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.
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.
A clean energy future hinges on minerals such as copper, cobalt, lithium and rare earth elements. But the race to secure them puts pressure on the places where they are mined, often affecting communities contributing the least to climate change. To secure CRM sources, the United States and European Union are moving supply chains to aligned regions. But simply shuffling where minerals are mined does not automatically make extraction more ethical or sustainable. In a commentary published in Nature Energy, researchers propose a new framework of “just-shoring” to shift focus from competition and security to the rights and interests of those whose lands are most at risk.
