Edward Zalta, the principal editor and senior research scholar at the Center for the Study of Language and Information:

"...while virtually anyone can contribute to Wikipedia and alter the text, 120 leading philosophers from around the world oversee contributions to the Stanford project, and its advisory board is the Stanford Department of Philosophy. No one can alter text without passing through several layers of approval...Our model is authoritative...Their model is one an academic isn't going to be attracted to. If you are a young academic, who might spend six months preparing a great article on Thomas Aquinas, you're not going to publish in a place where anyone can come along and change this."

MIT researchers create new self-assembling photovoltaic technology that repairs itself




http://web.mit.edu/newsoffice/2010/self-healing-solar.html

Molecules can turn sunlight into electricity & can be broken down and quickly reassembled

CAMBRIDGE, Mass. -- Plants are good at doing what scientists and engineers have been struggling to do for decades: converting sunlight into stored energy, and doing so reliably day after day, year after year. Now some MIT scientists have succeeded in mimicking a key aspect of that process.

One of the problems with harvesting sunlight is that the sun's rays can be highly destructive to many materials. Sunlight leads to a gradual degradation of many systems developed to harness it. But plants have adopted an interesting strategy to address this issue: They constantly break down their light-capturing molecules and reassemble them from scratch, so the basic structures that capture the sun's energy are, in effect, always brand new.

That process has now been imitated by Michael Strano, the Charles and Hilda Roddey Associate Professor of Chemical Engineering, and his team of graduate students and researchers. They have created a novel set of self-assembling molecules that can turn sunlight into electricity; the molecules can be repeatedly broken down and then reassembled quickly, just by adding or removing an additional solution. Their paper on the work was published on Sept. 5 in Nature Chemistry.

Strano says the idea first occurred to him when he was reading about plant biology. "I was really impressed by how plant cells have this extremely efficient repair mechanism," he says. In full summer sunlight, "a leaf on a tree is recycling its proteins about every 45 minutes, even though you might think of it as a static photocell."

One of Strano's long-term research goals has been to find ways to imitate principles found in nature using nanocomponents. In the case of the molecules used for photosynthesis in plants, the reactive form of oxygen produced by sunlight causes the proteins to fail in a very precise way. As Strano describes it, the oxygen "unsnaps a tether that keeps the protein together," but the same proteins are quickly reassembled to restart the process.

This action all takes place inside tiny capsules called chloroplasts that reside inside every plant cell — and which is where photosynthesis happens. The chloroplast is "an amazing machine," Strano says. "They are remarkable engines that consume carbon dioxide and use light to produce glucose," a chemical that provides energy for metabolism.

To imitate that process, Strano and his team, supported by grants from the MIT Energy Initiative and the Department of Energy, produced synthetic molecules called phospholipids that form discs; these discs provide structural support for other molecules that actually respond to light, in structures called reaction centers, which release electrons when struck by particles of light. The discs, carrying the reaction centers, are in a solution where they attach themselves spontaneously to carbon nanotubes — wire-like hollow tubes of carbon atoms that are a few billionths of a meter thick yet stronger than steel and capable of conducting electricity a thousand times better than copper. The nanotubes hold the phospholipid discs in a uniform alignment so that the reaction centers can all be exposed to sunlight at once, and they also act as wires to collect and channel the flow of electrons knocked loose by the reactive molecules.

The system Strano's team produced is made up of seven different compounds, including the carbon nanotubes, the phospholipids, and the proteins that make up the reaction centers, which under the right conditions spontaneously assemble themselves into a light-harvesting structure that produces an electric current. Strano says he believes this sets a record for the complexity of a self-assembling system. When a surfactant — similar in principle to the chemicals that BP has sprayed into the Gulf of Mexico to break apart oil — is added to the mix, the seven components all come apart and form a soupy solution. Then, when the researchers removed the surfactant by pushing the solution through a membrane, the compounds spontaneously assembled once again into a perfectly formed, rejuvenated photocell.

"We're basically imitating tricks that nature has discovered over millions of years" — in particular, "reversibility, the ability to break apart and reassemble," Strano says. The team, which included postdoctoral researcher Moon-Ho Ham and graduate student Ardemis Boghossian, came up with the system based on a theoretical analysis, but then decided to build a prototype cell to test it out. They ran the cell through repeated cycles of assembly and disassembly over a 14-hour period, with no loss of efficiency.

Strano says that in devising novel systems for generating electricity from light, researchers don't often study how the systems change over time. For conventional silicon-based photovoltaic cells, there is little degradation, but with many new systems being developed — either for lower cost, higher efficiency, flexibility or other improved characteristics — the degradation can be very significant. "Often people see, over 60 hours, the efficiency falling to 10 percent of what you initially saw," he says.

