https://www.edn.com/design/analog/4461000/A-technical-performance-based-view-of-opto-isolators-and-digital-isolators Galvanic isolators are devices that couple an electrical data or control signal across an insulation barrier without any flow of current through it, thereby enabling signals to be transferred while blocking noise. The insulation barrier also safeguards equipment and human operators from high voltages. The earliest isolators were optically coupled devices, also called opto-isolators →

Managing energy demand spikes with seasonal forecasts of heatwaves and cold spells https://horizon-magazine.eu/article/managing-energy-demand-spikes-seasonal-forecasts-heatwaves-and-cold-spells_en.html The impact of heavy droughts, heatwaves and cold spells on energy demand and supplies would be lessened with seasonal climate forecasts that allow energy companies to better predict spikes in usage ahead of time, researchers say. Researchers already have the ability to →

http://www.iflscience.com/health-and-medicine/scientists-have-successfully-reversed-the-aging-of-human-cells-in-the-lab/ This looks interesting: The researchers were able to reverse the aging process of some old human cells by delivering a specific molecule to their mitochondria, the structures within cells where energy is produced. This approach stops the cells from becoming senescent, a point at which they can no longer duplicate. Some researchers believe that →
