species interact with each other and their environment.

AI transformational impact is well under way. But as AI technologies develop, so too does their power consumption. Now, researchershave developed a new spintronic device that can potentially revolutionize AI hardware through higher efficiency and lower energy costs.

Kavli IPMU researchers are part of an international team that has found dark matter dominating the halos of two supermassive black holes 13 billion light years away.

A hedonic price model incorporating street view images processed by machine learning and existing property data achieves nearly 75% accuracy for rent prediction in Osaka City

Researchers created platinum-mixed metallic magnetic nanofilms that are 5x more efficient – the ultimate energy-saving solution.

A collaboration led by researchers at Osaka University has developed a versatile platform with an electrically controlled nanogate that can be used for applications in sensing, chemical synthesis, memristors, and neuromorphic computing. The nanogate, which consists of a pore in a membrane, is closed by the formation of a precipitate and opened by the dissolution of the precipitate, which are regulated by the applied voltage.

What created the Noto Peninsula landscape we know today? After examining the devastation from the 2024 Noto Peninsula earthquake, researchers from Tohoku University have a theory.

Researchers at Osaka University developed advanced terahertz photodetectors containing ‘living’ microelectrodes. A vanadium dioxide (VO2) layer was precisely deposited on a silicon substrate. Temperature regulation modulated the size of conductive metallic areas in VO2, forming a dynamic microelectrode network that selectively enhanced the response of the silicon substrate to terahertz light. These advanced photodetectors reveal the potential of modifiable metamaterials such as VO2 to overcome the performance limitations of traditional materials.

Detailed study of a Greenland glacier’s flow rate reveals the impact of environmental conditions.

Researchers from Japan find that certain antioxidant enzymes, called selenoproteins, significantly contribute to fighting cell aging. The team used a gene knockout mouse model to help them study the effects of disrupting selenoprotein synthesis. This knockout negatively impacted hematopoietic stem cells and B cell-lineage immune cells, which was driven by the lack of selenoprotein-mediated fighting of lipid peroxides. These phenotypes mimic what is observed in age-related diseases, emphasizing the importance of selenoproteins in these disorders.

In a study on public psychology with regard to the COVID-19 pandemic, researchers from Osaka University found no significant differences among regions of Japan regarding either risk perception or infection-prevention behaviors during the “state of emergency,” suggesting spillover effects between targeted and non-targeted regions. However, risk perception diminished after restrictions were lifted, and both risk perception and hygienic behaviors saw further reductions after the downgrading of the legal status of COVID-19 to that of a common seasonal flu.
