Reducing CO2...

Climate Lab

With a series of papers published in chemistry and chemical engineering journals, researchers from the Georgia Institute of Technology have advanced the case for extracting carbon dioxide directly from the air using newly-developed adsorbent materials.



The technique might initially be used to supply carbon dioxide for such industrial applications as fuel production from algae or enhanced oil recovery. But the method could later be used to supplement the capture of CO2 from power plant flue gases as part of efforts to reduce concentrations of the atmospheric warming chemical.



In a detailed economic feasibility study, the researchers projected that a CO2 removal unit the size of an ocean shipping container could extract approximately a thousand tons of the gas per year with operating costs of approximately $100 per ton. The researchers also reported on advances in adsorbent materials for selectively capturing carbon dioxide.

As much as I want to "stand up and cheer": technology has never been the issue. Do we have the political will to carry out - in this climate (pun intended) - such an audacious enterprise? Capturing CO2 from the air could mean things like: jobs for those suitably prepared. But, for those invested heavily in the science or the lobby pro/con climate change, it announces [to me] an inevitable fight, that in our effort to score "sound bite points," that by the time any compromise is reached, we all in the end may lose.

Mott Transistors...

Physics World - MottFET

Ideal Transistor

An ideal transistor would be a total insulator in the off state and a perfect conductor in the on state. Therefore, an important measure of the quality of a transistor is the ratio of the on current to the off current. However, with a standard field-effect transistor (FET), this change in conductivity is influenced by only a thin layer close to where the current flows between gate and drain. This limits the ratio of on current to off current that can be achieved.

 

Scientists have suggested that it might be possible to improve this ratio by exploiting Mott insulators in transistors. Mott insulators are materials that should behave as metals according to conventional band theories but that act as insulators under certain conditions owing to quantum-mechanical correlations between neighbouring electrons. For reasons that are complex and not entirely understood, however, sudden phase transitions can be induced between the insulating state and the metallic state. Among other things, this metal–insulator transition can be induced by an electric field. While the gate voltage in an ordinary transistor simply modulates the resistance of a semiconductor, the gate voltage in a Mott transistor could turn an insulator into a metal.

Curiousity...

NASA Mars Science Laboratory

Today (25 July 2012), the Mars Science Laboratory's terminal descent sensor is being checked out in preparation for Curiosity’s entry, descent and landing. The sensor is a radar system that is mounted on MSL's descent stage. Following separation of MSL's heat shield at an altitude of approximately 5 miles (8 kilometers) and a velocity of approximately 280 mph (125 meters per second), the sensor begins collecting data on the spacecraft's velocity and altitude in preparation for landing.

Sometimes, I think we forget we're still exploring deep space, with the eventual goal of manned missions to at least Mars for starters.

Some proposed ideas I've heard in the past: terraforming the Martian atmosphere with - smog, of all things - to warm it up a bit for human habitation, an ironic positive effect of warming a planet, i.e. if we can control it.

Franken-Jelly...

Title from the article. Sometimes these things write themselves. Smiley


Krystnell A. Storr, ScienceNOW: Now Frankenstein can have a pet jellyfish. A team of scientists has taken the heart cells of a rat, arranged them on a piece of rubbery silicon, added a jolt of electricity, and created a “Franken-jelly.” Just like a real jellyfish, the artificial jelly swims around by pumping water in and out of its bell-shaped body. Researchers hope the advance can someday help engineers design better artificial hearts and other muscular organs.

"One small step for man..." can be kind of gross! Probably not going to be one of my wife's favorite postings (ironically born in the Chinese year of the rat).

I'm a brother on some quiet Batman Sh@t!

Batwing DC Comics Unveils a Black Batman

Bat Wing character courtesy of DC Comics

I will call 911 on you on the low to preserve discreet information gathering or directly act if the situation is too hot to wait for police to arrive.

This is the new Black male citizenship paradigm I  ( and others ) practice and promote. It's the antidote to thug addiction intravenously
pumped into brothers minds by adults and (un) popular culture. I know jails are overcrowded but so are morgues with chocolate klansmen's only gift tot he community!

My contribution to our embattled community is a brother they can trust to advise them on safety and the long hard grind called seeking success without being a criminal.

When it comes to glacial police/community relations here in New Orleans and nationally the logical question is, "  can brothers who are against crime help NOPD? "

Hmmm?

" Yes " in theory.

" Maybe " in application.

Black men commit most of our street crime.  Reasonable observers would gather that uniting police and Black men opposing street crime is a no-brainer.

Not quite.

I have relationships with officers as do other anti crime brothers. Such scattered informal associations aside there is no formal coalition specifically uniting Black men with the police ( my Brothers & Badges Together model comes to mind, hint hint lol ). http://moveonup.ning.com/profiles/blogs/brothers-badges-together 

Again, most New Orleans street crime is a majority Black male affair. Getting Black men and cops on the same team isn't a " racist " response- it's realist.

Either we as a society see Black men as more than suspects ( unless employed by law enforcement agencies, etc ) or we don't.

Keeping anti crime brothers at arms length makes them wonder if liberal accusations about police being eternally biased are true?

I'd like to see Black male/police relations evolve to resemble a real world version of what Adam West's Batman enjoyed on his famed TV show.



It's a looong shot but worth the work I and others in this chocolate Klansmen era are making because there is no other decent choice!

All we have is the public safety miracle of all time waiting in the wings if we pull this off!
Surprised smile

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.

Sally K. Ride (Ph.D.)

