More Quick Neutrinos

I was told that New Scientist had yet another story on the impossibility of superluminal neutrinos, but it turns out to be yet another case of imposing a classical concept of energy on a phenomenomen that quite clearly won't be adequately explained by such a theory, if true. Weak logic makes poor news. Back in OPERA month, we mentioned classical tachyons, whose low energy states move at the fastest speed, but this old rule could easily be inverted in quantum gravity, so that tachyons travelling just faster than $c$ are the black sheep.

A more interesting article from this edition is a note on dark matter in globular clusters.
