Brain mechanism discovery could switch-off alcohol dependency
Researchers at the Sahlgrenska Academy, University of Gothenburg, Sweden, have discovered a new brain mechanism involved in alcohol addiction involving the stomach hormone ghrelin. When ghrelin's actions in the brain are blocked, alcohol's effects on the reward system are reduced. It is an important discovery that could lead to new therapies for addictions such as alcohol dependence.

Scientists claim to have found a potential 'biological fountain of youth'
Scientists say their new discovery could lead to the single most important medical breakthrough in human history -- significantly longer lifespans. "Ultimately we are trying to discover what underlying mechanisms allow for some animal species to live a very long time with the hope that we might be able to develop therapies that allow people to age more slowly," said Asish Chaudhuri, Professor of Biochemistry, VA Medical Center, San Antonio, Texas and the senior researcher involved in the work.

Asish and colleagues made their discovery by extracting proteins from the livers of two long-lived bat species (Tadarida brasiliensis and Myotis velifer) and young adult mice and exposed them to chemicals known to cause protein misfolding. After examining the proteins, the scientists found that the bat proteins exhibited less damage than those of the mice, indicating that the bats have a mechanism for maintaining proper protein structure under extreme stress that other organisms lack. Once this mechanism is fully understood, the researchers believe that it could lead to therapies capable of significantly extending human lifespans.

Brain section multitasks to handle both phonetics and decision-making

A front portion of the brain that handles tasks like decision-making also helps decipher different phonetic sounds, according to new Brown University research. This section of the brain - the left inferior frontal sulcus - treats different pronunciations of the same speech sound the same way. This solves the mystery of how the brain is able to equate sounds that can sound radically different when spoken by different people.

First implant of what could prove to be a much better cyborg heart

Abiomed recently announced the successful implant of its AbioCor Total Replacement Heart, performed at Robert Wood Johnson University Hospital by Mark Anderson, M.D., associate professor of surgery at UMDNJ-Robert Wood Johnson Medical School. This is the first AbioCor implant since the completion of clinical trials and Humanitarian Device Exemption (HDE) approval from the U.S. Food and Drug Administration (FDA). The heart was implanted in a 76-year-old male patient diagnosed with congestive, end-stage heart failure, who did not qualify for a heart transplant or other available therapies, making him eligible for the AbioCor implant.

Suggestions for surviving in troubled times
There is growing evidence for the theory that the last half of the 20th century was a period of extraordinary stability. But now we have returned to the more typical human condition, as previously experienced in the first half of the 20th century. A period that saw two World Wars, a flu outbreak that killed 50 to 100 million, a Great Depression and numerous 'great leaders' that slaughtered tens of millions of their own citizens to consolidate their power.

Let's hope things won't get that bad, but a good Civilization 2.0 thinker, John Robb over at Global Guerrillas, has some interesting suggestions for surviving in troubled times.

A 'perfection tool' that will let Big Brother track you everywhere
It's a frequent scene in television crime dramas: clever police technicians zoom in on a security camera video to read a license plate or capture the face of a hold-up artist. But in real life, enhancing low-quality video has not been an easy task -- until now. Researchers at Tel Aviv University have developed a new video perfection tool that can see what the naked eye cannot in either live or recorded video, in either color or black-and-white. "This enhancement of resolution can be a critical factor in locating terrorists or identifying criminal suspects," says Prof. Yaroslavsky.

The millions of security video cameras being installed are on the verge of being able to track you everywhere you go. Do you really want to live in a Big Brother state?

Daily sex helps to reduce sperm DNA damage and improve fertility
Daily sex improves men's sperm quality by reducing the amount of DNA damage. "I thought that frequent ejaculation might be a physiological mechanism to improve sperm DNA damage, while maintaining semen levels within the normal, fertile range," explained Dr David Greening, specialist in reproductive endocrinology and infertility at Sydney IVF. To investigate this hypothesis, Dr Greening studied 118 men who had higher than normal sperm DNA damage as indicated by a DNA Fragmentation Index (DFI). The men were instructed to ejaculate daily for seven days. When the men's sperm was re-assessed on the seventh day DFI had dropped from 34% to 26%.

