Sustainability Edges Closer
“To fully understand how the energy-transfer system in photosynthesis works, you can’t just study the spatial landscape of these pigment-protein complexes, you also need to study the electronic energy landscape. This has been a challenge because the electronic energy landscape is not confined to a single molecule but is spread out over an entire system of molecules,” Fleming said. “Our new 2D electronic spectroscopy technique has enabled us to move beyond the imaging of structures and to start imaging functions. This makes it possible for us to examine the crucial aspects of the energy-transfer system that enable it to work the way it does.

Bugs and the Brain
- Mental illnesses once thought to be the result of neurological or psychological defects may be caused by viral or microbial infections.
- The strongest evidence links schizophrenia to prenatal influenza infection; pregnant women who become ill with the flu are more likely to give birth to children who will develop schizophrenia.
- The body’s immune reaction, rather than the infections themselves, may be to blame for the resulting brain damage and psychiatric symptoms.
- Understanding the relation between infections and psychiatric disorders may someday allow us to prevent mental illness using drugs or vaccines.
No doubt there's resistance but...Doctors have known for many years that microbes such as syphilis and Streptococcus can, if left untreated, lead to serious psychiatric problems. Now a growing number of scientists are proposing that microbes are to blame for several mental illnesses once thought to have neurological or psychological defects at their roots. The strongest evidence pertains to schizophrenia, but autism, bipolar disorder and obsessive-compulsive disorder have also been linked to bacterial, viral or parasitic infections in utero, in childhood or in maturity. Some of these infections can directly affect the brain, whereas others might trigger immune reactions that interfere with brain development or perhaps even attack our own brain cells in an autoimmune mistake.

As stated before in BRT, solutions are in the lab able to deal with climate change and sustainability. The question about scaling this tech to real world levels and the will to make it happen must be answered if we are to survive as a viable species on planet Earth.
Picturing to Learn
The funneling process is the key to which colors the pigments select. The complex of molecules at the reaction center can perform chemical reactions only if it receives a red photon or the equivalent amount of energy in some other form. To take advantage of blue photons, the antenna pigments work in concert to convert the high energy (from blue photons) to a lower energy (redder), like a series of step-down transformers that reduces the 100,000 volts of electric power lines to the 120 or 240 volts of a wall outlet. The process begins when a blue photon hits a blue-absorbing pigment and energizes one of the electrons in the molecule. When that electron drops back down to its original state, it releases this energy—but because of energy losses to heat and vibrations, it releases less energy than it absorbed.
The pigment molecule releases its energy not in the form of another photon but in the form of an electrical interaction with another pigment molecule that is able to absorb energy at that lower level. This pigment, in turn, releases an even lower amount of energy, and so the process continues until the original blue photon energy has been downgraded to red. The array of pigments can also convert cyan, green or yellow to red. The reaction center, as the receiving end of the cascade, adapts to absorb the lowest-energy available photons. On our planet’s surface, red photons are both the most abundant and the lowest energy within the visible spectrum.
Because photosynthesis is a quantum mechanical process able to function under different star types (Click on the above graphic to see Sciam's take on this.), the chances of finding life on other worlds should not be a big deal save for the fact man will finally know that he is not alone.
When this process is combined with chemosynthesis, the possibility of life existing on other worlds really takes off as the need for sunlight disappears and, as Jeff Goldblum says in Jurassic Park, Life Finds a way.
For other BRT blurbs on this subject, The Goldilocks Zone and Life Finds a Way indicates that thinking earth is the only place where life resides is somewhat far fetched to say the least.
Regarding intelligent life, I agree with Stephen Hawking in that it's rare but not beyond the realm of possibility because if it is, then nature has paid a cruel joke on this universe by having us as it's sole representative of intelligent life.

Music of the Spheres
Well it seems the ancient Greeks were right about tying geometry to music as three music profs have connected sophisticated 3D modeling techniques to musical components to come up with a powerful new way to analyze music. "They take sequences of notes, like chords, rhythms and scales, and categorize them so they can be grouped into "families." They have found a way to assign mathematical structure to these families, so they can then be represented by points in complex geometrical spaces, much the way "x" and "y" coordinates, in the simpler system of high school algebra, correspond to points on a two-dimensional plane. "
What they found was pretty amazing in terms of how easily "western" composition could be transformed into really interesting geometric shapes (including spheres), something that Thales and his student Pythagoras, used in developing number theory to describe how reality worked. "The (Pythagoreans were) ... the first to take up mathematics ... (and) thought its principles were the principles of all things. Since, of these principles, numbers ... are the first, ... in numbers they seemed to see many resemblances to things that exist ... more than [just] air, fire and earth and water, (but things such as) justice, soul, reason, opportunity ..."
What's also fascinating about the Greeks is the fact they hated the concept of Zero. "The Babylonians invented it, the Greeks banned it, the Hindus worshiped it, and the Church used it to fend off heretics. Now it threatens the foundations of modern physics. For centuries the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. For zero, infinity's twin, is not like other numbers. It is both nothing and everything."
Addendum: Check out Zeno’s Paradox to see what happens when Zero is left out of the equation.

