• Scientists find a surprising clue to why the universe’s expansion doesn’t add up
  Tiny magnetic fields created shortly after the Big Bang may help explain the long-running disagreement over how fast the universe is expanding. Detailed simulations show that these primordial fields could have changed the formation of hydrogen in the early universe, affecting the cosmic microwave background and the expansion rate inferred from it.
• Scientists just found a new way to make hydrogen from water
  A new light-activated material can efficiently produce hydrogen from water without requiring an additional expensive metal catalyst. Researchers say its unusual sulfur-based chemistry could point toward cheaper and more practical ways to turn sunlight into clean fuel.