One step test finds genetic and chromosomal abnormalities in embryos
A one-step embryo test for both genetic and chromosomal abnormalities has been developed by researchers based in the USA and the UK. The technique, known as genome-wide karyomapping, was capable of not only detecting diseases caused by a specific gene mutation, in this case cystic fibrosis, but that it was also capable of detecting aneuploidy (an abnormal number of any of the 23 pairs of chromosome) at the same time. Clinical trials for couples seeking fertility treatment will begin later this year.

Process by which your brain repairs itself discovered
Neural stem cells are your brain's repair system. These cells are capable of self-renewal to form new stem cells or differentiate into neurons, astrocytes or oligodendrocytes. Astrocytes have supportive functions in the environment of neurons, while oligodendrocytes form the myelin layer around axons in order to accelerate neuronal signal transmission. But how does a neural stem cell know which type of brain cell it is supposed to develop into?

"It has been well defined that Notch signaling drives the formation of astrocytes from neural stem cells while it suppresses the formation of neurons and the maturation of oligodendrocytes" explains Mirko Schmidt at the Institute of Neurology at the Goethe University Frankfurt. Inhibition of Notch signaling reverses the situation and more neural stem cells differentiate into neurons. This is exactly what happened upon the addition of the secreted protein EGFL7 (Epidermal Growth Factor-like domain 7).

Aerobic activity keeps your brain young
A long term study from the University of North Carolina at Chapel Hill School of Medicine finds that aerobic activity will keep your brain young. The brain's blood vessels naturally narrow and become more tortuous with advancing age, but the study showed the cerebrovascular patterns of active patients appeared "younger" than those of relatively inactive subjects. The brains of the less active patients had increased tortuosity produced by vessel elongation and wider expansion curves.

Breakthrough vision system allows bots to zip through crowded rooms

A European research consortium called Decisions in Motion has demonstrated a robot that can zip across a crowded room guided only by what it sees through its twin video cameras. The consortium is now hard at work on a head-mounted system to help visually impaired people get around based on their technology. "Until now, the algorithms that have been used [to allow bots to move through unstructured environments] are quite slow and their decisions are not reliable enough to be useful," says project coordinator Mark Greenlee. "Our approach allowed us to build algorithms that can do this on the fly, that can make all these decisions within a few milliseconds using conventional hardware." If this works as described, it is an enormous advance over existing bot vision systems.

STAT3 protein has key roll in converting normal cells to cancer cells
A protein called STAT3, which stands for signal transducer and activators of transcription, has been found to play a fundamental role in converting normal cells to cancerous cells, according to a new study led by David E. Levy, Ph.D., professor of pathology and microbiology at NYU Langone Medical Center. The study found that STAT3, in addition to its role in the cell nucleus regulating gene expression, is also present in mitochondria and regulates the activity of the electron transport chain in tumors cells. Mitochondria are the basic energy-producing organelles of the cell and are known to be critical for tumor cell metabolism. "These results open the possibility that inhibiting the mitochondrial function of STAT3 could be a promising cancer therapy in the future," adds Dr. Levy.

HIV may use miRNAs to become dormant and escape immune response
Scientists at Burnham Institute for Medical Research (Burnham) looked at miR29 expression levels in infected and uninfected cells and found that miR29 expression was enhanced by HIV-1 infection. Blocking the activity of miR29 with interfering RNA resulted in increased replication and infectivity of the virus. The scientists tested the association of miR29 and HIV-1 by mutating both miR29 and its target region on the HIV virus. When either was altered, miR29s suppression of HIV replication and infectivity was reduced or eliminated. In addition, the team suppressed P-bodies in the cells and noted a similar effect. This suggests that HIV may use miRNAs to become dormant and escape immune response..

Accurate brain-interface possible without penetrating electrodes

Experimental devices that read brain signals have helped paralyzed people use computers and may let amputees control bionic limbs. But existing devices use tiny electrodes that poke into the brain. Now, a University of Utah study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain but don't penetrate it.

"The unique thing about this technology is that it provides lots of information out of the brain without having to put the electrodes into the brain," says Bradley Greger, an assistant professor of bioengineering and coauthor of the study. "That lets neurosurgeons put this device under the skull but over brain areas where it would be risky to place penetrating electrodes: areas that control speech, memory and other cognitive functions."

