Best of Last Week – A way to measure variations in the speed of light, a slower universe and plucking hair
Absence of gravitational-wave signal extends limit on knowable universe
Imagine an instrument that can measure motions a billion times smaller than an atom that last a millionth of a second. Fermilab's Holometer is currently the only machine with the ability to take these very ...
New understanding of electromagnetism could enable 'antennas on a chip'
A team of researchers from the University of Cambridge have unravelled one of the mysteries of electromagnetism, which could enable the design of antennas small enough to be integrated into an electronic ...
Unraveling the origin of the pseudogap in a charge density wave compound
The pseudogap, a state characterized by a partial gap and loss of coherence in the electronic excitations, has been associated with many unusual physical phenomena in a variety of materials ranging from cold ...
Device extracts rare tumor cells using sound
A simple blood test may one day replace invasive biopsies thanks to a new device that uses sound waves to separate blood-borne cancer cells from white blood cells.
Camera chip provides superfine 3-D resolution
Imagine you need to have an almost exact copy of an object. Now imagine that you can just pull your smartphone out of your pocket, take a snapshot with its integrated 3-D imager, send it to your 3-D printer, ...
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 ...
New insights found in black hole collisions
New research provides revelations about the most energetic event in the universe—the merging of two spinning, orbiting black holes into a much larger black hole.
Now hear this: Simple fluid waveguide performs spectral analysis in a manner similar to the cochlea
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 ...
Sonic booms in nerves and lipid membranes
Landmark study proves that magnets can control heat and sound
Researchers at The Ohio State University have discovered how to control heat with a magnetic field.
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.
