A research team from the Urban and Transportation Systems Laboratory, Department of Architecture and Urban Systems, Toyohashi University of Technology (lead researcher: Dr. Mustafa Mutahari), has developed a quantitative policy evaluation framework for assessing how cities can attract startups while maintaining high living standards. In this study, the team evaluated the startup ecosystem under an air-front smart city using a model that integrates Quality of Life (QOL), Quality of Business (QOB), and accessibility from both digital and physical dimensions, and revealed that policy, accessibility, and QOL are the key determinants. This research was conducted as part of the JST e-ASIA Joint Research Program, an international collaborative project involving Japan, Thailand, and the Philippines, and the findings have been published in Smart Cities, an international academic journal.

A new study published in Big Earth Data presents phenological metrics derived from Earth observation (EO) satellite time series—such as greening onset, senescence, and growing season length—which are essential for crop monitoring but challenged by the massive scale of EO data exceeding local processing capacities, and introduces a free, open-source Web Crop Phenology Metrics Service (WCPMS) built on the Brazil Data Cube platform for server-side extraction from large datasets. It further demonstrates the tool’s effectiveness by estimating soybean sowing dates in Brazil using phenological metrics and validating the results against field data.

A group of Rice University students has turned a single semester course project into a peer-reviewed research paper, demonstrating a new way to make high-performance composite materials both stronger and more resistant to catastrophic failure. The study, published in Composites Part B, introduces an architectural approach to improving carbon fiber-reinforced polymer (CFRP) composites, materials widely used in aerospace for their strength and light weight but known for their vulnerability to sudden, brittle failure.

Mechanical engineers have designed a more effective and energy-efficient technology for cooling computer chips. Publishing May 7 in the Cell Press journal Cell Reports Physical Science, the researchers used a mathematical algorithm and advanced 3D printing method to produce pure copper cold plates that outperformed conventional cold plates and required less energy to run. If used to cool an entire data center, the technology would contribute only around 1.1% of the data center’s total energy usage compared to more than 30% for conventional air-cooling methods, the researchers estimate. 

A surprising breakthrough in anti-aging research raises hopes of delaying muscle aging and weakness by harnessing the potential of a garlic-derived compound, S-1-propenyl-L-cysteine (S1PC). Researchers identify a key role for S1PC in orchestrating a key inter-organ communication between fat tissue and the hypothalamus in the brain, thus supporting muscle function in aged mice. Elements of this signaling mechanism were also observed in humans, highlighting the potential of S1PC-based anti-aging interventions.

Circularly polarized luminescent materials emitting red to near-infrared light are of interest for technologies such as 3D displays and bioimaging. However, achieving high emission efficiency, stability, and durability simultaneously has remained a challenge. In a recent study, researchers at Kyushu University developed a new series of small luminescent radicals with exceptional photoluminescence efficiency and photostability. Their work demonstrates how a favorable electronic structure, chirality, and light emission can be achieved in a single molecular system.
