MIT engineers developed a fuel cell that offers more than three times as much energy per pound compared to lithium-ion batteries. Powered by a reaction between sodium metal and air, the device could be lightweight enough to enable the electrification of airplanes, trucks, or ships.
Trees, shrubs, and other plants along roads and sidewalks play an important role in making cities more resilient to climate change, improving public health, and advancing environmental justice. Yet, tracking its distribution and change over time remains a major challenge – especially across large, rapidly urbanizing regions of the world. A new IIASA-led study addresses this gap.
Inspiration can hit anytime, anywhere—and come from just about anything. “I was walking my dog and watching a squirrel jump from tree branch to tree branch,” says David Saldaña, an assistant professor of computer science and engineering at Lehigh University. “I started thinking about how quickly the animal has to adapt to the different properties of each branch and to the forces generated by their movement. And that’s when the idea hit me—how could we get robots, especially aerial robots, to adapt like that?” Saldaña, who leads the SwarmsLab, recently received nearly $600,000 in funding through the National Science Foundation’s Faculty Early Career Development (CAREER) Program to answer that question. His research will explore how to expand the capabilities of aerial robots so they can manipulate and transport flexible objects such as cables, rods, hoses, and plastic sheets. Potential applications could range from construction and disaster response to industrial automation.
Advances in human stem cell-derived disease models have the potential to augment our predictive power for the efficacy and safety of new drugs. This technology, which complements existing approaches, is poised to reduce R&D costs and accelerate the development of new therapies for patients.
The International Society for Stem Cell Research (ISSCR) has assembled an international consortium of cross-sector thought leaders from industry, academia, and regulatory science to enable the widespread, responsible adoption.
The wearable smart photonic wristband proposed in this work achieves precise assessment of cardiorespiratory function and effective biometric identification. It not only excels in response speed, long-term stability, and durability but also maintains high-precision monitoring across various application scenarios and individual differences, demonstrating its practicality and adaptability. Additionally, the demonstration of biometric identification capabilities opens up new possibilities for personal health services. This research finding holds broad application prospects in the prevention, treatment, and daily health management of cardiorespiratory diseases, and is expected to have a positive impact on people's healthy lives.
