Gene therapy restores vision in mice.
Scientists announce gene therapy breakthrough toward making the blind see that does not involve the use of modified viruses. They used a non-viral, synthetic nanoparticle carrier to improve and save the sight of mice with retinitis pigmentosa, an inherited disease characterized by progressive vision loss and eventual blindness. 'We hope the results of our study will be instrumental in generating a cure for the debilitating blindness associated with retinitis pigmentosa and other inherited and acquired retinal diseases,' said Muna I. Naash, Ph.D., a researcher involved in the work from the Department of Cell Biology at the University of Oklahoma Health Sciences Center in Oklahoma City. 'Compacted DNA nanoparticles are an exciting treatment strategy for these diseases and we look forward to exciting new developments.'

Will the FDA kill someone you love by killing adult stem cell therapy development.
Within the next five years, it's quite possible that physicians will come into routine possession of a remarkable set of tools - a brand new way of dealing with the frailty and disabilities of aging. The tool kit is autologous stem cells derived from the patients themselves, amplified in culture, and infused back into the patient according to a precise protocol. It would be such a leap from today's medical diagnostics and treatments; it could only be called revolutionary. (It is a crime against humanity the way the FDA constantly prevents American doctors from using the most effective new cures. It kills thousands of people every month. For some diseases now American doctors use technologies that seem barely above those used by witch doctors, when compared to the miracle cures available in countries with more enlightened medical regulation. Your dog can get the miracle cure here, but thanks to the FDA desire to protect their regulatory powers, your child is doomed to death. Gay people didn't take it when FDA regulators perpetrated a holocaust on them. They followed the murderous regulators around, picketed their homes and finally forced the FDA gestapo to back off and stop killing them with their excessive delays of new AIDs drugs. Things won't change until all sick Americans rise up and demand change like the gays did. -- Editor)

Wide-view neurostimulator 'bionic eye' will soon be implanted into first recipient in Australia.
A prototype bionic eye, developed by BVA researchers at the University of New South Wales and unveiled today at the BVA consortium’s official launch at the University of Melbourne, will deliver improved quality of life for patients suffering from degenerative vision loss caused by retinitis pigmentosa and age-related macular degeneration. The device, which is currently undergoing testing, consists of a miniature camera mounted on glasses that captures visual input, transforming it into electrical signals that directly stimulate surviving neurons in the retina. The implant will enable recipients to perceive points of light in the visual field that the brain can then reconstruct into an image.

Mutation in the APC gene that causes the colon polyps that lead to cancer corrected by simple new technique.
A team at the MD Anderson Cancer Center have found that a combination of Vitamin A acetate (RAc) and TRAIL, short for tumor necrosis factor-related apoptosis-inducing ligand, kills the precancerous polyps and inhibits tumor growth in mice that have deficiencies in a tumor-suppressor gene. That gene, adenomatous polyposis coli (APC) and its downstream signaling molecules, are mutated or deficient in 80 percent of all human colon cancers, said senior author Xiangwei Wu, Ph.D.

New research shows a small square of chocolate a day lowers your blood pressure & reduces your risk of heart disease.
Researchers in Germany followed 19,357 people, aged between 35 and 65, for at least ten years and found that those who ate the most amount of chocolate – an average of 7.5 grams a day – had lower blood pressure and a 39% lower risk of having a heart attack or stroke compared to those who ate the least amount of chocolate – an average of 1.7 grams a day. The difference between the two groups amounts to six grams of chocolate: the equivalent of less than one small square of a 100g bar. (Mad cow in beef, swine flu in pork, salmonella in chicken, e coli in fruits, vegetables and juices; thank goodness there is still chocolate. - Editor)

Researcher seeking a grand unified theory of Artificial Intelligence.
In the 1950s and ’60s, artificial-intelligence researchers saw themselves as trying to uncover the rules of thought. But those rules turned out to be way more complicated than anyone had imagined. Since then, artificial-intelligence (AI) research has come to rely, instead, on probabilities - statistical patterns that computers can learn from large sets of training data. This probabilistic approach has been responsible for most of the recent progress in artificial intelligence, such as voice recognition systems, or the system that recommends movies to Netflix subscribers. But Noah Goodman, an MIT research scientist whose department is Brain and Cognitive Sciences but whose lab is Computer Science and Artificial Intelligence, thinks that AI gave up too much when it gave up rules. By combining the old rule-based systems with insights from the new probabilistic systems, Goodman thinks he has found a better way to model thought that could have broad implications for both AI and cognitive science.

The effect on markets of the world's governments going into 'national security panic mode.'
All the financial pundits are wildly underestimating the profound impact on markets the world governments going into full "national security panic mode" is having.

Once in 'national security panic mode,' our politicos will change accounting laws to allow big banks to hide enormous levels of bad debts from their depositors and investors. Give big banks, insurance companies, car makers, etc. huge bailout injections of capital. Take on ANY amount of bad assets and assume ANY amount of market risk, which they see as necessary to propping up the financial system. They will inject however much liquidity it takes to keep the stock market buoyant. Indeed, they would probably even be willing to secretly acquire trillions in common stocks. If they reckoned that was the only way to stave off a large decline in the stock market at this dangerous 'national security' threatening moment in history.

