What if, instead of waiting days or weeks for a cast to be produced and prosthetic dental implants, false teeth and replacement crowns to be made, your dentist could quickly scan your jaw and "print" your new teeth using a rapid prototyping machine known as a 3D printer?

Researchers in Iran explain how medical imaging coupled with computer-aided design could be used to create a perfect-fit blueprint for prosthetic dentistry, whether to replace diseased or broken teeth and jaw bone. The blueprint can then be fed into a so-called 3D printer to build up an exact replica using a biocompatible composite material. Such technology has been used in medical prosthetics before, but this is an early step into prosthetic dentistry using rapid prototyping.

Writing in the International Journal of Rapid Manufacturing, mechanical engineer Hossein Kheirollahi of the Imam Hossein University and colleague Farid Abbaszadeh of the Islamic Azad University, in Tehran, Iran, explain how current technology used to convert an MRI or CT scan into a prosthetic component requires milling technology. This carves out the appropriate solid shape from a block of polymer but has several disadvantages, uppermost being that it is very difficult to carve out a complex shape, such as a tooth. By contrast, rapid prototyping uses a 3D image held in a computer to control a laser that then "cures" powdered or liquid polymer. Almost any solid, porous, or complicated shape can be produced by this 3D-printing technology.

The Iranian team has now demonstrated how rapid prototyping can be used to fabricate dental objects such as implants and crowns quickly and easily even where features such as overhangs, sharp corners and undercuts are required. The team points out that the most appropriate medical imaging technology, CBCT (cone-beam computed tomography), which is lower cost and exposes the patient to a lower dose of ionizing radiation is best suited to the generation of the computer design for creating such dental objects ready for printing.

TRANSCRIPT

Citizens of the United States, We are Anonymous.

This is an urgent emergency alert to all people of the United States. The day we've all been waiting for has unfortunately arrived. The United States is censoring the internet. Our blatant response is that we will not sit while our rights are taken away by the government we trusted them to preserve. This is not a call to arms, but a call to recognition and action!

The United States government has mastered this corrupt way of giving us a false sense of freedom. We think we are free and can do what we want, but in reality we are very limited and restricted as to what we can do, how we can think, and even how our education is obtained. We have been so distracted by this mirage of freedom, that we have just become what we were trying to escape from.

For too long, we have been idle as our brothers and sisters were arrested. During this time, the government has been scheming, plotting ways to increase censorship through means of I S P block aides, D N S blockings, search engine censorship, website censorship, and a variety of other methods that directly oppose the values and ideas of both Anonymous as well as the founding fathers of this country, who believed in free speech and press!

The United States has often been used as an example of the ideal free country. When the one nation that is known for its freedom and rights start to abuse its own people, this is when you must fight back, because others are soon to follow. Do not think that just because you are not a United States citizen, that this does not apply to you. You cannot wait for your country to decide to do the same. You must stop it before it grows, before it becomes acceptable. You must destroy its foundation before it becomes too powerful.

Has the U.S. government not learned from the past? Has it not seen the 2011 revolutions? Has it not seen that we oppose this wherever we find it and that we will continue to oppose it? Obviously the United States Government thinks they are exempt. This is not only an Anonymous collective call to action. What will a Distributed Denial of Service attack do? What's a website de face ment against the corrupted powers of the government? No. This is a call for a worldwide internet and physical protest against the powers that be. Spread this message everywhere. We will not stand for this! Tell your parents, your neighbors, your fellow workers, your school teachers, and anyone else you come in contact with. This affects anyone that desires the freedom to browse anonymously, speak freely without fear of retribution, or protest without fear of arrest.

Go to every I R C network, every social network, every online community, and tell them of the atrocity that is about to be committed. If protest is not enough, the United States government shall see that we are truly legion and we shall come together as one force opposing this attempt to censor the internet once again, and in the process discourage any other government from continuing or trying.

We are Anonymous.
We are Legion.
We do not forgive censorship.
We do not forget the denial of our free rights as human beings.
To the United States government, you should've expected us.

 

The world-record magnet is operating at 25 tesla, easily besting the 17.5 tesla French record set in 1991 for this type of magnet. ("Tesla," named for early 20th-century inventor and engineer Nikola Tesla, is a measurement of the strength of a magnetic field.) In addition to being 43 percent more powerful than the previous world best, the new magnet also has 1,500 times as much space at its center, allowing room for more flexible, varied experiments.

