Researchers find that iron powder, an inexpensive alternative to activated carbon, does a better job at filtering PFOS from water—it’s 26 times more effective.

Scientists from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences demonstrated that DNA methylation—a form of epigenetic variation or change in gene expression—mediates the transgenerational inheritance of acquired cold tolerance in rice.

Researchers at the FAMU-FSU College of Engineering have designed a liquid hydrogen storage and delivery system that could help make zero-emission aviation a reality. Their work outlines a scalable, integrated system that addresses several engineering challenges at once by enabling hydrogen to be used as a clean fuel and also as a built-in cooling medium for critical power systems aboard electric-powered aircraft.

With the rapid development of the space industry, enhancing the stealth and survivability of spacecraft has become a critical challenge. Professor Qiang Li’s team at Zhejiang University has developed an innovative multilayer thin-film camouflage device, enabling invisibility across H, K, MWIR, and LWIR bands while efficiently radiating heat to address thermal control issues in space. This technology achieves precise management of solar and thermal radiation, offering significant support for future space exploration.
