Ramp metering and speed limits to prevent traffic jams
EPFL researchers showed that by managing the access to freeway junctions and moderating the speed limit on the express lanes it is possible to reduce delays by over 12% across the highway system.

Running faster equals disaster
Trading maximum speed for manoeuvrability may be essential to surviving a run-in with a predator, a new study shows.
What Google Fiber may mean for North Carolina, NC state and R&D
On Jan. 27, Google announced that it would be expanding its fiber-optic network, Google Fiber, into four new metropolitan areas: Raleigh-Durham, Charlotte, Atlanta and Nashville. So what?
Researchers determine key element in circadian clock speed
In a discovery that may lead to new treatments for sleep disorders, jet lag and other health problems tied to circadian rhythms, researchers at Dartmouth's Geisel School of Medicine have identified a determinant ...
Weighing gas with sound and microwaves
NIST scientists have developed a novel method to rapidly and accurately calibrate gas flow meters, such as those used to measure natural gas flowing in pipelines, by applying a fundamental physical principle: ...
Why is Andromeda coming toward us?
I don't want to alarm you, but there's a massive galaxy heading our way and will collide with us in a few billion years. But aren't most galaxies speeding away? Why is Andromeda on a collision course with ...
Physicists find a new way to slow the speed of light
New analysis shows a way to self-propel subatomic particles
Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No physical object can change its speed unless some outside force acts on it.
Beijing team proposes effortless phone charging with light beams
Are aliens watching old TV shows?
You've probably heard the trope about how aliens have been watching old episodes of "I Love Lucy" and might think these are our "historical documents". How far have our signals reached?