When the rules of the game you are playing have been profoundly shifted from the economic realm into the political realm. Trying to use the old rules to assess markets is profoundly foolish, but that is exactly what financial pundits are doing.

While we need to beware of this, it should not surprise us. Since this tendency is a well documented programming flaw in the human mind. All humans tend to have serious blind spots towards perception of large game-changing shifts. Typically only perceiving them well after having been trampled into the ground by them.

As Douglas Adams once observed. When your tribe's woolly mammoth hunts are giving you lots of food, material for sewing incredibly warm and comfortable clothing and for building great water proof shelters. And even providing ivory and bones that can be easily shaped into great tools for killing even more woolly mammoths. Human minds have a powerful tendency to just go with the flow and never contemplate what will happen to the bloated population of their tribe when the mammoth-fueled good-times runs out next hunting season with the death of the last woolly mammoth.

The few who can purge the old game's rules from their heads and get tuned into the new game's rules a little ahead of the pack are going to be the ones that survive and prosper in the post fiat money world.

The Keynesian theory that fiat monies, credit expansion, suppression of interest rates and other types of government interventions and controls can build a lasting prosperity is a fatally flawed theory. And humanity has just begun to pay the terrible price that will be exacted from us for allowing the world's nation states to remodel our economies using these flawed theories.

So as you read those pundits who are trying to interpret the new game using the old game's rules, beware of letting this retard further your mind's already limited capacity to perceive and adjust to a systemic shift.

Enhancing the activity of certain immune cells may offer cure for arthritis & other autoimmune diseases.
By enhancing the activity of immune cells that protect against runaway inflammation, researchers may have found a novel therapy for rheumatoid arthritis and other autoimmune diseases. In a new study the researchers reveal how treating these immune cells with an investigational drug wards off inflammation by holding a particular enzyme at bay. 'This is an unusual mechanism that could provide a potential therapeutic approach for the treatment of autoimmune diseases like rheumatoid arthritis or inflammatory diseases like Crohn's disease,' says Michael Dustin, PhD, the Irene Diamond Professor of Immunology and professor of pathology at NYU Langone Medical Center.

Micro generators make energy from random ambient vibrations for wearware & implants.
Tiny generators developed at the University of Michigan could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker or wireless sensor. The energy-harvesting devices, created at U-M's Engineering Research Center for Wireless Integrated Microsystems, are highly efficient at providing renewable electrical power from arbitrary, non-periodic vibrations. This type of vibration is a byproduct of traffic driving on bridges, machinery operating in factories and humans moving their limbs, for example.

Protein linked to problems with executive thinking skills.
New research shows that a high level of C-reactive protein (CRP), a marker for inflammation in the blood, is associated with brain changes that are linked to problems with executive thinking skills. Scientists examined 447 stroke and dementia-free people with an average age of 63. Participants underwent MRI brain scans such as diffusion tensor imaging (DTI), a technique that measures water molecule movements in the brain. They also completed tests that measured verbal memory, word fluency and executive function, the process in the brain that allows for planning, decision making and selection of appropriate behavior.

Genetic mod energy breakthrough alters microbes to ooze oil for renewable biofuel.
Researcher Xinyao Liu and professor Roy Curtiss at Arizona State University's Biodesign Institute have modded photosynthetic microbes to secrete oil. the new technology bypassing energy and cost barriers that have hampered green biofuel production. 'The real costs involved in any biofuel production are harvesting the fuel precursors and turning them into fuel,' said Roy Curtiss, director of the Biodesign Institute's Center for Infectious Diseases and Vaccinology. 'By releasing their precious cargo outside the cell, we have optimized bacterial metabolic engineering to develop a truly green route to biofuel production.' Photosynthetic microbes called cyanobacteria offer attractive advantages over the use of plants like corn or switchgrass, producing many times the energy yield with energy input from the sun and without the necessity of taking arable cropland out of production.

Scientists reverse Alzheimer's-like memory loss in fruit flies.
By blocking the cellular signaling activity of a protein, a team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has prevented memory loss in fruit flies caused by brain plaques similar to those thought to cause Alzheimer's disease in humans. The study also resolves a long-standing controversy about the role of this protein, PI3 kinase, which was previously thought to have a protective function against the disease. 'Our work suggests that the peptides, or fragments, of beta-amyloid associated with Alzheimer's disease directly increase the activity of PI3 kinase, which in turn causes memory loss and increases the accumulation of plaque in the brain,' explains CSHL Professor Yi Zhong, who led the research team.

