Quantum Biology and the Puzzle of Coherence One of the more exciting discoveries in biology in the last few years is the role that quantum effects seem to play in many living systems. The two most famous examples are in bird navigation, where the quantum zeno effect seems to help determine the direction of the Earth’s magnetic field, and in photosynthesis, where the way energy passes across giant protein matrices seems to depend on long-lasting quantum coherence. Despite the growing evidence in these cases, many physicists are uneasy, however. The problem is the issue of decoherence, how quickly quantum states can survive before they are overwhelmed by the hot, wet environment inside living things. According to conventional quantum calculations, these states should decay in the blink of an eye, so fast that they should not be able to play any role in biology. That’s led many physicists to assume something is wrong: either the measurements are faulty in some way or there is some undiscovered mechanism that prevents decoherence.
EINSTEIN and BLACK HOLES To understand how the universe was created, Einstein’s general theory of relativity needs to be unified with quantum mechanics. A Danish research team has come up with a theory of how this can be done. (Photo: Colourbox) Every single atom in your body was at one point created in the early universe, for example in supernova explosions – the first atoms being hydrogen atoms, which were presumably created soon after the Big Bang. This, at least, is the best explanation physicists have come up with so far. To understand the creation of our universe, we need to unify Einstein’s general theory of relativity and quantum mechanics. But now a research team from Copenhagen University’s Niels Bohr Institute has come up with a concrete framework for how this can be done. They are currently testing mathematical models which can gel the theories into one, and thereby contribute to our understanding of the Big Bang and black holes. The difference between gravity and quantum mechanics
Quantum tunnelling Quantum tunnelling or tunneling (see spelling differences) is the quantum mechanical phenomenon where a subatomic particle passes through a potential barrier. Quantum tunneling is not predicted by the laws of classical mechanics where surmounting a potential barrier requires enough potential energy. Quantum tunnelling plays an essential role in several physical phenomena, such as the nuclear fusion that occurs in main sequence stars like the Sun. It has important applications in the tunnel diode, quantum computing, and in the scanning tunnelling microscope. The effect was predicted in the early 20th century, and its acceptance as a general physical phenomenon came mid-century. Fundamental quantum mechanical concepts are central to this phenomenon, which makes quantum tunnelling one of the novel implications of quantum mechanics. History After attending a seminar by Gamow, Max Born recognised the generality of tunnelling. Introduction to the concept Applications or
TESLA Series Technologies | Synergistic Research The all new TESLA Series cables combine three revolutionary technologies based on the work of Nikola Tesla – the Tesla Tricon cable geometry, Zero Capacitance Active Shielding, and a proprietary Patent Pending conditioning process in a new line of cables that are smaller and more flexible than our previous models with significantly higher performance and value. TESLA Cables allow you to hear deeper into recordings with detail that’s transparent and non-fatiguing. In fact starting at the Accelerator interconnect and speaker cable level, TESLA Cables outperform every cable we have ever pitted them against regardless of price. These extraordinary cables represent a new benchmark by which all other cables can be measured and they do this with seemingly opposite strengths.

Human Cells have Electric Fields as Powerful as Lighting Bolts -A Galaxy Insight Using newly developed voltage-sensitive nanoparticles, researchers have found that the previously unknown electric fields inside of cells are as strong, or stronger, as those produced in lightning bolts. Previously, it has only been possible to measure electric fields across cell membranes, not within the main bulk of cells, so scientists didn't even know cells had an internal electric field. This discovery is a surprising twist for cell researchers. Scientists don't know what causes these incredibly strong fields or why they' are there. University of Michigan researchers led by chemistry professor Raoul Kopelman encapsulated voltage-sensitive dyes in polymer spheres just 30 nanometers in diameter. "They have developed a tool that allows you to look at cellular changes on a very local level," said Piotr Grodzinski, director of the National Cancer Institute Alliance for Nanotechnology in Cancer in Technology Review.

