Computers Faster Only for 75 More Years? Physicists determine nature's limit to making faster processors
With the speed of computers so regularly seeing dramatic increases in their processing speed, it seems that it shouldn't be too long before the machines become infinitely fast -- except they can't.

Faster than light neutrinos? More like faulty wiring
You can shelf your designs for a warp drive engine (for now) and put the DeLorean back in the garage; it turns out neutrinos may not have broken any cosmic speed limits after all.

MIT takes aim at ‘phantom’ traffic jams
(PhysOrg.com) -- Countless hours are lost in traffic jams every year. Most frustrating of all are those jams with no apparent cause — no accident, no stalled vehicle, no lanes closed for construction.

Speed limit
A road speed limit is the maximum speed allowed by law for road vehicles. Speed limits are commonly set and enforced by the legislative bodies of nations or provincial governments, such as countries within the world.
The first maximum speed limit was the 10 miles per hour (16 km/h) limit introduced in the United Kingdom in 1861.
The Isle of Man is the only place in the world that does not have a general speed limit. In Germany, over 50% of the autobahn system remains free from speed limits.
Currently, the highest posted speed limit in the world is 140 kilometres per hour (87 mph) on Polish motorways , although a variable speed limit up to 160 kilometres per hour (99 mph) was permitted experimentally on a stretch of Austrian motorway in June 2006.