Researchers developing new anti-cancer gene therapy approach that uses lentiviral vectors.
Helmholtz Zentrum Munchen has launched a new cooperative project with SIRION BIOTECH GmbH in Martinsried to develop new therapeutic approaches against lymphoid tumors. The two partners will seek to further develop lentiviral vector systems to better understand the disease mechanisms of this cancer form and to devise approaches for treatment. The future of gene therapy approaches in cancer treatment is especially dependent on the quality of the vectors involved in the regulation of gene expression in the tumor cells. Lentiviruses are a very promising vector system for this - they even reach difficult-to-access cell types such as the hematopoietic cells of the blood-forming system.

The market in used human body parts -- everybody gets rich but the donor.
The process whereby used human body parts are transferred from the original owner to the final owner consists of two exchanges. And, while the law prohibits a free market in one of these, the law allows a restricted market in the other. There are three parties involved: the original owner of the part (hereinafter, specifically not referred to as the 'donor'), the medical industry, and the final owner (the recipient, hereinafter, specifically not referred to as the 'donee'). (I've certainly never understood why the surgeon can make $50,000 for three hours work, and the hospital can make $50,000 for a few hours use of an operating room, a a few days in a hospital bed, and both those are just fine. But somehow it is a great evil if the donor makes a dime for donating an organ. I guess surgeons and hospitals can buy politicos by the score, while individual donors could only actually use the money. -- Editor.)

Uncharted terrortory, a new poll shows 79% of Americans fear our zombie economy might collapse.
Not during the darkest hours of 9/11, Vietnam, the Cuban missile crisis, Korea or even World War II have Americans been this skittish about our economy. A new poll finds that 79 percent of voters think it’s possible the economy could collapse, including large majorities of Democrats (72 percent), Republicans (84 percent) and independents (80 percent). You'd have to go all the way back to the depression era just prior to World War II, October 30, 1938, to find a time when the American herd was this skittish about anything. That was the day that the broadcast of Orson Wells' radio drama "War of the Worlds" sent Americans fleeing their homes in panic all across the land. It wasn't an economic collapse they feared back then. It was the gathering clouds of a new world war.
Never before has there been this much skittishness about an economic collapse of our nation, but why are Americans so freaked? Aren't our politicos, central bankers, pundits and talking heads all constantly reassuring us that all is sound?
I think it is Hollywood that is to blame. For giving so many Americans such a keen understanding of exactly what a zombie is. Thanks to Hollywood, Americans now know that temporarily reanimating a corpse doesn't really make it a living thing again. So, just because all the world's politicos and central bankers went into full panic 'national security' mode and began printing trillions of paper dollars to spend on overt and covert operations to paint a little rouge on the pale dead corpses of the world's financial markets. Doesn't mean that those markets are actually alive again. Not at all, they could just be lumbering along muttering: "Feed me, not brains, your children's futures."
Bloomberg has been suing under the Freedom of Information Act to find out the true magnitude and nature of their 'national security' financial shenanigans, but our politicos and central bankers are hell bent on keep as much of what they have done a deep dark secret as they possibly can.
Americans aren't buying their zombie markets. They are frightened by them. And this is why even more of Americas are feeling skittish today than was the case back in 1938, when so many of them ran out into the streets in panic over a radio drama about a Martian invasion.
Shhhh! Careful, the slightest little sound could trigger a stampede. Whatever you do, don't anyone step on a twig.

Memory decline linked to an inability to ignore distractions.
One of the most common complaints among healthy older adults relates to a decline in memory performance. This decline has been linked to an inability to ignore irrelevant information when forming memories. In order to ignore distracting information, the brain should act to suppress its responses to distractions, but researchers have shown that in older adults there is in fact an increase in brain activity at those times. In a new study researchers at the University of California San Francisco have shown that even prior knowledge of an impending distraction does not help to improve the working memory performance of older adults.

A change of mind: "Plasticity — the brain's ability to change in response to external input — is critical for most cognitive functions, including learning and memory. Those changes usually involve a strengthening or weakening of synapses, the connections between brain cells (neurons). MIT neuroscientists have now found that a single protein, known as Arc, appears to control neurons’ ability to strengthen and weaken their synapses by regulating the number of neurotransmitter receptors on their surfaces. The finding could help researchers identify new drug targets for Fragile X and Angelman syndromes — inherited forms of mental retardation that have been linked to deficits of Arc.

Same genes may exert opposite effects in diabetes and inflammatory bowel disease.
Both type 1 diabetes (T1D) and inflammatory bowel disease (IBD) are autoimmune disorders—conditions in which the body's immune system overreacts, resulting in disease. Many such autoimmune diseases share genes in common, acting on shared biological pathways. 'This finding shows the genetic architecture of these diseases is more complex than previously thought,' said study leader Hakon Hakonarson, M.D., Ph.D., director of the Center for Applied Genomics at The Children's Hospital of Philadelphia.