To offer some perspective on the strength of the new magnet, consider this: Twenty-five tesla is equal to a whopping 500,000 times the Earth's magnetic field. Imagine that much power focused on a very small space and you have some idea what the split magnet is capable of — and why both engineers and scientists at the magnet lab are so excited.

"The Mag Lab has developed numerous world-record magnets; however, the split magnet makes the largest single step forward in technology over the past 20 years," said Mark Bird, director of the laboratory's Magnet Science and Technology division.

For decades, scientists have used high magnetic fields to probe the unusual properties of materials under extreme conditions of heat and pressure. There are unique benefits that arise at especially high magnetic fields — certain atoms or molecules become more easily observable, for example, or exhibit properties that are difficult to observe under less extreme conditions. The powerful new split magnet system holds promise for even more breakthroughs at the very edge of human knowledge.

The new magnet was funded by the National Science Foundation and represents years of intense collaboration between the lab's engineering and research teams, headed by scholar/scientist Jack Toth of the Magnet Science and Technology staff.

The magnet's design required Toth's team to rethink the structural limits of resistive magnets — that is, those in which the magnetic field is produced by the flow of electric current. The project required that the engineers invent, patent and find sometimes-elusive builders for the technology that could carry their idea through. The result of their work, the new split magnet, features four large elliptical ports that provide scientists with direct, horizontal access to the magnet's central experimental space, or bore, while still maintaining a high magnetic field.

High-powered research magnets are created by packing together dense, high-performance copper alloys and running an electrical current through them. All of the magnet's forces are focused on the center of the magnet coil — right where Toth and his team engineered the four ports. Building a magnet system with ports strong enough to withstand such strong magnetic fields and such a heavy power load was once considered impossible.

To accomplish the impossible, Toth's team cut large holes in the mid-plane of the magnet to provide user access to the bore but maintain a high magnetic field. All of this had to be done while supporting 500 tons of pressure pulling the two halves of the magnet together and, at the same time, allowing 160,000 amps of electrical current and 3,500 gallons of water per minute to flow through the mid-plane. (The water is needed to keep the magnet from overheating.)

While the technological breakthroughs enabling the magnet's construction are important, the multidisciplinary research possibilities are even more exciting. Optics researchers in chemistry, physics and biology are poised to conduct research using the split magnet, while others are optimistic about the potential for breakthroughs in nanoscience and semiconductor research.

The magnet's first user, a scientist from Kent State University, has already begun conducting experiments.

"Among other research possibilities," said Eric Palm, director of the magnet lab's Direct Current User Program, "the split magnet will allow optics researchers unprecedented access to their samples, improve the quality of their data, and enable new types of experiments."

Of all the energy-saving tips out there, probably the one we hear most often is to not leave lights on when we leave a room. It's good advice, yet cities around the world are not following it in one key way - their streetlights stay on all night long, even when no one is on the street. The Netherlands' Delft University of Technology is experimenting with a new streetlight system on its campus, however, in which motion sensor-equipped streetlights dim to 20 percent power when no people or moving vehicles are near them. The system is said to reduce energy consumption and CO2 emissions by up to 80 percent, plus it lowers maintenance costs and reduces light pollution.

Delft Management of Technology alumnus Chintan Shah designed the system, which can be added to any dimmable streetlight. The illumination comes from LED bulbs, which are triggered by motion sensors. As a person or car approaches, their movement is detected by the closest streetlight, and its output goes up to 100 percent. Because the lights are all wirelessly linked to one another, the surrounding lights also come on, and only go back down to 20 percent once the commuter has passed through. This essentially creates a "pool of light" that precedes and follows people wherever they go, so any thugs lurking in the area should be clearly visible well in advance.

The lights' wireless communications system also allows them to automatically notify a central control room when failures (such as burnt-out bulbs) occur. This should make maintenance much simpler, as crews will know exactly where to go, and when.

Some fine-tuning is still ongoing, in order to keep the lights from being activated by things like swaying branches or wandering cats. In the meantime, Shah has formed a spin-off company named Tvilight to market the Delft technology. He claims that municipalities utilizing the system should see it paying for itself within three to four years of use.

