Best of Last Week – Parallel worlds, China completes moon round trip and progress in preventing GI cancers
(Phys.org) —Impressive things were happening in physics and the sciences in general last week, starting with a radical new theory from physicists at Griffith University—they are proposing the idea of the existence and interaction of parallel worlds—a many interacting worlds theory ...
Now hear this: Simple fluid waveguide performs spectral analysis in a manner similar to the cochlea
Best of Last Week – Two mysterious bursts from space, new developments with batteries and fingertip reader for the blind
Artificial spacetime experiment could show tantalizing effects of gravitational waves
Solitary acoustic waves observed to propagate at a lipid membrane interface
Independent research group testing D-Wave Two finds no quantum speedup
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 ...
Earth's surprise inside: Geologists unlock mysteries of the planet's inner core
Seismic waves are helping scientists to plumb the world's deepest mystery: the planet's inner core.
Planck: Gravitational waves remain elusive
Despite earlier reports of a possible detection, a joint analysis of data from ESA's Planck satellite and the ground-based BICEP2 and Keck Array experiments has found no conclusive evidence of primordial ...
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.
Acoustic tweezers manipulate cell-to-cell contact
Sound waves can precisely position groups of cells for study without the danger of changing or damaging the cells, according to a team of Penn State researchers who are using surface acoustic waves to manipulate ...
Electron spin could be the key to high-temperature superconductivity
Swiss scientists take a significant step in our understanding of superconductivity by studying the strange quantum events in a unique superconducting material.
Tabletop experiment could detect gravitational waves
(Phys.org)—A coin-sized detector might observe gravitational waves before the giant Laser Interferometer Gravitational-Wave Observatory (LIGO), according to two Australian physicists.
Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
