Pores are Pores...

A snapshot of a helical stack of macryocycles generated in the computer simulation: anl.gov

Scientists have overcome key design hurdles to expand the potential uses of nanopores and nanotubes. The creation of smart nanotubes with selective mass transport opens up a wider range of applications for water purification, chemical separation and fighting disease.

 

Nanopores and their rolled up version, nanotubes, consist of atoms bonded to each other in a hexagonal pattern to create an array of nanometer-scale openings or channels. This structure creates a filter that can be sized to select which molecules and ions pass into drinking water or into a cell. The same filter technique can limit the release of chemical by-products from industrial processes.

Quantum Dots and Cells...

From the article:

Physics Central

Quantum Dots

The study of quantum dots began in the 1980s. Quantum dots are very small amounts of semiconductor material (nanoparticles) whose size affects the allowed energy levels of the material. The electrons of the material usually reside in the lowest band of energy levels called the valence band. When the electron absorbs energy it is excited to a higher band of energy levels, levels called the conduction band, leaving behind an empty spot known as a hole. When the electron returns to the lower valence energy level it emits energy. How far apart the valence band and conduction band are depends on the size of the particle. The size of the particle controls what is known as the confinement energy, Figure 1. This means that the size of the particle can be used to control the different types of light the particles absorb and emit. Quantum dots have been created that absorb ultraviolet light and emit all of the colors of the rainbow depending on their size, rather than just what it is made of.

Quantum Dots and Cells

How does the quantum dot make a neuron fire? When a quantum dot is excited by light shining on it, it becomes polarized so that one part of the material is more positive and the other is more negative. This in turn sets up an electric field, which can interact with a neuron or other cell of interest. How strong that interaction is depends on how close the polarized quantum dot is to the cell. The closer it is, the stronger the interaction. The strength of the interaction also depends on the type of ion channel on the cell membrane. If the field set up by the quantum dot is strong enough, it can cause the ion channels to open and a transfer of ions out of and into the cell. For a neuron, this is "firing" the neuron or switching it on.

I'm trying to get away from vendor lock-ins, which includes the kindle. I want to be able to have access to my e-books locally not just in the cloud. I want to be able to use any variation of software or device to read my favorite sci-fi and fantasy books. The Ideal file format would be .epub. I have begun my search for a viable replacement for Amazon's kindle book store. The problem is that none of my favorite titles from the folks here are on these new sites? What's going on people? What gives? How many of you make your books available to more than just people with a Amazon or Barnes & Noble account? I really would love to continue reading great stories from you all, but I won't continue to buy my books from Amazon. Here are some sites I'm going to; kobobooks.com ,ebooks.com , and epubbooks.com. I hope to see your publishings there.

when are we in the future?

I have struggled my whole life to get a livable wage, secure the american dream and a decent retirement. Things have "went south" as they say. Was thinking of my dependency on all the systems and materials promoted my whole life long to make retirement as comfortable as when I had a good job. Then I started talking to ones a tad bit ahead of me and ones retired for a while, I am no longer optimistic about retirement. I am actually thinking about home scale garden plots, solar energy, wind energy, greenhouses, micro-farming, urban villages, all the ways to use technology to sustain life without sharecropping on the "grid". Supermarkets sell engineered and prepared foods to our bad health so that the healthcare industry is booming. The media is so mind-bending and mind-blending today, an indigenous culture is become an odd throwback. Jobs today require so much education only the poor can afford to ignore it. Don't worry, in the future we will have figured it all out so that every person can push the button. Er, ah, what's does this button do?

Cures and Caveats...

"Nanozyme": IEEE Spectrum

Researchers at the University of Florida (UF) have developed a nanoparticle that has shown 100 percent effectiveness in eradicating the hepatitis C virus in laboratory testing.

That sounds good, right? I do admit, I kind of bristle at claims of 100% efficiency, since in nature...that's supposed to be unachievable.

Of course, this is a long way from becoming a treatment anytime soon. A major caveat is that the use of nanotreatments for the targeting and destroying of abnormal cells like cancer cells is always problematic since those cells are “still us”...meaning we've got to have an "off" button for these critters! They might be a little too efficient.

So too, ignorance is not only bliss, it's easier than sifting through research that we're only mildly interested in. A "Google search" is about the BTUs we're willing to expend to understand (I'm not claiming expertise either, just healthy curiousity).

The author would like to retire the phrase "nanobot," as pointed out some of humankind will imagine Matrix Armageddon and a future of gray goo!

McKenzie Files. Book 1

The United Protectorate is under attack by the reptilian race known as the Brelac. The Brelac’s bloodthirsty onslaught brings forth the creation of the genetically engineered Humanoid weapons known as Reploids. These Reploids are the perfect weapon. They are the identical copies of real Humans that have been captured, killed, cloned, embedded with powerful psionic based abilities, and programmed to kill for the Brelac. They are untraceable as they blend into Human society.

