Researchers analyze bone marrow-derived and peripheral blood-derived fibrin clots showing that the former contains more growth factors. They then show that bone marrow-derived fibrin clots can be used for meniscus suturing, even in the inner-most avascular regions, and with a 2-year post-operative follow-up, they show bone marrow-derived fibrin clots support healing better than their peripheral blood counterparts.

Scientists show that an ocean-bottom seismometer deployed close to the calving front of a glacier in Greenland can detect continuous seismic radiation from a glacier sliding, reminiscent of a slow earthquake.

Researchers from The University of Tokyo Institute of Industrial Science and Fudan University experimentally interrogate a phenomenon that bridges diverse fields of science and engineering

Japanese and Zambian scientists have shown that environmental lead poisoning in children affects not only their own health and wellbeing, but the vitality and mental health of their mothers, as well.

Assistant Professor Mai Ishihara is the first female full-time researcher at Hokkaido University’s Center for Ainu and Indigenous Studies (CAIS) and is the first female faculty member who openly reveals her Ainu ancestry. As a quarter-Ainu, Ishihara talked about how she had been subdued by her own ignorance, and later by silence, of her Ainu ancestry. She transformed her struggle and her views on the pain faced by her Ainu (indigenous people of Hokkaido) ancestors into a book based on her long-term research.

A new non-invasive technique scans “chemical fingerprints” to see if ordinary cells’ reprogramming into stem cells is on track and verify transformation success by matching “print” patterns.

Using only pen and paper, Kavli IPMU PI Hitoshi Murayama has found theoretical proof of a decades-old claim that Quantum Chromo Dynamics leads to light-weight pions.

Researchers from Osaka City University find that when the larva nematode C. elegans is fed a diet of Bacillus subtilis var. natto, a bacteria used to ferment soy beans into the traditional Japanese food natto, upon reaching adulthood these worms are able to survive infections from the gram-positive bacteria Staphylococcus aureus and Enterococcus faecalis longer than when fed a standard diet of non-pathogenic E. coli.

By virtually reproducing physical reservoir computing, a new information processing technology, using numerical simulation, the present study reveals that vortices in fluid flow phenomena in the downstream region of a cylinder are the key to information processing capability. It is expected that this result concerning fluid flow vortices and information processing capability will be useful in enhancing the information processing capability of the physical reservoir using fluid flow.

Researchers at Osaka Prefecture University have established an approach to identify the orientation of molecules and chemical bonds in crystalline organic-inorganic hybrid thin films deposited on substrates using Fourier transform infrared spectroscopy (FT-IR) and polarized infrared light with a 3D-printed attenuated total reflectance (ATR) unit. This inexpensive method with laboratory-grade equipment quickly reaches the crystal-structure model of even extremely thin films of less than 10 nm.

Researchers from The University of Tokyo Institute of Industrial Science develop a flood forecasting system that could help protect people and property during typhoons

Researchers from Hiroshima University now have a better understanding of the mechanism underlying how certain bacteria can transfer genetic material across taxonomic kingdoms, including to fungi and protists. Their work, published in Frontiers in Microbiology, could have applications in changing how bacteria perform certain functions or react to changes in their environment.

Researchers from The University of Tokyo Institute of Industrial Science report colloidal spheres that can be used to determine the rotational dynamics of dense suspensions

A team of scientists has shown that the healing of skin blisters is driven by hair follicle stem cells, which delay their own development in the process.

Hokkaido University researchers have developed a simple method that converts existing generic polymers into luminescent polymers using mechanical force.

Publication bias, or the tendency of researchers and journals to not publish uninteresting findings, plagues much of the natural sciences and especially biomedical research. Hiroshima University researchers have developed a meta-analytic technique exploiting publicly available transcriptome databases that avoids the problem—and in so doing, discovered four genes previously unknown to be associated with responding to low-oxygen stress.

Chemical rings of carbon and hydrogen atoms curve to form relatively stable structures capable of conducting electricity and more — but how do these curved systems change when new components are introduced? Researchers based in Japan found that, with just a few sub-atomic additions, the properties can pivot to vary system states and behaviors, as demonstrated through a new synthesized chemical compound.

The chances of restoring fertility through sperm stem cell transplant are as random as a coin toss. But a team of scientists developed a new strategy that serves as a “weighted coin” that can favorably rig the odds to achieve outcomes where fertility is successfully restored.

No one knows what happened in the Universe for its first 400,000 years, but a new paper suggests discovering the hypothetical particle axion could shed light on the early history of the Universe. What's more, current dark matter experiments may have already detected it in its data.

Coral insights into 1,000 years of seasonal changes in the Arabian Sea warn of significant impacts caused by global warming.

Scientists have found a way to make hydrogen move faster through a solid material at cooler temperatures, paving the way for more sustainable and practical energy storage devices.

Scientists have uncovered a summertime climate pattern in and around the Arctic that could drive co-occurrences of European heatwaves and large-scale wildfires with air pollution over Siberia and subpolar North America.

Researchers from the Institute of Industrial Science at The University of Tokyo, Kobe Steel, Ltd, and Kobelco Research Institute, Inc, develop high-density, energy-efficient 3D embedded RAM for artificial intelligence applications.

High-resolution genome structural analyses combined with large-scale simulations show the arrangements of the genome’s spool-like structures affecting gene expression.

Scientists have shown that the population of the Yakushima sika deer has declined due to natural factors, suggesting that the population can be regulated without culling.

A look at Japan’s mimamoru approach suggests that adults’ non-intervention in kids’ fights allows children to nurture social and interpersonal skills on their own. Is it worth a try in other countries?

In collaboration with Kanazawa University, researchers from Osaka City University used high-speed atomic force microscopy (HS-AFM) to visualize at the nanometer level the movement of individual particles within the parasitic bacterium Mycoplasma mobile. After confirming the outline on the surface of the cell structure in an immobilized state with previous data gathered from electron microscopy, the team succeeded in visualizing the real-time movements of the internal structure by scanning the outside of the cell with HS-AFM.

Scientists from Japan, Europe and the USA have described a pathway leading to the accelerated flowering of plants in low-nitrogen soils. These findings could eventually lead to increases in agricultural production.

Researchers at The University of Tokyo Institute of Industrial Science repurpose food waste to build materials with a bending strength comparable to concrete and that still taste good

Chuo University and Hokkaido University researchers have found that infants take less than a second to completely process visual information and have the same temporal limitation in processing visual information as seen in adults.
