Inconstant constants

ScienceDaily: Variable Physical Laws

This seems very important, although what exactly it means for cosmology is not at all clear:

On April 21 this year new findings were published in Physical Review Letters implying that a dimensionless constant – the ratio between the electron mass and the proton mass – has changed with time.

And shortly measurements will be presented in Monthly Notices of the Royal Astronomical Society showing that another dimensionless constant, called the fine structure constant, is also varying with time.
