We reevaluate the hadronic vacuum polarisation contributions to the muon magnetic anomaly and to the running of the electromagnetic coupling constant at the Z-boson mass. We include newest 
cross-section data (among others) from the BABAR and VEPP-2000 experiments. For the muon 
we find for the lowest-order hadronic contribution 
, improving the precision of our previous evaluation by 21%. The full Standard Model prediction differs by 
from the experimental value. The five-quark hadronic contribution to 
is evaluated to be
