From Here To Singularity

"The time from here to Singularity depends sensitively on the particulars of what we humans do during the next decade (and even the next few years)."

Physicists have ‘solved’ mystery of levitation

Not particularly singularity relevant, but neat nonetheless:

Levitation has been elevated from being pure science fiction to science fact, according to a study reported today by physicists.

Professor Ulf Leonhardt and Dr Thomas Philbin, from the University of St Andrews in Scotland, have worked out a way of reversing this pheneomenon, known as the Casimir force, so that it repels instead of attracts.

Their discovery could ultimately lead to frictionless micro-machines with moving parts that levitate But they say that, in principle at least, the same effect could be used to levitate bigger objects too, even a person.

The Casimir force is a consequence of quantum mechanics, the theory that describes the world of atoms and subatomic particles that is not only the most successful theory of physics but also the most baffling.

Now, using a special lens of a kind that has already been built, Prof Ulf Leonhardt and Dr Thomas Philbin report in the New Journal of Physics they can engineer the Casimir force to repel, rather than attact.
