O espectacular hexágono de Saturno

NASA's Cassini Spacecraft Obtains Best Views of Saturn Hexagon

In Full View: Saturn's Streaming Hexagon This colorful view from NASA's Cassini mission is the highest-resolution view of the unique six-sided jet stream at Saturn's north pole known as "the hexagon." This movie, made from images obtained by Cassini's imaging cameras, is the first to show the hexagon in color filters, and the first movie to show a complete view from the north pole down to about 70 degrees north latitude.

NASA's Cassini spacecraft has obtained the highest-resolution movie yet of a unique six-sided jet stream, known as the hexagon, around Saturn's north pole.

This is the first hexagon movie of its kind, using color filters, and the first to show a complete view of the top of Saturn down to about 70 degrees latitude. Spanning about 20,000 miles (30,000 kilometers) across, the hexagon is a wavy jet stream of 200-mile-per-hour winds (about 322 kilometers per hour) with a massive, rotating storm at the center. There is no weather feature exactly, consistently like this anywhere else in the solar system.

"The hexagon is just a current of air, and weather features out there that share similarities to this are notoriously turbulent and unstable," said Andrew Ingersoll, a Cassini imaging team member at the California Institute of Technology in Pasadena. "A hurricane on Earth typically lasts a week, but this has been here for decades -- and who knows -- maybe centuries."

Weather patterns on Earth are interrupted when they encounter friction from landforms or ice caps. Scientists suspect the stability of the hexagon has something to do with the lack of solid landforms on Saturn, which is essentially a giant ball of gas.

Better views of the hexagon are available now because the sun began to illuminate its interior in late 2012. Cassini captured images of the hexagon over a 10-hour time span with high-resolution cameras, giving scientists a good look at the motion of cloud structures within.

Biofotões, Corpo humano e emissão de Luz


Olá!
Enquanto não publicamos o texto do mês, deixo estes artigos interessantes sobre Biofotões e a emissão de luz pelo corpo, seguido de texto do site para a divulgação do tema.
Texto científico aqui.
Namaste!


Do El País 1982:

El físico alemán Albert Popp constata la existencia de la radiación luminosa celular

 
El investigador alemán Fritz Albert Popp, profesor de Física en la Universidad de Marburgo (República Federal de Alemania), acaba de arrojar una nueva luz sobre un tema que apasiona tanto a médicos como a biólogos y físicos: la emisión de radiación luminosa por parte de las células animales y vegetales. El doctor Popp ha constatado recientemente la existencia de este proceso natural de los seres vivos, calificada de hipótesis hasta ahora, y ha puesto de manifiesto la gran importancia que ello supone para el tratamiento de numerosas enfermedades; entre ellas, el cáncer.
Desde el descubrimiento realizado por el científico ruso Alexander Gurvich, en 1923, acerca de la existencia de un tipo de radiación por medio de la cual las células se comunicaban entre sí, los biofísicos de todo el mundo han estado a la caza de las partículas y mecanismos implicados en este proceso. Gurvich, quien trabajó con cultivos celulares de plántulas de cebolla, observó que si se interponía un cristal de vidrio entre las células se producía una desincronización de sus divisiones reproductoras (mitosis); no así con un cristal de cuarzo. Lo que le llevó a pensar que existía una emisión de radiación electromagnética entre ellas, perteneciente a la banda de los rayos ultravioletas e implicada en un desconocido proceso informativo intercelular.Fue un compañero de Popp, del Laboratorio de Biofísica de la Universidad de Marburgo, Bernd Ruth, quien, hace ocho años, pareció dilucidar de una vez por todas la cuestión. Utilizando un multiplicador fotoelectrónico, aparato tan sensible que puede detectar la presencia de una luciérnaga a diez kilómetros de distancia, comprobó que realmente las células emitían luminosidad, aunque de ínfima intensidad (hecho del que, desde 1960, científicos rusos decían haber demostrado).
Ruth encontró, además, los portadores de dicha radiación: unas partículas a las que denominó biofotones. Y constató la excelente capacidad de las células sanas para emitirlas, detectarlas y acumularlas. Las objecciones surgieron esta vez ante la posibilidad de que esta irradiación fuera de origen térmico, ya que se sabe que todas las sustancias, animadas e inanimadas, emiten cierta radiación siempre que posean una temperatura superior al cero absoluto (-273,16 ºC). Esto es, precisamente, lo que el doctor Popp acaba de refutar, ya que la medición de la radiación celular resulta incomparablemente más potente que la producida por la temperatura.