Why science can answer your moral questions much better than any religion.
Questions of good and evil, right and wrong are commonly thought unanswerable by science. But Sam Harris argues that science can -- and should -- be an authority on moral issues, shaping human values and setting out what constitutes a good life. Sam Harris' best-selling books argue that religion is ruinous and, worse, stupid -- and that questioning religious faith is necessary to save our civilization. (Even if the cosmos has a creator, thousands of men have written screeds claimed to be the true word of that creator. No two agree, which one to believe? There is no way to know. If a creator does exist, there is only one way you can be certain you are looking directly into that creator's mind. And that is by making a rigorous study of the creator's creation, the cosmos all around you. This is what science is all about. Creator or no creator, either way, science is the best path ahead for individual humans and our species as a whole. -- Editor)

How to incorporate biofunctionality into nano-devices for medical, health devices.
A team led by researchers from North Carolina State University has published a paper that describes the use of a technique called atomic layer deposition to incorporate "biological functionality" into complex nanomaterials, which could lead to a new generation of medical and environmental health applications. For example, the researchers show how the technology can be used to develop effective, low-cost water purification devices that could be used in developing countries. 'Atomic layer deposition is a technique that can be used to create thin films for coating metals or ceramics, and is especially useful for coating complex nanoscale structures,' says Dr. Roger Narayan, the paper's lead author. 'This paper shows how atomic layer deposition can be used to create biologically functional materials, such as materials that have antibacterial properties. Another example would be a material that does not bond to proteins in the body, which could be used for implantable medical sensors.'

New growth factor found that greatly stimulates stem cell regeneration both in culture and within the body.
Scientists at Duke University Medical Center have identified a new growth factor that stimulates the expansion and regeneration of hematopoietic (blood-forming) stem cells in culture and in laboratory animals. The discovery overcomes one of the most frustrating barriers to cellular therapy, that stem cells are so few in number and so stubbornly resistant to expansion, and could lead to broader application of cord blood transplants for the large numbers of patients who do not have an immune-matched donor. "Perhaps more importantly, systemic treatment with pleiotrophin may have the potential to accelerate recovery of the blood and immune system in patients undergoing chemotherapy or radiotherapy," said John Chute, M.D., a stem cell transplant physician and cell biologist at Duke and senior author of the paper.

It's not your genes that make you unique, so much as it is the DNA sequences that surround your genes.
The key to human individuality may lie not in our genes, but in the sequences that surround and control them, according to new research by scientists at the Stanford University School of Medicine and Yale University. The interaction of those sequences with a class of key proteins, called transcription factors, can vary significantly between two people and are likely to affect our appearance, our development and even our predisposition to certain diseases, the study found. The discovery suggests that researchers focusing exclusively on genes to learn what makes people different from one another have been looking in the wrong place. 'We are rapidly entering a time when nearly anyone can have his or her genome sequenced,' said Michael Snyder, PhD, professor and chair of genetics at Stanford. 'However, the bulk of the differences among individuals are not found in the genes themselves, but in regions we know relatively little about. Now we see that these differences profoundly impact protein binding and gene expression.'

The US health care system is stuck in the 'mainframe' era, circa 1959, tethered to big, unwieldy centralized systems: hospitals, doctors, nursing homes. As our aging population booms, it's imperative that we create personal, networked, home-based health care for all. Indeed, it is the only way to prevent the rising cost of healthcare from bankrupting our society. (The biggest inhibiting factor to the 'personalization' of the medical industry is the FDA's murderous regulatory system. Think about how innovation happens in computers. Someone designs something new and cool that only the rich can afford. Then lots of other companies pile in with constantly cheaper versions, until very soon the same device can be obtained for $20 at Walmart. However, by requiring many years of costly regulatory approvals for each new iteration of a medical technology the FDA completely stifles rapid innovation in medicine. Millions now die prematurely annually around the world as a direct result of the FDA's deadly and destructive system of regulation. - Editor)

Two proteins that regulate intestinal inflammation could be used to prevent colon cancer?
McGill University Health Centre researchers have demonstrated that the Caspase-1 protein plays a crucial role in inflammation regulation and intestinal tissue repair. But too much of any good thing can sometimes be bad. They also demonstrated that if Caspase-12--the protein that blocks Caspase-1--is absent, the inflammation mechanism caused by Caspase-1 goes out of control. Their findings, which were published in the journal Immunity, open the door to a greater understanding of and more targeted treatment strategy for preventing diseases linked to inflammation of the intestine as well as certain cancers.

European police investigating 30 offers to sell organs for transplant on Spanish web sites.
'Man aged 29, in perfect health, is selling one of his kidneys for EUR 150 000.' This message, published on the free website habitamos.com and condemned by the Spanish consumer association Facua, was reported by various European media. Those charged with looking into this case by the Spanish Health Ministry and police conducting the investigation identified around 30 similar proposals on 13 websites. Wait now let me get this. A surgeon can charge $50,000 for 4 hours work doing a transplant. The hospital can charge $50,000 for 4 hours in an operating room and 4 days rent on a room you share with a roommate, spaces that kill over 60,000 a year because they aren't kept clean enough. However, if someone wants $50,000 for their risk and pain for donating a kidney to someone in need of it. Then they are evil, vile, greedy, criminal and must be jailed???? The old order's worldview is just insane.

