Streams of sound are now all you need to make objects dance in the air and combine. A levitation device is the first to use high-frequency sound waves to bring together floating particles and liquid droplets. In principle, the technique could even levitate a person or animal – although it’s not strong enough yet.
For now, such hands-free control could be used to study chemical reactions in extreme environments, to move hazardous materials and to simulate the low-gravity environment of space. At 24 kilohertz, the waves are too high-pitched to be audible to humans – but can be heard by some animals, including cats, bats and mice.
Other levitation methods use magnets or electrical fields, making mag-lev trains – and even levitating frogs – possible. But in these cases, the levitated objects must have particular magnetic or electrical properties.
Acoustic levitation imposes no such constraints. It can, in principle, float anything, says Dimos Poulikakos of the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland.
A sound wave is a pressure wave that produces a force and so has the potential to counteract gravity. To float things using sound, you need to ensure the force remains constant in a particular point in space.
This has been done previously, by using speakers or other resonators to fire pressure waves upwards and bounce them off a reflector. The original waves and their reflections then combine to create a standing wave, with a series of stationary "nodes" that stay put even as the wave oscillates.
If the standing wave has the right frequency, the force at these nodes exactly cancels gravity – and anything trapped there hovers in place.
"Scientists at Argonne National Laboratory have discovered a way to use sound waves to levitate individual droplets of solutions containing different pharmaceuticals. While the connection between levitation and drug development may not be immediately apparent, a special relationship emerges at the molecular level."
The Aeon of Horus is Ending and the Elites are Nervous as their Icons are Dying 2014 04 18
I predict there is going to be a huge resurgence of interest in European indigenous spiritual traditions from Norse to Celtic/Gaelic to Slavic and so on. Millions of Europeans are going to realise that we are the victims of Christianity and New Age garbage. Their bastardised Kabbalah, the psychic force used by Crowley and the elites to cement his Aeon ...
Easter - Christian or Pagan? 2014 04 18
Contrary to popular belief, Easter does not represent the "historical" crucifixion and resurrection of Jesus Christ. In reality, the gospel tale reflects the annual "crossification" of the sun through the vernal equinox (Spring), at which time the sun is "resurrected," as the day begins to become longer than the night.
Rather than being a "Christian" holiday, Easter celebrations date back ...
Man-Made Blood Might Be Used in Transfusions by 2016 2014 04 18 Researchers in the U.K. have created the first man-made red blood cells of high enough quality to be introduced into the human body
The premise of the HBO show and book series True Blood revolves around a technological breakthrough: scientists figure out how to synthesize artificial human blood, which, as an ample new source of non-human food, allows vampires to "come ...
The Trials of the Cherokee Were Reflected In Their Skulls 2014 04 18
Researchers from North Carolina State University and the University of Tennessee have found that environmental stressors – from the Trail of Tears to the Civil War – led to significant changes in the shape of skulls in the eastern and western bands of the Cherokee people.
The findings highlight the role of environmental factors in shaping our physical characteristics.
Our Fears May Be Shaped by Ancestral Trauma 2014 04 18
Last December, an unsettling Nature Neuroscience study found that mice who were taught to associate the smell of cherry blossoms with pain produced offspring who feared the smell of cherry blossoms, even if they had never been exposed to it before. We knew that the process was epigenetic—that it was not hard-wired in the permanent genetic structure of the mouse—but ...
