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. Researchers believe they may be able to learn more about disease states, such as cancer, by studying these minute, but powerful electric fields. University of Michigan researchers led by chemistry professor Raoul Kopelman encapsulated voltage-sensitive dyes in polymer spheres just 30 nanometers in diameter.

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. 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.

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,

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.”

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.

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.

Scientists Identify Gene Required for Nerve Regeneration A gene that is associated with regeneration of injured nerve cells has been identified by a team of researchers led by Prof Melissa Rolls of Penn State University. In fruit flies with two normal copies of the spastin gene, a team of scientists led by Prof Melissa Rolls of Penn State University found that severed axons were able to regenerate. However, in fruit flies with two or even only one abnormal spastin gene, the severed axons were not able to regenerate (Melissa Rolls / Penn State University) The team has found that a mutation in a single gene can entirely shut down the process by which axons – the parts of the nerve cell that are responsible for sending signals to other cells – regrow themselves after being cut or damaged. “We are hopeful that this discovery will open the door to new research related to spinal-cord and other neurological disorders in humans,” said Prof Rolls, who co-authored a paper published online in the journal Cell Reports.

New evidence that plants get their energy using quantum entanglement The fact that biological systems can exploit quantum effects is quite astounding. No it is not, not even remotely.There is literally no possible way that photosynthesis could take place without involving quantum physics. This particular exploit is really neat, of course, but far too much as been made of how mystical or ungraspable quantum physics is.
