Iran Nuclear Talks Called 'Substantive'; Next Round Set For November

Iran and six world powers Wednesday hailed the latest round of negotiations on Tehran’s disputed nuclear program as “substantive and forward looking” and set an accelerated schedule of meetings to find whether they can strike the deal both sides want.

The discussions, begun at a moment of renewed hope for progress, were described as difficult and tense at times. Yet the Iranians and their negotiating partners were able to reach a rare agreement on a joint statement praising each side and signaling their commitment to a diplomatic solution to the standoff.

A senior U.S. official said that in years of diplomacy, the two sides had never had such “intense, detailed, straightforward, candid” talks. The Iranian government, which until the arrival of a new administration in August had been mostly hostile to world pressure against its nuclear program, praised the discussions in the state-controlled press.

Even so, the two sides provided few details of their talks, leaving it unclear whether Iran has come any closer to accepting immediate curbs to the program, which many countries fear is aimed at acquiring a nuclear weapons capability.

Plummeting Morale At Fukushima Daiichi As Nuclear Cleanup Takes Its Toll

Dressed in a hazardous materials suit, full-face mask and hard hat, Japan's prime minister, Shinzo Abe, left his audience in no doubt: "The future of Japan," he said, "rests on your shoulders. I am counting on you."

Abe's exhortation, delivered during a recent visit to the Fukushima Daiichi nuclear power plant, was only heard by a small group of men inside the plant's emergency control room. But it was directed at almost 6,000 more: the technicians and engineers, truck drivers and builders who, almost three years after the plant suffered a triple meltdown, remain on the frontline of the world's most dangerous industrial cleanup.


The hazards faced by the nearly 900 employees of Tokyo Electric Power [Tepco] and about 5,000 workers hired by a network of contractors and sub-contractors were underlined this month when six men were doused with contaminated water at a desalination facility.


Commenting on the leak, the head of Japan's nuclear regulator, Shunichi Tanaka, told reporters: "Mistakes are often linked to morale. People usually don't make silly, careless mistakes when they're motivated and working in a positive environment. The lack of it, I think, may be related to the recent problems."





Xenophobic Riots: Moscow Nervous after Violence Erupts

Moscow authorities are apprehensive following anti-immigrant riots in a southern suburb on Sunday night. And though neo-Nazis continue to stir xenophobic sentiments, it's clear that the Kremlin has done its own part to fuel these attitudes.


Far to the south lies the district of Biryulyovo, home to some 90,000 residents. Just one of the Russian capital's dozens of suburbs, it was relatively obscure until Sunday -- when xenophobic rioting made international headlines.  


The riots were sparked by the death of a young Biryulyovo resident, 25-year-old Yegor Sherbakov, who was allegedly stabbed by a "non-Russian" on his way home on Thursday night, according to his girlfriend. After the man allegedly harassed the couple around 2 a.m. there was a scuffle, and media reports say that the blade injured Sherbakov's heart. He died at the scene.

On Sunday afternoon, several thousand demonstrators gathered to demand action from city officials -- namely the arrest of the murderer and the deportation of the area's guest workers from central Asia and the Caucasus. A number of right-wing extremists from throughout the Moscow area were reportedly on hand after neo-Nazis put out the call on Internet forums the day before, and several hundred clashed with police for hours. Though officers from the feared OMON special unit were also present, the police failed to gain the upper hand.

On Kauai, Marathon GMO Hearing Ends With Strict Rules For Biotech

After a marathon hearing, the Kauai County Council passed a hotly debated bill on Wednesday that could lead to prison time or fines for employees of agricultural companies if they don’t divulge specifics about pesticide use, abide by strict setback rules for spraying chemicals or disclose when they grow genetically engineered crops.

The council voted 6 to 1 to make Bill 2491 into law. The lone vote against the bill came from Councilman Mel Rapozo, who said the measure unfairly targets biotech companies and sets the county up for lawsuits.


