New dual-cavity design emits more single photons that can carry quantum information at room temperature — ScienceDaily

MIT researchers have designed a way to generate, at room temperature, more single photons for carrying quantum information. The design, they say, holds promise for the development of practical quantum computers. Quantum emitters generate photons that can be detected one at a time. Consumer quantum computers and devices could potentially leverage certain properties of those…

Researchers find way to build potassium-oxygen batteries that last longer — ScienceDaily

Researchers have built a more efficient, more reliable potassium-oxygen battery, a step toward a potential solution for energy storage on the nation’s power grid and longer-lasting batteries in cell phones and laptops. In a study published Friday in the journal Batteries and Supercaps, researchers from The Ohio State University detailed their findings centering around the…

Progesterone could increase births in women with early pregnancy bleeding and previous miscarriage — ScienceDaily

Research led by the University of Birmingham suggests that giving progesterone to pregnant women with early pregnancy bleeding and a history of miscarriage could increase their chances of having a baby. The PRISM trial, funded by the National Institute for Health Research (NIHR) and co-ordinated by Birmingham Clinical Trials Unit in collaboration with Tommy’s National…
