Engineered cells could usher in programmable cell therapies
Researchers at Brigham and Women’s Hospital (BWH) have engineered cells that could solve one of the key challenges associated with the procedure: control of the cells and their microenvironment following transplantation. Researchers at Brigham and Women's Hospital have engineered human mesenchymal adult stem cells to contain tiny depots that can influence the behavior of the cells and those surrounding them, including their survival, differentiation, or production of a therapeutic proteins. These depots can slowly release a variety of agents to influence the behavior of not only the cells containing the depots, but also those close to them and even much farther away. The team demonstrated this by prompting mesenchymal stem cells to differentiate into the cells that make bone.
“Ten to fifteen years from now, people will visit cell infusion centers to receive routine therapy for multiple diseases and tissue defects,” predicts Karp, who also holds appointments through Harvard Medical School, Harvard Stem Cell Institute, and the Harvard-MIT Division of Health Sciences and Technology (HST). For example, a person who has had a heart attack could be infused with cells that could help stimulate regeneration of new heart cells to replace those that have died and prevent eventual heart failure.
They are in the process of translating the work to animals. “If it works in vivo, it could have a significant impact globally on cell therapy."

Towards Mastery of Carbon Nanotube Growth
Carbon nanotubes could enable plastics to be manufactured that are ten times stronger than the strongest materials available today. Mastering carbon nanotube growth would enable high volume and lower cost production of longer and stronger carbon nanotubes so that the vision of using carbon nanotubes for more applications in society can be realized. Currently only about one thousand tons per year of carbon nanotubes are produced.

Larger city have a higher wage gap with the critical mass to support key technologies and industries
A University o Rochester study shows that overall up to one-third of the growth in the wage gap between the rich and the poor is driven by city size independent of workers' skills
The larger the city, the wider the wage gap among its workers. In other words, the country's largest cities, New York, Los Angeles and Chicago, are home to the greatest extremes in incomes, while midsized cities experience relatively less wage inequality and rural areas the least. Larger metropolitan areas, more so than their smaller counterparts or rural areas, have experienced rapid growth in wages within all skill levels.

Universal Flu Vaccine human clinical trials reports success
UK Guardian - Oxford University human clinical trials that began in 2008 have reported successful results for a universal flu vaccine. A universal vaccine would save the time and money now needed to create vaccines to fight whatever particular virus has emerged in any year. The UK government spends almost $2 billion/year in preparing for the swine flu outbreak of last winter. There is also the potential to save the 250,000 to 500,000 lost worldwide because of the flu in a typical year. There is also the risk of flu pandemics which can kill millions in one year.
The results showed that the vaccine worked as planned. "Fewer of the people who were vaccinated got flu than the people who weren't vaccinated," said Gilbert. "We did get an indication that the vaccine was protecting people, not only from the numbers of people who got flu but also from looking at their T-cells before we gave them flu. The people we vaccinated had T-cells that were more activated. The people we hadn't vaccinated had T-cells as well but they were in a resting state so they would probably have taken longer to do anything. The volunteers we vaccinated had T-cells that were activated, primed and ready to kill. There were more T-cells in people we vaccinated and they were more activated." Gilbert has now sent her results to a scientific journal.
Hill said the trial proved two important things about the vaccine. "It showed that it was safe; and giving people flu virus in the presence of lots of T-cells induced by the vaccine was absolutely fine.
"The [traditional flu] vaccine efficacy is 70-80% of young people, but only 30-40% in old people," said Hill. "What we'll do is an efficacy trial in the elderly and try to improve that 30-40% to hopefully double that."