Protein detecting biochip breakthrough

Biochips are already in widespread use for DNA testing, but not for proteins, because proteins have a defined three-dimensional structure by which they can interact specifically with other molecules and when they bind to a biochip surface the structure can be destroyed. Research scientists at the Fraunhofer Institute have solved this problem. "We have developed a gel - a network of organic molecules - that we can apply to the surface of the biochip," says Dr. Andreas Hollander. "This gel layer [makes] the protein believe that it is in a solution, even though it is chemically connected to the network."

Protein found to prevent cancer from spreading
Researchers at Children's Hospital Boston have found that a protein called prosaposin inhibits metastasis by causing production of factors that block the growth of blood vessels. Cells from localized prostate and breast tumors, which didn't metastasize, secreted high levels of prosaposin, they found, while metastatic tumors secreted very little. Injecting mice with highly metastatic tumor cells with prosaposin, reduced lung metastases 80 percent and lymph node metastases were completely eliminated. Suppressing prosaposin expression in tumor cells caused more metastases. Reasearchers also demonstrated that prosaposin stimulates activity of the well-known tumor suppressor p53 in the connective tissue (stroma) surrounding the tumor. This in turn stimulated production of thrombospondin-1, a natural inhibitor of blood vessel growth (angiogenesis), both in the tumor stroma and in cells at the distant location. "Prosaposin, or derivatives that stimulate p53 activity in a similar manner in the tumor stroma, might be an effective way to inhibit the metastatic process in humans," said Prof. Randoph S. Watnick.

Copper may prevent human 'mad cow' disease

North Carolina State University researchers have discovered a link between copper and the normal functioning of prion proteins, which are associated with transmissible spongiform encephalopathy diseases such as Cruetzfeldt-Jakob in humans or "mad cow" disease in cattle. Prion proteins, or PrPs, are commonly found in brain tissue and throughout the central nervous system. In humans or animals with prion diseases, these proteins deform and aggregate, creating clumps of PrPs that interfere with the nervous system's ability to function normally. A team of NC State physicists, led by Miroslav Hodak and Jerry Bernholc, has found that when PrPs bind with copper in the human body, their structure becomes more stable and less likely to misfold or aggregate. "This stability may play a role in preventing PrPs from misfolding or aggregating," said Hodak. "Which indicates that with prion diseases, copper binding may be beneficial."

Like burrs on your clothes, virus-size capsules stick to cells to target RNA delivery

It is now possible to engineer tiny containers the size of a virus to deliver drugs and other materials with almost 100 percent efficiency to targeted cells in the bloodstream. The technique involves filling the tiny lipid containers, or nanoscale capsules, with a molecular cargo and coating the capsules with adhesive proteins called selectins that specifically bind to target cells. A shunt coated with the capsules is then inserted between a vein and an artery. Much as burrs attach to clothing, the selectin-coated capsules adhere to targeted cells in the bloodstream. After rolling along the shunt wall, the cells break free from the wall with the capsules still attached and ingest their contents. As shown in the image, 36 hours after release nearly every target cell (round gray spheres) has ingested a nanocapsule containing a small-interfering RNA (in red).

A really good video projector built right into your cell phone

Research scientists at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena have developed a mini projector that unlike conventional beamers does not need an additional illumination system. This makes the projector small enough to fit in a cell phone and cuts energy use so much that it does not overtax the battery. "The key component of the projector is an organic display, or OLED," says Dr. Stefan Riehemann, group manager at the IOF. Currently the OLED display produces a monochrome image with a brightness of 10,000 candelas per square meter; for color images the brightness is about half that level. By way of comparison, a computer monitor generates only about 150-300 candelas per square meter.

Why dogs get far more advanced medical treatment than you do
You can chalk it up to politicos catering to religious ignorance. It has been going on since blood transfusion use was delayed for decades because the ignorant Christians in those days thought the soul traveled around the body in the blood stream, so a transfusion would "mix souls." Now they are on again about tiny little bundles of a few dozen undifferentiated cells having "souls," because they could potentially become human beings. As one scientist recently pointed out, with today's technology any cell in your body can become human. So when your preacher stops spewing deadly ignorance from his pulpit for a moment, to scratch his nose, he has actual just engaged in a holocaust, destroying millions of cells that could potentially become human beings.