El ritmo de una célula sana

Popp opina que este tipo de radiación se encuentra, efectivamente, al servicio de la comunicación celular, puesto que se trata de una emisión de tipo lasérico. Es decir, las células sanas no emiten ondas luminosas de forma caótica, sino rítmica y coherentemente (entendiendo por coherencia un parámetro indicador de la validez del intercambio de información en una comunicación), característica de los rayos láser.Ello supone un nuevo punto de vista para el concepto de enfermedad, puesto que las células sanas han demostrado ser excelentes acumuladores de fotones y poseen mayor capacidad para conservar su energía que cualquier otro acumulador técnicamente realizable.
Su muerte, sin embargo, hace que se pierda esta capacidad. Hecho comprobado al observarse un aumento cien veces superior de irradiación luminosa cuando ello sucede y su desaparición total al cabo de unas horas. Para Popp, dado que el deterioro de un sistema biológico, la enfermedad y la muerte implican la disminución de la coherencia y, por consiguiente, el aumento de la pérdida de información, la observación de la radiación de las células vivas contituiría un instrumento inapreciable para realizar diagnósticos prematuros.
Incluso piensa que los organismos enfermos podrían someterse a un tratamiento de coherencia, mediante la aplicación de un estímulo rítmico exterior, para recuperar el ritmo propio. Esta terapia podría ser, por ejemplo, el uso del láser infrarrojo a diodos, ya que científicos de la Universidad de Alma Atta (Unión Soviética) descubrieron en la década de los sesenta que la radiación de esta zona del espectro es, precisamente, una de las más importantes y mayoritarias emitidas por las células.
Otro punto interesante derivado de las investigaciones de este físico alemán se refiere a la concepción termodinámica de los sistemas biológicos. Se reconocía, hasta ahora, su capacidad de intercambiar no sólo energía con su entorno, sino también materia, por lo que son considerados, desde el punto de vista físico, sistemas abiertos, no conclusos. La reciente aportación de Popp, defendida hace años por el premio Nobel belga llya Prigogine, es que el ser vivo es, en realidad, el resultado de un complicado y permanente proceso de equilibrio entre las desviaciones más diversas de un estado aparentemente constante, así como que el grado de orden que puede alcanzar y mantener bien acotado por el punto a partir del cual la emisión de la radiación celular deja de ser de tipo lasérico, el denominado umbral láser.

Biophotons: The Human Body Emits, Communicates with, and is Made from Light

Tuesday, June 25th 2013 at 7:00 pm
Biophotons: The Human Body Emits, Communicates with, and is Made from Light
Increasingly science agrees with the poetry of direct human experience:  we are more than the atoms and molecules that make up our bodies, but beings of light as well. Biophotons are emitted by the human body, can be released through mental intention, and may modulate fundamental processes within cell-to-cell communication and DNA.
Nothing is more amazing than the highly improbable fact that we exist. We often ignore this fact, oblivious to the reality that instead of something there could be nothing at all, i.e. why is there a universe (poignantly aware of itself through us) and not some void completely unconscious of itself?
Consider that from light, air, water, basic minerals within the crust of the earth, and the at least 3 billion year old information contained within the nucleus of one diploid zygote cell, the human body is formed, and within that body a soul capable of at least trying to comprehend its bodily and spiritual origins.
Given the sheer insanity of our existential condition, and bodily incarnation as a whole, and considering that our earthly existence is partially formed from sunlight and requires the continual consumption of condensed sunlight in the form of food, it may not sound so farfetched that our body emits light.
Indeed, the human body emits biophotons, also known as ultraweak photon emissions (UPE), with a visibility 1,000 times lower than the sensitivity of our naked eye. While not visible to us, these particles of light (or waves, depending on how you are measuring them) are part of the visible electromagnetic spectrum (380-780 nm) and are detectable via sophisticated modern instrumentation.[1],[2]