Hydro Turbine based Basking Shark is 40% more efficient than Conventional turbines
A new turbine design underwent 200 hours of testing at the University of Michigan's Marine hydrodynamics lab, team calculated that the prototype already improves power output of a single turbine blade by 40%. Studying the bumpy protrusions on the fins of humpback whales has already led to more efficient wind and tidal power turbines and now nature is once again the source of inspiration for a new and more efficient hydroelectric turbine. The latest source of biomimicry is the basking shark, which industrial design student Anthony Reale has borrowed from to create "strait power," a water-powered turbine generator that tests have shown is 40 percent more efficient than current designs.
Guest post by Friedlander - Eighteen Ideas For Liberty—18 Proposed Constitutional Amendments for more rapid economic development
Preamble from Brian Wang- this is a long article and it is on the topic of politics and policy. It does not relate to science and technology, so please skip this article if you do not want to read things that are not science and technology or if a libertarian take on politics and policy and things like constitutional amendments would be annoying to you. This does not represent my politics per se but I am willing to let my guest Joseph have this forum to explore a set of ideas. Joseph has contributed other articles on technology and has helped to refine the concept of the nuclear cannon for space launch.
Again a warning- if reading anything with a libertarian bias makes you angry then do not bother going any further.
Answer to the question - why is his here ? Joseph has written other technical articles for this site and we have worked together on my nuclear space cannon. Thus I am giving him leeway in his writing some other articles. ie he paid his dues.
Guest post by Joseph Friedlander
Note-- I (from this point on Joseph's writing) am not 100% about the wording of these suggested amendments--any real amendment would --but I am serious that they serve as a springboard for discussion of the issues concerned. Right now open wounds are neglected in our country. It’s time to heal them.
1. Plain English amendment--- for any such court case in which a citizen postulates that a law under which he is challenged is too complex for an ordinary citizen to understand, a statistically valid jury shall be seated with intelligence in the lower half of the population (33rd percentile—since 50% would set the bar too high for those functional citizens below average). This jury shall be given statement by statement with multiple meanings suggested by the defense. Unless there is unanimity of consensus by ALL answers of the jury that the law is plain (they all give the same answers on their tests) the law as drafted shall be suspended and returned to the legislature for rejection or redrafting. Any attempt by prosecutors to give an answer key shall result in legal disbarment for life.

Why do some countries economies grow faster ?
MIT is reporting growing acceptance of economic growth theories of César Hidalgo and Ricardo Hausman.
The standard theoretical framework for development economics was established more than 50 years ago by the MIT economist Robert Solow, who developed a mathematical model that predicts countries’ economic growth on the basis of labor and capital (the tools of production); subsequent work expanded the model to include factors such as land and human capital (expert knowledge). The model proved highly influential, ultimately earning Solow the 1987 Nobel Prize in economics.
Hidalgo argues, by lumping together a huge variety of resources under the general heading “capital,” it can obscure distinctions that are crucial to an accurate understanding of countries’ economies. In a series of papers cowritten with Ricardo Hausmann, director of the Center for International Development at Harvard’s Kennedy School of Government, Hidalgo has argued that, indeed, the best predictor of a country’s future economic health is not the magnitude but the diversity of its production capacity.

AOL buys Huffington post for $315 million
AOL has bought the Huffington Post for $315 million.
In Dec, 2010, 24-7 Wall Street valued the Huffington Post at $150 million and as the second most valuable blog after Gawker.
This is not an impact on the future, but is a minor data point that seems to confirm the relative accuracy of the valuation estimates made by 24-7 Wall Street on private blogs. The difference between the AOL purchase price and the valuation estimate is the buyout premium.

Nanolasers grown on silicon
Schematic of a nanopillar laser monolithically integrated onto silicon, illustrating its InGaAs core and GaAs shell. The higher-bandgap GaAs shell protects carriers from non-radiative surface recombination, which is critical for room-temperature operation
Nature Photonics - Nanolasers grown on silicon
Nature Photonics - Nanolasers grown on silicon
The integration of optical interconnects with silicon-based electronics can address the growing limitations facing chip-scale data transport as microprocessors become progressively faster. However, until now, material lattice mismatch and incompatible growth temperatures have fundamentally limited monolithic integration of lasers onto silicon substrates. Here, we use a novel growth scheme to overcome this roadblock and directly grow on-chip InGaAs nanopillar lasers, demonstrating the potency of bottom-up nano-optoelectronic integration. Unique helically propagating cavity modes are used to strongly confine light within subwavelength nanopillars despite the low refractive index contrast between InGaAs and silicon. These modes therefore provide an avenue for engineering on-chip nanophotonic devices such as lasers. Nanopillar lasers are as-grown on silicon, offer tiny footprints and scalability, and are thus particularly suited to high-density optoelectronics. They may ultimately form the basis of future monolithic light sources needed to bridge the existing gap between photonic and electronic circuits

HyperV magneto-inertio fusion using rail guns
HyperV Technologies is dedicated to producing the world’s first commercially viable fusion reactor technology. Our research will result in the development of a controlled hot fusion reactor that is scalable to provide between 100 MW and 2,000 MW of clean base load electric power. The flexibility of the reactor size will enhance the robustness of the global power grid by enabling reliable base load power to be widely distributed through out an existing network.
HyperV Technologies is pursuing a unique “pulsed ignition” approach to fusion that has the promise to dramatically reduce the level of complexity, reliability and maintainability of the reactors. The HyperV approach will use an array of plasma jets to drive a pulsed implosion upon centimeter sized magnetized fuel targets in microsecond timescales.

