• Atomic catalyst unlocks the hidden value of plant waste
  Scientists have created a highly efficient catalyst that breaks down stubborn lignin from plant waste into useful chemicals under relatively mild conditions. By revealing exactly how the catalyst works at the atomic level, the discovery could help turn forestry and agricultural waste into renewable building blocks for fuels, plastics, and other materials.
• Newton’s 300-year-old law just passed its biggest test yet
  A massive test of gravity across the cosmos found that it behaves almost exactly as Newton and Einstein predicted, even across galaxy clusters hundreds of millions of light-years apart. The result weakens some modified-gravity explanations and strengthens the case that dark matter is behind the universe’s mysterious missing mass.