Various embryonic and adult stem cell therapies in animals are producing simply amazing results. Old dogs with bad hips frolic like puppies. Race horses with injuries come back to become world class winners. One such racehorse, Be A Bono, won 16 out of 24 starts, earned more than 1.3 million in prize money, and was the 2004 World Champion Quarterhorse. All after a stem cell treatment.

Soon, hopefully, Christians will finally get past their ignorance about stem cells. Just like they finally got past their earlier ignorance about blood transfusion. Unfortunately, only after that ignorance had caused millions of unnecessary deaths by blocking blood transfusions for nearly half a century.

People complain about Bush causing the deaths of more Iraqis than Saddam Hussein, but those numbers pail in comparison to the millions forced to suffer pain, suffering and early deaths due to our former president's efforts to gain a few more votes from those suffering from religion-induced ignorance syndrome.

Help stamp out deadly ignorance by helping to spread a far better way of thinking.

Modding your PER3 gene could greatly improve your respond to fatigue
Previous research showed that the PERIOD3 (PER3) gene predicts how people will respond to sleep deprivation. People carry either long or short variants of the gene. Those with the short PER3 variant are resilient to sleep loss, performing well on cognitive tasks after sleep deprivation. However, those with the long PER3 variant are vulnerable, showing deficits in cognitive performance after sleep deprivation. Now new brain imaging studies explains why. The resilient, short gene variant group overcomes the effects of sleep loss by recruiting extra brain structures to compensate. In addition to brain structures normally activated by the cognitive task, these participants showed increased activity in other frontal, temporal, and subcortical brain structures after a sleepless night.

Ensuring that proteins are built correctly is essential to the proper functioning of our bodies, but the quality assurance mechanisms are not fully understood. "Scientists have been puzzled as to how this process makes so few mistakes," says Dr Netta Cohen. So how are errors corrected? Intelligent typesetters would remove the last few letters when they spot an error. The new model suggests how the backward sliding stalls when passing an error, so wrong letters can be snipped off and copying can resume.

Inflation or deflation, which is ahead for America?
I just read a blog post on Mish's economics blog, the last line of which is:
Fears of massive inflation are at this point ridiculous.
Normally, I tend to find Mish's analysis persuasive and have linked to his comments many times in the past, but I fear that by going with a purely credit-based analysis of the situation, he has put himself at risk of a major failure with this prediction. What worries me is that it fails to take into account the requirement that foreign investors maintain their semi-religious faith in dollars. Since there is no practical way all America's debts can ever be paid back, other than in drastically depreciated dollars.

For 40 years the Fed has been able to create far more money annually than Americans have been force to actually experience in inflation.

This has only been possible because of the American dollar's unique status as the world's reserve currency. Due to that unique status, foreign investors & central banks were willing to immediately take many of the dollars the Fed created each year out of circulation, storing them in vaults and mattresses. A thousand dollars stuck in a mattress in India isn't causing any inflation in America. A trillion dollars in a foreign bank vault causes no inflation in America.

No inflation, that is, until someone decides to spend those dollars. Then all that pent up inflation can come roaring back.

After 40 years of dollars as fiat money, with no restraint on America's ability to create them, foreigners are sitting on dollars equal to hundreds of percent points of pent-up inflation, which will all manifest itself at once, if the holders of those dollars ever lose their faith that they represent a good value.

Take away foreign investor confidence in the dollar and suddenly trillions of foreign dollars will start simultaneously chasing whatever commodities and other goods are available for dollars.

This could cause massive inflation to occur, even if as Mish rightly points out, American banks remain completely unwilling to lend money to anyone.

Chinese actions lately make it me think that they are wisely trying to get out in front of the eroding faith problem of the dollar.

If China were able to be perceived by the world's investors as having avoided losses when the dollar crash acceleration occurs. Then their fiat currency might be able to survive the dollar collapse and become the new oil trading unit of exchange, since it is doubtful either the Yen or Euro could survive a dollar collapse. That and China's control of so much of the world's manufacturing plant, could serve to transform China into the world's new dominant economic power, almost overnight.

America became the world's new economic power when, after World War II, we were left with the world's only undamaged manufacturing plant, a strong currency, and a thriving internal market.

Now, told by our elite that we can thrive as a "service economy" we have dismantled our manufacturing plant, allowing China to step in. Today, China is the only country in the world with an undamaged manufacturing plant, a potentially strong currency and a potentially thriving internal market. The monumental stupidity of America's elite has put China in the perfect position to pull the rug out from under America and take over the role of global economic superpower. Winning the war for world leadership, without ever firing a shot.

