Sociedades de insetos: mais evidências para a fórmula de sistemas da Matriz/DNA

terça-feira, janeiro 4th, 2011

O diagrama da Matriz referente ao estado de perfeito sistema fechado, um moto contínuo utópico mas que serve de unidade de medida para avaliar todos os outros sistemas naturais, e o qual quase foi alcançado na formação das galaxias, tentou ser reproduzido aqui levando insetos a construírem sistemas sociais nos seus moldes. Portanto estes sistemas são de interesse de estudos pela teoria da Matriz/DNA e por isso, nesta categoria “sistemas: vamos registrando noticias relacionadas como a abaixo (nossa primeira conclusão está no comentário que adicionamos no fim do artigo):

(PhysOrg.com) — Future queen or tireless toiler? A paper wasp’s destiny may lie in the antennal drumbeats of its caretaker.
 

Future queen or tireless toiler? A paper wasp’s destiny may lie in the antennal drumbeats of its caretaker.

While feeding their colony’s larvae, a paper wasp queen and other dominant females periodically beat their in a rhythmic pattern against the nest chambers, a behavior known as antennal drumming.

The drumming behavior is clearly audible even to human listeners and has been observed for decades, prompting numerous hypotheses about its purpose, says Robert Jeanne, a professor emeritus of entomology at the University of Wisconsin-Madison. Many have surmised that the drumming serves as a communication signal.

“It’s a very conspicuous behavior. More than once I’ve discovered nests by hearing this behavior first,” he says.

Jeanne and his colleagues have now linked antennal drumming to development of social caste in a native paper wasp, Polistes fuscatus. The new work is described in a study published in the Feb. 8 issue of by Jeanne, UW-Madison postdoctoral researcher Sainath Suryanarayanan and John Hermanson, an engineer at the USDA Forest Products Laboratory in Madison, Wis.

Paper wasp colonies, like many other , have distinct castes — workers, which build and maintain the nest and care for young, and gynes, which can become queens, lay eggs and establish new nests.

Both workers and gynes hatch from eggs laid by the colony’s queen, but gynes develop large stores of body fat and other nutrients to help them survive winter or other harsh conditions, start a new nest, and produce eggs. Workers have very little fat, generally cannot lay eggs and die off as the weather turns cold.

“The puzzle has been how the same egg, the same genome can give rise to two such divergent phenotypes,” says Suryanarayanan, who led the work as part of his doctoral studies.

Among honeybees, the key has been traced to the nutritional quality of the food fed to developing larvae: future queens receive the nutrient-rich “royal jelly,” while future workers receive stored pollen and nectar. However, there is no evidence that paper feed their young workers and gynes differently, he says.

Rather, the new work shows that exposure to simulated antennal drumming biases developing larvae toward the physiological characteristics of workers rather than gynes. The finding indicates that the wasps may use antennal drumming to drive developing larvae toward one caste or the other.

The researchers brought colonies into the lab and hooked up piezoelectric devices, designed by Hermanson, to the nests to produce vibrations that simulate antennal drumming. When they introduced the signal to late-season nests that would normally be producing gynes, the hatched wasps resembled workers instead, with much lower fat stores.

Suryanarayanan and Jeanne previously reported field studies that show antennal drumming is very frequent early in the season, when colonies are pumping out workers to expand and maintain the nest and take care of young. The behavior drops during the course of the season to nearly zero by late summer, the time when the reproductive wasps — males and future queens — are being reared.

“We think it initiates a biochemical signaling cascade of events,” Suryanarayanan says. “Larvae who receive this drumming may express a set of genes that is different from larvae who don’t, genes for proteins that relate to caste.” Some possibilities might include hormones, neurotransmitters or other small biologically active molecules, he adds.

Much is known about the effects of stressors, including mechanical stress or vibrations, on animal development and physiology. Intriguingly, one study found that young mice exposed to low-frequency vibrations developed less fat and more bone mass than other mice. But the wasp’s use of vibration to communicate with its own young sets it apart.

 “This is the first case we know of a mechanical vibratory signal that an animal has evolved to modulate the development of members of its own species,” says Jeanne.