DNA nanotechnology breakthrough offers promising applications in medicine.
A team of McGill Chemistry Department researchers led by Dr. Hanadi Sleiman has achieved a major breakthrough in the development of nanotubes – tiny 'magic bullets' that could one day deliver drugs to specific diseased cells. Sleiman explains that the research involves taking DNA out of its biological context. So rather than being used as the genetic code for life, it becomes a kind of building block for tiny nanometre-scale objects. Using this method, the team created the first examples of DNA nanotubes that encapsulate and load cargo, and then release it rapidly and completely when a specific external DNA strand is added. One of these DNA structures is only a few nanometres wide but can be extremely long, about 20,000 nanometres. (A nanometre is one-10,000th the diameter of a human hair.) Until now, DNA nanotubes could only be constructed by rolling a two-dimensional sheet of DNA into a cylinder. Sleiman's method allows nanotubes of any shape to be formed and they can either be closed to hold materials or porous to release them. Materials such as drugs could then be released when a particular molecule is present.

Disabling Skp2 gene helps shut down cancer growth.
Researchers from The University of Texas M. D. Anderson Cancer Center and Memorial Sloan-Kettering Cancer Center have discovered that the Skp2 gene is involved in promoting cell cycle regulation, cell proliferation, cell growth and the formation of tumors. And it is overexpressed in a variety of human cancers, according to lead author Hui-Kuan Lin, Ph.D. Lin and colleagues found that inactivating Skp2 after oncogenes are overexpressed stifles cancer growth by causing senescence - the irreversible loss of a cell's ability to divide and grow. Harnessing the power of cellular senescence to push rapidly dividing cells into a dormant state might provide another way to prevent or control common malignancies.

Research team identifies genes linked to ulcerative colitis.
A study of the human genome led by Cedars-Sinai Medical Center researchers has now identified genes linked to ulcerative colitis, offering clues as to what causes the condition and potential avenues for new therapies to treat the disease. The study examined genes of nearly 13,000 patients to determine which parts of the genome are linked to ulcerative colitis. The study demonstrated more than 30 regions of the genome are connected to the risk of developing ulcerative colitis. 'This gives us a number of insights into the disease,' said Dermot P.B. McGovern, M.D., Ph.D., director of Translational Medicine for the Inflammatory Bowel and Immunobiology Research Institute at Cedars-Sinai Medical Center and primary author of the paper. 'An increased understanding of the genetics gives us some insight into what causes ulcerative colitis and will potentially help us indentify new therapies for ulcerative colitis.'

Researchers identify key mechanism that guides cells to form heart tissue
Researchers at the Keck School of Medicine of the University of Southern California (USC) have identified a key cellular mechanism that guides embryonic heart tissue formation—a process which, if disrupted, can lead to a number of common congenital heart defects. Heart tissue forms in two distinct phases known as the First Heart Field, which includes the left ventricle and portions of both atrial chambers, and the Second Heart Field (SHF), which consists of the right ventricle and outflow tract. In humans, the process occurs within the fourth week of development. Using animal models, Keck School of Medicine researchers found that retinoic acid (RA), a derivative of vitamin A, regulates the SHF tissue formation and the septation, or division, of the outflow tract into the ascending aorta and the pulmonary artery.

Augmented reality contact lens puts a reality augmenting net connection onto the surface of your eye.
Professor Babak Amir Parviz and his students from the University of Washington have developed an augmented contact lens that embeds AR technology straight into your eye. An antenna at the periphery collects incoming RF energy from a separate portable transmitter. Power-conversion circuitry provides DC power to other parts of the system and sends instructions to the display control circuit. The display, at the center, might consist of LEDs, which would turn on and off, or LCD-like elements, whose transparency would be modulated by the control circuit. An energy-storage module, perhaps a large capacitor, is connected to a solar cell, which could provide a boost to the lens. A biosensor samples the surface of the cornea, performs an analysis, and provides data to the telecommunication module to transmit to an external computer.

Fixing a cellular defect could block many forms of cancer.
mTOR, which stands for the 'mammalian target of rapamycin.' controls several important processes in mammalian cells, including cell survival and proliferation. One of the most significant of these processes is the production of proteins within a cell, the control of which is known as translational control. mTOR integrates information about the cell's nutritional and energy needs, and prompts the cell to manufacture key proteins for cell growth. Cancer cells exploit this signal for their own growth. Now researchers at the University of California, San Francisco School of Medicine have found that when the cells in the body lose the ability to control mTOR activity, mTOR is considered 'hyperactivated.' This hyperactivation causes protein synthesis rates to climb. Cells begin to proliferate without limits and simultaneously become immortal, which leads to tumor formation. According to the study team, this discovery has broad clinical implications in the fight against cancer and could affect treatment of lymphoma and many other forms of the disease, including prostate cancer, breast cancer, colorectal cancer, brain cancer and multiple myeloma.

