Measuring nuclear reaction rates in the Laboratory is essential for interpreting and understanding astrophysical phenomena such as solar neutrinos, the age of globular clusters, nova and supernova nucleosynthesis, etc. Current laboratory innovations are focused on - the development and use of underground facilities to increase measurement sensitivity by reducing cosmic-ray background rates; the production and acceleration of beams of radioactive nuclei in order to measure the rates of reactions involved in explosive nucleosynthesis; together with the continuing development of more and more sophisticated detector systems. Examples will be presented from these areas, including: the status of critical reactions determining the rates of the proton-proton chain neutrinos; the rate of the 14N(p,γ) reaction relating to the rate of the CNO cycle and consequently to the age of globular clusters; measurement of the 26mAl(p,γ) reaction rate; and first measurements of the properties of nuclei, such as 78Ni and 132Sn, which are relevant to the r-process path.