We could be about to witness a brilliantly executed coup d'etat on the world stage that cuts the legs from under the western world by destroying their severely weakened fiat currencies and leaves China in the world reserve currency driver's seat.

New device designed to detect quantum effect in ordinary objects

Physicists have long wondered if large collections of atoms can exhibit the same quantum effects found in single particles. "It'd be weird to think of ordinary matter behaving in a quantum way, but there's no reason it shouldn't," says Keith Schwab, an associate professor at CalTech. "If single particles are quantum mechanical, then collections of particles should also be quantum mechanical. And if that's not the case - if the quantum mechanical behavior breaks down - that means there's some kind of new physics going on that we don't understand." Now, researchers have developed a new tool that can be used to search for quantum effects in an ordinary object.

The BRIT1 protein plays a key role in early detection of DNA damage
Like a mechanic popping open the hood of a car to get at a faulty engine, the BRIT1 tumor-suppressing protein allows cellular repair mechanisms to pounce on damaged DNA by overcoming a barrier to DNA access. A research team led by scientists at The University of Texas M. D. Anderson Cancer Center shows that BRIT1 connects with another protein complex to relax DNA's tight packaging at the site of the damage, allowing the faulty DNA to be repaired. The team showed that normal BRIT1 aids repair of double-stranded DNA breaks by allowing access to two repair pathways: homologous recombination (HR) and non-homologous end-joining (NHEC).

Highly flexible and configurable container living pods

These modular container houses offer a high degree of flexibility. These living pods can be easily modified and regrouped to change the nature of your dwelling. The structural rigidity in the metal frame and corrugation give greater strength than standard timber and steel construction, allowing easy stacking and joining in numerous possible configurations for habitats both large and small. Construction time from start to finish is significantly reduced through prefabrication of about 80% of the structure. Once a plan has been selected, the factory prepares the units by cutting for windows, doors or removing sides. Windows, flooring, and other finish materials are applied easily through use of standard dimensions and pre-assembled framing.

Could solar panels filled with gasoline-secreting diatoms replace petroleum?
Scientists in Canada and India are proposing a surprising new solution to the global energy crisis: "milking" oil from the tiny, single-cell algae known as diatoms, renowned for their intricate, beautifully sculpted shells that resemble fine lacework. Abstract: Here, we review a simple line of reasoning: (a) geologists claim that much crude oil comes from diatoms; (b) diatoms do indeed make oil; (c) agriculturists claim that diatoms could make 10 to 200 times as much oil per hectare as oil seeds; and (d) therefore, sustainable energy could be made from diatoms.

Keynesian bubble economics is destroying our lives
John Maynard Keynes did more damage to our civilization than any other pseudo-scientist.

Prior to the adoption of Keynes ruinous ideas, many nations had money with the more stable, intrinsic value of being backed by precious metals and market forces, not politicos running central banks, controlled interest rates. In those days, the value of your money did not erode away and interest tended to give you a reasonable return on your capital.

Up until the end of the 1960's in the USA, you could still work hard, put your money in the bank or Government Savings Bonds, and be assured of a comfortable retirement.

Then Keynes' fiat money system was imposed on America by politicos who wanted to buy votes by handing out freebies at home, while simultaneously taking on the costly role of creating an American world economic empire. This caused the buying power of the dollar to plunge. For fifty years the price of a Hershey bar at the neighborhood store where I grew up was 5 cents. Then when America replaced our gold-backed money with Keynesian fiat money, the price of that Hershey bar skyrocketed: [1969] 10 cents, [1974] 15 cents, [1977] 20 cents, [1978] 25 cents, [1982] 30 cents, [1983] 35 cents, [1986] 40 cents, [1991] 45 cents, [2002] 59 cents, [2009] 89 cents. Along with the price of nearly everything else we all buy regularly.

You could no longer simply work hard, save your money and be assured of a comfortable retirement. Because politicos were inflating away the value of your savings at a rapid clip, and keeping interest rates so artificially low that you couldn't keep up.