US Dollar Decline as China Becomes Importer in 2013-2016
Bloomberg - China will curb its reliance on exports sooner than the U.S. can cut its budget and external deficits, removing a support from the dollar that will unsettle currency markets, Morgan Stanley's Stephen Roach said. "In the next three or five years China will move aggressively to increase its private consumption and reduce its surplus saving," Roach, who is non-executive chairman of Morgan Stanley Asia Ltd., said in an interview in Oslo yesterday.

Researchers find simple, inexpensive method to produce silicon wires for sensors, batteries and solar cells
Molten droplets of copper, at top, dissolve silicon out of a surrounding silicon-rich gas, and then the silicon precipitates out at the bottom of the drop to gradually build up a silicon microwire. This microscope image has had color added for clarity. Image courtesy of Tonio Buonassisi
Microwires made of silicon — tiny wires with a thickness comparable to a human hair — have a wide range of possible uses, including the production of solar cells that can harvest much more sunlight for a given amount of material than a conventional solar cell made from a thin wafer of silicon crystal. Now researchers from MIT and Penn State have found a way of producing such wires in quantity in a highly controlled way that could be scaled up to an industrial-scale process, potentially leading to practical commercial applications.

SENS looks at rejuvenating immunity through ablation
The degenerative aging of the immune system is responsible for an enormous burden of disease and disability, from the pain of recurrent Herpes zoster and postherpetic neuralgia, to elevated rates of chronic urinary tract infections, to complications in wounds, pressure sores, ulcers, and surgical incisions. Most prominently, it underlies the meteoric rise in mortality from respiratory infections with age: influenza, pneumonia, and septicemia rise from being negligible causes of death in healthy middle-aged adults in the USA, to emerge amongst the top 10 causes of death in adults over the age of 55, with mortality rates climbing with each successive year of aging. And in addition to increasing the morbidity and mortality specifically attributable to particular infections, the dysregulation of immune function by immunosenescence is widely acknowledged to exacerbate multiple chronic age-related illnesses, and to contribute to functional decline and frailty in aging people
Note: also there has been work that suggests that super-strengthening of the immune system could be paths to curing cancer and HIV Aids.

Quickly reviewing the scale of money spent on different energy
The IEA world energy outlook discusses the money spent subsidizing renewables and all other types of energy
Energy is not cheap. There is a recent estimate that $25 trillion will need to be put into building what is needed to meet global energy demand increases between 2010 and 2030. A lot of that money will still go to more coal power plants. Perhaps one or two trillion will go to conventional nuclear power. 120 nuclear fission reactors could be built by 2020 for about $300-500 billion.

Z Pinch roadmap to petawatts and beyond
Sandia's machine was dismantled in July 2006 for an upgrade, including the installation of newly designed hardware and components and more powerful Marx generators.
The refurbishment was completed in October 2007. The newer Z machine can now shoot 27 million amperes (instead of 18 million amperes previously) in 95 nanoseconds. The radiated power has been raised to 350 terawatts and the X-ray energy output to 2.7 megajoules.
Sandia's roadmap includes another Z machine version called ZN (Z Neutron) to test higher yields in fusion power and automation systems. ZN is planned to give between 20 and 30 MJ of hydrogen fusion power with a shot per hour using a Russian Linear Transformer Driver (LTD) replacing the current Marx generators. After 8 to 10 years of operation, ZN would become a transmutation pilot plant capable of a fusion shot every 100 seconds.
The next step planned would be the Z-IFE (Z-inertial fusion energy) test facility, the first true z-pinch driven prototype fusion power plant. It is suggested it would integrate Sandia's latest designs using LTDs. Sandia labs recently proposed a conceptual 1 petawatt (10^15 watts) LTD Z-pinch power plant, where the electric discharge would reach 70 million amperes.

Smartphones of the future
This is a summary of how the smartphones of 2015 and 2020 could change.
1. More AI and speech recognition and better gesture control
2. Context awareness and more integration with sensors and other phones
3. Different display options (rollable displays, better picoprojectors and more)
4. Increased processing power and better energy efficiency and management
MIT is adding more Artificial Intelligence into Smartphones
A new system from the Computer Science and Artificial Intelligence Laboratory’s Spoken Language Systems Group automatically combs through users’ reviews, extracting useful information and organizing it to make it searchable.
Two prototypes of the MIT system, both with speech interfaces, can currently be found online. One takes commands in Chinese and contains information on businesses in Taipei, Taiwan, and the other takes commands in English and includes information on businesses in Boston.

