The team developed a new optical measurement technique, “Atom Camera,” using a single ultracold atom at near absolute zero temperature as a camera. The technique visualizes not only light intensity distributions but also polarization distributions with a high spatial resolution below 100 nanometers. The method is expected to be useful in quantum computing and other emerging quantum technologies.

By electrochemically introducing phosphonate ester groups into conductive polymer films, researchers at Science Tokyo have addressed a fundamental trade-off between electronic charge transport and ion transport, overcoming a key performance limitation in organic electrochemical transistors (OECTs). The method enables precise tuning of polymer properties and can be applied to semicrystalline materials without redesigning monomers, supporting the development of improved biosensors and flexible electronic devices.

Kyoto, Japan -- Bright colors in animals are beautiful but often considered risky because they are more obvious to predators. However, conspicuous colors can also serve defensively, signaling toxicity or even luring predators away from more vulnerable body parts.

Previous studies have shown that the presence of predators such as dragonfly nymphs can induce tadpoles to develop bright orange tail coloration, an ability called phenotypic plasticity. But how this color change helps them avoid predation has not been clear. While observing tadpoles of the East Japan tree frog, Dryophytes leopardus, a team of researchers at Kyoto University was inspired to investigate how their predator-induced orange tails function as a defensive trait.

"After seeing these tadpoles with orange tails at the university's experimental farm, I wondered what role such a bright tail could have," says corresponding author Akihiro Noda.

In a major breakthrough for decentralized healthcare and environmental monitoring, researchers at Kumamoto University have successfully developed a palm-sized, battery-powered spectrophotometer that matches the performance of massive commercial laboratory equipment. Published in Sensing and Bio-Sensing Research, the study reveals a 99% reduction in device volume without sacrificing accuracy, paving the way for instant, on-site testing in hospitals, agricultural fields, and remote waterways.

An international team of researchers from Japan and Malaysia has shown that wild orangutan juveniles continue to consume their mother’s milk continuously until at least six and a half years of age, the longest breastfeeding period known among mammals. Using a new technique called fecal proteomics, the team detected milk-specific proteins in the feces of wild Bornean orangutans in Malaysian Borneo. The study also suggests that prolonged breastfeeding supports intestinal defenses and a healthy gut microbiome, helping sustain orangutans’ slow reproductive rates and lower juvenile mortality.

Clinical Dohsa-hou, also called Dohsa-hou, is a Japanese psychotherapy that explores the mind-body connection. Associate Professor Reika Nomura has worked as a clinical psychologist on the front lines of care both in hospitals and disaster-affected areas, where the gravity of human life is deeply felt. Motivated by her own experience of hospitalization and supporting a family member living with illness, she has demonstrated integrated engagement across clinical practice, research, and education. We interviewed her about Dohsa-hou and her hopes for the next generation of psychological professionals. She also shared her views on what it means to offer sincere support.

Researchers from Kyushu University and DENSO IT Laboratory, Inc. have proposed a new design method for coding schemes to improve depth precision in Indirect Time-of-Flight (I-ToF) cameras while considering practical sensor constraints. The method enhances noise robustness and measurement stability, making it suitable for real-world applications in autonomous robots and automotive systems.

The cradles of baby stars have a wheel-and-spoke like shape, with streams of gas converging toward a dense central hub. Using 3D simulations, researchers from Kyushu University and Nagoya University found that when an external shockwave strikes a gas cloud with a pinched magnetic field, it reorganizes the cloud into radial filaments. These findings open a new window into the environments where massive stars and star clusters are born.

Genetically engineered cyanobacteria developed at Institute of Science Tokyo (Science Tokyo), Japan, produce sulfated polysaccharides using sunlight and carbon dioxide. By transferring an entire gene cluster responsible for the production of a sulfated polysaccharide, the researchers enabled a non-producing cyanobacterial strain to produce such a polysaccharide. The research demonstrates a sustainable route for manufacturing biomaterials using photosynthesis, expanding the possibilities for synthetic biology and green chemistry applications.

Living cells cool much slower than our current understanding of heat conduction can explain, according to new research from the University of Tokyo. Researchers used two techniques — high-speed temperature mapping and artificial heating — to observe how heat dissipated from living cells and similar-sized artificial, fluid-filled sacs (liposomes). While heat dispersed quickly from the artificial liposomes as expected, cells cooled significantly more slowly due to other biomolecules within the cell. Understanding the process behind slower heat dissipation within cells could affect how we treat conditions linked to changes in body temperature, such as epilepsy, inflammation and cancer.
