stereo-array isotope labeling (SAIL), structures of large proteins (up to 50 kDa) can now be solved with ease with nuclear magnetic resonance (NMR) spectroscopy. NMR spectroscopy has been rapidly ...

Eventually, we created gas-powered engines, hydroelectric power, and even magnetic levitation (Maglev) for trains. Surprisingly, NASA will take us full circle with the solar sail. READ ...