Europe plans to spend one trillion euros by 2020 for energy grid upgrades and nuclear included as a core part of the plan
The European Commission, steering EU energy policy, says about 1tn euros (£850bn; $1.4tn) will have to be invested over the next 10 years to modernise energy generation and supply. The EU has set itself a "20-20-20" goal: a 20% cut in emissions of greenhouse gases by 2020, compared with 1990 levels; a 20% increase in the share of renewables in the energy mix; and a 20% cut in energy consumption
North-south energy connections are seen as a priority - to link the Baltic energy market to the rest of Europe and to help develop South-East Europe, where many people live in energy poverty, spending a relatively high amount of income on fuel bills. A high-tech power grid -- estimated to cost about 200 billion euros -- to carry wind power from the north and solar power from the Mediterranean to central cities such as Paris and Prague.

Lawrenceville Plasma Physics ruggedizing research nuclear fusion machine
Lawrenceville Plasma Physics is ruggedizing their dense plasma focus fusion machine. A thicker tungsten rod will now require a much bigger spark plug and the widening of the hole in the electrode plates. They are doing this to end mechanical and electrical breakdown of the insulators. They want to press on to 45 kilovolts.
The fourth of eight goals is to increase the charging potential on the machine, by 5 kV steps, up to the full capacity of 45 kV and in the process achieve a peak current of about 2 million amps with deuterium.
Increasing the current (by increasing the voltage is where a lot of performance improvement is expected.
Scaling with increased current, I^5 scaling to 1.4 MA (55 times more power)
Optimization of axial magnetic field (3 times more power)
Scaling with increased current, I^4 scaling from 1.4 MA to 2.8 MA (16 times more power)
So far LPP has been achieving much faster scaling, almost I^7.
Changing the fuel to pB11 should enable an increase of 160 times (higher reaction rate at 600 keV, more energy per reaction, and more compression)

Bioengineered veins could help patients needing bypass surgery, dialysis
Vein drain: Using human cells, scientists have grown shelf-stable blood vessels, like this six-millimeter-diameter model, that they hope to eventually see used as grafts for heart surgeries and hemodialysis. Credit: Science/AAAS
New research published in the current issue of the journal Science Translational Medicine demonstrates the capability of tissue-engineered vascular grafts that are immediately available at the time of surgery and are less likely to become infected or obstructed. The bioengineering method of producing veins shows promise in large- and small-diameter applications, such as for coronary artery bypass surgery and for vascular access in hemodialysis.
Humacyte, a Morrisville biotechnology company, worked with East Carolina university researchers to develop the veins.
The researchers have grown vessels using human cells for the first time. They used the vessels to link an artery and a vein in baboons, creating a structure called a fistula to mimic the setup required by hemodialysis patients, who have a needle injected into such a link two or three times a week to get their blood filtered. Also, while previous versions of the vessels required a wait of several weeks while the insides of the vessels were "personalized" with some of the patient's own cells, a process that makes them less likely to clog, these hemodialysis vessels did not need that treatment. They could potentially be immediately available to the patients

A cheap engine using sound waves possibly commercial in 2012
Etalim, based in Vancouver, Canada, says its engine, roughly the size of a basketball, could improve the economics of electricity production for the cogeneration of power and heat in homes, and as a way to harness the heat produced at concentrating solar collectors.
The company has ambitious goals. A first prototype, completed last year, demonstrated that the concept works, but relatively low heat was used, so its efficiency was only 10 percent. A second prototype that aims for 20 to 30 percent efficiency at 500 °C is expected this spring. A commercial product with 40 percent efficiency running at 700 °C is targeted for 2012. It will initially be sold as a cheaper and longer-lasting competitor to fuel cells used for residential cogeneration. The company believes it can manufacture the engine for less than $1 per watt, and has a long-term target of 15 cents per watt, which would make it less expensive than a comparable internal combustion engine.

Iraq oil production could be 25-35% higher than 2010 in 2011 and the plans for Rumaila, West Qurna and Zubair oilfields
Extended the US State department graph of iraq oil production and exports with the new numbers and forecasts. Reaching 3 million barrels per day (mbpd) would be 25% higher (590,000 bpd increase) than the 2010 production and 3.26 mbpd (850,000 bpd increase) would be 25% higher than 2010.
Iraq's exports surged to a postwar record of 2.16 million b/d in January The semiautonomous Kurdistan region had been due to resume exports on Feb. 1 at a rate of 100,000 b/d, but in the event did not. And when exports do resume, Iraqi oil sources see initial rates closer to 70,000 b/d. Kurdish region's Tawke oilfield is expected to rise to 50,000 barrels per day in the next two to three days.
International oil companies involved in Iraq's oil opening are expected to add a further 300,000 b/d to production this year, hoisting the total to 3 million b/d -- which would allow for exports of about 2.4 million b/d. Most of the incremental oil will come from work by BP and China National Petroleum Corp. at Rumaila, an Eni-led group at Zubair and -- later in the year -- from Exxon Mobil and Royal Dutch Shell at West Qurna-Phase 1.
The Iraqi oil ministry has a target of 3.26 million barrels per day by Dec 31, 2011
The quick gains at Rumaila and Zubair entitle the contractors to claw back their costs and get paid.