Supporters of the bill erupted in celebration of the vote, which came at 3:35 a.m., following the culmination of a hearing in which about 100 people argued for one side or the other. Cheers echoed inside the hearing room, while others could be heard on the front lawn where the public had remained around loudspeakers to listen to deliberations.

"To the seed companies, I want to make sure you understand that we have to envision the future for our island," said Council Chair Jay Furfaro minutes before the vote. "Your companies have your policies. But we need to envision Kauai in the future and this is a start for us."

Study Shows GM Corn Could Harm Aquatic Ecosystems

 A study by an Indiana University environmental science professor and several colleagues suggests a widely planted variety of genetically modified corn has the potential to harm aquatic ecosystems. The study is being published by the journal Proceedings of the National Academies of Sciences (PNAS).

  Researchers, including Todd V. Royer, an assistant professor in the IU School of Public and Environmental Affairs, established that pollen and other plant parts containing toxins from genetically modified Bt corn are washing into streams near cornfields.

  They also conducted laboratory trials that found consumption of Bt corn byproducts produced increased mortality and reduced growth in caddisflies, aquatic insects that are related to the pests targeted by the toxin in Bt corn. Caddisflies, Royer said, “are a food resource for higher organisms like fish and amphibians. And, if our goal is to have healthy, functioning ecosystems, we need to protect all the parts. Water resources are something we depend on greatly.”

  Other principal investigators for the study, titled “Toxins in transgenic crop byproducts may affect headwater stream ecosystems,” were Emma Rosi-Marshall of Loyola University Chicago, Jennifer Tank of Notre Dame, and Matt Whiles of Southern Illinois University.
It was funded by the National Science Foundation.





A Hard Look At 3 Myths About Genetically Modified Crops

In the pitched debate over genetically modified (GM) foods and crops, it can be hard to see where scientific evidence ends and dogma and speculation begin. In the nearly 20 years since they were first commercialized, GM crop technologies have seen dramatic uptake. Advocates say that they have increased agricultural production by more than US$98 billion and saved an estimated 473 million kilograms of pesticides from being sprayed. But critics question their environmental, social and economic impacts.

Researchers, farmers, activists and GM seed companies all stridently promote their views, but the scientific data are often inconclusive or contradictory. Complicated truths have long been obscured by the fierce rhetoric. “I find it frustrating that the debate has not moved on,” says Dominic Glover, an agricultural socioeconomist at Wageningen University and Research Center in the Netherlands. “The two sides speak different languages and have different opinions on what evidence and issues matter,” he says.


GM crops have bred superweeds: True
 Jay Holder, a farming consultant in Ashburn, Georgia, first noticed Palmer amaranth (Amaranthus palmeri) in a client’s transgenic cotton fields about five years ago. Palmer amaranth is a particular pain for farmers in the southeastern United States, where it outcompetes cotton for moisture, light and soil nutrients and can quickly take over fields.

Since the late 1990s, US farmers had widely adopted GM cotton engineered to tolerate the herbicide glyphosate, which is marketed as Roundup by Monsanto in St Louis, Missouri. The herbicide–crop combination worked spectacularly well — until it didn’t. In 2004, herbicide-resistant amaranth was found in one county in Georgia; by 2011, it had spread to 76. “It got to the point where some farmers were losing half their cotton fields to the weed,” says Holder.





Is There Really a Science-Based GMO Controversy?

  Discover magazine features a troubling cover story on the anti-agricultural biotechnology movement in its April [2013] issue (which you can read for free after registering at its site). Simply said, Discover gives unwarranted weight to anti-GM activists and in the process raises questions about the ability of even the most credible of science publications to avoid the perils of false balance when covering agricultural biotech.

As Keith Kloor pointed out in his sharply worded Collide-A-Scape blog (coincidentally hosted by the Discover website, where he is a respected blogger—points for Discover for encouraging this debate), the cover story focuses on the antics of GM protestors but ignores the recent push back from pro-science advocates in the United Kingdom, Europe and the United States.