Low interest rates, easy credit, massive creation of money through the printing press and fractional reserve lending had to be put into place to keep all the negative effects of Keynes ideas from being seen, to keep an economic system being slowly strangled to death, walking. But like any Frankenstein, our undead economy was unable to walk smoothly, but instead had to lurch from one hastily inflated economic bubble to the next, with each new bubble seeming to take more monetary stimulus to inflate than the last one.

Without your knowledge, you had been robbed of the ability to save your money for a comfortable retirement. This was no longer an option, since fiat money inflation would destroy the buying power of your savings to quickly and interest rates on savings had to be kept artificially low, to keep our dying economy walking.

In order to protect the buying power of our savings, we were all forced into becoming speculators. We had to keep taking on more and more risky investments keep our dreams of retirement from being stolen by the politicos pushing the new Keynesian bubble economic system that gave them far more power at your expense.

Wall Street's big firms profited as never before from selling investors more speculative investments and joined with Washington to keep the destructive Keynesian delusion alive.

Eventually, things got to the point that what I have called the king has no clothes recognition avoidance mechanism began to take effect. We in the west knew that our portfolios would be utterly wiped out if any of us said anything about the fact that Lord Keynes was prancing around the kingdom not wearing any clothes. So we all tightly closed our eyes to avoid seeing what had become obvious to any thinking person, that all the Keynesian clowns running our Treasury Department and Central Banks were running around stark naked.

The work of Lord Keynes supports the empowerment of economic and political elites at the expense of ordinary workers and investors, who's ability to save and retire is severely impaired.

Economists are richly rewarded by these political and economic elites for supporting Keynes and that insidious feedback loop is the only reason Keynes ruinous economic ideas persist.

Now though, the voices of reason, pointing our that Lord Keynes' followers are wearing no clothes are growing stronger.

Recently, Dr Xu, who has a doctorate from the University of California and was formerly managing director of the China's biggest investment bank began calling western leaders to account for remaining stuck in the failed Keynesian bubble economy mind set, saying: "It's time to announce Keynesianism's failure, time to announce the emperor Lord Keynes has no clothes." He went on to accuse the west many Keynesian politicos of "casting a moral verdict without seeming to care about truth or logic".

At least in Asia, reason seems to be returning. In the west, I fear we have more pain to endure before we again begin to see the light.

Discovery of the cell's water gate can provide cancer control technique

Cells must be able to regulate the flow of water in and out in order to maintain their form and size. This regulation is carried out by special proteins known as aquaporins and inhibiting their function has been shown to dramatically reduce the spread and growth of tumors. Now researchers at the University of Gothenburg have determined the three-dimensional structure of the aquaporin in yeast. "Our study shows that the amino-terminal extensions in yeast act as a gate that can be opened and closed depending on how much water the cell must release or absorb", says Professor Karin Lindkvist. Since human and yeast aquaporin are similar this model could be used to develop human cancer inhibitors.

Nanoparticles are about to put an end to era of painful chemotherapy

UCF researcher's say that their nanoparticles could soon put an end to the era of painful and primitive chemotherapy.

University of Central Florida Assistant Professor J. Manuel Perez used a drug called Taxol for their cell culture studies, because it is one of the most widely used chemotherapeutic drugs. Taxol normally causes many negative side effects because it travels throughout the body and damages healthy tissue as well as cancer cells. However, the Taxol-carrying nanoparticles engineered in Perez's laboratory are designed so they carry the drug ONLY to the cancer cells, allowing targeted cancer treatment without harming any healthy cells. This is achieved by attaching a vitamin (folic acid) derivative that cancer cells like to consume in high amounts.

The bottom line is much better treatment results with none of the normal chemotherapy caused damage to normal cells that makes chemo such a painful ordeal for many cancer patients.

How to keep the Earth habitable for an extra 1.3 billion years (65 million more human generations)

Scientists at Caltech have figured out how to counteract the changes in our sun to keep the Earth habitable for humans for another 1.3 billion years. That is long enough to give another 65 million generations of humans the opportunity to be born on humanity's home world.

As the sun has matured over the past 4.5 billion years, it has become both brighter and hotter, increasing the amount of solar radiation received by Earth, along with surface temperatures. Earth has coped by reducing the amount of carbon dioxide in the atmosphere, thus reducing the warming effect. The pressure of carbon dioxide in the atmosphere has dropped some 2,000-fold over the past 3.5 billion years.