The individual reactions of these new molecular structures in converting sunlight are about 40 percent efficient, or about double the efficiency of today's best commercial solar cells. Theoretically, the efficiency of the structures could be close to 100 percent, he says. But in the initial work, the concentration of the structures in the solution was low, so the overall efficiency of the device — the amount of electricity produced for a given surface area — was very low. They are working now to find ways to greatly increase the concentration.

UK music calls for truce with technology

http://www.thinq.co.uk/2010/9/4/uk-music-calls-truce-technology

"The British music industry has called for a truce with the technology firms with whom it has till now fought a bitter battle over rights, royalties and file sharing. Feargal Sharkey, CEO of lobby group UK Music, told a conference in London this week that it was time for the music and technology industries to set aside their differences and strive instead toward a common goal: nothing less than the total global domination of British music.

Sharkey, a campaigner against people copying music on the internet and the technology they use, said it had become apparent that technology and creativity were inseparable.

"It's now time for ISPs and tech companies to sit down together and possibly for the first time have a broad adult conversation. Our future is now totally dependent, totally entwined, totally symbiotic," he told an audience of industry, government and media at the Westminster Forum this morning.

Sharkey was on rousing form. The former pop star called dramatically for the mobilization of British music and technology producers: "By 2020. We. Want. To rival. The United States. As the largest. Source of repertoire. And artistry. In. The. World."

"In short," he said, "We want to be number one."

The music industry scored a controversial success in April when the last government passed the Digital Economy Act, which would sanction the removal of people's internet connections if they were suspected of sharing copyrighted music online.

This had helped restore the equilibrium between creativity and technology that had, said Sharkey, been out of kilter. It was but a single "stepping stone" toward the music industry's goal of having people "remunerated for their talent time, effort and ability".

Nevertheless, he said, there should be a "reality check". Internet applications providers should think not about how many users they could get, but how sustainable were their business models.

"The internet has given everybody the opportunity to be a busker," he said. But with a nod to Napster, MySpace, We7, the Ipod, broadband, declared: "You can't democratize genius".

He appealed for "the ultimate solution", which was a music market place.

"It's now imperative that we all look forward and move towards what I hope will be a very bright and successful future, where the British music industry can in 10 years time become not only number one, but in doing so take British technology companies with us. My name's Feargal Sharkey. May God be with you."

Mexican drug cartels control parts of Arizona

http://www.washingtontimes.com/news/2010/aug/31/signs-in-arizona-warn-of-smuggler-dangers/

The federal government has posted signs along a major interstate highway in Arizona, more than 100 miles north of the U.S.-Mexico border, warning travelers the area is unsafe because of drug and alien smugglers, and a local sheriff says Mexican drug cartels now control some parts of the state.

The signs were posted by the Bureau of Land Management (BLM) along a 60-mile stretch of Interstate 8 between Casa Grande and Gila Bend, a major east-west corridor linking Tucson and Phoenix with San Diego.

They warn travelers that they are entering an "active drug and human smuggling area" and they may encounter "armed criminals and smuggling vehicles traveling at high rates of speed." Beginning less than 50 miles south of Phoenix, the signs encourage travelers to "use public lands north of Interstate 8" and to call 911 if they "see suspicious activity."

Pinal County Sheriff Paul Babeu, whose county lies at the center of major drug and alien smuggling routes to Phoenix and cities east and west, attests to the violence. He said his deputies are outmanned and outgunned by drug traffickers in the rough-hewn desert stretches of his own county.

"Mexican drug cartels literally do control parts of Arizona," he said. "They literally have scouts on the high points in the mountains and in the hills and they literally control movement. They have radios, they have optics, they have night-vision goggles as good as anything law enforcement has.

"This is going on here in Arizona," he said. "This is 70 to 80 miles from the border - 30 miles from the fifth-largest city in the United States."

He said he asked the Obama administration for 3,000 National Guard soldiers to patrol the border, but what he got were 15 signs.

Arizona Gov. Jan Brewer condemned what she called the federal government's "continued failure to secure our international border," saying the lack of security has resulted in important natural recreational areas in her state being declared too dangerous to visit.

In a recent campaign video posted to YouTube, Mrs. Brewer - standing in front of one of the BLM signs - attacked the administration over the signs, calling them "an outrage" and telling President Obama to "Do your job. Secure our borders."

BLM spokesman Dennis Godfrey in Arizona said agency officials were surprised by the reaction the signs generated when they were put up this summer.

"We were perhaps naive in setting the signs up," he said. "The intention of the signs was to make the public aware that there is potential illegal activity here. But it was interpreted in a different light, and that was not the intent at all."

He said there should be "no sense that we have ceded the land," adding that no BLM lands in Arizona are closed to the public.

"I kind of liken it to if I were visiting a city I were not familiar with and asked a policeman if it were safe to go in a particular area," Mr. Godfrey said.