Storing the sun’s heat in chemical form — rather than converting it to electricity or storing the heat itself in a heavily insulated container — has significant advantages, since in principle the chemical material can be stored for long periods of time without losing any of its stored energy. The problem with that approach has been that until now the chemicals needed to perform this conversion and storage either degraded within a few cycles, or included the element ruthenium, which is rare and expensive.

 

Last year, MIT associate professor Jeffrey Grossman and four co-authors figured out exactly how fulvalene diruthenium — known to scientists as the best chemical for reversibly storing solar energy, since it did not degrade — was able to accomplish this feat. Grossman said at the time that better understanding this process could make it easier to search for other compounds, made of abundant and inexpensive materials, which could be used in the same way.

Now, he and postdoc Alexie Kolpak have succeeded in doing just that. A paper describing their new findings has just been published online in the journal Nano Letters, and will appear in print in a forthcoming issue.

The new material found by Grossman and Kolpak is made using carbon nanotubes, tiny tubular structures of pure carbon, in combination with a compound called azobenzene. The resulting molecules, produced using nanoscale templates to shape and constrain their physical structure, gain “new properties that aren’t available” in the separate materials, says Grossman, the Carl Richard Soderberg Associate Professor of Power Engineering.

Not only is this new chemical system less expensive than the earlier ruthenium-containing compound, but it also is vastly more efficient at storing energy in a given amount of space — about 10,000 times higher in volumetric energy density, Kolpak says — making its energy density comparable to lithium-ion batteries. By using nanofabrication methods, “you can control [the molecules’] interactions, increasing the amount of energy they can store and the length of time for which they can store it — and most importantly, you can control both independently,” she says.
Thermo-chemical storage of solar energy uses a molecule whose structure changes when exposed to sunlight, and can remain stable in that form indefinitely. Then, when nudged by a stimulus — a catalyst, a small temperature change, a flash of light — it can quickly snap back to its other form, releasing its stored energy in a burst of heat. Grossman describes it as creating a rechargeable heat battery with a long shelf life, like a conventional battery.

One of the great advantages of the new approach to harnessing solar energy, Grossman says, is that it simplifies the process by combining energy harvesting and storage into a single step. “You’ve got a material that both converts and stores energy,” he says. “It’s robust, it doesn’t degrade, and it’s cheap.” One limitation, however, is that while this process is useful for heating applications, to produce electricity would require another conversion step, using thermoelectric devices or producing steam to run a generator.
While the new work shows the energy-storage capability of a specific type of molecule — azobenzene-functionalized carbon nanotubes — Grossman says the way the material was designed involves “a general concept that can be applied to many new materials.” Many of these have already been synthesized by other researchers for different applications, and would simply need to have their properties fine-tuned for solar thermal storage.

The key to controlling solar thermal storage is an energy barrier separating the two stable states the molecule can adopt; the detailed understanding of that barrier was central to Grossman’s earlier research on fulvalene dirunthenium, accounting for its long-term stability. Too low a barrier, and the molecule would return too easily to its “uncharged” state, failing to store energy for long periods; if the barrier were too high, it would not be able to easily release its energy when needed. “The barrier has to be optimized,” Grossman says.

Already, the team is “very actively looking at a range of new materials,” he says. While they have already identified the one very promising material described in this paper, he says, “I see this as the tip of the iceberg. We’re pretty jazzed up about it.”

Yosuke Kanai, assistant professor of chemistry at the University of North Carolina at Chapel Hill, says “the idea of reversibly storing solar energy in chemical bonds is gaining a lot of attention these days. The novelty of this work is how these authors have shown that the energy density can be significantly increased by using carbon nanotubes as nanoscale templates. This innovative idea also opens up an interesting avenue for tailoring already-known photoactive molecules for solar thermal fuels and storage in general.”

Berlusconi, who failed to secure a majority in a crucial vote on Tuesday, stepped down as prime minister after parliament passed a package of measures demanded by European partners to restore market confidence in Italy's strained public finances.

Former European Commissioner Mario Monti is expected to be given the task of trying to form a new administration to face a widening financial crisis which has sent Italy's borrowing costs to unmanageable levels.

