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.

Spin waves are a promising way to reduce the energy-consumption of computing. New research shows that sending spin waves along a zig-zag path boosts the signal over 5,000 times compared to previous methods.

Humans have evolved to be able to link intentions to emotions or physical actions. This is why we may approach someone with open arms but flee if someone approaches using threatening body language. While AI can accurately identify emotions, it struggles to derive intention from them. A research group, with the help of performers from Japan and Taiwan, has helped facilitate a means to bridge this gap.

As a growing share of total power output comes from wind turbines, sudden spikes in power generation from unpredictable changes in atmospheric conditions is becoming an increasingly urgent and potentially dangerous threat to grid stability. Using a 20 km-wide wind farm as a giant physics experiment, researchers have now developed a framework to predict the risk of power fluctuations for individual turbines, farms, and the whole grid, based on existing geospatial data. Their model will help establish the risk profile of existing and future developments, providing a powerful tool to ensure reliable and sustainable power generation for plant operators, grid engineers, and energy planners.