The Physical and "Mental" Eye Emits Light

The eye itself, which is continually exposed to ambient powerful photons that pass through various ocular tissues, emit spontaneous and visible light-induced ultraweak photon emissions.[3] It has even been hypothesized that visible light induces delayed bioluminescence within the exposed eye tissue, providing an explanation for the origin of the negative afterimage.[4]
These light emissions have also been correlated with cerebral energy metabolism and oxidative stress within the mammalian brain.[5] [6] And yet, biophoton emissions are not necessarily epiphenomenal.  Bókkon's hypothesis suggests that photons released from chemical processes within the brain produce biophysical pictures during visual imagery, and a recent study found that when subjects actively imagined light in a very dark environment their intention produced significant increases in ultraweak photo emissions.[7]  This is consistent with an emerging view that biophotons are not solely cellular metabolic by-products, but rather, because biophoton intensity can be considerably higher inside cells than outside, it is possible for the mind to access this energy gradient to create intrinsic biophysical pictures during visual perception and imagery.[8]

The Human Eye Emits Light

Our Cells and DNA Use Biophotons To Store and Communicate Information

Apparently biophotons are used by the cells of many living organisms to communicate, which facilitates energy/information transfer that is several orders of magnitude faster than chemical diffusion. According to a 2010 study, "Cell to cell communication by biophotons have been demonstrated in plants, bacteria, animal neutriophil granulocytes and kidney cells."[9] Researchers were able to demonstrate that "...different spectral light stimulation (infrared, red, yellow, blue, green and white) at one end of the spinal sensory or motor nerve roots resulted in a significant increase in the biophotonic activity at the other end." Researchers interpreted their finding to suggest that "...light stimulation can generate biophotons that conduct along the neural fibers, probably as neural communication signals."
Even when we go down to the molecular level of our genome, DNA can be identified to be a source of biophoton emissions as well. One author proposes that DNA is so biophoton dependent that is has excimer laser-like properties, enabling it to exist in a stable state far from thermal equilibrium at threshold.[10]
Technically speaking a biophoton is an elementary particle or quantum of light of non-thermal origin in the visible and ultraviolet spectrum emitted from a biological system.   They are generally believed to be produced as a result of energy metabolism within our cells, or more formally as a "...by-product of biochemical reactions in which excited molecules are produced from bioenergetic processes that involves active oxygen species,"  [11]

The Body's Circadian Biophoton Output

Because the metabolism of the body changes in a circadian fashion, biophoton emissions also variate along the axis of diurnal time. [12]  Research has mapped out distinct anatomical locations within the body where biophoton emissions are stronger and weaker, depending on the time of the day:
Generally, the fluctuation in photon counts over the body was lower in the morning than in the afternoon. The thorax-abdomen region emitted lowest and most constantly. The upper extremities and the head region emitted most and increasingly over the day. Spectral analysis of low, intermediate and high emission from the superior frontal part of the right leg, the forehead and the palms in the sensitivity range of the photomultiplier showed the major spontaneous emission at 470-570 nm. The central palm area of hand emission showed a larger contribution of the 420-470 nm range in the spectrum of spontaneous emission from the hand in autumn/winter. The spectrum of delayed luminescence from the hand showed major emission in the same range as spontaneous emission.
The researchers concluded that "The spectral data suggest that measurements might well provide quantitative data on the individual pattern of peroxidative and anti-oxidative processes in vivo."

Meditation and Herbs Affect Biophoton Output

Research has found an oxidative stress-mediated difference in biophoton emission among mediators versus non-meditators. Those who meditate regularly tend to have lower ultra-weak photon emission (UPE, biophoton emission), which is believed to result from the lower level of free radical reactions occurring in their bodies. In one clinical study involving practitioners of transcendental meditation (TM) researchers found:
The lowest UPE intensities were observed in two subjects who regularly meditate. Spectral analysis of human UPE has suggested that ultra-weak emission is probably, at least in part, a reflection of free radical reactions in a living system. It has been documented that various physiologic and biochemical shifts follow the long-term practice of meditation and it is inferred that meditation may impact free radical activity.[13]
Interestingly, an herb well-known for its use in stress reduction (including inducing measurable declines in cortisol), and associated heightened oxidative stress, has been tested clinically in reducing the level of biophotons emitted in human subjects.  Known as rhodiola, a study published in 2009 in the journal Phytotherapeutic Research found that those who took the herb for 1 week has a significant decrease in photon emission in comparison with the placebo group.[14]

