How Can Data and AI Improve the Health of Our Cities?

Artificial intelligence systems endeavor to replicate or mimic human intelligence by combining datasets with iterative processing algorithms to learn from patterns and experience. From Siri, Alexa and other smart assistants to conversational bots and email spam filters, what once seemed like a technology pulled from science fiction has become ubiquitous in our daily lives. In […]

Blowing dust to cool fusion plasmas

Future tokamak fusion power reactors will generate heat beyond what current materials can withstand. Scientists have proposed various methods for cooling the edge of the magnetically confined fusion fuel, or plasma, to protect the walls of the surrounding tokamak. One approach is injecting impurities in the form of gases to help radiate away excess heat. […]

Electric Truck Hydropower, a flexible solution to hydropower in mountainous regions

In our transition towards a more sustainable future, hydropower will likely grow in importance as a renewable energy source. Despite its potential, innovation in hydropower technology has been slow in the last century. Conventional methods used today rely on two connected reservoirs with different water levels where the potential energy of the water is converted […]

New method for stabilizing the interfaces in solid-state lithium-ion batteries

In the endless quest to pack more energy into batteries without increasing their weight or volume, one especially promising technology is the solid-state battery. In these batteries, the usual liquid electrolyte that carries charges back and forth between the electrodes is replaced with a solid electrolyte layer. Such batteries could potentially not only deliver twice […]
