Query: A consistent explanation for $^{12}$C/$^{13}$C, $^7$Li, and $^3$He
  anomalies in red giant stars   The observations of carbon isotopic ratios in evolved stars suggest that non
standard mixing is acting in low mass stars as they are ascending the red giant
branch. We propose a simple consistent mechanism, based on the most recent
developments in the description of rotation-induced mixing by Zahn (1992),
which simultaneously accounts for the low $^{12}$C/$^{13}$C ratios in globular
cluster and field Pop II giants and for the lithium abundances in metal-poor
giant stars. It also leads to the destruction of $^3$He produced on the main
sequence in low mass stars. This should both naturally account for the recent
measurements of $^3$He/H in galactic HII regions and allow for high values of
$^3$He observed in some planetary nebulae.
