Researcher finds a way to mimic curves in space-time
Here on Earth, it's rather difficult to replicate curved space-time -- to get that kind of effect in nature, you'd have to get uncomfortably close to black holes and other distant space objects. However, researcher Nikodem Szpak may have found a way to simulate that bend without facing oblivion. His proposed technique puts supercooled atoms in an optical lattice created by a laser field; so long as the laws of quantum mechanics and thermodynamics hold true, the atoms should behave like they're experiencing curved space-time. You can even change the lattice's pattern to mimic different circumstances, whether it's a moment right after the Big Bang or the surface of a star.
Levytator claims to be the world's first bendy escalator, has the patents to prove it (video)
You've seen conveyor belts before, most probably at your local airport ferrying beaten-up luggage in circles, but for some reason the same tech doesn't seem to have been applied to people yet. Leave it to City University London prof Jack Levy to correct that oversight with his eponymous Levytator -- an escalator that follows freeform curves (but not convention!) and offers a better "cost per usable step" than your typical moving stairs. Patented in Europe, the USA, and even China, all this thing needs is the gentle push of a kindly investor -- see the video after the break to determine if it's worth your cash. [Thanks, Conrad]