On the Proper Use of Language
At the same time this was going on, modular western languages like English, Russian and French took precedence in software development as complex algabraic expressions could be easily codified into the machine language of 0s & 1s used in telling what a computer should do with data, sound and images. (Modular Alphabet/Assembler = 0s & 1s. High level programming languages like Fortran, Cobol, Java and others work on top of Assembler to enable humans to build apps like Word, Photoshop and Excel.)
The reason for the foray into language was instigated by Dick Cavett's insightful Memo to Petraeus & Crocker: More Laughs, Please
To whit: (As speakers, both Petraeus and Crocker are guilty of unbearable sesquipedalianism, a word wickedly inflicted on me by my English-teaching mother. It’s one of those words that is what it says. From the Latin, literally “using foot-and-a-half-long words.” We all learned the word for words that sound like what they say — like “click” or “pop” or “boom” or “hiss” — but I’m sure the mercifully defunct Famous Writers School surely forbade using the “sesqui” word and “onomatopoeia” in the same paragraph. (You can have fun with both of them at your next cocktail party.)
But back to our story. Never in this breathing world have I seen a person clog up and erode his speaking — as distinct from his reading — with more “uhs,” “ers” and “ums” than poor Crocker. Surely he has never seen himself talking: “Uh, that is uh, a, uh, matter that we, er, um, uh are carefully, uh, considering.” (Not a parody, an actual Crocker sentence. And not even the worst.)
Here is where it gets serious: "Petraeus commits a different assault on the listener. And on the language. In addition to his own pedantic delivery, there is his turgid vocabulary. It reminds you of Copspeak, a language spoken nowhere on earth except by cops and firemen when talking to “Eyewitness News.” Its rule: never use a short word where a longer one will do. It must be meant to convey some misguided sense of “learnedness” and “scholasticism” — possibly even that dread thing, “intellectualism” — to their talk. Sorry, I mean their “articulation.”
No crook ever gets out of the car. A “perpetrator exits the vehicle.” (Does any cop say to his wife at dinner, “Honey, I stubbed my toe today as I exited our vehicle”?) No “man” or “woman” is present in Copspeak. They are replaced by that five-syllable, leaden ingot, the “individual.” The other day, there issued from a fire chief’s mouth, “It contributed to the obfuscation of what eventually eventuated.” This from a guy who looked like he talked, in real life, like Rocky Balboa. And there’s nothing wrong with that."
While reading this, I remember George Orwell's great essay Politics and the English Language whereby he discusses the literary techniques politicians (and others) use in stating policy or soliciting support for some god forsaken initiative (Iraq etc., etc.)
DYING METAPHORS. A newly-invented metaphor assists thought by evoking a visual image, while on the other hand a metaphor which is technically "dead" (e.g., IRON RESOLUTION) Examples are: RING THE CHANGES ON, TAKE UP THE CUDGELS FOR, TOE THE LINE, RIDE ROUGHSHOD OVER, STAND SHOULDER TO SHOULDER WITH, PLAY INTO THE HANDS OF, AN AXE TO GRIND, GRIST TO THE MILL, FISHING IN TROUBLED WATERS, ON THE ORDER OF THE DAY, ACHILLES' HEEL, SWAN SONG, HOTBED.
OPERATORS, or VERBAL FALSE LIMBS. These save the trouble of picking out appropriate verbs and nouns, and at the same time pad each sentence with extra syllables which give it an appearance of symmetry. Characteristic phrases are: RENDER INOPERATIVE, MILITATE AGAINST, PROVE UNACCEPTABLE, MAKE CONTACT WITH, BE SUBJECTED TO, GIVE RISE TO...
The keynote is the elimination of simple verbs. Instead of being a single word, such as BREAK, STOP, SPOIL, MEND, KILL, a verb becomes a PHRASE, made up of a noun or adjective tacked on to some general-purposes verb as PROVE, SERVE, FORM, PLAY, RENDER...The passive voice is wherever possible used in preference to the active, and noun constructions are used instead of gerunds (BY EXAMINATION OF instead of BY EXAMINING). The range of verbs is further cut down by means of the -IZE' AND 'DE-' formations, and banal statements are given an appearance of profundity by means of the NOT 'UN-' formation. Simple conjunctions and prepositions are replaced by such phrases as WITH RESPECT TO, HAVING REGARD TO, THE FACT THAT, BY DINT OF, IN VIEW OF, IN THE INTERESTS OF, ON THE HYPOTHESIS THAT; and the ends of sentences are saved from anti-climax by such resounding commonplaces as GREATLY TO BE DESIRED, CANNOT BE LEFT OUT OF ACCOUNT, A DEVELOPMENT TO BE EXPECTED IN THE NEAR FUTURE, DESERVING OF SERIOUS CONSIDERATION, BROUGHT TO A SATISFACTORY CONCLUSION, and so on and so forth.
PRETENTIOUS DICTION. Words like PHENOMENON, ELEMENT, INDIVIDUAL (as noun), OBJECTIVE, CATEGORICAL, EFFECTIVE, VIRTUAL, BASIS, PRIMARY, PROMOTE, CONSTITUTE, EXHIBIT, EXPLOIT, UTILIZE, ELIMINATE, LIQUIDATE, are used to dress up simple statements and give an air of scientific impartiality to biased judgment.
Sounds familiar doesn't it especially when anyone in power uses language like this. When combined with the fact this biased information is constantly pumped out 24/7 by the multinationals that own the media, one stops to consider if Orwell's vision of 1984 is possible. Click on the chart to see just how concentrated the media really is. Note: The chart is somewhat out of date.)
Who knows, 1984 may already be here.