More than a thousand demonstrators waving banners mocking Berlusconi flocked to the president's residence at the Quirinale Palace as the motorcade carrying the billionaire media entrepreneur, who has been Italy's longest serving prime minister, entered.

The crowd grew so unruly that Berlusconi was forced to leave secretly via a side entrance and return to his private residence.

Cheers broke out when they heard that Berlusconi had resigned and the square broke out into a party atmosphere. People sang, danced and some broke open bottles of champagne.

An orchestra near the palace played the Hallelujah chorus from Handel's Messiah. "We are here to rejoice," one said.

Demonstrators chanting "resign, resign, resign" also gathered outside the prime minister's office and parliament, heckling ministers as they walked between the two buildings.

A small group of pro-Berlusconi demonstrators gathered outside his residence but were hugely outnumbered by opponents.

After the resignation, hundreds shouting "Jail, Jail, Jail,"

moved from the presidential palace to Berlusconi's residence to continue the noisy celebrations below his windows.

"This is something that deeply saddens me," the Italian news agency Ansa quoted Berlusconi as telling aides.

President Giorgio Napolitano will begin consultations with political leaders at 5:00 a.m. EST on Sunday morning. He was expected to ask Monti for form a government on Sunday night.

Italy, the euro zone's third largest economy, came close to disaster this week when yields on 10-year bonds soared over 7.6 percent, the kind of level which forced Ireland, Portugal and Greece to seek international bailouts.

Berlusconi, who failed to secure a majority in a vote on Tuesday, promised to resign once parliament passed the package of economic reforms demanded by European partners to restore confidence in Italy's battered public finances.

Monti, named by Napolitano as a Senator for Life on Wednesday, is expected to appoint a relatively small cabinet of technocrat specialists to steer Italy through the crisis.

With the next election not due until 2013, a technocrat government could have about 18 months to pass painful economic reforms but will need to secure the backing of a majority in parliament and could fall before then.

With a public debt of more than 120 percent of gross domestic product and more than a decade of anemic economic growth behind it, Italy is at the heart of the euro zone debt crisis and would be too big for the bloc to bail out.

Financial markets have backed a Monti government and as prospects of Berlusconi going became firmer last week, yields dropped below the critical 7 percent level, although they remain close.

"We don't yet have a new government in Italy and we have to wait, but I'm sure if Mario Monti will be appointed he will do whatever is necessary in order to restore the confidence of the financial markets in Italy," Alessandro Profumo, former head of Unicredit, Italy's largest bank, told Reuters.

SIGNS OF OPPOSITION MOUNT

Berlusconi, fighting an array of scandals and facing trials on charges ranging from tax fraud to paying for sex with an under-aged prostitute, had been under pressure to resign for weeks as the market crisis threatened to spin out of control.

International leaders including U.S. President Barack Obama, French President Nicolas Sarkozy and the head of the International Monetary Fund Christine Lagarde have expressed hopes a new government can be in place quickly.

Talks with Italian political parties are expected to begin on Sunday with hopes that a new government can be in place in time for the opening of financial markets on Monday.

However, even as preparations for a transition begin, signs of opposition have appeared, with Berlusconi's PDL party split between factions ready to accept a Monti government and others deeply opposed.

Berlusconi had a working lunch with Monti before the vote, suggesting the outgoing government will not try to block a quick handover, but the attitude of the center-right as a whole remains unclear.

The PDL's main coalition ally, the regional pro-devolution Northern League, has declared it will go into opposition, underlining the risk that the new government will lack the broad parliamentary support it will need to pass deep reforms.

"The convulsions in the center-right at the prospect of a government led by Mario Monti signal a danger: that a divided coalition may be tempted to unload its divisions on the country," the daily Corriere della Sera said.

The center-left Democratic party and smaller centrist parties have pledged support to Monti. Italy's main business and banking associations and some of the moderate trade unions have also called for a government of national unity.

The technology amplifies any anthrax DNA present in the sample and can reveal the presence of just 40 microscopic cells of the deadly bacteria Bacillus anthracis.

B. anthracis, commonly known as anthrax, is a potentially lethal microbe that might be used intentionally to infect victims through contamination of food and water supplies, aerosolized particles, or even dried powders, such as those used in bioterrorist attacks in the USA. Detection is crucial to preventing widespread fatalities in the event of an anthrax attack. However, the complexity of the microbe's biology have so far made it difficult to build a portable system that can be employed quickly in the field. That said, there are several systems available that use PCR to amplify a particular component of the genetic material present in anthrax and then to flag this amplified signal. These systems are fast and sensitive but do not integrate sample preparation and so are not as convenient as a single detector unit would be.

