• The biggest problem with solid-state batteries may finally be solved
  Researchers solved the mystery of how soft lithium dendrites crack the hard ceramic inside solid-state batteries, triggering short circuits. The breakthrough could help engineers build safer, longer-lasting batteries for smartphones, electric vehicles, and other electronics.
• Heidelberg physicists just united two opposing quantum theories
  A new quantum theory bridges two rival models of how impurities behave inside many-particle systems, resolving a problem that has challenged physicists for decades. The findings could reshape experiments on ultracold atoms, semiconductors, and other exotic forms of quantum matter.
