Using the latest available cosmological data and working within the framework of $\\Lambda\\mbox{CDM}$, we first update the measurement of the Newton's constant for all matter: $G_N=7.26^{+0.27}_{-0.27}\\times 10^{-11}\\,\\mbox{m}^{3}\\mbox{kg}^{-1}\\mbox{s}^{-2}$, which differs by $2.2 \\sigma$ from the standard laboratory-based value.