Quantum Biology INSIDE BLACK HOLES It is traditionally believed that our universe was formed approximately 13 billion years ago after the infamous Big Bang. But why did it happen and what was before it? Employees of Astro Space Center of the Physics Institute (ASC FIAN), Vladimir Lukash and Vladimir Strokov believe that the answer to this question can be a black hole. It is nearly impossible to get any reliable information about the black hole, because the force of its gravity is so high that even light particles - photons - cannot break from it. According to scientists, there is a zone inside the hole called singularity, where there is neither space nor time, and the density tends to infinity. It is assumed that the universe emerged from the singularity. Head of the Department of Theoretical Astrophysics ASC FIAN, Doctor of Physical and Mathematical Sciences Vladimir Lukash and his colleague Vladimir Strokov decided to simulate the situation that allows one to look at the singularity area and see what happens there.
Simulations back up theory that Universe is a hologram Artist's impression by Markus Gann/Shutterstock At a black hole, Albert Einstein's theory of gravity apparently clashes with quantum physics, but that conflict could be solved if the Universe were a holographic projection. A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection. In 1997, theoretical physicist Juan Maldacena proposed1 that an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings could be reinterpreted in terms of well-established physics. Maldacena's idea thrilled physicists because it offered a way to put the popular but still unproven theory of strings on solid footing — and because it solved apparent inconsistencies between quantum physics and Einstein's theory of gravity. “It seems to be a correct computation,” says Maldacena, who is now at the Institute for Advanced Study in Princeton, New Jersey and who did not contribute to the team's work.
Gravitational-wave finding causes 'spring cleaning' in physics Detlev van Ravenswaay/Science Photo Library Artist's rendering of 'bubble universes' within a greater multiverse — an idea that some experts say was bolstered with this week's discovery of gravitational waves. On 17 March, astronomer John Kovac of the Harvard-Smithsonian Center for Astrophysics presented long-awaited evidence of gravitational waves — ripples in the fabric of space — that originated from the Big Bang during a period of dramatic expansion known as inflation. By the time the Sun set that day in Cambridge, Massachusetts, the first paper detailing some of the discovery’s consequences had already been posted online1, by cosmologist David Marsh of the Perimeter Institute for Theoretical Physics in Waterloo, Canada, and his colleagues. Cosmologist Marc Kamionkowski of Johns Hopkins University in Baltimore, Maryland, agrees that some axion models no longer work, “because they require inflation to operate at a lower energy scale than the one indicated by BICEP2”. Linde agrees.
Earthing Research - EarthingInstitute.net Earthing Research The pursuit of scientific proof that contact with the Earth impacts human physiology and health began with Drs. Karol and Pawel Sokal in Poland and Clint Ober in the 1990s. The research that followed has produced fascinating evidence demonstrating that Earthing generates a powerful and positive shift in the electrical state of the body and the electrodynamics of blood, and restores natural self-healing and self-regulating mechanisms. We know that Earthing allows a transfer of electrons (the Earth’s natural, subtle energy) into the body. In the Earthing studies, as well as the feedback from thousands of individuals who have grounded themselves, we have consistent evidence of people whose pain was reduced. The institute hopes that evidence collected to date will inspire researchers with the financial resources to perform large studies to further clarify the benefits of Earthing.

RADIUS of BLACK HOLES Astronomers line three telescopes together to peer into a black hole'Giant telescope' allows team to measure jets leaving the 'event horizon' - and calculate the black hole's radius By Eddie Wrenn Published: 16:42 GMT, 1 October 2012 | Updated: 17:18 GMT, 2 October 2012 In astronomy, the point of no return is known as a black hole - a region in space where the pull of gravity is so strong that nothing - not even light - can escape. Now, an international team, led by researchers at MIT’s Haystack Observatory, has for the first time measured the radius of a black hole at the center of a distant galaxy - the closest distance at which matter can approach before being irretrievably pulled into the black hole. The scientists linked together radio dishes in Hawaii, Arizona and California to create a telescope array called the 'Event Horizon Telescope' (EHT) that can see details 2,000 times finer than what is visible to the Hubble Space Telescope.

Quantum black hole study opens bridge to another universe Physicists have long thought that the singularities associated with gravity (like the inside of a black hole) should vanish in a quantum theory of gravity. It now appears that this may indeed be the case. Researchers in Uruguay and Louisiana have just published a description of a quantum black hole using loop quantum gravity in which the predictions of physics-ending singularities vanish, and are replaced by bridges to another universe. View all Singularities, such as the infinitely strong crushing forces at the center of a black hole, in a physical theory are bad. Satellite orbiting Earth is guided by the spacetime curvature generated by the Earth's mass (Photo: NASA) General relativity has been summed up by the late John Wheeler's phrase: "Spacetime tells matter how to move, matter tells spacetime how to curve." The result is rather similar to a PA system on the verge of producing a feedback whistle. Let's follow this analogy a bit further. Easier said than done. Here's the problem.
Does DNA Emit Light? Dan Eden for viewzone.com An incredible story! I get lots of suggestions for stories, and I really appreciate them. But some of them are too good to be true. I had this same experience this week when I was sent an article where a Russian (again) scientist, Pjotr Garjajev, had managed to intercept communication from a DNA molecule in the form of ultraviolet photons -- light! But this was just the beginning. Dr. I tried to find a scientific journal that had this experiment. Fritz-Albert Popp thought he had discovered a cure for cancer. It was 1970, and Popp, a theoretical biophysicist at the University of Marburg in Germany, had been teaching radiology -- the interaction of electromagnetic (EM) radiation on biological systems. He'd been examining two almost identical molecules: benzo[a]pyrene, a polycyclic hydrocarbon known to be one of the most lethal carcinogens to humans, and its twin (save for a tiny alteration in its molecular makeup), benzo[e]pyrene.
