There is a lot of “buzz” and “hype” in the blogs and new reports being generated by … quote, “Scientists think a thin interstellar haze of graphite whiskers spewed from stars and supernovae would affect how different wavelengths of light pass through space.”
Because, quote, “In the study, published in today's issue of Science ScienceDaily (Feb. 29, 2008), Andrew Steele and Marc Fries of the Carnegie Institution's Geophysical Laboratory report the discovery of an unusual new form of carbon in minerals within meteorites dating from the formation of the solar system.”
Graphite Whiskers, Rather Than Dark Energy, Could Explain Dimness Of Stellar Explosions

I’ll leave the comment to others.

I haven't looked at this study in detail yet but I'll have a look. I can comment about dust and dark energy in general though. It has been long established now that it is extremely unlikely for any kind of dust to spoof dark energy. The abstract notes that these carbon fingers would absorb in the Infra-Red. This is indeed where important measures of the flux from supernovae are measured. However, if this was the case, you would expect to see a change in the relative intensities of the continuum radiation across the whole spectrum. Careful measurements have shown that this does not occur. Any dust that could spoof dark energy would have to be 'grey', in the sense that it absorbed light equally at all wavelengths. No known 'dust' can do this.
The other issue is that to fit the SN results by grey dust the density of the dust in the Universe has to evolve in a very odd way, there must be more not less dust in the past than there is today.
