They have just measured a better value for G, the granviational constant.

Announcement of New Value

"After combining all of the measurements we get a value of G = 6.673 87(0.000 27)10^11 m^3 kg^1 s^2. This new value is 5 parts in 10^5 smaller than our previous published values. "

Thanks SelfAdjoint.
from the same source: The new measurements have used both stainless steel and copper large masses. The values of G for the two sets of masses are in good agreement.
Further constraining differences in G due to nucleon type (etc).
