Kagome metals are a class of quantum materials with interesting properties that are characterized by a unique lattice structure resembling Japanese woven bamboo patterns of the same name (i.e., Kagome). Over the past decade, ...
A new Tel Aviv University study finds that prehistoric humans "recycled" discarded or broken flint tools 400,000 years ago to create small, sharp utensils with specific functions. These recycled tools were then used with ...