Human Skin May Capture Energy and Information from Sunlight

Perhaps most extraordinary of all is the possibility that our bodily surface contains cells capable of efficiently trapping the energy and information from ultraviolet radiation. A study published in the Journal of Photochemistry and Photobiology in 1993, titled, "Artificial sunlight irradiation induces ultraweak photon emission in human skin fibroblasts," discovered that when light from an artificial sunlight source was applied to fibroblasts from either normal subjects or with the condition xeroderma pigmentosum, characterized by deficient DNA repair mechanisms, it induced far higher emissions of ultraweak photons (10-20 times) in the xeroderma pigmentosum group.  The researchers concluded from this experiment that "These data suggest that xeroderma pigmentosum cells tend to lose the capacity of efficient storage of ultraweak photons, indicating the existence of an efficient intracellular photon trapping system within human cells."[15]  More recent research has also identified measurable differences in biophoton emission between normal and melanoma cells.[16]

Human Skin and Light

In a previous article, Does Skin Pigment Act Like A Natural Solar-Panel, we explored the role of melanin in converting ultraviolet light into metabolic energy:
Melanin is capable of transforming ultraviolet light energy into heat in a process known as "ultrafast internal conversion"; more than 99.9% of the absorbed UV radiation is transformed from potentially genotoxic (DNA-damaging) ultraviolet light into harmless heat.
If melanin can convert light into heat, could it not also transform UV radiation into other biologically/metabolically useful forms of energy? This may not seem so farfetched when one considers that even gamma radiation, which is highly toxic to most forms of life, is a source of sustenance for certain types of fungi and bacteria.

The Body's Biophoton Outputs Are Governed by Solar and Lunar Forces

It appears that modern science is only now coming to recognize the ability of the human body to receive and emit energy and information directly from the light given off from the Sun. [17]
There is also a growing realization that the Sun and Moon affect biophoton emissions through gravitational influences.  Recently, biophoton emissions from wheat seedlings in Germany and Brazil were found to be synchronized transcontinentally according to rhythms associated with the lunisolar tide.[18]  In fact, the lunisolar tidal force, to which the Sun contributes 30 % and the Moon 60 % of the combined gravitational acceleration, has been found to regulate a number of features of plant growth upon Earth.[19]

Intention Is a Living Force of Physiology

Even human intention itself, the so-called ghost in the machine, may have an empirical basis in biophotons.
A recent commentary published in the journal Investigacion clinica titled "Evidence about the power of intention" addressed this connection:
Intention is defined as a directed thought to perform a determined action. Thoughts targeted to an end can affect inanimate objects and practically all living things from unicellular organisms to human beings. The emission of light particles (biophotons) seems to be the mechanism through which an intention produces its effects. All living organisms emit a constant current of photons as a mean to direct instantaneous nonlocal signals from one part of the body to another and to the outside world. Biophotons are stored in the intracellular DNA. When the organism is sick changes in biophotons emissions are produced. Direct intention manifests itself as an electric and magnetic energy producing an ordered flux of photons. Our intentions seem to operate as highly coherent frequencies capable of changing the molecular structure of matter. For the intention to be effective it is necessary to choose the appropriate time. In fact, living beings are mutually synchronized and to the earth and its constant changes of magnetic energy. It has been shown that the energy of thought can also alter the environment. Hypnosis, stigmata phenomena and the placebo effect can also be considered as types of intention, as instructions to the brain during a particular state of consciousness. Cases of spontaneous cures or of remote healing of extremely ill patients represent instances of an exceedingly great intention to control diseases menacing our lives. The intention to heal as well as the beliefs of the sick person on the efficacy of the healing influences promote his healing. In conclusion, studies on thought and consciousness are emerging as fundamental aspects and not as mere epiphenomena that are rapidly leading to a profound change in the paradigms of Biology and Medicine.
So there you have it. Science increasingly agrees with direct human experience: we are more than the atoms and molecules of which we are composed, but beings that emit, communicate with, and are formed from light.