Writing in the International Journal of Biomedical Nanoscience and Nanotechnology this month, Nathaniel Cady of the College of Nanoscale Science and Engineering (CNSE) of the University at Albany and colleagues there and at Cornell University, New York, explain how they have constructed nanofabricated fluidic cartridges that can be used to carry out detection of anthrax. The device is a so-called "lab-on-a-chips" device, or more properly a 3D microfluidic network that contains nanofabricated pillar structures.

The device has fluidic inputs for adding sample and reagents, removing waste, for carrying out DNA purification, and critically an integrated chamber for amplifying only the target DNA in the sample using the polymerase chain reaction (PCR) system. The chip also contains a wave guide for the fluorescence-based identification of the amplified DNA and thus the target microbe. Importantly, the system works without manual intervention other than loading a droplet of sample into the detector.

"The average time required for DNA purification during these experiments was approximately 15 min, and when combined with real-time PCR analysis, this resulted in an average time to detection of 60 min," the team says. The system can detect as few as 40 B. anthracis cells. "Due to its small size and low power requirements, this system can be further developed as a truly portable, hand-held device," the researchers conclude.

You could never prosecute WikiLeaks without criminalizing all journalism in the United States. - Glenn Greenwald

This is a "WikiLeaks News Update", a news update of stories relating directly to WikiLeaks and also freedom of information, transparency, cybersecurity, and freedom of expression.

WikiLeaks News: Collateral Murder changes US interrogator's views, WL/Bradley #Manning Support

On Veteran's day, The Atlantic interviews Michael Patterson, a former U.S. army interrogator whose decision to leave the army and current participation in the Occupy Movement (Michael is staying at Occupy DC) were motivated by the video Collateral Murder, released by WikiLeaks on the 5th April 2010:

"... I ask him what was the switch for him and when. He explained that it was WikiLeaks. It was the footage of the Apache helicopter gunning down Iraqis released by WikiLeaks in April of 2010. Up to that point he had been interrogating Iraqis and using what he describes as psychological torture. He was 10 years old when the World Trade Center was hit. He wanted to fight terrorism in Iraq. He bought into the whole thing, he tells me. He had been looking forward to signing up ever since the 5th grade and then, suddenly, last November, he found himself watching a video of his fellow soldiers gunning down Iraqis on the street and it all changed for him.

The Apache video, to a civilian, makes war look like a video game, but to Patterson, it was the first time he saw Iraqis as real people. Random people, with children and families who care about them. He tried to get out of the military as a conscientious objector after that. He was told it wouldn't work because he's an atheist. "So I just smoked a bunch of pot and got kicked out," he says. He was officially discharged on June 7th of this year. He went back home to Alaska, where he read about Occupy Wall Street on Reddit.

He then went to D.C. to sleep in a tent a block away from the White House."

EFF and ACLU respond to Court ruling WikiLeaks' associates private twitter records are to be disclosed to the US government, as part of a Grand Jury investigation on WikiLeaks.
A statement released by EFF (Electronic Frontier Foundations), titled 'Privacy Loses in Twitter/Wikileaks Records Battle' reads:

'... Jonsdottir and others only found out about the government requests for information because Twitter took steps to notify them of the court order. EFF is urging other companies to follow Twitter's lead, stand with their customers, and promise to inform users when their data is sought by the government, as part of our Who Has Your Back? campaign.'

Both organizations represent Icelandic MP and former WikiLeaks volunteer Birgitta Jonsdottir in the case. Read ACLU's press release on this subject here.
In an interview to The Guardian, Birgitta declared the intention to take the case to the Council of Europe.

Vigil for Bradley Manning on his 24th Birthday

ImageSaturday, December 17 · 12:00am - 11:30pm
On the 17th of December - his 24th birthday - Bradley Manning will have been incarcerated for 571 days.