Rising violence along the border has coincided with a crackdown in Mexico on warring drug gangs, who are seeking control of smuggling routes into the United States.

Mexican President Felipe Calderon has waged a bloody campaign against powerful cartels, yesterday announcing the arrest of Texas-born Edgar "La Barbie" Valdez - a powerful cartel leader captured outside of Mexico City on Monday evening.

More than 28,000 people have died since Mr. Calderon launched his crackdown in late 2006, and the bloodshed shows no sign of ending. Law enforcement authorities have been warning for more than two years that the dramatic rise in border violence eventually would spread into the U.S.

T.J. Bonner, president of the National Border Patrol Council, which represents all 17,500 of the Border Patrol's front-line agents, said areas well north of the border are so overrun by armed criminals that U.S. citizens are being warned to keep out of those locations.

"The federal government's lack of will to secure our borders is painfully evident when signs are posted well north of the border warning citizens that armed and dangerous criminals are roaming through those areas with impunity," he said. "Instead of taking the steps necessary to secure our borders, politicians are attempting to convince the public that our borders are more secure now than ever before.

"Fortunately, some responsible civil servants are candidly warning the public about the dangers that exist not just along the border but, in some cases, well beyond," he said. "This situation should alarm all sensible people, and should spur endless demands that our legislators take whatever actions are necessary to restore law and order to these areas."

Rep. Ted Poe, Texas Republican and a member of the House Judiciary and Foreign Affairs committees, said the federal government's new border security plan apparently is to "erect some signs telling you it's not safe to travel in our own country."

"If you are planning on loading up the station wagon and taking the kids to Disneyland, the federal government doesn't advise going through Arizona - it's too dangerous and they can't protect you," said Mr. Poe. "These signs say to American citizens, the federal government has ceded this area to the drug cartels. Don't come here; we can't protect you."

Rep. Lamar Smith of Texas, the ranking Republican on the House Judiciary Committee and a member of the House Committee on Homeland Security, called the signs "an insult to the citizens of border states."

"American citizens should not have to be fearful for their lives on U.S. soil," he said. "If the federal government would do its job of enforcing immigration laws, we could better secure the border and better protect the citizens of border states."

Michael W. Cutler, a retired 31-year U.S. Immigration and Naturalization Service (INS) senior criminal investigator and intelligence specialist, said the BLM warning signs suggest the U.S. government is "ceding American territory to armed criminals and smugglers."

Meanwhile, he said, politicians in Washington, D.C., including Homeland Security Secretary Janet Napolitano, continue to claim the border is now more secure than ever and, as a result, it is time for comprehensive immigration reform.

"How much more land will our nation cede to drug dealers and terrorists? At what point will the administration understand its obligations to really secure our nation's borders and create an immigration system that has real integrity?" Mr. Cutler said.

"At the rate we are going, the 'Red, White and Blue' of the American flag will be replaced with a flag that is simply white - the flag of surrender."

Ms. Napolitano said this week that U.S. Customs and Border Protection (CBP) would begin flying a Predator B drone out of Corpus Christi, Texas, on Wednesday, extending the reach of the agency's unmanned surveillance aircraft across the length of the 1,956-mile border with Mexico.

Last month, Mr. Obama signed a $600 million bill to beef up security along the southwestern border. The bill funds 1,000 more Border Patrol agents, as well as 250 CBP officers and two more unmanned aerial vehicles.

Two years ago, U.S. Immigration and Customs Enforcement (ICE), the investigative arm of Homeland Security, said in a report that border gangs were becoming increasingly ruthless and had begun targeting not only rivals, but federal, state and local police. ICE said the violence had risen dramatically as part of "an unprecedented surge."

The Justice Department's National Drug Intelligence Center, in its 2010 drug threat assessment report, called the cartels "the single greatest drug trafficking threat to the United States." It said Mexican gangs had established operations in every area of the United States and were expanding into rural and suburban areas. It said assaults against U.S. law enforcement officers along the southwestern border were on the increase - up 46 percent against Border Patrol agents alone.

At the same time, the Justice Department brought a lawsuit to stop a new immigration enforcement law in Arizona, saying it violated the Constitution by trying to supersede federal law and by impairing illegal immigrants' right to travel and conduct interstate commerce.

Mr. Cutler said it was "outrageous" for the BLM to direct travelers to dial 911 to report suspicious activities since the calls do not go to the federal government but to state and local police. He said the signs are telling Americans to call state and local law enforcement authorities to deal with border lawlessness while at the same time telling Arizona that only the federal government can write and enforce immigration laws.

"You can't make this stuff up," he said.

Mr. Godfrey said that just because the signs direct travelers who witness illegal activity to call 911, "that does not mean that only a local agency will respond."

"The idea is that people will get help as quickly as they can," he said.

