Here is a Science fair project presented by a girl in a secondary school in Sussex . In it she took filtered water and divided it into two parts. The first part she heated to boiling in a pan on the stove, and the second part she heated to boiling in a microwave. Then after cooling she used the water to water two identical plants to see if there would be any difference in the growth between the normal boiled water and the water boiled in a microwave. She was thinking that the structure or energy of the water may be compromised by microwave. As it turned out, even she was amazed at the difference, after the experiment which was repeated by her class mates a number of times and had the same result.
It has been known for some years that the problem with microwaved anything is not the radiation people used to worry about, it’s how it corrupts the DNA in the food so the body can not recognize it.
Microwaves don’t work different ways on different substances. Whatever you put into the microwave suffers the same destructive process. Microwaves agitate the molecules to move faster and faster. This movement causes friction which denatures the original make-up of the substance. It results in destroyed vitamins, minerals, proteins and generates the new stuff called radiolytic compounds, things that are not found in nature.
So the body wraps it in fat cells to protect itself from the dead food or it eliminates it fast. Think of all the Mothers heating up milk in these ‘Safe’ appliances. What about the nurse in Canada that warmed up blood for a transfusion patient and accidentally killed him when the blood went in dead. But the makers say it’s safe. But proof is in the pictures of living plants dying!

NO, YOU PIG-IGNORANT ASSWIPES.
SOME KID’S CLASS PROJECT IS NOT REAL SCIENTIFIC RESEARCH. YOU’VE HEARD OF “DOUBLE BLIND”, RIGHT? CALL ME WHEN IT’S PUBLISHED IN NATURE.

the structure or energy of the water

what the fuck does that even mean you realize that a water molecule is made up of three fucking atoms and if you rearrange it it isn’t water anymore and you would fucking notice

the problem with microwaved anything is not the radiation people used to worry about

Here is a handy diagram I drew of all the different types of radiation:

Microwaves != nuclear reactors, so calm your tits.

it’s how it corrupts the DNA in the food so the body can not recognize it

…do you understand what DNA is and how eating works? DNA is a jumble of protein nucleic acid in the middle of each cell and it tells the cells in that particular organism how to make more cells. Your body does not care about whether your food has any DNA in it or not. The chemicals it cares about are things like vitamins and sugars, as well as inorganic shit like salt.
(You can denature DNA by heating it or using chemicals like urea. It is like what happens when you fry an egg, which is basically a big glob of protein—the strands break apart and it looks like tiny white strings. Very cool.)

Microwaves agitate the molecules to move faster and faster.

I…just…that is the fucking definition of heat, whether you’re heating something over a flame or in a microwave or using the Sun. The difference is that microwaves mostly affect the water molecules in your food and they don’t need to use as much heat. Water boils at 100°C, which is just about as hot as water can get before it just turns into steam; but that’s like the lowest setting on your oven. Oven- or stove-cooked food tastes different partly because it uses higher temperatures and partly because heat is transferred in a different way.

This movement causes friction

That’s not what friction is.

It results in destroyed vitamins, minerals, proteins and generates the new stuff called radiolytic compounds, things that are not found in nature.

Let’s take these one at a time.
Vitamins are classified as water-soluble or fat-soluble. So cooking things in water will dissolve the water-soluble vitamins (C and all the B’s). Just plain heat doesn’t do that, so microwaving veggies—which keeps the water in—is actually a healthier option.
Proteins: Breaking the chemical bonds in proteins (denaturing) is a part of any cooking. However, denatured protein is still nutritious—that’s why you can meet your protein intake with foods like fried eggs and baked chicken.
Minerals are just chemical elements, like off the periodic table—sodium, iron, potassium. (Vitamins and proteins are very complex combinations of elements.)
Which brings me to the “radiolytic compound” bullshit. When you talk about breaking apart, say, iron—you’re talking about breaking down the iron atoms themselves. Which is a whole lot different than breaking the bonds between atoms. It takes hella radiation. You need shit like gamma rays—the OOOH SCARY NUCULAR radiation—which we’ve already established do not come from your microwave.

things that are not found in nature

What the shit does that even mean? You all know radioactive elements occur in nature, right? In rocks and also in living cells. That’s right, you have this radioactive kind of carbon INSIDE YOU. You get it by eating those delicious plants. We can tell how long ago something died by how much of it is left.
Tons of shit that occurs naturally is horribly bad for you. And tons of shit that never existed until we cooked it up is great for you—like the chemical compounds in a lot of medications.
PEOPLE WHO BELIEVE THIS SHIT ARE WHY CHILDHOOD DISEASES THAT CAUSED SERIOUS ILLNESSES AND/OR DEATH THAT WE NEARLY ERADICATED WITH VACCINES ARE NOW COMING BACK AND WHY CONSPIRACY THEORIST TWATS ARE ASKING CITY COUNCIL NOT TO FLUORIDATE THE WATER AND WHY GLOBAL WARMING WILL WRECK OUR FUCKING PLANET.

The bartender gives them both water because he is able to distinguish the boundary tones that dictate the grammatical function of homonyms in coda position as well as pragmatic context.