Boosting body’s immune response may hold key to HIV cure
Australian scientists have successfully cleared a HIV-like infection from mice by boosting the function of cells vital to the immune response.
A team led by Dr Marc Pellegrini from the Walter and Eliza Hall Institute showed that a cell signaling hormone called interleukin-7 (IL-7) reinvigorates the immune response to chronic viral infection, allowing the host to completely clear virus. Their findings were released in today’s edition of the journal Cell. Dr Pellegrini said the research had provided excellent ideas for new therapies that could target and boost host immune cells to fight disease, rather than targeting the disease itself. “The findings could help to develop drugs that target some of these host molecules, such as SOCS-3, and turn them off for very short, defined periods of time to reinvigorate the T cells, allowing them to regroup to fight infection,” he said.

Berkeley Lab Scientists Image Plasmonic Nanofields with nanoscale resolution
Scientists at Berkeley Lab’s Molecular Foundry have developed a web-based imaging toolkit designed for researchers studying plasmonic and photonic structures. This open-source software is available at http://www.nanohub.org.
Berkeley Lab team used their innovative imaging concepts to visualize plasmonic fields with nanoscale resolution. By imaging fluorescence from gold within the bowtie and maximizing the number of photons collected from their bowtie devices, the team was able to glean the position of plasmonic modes—oscillations of charge that result in optical resonance—just a few nanometers apart.

A new way of splitting layered materials to give atom thin "nanosheets" has been discovered. This has led to a range of novel two-dimensional nanomaterials with chemical and electronic properties that have the potential to enable new electronic and energy storage technologies. The new method is simple, fast, and inexpensive, and could be scaled up to work on an industrial scale. The work will open up over 150 similarly exotic layered materials – such as Boron Nitride, Molybdenum disulfide, and Bismuth telluride – that have the potential to be metallic, semiconducting or insulating, depending on their chemical composition and how their atoms are arranged. This new family of materials opens a whole range of new "super" materials.

Kepler Telescope related - what is the probability of locating a planet in relation to its major-axis (orbit radius) from various stars
Reader Goat guy used the Monte Carlo estimation method to determine for the NASA Kepler Space telescope:
What is the probability of locating a planet in relation to its major-axis (orbit radius) from various stars?
So first off - I can tell you that anyone who claims "1%" detection probability is pulling that number "statistically" out of his arse. It is just as good as 0.1%, 0.5%, 2% or 5%. The reason all comes down to the very strong link between detection probability and orbital radius. Here are the results:

Google Android 3.0 Honeycomb for Tablets
Google demonstrated Honeycomb's features, as well as new apps developed by partners for the new operating system, using Motorola Xoom tablets, which are set to become available through Verizon in March. The tablet's dual-core processor is more efficient and powerful than previous mobile chips, allowing slick 3-D graphics, among other features.
Aric Cheston, a creative director with Frog Design, says some changes unveiled by Google do challenge Apple. For example, an upgrade to the Android market makes it possible to browse Android apps using a web browser and with a few clicks have that app it automatically install on their tablet remotely. Honeycomb is also tightly integrated with Google's web services - for example the camera has one-click upload to Youtube.

There is still fighting in Egypt
A Foreign policy analysis explains why Mubarak is going to win by Robert Springborg is a professor of national security affairs at the Naval Postgraduate School
While much of American media has termed the events unfolding in Egypt today as "clashes between pro-government and opposition groups," this is not in fact what's happening on the street. The so-called "pro-government" forces are actually Mubarak's cleverly orchestrated goon squads dressed up as pro-Mubarak demonstrators to attack the protesters in Midan Tahrir, with the Army appearing to be a neutral force. The opposition, largely cognizant of the dirty game being played against it, nevertheless has had little choice but to call for protection against the regime's thugs by the regime itself, i.e., the military. And so Mubarak begins to show us just how clever and experienced he truly is. The game is, thus, more or less over.

Spacex proposes integrated rocket powered launch abort
Unlike traditional emergency systems, called a tractor design by engineers, SpaceX wants to build an integrated launch abort rocket to provide escape capability throughout the rocket's flight to orbit. Tractor designs used by the U.S. Mercury and Apollo programs were thrown away a few minutes after liftoff, as soon as their boosters cleared the atmosphere.
The integrated system would be part of the Dragon capsule, staying with the spacecraft during months at the International Space Station and returning to Earth at the end of a normal flight. It could even be fired for a rocket-assisted touchdown on land, bringing astronauts home to a soft landing closer to recovery teams.
After the Space Shuttle retires next year, NASA will be totally dependent on the Russian Soyuz to carry astronauts to and from the International Space Station for a price of over $50 million per seat. Spacex is proposing to do it for about $20 million per seat.