The articles offer up a laundry list of familiar criticisms: biotech crops are untested; they hasten environmental degradation; they result in unstoppable superweeds; they pose health threats; they increase ‘dangerous’ pesticide usage; they could unleash unpredictable Frankenstein-like creatures into the world ecosystem; and so on.

These allegations—all of which are either demonstrably untrue or exaggerations of problems that are present in all of agriculture (including organic farming)—are the currency of such groups as the Environmental Working Group and the Union of Concerned Scientists, which make no pretense of their ideological rather than scientific opposition to GMOs.

Iran And Israel Go To Battle ... Over Denim

  [The issue] started last week when Israeli Prime Minister Benjamin Netanyahu told BBC's Persian TV that "if the Iranian people had their way, they'd be wearing bluejeans; they'd have Western music; they'd have free elections."


  Iranian elections may not be that free, and their music options may be somewhat limited. But young Iranians are proud of their freedom to choose their own pants, and often they choose jeans.


  Finally, in his interview, Netanyahu spoke about Neda Agha-Soltan, a young woman who was fatally shot at an anti-government protest in 2009. She was a key point in Netanyahu's argument about Iran's tyranny.

The moment she died in the street, Neda was wearing jeans.

Otis Redding Dies Before He Can Finish "(Sittin' on) The Dock of the Bay"

  For a guy renowned for his soulful energy on songs like "Respect" and "Satisfaction," it's almost ironic that Otis Redding's biggest claim to fame is "(Sittin' On) The Dock of the Bay," a gentle song about sitting around and doing jack shit. It's so mellow that for the last bit of the song, Redding just starts whistling. You might have thought that it was great symbolism, showcasing how at peace he is, just relaxing and watching ships instead of continuing with this "singing" bullshit.

  But the whistling wasn't supposed to be there -- it's meaningless filler. Redding's usual modus operandi was to ad lib at the end of his songs, and he wanted to do the same with "Dock." So his guitarist recorded 10 instrumental bars, allowing Otis to go on about love or sandwiches or whatever else was on his mind that day.

  So what was on his mind? Nothing, apparently. He stepped up to the mic and couldn't think of a damn thing to say. So, he started whistling instead. It sounded nice and all, but Redding really wanted actual words there. He was out of time, however, since he had TV and concerts to do. So, he figured he would just think up something and come back later to finish the track.

Sadly, he never got to -- two days later, he was killed in a plane crash.

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc).

  •  Air Flight 655 (9+ / 0-)

    WaPo: Flight 655’s fate in ’88 underlies Iran’s distrust of U.S.

    The story of Iran Air 655 begins, like so much of the U.S.-Iran struggle, with the 1979 Islamic revolution. When Iraq invaded Iran the following year, the United States supported Iraqi leader Saddam Hussein against the two countries' mutual Iranian enemy. The war dragged on for eight awful years, claiming perhaps a million lives.

    Toward the end of the war, on July 3, 1988, a U.S. Navy ship called the Vincennes was exchanging fire with small Iranian ships in the Persian Gulf. The U.S. Navy kept ships there, and still does, to protect oil trade routes. As the American and Iranian ships skirmished, Iran Air Flight 655 took off from nearby Bandar Abbas International Airport, bound for Dubai. The airport was used by both civilian and military aircraft. The Vincennes mistook the lumbering Airbus A300 civilian airliner for a much smaller and faster F-14 fighter jet, perhaps in the heat of battle or perhaps because the flight allegedly did not identify itself. It fired two surface-to-air missiles, killing all 290 passengers and crew members on board.

    The horrible incident brought Tehran closer to ending the war, but its effects have lingered much longer than that. "The shoot-down of Iran Air flight 655 was an accident, but that is not how it was seen in Tehran," former CIA analyst and current Brookings scholar Kenneth Pollack wrote in his 2004 history of U.S.-Iran enmity, The Persian Puzzle. "The Iranian government assumed that the attack had been purposeful. ... Tehran convinced itself that Washington was trying to signal that the United States had decided to openly enter the war on Iraq's side."

