Abstract: We present recent results for <superscript>4</superscript>He and <superscript>6</superscript>Li obtained with improved NN interactions derived from chiral effective field theory up to N<superscript>4</superscript>LO. The many-body calculations are performed order-by-order in the chiral expansion. At N<superscript>3</superscript>LO and N<superscript>4</superscript>LO additional renormalization using the Similarity Renormalization Group is adopted to improve numerical convergence of the many-body calculations. We discuss results for the ground state energies, as well as the magnetic moment and the low-lying spectrum of 6Li. [ABSTRACT FROM AUTHOR]