These primitives social system are reproductions of systemic circuit of non-living ancestrals like astronomic and atoms systems. We can understand why and how the vibration is a inherited instinct that keeps the systemic circuity as a cascade of events, if we see the formula at the “The Universal Matrix of Natural Systems”. The queen performs the Function 1, which starts the flow of the circuity.

In Tiniest Computer Memory Ever, Researchers Successfully Store Data in Atomic Nuclei

By Rebecca Boyle Posted 12.17.2010 at 12:57 pm 8 Comments

Nuclear Spintronics This phosphorus-doped silicon chip was used to demonstrate nuclear spin memory. Researchers were able to store information for 112 seconds. Dane R. McCamey

Physicists have stored information for nearly two minutes inside the magnetic spins of atomic nuclei, producing the longest-lasting spintronic device yet and what could be the world’s tiniest computer memory.

There’s just one problem: the computer operates at -454 F (about 3.2 degrees K) and requires a magnetic field roughly 200,000 times more powerful than Earth’s.

Still, it’s a major advancement in spintronics, which involves storing data in the magnetic compasses of atomic particles. Usually, data is stored in the spin of electrons, but the memory lifetime is on the timescale of microseconds, according to the study, conducted by researchers in Australia and Utah and published today in the journal Science.

Instead, the researchers stored data in the longer-lived nucleus of an atom. D.R. McCamey and colleagues mapped the electronic spin of electrons orbiting phosphorus atoms that had been added to a silicon semiconductor. The team used near-terahertz electromagnetic waves to give the electrons a specific spin. Then they used FM-range radio waves to “write” the spin onto the phosphorus nuclei, as explained by the University of Utah.

After 112 seconds, the spin was mapped back onto an electron, to be electrically read out. The team used classical binary data (0 and 1) rather than quantum data. But the method could be used in conventional computers as well as quantum computers, according to Christopher Boehme, a University of Utah physics professor and senior author.

Two years ago, a different research group reported storing quantum data for two seconds within atomic nuclei, but they did not read it electronically, Boehme said. The longer time is more than adequate to create spintronic memory for computers, he said.

It’s effective because nuclei are less susceptible to temperature changes and interference from other electrons, McCamey said: “Its spin isn’t messed with by what’s going on in the clouds of electrons around the nucleus. Nuclei experience nearly perfect solitude.”

The next step would be figuring out how to accomplish the same task in higher temperatures and weaker magnetic fields, Boehme said.

¿Autoeditarse?
por Francisco José Súñer Iglesias

La autoedición siempre ha sido el último recurso del autor deseoso de verse en blanco sobre negro. Cuando las editoriales han rechazado repetidamente el manuscrito, y el hecho de verlo convertido en ese oscuro objeto del deseo bibliográfico es más fuerte que la necesaria prudencia, el autor se embarca en la aventura de convertirse en su propio editor.

No hablo de esas pequeñas tiradas que se hacen para «consumo interno» entre un reducido círculo de amigos y familiares. Quedan simpáticas y normalmente el autor ya es consciente de que la novela nunca pasará del aplauso de las abuelas y esos amigos que parecen ilustrados, pero no. Tampoco me refiero a los autores que se deciden por la difusión electrónica y gratuita de sus escritos. Ahí, además del grupo ya mencionado, entran quienes la consideran como una interesante práctica promocional. Hablo de la autoedición como opción comercial.

Particularmente no me parece el camino más adecuado. Si nadie entre los expertos consultados ha considerado adecuado publicar el manuscrito ¿de verdad cree el autor que va a conseguir algo por su cuenta? No se le puede negar el cariño que siente por su obra, ni la fe acumulada en ella al cabo de largas horas de trabajo, pero por lo pronto debería ser sintomático el hecho de que profesionales con experiencia lo hayan rechazado una y otra vez.

