Tiny chip mimics brain, delivers supercomputer speed
Researchers Thursday unveiled a powerful new postage-stamp size chip delivering supercomputer performance using a process that mimics the human brain.
The first ever photograph of light as both a particle and wave
(Phys.org)—Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at ...
Researchers use sound to slow down, speed up, and block light
How do you make an optical fiber transmit light only one way? Researchers from the University of Illinois at Urbana-Champaign have experimentally demonstrated, for the first time, the phenomenon of Brillouin ...
Scientists set quantum speed limit
University of California, Berkeley, scientists have proved a fundamental relationship between energy and time that sets a "quantum speed limit" on processes ranging from quantum computing and tunneling to ...
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.
Adding leap second this year expected to cause Internet problems
Study finds possible alternative explanation for dark energy
(Phys.org)—Dark energy is an unknown form of energy that is proposed to drive the accelerated expansion of the universe. A new study by University of Georgia professor Edward Kipreos suggests that changes ...
Engineers build time cloak that hides messages in laser light
Shaking the topological cocktail of success
Graphene is the miracle material of the future. Consisting of a single layer of carbon atoms arranged in a honeycomb lattice, the material is extremely stable, flexible, highly conductive and of particular ...
Physicists propose identification of a gravitational arrow of time
A new spin on virtual reality helps engineers read robots' minds
In a darkened, hangar-like space inside MIT's Building 41, a small, Roomba-like robot is trying to make up its mind.
Breakthrough allows researchers to watch molecules 'wiggle'
A new crystallographic technique developed at the University of Leeds is set to transform scientists' ability to observe how molecules work.
Water in the solar system predates the Sun
Water was crucial to the rise of life on Earth and is also important to evaluating the possibility of life on other planets. Identifying the original source of Earth's water is key to understanding how life-fostering ...
