¿Dónde estoy?
Un cuerpo sin alma,
un alma sin cuerpo.
Eso soy.
¿Qué soy?
No soy
Vacío, negro
-ausencia de luz-
Vacío negro,
sin densidad.
No hay luz.
No hay nada dentro de mí.
Nada.
No estoy en ninguna parte de mí.

Pobres Nukak Maku... que ridiculez el mundo!
El líder de una tribu nómada colombiana se suicida para que su pueblo regrese a la selva
20MINUTOS.ES. 26.10.2006 - 10:45h
Hace tiempo lloré, literalmente cuando vi esta noticia.
Más de la mitad de los nukak han muerto desde que la guerra de las drogas los expulsó de la selva (Revista Cromos)
Pertenece al que se considera último grupo aborigen nómada del mundo, los nukak .
La guerra de las drogas en Colombia los apartó de la selva y ahora viven en las afueras de una ciudad.
Desde 1988, casi la mitad de la población ha muerto y muchos sufren malnutrición.
Varias ONGs piden el regreso de los nukak a la selva colombiana.

Storage devices will be made of water

BOFFINS at the University of Pennsylvania, Drexel University and Harvard University have come up with an idea for a storage device which involves some nano-structures and a bit of water. Normally if you tip water over your computer, you msy get an electric shock and your computer will keel over and die, but the boffins have worked out that you can get stable ferroelectricity in nanostructures by terminating their surfaces with traces of water.
Jonathan Spanier, assistant professor of materials science and engineering at Drexel has successfully demonstrated the benefits of using water to stabilise memory bits in segments of oxide nanowires that are only about three billionths of a meter wide.
He said that he was particularly excited that water managed to make these wires 'remember' data. It means that if the technique was applied to store data, it would be possible to have more than 100,000 terabits per cubic centimetre.
According to the writers at uPenn.edu, this would mean an iPod sized device could store enough MP3 music to play for 300,000 years without repeating a song or enough DVD quality video to play movies for 10,000 years without repetition.
It would also mean that the RIAA would be suing anyone who runs a tap for owning a storage devise capable of holding pirated music and dragging goldfish, even dead goldfish, into court.

Water and Nanoelectronics Will Mix to Create Ultra-Dense Memory Storage Devices, Researchers Say

PHILADELPHIA -- Excessive moisture can typically wreak havoc on electronic devices, but now researchers have demonstrated that a little water can help create ultra-dense storage systems for computers and electronics.
A team of experimentalists and theorists at the University of Pennsylvania, Drexel University and Harvard University has proposed a new and surprisingly effective means of stabilizing and controlling ferroelectricity in nanostructures: terminating their surfaces with fragments of water. Ferroelectrics are technologically important "smart" materials for many applications because they have local dipoles, which can switch up and down to encode and store information. The team's work is reported in the April issue of Nano Letters.
"It is astonishing to see that a single wire of even a few atoms across can act as a stable and switchable dipole memory element," Jonathan Spanier, assistant professor of materials science and engineering at Drexel, said.
Spanier and his colleagues successfully demonstrated the benefits of using water to stabilize memory bits in segments of oxide nanowires that are only about 3 billionths of a meter wide.
"We have been interested in how water sticks to oxides," Alexie Kolpak, Penn graduate student in theoretical physical chemistry, said. "We are particularly excited that water is the key ingredient in making these wires 'remember' their state."
In this investigation, led by Hongkun Park of Harvard and Andrew Rappe of Penn, the researchers probed oxide nanowires individually to characterize the size-dependence of ferroelectricity and performed calculations and experiments to validate the presence of molecules on oxide surfaces and detail their important role in nanoscale ferroelectricity. Significantly, these results show that ferroelectric surfaces with water fragments or other molecules can stabilize ferroelectricity in smaller structures than previously thought.
Though a scheme for the dense arrangement and addressing of these nanowires remains to be developed, such an approach would enable a storage density of more than 100,000 terabits per cubic centimeter. If this memory density can be realized commercially, a device the size of an iPod nano could hold enough MP3 music to play for 300,000 years without repeating a song or enough DVD quality video to play movies for 10,000 years without repetition.

CUATRO MESES
Me dedico en este instante a lo único que puedo hacer: oir música.El ojo morado palpita, arde, pica, duele, cega. El dolor físico es absurdo además de la angustia que me da pensar que por distintas razones, llevo ya casi cuatro meses quieta. Primero el esquince de tobillo, después, la bronquitis, después la picadura infectada-nacido que me tiró a la cama, luego, bronquitis y ahora el ojo morado.
Todo al lado derecho.
Oigo música y escribo –que no es nada difícil para mí que escribo hasta con la luz apagada.
Me duele el ojo y me duele toda Maria José.
El ojo morado fue un juego. Estaba jugando con Matías, en el salón de baile, oyendo música y la falta de coordinación bilateral produjo un accidente sin grandes consecuencias en él; en realidad una medio llorada-risa que ninguno de los dos podía definir hasta que, cargando yo a Matías, y más preocupada por él que por mí (midiendo el dolor suyo por el mío) llegamos a la nevera para sacar hielo y, al ponerlo sobre la mesita de la cocina, él ya se había calmado y yo seguía con un dolor que aumentaba cada segundo. Revisé a Matías y tenía un pequeño rosadito en la frente.
Cogí dos toallitas y hielo y, ya que Matías no tuvo razón para usarla, sólo la mía contuvo el hielo que calmó un poco mi dolor que aún no para.
Ayer, en la Biblioteca Pública Piloto, había un homenaje a Felipe Ossa (librero de la Librería Nacional, a quien queremos debido a que mi mamá es, por lo general, la arquitecta de la Librería, hemos llegado a conocer y a disfrutar de él, sea en persona o por sus historias únicas. Yo tenía muchas ganas de ir (aunque la Piloto ya no tiene la misma connotación afectiva de cuando mi papá estaba vivo, por Felipe) y ya me había programado desde hacía días y lo había confirmado en la tarde con mi mamá.
Cuando sucedió el accidente intenté localizar a mi mamá -fue imposible pues el celular estaba descargado– para que le le mandara saludes a Felipe y le dijera por qué no iba.
Seguí poniéndome hielo. Matías, hermoso, me "daba vuelta" y me decía: "mami, te doy un besito en la nariz pacito para que te llegue al ojo" y me preguntaba, culpable, que por qué estaba así (tan hinchado).
Cuando Ade, mi hermana, llegó le dijo que él me había hecho eso. Lo abracé y le dije que no era culpa de él, que había sido un accidente. Se le notó la cara de descanso.
Está tan hermoso Matías... (esta foto la publico a petición de él: "mami, pero quiero que se vean los dos ojos, con la bola").Ya amaneció y estoy nuevamente inmovilizada, preguntándome qué es lo que me pasa con mi lado derecho y mis bronquios que no descansan desde hace cuatro meses.