Las editoriales imponen un filtro. Puede que injusto, pero necesario porque la mayoría de los textos que se reciben son, directamente, ilegibles. Y eso lo digo con pleno conocimiento de causa, si bien no paso de fan-editor, y sin muchas ínfulas, también tengo que bregar con mi correspondiente parte del «pastel»

Si el pensamiento general es que se publica mucha basura, solo imaginar lo que se queda en el camino pone los pelos de punta. Hay una corriente de pensamiento que prácticamente exige que TODO esté disponible en las mismas condiciones que los textos trabajados por un equipo de profesionales (autor, editor, corrector) Eso no tiene sentido ni justificación, ni siquiera de cara al lector, que con mucho prefiere que alguien se haya encargado por él de hacer la criba. La cantidad de «exploradores» literarios está muy, muy, por debajo de las estimaciones de los autoeditores, y un simple examen de conciencia basta para comprobarlo. Hazte estas preguntas: ¿cuántas obras literarias sin «presentación» previa lees en proporción a las «presentadas»? ¿cuánta gente conoces que prefiera lanzarse a la aventura de lo desconocido antes que guiarse por lo oído y leído a terceros? El mero hecho de que estés leyendo este artículo, en esta web, casi responde la primera pregunta.

Una vez pasado el filtro, la relación entre el editor y el autor es muchísimo más enriquecedora de lo que se puede creer. Cualquier autor que haya tenido la suerte de caer en manos de un editor mínimamente competente sabe que, dejando el ego bien encerrado en el cajón de las novelas malas, su obra ganará en calidad. No hay mas que leer LA DANZA DE LA MUERTE y su versión sin cortes, APOCALIPSIS, de Stephen King, para comprobar cómo el editor llevaba razón cuando impuso recortes a la novela. Un editor puede enseñar muchísimo a un autor, hasta (sobre todo) en el tan fundamental como descuidado aspecto de la corrección ortotipográfica y de estilo. Pero para ello es esencial que el autor se olvide del orgullo, y que considere como condición esencial que alguien más allá de su círculo de fieles opine, y no necesariamente para alabarla hasta el empalago, de «su» novela.

Hasta ahí la parte creativa, pero eso es solo la primera fase. El editor es el profesional de cómo vender un libro. La contracultura al uso nos dice que un empresario ha de ser malvado por naturaleza. Si un editor hace negocio con los libros es que no puede ser bueno. ¿Por qué? El autor no tiene por qué saber nada del tema. El editor sabe a qué ferias y eventos (Frankfurt, Madrid, Guadalajara de México…) debe llevar el libro y CÓMO llevarlo para que alcance la mayor difusión. El editor sabe qué formato es el adecuado para el libro, qué tipo de papel y encuadernación ha de usarse (o su equivalente electrónico). El autor normalmente no tiene ni idea. Raramente su oficio tiene que ver con la imprenta, la distribución o la venta. Es bastante probable que fracase en cualquiera de esas tareas, si no en todas.

Descontando los escasos casos de éxito, que no por exitosos dejan de ser anecdóticos, triunfar en la aventura de la autoedición solo podría estar al alcance de autores con un cierto recorrido, que han demostrado su valía, y con una «marca» llamativa que ya inspira confianza. ¿Pero un desconocido? Si su obra no ha interesado a los expertos y profesionales del ramo, ¿por qué cree que va a conseguir el reconocimiento de los lectores?

Nikolas Kozloff é um jornalista sobre Amazonia e Brazil, que deve ser visto. 

http://www.nikolaskozloff.com/blog.htm

How could you think that the salvage espirit of Amazon Jungle leads us to a world vision that suggests never before thinkable models about cosmology,cellular systems,physics of atoms,the DNA as having ancestors being the matrix of astronomic systems, atoms systems, etc.? A world vision that now arribved to the conclusion that Light is the creator of Life and Universes, showing that a wave of light carries on the DNA code and the dynamics of life cycle?

The inspirations comes from some kind of salvage natural spirit,or from non-rational animals ways for perceiving nature, or from allunations produced by Amazon roots and herbs?

This world vision is being registered at a website called “The Universal Matrix/DNA of Natural Systems and Life’s Cycle” (theuniversalmatrix.com) by a Brazillian and American resident naturalist phylosopher that has lived seven years in the jungle.

If you are interested in this issue ( an unknown aspect of South American culture)after seeing the website (atualizad in Portuguese only, click “Artigos”) maybe writing an article about, my e-mail is austriak727@hotmail.com , Newark, New Jersey, and my only interest is that you could help me to divulgate this issue.
