Brain Waves Surge Moments Before Death
A study of seven terminally ill patients found identical surges in brain activity moments before death, providing what may be physiological evidence of "out of body" experiences reported by people who survive near-death ordeals. Doctors at George Washington University Medical Faculty Associates recorded brain activity of people dying from critical illnesses, such as cancer or heart attacks. Moments before death, the patients experienced a burst in brain wave activity, with the spikes occurring at the same time before death and at comparable intensity and duration. Writing in the October issue of the Journal of Palliative Medicine, the doctors theorize that the brain surges may be tied to widely reported near-death experiences which typically involve spiritual or religious attributes. At first, doctors thought the electrical surges picked up by electroencephalographs were caused by other machines or cell phones in the rooms of dying patients, lead author Lakhmir Chawla told Discovery News.
Human Cell Electric Fields Are As Powerful as Lighting Bolts -A Galaxy Classic
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. Posted by Rebecca Sato
Health Benefits of Mushrooms | Day Recipe
Mushrooms are valuable health food – low in calories, high in vegetable proteins, chitin, iron, zinc, fiber, essential amino acids, vitamins & minerals. Mushrooms also have a long history of use in Traditional Chinese Medicine. Their legendary effects on promoting good health and vitality and increasing your body’s adaptive abilities have been supported by recent studies. These studies suggest that Mushrooms are probiotic – they help our body strengthen itself and fight off illness by maintaining physiological homeostasis – restoring our bodies balance and natural resistance to disease. Agaricus Mushroom Agaricus is the most widely consumed mushroom in many countries, where it is regarded as a health food, due to its medicinal properties. Cordyceps Mushroom Cordyceps can be a powerful stimulant for macrophage activity, strengthening your immune system’s ability to fight against bacterial and viral infection. Maitake Mushroom Reishi Mushroom Reishi has been called an “immune potentiator.”
Brief Answers to Cosmic Questions
Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? Evolution of the Universe Did the Universe expand from a point? More about the Big Bang When they say "the universe is expanding," what exactly is expanding? Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? If you could suddenly freeze time everywhere in the universe, and magically survey all of creation, you would find galaxies extending out far beyond what we can see today. Does the term "universe" refer to space, or to the matter in it, or to both? Today, the situation is reversed. Discovering the properties of space remains one of the deepest and most important problems in modern science. Evolution of the Universe Did the Universe expand from a point? More about the Big Bang

Physicists always have a habit of taking the simplest example of any phenomenon and calling it "physics," leaving the more complicated examples to become the concern of other fields... "Science is the belief in the ignorance of experts. " "I can live with doubt and uncertainty and not knowing. "The first principle is that you must not fool yourself - and you are the easiest person to fool." "If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... "We cannot define anything precisely! "...far more marvelous is the truth than any artists of the past imagined it. (On pseudoscience) "...there is one feature I notice that is generally missing in 'cargo cult science'... "I'd hate to die twice.