On this day stand in solidarity with Bradley Manning whose only crime was revealing the truth - congregate at the White House, your city hall or town square, or your nearest US Embassy or Consulate - peacefully and solemnly. [For more details, see Vigil for Bradley Manning on his 24th Birthday's facebook page.]
Other upcoming campaigns in support of Bradley Manning:

* Starting next Monday (November 14), a Call-in to The White House and Military to Demand UN Access to Bradley Manning will take place throughout the week. Additional information will be posted on the Bradley Manning Support Network website, bradleymanning.org.

* Bradley's 24th birthday will be on December 17th. This is the second birthday the alleged whistleblower will have spent detained in a military prison, without trial. Everyone is encouraged to gather support for Bradley Manning on this day and to send small gifts and birthday cards to the following address

Bradley Manning 89289

Fort Leavenworth, KS 6602


Julian Assange/WikiLeaks Support Campaigns

* November 17: Headed by Christine Assange, Julian Assange's mother, a protest against Julian's extradition and US government actions against WikiLeaks will occur in front of the Parliament House in Canberra on the occasion of US President Obama's visit to Australia. Please join.
Know more about this protest.

* Online Human Rights petition demanding Julian Assange be protected by the Australian Parliament from extradition to the United States.

Julian Assange has been under house arrest for 339 days without having been charged of a crime. (Visit Sweden vs. Assange for all information on this case.) Bradley Manning has spent 535 days detained without trial. A Fair Trials International campaign was launched to end pre-trial detention within the EU. Fair Trials International also advocate the reform of the European Arrest Warrant:

The EAW has removed many of the traditional safeguards in the extradition process. If a court in one country demands a person’s arrest and extradition, courts and police in other countries must act on it. In 2009, this fast track extradition system was used to extradite over 4,000 people across the EU (700 people from the UK alone).

Although it was intended to deliver justice, the current system is actually resulting in cases of serious injustice. Our own casework repeatedly demonstrates the human cost of EU extradition. Fair Trials International will continue to press for an EU extradition system which is both fair and effective. Through our Justice in Europe campaign, we are succeeding in making the case for reform.

And, the study found, pet owners were just as close to key people in their lives as to their animals, indicating no evidence that relationships with pets came at the expense of relationships with other people, or that people relied more on pets when their human social support was poorer.

Psychologists at Miami University and Saint Louis University conducted three experiments to examine the potential benefits of pet ownership among what they called everyday people. The results of the current study were reported in the Journal of Personality and Social Psychology, published online by APA.

“We observed evidence that pet owners fared better, both in terms of well-being outcomes and individual differences, than non-owners on several dimensions,” said lead researcher Allen R. McConnell, PhD, of Miami University in Ohio. “Specifically, pet owners had greater self-esteem, were more physically fit, tended to be less lonely, were more conscientious, were more extraverted, tended to be less fearful and tended to be less preoccupied than non-owners.”

Until now, most research into the benefits of pets has been correlational, meaning it looked at the relationship between two variables but didn’t show that one caused the other. For example, prior research showed that elderly Medicare patients with pets had fewer doctor visits than similar patients without pets, or that HIV-positive men with pets were less depressed than those without.

In this study, 217 people (79 percent women, mean age 31, mean annual family income $77,000) answered surveys aimed at determining whether pet owners in the group differed from people who didn’t have pets in the areas of well-being, personality type and attachment style. Several differences between the groups emerged, and in all cases, pet owners were happier, healthier and better adjusted than were non-owners.

A second experiment, involving 56 dog owners (91 percent of whom were women, with a mean age of 42 and average annual family income of $65,000), examined whether pet owners benefit more when their pet is perceived to fulfill their social needs better. This study found greater well-being among owners whose dogs increased their feelings of belonging, self-esteem and meaningful existence.

The last study, comprising 97 undergraduates with an average age of 19, found that pets can make people feel better after experiencing rejection. Subjects were asked to write about a time when they felt excluded. Then they were asked to write about their favorite pet, or to write about their favorite friend, or to draw a map of their campus. The researchers found that writing about pets was just as effective as writing about a friend when it came to staving off feelings of rejection.

“[T]he present work presents considerable evidence that pets benefit the lives of their owners, both psychologically and physically, by serving as an important source of social support,” the researchers wrote. “Whereas past work has focused primarily on pet owners facing significant health challenges … the present study establishes that there are many positive consequences for everyday people who own pets.”
