Iâ(TM)ve had sleep studies before with varying results from mild to moderate apnea, likely depending on my weight. It would be nice to keep track of it more often because I donâ(TM)t do well with CPAPs (too many sinus infections). Im going to hold out until it actually gets FDA approval and there are some positive anecdotes out there.

Microscopic Wormholes Possible In Theory (phys.org) 52

An anonymous reader quotes a report from Phys.Org: Wormholes play a key role in many science fiction films -- often as a shortcut between two distant points in space. In physics, however, these tunnels in spacetime have remained purely hypothetical. An international team led by Dr. Jose Luis Blazquez-Salcedo of the University of Oldenburg has now presented a new theoretical model in the science journal Physical Review Letters that makes microscopic wormholes seem less far-fetched than in previous theories. [...] The researchers chose a comparatively simple "semiclassical" approach. They combined elements of relativity theory with elements of quantum theory and classic electrodynamics theory. In their model they consider certain elementary particles such as electrons and their electric charge as the matter that is to pass through the wormhole. As a mathematical description, they chose the Dirac equation, a formula that describes the probability density function of a particle according to quantum theory and relativity as a so-called Dirac field.

As the physicists report in their study, it is the inclusion of the Dirac field into their model that permits the existence of a wormhole traversable by matter, provided that the ratio between the electric charge and the mass of the wormhole exceeds a certain limit. In addition to matter, signals -- for example electromagnetic waves -- could also traverse the tiny tunnels in spacetime. The microscopic wormholes postulated by the team would probably not be suitable for interstellar travel. Moreover, the model would have to be further refined to find out whether such unusual structures could actually exist. "We think that wormholes can also exist in a complete model," says Blazquez-Salcedo.

Comment Why not a 'nsfw' subdomain at least? (Score 4, Insightful) 76

There's plenty of useful stuff on Reddit so I don't want to filter it outright - but I do wish they would at least move the porn stuff to a subdomain so that it can be filtered. Yes, I agree that if a kid wants to find porn* hard enough, he will - but on Reddit it's WAY too easy to do, unless you block the site completely.

*Honestly, it's not "porn" I'm so concerned about. It's the more extreme stuff, plus the NSFL death/gore videos - things that can easily be stumbled upon accidentlally over there.
