In a study published March 5 in Science, Ke Cheng and his colleagues describe a therapy designed to enhance the heart’s own ability to protect and repair itself after injury. Cheng’s innovation in drug delivery points to a future where RNA therapy allows the body to produce its own medicine targeted at specific organs. 

A new study reports a promising approach to transform agricultural and industrial waste into high-performance porous carbon materials that could help improve soil and water conservation while addressing global waste management challenges.

Scientists in Sweden and the U.S. today reported the first-ever direct observation a type of short‑lived molecule that has shaped decades of thinking in atmospheric chemistry, combustion research and biomedical science.

 

Publishing in Science Advances, researchers from KTH Royal Institute of Technology, in Stockholm, and Kinetic Chemistry Research in Mountain View, California, say their discovery of long-theorized, oxygen-rich tetroxides has implications in a number of sciences, including atmospheric chemistry, biochemistry and medicine and combustion chemistry.

Researchers have proposed a novel methodology to optimize the placement of impedance relays in medium-voltage electrical distribution systems, where their application has traditionally been limited compared with transmission networks. By integrating clustering algorithms with metaheuristic optimization techniques, the approach enables a more strategic configuration of protection devices within complex and dynamic distribution grids. Simulation studies conducted using CYME software and the Ant Colony Optimization algorithm demonstrate that the proposed method can reduce failure frequency and improve the system’s response to fault conditions, contributing to greater reliability and resilience in electrical distribution infrastructure.

A new study shows how fireflies speed up or slow down their flashing to sync up with other insects, creating a beautiful and other-wordly light show.