What is biophoton science?

Biophotons

It has been scientifically proven that every cell in the body emits more than 100,000 light impulses or photons per second. These light emissions, which are not only emitted by humans but by all living things, are called biophotons and have been found to be the steering mechanism behind all biochemical reactions.

Scientific research

Biophotons have been observed and measured using specialized equipment since the 1970s, starting with the pioneering studies of biophysicist Fritz-Albert Popp. Since that time over 30 peer-reviewed academic research papers on biophotons have been published in publicly indexed scientific journals.

Every biochemical reaction is preceded by an electromagnetic signal

In the classic models of chemistry and physics, light is emitted when an electron is “excited” to a higher energy state and then falls back down to a lower energy state, which occurs any time a chemical reaction takes place. Traditionally, biology and medicine have focused on the biochemical reactions between proteins, DNA, and other molecules within cells. However, a biophoton is always emitted before every biochemical reaction. Without the biophoton signal, there can be no chemical reaction; they are like a steering system for all the biochemistry that takes place in the body.

Communication of information between cells

The body uses biophotons as information packages to send signals from one point to another in much the same way that fiber-optic cables transmit signals using light. Biophotons carry information about the state of the body, because healthy cells, sick cells, tumor cells, and infectious viruses and bacteria have different light signals. Biophotons, like all photons, can form either a pattern of coherence, where individual light frequencies complement each other as in laser light, or chaos, where individual frequencies are disordered. These principles of biophotons form the basis for biontology.

Light is life

Human beings are essentially light beings. Medicine is grounded in the study of cadavers, dead tissue. But only living things emit light. Traditional medicine tries to correct a chemical imbalance in the body by adding more chemicals. This may or may not have the desired effect on one symptom, but it will inevitably add stress elsewhere in the body. By contrast, when biophotons are made available to the body using the Chiren instrument, the body will use only what it needs to neutralize chaotic signals and thus restore health.

A verdadeira Casa Hobbit Sustentável 3

 Agricultor inglês constrói "casa verde" por 150 libras / + de 150€ / 500 reais - e esta, sim, uma verdadeira casa Hobbit!

Casa pronta por 500 reais

Acredite: inglês faz construção completa com materiais descartados e 150 libras. Entenda como é possível

Acredite: essa casa inteira foi construída por pouco mais de 500 reais (Foto: Divulgação)

Para a maior parte das pessoas, o desejo de construir uma casa parece distante devido aos preços altíssimos de terreno, mão de obra e materiais. Mas o fazendeiro inglês Michael Buck provou ser possível tornar este sonho realidade, usando métodos e recursos pouco convencionais. Ele ergueu a moradia em sua propriedade com apenas 150 libras, o equivalente a pouco mais de 500 reais, sem a ajuda de mais ninguém. Para economizar, foram usados recursos descartados por outras pessoas ou simplesmente tirados da natureza. As paredes, por exemplo, são feitas de uma mistura de areia, argila, palha, água e terra. Foram oito meses de obra, sem nenhuma ferramenta – Buck fez tudo com as próprias mãos.

Com um orçamento tão apertado, o resultado é um pouco rústico. O teto é feito de palha, o piso de madeira foi resgatado de uma casa em demolição e os vidros das janelas vieram de um caminhão abandonado. Não há eletricidade, gás ou água encanada. Também não há sistema de aquecimento, o que poderia ser um problema no inverno europeu. Mas, segundo Buck, as grossas paredes impedem o frio de entrar e o teto é forrado por peles de carneiro. O fogão é a lenha e a luz vem somente de velas e lamparinas. São 28 m², com espaço para apenas um morador. Pode parecer arcaico demais para algumas pessoas, mas pensando no preço total, pode até valer a pena abrir mão de alguns confortos em nome da casa própria.

How to build a Hobbit house: A step-by-step guide to the £150 cottage built only from natural and reclaimed materials

  • Ever wondered how to build a fully functioning cottage for £150?
By Steve Bird
|

This week, the Mail reported how smallholder Michael Buck built a cottage on his land in Oxfordshire for just £150 using only local, natural and reclaimed materials. Mr Buck, a 59-year-old former art teacher, didn’t use any power tools to build the 300 sq ft house, which has no mains electricity, gas or water.
‘A house does not have to cost the Earth — you only need earth to build it,’ he explained.
STEVE BIRD explains how he did it . . .