Colin McKenzie is a second generation Reploid planted in the Protectorate military. When he turns on his commanding officer in an attempt to protect a shipwrecked band of Brelac soldiers, he is captured and reprogrammed along with two other arrested Reploids to serve the government that they were created to destroy.

A dark alliance between the Brelac and the separatist organization Vendetta looms over the Protectorate. The balance is upset when the traitorous Doctor Howard Fenlow, the scientist who is the very creator of the Reploids, manages to produce a weapon powerful enough to bring the Protectorate to it’s knees.

And there are only three that can stop it.

Our beloved comic book culture, as fans and for some. superhero theme activists, was used as a back drop to commit mass murder inside an Aurora Colorado movie premier of ” the Dark Knight Rises. “

Americans and world citizens who love this medium should look deeply into unfolding events and resolve to use one of its core values, individual vigilance to enhance public safety, to help people better secure what’s always been society’s soft under belly: theaters; malls; stores, eateries, etc.

Members of what media calls ” the real life superhero ( RLSH ) ” now have a golden opportunity to put aside petty squabbles in the face of a masked assault embodying the worst villainy of fact and fiction. Their use of superhero imagery can assume new seriousness in wake of this tragedy.

The Free World is being tested these days. From domestic crime to foreign terrorism free people are being battered by angry dissidents and worse. Those who enjoy comic books unbridled freedom and the few who even take this to the streets should unite to pump new life into tired appeals about being vigilant in public.

Whether this shooter is a loner or part of a plot our beloved comic book culture nonetheless has preached awareness against sudden evil from its inception. We ( meaning fans and activists ) shouldn’t go spastic and stage embarrassing fan boy pr exercises or misguided vigilantism as clumsy attempts to calm a frightened populace.

Using our beloved comic book culture as fans and activists to creatively high light the need for real life vigilance will be more than enough.

Our fictional heroes and heroines once again have shown us the way.

Whether we use their example to make horrible facts like this movie massacre history remains to be seen.

My thoughts and prayers are with the victims; their families and nations wondering if anywhere is safe anymore?

It was all the rage after a year of sweating it out with jobs and kids. Taking a vacation was a right of spring, especially after the ultra cold winter and blistering summer. Seems a waste to dwell on all this now. The sky is permanently etched by clouds and gray, greenery has receded like the hairline of a young man whose genes betrayed his good looks. People have left the cities for the endless shanty towns that connect them. A simpler life we all thought. What we got was chaos and disrepair.

They were all over the city, quonset huts on stilts, no windows, no apparent door. Mega-tek used to be an on-line video retailer. People still wanted theater experience but with mistrust and terrorism we avoid the old dark palaces and crowds. Mega-tek devised these self sustained video huts, you rent the key and help yourself to an eye-full and a mind-full. Mega-tek is a huge, self sustained complex in the city. They have access to every video footage on the planet. At least that's what I heard. No one goes to the city anymore, who's running the show? I don't know.

I found a key while rummaging for coupons, that's todays currency. The key is a coin shaped disc about the size of a quarter and twice as thick. Has the logo and instructions in texting script. Walk under the unit, stand on the spot. The place is on the edge of town, somewhat desolate. I stand on the spot beneath it's stoic form, a small light greets me. I watch an overhead trapdoor slide away and the earth at my feet raises to meet it. Needless to say I am scared. I come up into a ring of lounges surrounded by a ring of screens.

I sit and the screens burst into life, cartoon like instruction, commercials, offerings of syn-food refreshments. I just cried out, 'what happened to us?' All went dead at first as if putting all kidding aside. Then one by one each screen took it's turn retailing history. I don't know how long I was in there. I was OK but out side things were worse, it seems. Maybe it was because of all I saw. Some virtual vacation I said. I took out the coin looked at it again, it read, 'toss it for someone else to find.' I can't go back, I've been changed...................This story clip inspired by this equipment storage unit construction picture off the net.

Old sketch from old 'knowtbook' of a livingroom suite that could apply to this story.

container living development

I was looking at pictures of Africa they don't show you in the media. There are some mighty fine cities and large. I have only seen on TV the degradation and despair and military and why is every African leader who isn't pushing democracy a dictator? Anyway, when I see the big cities I want to go there and bask in the place.

I look at the enticing real estate offerings and realize it is kind of sick. With all the shambles and poverty for rural Africans, why does the escape from that equal the ostentatious display of wealth as if they read an ad, "now you too can have your own plantation, servants and live a little higher on the hog"....? I mean here is few limits you can do anything you wish. Of course I had a little nation building drummed into me in college, the utopian novel, black power and umoja ngoma (not by the school, of course).

