Advances in lithium-metal batteries, paving the way for safer, more powerful devices      (via sciencedaily.com)     Original source 

The boom in phones, laptops and other personal devices over the last few decades has been made possible by the lithium-ion (Li-ion) battery, but as climate change demands more powerful batteries for electric vehicles and grid-scale renewable storage, lithium-ion technology might not be enough. Lithium-metal batteries (LMBs) have theoretical capacities an order of magnitude greater than lithium-ion, but a more literal boom has stymied research for decades.

Cultural artifacts serve as 'cognitive fossils,' helping uncover the psychology of the past      (via sciencedaily.com)     Original source 

No two societies in history think exactly alike. In fact, the mindset of a given society throughout history can help historians unpack important clues about the effects of psychological shifts -- such as more social trust or more openness. Researchers explain how modern computing methods like text mining, face detection algorithms, and melodic extraction programs can enable large-scale analysis of cultural artifacts such as paintings, stories, or clothing to uncover this psychological data.