NASA Kepler Space telescope finds 1202 possible exoplanets from 1/400th of the sky
NASA's Kepler space telescope has found 1202 possible exoplanets. The expectation is 90% of those will be confirmed. The Kepler telescope surveys only one four-hundredth of the sky, the numbers extrapolated to some 20,000 habitable-zone planets within 3,000 light-years of Earth.
Of the new candidates, 68 are one-and-a-quarter times the size of the Earth or smaller — smaller, that is, than any previously discovered planets outside the solar system. Another 50 of these so-called exoplanets are in the habitable zones of their stars, where temperatures should be moderate enough for liquid water, the essential stuff for life as we know it; two of these are less than twice the size of Earth.

Mubarak sends goons to crush Egyptian uprising
UK Guardian - Egyptian president's regime orchestrates bloody battles in Tahrir Square against protesters seeking his removal from power.
A significant number of the pro-Mubarak supporters are probably plain clothes secret police or loyal to Mubarak army units.
Sydney Morning Herald - The protesters, who have made Tahrir Square the epicentre of their anti-government demonstrations, said secret police were among the Mubarak supporters who took over the square. ''It seems to have been heavily choreographed,'' a Guardian journalist, Peter Beaumont, reported from the scene. ''It's quite clear some of these people came prepared for a violent confrontation. You can't help feeling that it has all been heavily co-ordinated. It's an extraordinary turnaround.''
El Baradei threatened violence and bloodshed and implied the death of Mubarak if Mubarak did not leave by Friday. Mubarak seems willing to test if El Baradei can back the threat up.
Using clubs, bats, knives and even homemade spears, pro-Mubarak demonstrators charged the square at just before 2pm. They had been gathering for several hours 800 metres from the square on the Nile Corniche, outside the state television station

Twenty times more efficient electric vehicle with a top speed of 375 mph
Wired - Swiss company Acabion is working on the GTBO VIII “da Vinci,” a $15 million fully electric vehicle with a top speed of 375 mph that Acabion claims is 20 times more efficient than current Electric cars. It’s as much a work of art as a proof of concept: Maskus says that for production vehicles, the price will come down “by reducing the overall exclusivity and by reducing the power from our today’s top-of-the-line 700 horsepower or 800 horsepower to standard regions, and of course by mass production.
Acabion, a Swiss company led by former Porsche, BMW and Ferrari engineer Peter Maskus, is building vehicles it claims will be the “certified successor of cars.” They’re “streamliners” — upgraded land-speed racers that look like motorcycles wrapped in fighter jets, and Maskus hopes to have them in the hands of consumers by 2015.

NASA's NEOWISE Space telescope Completes Scan for Asteroids and Comets
During its one-year mission, NASA's Wide-field Infrared Survey Explorer, or WISE, mapped the entire sky in infrared light. Among the multitudes of astronomical bodies that have been discovered by the NEOWISE portion of the WISE mission are 20 comets. Image credit: NASA/JPL-Caltech/UCLA
NASA's NEOWISE mission has completed its survey of small bodies, asteroids and comets, in our solar system.The mission's discoveries of previously unknown objects include 20 comets, more than 33,000 asteroids in the main belt between Mars and Jupiter, and 134 near-Earth objects (NEOs). The NEOs are asteroids and comets with orbits that come within 45 million kilometers (28 million miles) of Earth's path around the sun.
NEOWISE is an enhancement of the Wide-field Infrared Survey Explorer, or WISE, mission that launched in December 2009. WISE scanned the entire celestial sky in infrared light about 1.5 times. It captured more than 2.7 million images of objects in space, ranging from faraway galaxies to asteroids and comets close to Earth.
When combined with WISE observations, NEOWISE data will aid in the discovery of the closest dim stars, called brown dwarfs. These observations have the potential to reveal a brown dwarf even closer to us than our closest known star, Proxima Centauri, if such an object does exist. Likewise, if there is a hidden gas-giant planet in the outer reaches of our solar system, data from WISE and NEOWISE could detect it.
The first batch of observations from the WISE mission will be available to the public and astronomical community in April.