Forget fingerprints, now you can be identified by the unique genomic profile of bacteria living on your skin.
The researchers extracted bacterial DNA from numerous samples taken from the three keyboards and sequenced more than 1,400 copies of bacterial ribosomal gene from each sample to identify the individual species of bacteria each sample contained, finding they could match the three individuals with the keyboards they used. They then took swabs from computer mouses of nine different people. When they compared the bacteria found in the samples to a database of microbial communities found on 270 hands of people who had never touched any of the computer mouses, the researchers found that the bacteria on each person's mouse was more similar to that on their hand than to samples in the database. So far, Fierer notes, the technique is extremely preliminary, but it could one day be as accurate as techniques like DNA or fingerprint analysis, he says.

Memristors fill in 'missing link' that has kept scientists from engineering artificial neurons & brain-like computers.
Researchers say that the memristor, an new electronic device first engineered in 2008, has the ability to behave uncannily like the junctions between the neurons in your brain. A memristor is a device that, like a resistor, opposes the passage of current. But memristors also have a memory. The resistance of a memristor at any moment depends on the last voltage it experienced, so its behaviour can be used to recall past voltages. Now memristors are being used in a US military-funded project trying to make brain-like computers, says Wei Lu, who led the team at the University of Michigan in Ann Arbor that demonstrated this new neural-computing behavior of memristors.

In a breakthrough towards the humods future, where each of us carries millions of nano-implants to monitor and maintain our health and to allow our brains to connect directly to the internet. Researchers at Korea University in Seoul have transmitted broadband data at a rate of 10 megabits per second through a person's arm using two electrodes placed on their skin 30 centimetres apart. The thin, flexible electrodes use significantly less energy than a wireless link like Bluetooth. That's because low-frequency electromagnetic waves pass through skin with little attenuation, a route that also shelters them from outside interference. The next step is to get a full-blown I3 (implant to implant to internet) mesh network up and running inside someone's body.

New Boolean bot can find genes in milliseconds that would take researchers years of tedious work to find.
Stanford University computer scientist Debashis Sahoo, PhD, seemed to be offering some kind of trick when he asked researchers at the Stanford Institute for Stem Cell Biology and Regenerative Medicine to pick any two genes already known to be involved in stem cell development. Finding such genes can take years and hundreds of thousands of dollars, but Sahoo was promising the skeptical stem cell scientists that, in a fraction of a second and for practically zero cost, he could find new genes involved in the same developmental pathway as the two genes provided. Sahoo realized that these asymmetric relationships could be found by applying Boolean logic, in which the researchers established a series of if/then rules and then searched data for candidates that satisfied all the rules. For example, scientists might know that gene A is very active at the beginning of cell development, and gene C is active much later. By screening large public databases, Sahoo can find the genes that are almost never active when A is active, and almost always active when C is active, in many other types of cells. Researchers can then test to determine whether these genes become active between the early and late stages of development.

Losing a single gene lets mice and could let humans regenerate lost limbs and other tissue.
The absence of just a single gene, called p21, confers a healing potential in mice long thought to have been lost through evolution in all mammals, the ability to regenerate lost or damaged tissue. Unlike typical mammals, which heal wounds by forming a scar, these mice begin by forming a blastema, a structure associated with rapid cell growth and de-differentiation as seen in amphibians. According to the Wistar researchers, the loss of p21 causes the cells of these mice to behave more like embryonic stem cells than adult mammalian cells, and their findings provide solid evidence to link tissue regeneration to the control of cell division. "Much like a newt that has lost a limb, these mice will replace missing or damaged tissue with healthy tissue that lacks any sign of scarring," said the project's lead scientist Ellen Heber-Katz, Ph.D., a professor in Wistar's Molecular and Cellular Oncogenesis program. "While we are just beginning to understand the repercussions of these findings, perhaps, one day we’ll be able to accelerate healing in humans by temporarily inactivating the p21 gene."

Breakthrough in understanding of how your body repairs itself big step toward keeping your body forever young.
New research led by scientists at the University of Essex has given an insight into how the body finds damage in the DNA code to repair it. From rays of sunlight to harmful tobacco smoke, our bodies are bombarded every single day by a range of environmental toxins which damage our DNA. Your body work hard to find this damage and repair it, but how the damage is found in the first place is one the great unanswered questions. Now new research led by scientists at the University of Essex has given an insight into how your body finds damage to your DNA code to allow it to be repair. As lead researcher Dr Neil Kad, from the Department of Biological Sciences, explained, understanding the processes of how the body repairs itself can lead to a greater understanding of cancer and the ageing process, a first step towards improving your body's ability to repair such damage.
The researchers tagged two bacterial repair proteins, called UvrA and UvrB, with quantum dots - semi-conductor nanocrystals that light up in different colours - to make it possible to see how they moved. They also stretched the usually clumped DNA into multiple 'tightropes' to see the process more clearly. They found that the UvrA proteins randomly jumped from one DNA molecule to the next, holding on to one spot for about seven seconds before hopping to another site. But the real breakthrough came when it was discovered that the search for damage became quicker and more efficient when UvrA formed a complex with UvrB molecules (UvrAB). This new, quicker search cut the total time to check the genome from three hours down to just 13 minutes.