Walls

Michael Buck and his friends first mashed up or ‘poddled’ a wet mud and straw mixture — known as cob — stamping barefoot on it on a large sheet made from the skin of an old trampoline found in a skip.
‘Poddling with the feet is very important,’ he says. ‘Being barefoot is far more efficient than wearing boots to mix it. It used to be done by cattle. It’s a wonderful sensation as it squidges between your toes.’

The straw mixed into the cob came from a nearby horse yard and cost £150 — the only money spent on the building project.
The water added to the cob mixture came from a well Mr Buck had dug, and the sand and clay came from the soil dug out for the foundations.
The cob was then shaped into bricks and left to dry before being used to build the walls.
The walls rose 4in each day of building. Mr Buck then used a large knife to smooth them into shape. The whole process took four months.

Ceiling

The ceiling inside is made from wattle and daub — a framework of woven sticks and mud-based plaster — and insulated with sheep’s wool donated by a local farmer.

Roof

Timber for the roof was taken from poplar trees in a nearby wood.
The roof structure runs through the top of the walls and up to a crest. Mr Buck taught himself to thatch, using long straw wheat grown by a local thatcher and reed found at Duke’s Cut, a waterway that connects the Oxford Canal with the River Thames.
He carried it to the house in 10ft bundles to avoid a carbon footprint. The thatch is held in place by intertwined sticks of local hazel.

Mattress

Sheep's wool stuffed into a duvet was used to make a mattress for the bed on the wooden mezzanine.

Flooring

The floorboards are made from reclaimed wood salvaged after the local Woolworths store in Oxford city centre closed down.

Lighting

Alcoves were moulded into the interior walls so candles could be used to light the building.
Cob houses are almost fireproof because so little wood is used. The density of the walls, usually around 2ft thick, ensures the house is well insulated.

Chimney

This was made of cob bricks and topped with broken tiles found around the site to prevent rain coming down it.

The house itself is heated with a wood-burning stove.

Bathtub and sink

Hanging outside is a large, metal bowl that can be filled with water from an ancient nearby spring. The bowl serves as a sink, bath tub and washbasin.

Windows

A lorry windscreen found in a rubbish tip was fitted as one window.

Three discarded wooden windows from the same tip were turned upside down so the rotten lower sills became the top sills.
The glass and frames were fitted into the walls and gothic-style windows set in the cob mix.

Foundations

The site had to be on ground with the ideal soil to form the basis of the mixture used in the ancient ‘cob’ building style — where bricks are made from a combination of earth, sand, clay, straw and water.
The technique is believed to date back to prehistoric times and is still common in the Middle East and Africa.

Too much clay in the soil and the cob bricks will become brittle and fracture; too little and they will crumble. Luckily, the soil in Mr Buck’s smallholding contains the perfect amount of clay.
He dug the foundations a foot deep to get to the ‘subsoil’, which he set aside to make the cob mixture. Then he created foundations from large stones taken from a neighbour’s dilapidated wall, adding some of the cob mixture as a form of cement.

Plaster

The outer layer of the wall was plastered with a smoother type of cob mixture. It included crushed-up bullrush heads from a local stream and cow dung from a nearby dairy to add some texture to the mixture.
The names of the three cows — Marigold, Crystal and Mist — which contributed are inscribed on the wall of the cottage.

Paint

The walls inside and out were finished with ‘Ali’, a cross between plaster and paint which is made from plant resin, clay and chalk, which Mr Buck collected from the Chiltern Hills, and flour that he ground himself on his farm.

Kitchen

The marble kitchen worktop and the woodburning stove were donated by Mr Buck’s sister during the renovation of her Dorset home.
Some poplar branches are built into the walls of the kitchen, from which pots and pans can be hung.

Outside loo

The lavatory is a ‘composting toilet’ that uses sawdust and moss to conceal and break down waste.
It’s also a loo with a view — of the beautiful, rolling Oxfordshire countryside.