NASA Astronaut (former)

PERSONAL DATA: Born May 26, 1951, in Los Angeles, California. Her mother, Joyce Ride, resides in Pasadena, California. Her father, Dale B. Ride, is deceased. She enjoys tennis (having been an instructor and having achieved national ranking as a junior), running, volleyball, softball & stamp collecting.



EDUCATION: Graduated from Westlake High School, Los Angeles, California, in 1968; received from Stanford University a bachelor of science in Physics and a bachelor of arts in English in 1973, and master of science and doctorate degrees in Physics in 1975 and 1978, respectively.



EXPERIENCE: Dr. Ride was selected as an astronaut candidate by NASA in January 1978. In August 1979, she completed a 1-year training and evaluation period, making her eligible for assignment as a mission specialist on future Space Shuttle flight crews. She subsequently performed as an on-orbit capsule communicator (CAPCOM) on the STS-2 and STS-3 missions.

She was one of the examples to young women of matriculating into STEM careers. I recall a country-western song dedicated to her. She died after a 17-month battle with pancreatic cancer. She was a physicist, an astronaut, a pioneer and a professor. She will be missed.

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?

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.

Aftermath...

Henry David Thoreau

I recall my father reading either the Winston-Salem Journel or the Sentinel (in those days, there were two daily papers - morning and evening).

"It's a crying shame," he said, holding the paper.

I saw what he was speaking of: a young man's (at the time, about my age) photo graced the front page; one-half of the page, wordy article. His parents, to encourage scholarship, paid him $10 per "A" he made. According to the reporting, he had made straight A's since kindergarten until at that time his most recent report card...

...he had one "B." His first ever.
 

The article reported, he reasoned his parents would pay him for the other A's he'd made. To his surprise, they gave him zero!
 

He responded by committing suicide. It was a sad, brutal loss.
 

The thought of such a violent, self-inflicted reaction to an otherwise excellent report card had my father saying: mmph!
 

I'd recently read Disciplined Minds by Jeff Schmidt, recalling the chapter in which some graduate students that had not passed their qualifier (an exam given usually after all coursework is completed, and before one is allowed to continue research in their field of study) resorted to violence against faculty, committees and associated people with which they had issue with. I reference a descriptive entry on Dr. Marcella Wilson's web site:
 
While pursuing my doctorate, I experienced panic attacks, depression, insomnia and phobias. There was a point were I was just really sad and in pain. It’s hard to explain to someone why you are so freaked out or why you are depressed all the time about school. It’s just a really emotional, unstable, high-pressure situation that you have no control over and no one else is going through.
 
Her lamented entry: "please don't let James Holmes be a PhD student."
 
 
I thought about this entry, the carnage wrought, and the possibility it had a genesis; a cause for this horrid effect. I really hope my speculation isn't the raison d'etre.
 
"Most men lead lives of quiet desperation and go to the grave with the song still in them." Henry David Thoreau

 

Graduate students are intellectually curious; not omniscient. They are human, and many quite young.

 
Like the young man that did such a rash act thirty-nine years ago and recent tragic events in Aurora, Colorado, previous academic successes may not prepare fragile self-esteems for not passing a final, getting a paper rejected from a prestigious journal; told to leave a program before completion of coursework or research; dismissal from a doctoral program; failure as feedback; setback as setup.
 
Learning from failure: it is a skill. The same that allowed Edison to fail time and againuntil finally...insomnia for most of the western world. Einstein's "Miracle Year" was while working in a German patent office with a pencil, several pieces of paper, and a handy wastebasket. In a win-at-all-cost culture, little is appreciated about persistence, moving forward, coming up with a "plan B."

It is a skill we could all spare to learn.

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!

The three captured and reprogrammed Brelac Reploids have proved their worth to the Protectorate in a fierce battle against the powerful cybernetic weapon Succubus, developed by traitorous Dr. Fenlow. The Reploids, commissioned to form a special unit known as the Silencers under the jurisdiction of the military’s Central Intelligence Division, are back on Maseklos Prime, working at menial jobs while the CID keeps a close eye on them. That changes when President Drennan is almost killed in a bizarre assassination attempt.

Colin McKenzie and his team are ordered to uncover whoever’s behind the assassination attempt and to find and destroy the frightening weapons responsible for the horrible death and destruction at the President’s last election campaign address. After the first attempt on the President’s life, it’s certain more are sure to follow.

Meanwhile, Colin remains curious and wary about his dark past as a Vendetta operative formerly working against the Protectorate. The more he learns about his previous life, the less he likes it. Even more worrisome is the odd dreams he’s been having.

As Colin, Diane, and Kelly chase leads in their case, they realize they may be up against unstoppable weapons – but they are the Protectorate’s only hope.

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.

Rosie Took Your Job...

When you just give love
And never get love
You'd better let love depart
I know it so
And yet I know
I can't get you out of my heart

You
Made me leave my happy home
You took my love and now you're gone
Since I fell for you


Lenny Welch (should hear it sung by Al Jarreau!)

In our economy, many of the jobs most resistant to automation are those with the least economic value. Just consider the diversity of tasks, unpredictable terrains, and specialized tools that a landscaper confronts in a single day. No robot is intelligent enough to perform this $8-an-hour work.


But what about a robot remotely controlled by a low-wage foreign worker?


Hollywood has been imagining the technologies we would need. Jake Sully, the wheelchair-bound protagonist in James Cameron's Avatar, goes to work saving a distant planet via a wireless connection to a remote body. He interacts with others, learns new skills, and even gets married—all while his "real" body is lying on a slab, miles away.

 

As the article alludes, it's no longer science fiction!

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?
