Finding new species in unassuming settings brings light to further exploration and conservation efforts to preserve the unique diversity in groundwater environments

Histone variants help establish DNA methylation at transposons (jumping genes) while preventing this epigenetic modification from spreading to essential genes in plants, reveals a study from Institute of Science Tokyo. By revealing how these chromosome-associated proteins guide the formation of precise epigenomic patterns, the findings provide new insights into the selective silencing of transposons, laying the groundwork for future epigenome-editing technologies for crop improvement and disease research.

Researchers at the University of Osaka, Shimane University, and Kyoto Sangyo University have now theoretically identified an unusual pattern of vibrations that emerges just before a crystal made of regularly arranged grains yields. Many vibrational modes soften simultaneously along particular directions, while long-wavelength waves travel more slowly than shorter ones. The findings reveal a possible physical precursor to failure in highly ordered particulate materials.

A research team led by Associate Professor Junji Konuma of Toho University, in collaboration with Nobuaki Nagata of the National Museum of Nature and Science and Professor Teiji Sota of Kyoto University, reconstructed the evolutionary and geographic history of this beetle species by combining genetic data from 170 individuals sampled at 70 sites with morphological data from 50 populations. These analyses suggested that body shape underwent adaptive divergence not only among islands—including Hokkaido and Sado Island—but also between regions within Honshu, the largest island of Japan.

A simple flame-synthesis method can produce highly active catalysts for converting carbon dioxide into methane, as reported by researchers from Science Tokyo. The team used flame-assisted spray pyrolysis to manufacture nickel–cerium oxide catalysts with finer nanoparticles and more active sites than conventional methods. These catalysts achieved outstanding methanation performance while remaining suitable for large-scale production, offering a practical route toward carbon-neutral fuel technologies.