    That belief, along with Iraq's increased use of chemical weapons against Iran, led Tehran to accept a United Nations cease-fire two months later. But it also helped cement a view in Iran, still common among hard-liners in the government, that the United States is absolutely committed to the destruction of the Islamic Republic and will stop at almost nothing to accomplish this. It is, as Time's Michael Crowley points out in an important piece, one of several reasons that Iran has a hard time believing it can trust the United States to ever stop short of its complete destruction.

    The director of the U.S. National Security Agency and his deputy are expected to depart in the coming months, U.S. officials said on Wednesday, in a development that could give President Barack Obama a chance to reshape the eavesdropping agency.

    Army General Keith Alexander's eight-year tenure was rocked this year by revelations contained in documents leaked by former NSA contractor Edward Snowden about the agency's widespread scooping up of telephone, email and social-media data.

    Alexander has formalized plans to leave by next March or April, while his civilian deputy, John "Chris" Inglis, is due to retire by year's end, according to U.S. officials who spoke on condition of anonymity.

    That is the state to which the whole thing has devolved. The denizens of the monkeyhouse are bringing the world economy to the brink of chaos in order to fk their own staffs over on health insurance. Or at least that's what they say. In reality, what  this is about is a rump faction of one of our two major political parties that doesn't think we should have a federal government at all, that wants to roll back its functions to a state half-past the Articles of Confederation, and that is doing so while believing itself to be some unholy combination of the Founding Fathers and the X-Men. They have cast themselves in their own action adventure movie, and the rest of us serve pretty much the same function as New York City does in The Avengers. We're the set decoration that gets demolished as Our Heroes fight evil. These are pathetic, worthless children, playing dress-up, and smashing things because they like the sound of things breaking.

    By Tuesday afternoon, House Republican leaders were back with a new proposal to fund the government through Dec. 15, extend the debt ceiling into February and deprive not only lawmakers but all their staff members of employer assistance to buy their health care. By extending that provision to staff members, Republican leaders hoped to appeal to its far-right flank, but it angered more moderate Republicans and was not enough for the conservative hard core. Complicating the speaker's task, Heritage Action, the conservative Heritage Foundation's political arm, which wields great influence with the most conservative elements of the Republican Party, opposed the plan. "I think there's always hope there can be a final package I can vote on, but this is not the one," said Representative Ted Yoho, Republican of Florida, as he and two other Tea Party conservatives left the speaker's office.

    Ted Yoho.

    The power rests with Ted Yoho because the castrato Speaker Of The House, Boehner of Ohio, cares more about his job than he does about his country. The power rests with Ted Yoho because the American political system has tolerated carefully cultivated ignorance andcarefully tailored bigotry for far too long. Ted Yoho has been coming for years. Ted Yoho was made inevitable by the NCPAC campaigns of the late 1970's and by the elevation of Ronald Reagan to the presidency in 1980 and, subsequently, to an artificially exalted place in our history after he left office. The Republican party revelled in all the forces that are now tearing it apart. The Democratic party was criminally negligent and abdicated its profound responsibility to fight against those forces; indeed, it spent the better part of the 1980's and 1990's trying to surf the wave itself. The Democratic Leadership Council, and Blue Dog Democrats generally, bear a heavy burden of responsibility for failing to demonstrate to the American people in election after election how extreme the Republicans were becoming.


    The latest National Women’s Hall of Fame honoree says she's tired of bailing out the “irresponsible” GOP

    Throughout the ugly government shutdown battle, House Minority Leader Nancy Pelosi is the only national political leader who has seen her public approval-rating rise. In Gallup numbers released Wednesday, Speaker John Boehner’s approval dropped 14 points since April, while Pelosi’s rose 5 points in the same period.

    Pilloried by the GOP as uncompromising, Pelosi may seem to voters like someone tough enough to fight the crazy. And with 47 percent of Americans now saying they want Democrats to take back the House in 2014, she might be in line for Boehner’s job.

