Gas hydrates are great alternative energy sources but they could also harm us and the environment, note geologists from the University of the Philippines.

An international research team have made unprecedentedly detailed observations of the earliest merger of galaxies ever witnessed. They suggest stars developed much faster and more efficiently than we thought. They used the James Webb Space Telescope (JWST) to observe the massive object as it was 510 million years after the Big Bang – i.e. around 13 billion years ago.

A new study highlights a potential therapeutic target for immune-related disorders, such as multiple sclerosis and asthma.

Researchers from Osaka University used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.

Researchers from the Institute of Industrial Science, The University of Tokyo and collaborating partners have created guidelines for the design of intercalated materials, which will accelerate research on energy storage, electronics, and more.

In celebration of International Women's Day, we are putting the spotlight on women experts from various fields who are open to speaking with international media about their research and advocacies.

A novel method for studying genes in testicular cells of living animals could lead to breakthroughs in male contraception and fertility treatments.

SANKEN researchers achieved the acceleration of adiabatic evolution of a single spin qubit in gate-defined quantum dots for the first time. After the pulse optimization to suppress quasistatic noises, the spin flip fidelity can be as high as 97.5% in GaAs quantum dots. This work may be useful to achieve fast and high-fidelity quantum computing.

In a study recently published in the journal SMALL, a weekly peer-reviewed scientific journal covering nanotechnology, published by Wiley-WCH, Germany, researchers from Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, Japan, collaborating with Professor Sarikaya, Seattle, USA, used frequency modulated atomic force microscopy to reveal the molecular architecture of genetically designed and point mutated peptides and their self-organizations each forming single-molecule thick, distinct biological crystals on atomically flat graphite and MoS2 surfaces, offering a potential platform for hybrid technologies such as bioelectronics, biosensors, and protein arrays.

The Pacific is taking a critical step to establish an Academy of Sciences and Humanities to unify and recognize Pacific scholars and their research to inform international decisions about the region.

Jun’ichi Yokoyama once amused his professors by proposing a far-fetched idea of using neutrinos and gravitational waves to observe the Universe. Decades later, he was proven right and contends young scientists should be nurtured to believe in themselves.

A new user-friendly tool helps researchers explore how gene activity is influenced by chemical modifications, providing insights into disease and paths to new treatments.

Molecules that are induced by light to rotate bulky groups around central bonds could be developed into photo-activated bioactive systems, molecular switches, and more.

A German aircraft flying out of Cairns is measuring the chemistry of the clouds above Australia and the Pacific.

Researchers from Osaka University have found that, after chronic social isolation, one form of ketamine—(R)-ketamine—is effective for restoring neuronal activation in a brain region known as the anterior insular cortex. This restored activation leads to improvements in social impairments in a mouse model of depression. Together, these findings indicate that (R)-ketamine is a promising treatment for social symptoms of depression and may lead to better quality of life for millions of people worldwide.

The effects of a phenomenon called tree masting on ecosystems and food webs can be better understood thanks to new theoretical models validated by real world observations.

In a study recently published in Nature Genetics, researchers from Nano Life Science Institute (WPI-NanoLSI), Kanazawa University explore chromatin accessibility, i.e., endogenous access pathways to the genomic DNA, and its use as a tool for gene editing.

Protecting Science in Times of Crisis is a comprehensive report addressing the urgent need for a new approach to safeguard science and its practitioners during global crises. With many conflicts spread over geographical zones, increasing extreme weather events, and natural hazards such as earthquakes in unprepared regions, this new report takes stock of what we have learned in recent years from our collective efforts to protect scientists and scientific institutions during times of crisis and suggests a way forward.

Collective ‘memory’ is one way to ensure that past mistakes in the evolution of science systems are not repeated after a crisis, disaster or conflict according to a University of Tokyo historian who has contributed to the International Science Council’s latest report: Protecting Science in Times of Crisis.

Researchers at Kanazawa University report in Journal of Cell Science on a novel role of the small Ca2+-binding protein S100A11 in focal adhesion disassembly.

An innovative and more efficient way to produce fumaric acid that not only reduces carbon dioxide emissions, but also reuses waste resources to make biodegradable plastics

Researchers from Osaka University found that the oral bacterium Streptococcus gordonii activates another bacterial species, Fusobacterium nucleatum, to produce large quantities of methyl mercaptan, a compound responsible for bad breath. Disrupting this interaction could therefore help treat halitosis, and possibly also help prevent the development of more serious tooth and gum disease.

Researchers from Osaka University and collaborating partners succeeded in biomanufacturing from chemically synthesized sugar for the first time in the world. With refinement of this technology, one can envision a future society in which the sugar required for biomanufacturing can be obtained "anytime, anywhere, and at high rate". In the future, biomanufacturing using chemically synthesized sugar is expected to be a game changer in the biotechnology field—including the production of biochemicals, biofuels, and food, where sugar is an essential raw material—ultimately leading to the creation of a new bio-industry.

The properties of supramolecular polymers are dictated by the self-assembled state of the molecules. However, not much is known about the impact of morphologies on the properties of nano- and mesoscopic-scale polymeric assemblies. Recently, a research team demonstrated how terminus-free toroids and random coils derived from the same luminescent molecule show different photophysical properties. The team also presented a novel method for purifying the toroidal structure.

Researchers from the Institute of Industrial Science, The University of Tokyo have solved a foundational problem in transmitting quantum information, which could dramatically enhance the utility of integrated circuits and quantum computing.
