An international team of physicists with the BigRIPS experiment taking place at the RIKEN Radioactive Isotope Beam Factory in Japan has determined the dripline for fluorine and neon isotopes. In their paper published in the ...
The Alpha Magnetic Spectrometer (AMS) collaboration, a large group of researchers from CERN and other institutes worldwide, has recently presented a series of precision measurements of the properties of cosmic Helium isotopes ...
In understanding the global carbon cycle, "black carbon"—decay-resistant carbon molecules altered by exposure to fire or combustion—has long been presumed to originate on land and work its way to the ocean via rivers ...
