The neutron energy output from a nuclear device detonation can affect the deflection of an asteroid.
U.S. energy flow chart
// S&T Highlights
Americans used approximately 7 percent less energy in 2020, due in part to the COVID-19 pandemic, according to energy flow charts released by Livermore.
Artist's rendeing of hydrogen gas bubbles forming  a thin layer of gallium oxynitride formed on gallium nitride surfaces.
// S&T Highlights
A research team uncovered a surprising, self-improving property in a silicon/gallium nitride photosynthesis device that contributes to the material’s highly efficient and stable performance in converting light and water into carbon-free hydrogen.
