Engineers solve a mystery on the path to smaller, lighter batteries A discovery by MIT researchers could finally unlock the door to the design of a new kind of rechargeable lithium battery that is more lightweight, compact, and safe than current versions, and that has been pursued by labs around the world for years. The key to this potential leap in battery technology is replacing the liquid electrolyte that sits between the positive and negative electrodes with a much thinner, lighter layer of solid ceramic material, and replacing one of the electrodes with solid lithium metal. This would greatly reduce the overall size and weight of the battery and remove the safety risk associated with liquid electrolytes, which are flammable. But that quest has been beset with one big problem: dendrites. Article @EverythingScience

Wormholes May Already Have Been Detected, Physicists Say Hypothetical bridges connecting distant regions of space (and time) could more or less look like garden variety black holes, meaning it's possible these mythical beasts of physics have already been seen. Thankfully however, if a new model proposed by a small team of physicists from Sofia University in Bulgaria is accurate, there could still be a way to tell them apart. Article @EverythingScience

Cosmic chocolate pralines? General neutron star structure revealed The study of the sound speed has revealed that heavy neutron stars have a stiff mantle and a soft core, while light neutron stars have a soft mantle and a stiff core—much like different chocolate pralines.