    Pelosi is certainly in line to have a better weekend than Boehner. On Saturday she’ll be inducted into the National Women’s Hall of Fame in Seneca Falls, N.Y., site of the historic 1848 American Women’s Rights Convention. It’s a diverse list of nine women, from midwife-activist Ina May Gaskin to feminist Kate Millett to Mother Mary Joseph Rodgers, the founder of the Catholic Maryknoll order of nuns.

    NYT: Big meteorite fragment found in Russian lake

    Russian officials on Wednesday retrieved the largest fragment so far of a meteor that exploded in February over the city of Chelyabinsk, but as divers and a mechanical winch lifted it from the bottom of a lake, the rock broke into three pieces, and then broke the scale — literally — when all together it weighed in at more than 1,250 pounds.

    Although a hole in the ice of Lake Chebarkul, southwest of Chelyabinsk, had made clear where the meteorite fragment landed, it took seven months of searching and a detailed sonar analysis to pinpoint its location, at a depth of about 40 feet and covered by about 8 feet of silt.


    As it was recovered, the meteorite fragment — which Russian scientists have estimated is more than 4.5 billion years old, or about as old as the solar system — was caught in a tangle of colorful ropes and cords, almost like an old piece of furniture tied to the top of a station wagon.

    “Come on, finish up,” an official shouted as a crowd of photographers and cameramen clustered around for a close look. “It will be available in the museum.”

    Seattle Times: The next giant quake: It’s coming and here’s how

    The earthquake that lashed the Pacific Northwest in 1700 ranks among the mightiest the Earth can yield. Scientists today call it a megaquake — a magnitude 9 monster that ripped the full length of the offshore fault where seafloor and continent collide, and unleashed a killer tsunami. Only a few seismic disasters in modern times have approached that level of fury.

    No one who saw the videos from the 2004 Indian Ocean megaquake and tsunami will ever forget the wall of water that pulverized cities and muscled through resorts as if they were made of cardboard. More than 200,000 people died. The force of the fault rupture made the Earth wobble on its axis.

     In March 2011, an offshore fault ripped loose off Japan. The magnitude 9 quake shoved the island of Honshu eight feet to the east and triggered a tsunami that reached the closest shores in 20 minutes. A nation whose leaders thought they were prepared for the worst watched in horror as waves poured over sea walls and swept nearly 20,000 people to their deaths. Nuclear reactors crippled by the flood melted down and spewed enough radiation to turn the surrounding countryside into a no man’s land.

    For Northwesterners, the images from Japan of doomed men and women running from the waves and tall buildings engulfed by water resonated in a visceral way. Even the world’s most earthquake-ready nation was no match for the kind of blow that had struck the Pacific Northwest more than three centuries ago — and which geologists now know will strike again someday. When it does, it will roil a human landscape that has undergone a tectonic shift of its own. The region called Cascadia is now home to more than 15 million people and several of North America’s most vibrant cities, businesses and ports.

    “The ‘Big One’ in the Pacific Northwest has the potential to be the most costly and destructive disaster in the history of the United States, both in terms of loss of life and economic damage,” said James Lee Witt, former director of the Federal Emergency Management Agency (FEMA). “The long-term economic impact could alter our entire economy.”

    This is the single most event that I fear will happen in my lifetime.
  •  capture light levels (6+ / 0-)


    Capturing light levels and turning them into an electric signal needed the talents of Johann Elster and Hans Geitel.

    These two students in Germany developed the the first practical photo electric cell that was able to measure light levels.

    Paul Nipkow, another German engineer and inventor produced a disc to scan images in 1876. Known as a "Nipkow Disc" it used a set of holes in a spiral formation to scan an image line by line.

    Friedrich Geitel


    Geitel and Elster published works on meteorology, nuclear physics, and the photoelectric effects.

    Geitel recognized the law of radioactive decay in 1899 and coined the term atomic energy. In 1893 he invented the photocell.