Chloroform is an organic compound with the chemical formula CHCl3.  It is also called trichloromethane, formyl trichloride, methane trichloride, methyl trichloride, and methenyl trichloride.  It has a strong, sweet odor.
Chloroform is found commonly in nature.  An estimated 90% of atmospheric chloroform is of natural origin.  It was first synthesized, using various procedures, by Justus von Liebig and Eugène Soubeiran (independent of one another) in 1831;  by Jean-Baptiste Dumas in 1835;  and by Henri Victor Regnault in the 1840s.  By the 1850s, it was mass-synthesized (dominantly using the Liebig method) for use as an industrial solvent and a reagent in organic synthesis.  In 1847, obsetrician James Young Simpson discovered its use as a general anesthetic in his quest to find a replacement for ether.  In 1848, John Snow developed an inhaler that regulated better the dosage of gaseous chloroform, and thus reduced the number of accidental deaths caused by its anesthetic use.  It was abandoned in the late 19th century-early 20th century in favor of less volatile anesthetics, due to chloroform’s documented tendency to cause fatal cardiac arrhythmia, or ‘sudden sniffer’s death’ as it is colloquially known (even with the assistance of Snow’s inhaler).
Chloroform was notably used in at least one experimental heat engine as a working fluid in lieu of steam.  Original prototypes utilized ether as an alternative, but chloroform replaced it due to its non-flammable nature (whereas ether is highly flammable).  These experiments emerged due to the misconception that a fluid with a lower boiling point than water, being easier to vaporize, would enable the construction of a more efficient engine.  (The reverse, as it turns out, is true.)  Exaggerated claims of the engine’s efficiency were made in an 1848 issue of Scientific American.  Besides this singular mention, it appears the chloroform engine was quickly abandoned.
It wouldn’t be long before chloroform’s potential criminal use was discovered.  Although it was utilized recreationally and for suicidal purposes almost immediately after its discovery, the first documented case of chloroform as a criminal tool did not occur until 1894, when Joseph Harris was charged with using it to rob people.  In 1901, chloroform was implicated in the murder of William Marsh Rice.  It was also used in 1991 in the asphyxiation murder of a sleeping woman.
In popular culture, chloroform is depicted as an agent applied to a rag, which is then applied to the face of a victim and held in place until they are rendered unconscious.  However, this is an urban legend and a cliche perpetuated by crime fiction authors;  it takes at least five minutes of inhaling an item soaked in chloroform to render a person unconscious.  Most crimes in which chloroform was a factor involved another chemical agent, such as alcohol or diazepam, or the victim was already unconscious/asleep when the soaked item was used to cover their nose and mouth.  (A fatal oral dose of chloroform, however, may be as small as 10ml (14.8g), causing respiratory or cardiac arrest.)
Due to murmurs of its alleged ability for instant incapacitation, the medical journal Lancet in 1865 offered a “permanent scientific reputation” to anyone who could demonstrate “instantaneous insensibility” using only chloroform.  No one earned the reputation.
With prolonged storage in the presence of oxygen, chloroform converts into phosgene, a colorless gas that gained infamy for its use as a chemical weapon during World War I.  Chloroform also metabolizes into phosgene in the human liver.
Ways to Manufacture Chloroform
Bleach contains sodium hypochlorite, which reacts with acetone, ethanol, and isopropyl alcohol to form chloroform, hydrochloric acid, and other dangerous chemicals.  For this reason, it is advised that you never mix bleach with anything else, including other cleaning agents, as accidental manufacture and exposure to chloroform can cause skin, lung, and eye irritation.  It is also a known carcinogen.
In industry, chloroform is manufactured by mixing heated chlorine with chloromethane or methane.  At 400-500 degrees Celsius, the compounds become more chlorinated, forming four chloromethanes (chloromethane, dichloromethane, chloroform, and carbon tetrachloride).  The chloroform is then separated through distillation.

Outer-site Art

 

Tokyo-based artist Makoto Azuma doesn’t appear to believe in doing things by halves. His latest installation looks at the universe, beyond Earth, as a site for appreciating beauty and art. Two pieces, a Japanese white pine bonsai known as the “Shiki 1”, and an untitled arrangement of orchids, hydrangeas, lilies and irises, were launched into the stratosphere last week in the Black Rock Desert, Nevada. This is part of project Exobotanica – Botanical Space Flight (see more pictures here), where Azuma heads a 10 person team, coupled with Sacramento-based JP Aerospace — “America’s Other Space Program”, a volunteer-based organization that constructs and sends vessels into orbit.

 

Azuma is interested in the beauty of organic movement in plants, and how this beauty would be suspended in space as a weightless environment. The objects themselves – the bonsai plant and the flower arrangement, have an almost uneasy juxtaposition in their nature. On the one hand, they are organic, Earth-bound items that send instant connotations to the viewer about the beauty of our natural world, yet both represent a natural world moulded by human hands – the miniaturised tree and the specifically arranged flowers. In the end, they can almost be seen less as art and more as specific examples of Earthly design; an amalgamation of human and mother nature’s architecture, broadcast to the universe beyond.

 

But equally as stunning is the documentary imagery itself, taken from orbit and brought back to Earth. Oh to see what those blossoms have seen!

EYE SEE YOU
Only short-wavelength light, with blue and green hues, penetrates deep underwater. So some fish native to those depths use fluorescent molecules in their tissues to display longer-wavelength colors such as red and orange. Researchers propose that the trait may have evolved to protect sensitive eye tissues, or it may be decorative, like the plumage on a parrot. In the photos, fish displaying this trait are shown under normal light (right) and under blue light that excites the red fluorescence in their tissues (left).
