AB  - The NEWS-G collaboration is searching for light dark matter using single-electron-threshold Spherical Proportional Counters (SPCs) filled with light gaseous targets (H, He, Ne). NEWS-G has built a new 140 cm diameter SPC equipped with a multi-anode ACHINOS sensor. Robust calibrations with a UV laser and an $\mathrm{^{37}}$Ar source were performed to characterize the detector response to low energy events and achieve statistical background rejection. This work presents preliminary results from physics data taken with methane, leading to world-leading spin-dependent sensitivity under 2 $\mathrm{GeV/c^{2}}$ WIMP masses.
