The Spooky World Of Quantum Biology

The Spooky World Of Quantum Biology
Michael Garfield The new science of quantum biology is teaching us about how the actual behavior of evolution is governed by disconcertingly spooky processes – time travel being one of them. Will quantum computation finally be realized by biomimicry, in organic systems? One hundred and fifty years ago, paleontologist Thomas Henry Huxley (an autodidact and philosopher who coined the term “agnostic” and was known as “Darwin’s Bulldog” for his passionate defense of natural selection) asserted that humankind would eventually take the processes of evolution into our own hands. The premise is simple. Quantum computation, a science still in its infancy, promises swiftness and efficiency vastly superior to anything possible with conventional silicon chips. It’s a promising avenue for people with big plans for strong AI or virtual reality. This is one of the reasons that many scientists have considered quantum biology both unlikely and unscientific. What does this all mean? Related:  Quantum Playground

Scientists stop the ageing process (ABC News in Science) Clean bill of health: Scientists have shown that clearing damaged protein from the liver helps stop age decline in the organ (Source: iStockphoto) Scientists have stopped the ageing process in an entire organ for the first time, a study released today says. Published in today’s online edition of Nature Medicine, researchers at the Albert Einstein College of Medicine at Yeshiva University in New York City also say the older organs function as well as they did when the host animal was younger. The researchers, led by Associate Professor Ana Maria Cuervo, blocked the ageing process in mice livers by stopping the build-up of harmful proteins inside the organ’s cells. As people age their cells become less efficient at getting rid of damaged protein resulting in a build-up of toxic material that is especially pronounced in Alzheimer’s, Parkinson’s and other neurodegenerative disorders. By contrast, the livers of normal mice in a control group began to fail. Read on… Like this: Like Loading...

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.

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.

National Center for Biotechnology Information 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.

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.

Effet Baldwin Un article de Wikipédia, l'encyclopédie libre. L'effet Baldwin est un corollaire à la théorie de l'évolution mise de l'avant en 1896 dans un livre intitulé Un nouveau facteur en évolution par James Mark Baldwin, qui propose un mécanisme de sélection spécifique sur les capacités d'apprentissage. Selon cette théorie, le comportement durable d'un individu ou d'un groupe influence sa capacité d'apprentissage et ne serait pas limité aux seuls facteurs génétiques. Démonstration[modifier | modifier le code] Par exemple, imaginons des oiseaux qui doivent faire face à un nouveau prédateur. La tolérance du lactose chez les humains est souvent prise comme exemple pour illustrer cette théorie. Cette hypothèse a été et reste controversée en biologie.

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.

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. Why Ultra-violet light? Photorepair

Fossil suggests new hominid species: Stone Age cavemen 'Red deer people' discovered in China 'Red deer people' lived 14,500-11,500 years ago in AsiaPreviously thought that homo sapiens had continent to themselves'Highly unusual' mixture of ancient and modern - could be new speciesCould also be relic of early migration out of Africa which died out By Rob Waugh Published: 15:00 GMT, 14 March 2012 | Updated: 09:27 GMT, 16 March 2012 Four Stone Age people found in caves in China could be a entirely new species of humanoid - and the discovery 'opens a new chapter' in the history of evolution, say archaeologists. The fossils, found in two caves, belong to a previously unknown Stone Age people and have a 'highly unusual' mixture of ancient and modern features. Named the 'Red Deer people' because of the animals they hunted and dating from between 14,500 to 11,500 years ago, they are the youngest humanoid fossils to be found in Asia. Previously it had been thought that early humans had little competition in the continent. But the new find suggests this may not have been the case.

BIRD: QUANTUM ENTENGLEMENT Birds like the European robin have an internal compass which appears to make use of a phenomenon called quantum entanglement. ((Vasily Fedosenko/Reuters)) Bird navigation, plant photosynthesis and the human sense of smell all represent ways living things appear to exploit the oddities of quantum physics, scientists are finding. Quantum mechanics is the branch of physics dealing with the strange behaviour of very tiny things like elementary particles and atoms, and is extremely different from the physics that humans experience every day. "Down at that level, everything is pretty darn weird," Seth Lloyd said before giving a lecture about quantum aspects of biology Wednesday evening in Waterloo, Ont. "Electrons can be in two places in once, or five places at once, or a thousand places at once. "When things get bigger, certainly on the scale of human beings or even at the scale of bacteria, then this kind of quantum weirdness tends to go away."

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.
