Interestingly, Wikipedia suggests that the mechanism is relatively easy (read: already successfully done in rats) to manipulate in some cases to restore (partially and temporarily at least) the superior learning ability that children have and adults lose (probably at the cost of degrading some of the already learned memories and skills).
It would be nice to have a pill you could take when trying to learn a new language, for example. If that works, it might be even more useful, e.g. to help learn skills that a child could not even try to practice. I mean, we can’t tell if the young brain is better at “getting” quantum mechanics intuitively, because other changes in the brain are needed (which only adults have access to) before you can really begin to think about it, and it’s hard to test if someone who flies (e.g. a plane) regularly since birth would have better vertical awareness orientation, because planes are too dangerous to let children try to fly them before they learn to walk.
(I suspect that much of the difference in intuitiveness between 3D and 4D universes is actually “learned” by the brain, rather than a consequence of the brain existing in a 3D universe. Weak evidence is that blind-from-birth people who get their vision restored can’t really make much sense of what they see, though that could be specific to vision; incidentally, such people would be excellent test subjects. It would be unethical to raise a child in VR, but there’s no reason why an adult couldn’t try living in it for a while. The Oculus Rift is already good enough I expect, though I’m not sure we can do good-enough real-time stereo renderings of 4D simulations with usual hardware.)
I only just learned about this today, so I don’t put a lot of weight in my conclusion, but this sounds like the most promising first step to superhuman (relative to today) intellectual skills.

I don’t really think that children have a superior ability at learning languages.
There are plenty of adults who can learn a new language in under a year if they undergo complete immersion and use mnemonics to help them.
I think children are usually only better than adults is bad at learning or if the adult has to unlearn a bunch of things that he learned to practice the new skill.
At least some things are easier for (most) children than for (most) adults. For example, most adults will have to work very hard to speak a foreign language without an accent. Children who were exposed to a second language, even if they don’t speak it for years, will be able to pronounce it correctly later. See this.
I suspect some grammatical structures are also harder to acquire later, given how hard it is for adults to learn syntax elements that don’t exist in their native language (see the stereotype about foreigners always forgetting “the” in English).
