Recent progress on Vinogradov's mean value theorem has resulted in improved estimates for exponential sums of Weyl type. We apply these new estimates to obtain sharper bounds for the hunck H(k) in the Waring-Goldbach problem. We obtain new results for all exponents k8, and in particular establish that H(k) ≤ (4k - 2) log k + k - 7 when k is large, giving the first improvement on the classical result of Hua from the 1940s.
