The AMS-02 collaboration has released preliminary data on the antiproton fraction in cosmic rays. The surprisingly hard antiproton spectrum at high rigidity has triggered speculations about a possible primary antiproton component originating from dark matter annihilations. In this note, we employ newly available AMS-02 boron to carbon data to update the secondary antiproton flux within the standard two-zone diffusion model. The new background permits a considerably better fit to the measured antiproton fraction compared to previous estimates. This is mainly a consequence of the smaller slope of the diffusion coefficient favored by the new AMS-02 boron to carbon data.

Evidences of low-diffusion bubbles around Galactic pulsars
A sample of 27 Galactic pulsar wind nebulae shows a diffusion coefficient about two orders of magnitude below the Galactic average, implying large low-diffusion bubbles around these pulsars.