NASA will have a Kepler Telescope news briefing Feb 2 to discuss over 1000 possible new exoplanets
- NASA will host a news briefing at 1 p.m. EST, Wednesday, Feb. 2, to announce the Kepler mission's latest findings about planets outside our solar system.
NASA released new data Wednesday from its Kepler telescope on more than 1,000 possible new planets outside our solar system — more than doubling the count of what astronomers call exoplanets. They haven't been confirmed as planets yet, but some astronomers estimate that 90 per cent of what Kepler has found will eventually be verified.
The news conference will follow the scheduled release of Kepler mission science data on Feb. 1. The data release will update the number of planet candidates and is based on observations conducted between May 2 and Sept. 17, 2009.

Development of Novel Transistor with Combined Logic and Memory Functions with Power Consumption Reduced to One-Millionth that of Conventional Devices
The University of Tokyo, succeeded in the development of a novel transistor, the “atom transistor,” which performs both logic and memory functions while reducing power consumption by one million times that of the conventional devices. Logic elements which are capable of retaining their state (i.e., memory) will be indispensible for the development of instant-on personal computers (PC) and other electronic equipment. The development in this work is expected to accelerate the realization of these devices.
Principles of logic element operation and memory element operation.
(a) When a positive voltage is applied to the gate electrode, metal atoms are supplied to the insulator from the gate electrode.
(b) When the concentration of metal atoms in the vicinity of the source/drain electrodes exceeds a critical value, the insulator changes to a conductive state.
(c) When an even higher voltage is applied, the metal atoms form a cluster.
(d) It is necessary to apply a negative voltage in order to dissolve the cluster.

Kazatomprom will boost uranium production to 19600 tons in 2011 and Areva delays Namibian mine Trekkopje
1. Kazakhstan plans to boost uranium output by 10 percent to 19,600 metric tons this year, said Vladimir Shkolnik, chief executive officer of the state nuclear company, Kazatomprom. The Central Asian nation produced 17,803 tons of uranium in 2010.
Carbon nanotubes for better solar cells
Angewandte Chemie International Edition - Flexible, Light-Weight, Ultrastrong, and Semiconductive Carbon Nanotube Fibers for a Highly Efficient Solar Cell
Tubes for sunlight: Solar cells with high short-circuit photocurrent, incident monochromatic photon-to-electron conversion efficiency, and power conversion efficiency have been made from flexible, light-weight, ultrastrong, and semiconductive nanotube fibers (see picture above). The alignment of the nanotubes in the fiber is crucial for the excellent charge separation and charge transport properties observed.
Chinese researchers fabricated fibers – with tunable uniform diameters ranging from micrometers to millimeters – that could be spun with lengths of tens of meters or even longer. High-resolution transmission electron microscopy indicates a multiwalled structure for the building nanotubes with diameter of approximately 8.5 nm in the fiber. Their nanotube fiber demonstrates much higher values in both specific strength and specific stiffness than current engineering fibers. The specific strength of a nanotube fiber is 2.9 times that of T1000, the strongest commercial fiber, and the specific stiffness is 3.9 times that of M70J, the stiffest commercial fiber.

Status of Jordan, Yemen and other countries facing public demonstrations
NY Times reports that the King of Jordan has dismissed his cabinet
Changing cabinets is not new for King Abdullah. In his 12 years on the throne, he has done so eight times. But this was the first time that he had done so in reaction to public pressure, seeking to undermine a growing protest movement across a broad spectrum of society and to pre-empt further unrest. It came after four weeks of unusual public demonstrations.
Calcite cloaks a pink piece of paper
A piece of pink paper vanishes under a new invisibility cloak developed by MIT researchers.
Science news has a picture of a calcite cloak covering a pink piece of paper.
In principle, Barbastathis says, the same method could be used in real-life situations to conceal an object from view — and the only limitation on the size of the hidden object is the size of the calcite crystal that’s available. The team paid about $1,000 for the small crystal it used, he says, but much larger ones could be used to conceal much larger objects. (The largest known natural crystal of calcite measures 7 by 7 meters, or more than 21 feet across).
Synthetic calcite crystals could be made even larger.

Per capita GDP PPP of $10,000 to 15000 (2000 dollars) seems to correlate with freedom and democracy
There is a collection of statistics which show the correlation between per capita GDP PPP and freedom and other good things in society Correlations do not show causal links but it is likely that the causation works both ways: higher GPD per capita means better education (because of more investment in education) and better education means higher GDP.
World's largest steel maker will be commercially launching stronger nanostructured steel in 2 to 3 years
The world's largest steel maker, ArcelorMital, has a new nanostructured steel which is not inherently lighter, but it's so strong that automakers can use thinner gauges and that's where part of the weight savings comes from. Another part of the weight savings comes from not having to use additional brackets, gussets or panels to strengthen the structure.