The problem, says Caltech Professor Joseph L. Kirschvink is that "we're nearing the point where there's not enough carbon dioxide left" in the atmosphere to regulate temperatures by lowering it. Essentially, even taking atmospheric CO2 to zero will not be enough to overcome the Sun's increased heat generation. The solution for preventing Earth from becoming uninhabitable due to our Sun's increasing energy output, say Kirschvink and his collaborators, is to reduce substantially the total pressure of the atmosphere itself, by removing massive amounts of molecular nitrogen, the largely nonreactive gas that makes up about 78 percent of the atmosphere. This would regulate the surface temperatures and allow carbon dioxide to remain in the atmosphere, to support life, and could tack an additional 1.3 billion years onto Earth's expected human habitability lifespan.

All the world's politico's quibbling over carbon taxes won't even make a dent in the needed offset to the Sun's increased output. Scientists are going to have to figure out how to engineer a much more robust thermostat for our planet, if we want that 65 million generations of human to get that opportunity to be born on our home world.

Replacement of lost MicroRNA can stop cancer in its tracks
A new study suggests that delivering small RNAs, known as microRNAs, to cancer cells could help to stop the disease in its tracks. microRNAs control gene expression and are commonly lost in cancerous tumors. Researchers have shown that replacement of a single microRNA in mice with an extremely aggressive form of liver cancer can be enough to halt their disease. They delivered the microRNA to the mice using a virus that has been applied in other forms of gene therapy. That so-called adeno-associated virus (AAV) is particularly good at targeting new genetic material to the liver. "Mice given the control virus showed no change in the growth rate of their tumors and within three weeks, the cancer had taken over," said Joshua Mendell of Johns Hopkins University School of Medicine. "When we gave them the microRNA-carrying virus, some animals showed essentially complete regression of their tumors." In other cases, he said, the tumors were much smaller and far fewer.

Stress really does make your hair turn gray
Those pesky graying hairs that tend to crop up with age really are signs of stress. Researchers have discovered that the kind of "genotoxic stress" that does damage to DNA depletes the melanocyte stem cells (MSCs) within hair follicles that are responsible for making those pigment-producing cells. Rather than dying off, when the going gets tough, those precious stem cells differentiate, forming fully mature melanocytes themselves. Anything that can limit the stress might stop the graying from happening, the researchers said.

Pay teachers more, grades stay poor, but pay kids to score and off they soar
Paying kids to learn boosts math and English performance test scores by far more than raising teacher's pay. At PS 188 on the Lower East Side, 76 percent of fourth-graders met or exceeded state benchmarks in English -- 39.6 percentage points higher than last year, when the kids were in third grade. While efforts by some school districts a few years back to see if, as teacher's unions claimed, paying teachers more would greatly improve scores boomed utterly, with results continuing down hill after the raises.

If you put a school with the latest learning software bots combined with automated financial incentives to students for good performance up against a school run in the traditional way. Odds are that the bots and incentives would produce dramatically better results, while costing taxpayers considerably less.

Of course, such a test is unlikely to ever take place in an environment where our educational decision making is so heavily influenced by teachers associations entirely focused on their own narrow self interests at the expense of the futures of our kids and our nation.

Further, immediately prior to a switch in behavior, the FPC (frontopolar cortex) exhibited a distinct pattern of connectivity with the parietal cortex, an area of the brain that is known to be active during cued behavior switching. "This suggests that when the FPC has recruited sufficient evidence to support a behavioral switch, it engages the parietal cortex to implement the switch," offers Dr. Boorman.

Spectrally narrow electroluminescence of our QD-LEDs is tuned over the entire visible wavelength range from λ = 460 nm (blue) to λ = 650 nm (deep red). By printing close-packed monolayers of different QD types inside an identical QD-LED structure, we demonstrate that different color QD-LEDs with QDs of different chemistry can be fabricated on the same substrate.

The ultimate clean lean mean electric riding machine

Drawing inspiration from BMW's DNA with a focus on their efficient dynamic theme, the BMW X bike by designer Jacobus Marx is a zero-emission electric bike concept for the active urban motion pod of the near future. This motion pod concept is propelled by two 80KW in-wheel electric motors and uses super-capacitors to keep the bike lean and super fast to charge. It can run in an elevated mode at city speeds or sink down close to the ground for a higher speed ride.