Kind of Blue Plus Significant Others
This kind of subtle craftsmanship shows up in unexpected places as well as seen in the Paul Newman flick, Nobody's Fool, a story about "a rascally ne'er-do-well approaching retirement age."
Sully: I can't believe it's gonna take you that long to get me out of jail.
Wirf: Don't blame me, I'm a Jew. They're not my holidays.
Sully: A Jew? Really? I didn't know that. How come you ain't smart?
Wirf: How can I start getting you out of jail when you won't go in?
An all too tiny sampler of others too good to miss.

The Fine Structure Constant
The FSC "is the measure of the strength of the electromagnetic force that governs how electrically charged elementary particles (e.g., electron, muon) and light (photons) interact.
"...researchers have found the carbon monolayer is not crystal-clear but notably opaque, absorbing a rather large 2.3 percent of visible light. The experiments supported by theory show this number divided by Pi gives you the exact value of the fine structures constant.
The fundamental reason for this is that electrons in graphene behave as if they have completely lost their mass, as shown in the previous work of the Manchester group and repeated by many researchers worldwide."
Note: The photon is the carrier of electromagnetic radiation of all wavelengths, including gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves.
Now that scientists can actually see how light (photons) interacts with the fast and seemingly massless electrons in Graphene, the ability to design truly efficient solar collectors may be at hand, thus ushering in an age of clean energy that can change how man does business on planet earth.

This is how the experiment works
"They first shot a relatively slow-moving laser pulse through the fibre, and then sent a faster "probe wave" chasing after it. The first pulse distorts the optical properties of the fibre simply by travelling through it. This distortion forces the speedy probe wave to slow down dramatically when it catches up with the slower pulse and tries to move through it. In fact, the probe wave becomes trapped and can never overtake the pulse's leading edge, which effectively becomes a black hole event horizon, beyond which light cannot escape."

The Devil Made me do it
"Why? To honor our current leader of the free world with an "appropriate and enduring legacy, for no other president in modern American history has accomplished so much in such a short time."
Time Keeps on Ticking, Ticking into the Future
As an aside, Time keeps on Ticking... comes from a classic from Steve Miller called Fly Like An Eagle.
I Could Tell You but Then You Would Have to Be Destroyed by Me: Emblems from the Pentagon's Black World
When you consider just how big the budget is for Black Ops, the reason for all this joie de vive is rather obvious.
The classified budget of the Defense Department, concealed from the public in all but outline, has nearly doubled in the Bush years, to $32 billion. That is more than the combined budgets of the Food and Drug Administration, the National Science Foundation and the National Aeronautics and Space Administration.
Those billions have expanded a secret world of advanced science and technology in which military units and federal contractors push back the frontiers of warfare. In the past, such handiwork has produced some of the most advanced jets, weapons and spy satellites, as well as notorious boondoggles.
What makes this NY Times article so interesting is the book's source of inspiration...
What sparked his interest, Mr. Paglen recalled, were Vice President Dick Cheney’s remarks as the Pentagon and World Trade Center smoldered. On “Meet the Press,” he said the nation would engage its “dark side” to find the attackers and justice. “We’ve got to spend time in the shadows,” Mr. Cheney said. “It’s going to be vital for us to use any means at our disposal, basically, to achieve our objective.”
God, I feel safer already! Don't you?
