Charge-recharge cycling of lithium-superrich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements.

Osaka University researchers discovered a concerning association between bacteremia and probiotic use, particularly with Clostridium butyricum (C. butyricum) MIYAIRI 588. Whole-genome sequencing revealed that all C. butyricum bacteremia strains were probiotic derivatives. Out of 6,576 cases of positive blood cultures, C. butyricum was detected in only five cases, all derived from probiotics. The study underscores rare but serious adverse events linked to probiotics, advocating cautious prescribing practices, especially for hospitalized patients.

Researchers from Osaka University have found that a brain disorder associated with flu (influenza-associated encephalopathy, or IAE) can be caused by the influenza virus entering the brain from the blood via endothelial cells. In these cells, the researchers observed viral protein accumulation, suggesting that antivirals targeting viral transcription/translation may be useful treatments for some patients. Given the lack of effective treatments for IAE, this finding will likely improve patient care and reduce IAE-related deaths worldwide.

Samples reveal evidence of changes experienced by the surface of asteroid Ryugu, some probably due to micrometeoroid bombardment.

Our brains are truly miraculous. They can process vast swathes of information with very little energy supply. One of the many ways our brain may do this is through dilation of blood vessels, which enhances energy circulation and clears wasteful materials. A research team has recently developed a method that easily observes and monitors this phenomenon.

Chemical and heat treatment of sewage sludge can recover phosphorus in a process that could help address the problem of diminishing supplies of phosphorus ores.

Osaka University researchers discovered liver resident macrophages' pivotal role in defending against gut bacteria and related substances entering via the portal vein, particularly under compromised intestinal barrier conditions. Identified as "sentinel macrophages," they are activated by isoallo-lithocholic acid. This finding holds promise for developing preventive and therapeutic strategies for liver chronic inflammatory diseases, such as metabolic dysfunction-associated steatohepatitis (MASH), by enhancing the function of these macrophages to mitigate inflammation and improve treatment efficacy.

As wildfires in Siberia become more common, global climate modeling estimates significant impacts on climate, air quality, health, and economies in East Asia and across the northern hemisphere.

The enzyme PI3K plays a critical role in cell migration. Scientists have long understood this function. But researchers have recently unveiled that a subunit of this enzyme also has the ability to slam on the breaks to this process.

Researchers from Osaka University examined how specific types of contextual changes, such as government recommendations and perceived behavior of others, influenced mask-wearing behavior during the COVID-19 pandemic. They found a complex relationship between societal norms and individual behavior during the pandemic, indicating that future strategies for public health crises interventions should consider various factors and contexts, including cultural predispositions.

Using neutron scattering and voltage measurements, a group of researchers have discovered that a material's magnetic properties can predict spin current changes with temperature. The finding is a major breakthrough in the field of spintronics.

Bacteriophage therapy could be developed based on study’s results

When epileptic patients suffer seizures, their brain is undergoing repetitive and excessive neuronal firing. But what triggers this has stumped scientists for years. Now, researchers have used fluorescence calcium sensors to track astrocytes' role in epileptic seizures, finding that that astrocyte activity starts approximately 20 seconds before the onset of epileptic neuronal hyperactivity.

Electron spin states can now be probed at much higher resolution and more efficiently, opening new opportunities in materials analysis and data processing technologies.

Researchers at Tohoku University and the University of California, Santa Barbara have unveiled a probabilistic computer prototype. Manufacturable with a near-future technology, the prototype combines a complementary metal-oxide semiconductor (CMOS) circuit with a limited number of stochastic nanomagnets, creating a heterogeneous probabilistic computer.

Researchers from Osaka University used structured light and switchable fluorescent molecules to reduce the background light from the out-of-plane regions of microscope samples. This method allowed for the acquisition of images that surpassed the conventional resolution limit, and it may be useful for further study of cell clusters and other biological systems.

A recent study by Tohoku University researchers has shed light on the association between dairy product consumption and odd-number carbon chain fatty acids (odd-FA) within the Japanese population, a correlation previously confirmed in Europe and Oceania but understudied in Asian countries.

Researchers from Osaka University found that a new activator called L687 induces cancer cells to accept delivery of antisense oligonucleotide (ASO) drugs. These drugs can treat cancer by blocking the transfer of messages from genes that encourage cancer growth. Previous methods to deliver ASOs into cells had only limited success. This research will help accelerate the development and delivery of novel ASO cancer therapies.

Researchers from Osaka University and collaborating partners have synthesized triarylborane (TAB) compounds that exhibit unusual optical responses upon binding to certain anions. They also synthesized thin polymer films that incorporate the TAB and retain the sensing as well as the light emission properties of the TAB. This work is an important advance in plastic research and has applications in analyte sensing as well as electronic display technologies.
