Astronomers from the Ohio State University (OSU) and University of Hawai’i have performed spectroscopic observations of a recently-discovered binary system known as LAMOST J2354, which contains a dark companion star. Results of the observational campaign, presented July 26 on the pre-print server arXiv, suggest that the unseen object is a massive white dwarf. Astronomers from the…
Have you ever considered how nanotechnology could transform our approach to clean energy? In recent research, we’ve been exploring nanoscale covalent organic frameworks (nano-COFs) that show exceptional potential for enhancing photocatalytic hydrogen production.

Betula ermanii, a tree species native to the high mountains in Japan and the cold and snowy regions of Russia, is usually tetraploid (possessing four genome sets). However, the species found on Shikoku Island and Kii Peninsula are diploid with only two genome sets, suggesting an ancestral lineage. Betula ermanii, a tree species native to the…
Researchers at University of Tsukuba have developed a unique technique for synthesizing commonly used polymers, such as polystyrene, using radical polymerization. Here, a remote spark discharge from a Tesla coil, which is a high-voltage, high-frequency generator allows the reaction to proceed without requiring conventional catalysts or polymerization initiators. Researchers at University of Tsukuba have developed a…
Neutrinos are the “ghost particles” in the Standard Model of Particle Physics. This is because they interact weakly with ordinary matter. An interesting property of neutrinos is that they can change their identities or “flavors” when they interact. Neutrinos are the “ghost particles” in the Standard Model of Particle Physics. This is because they interact weakly…
Researchers from Tokyo Metropolitan University have taken a big step in solving the mystery around why animals evolve sex chromosomes. It had long been proposed that sex chromosomes evolved to reduce “sexual conflict,” the evolution of features which are sub-optimal for either sex. Researchers from Tokyo Metropolitan University have taken a big step in solving the…
A biochemical breakthrough using simple carbon atoms, by Ken Yamada, Ph.D., and Anastasia Khvorova, Ph.D., has dramatically improved the stability and efficacy of a potential oligonucleotide therapeutic platform in mice. This discovery, published in Nature Biotechnology, has the potential to improve the durability of oligonucleotide drugs, including small interfering RNAs, and to bring these therapies…
Recent excavations at the Shimao site in Shaanxi, China, have revealed one of the earliest and, so far, largest bone needle workshops ever discovered. The research published in the Journal of Anthropological Archaeology by Hua Wang and colleagues provides valuable insights into craft specialization and early state formation in China during the transition from the…
A Falcon 9 rocket with a Cygnus supply freighter blasted off on a mission to the International Space Station on August 4, just a few days after a two-week break due to launch problems. A Falcon 9 rocket with a Cygnus supply freighter blasted off on a mission to the International Space Station on August 4,…
A team led by Professor Seo Dae-ha of the Department of Physics and Chemistry at DGIST has developed new real-time microscopy technology and successfully observed the behavior of “motor proteins,” which may hold the key to unraveling the efficient material transport strategy of cells. A team led by Professor Seo Dae-ha of the Department of Physics…