Sheriff Babeu has dealt firsthand with the rising violence in his county since his 2008 election. One of his deputies, Louie Puroll, was shot and critically wounded in April after he spotted five men he suspected of transporting drugs along a remote span of desert near Interstate 8 and Arizona 84.

He said his experience makes him see the issue differently from the administration in Washington.

"The president is only looking at this from a political perspective," he said. "Everything is not fine. Everything is not OK."

Who Is The Man Behind The Ground Zero Mosque?

http://newyork.cbslocal.com/2010/08/30/who-is-the-man-behind-the-ground-zero-mosque/

Developer Of Community Center Has Lengthy Record, With Numerous Arrests Dating Back To 1990

NEW YORK (CBS 2) — As the Ground Zero mosque controversy continues to simmer, questions continue about the background of the man who wants to build the $100 million Islamic cultural and religious center.

Mosque developer Sharif El-Gamal has often been reluctant to answer questions.

After he won the right to tear down the 152-year-old building blocks from the site of the 9/11 attacks, El-Gamal got defensive when asked about the mosque by CBS 2′s Marcia Kramer.

“It’s a community center, if you call it a community center, we would talk,” El-Gamal said.

Kramer reports the developer’s reluctance to talk may have been related to his prior run-ins with the law.

His most recent arrest was in 2005 for assault on a man he met while working as a waiter at Serafina Restaurant, who sublet an apartment from his brother. He reportedly punched the man, breaking his nose and cheekbone and spit on him.

El-Gamal first said he didn’t hit the man, but arrest documents obtained by CBS 2 showed he later conceded “his face could have run into my hand.”

Records showed El-Gamal also had trouble coming up with the $15,000 settlement reached in 2008, and had to pay interest . El-Gamal also has a number of other arrests on his record:

-In 1990, he was arrested in Nassau County and pled guilty to disorderly conduct.

-In 1992, he pled guilty in Nassau to DWI and paid a $350 fine.

-In 1993, he pled guilty in Nassau to attempted petit larceny and paid a $100 fine.

-In 1994, arrested for disorderly conduct in Manhattan.

-In 1998, there was another Manhattan disorderly conduct arrest.

-In 1999, yet another Manhattan disorderly conduct arrest.

A potential problem for the mosque developer is a deposition he gave in the assault case in October 2007. When asked if he was ever convicted or pled guilty to a crime, El-Gamal replied “no.”

Lately, he has been trying to resurrect his image, sitting down for a lengthy 60 Minutes interview with Scott Pelley.

When Pelley asked if it occurred to him that putting a project so close to Ground Zero would heighten tensions, El-Gamal replied “not at all.”

“I did not hold myself or my faith accountable for the tragedy,” El-Gamal said.

El-Gamal also owes over $227,000 in unpaid real estate taxes and a spokesman for the Department of Finance said interest will be added for each and every day its unpaid.

Another question surrounding the debate is whether the Muslim cleric of the mosque — Imam Feisal Abdul Rauf — knew about El-Gamal’s criminal background and unpaid taxes before partnering with him.

El-Gamal refused repeated requests from CBS 2 Monday to comment on the story.

Ron Paul questions whether there's gold at Fort Knox, NY Fed

http://thehill.com/blogs/blog-briefing-room/news/116341-ron-paul-plans-bill-to-audit-us-gold-reserves

By Michael O'Brien - 08/30/10 10:21 AM ET

Rep. Ron Paul (R-Texas) said he plans to introduce legislation next year to force an audit of U.S. holdings of gold.

Paul, a longtime critic of the Federal Reserve and U.S. monetary policy, said he believes it's "a possibility" that there might not actually be any gold in the vaults of Fort Knox or the New York Federal Reserve bank.

The libertarian lawmaker told Kitco News, a website tracking news about precious metals, that an audit was necessary to determine how much the U.S. maintains in gold reserves in case the government were to use gold to back the dollar.

“If there was no question about the gold being there, you think they would be anxious to prove gold is there,” he said.

“Our Federal Reserve admits to nothing, and they should prove all the gold is there. There is a reason to be suspicious and even if you are not suspicious why wouldn’t you have an audit?

“I think it is a possibility," Paul said when asked if there was truth to rumors that there was actually no gold at Ft. Knox or the New York Fed.

Paul had been one of the Republicans to spearhead a broader audit of the Fed as part of the Wall Street reform bill passed through Congress this year. The provision, which was weakened somewhat in the final version, found Paul joining with a number of Democrats to require the Fed to open its books and outline its assets and liabilities.

The gold reserves, which Paul's new bill would audit, are generally seen as a guarantee on a nation's currency, but the U.S. moved the dollar away from being tied to the price of gold in 1972.

Paul stopped short of calling for the reinstitution of the gold standard and instead called for the government to allow the use of hard currency — gold and silver tender — alongside the use of the dollar.

"If people get tired of using the paper standard they can deal in gold or silver,” he said.
