I have a new story posted by New Scientist:

“Dwarf galaxies dancing around the spiral galaxy Andromeda have boosted a controversial alternative to the idea of dark matter – the invisible stuff that most astronomers think makes up about 80 per cent of the matter in the universe.



Researchers looking at the speeds of stars in Andromeda's satellite galaxies have found that their motion is a near-perfect fit with what is predicted by modified Newtonian dynamics, or MOND. According to MOND, alterations to Newton's laws of motion and gravity can explain at least some of the observed effects that have been attributed to dark matter.”
