David Thomson and Louis Lanzerotti are team members of the HISCALE experiment on board Ulysses, a joint mission between ESA and NASA. Together with colleagues Frank Vernon, Marc Lessard and Lindsay Smith, they present evidence that proves that Earth moves to the rhythm of the Sun. They show that distinct, isolated tones, predicted to be generated by pressure and gravity waves in the Sun, manage to reach Earth and are detectable in our environment.
Thomson and colleagues have discovered these tones in seismic data and have found them in Earth’s magnetic field and atmosphere, and even in voltages induced on ocean cables, along with a wide variety of terrestrial systems. Although these tones are all around us, it would not be possible for us to hear them, even if we listened very closely.
According to Thomson, data from Ulysses provided an important clue as to how these sounds generated deep inside the Sun reach the Earth.
His team also present new evidence for these tones in various terrestrial systems here on Earth. They also provide an explanation for the mechanism by which these tones, originating from deep inside the solar interior manage to make their way to Earth, and pervade our environment.

'Good vibrations' from deep-sea smokers may keep fish out of hot water
So you're a fish. Right now some tubeworm tartare and clams on the half shell would really hit the spot, so you're headed for the all-night café. "All-night" being the operative word because the volcanic ridge you're tooling along is nearly 1.5 miles below the surface. The term "where the sun don't shine" perfectly describes the place. It's pitch black. Darn, but what's that loud rumbling up ahead? Must be one of those pesky black smokers. Some of those babies can fry your face off. A detour is highly indicated.

Superfluid helium-4 whistles just the right tune
University of California, Berkeley, physicists can now tune in to and hear normally inaudible quantum vibrations, called quantum whistles, enabling them to build very sensitive detectors of rotation or very precise gyroscopes.
A quantum whistle is a peculiar characteristic of supercold condensed fluids, in this case superfluid helium-4, which vibrate when you try to push them through a tiny hole. Richard Packard, professor of physics at UC Berkeley, and graduate student Emile Hoskinson knew that many other researchers had failed to produce a quantum whistle by pushing helium-4 through a tiny aperture, which must be no bigger than a few tens of nanometers across - the size of the smallest viruses and about 1,000 times smaller than the diameter of a human hair.
Hybrid Human Faces Could Populate Google Street View
