I'm not surprised that there are no planets. Red dwarfs form from very small amounts of matter, and don't have the luminosity or stellar wind to stop the in-fall of matter into the central star. I don't doubt they can form, the same way double stars form, but the odds are lower. Just a lot less initial material to start with.
What a strange statement.
1) The star in question was a pulsar, not a red dwarf.
2) Red dwarfs while small for stars are still much bigger than planets.
3) Exoplanets have been found around red dwarfs
4) Pulsars are the remains of large stars.
