It's been known for 30 years that Mother Nature once did nuclear chain reactions by her lonesome. Now, Researchers at Washington University in St. Louis have analyzed the isotopic structure of ...

FROM an examination of the hyperfine structure of certain lines of the arc spectrum of iridium, Prof. B. Venkatesachar and L. Sibaiya 1 have recently concluded that iridium must have two isotopes, and ...

Nuclear-magnetic-resonance spectroscopy can determine the three-dimensional structure of proteins in solution. However, its potential has been limited by the difficulty of interpreting NMR spectra in ...

To operate a nuclear power plant like Three Mile Island, hundreds of highly trained employees must work in concert to generate power from safe fission, all the while containing dangerous nuclear ...
