Mueller did not recommend any specific sentence. The filing says Papadopoulos' "false statements were intended to harm the investigation, and did so."

Using an advanced, new microscopy technique that can visualize chemical reactions occurring in liquid environments, researchers have discovered a new reason lithium-oxygen batteries -- which promise up to five times more energy than the lithium-ion batteries that power electric vehicles and cell phones -- tend to slow down and die after just a few charge/discharge cycles.
