With this view, it may be ethical to seed the cosmos as a last resort to save terrestrial life, but not to expand the reach of Earth life beyond our solar system. Another factor the authors ...

The hue produced by a similar mechanism is called ... Attempts to process a window pane to allow rays of light to bend or to broaden their reach often end up in the rays assuming colors of the ...

The researchers have produced a prototype betavoltaic battery with carbon-14, an unstable and radioactive form of carbon, called radiocarbon. "I decided to use a radioactive isotope of carbon because ...
