The IUCAA/IAP group have a constraint on (\Delta \alpha/\alpha) evolution
with redshift which makes it look like the Webb et al results are only
as significant as cosmic topology detections :(


\Delta\alpha / \alpha = (-0.06\pm0.06)e-5

The individual values range from -1e-5 to +1e-5  - see Fig.15 on p22

In other words, we should keep checking, but not yet get too excited.