Ironically, the Greens have become one of the chief forces pushing our planet towards climate catastrophe.
Due to the northern latitudes and cloudy weather, solar power just isn't an effective way to fill Europe's electricity needs. And Europe's lack of the powerful winds that sweep across America's vast great plain, means that wind energy can only do so much. The result is that for each nuclear power plant that Europe's Greens block, Europe's use of fossil fuels to produce electricity spikes upward. Overall, it jumped from 54% of power production in 1995 to 58% in 2007. Nuclear power appears to be the only technology we have available that is capable of reducing CO2 emissions fast enough to avert a global climate catastrophe. And the longer it takes Greens to accept the nuclear reality. The more likely it is that efforts to prevent all the world's coastal cities from slipping beneath rising seas, will be doomed to failure. Resilient environmentalism can save the planet, but the old dogmatic environmentalism will speed its destruction.

Rather, the replays often were paths that the rats had rarely taken or, in some cases, had never taken, as if the rats were trying to build maps to help them make better navigation decisions. 'The point of the cognitive map is flexibility. It gives animals the ability to plan novel paths within their environment,' said University of Minnesota Medical School researcher A.

Fasten your seat belts folks. Because the years just ahead are going to be one very wild ride.


Unfolding in parallel are two polar-opposite civilization make or break events. Nano and bio, have joined the worldwide digital network as the three most powerful sciences ever to come out of a laboratory. There is simply no way to exaggerate the miraculous impact these technologies will have on our civilization. Consider the effect of a reasonably priced system that mods photosynthesis to make hydrogen and oxygen instead of sugar, able to power an American-sized McMansion 24/7, plus produce all the fuel for all your vehicles. Or an implantable system that can monitor and mod your biochemistry to always keep you in perfect health. Or scores of other bio/nano inventions.

But there is also a complete economic/political train wreck unfolding. Caused by the abject failure of the fiat money/credit expansion economic theory that has driven the design of the world's economic system for most of the last century. Only hard work and savings can produce real wealth, not below zero interest rates and speculating on asset bubbles.

Currently, our civilization is like a tiny boat bobbing around dead in the water as two giant tsunamis roar towards us. One is aligned exactly at our stern and seems likely to power our progress at speeds never before dreamt of. But the other is barreling from directly off our starboard side. Making it certain to roll and rip our tiny little boat to smithereens when it fully arrives. (No the economic problems aren't over, as the politicos are assuring you, they are just getting started.)

Oh, and as if things weren't complicated enough already. Buried withing the 'good' wave are undertows that super-empower individuals to the point that one knowledgeable person might be able to take on all of civilization and win. Or bring about the extinction of our species, if he or she is crazy enough to have that as their goal.

It bears repeating. Fasten your seat belts folks. Because the years just ahead are going to be one very wild ride.

Yes, we are already going up the side of the 'bad' wave. It has arrived first.

Necessary, because when your boat is surfing atop a tsunami, any mistake not instantly corrected can precipitate an extinction level failure.

Golden nano-assassins identify, target and kill cancer cells, while leaving normal cells alone.
Researchers have synthesized nanoparticles – shaped something like a dumbbell – made of gold sandwiched between two pieces of iron oxide. They then attached antibodies, which target a molecule found only in colorectal cancer cells, to the particles. Once bound, the nanoparticles are engulfed by the cancer cells. To kill the cells, the Cornell University researchers use a near-infrared laser, which is a wavelength that doesn't harm normal tissue at the levels used, but the radiation is absorbed by the gold in the nanoparticles. This causes the cancer cells to heat up and die. 'This is a so-called 'smart' therapy,' said. 'To be a smart therapy, it should be targeted, and it should have some ability to be activated only when it's there and then kills just the cancer cells.'

Immune cells use a nano-bungee to grapple and kill dangerous intruders, new research shows.
Immune cells ensnare dangerous cells that are on the run with a bungee-like nanotube, according to researchers from Imperial College London. Natural killer (NK) cells are your first line of defence against dangerous cells, such as tumour cells and cells infected with bacteria and viruses. Researchers are keen to understand how NK cells fight infection and stop tumours from growing, so they can design molecules that mimic their ability. Prior to this new study, it was known that NK cells can kill their target cells by attaching to them, but not that they had such a sophisticated tool for snaring, a bungee-like membrane nanotube.