I fell into the idea of using cargo containers as dwelling spaces. They resemble the corrugated shanty you see all over Africa. The modern container users seem not to prefer to alter them much. So when I see a single container home in contrast to surrounding homes they look quaint and ultra modern. In mass they look like a shanty town. I thought how can I change them so that an endless variety of configurations could be realized. Join them together with quonset huts and grain silos was the answer.

My first thought was not to mimic the western idea of housing as a standard. Since the glut of people live in less than that standard dwelling. Also something about how African cultures do things differently. So I strayed away from large personal spaces that compromised the communal space. If you have a big bedroom it takes away from the living room space. I ask why does every person need a personal apartment (bed, bath, kitchenette) in the house. I'm not saying every person gets a cubby hole and a mattress (a cell). My realization is that Africans respect the communal living more than of western folk.

I think about functional parts, bathroom, kitchen, lighting, utilities and open reconfigurable space. The cargo container becomes a basic unit, easy to set up, remove, and to alter with quonset arches and silo curves spanning spaces, breaking up straight walls, etc. Perhaps it is a little more compact than we would like. These parts are pre-manufactured and require less altering to surround space. I live in a house with nice rooms made small with overstuffed furniture. It is comfortable to the behind but looks cramped and small to the eyes. A lot of space is unused to be filled with junk.

Instead of down grading the typical western idea of a house, I am looking at upgrading the sheet steel shanty (hut), into a high tech dwelling unit or at least a more flexible way to enclose space. So, if you peruse my photos and see the dwelling unit concepts you have some idea where I am going with this line of thought.

Battleship: Col. Gadson Stole the Show

Col. Gregory D. Gadson stole the show in "Battleship". Gadson played Lieutenant Colonel Mick Canales a double amputee in physical therapy when the film opens. We meet him because he is a plot device for the love interest in the film showing that she is a three dimensional character rather than just a pretty face. However, he is necessary for her part in the battle to be plausible. His acting was strong, powerful, riveting, and left me wanting more. I researched Gadson on IMDB.com to find he is an active duty military officer and 'wounded warrior'. He was featured in the documentary "Wounded Warriors' Resilience" http://www.imdb.com/title/tt2097945/. I'm sure he is busy with his military duties but it would be great to see him in more films.

Fuel Cells!...

Department of Energy

A new approach to an established fuel will be the focus of research, development and maybe production with the help of NASA's Kennedy Space Center in Florida.

The company, based in Britain, has formulated a way to store hydrogen safely in tiny pellets that still allow the fuel to be burned in an engine. [NASA] Kennedy, which handles huge amounts of the explosive gas regularly as part of its rocket work, is being enlisted to help the company overcome a couple technological hurdles.

If the work pays off, engines all over the world could run on hydrogen, which burns clean, producing no greenhouse gases.

All Call For Suggestions

As many of you know, my Darkside Universe of novels, seven total planned, is centered around the premise that black folks have been secretly living on the backside of the moon since before Neil Armstrong set foot there.

What I'm in the process of doing now is writing a story in that universe from the perspective of a black man, living in American, observing the country's response to the "Discovery."

Where I think you all may help is if you wanted to take the time to write a short piece detailing how your "character" would have responded to the discovery.

So, what I'm looking to do is create a story, written by a group of contributors and submit it as a tale written by various personalities here on BSFS.

If nothing else, I would love to hear your opinions and ideas, everything is on the table.

Here's the beginning of the story's intro:

    Scott was born in 1955.  The average house cost $10,950. The cost of a new car was $2,000. Disneyland opens in California.  Ray Kroc began the McDonalds restaurant chain. Rosa Parks was arrested in Montgomery, Alabama, setting off the American Civil Rights Movement. And, fourteen year-old Emmett Till is murdered in Money, Mississippi for allegedly disrespecting a white woman. It was quite a year.
    He was a middle-aged black man of 46 when the country discovered that African Americans had been living on the moon since a handful of years after his birth, years before Neil Armstrong set foot on the surface.
    He lived through an unpopular war in Southeast Asia that ended in ignominy, the assassinations of President John F. Kennedy, the Reverend Martin Luther King, Jr., John’s brother Bobby. Malcolm X, and a host of others, for no better reason than what they said and did angered someone enough to kill.
    He watched as blacks were battered and bruised by fire hose and baton, set upon by vicious dogs, and killed for no other reason than the color of their skin giving license to others for such deadly, and inhumane, treatment.
    And, throughout his entire life, he observed how an entire industry persecuted, distorted and lied about the humanity of an entire race of people because whites needed a foil in their desperate need to cling to sociological, political and financial power over all persons colored. There was no love in his soul for the fictional tellings of a moneyed, corporate media.
    But all that changed when a CIA spy satellite saw unmistakable signs of life on the moon’s surface.  At first the US government tried to hide the fact, but too many people at NASA, Jet Propulsion Laboratories, and the Pentagon had seen the real-time download of images from the satellite for them to remain secret for long.  In fact, it wasn’t more than an hour before the country was informed that the satellite had recorded signs of habitation on the moon.
    In a belated effort to forestall panic and further rampant speculation, the President of the United States was forced to make an statement in an effort to calm the citizenry, to try to convey that this new circumstance was one that wasn’t a threat to the nation, and that whatever the challenge, the United States of America would meet it head on, and persevere.
    Right.  How does that old joke go: “Want to make God laugh? Tell him your plans!”
   

