It's a psionic discipline - basically telekinesis with a different user interface. Also the catchall name for what early (i.e., 23rd-century) human psions could do, albeit not without extensive cybernetic intervention. This is examined in (slightly) more detail in the annotations for Star-Crossed, IIRC.

Note that not all characters who were biotic in their Mass Effect incarnations are so in UF. (Most asari in the UF universe, for instance, are Force-sensitives, not psions, though very few follow the Jedi philosophy; they have their own traditions. The old West End Games Star Wars RPG had a name for this, but I can't remember now what it was - "alien Force adept" or some such.)
