Human Cells have Electric Fields as Powerful as Lighting Bolts -A Galaxy Insight

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. But now using new nanotools, such as voltage-sensitive dyes, they can start to measure them at least. University of Michigan researchers led by chemistry professor Raoul Kopelman encapsulated voltage-sensitive dyes in polymer spheres just 30 nanometers in diameter. Kopelman has developed encapsulated voltage-sensitive dyes that aren't hydrophobic and can operate anywhere in the cell, rather than just in membranes.

Flowers get an electrifying buzz out of visiting bees - life - 21 February 2013 Plants could turn out to be one of the more chatty organisms. Recent studies have shown they can communicate with a surprising range of cues. Now it turns out they could be sending out electrical signals, too. As they fly through the air, bees – like all insects – acquire a positive electric charge. To test the idea, the team created artificial flowers, filling some with sucrose and others with quinine, a substance bees don't feed on. "That was the first hint that had us jumping up and down in the lab," says Robert. Next, his team looked at whether the bees were influenced by the shape of a flower's electric field, which is determined by the flower's shape. Ruthless evolution The researchers don't know exactly what information is contained in the flowers' electrical signals, but they speculate that flowers could evolve different shaped fields in their competition to attract pollinators. Of course, there may be a few cheaters out there that won't budge a millivolt when visited, he says.

Quantum 'weirdness' used by plants, animals - Technology & Science 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."

The Spice That Prevents Fluoride From Destroying Your Brain Fluoride is found everywhere today, from antibiotics to drinking water, no stick pans to toothpaste, making exposure inevitable. All the more reason why new research proving this common spice can prevent fluoride damage is so promising! Fluoride’s neurotoxicity has been the subject of academic debate for decades, and now a matter of increasingly impassioned controversy among the general public, as well. From ‘conspiracy theories’ about it being first used in drinking water in Russian and Nazi concentration camps to chemically lobotomize captives, to its now well-known IQ lowering properties, to its ability to enhance the calcification of the pineal gland – the traditional ‘seat of the soul’ – many around the world, and increasingly in the heavily fluoridated regions of the United States, are starting to organize at the local and statewide level to oust this ubiquitous toxicant from municipal drinking water. The study concluded, Discussion About the Author

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? Evolution is the new (old) computation...and we're about to take the reins. 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. What does this all mean?

Does DNA Emit Light? Dan Eden for 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. An example of this was a story of a giant human skeleton -- maybe 40 feet tall -- that was discovered by a Russian archaeological team. 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. Why Ultra-violet light? [Above] All vibrations of energy are part of the electro-magnetic spectrum. Photorepair Light inside the body

Unusual quantum effect discovered in earliest stages of photosynthesis Quantum physics and plant biology seem like two branches of science that could not be more different, but surprisingly they may in fact be intimately tied. Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory and the Notre Dame Radiation Laboratory at the University of Notre Dame used ultrafast spectroscopy to see what happens at the subatomic level during the very first stage of photosynthesis. While different species of plants, algae and bacteria have evolved a variety of different mechanisms to harvest light energy, they all share a feature known as a photosynthetic reaction center. These pigment molecules, or chromophores, are responsible for absorbing the energy carried by incoming light. "The behavior we were able to see at these very fast time scales implies a much more sophisticated mixing of electronic states," Tiede said. An article based on the study appeared online in the March 12 issue of the Proceedings of the National Academy of Sciences.

New wonder drug matches and kills all kinds of cancer — human testing starts 2014 Stanford researchers are on track to begin human trials of a potentially potent new weapon against cancer, and would-be participants are flooding in following the Post’s initial report on the discovery. The progress comes just two months after the groundbreaking study by Dr Irv Weissman, who developed an antibody that breaks down a cancer’s defense mechanisms in the body. A protein called CD47 tells the body not to “eat” the cancer, but the antibody developed by Dr Weissman blocks CD47 and frees up immune cells called macrophages — which can then engulf the deadly cells. The new research shows the miraculous macrophages effectively act as intelligence gatherers for the body, pointing out cancerous cells to cancer-fighting “killer T” cells. The T cells then “learn” to hunt down and attack the cancer, the researchers claim. The clinical implications of the process could be profound in the war on cancer. This turns them into a personalized cancer vaccine.

UCI, fellow chemists find a way to unboil eggs Irvine, Calif., Jan. 23, 2015 – UC Irvine and Australian chemists have figured out how to unboil egg whites – an innovation that could dramatically reduce costs for cancer treatments, food production and other segments of the $160 billion global biotechnology industry, according to findings published today in the journal ChemBioChem. “Yes, we have invented a way to unboil a hen egg,” said Gregory Weiss, UCI professor of chemistry and molecular biology & biochemistry. “In our paper, we describe a device for pulling apart tangled proteins and allowing them to refold. We start with egg whites boiled for 20 minutes at 90 degrees Celsius and return a key protein in the egg to working order.” Like many researchers, he has struggled to efficiently produce or recycle valuable molecular proteins that have a wide range of applications but which frequently “misfold” into structurally incorrect shapes when they are formed, rendering them useless.
