New analysis points to Planet X again, and perhaps more of them
This was discussed a long time ago in this thread:

Although this latest research doesn't involve new observations, it does rely on observations from Maun Kea and they claim it points to a planet that's larger than the Earth and other smaller planetoids that have had their orbits affected by this planet. Personally, I'm not convinced at this point but it is an interesting argument nevertheless.
""We predict the existence of an Earth-like planet and several trans-Neptunian objects on peculiar orbits in the outer solar system, which can serve as observationally testable signatures of the putative planet's perturbations.""
"According to the duo, the proposed ninth planet would have a mass between one-and-a-half and three times that of the Earth.
Its existence would explain three of the fundamental properties of the Kuiper Belt, the pair added.
Specifically, how there is a prominent set of trans-Neptunian objects beyond Neptune's gravitational influence, the significant population of objects with a high orbital inclination, and the existence of some extreme bodies - like the dwarf planet Sedna - with peculiar orbits."