Media seems to think Mubarak will fade away quietly - confirmed
In 2006 cables from wikileaks, Oman Soliman a U.S. diplomatic cable described Suleiman as “formidable” and says he is Mubarak’s “consigliere” on foreign policy. Mubarak made his consigliere number two in his regime and told his consigliere to open talks (make offers to the opposition).
So now -
So at least some of offers (as per Godfather analogy- 'offer he can't refuse') have been refused.
UPDATE- Mubarak has announced that he will leave over the next few months
The drama continues:
Demonstrators what Mubarak to step down immediately and for a national unity caretaker government to fill in. They feel that this is a trick and a stalling tactic and that the current regime will fix the election as they have past elections
So now -
Mubarak’s Top Spy Rejected by Cairo Streets as Masses March.
UPDATE- Mubarak has announced that he will leave over the next few months
He said that over the next few months, "the remaining of my current reign, I will work very hard to carry out all the necessary measures to transfer power."

Bio-nano-chip in human trials to spot cardiac disease, cancer, drug abuse

To obtain a saliva sample for the Nano-Bio-Chip, health care providers swab a patient's gums with a cotton-tipped stick. The saliva is transferred to the disposable diagnostic microchip. The microchip is then inserted into an analyzer and within a few minutes the saliva sample is checked and results delivered. The nano-bio-chip that can diagnose a heart attack in 15 minutes using saliva. He's already developed a nano-bio-chip quick test for HIV.
New microchip technology from Rice University is expected to advance the art of diagnosis. Cardiac disease is the focus of one of six ongoing major clinical trials of Rice's programmable bio-nano-chips (PBNCs).
Previous pilot studies showed that ice's diagnostic nano-bio-chip was found to be 97 percent "sensitive" and 93 percent specific in detecting which patients had malignant or premalignant lesions, results that compared well with traditional tests.
Rice University scientists model tiny rotors, key to future nanomachines
Kolomeisky and Rice graduate student Alexey Akimov have taken a large step toward defining the behavior of these molecular whirligigs with a new paper in the American Chemical Society's Journal of Physical Chemistry C. Through molecular dynamics simulations, they defined the ground rules for the rotor motion of molecules attached to a gold surface.

The Total Universe flat and is at least 251 times larger than the visible universe
Arxiv - Applications of Bayesian model averaging to the curvature and size of the Universe
Bayesian model averaging is a procedure to obtain parameter constraints that account for the uncertainty about the correct cosmological model. We use recent cosmological observations and Bayesian model averaging to derive tight limits on the curvature parameter, as well as robust lower bounds on the curvature radius of the Universe and its minimum size, while allowing for the possibility of an evolving dark energy component. Because flat models are favoured by Bayesian model selection, we find that model-averaged constraints on the curvature and size of the Universe can be considerably stronger than non model-averaged ones. For the most conservative prior choice (based on inflationary considerations), our procedure improves on non model-averaged constraints on the curvature by a factor of ~ 2. The curvature scale of the Universe is conservatively constrained to be Radius of curvature greater than 42 Gigaparsecs (99%), corresponding to a lower limit to the number of Hubble spheres in the Universe NU (number of Universe volumes) over 251 (99%).
Kazakhstan doubles 2008 uranium production and Namibia Uranium expansion in progress
1. Kazakhstan's annual uranium production has doubled since 2008, according to preliminary uranium production results released by national atomic company Kazatomprom. The 17,803 tU produced by Kazakhstan in 2010 was nearly 30% up on the 14,020 tU produced in 2009 and double the amount produced in 2008.
Wall Street Journal lays out the Mubarak Strategy
Hundreds of thousands of people have flooded into central Cairo, where protesters have called for a "million-strong" march to press their demand that Egyptian President Hosni Mubarak cede power.
Most of the WSJ article at luxlibertas - Egypt's leader has gambled that he can ride out the protests and hold on. It's a pretty good gamble.
Egypt's newly appointed vice president said Mr. Mubarak has asked him to begin immediate discussions with all "political forces" on constitutional and legislative reforms. Omar Suleiman, a longtime intelligence (head spy) chief and confidant of Mr. Mubarak, did not say what the changes will entail or which groups the government will contact.
Most of the WSJ article at luxlibertas - Egypt's leader has gambled that he can ride out the protests and hold on. It's a pretty good gamble.
What unites the protesters is anger. But anger is an emotion, not a strategy, much less a political agenda. What, really, does "Down With Mubarak" offer the average Egyptian?
If the Brotherhood has its way, Egypt will become a Sunni theocracy modeled on Iran. If the democracy activists have theirs, it'll be a weak parliamentary system, incapable of exercising authority over the army and a cat's paw for a Brotherhood that knows its revolutionary history well enough to remember the name of Alexander Kerensky.
