A smartphone app designed to tackle the underlying psychological causes of premature ejaculation can significantly improve sex life and delay ejaculation, while offering a way to reduce stigma around the condition, say researchers.

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.