    Actually "photocell" can refer to lots of different things and you are talking about two of them! Let's agree that photocell means "thing that is sensitive to light".

    1) A light dependent resistor uses a chemical (typically a Cadmium compound like cadmium sulfide) that changes resistance when exposed to light. It doesn't convert light to current. To use one, you have to provide voltage and measure the change in current as the resistance changes (or you could provide a constant current and watch the voltage change; same thing).

    2) A silicon photocell (or solar cell) generates electricity from light. Photons (light particles) hit the silicon and cause electrons to flow out of the silicon (a little more complicated, but you asked for simple).

    3) A photo transistor uses light to turn on a transistor. Actually all "regular" transistors are light sensitive. A photo transistor is made to be sensitive and has a window in the can to let the light in.

    4) A photo diode is sort of like a photo transistor but used a diode.
    What Is a Photocell?


    A photocell is also known as a photoresister, as it decreases in resistance when exposed to light. It is used to locate and measure light and other radiations.


    Solid-state device that converts light into electrical energy by producing a voltage, as in a photovoltaic cell, or uses light to regulate the flow of current, as in a photoconductive cell: used in automatic control systems for doors, lighting, etc.


    A photocell is one of a wide range of sensors that will react based on the presence of light or electromagnetic energy. They are found in things like solar panels.

    Cramer’s Time Experiment Funded

    A physicist at the University of Washington, Cramer caught the attention of the press in recent months by discussing his hopes of testing the idea of quantum retrocausality. Here we’re in the domain of what Cramer calls the Transactional Interpretation, in which the processes of quantum mechanics involve waves traveling both forward and backward in time. His experiment, which may begin as early as next month, will test whether photons can communicate in reverse time.

    The notion, absurdly reduced, is this: Entangled photons seem to be able to affect each other no matter how widely separated in time or space, the so-called Einstein-Podolsky-Rosen paradox that illuminates the bizarre nature of quantum mechanics. Do a measurement on one and it has an immediate effect on the other. Cramer is testing whether this ‘spooky action at a distance’ is the result of communications that move backwards and forwards in time.


    If his experiment with splitting photons actually works, says University of Washington physicist John Cramer, the next step will be to test for quantum "retrocausality."

    That's science talk for saying he hopes to find evidence of a photon going backward in time.

    "It doesn't seem like it should work, but on the other hand, I can't see what would prevent it from working," Cramer said. "If it does work, you could receive the signal 50 microseconds before you send it."

    Cramer's form of time travel is not the teleportation characterized by Hollywood and science fiction. As time travel goes, Cramer thinks in baby steps. He's working on the possibility receiving a message milliseconds before it's sent.

    "I have to admit, this is pushing the envelope and often the envelop pushes back," says Cramer, a nuclear physicist who has worked on projects involving the Large Hadron Collider in Switzerland.

    In the basement of the campus physics building, Cramer is fiddling with laser beams to prove what Einstein called "spooky action at a distance". He's splitting photons through a series of synthetic crystals to demonstrate that quantum non-locality can be used to communicate.

    For those of us who never took high school physics, this is what he's trying to do in layman's terms: If you took a pair of photons created at the same time and altered one of those photons, in theory the other photon would be altered instantly -- even if it was separated by an entire galaxy.

    That would mean communication could travel faster than the speed of light over long distances. The ramifications of something Einstein didn't think was possible but theoretically could happen would be incredible. Physicists call it "nonlocal quantum communication."

      John G. Cramer is a professor of physics at the University of Washington in Seattle, the United States.

      When not teaching, he works with the STAR (Solenoidal Tracker At RHIC) detector at the new Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, and the particle accelerator at CERN in Geneva, Switzerland.

      He is currently engaged in experiments at the University of Washington to test retrocausality by using a version of the delayed choice quantum eraser without coincidence counting.

      This experiment, if successful, would imply that entanglement can be used to send a signal instantaneously between two distant locations (or a message backwards in time from the apparatus to itself).
