Hydrogen and oxygen ions escaping from Earth’s upper atmosphere and combining on the moon could be one of the sources of the known lunar water and ice, according to new research by University of Alaska Fairbanks Geophysical Institute scientists. The work led by UAF Geophysical Institute associate research professor Gunther Kletetschka adds to a growing body of research about […]
Using new analyses, scientists have just found the last two of the five informational units of DNA and RNA that had yet to be discovered in samples from meteorites. While it is unlikely that DNA could be formed in a meteorite, this discovery demonstrates that these genetic parts are available for delivery and could have […]