Thank you for your consideration.

Satyendra Nath Bose...



WIKIPEDIA: Satyendra Nath Bose FRS[1] (Bengali: সত্যেন্দ্র নাথ বসু Shottendronath Boshū, IPA: [ʃot̪ːend̪ronat̪ʰ boʃu]; 1 January 1894 – 4 February 1974) was an Indian physicist specializing in mathematical physics. He was born in Kolkata, then spelt Calcutta. He is best known for his work on quantum mechanics in the early 1920s, providing the foundation for Bose–Einstein statistics and the theory of the Bose–Einstein condensate. A Fellow of the Royal Society, he was awarded India's second highest civilian award, the Padma Vibhushan in 1954 by the Government of India.

 

The class of particles that obey Bose-Einstein statistics, bosons, was named after him by Paul Dirac.

 

A self-taught scholar and a polyglot (mastery of multiple languages), he had a wide range of interests in varied fields including physics, mathematics, chemistry, biology, mineralogy, philosophy, arts, literature and music. He served on many research and development committees in independent India.


A "mistake" leading to Bose-Einstein Statistics:

The reason Bose's "mistake" produced accurate results was that since photons are indistinguishable from each other, one cannot treat any two photons having equal energy as being two distinct identifiable photons. By analogy, if in an alternate universe coins were to behave like photons and other bosons, the probability of producing two heads would indeed be one-third (tail-head = head-tail). Bose's "error" is now called Bose–Einstein statistics. This result derived by Bose laid the foundation of quantum statistics, as acknowledged by Einstein and Dirac.

 

Velocity-distribution data of a gas of rubidium atoms, confirming the discovery of a new phase of matter, the Bose–Einstein condensate... Einstein adopted the idea and extended it to atoms. This led to the prediction of the existence of phenomena which became known as Bose-Einstein condensate, a dense collection of bosons (which are particles with integer spin, named after Bose), which was demonstrated to exist by experiment in 1995.

Heroes should be recognized, and acknowledged.Smiley

Enjoying rereading "The God Particle" by Leon Lederman. Had it since '93.

Sadly, it was in it the Superconducting Supercollider in Waxahatchie, Texas (there is such a place), where Lederman suggested as "the mother of all colliders" where we were supposed to discover the Higgs...oh, well! Smiley

Fiction and Science...

 

Homer Hickam's Amazon page

 


Bypasses are devices that allow some people to dash from point A to point B very fast while other people dash from point B to point A very fast. People living at point C, being a point directly in between, are often given to wonder what's so great about point A that so many people from point B are so keen to get there, and what's so great about point B that so many people from point A are so keen to get there. They often wish that people would just once and for all work out where the hell they wanted to be.”

 


Douglas Adams, The Hitchhiker's Guide to the Galaxy

 


“Man is an artifact designed for space travel. He is not designed to remain in his present biologic state any more than a tadpole is designed to remain a tadpole.”

 

 


“Science fiction is the most important literature in the history of the world, because it's the history of ideas, the history of our civilization birthing itself. ...Science fiction is central to everything we've ever done, and people who make fun of science fiction writers don't know what they're talking about.”

The Wrangling Begins...

Higgs Announcement at CERN

 




We have found it – now we have to work out exactly what "it" is. That neatly sums up the thoughts of many physicists at CERN yesterday as they began to absorb the announcement that the Large Hadron Collider (LHC) had discovered a Higgs boson – or at least something like a Higgs. CERN's director general Rolf-Dieter Heuer was very careful to describe the new particle, which has a mass of about 125 GeV/c2, as a "fundamental scalar boson". However, even the scalar part of that description – which indicates that the particle has zero spin – has not been completely nailed down.

 


The Scientific Method is a thought process, an accepted means of constantly questions itself in discoveries and published findings. It can be somewhat off-putting to the general public, used to definitive statements and cock-sureness (at least advertised by their political leaders). Although, I don't know if it's the scientists' fault (as Physics Today opines) more than we've become something our brains weren't designed for nor evolution intended: an entertainment culture addicted to instant gratification. What doesn't come easy to understand in seconds is quickly discarded instead of effort made to master. The Matrix was our undoing...