New approach to immune cell analysis facilitates creation of an autodoc implant that can accurately monitor and maintain your health.
Investigators have developed a new mathematical approach to analyze molecular data derived from complex mixtures of immune cells. This approach, when combined with well-established techniques, readily identifies changes in small samples of human whole blood, and has the potential to distinguish between health and disease states. Until now, scientists had to separate out the cell types from a mixture prior to analysis to verify that actual changes in gene expression had occurred. But cell separation is time-consuming and costly, and requires large samples of blood. To overcome such obstacles, the study team developed a computational approach called cell specific significance analysis of microarrays (csSAM). "What csSAM does is marry the concepts of cell separation with the ease of analyzing large families of genes on a microarray," explains Atul Butte, M.D., Ph.D., of Stanford University. "Using a mathematical approach, we can virtually separate out the different cell types found in blood, determine the gene expression patterns of these cell types, and identify which changes in gene expression are due to actual disease and which are simply due to variations in the cell proportions.

The memes that determine the survival longevity of online communities.
The more heterogeneous the community of an online chat channel, the more chances the channel has to survive over time. This has been concluded in a new joint study carried out by researchers of the University of Haifa and the New Jersey Institute of Technology. 'This study has shown that an essentially social characteristic significantly influences the survival chances of an online community,' says Dr. Daphne Raban of the University of Haifa who took part in the study. The study, headed by Dr. Quentin Jones of the New Jersey Institute of Technology aimed to examine what factors could best predict the chances of an online community to survive over time.

A breakthrough solar technology can practically provide all your electricity and vehicle fuel, rain or shine from a roof collector.
A new type of photovoltaic array, invented by Massachusetts Institute of Technology chemistry professor Dan Nocera, uses a cobalt-phosphate catalyst to convert water and carbon dioxide into hydrogen and oxygen. What Dr. Nocera has done is to mod the extremely efficient organic photosynthesis process of plants. So that instead of storing solar energy in the form of sugars, it is stored as hydrogen, which can power our homes at night and fuel our vehicles. All that is required to power a modern American house and vehicles is a roughly 1,000 sq foot collector up on your rooftop. We've been watching this amazing technology move out of the lab and towards a commercial product with great anticipation. It appears to be truly a world changing breakthrough.

Ritalin can boost your ability to learn by increasing your brain's plasticity.
Doctors treat millions of children with Ritalin every year to improve their ability to focus on tasks, but scientists now report that Ritalin also directly enhances the speed of learning. In animal research, the scientists showed for the first time that Ritalin boosts both of these cognitive abilities by increasing the activity of the neurotransmitter dopamine deep inside the brain. Neurotransmitters are the chemical messengers neurons use to communicate with each other. They release the molecule, which then docks onto receptors of other neurons. The research demonstrated that one type of dopamine receptor aids the ability to focus, and another type improves the learning itself. The scientists also established that Ritalin produces these effects by enhancing brain plasticity – strengthening communication between neurons where they meet at the synapse. Research in this field has accelerated as scientists have recognized that our brains can continue to form new connections – remain plastic – throughout life.

Researchers find that without sufficient Vitamin D in your blood stream, you don't have an immune system.
Scientists at the University of Copenhagen have discovered that Vitamin D is crucial to activating your immune defenses and that without sufficient intake of the vitamin, the killer cells of your immune system – T cells - will not be able to react to and fight off serious infections in your body. For your T cells to detect and kill foreign pathogens such as clumps of bacteria or viruses, the cells must first be 'triggered' into action and 'transform' from inactive and harmless immune cells into killer cells that are primed to seek out and destroy all traces of a foreign pathogen. The researchers found that T cells rely on vitamin D in order to activate and they would remain dormant, 'naive' to the possibility of threat if vitamin D is lacking in your blood.

Substantive conversations raise your sense of well being substantially but the same isn't true of small talk.
Psychological scientists at the University of Arizona and Washington University in St. Louis investigated whether happy and unhappy people differ in the types of conversations they tend to engage in. Volunteers wore an unobtrusive recording device called the Electronically Activated Recorder (EAR) over four days and more than 20,000 recordings were analyzed along with personality and well-being assessments. The happiest participants had twice as many substantive conversations and one third as much small talk as the unhappiest participants. The findings suggest that the happy life is social and conversationally deep rather than solitary and superficial. Researchers note, "Just as self-disclosure can instill a sense of intimacy in a relationship, deep conversations may instill a sense of meaning in the interaction partners."

Can deleting the gene for one enzyme create healthier humans? It seems to have done so for mice.
"It was a surprising and unexpected finding," said Richard Lehner of the University of Alberta. "With this gene deleted, not only was there a decline in very low-density lipoproteins in the whole mouse, it also affected metabolism in fat tissue. Insulin-secreting cells became smaller, suggesting that they didn't have to work as hard to secrete insulin, and the mice became more insulin sensitive." The animals ate more, but they also expended more energy and showed no change in body weight. Very low-density lipoproteins (VLDLs) are a form of 'bad' cholesterol, Lehner explained. TGH normally frees up triglycerides from their storage place in the liver, releasing them for assembly into VLDLs. Therefore, one might expect that loss of TGH would have ill effects on the liver, as triglycerides would build up there. Indeed, he says, similar experiments with other enzymes have shown such an effect. "We didn't observe that here," Lehner said. Instead of being stored in liver, triglycerides were burned and the liver also compensated by synthesizing less fat.
