Study shows long tail on luna moth helps to thwart bat attacks (w/ Video)
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.
Falling faster—researchers confirm super-terminal raindrops
Five years ago, a research team at Michigan Technological University and Universidad Nacional Autanoma de Mexico (National University of Mexico) detected tiny, super-fast raindrops. The finding was unexpe ...
Physics of 'green waves' could make city traffic flow more smoothly
Best of Last Week – speed of light may be wrong, fungus fights resistant bacteria and link between pesticides and autism
Interaction between light and sound in nanoscale waveguide
Scientists from Ghent University and imec announce today that they demonstrated interaction between light and sound in a nanoscale area. Their findings elucidate the physics of light-matter coupling at these ...
Engineers take big step toward using light instead of wires inside computers
(Phys.org)—Stanford engineers have designed and built a prism-like device that can split a beam of light into different colors and bend the light at right angles, a development that could eventually lead ...
Goodbye Big Bang, hello black hole? A new theory of the universe's creation
Could the famed "Big Bang" theory need a revision? A group of theoretical physicists suppose the birth of the universe could have happened after a four-dimensional star collapsed into a black hole and ejected ...
New high-speed camera system reveals what snow looks like in midair
University of Utah researchers developed a high-speed camera system that spent the past two winters photographing snowflakes in 3-D as they fell – and they don't look much like those perfect-but-rare snowflakes ...
Physicist suggests speed of light might be slower than thought
SheerWind claims its INVELOX wind turbine produces 600% more power
Enclosed tube maglev system tested in China
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.
Algorithm recovers speech from vibrations of potato-chip bag filmed through soundproof glass
Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were ...
