Pictures: Inside the World's Most Powerful Laser

Looking like a portal to a science fiction movie, preamplifiers line a corridor at the U.S. Lawrence Livermore National Laboratory's National Ignition Facility (NIF).

Preamplifiers work by increasing the energy of laser beams—up to ten billion times—before these beams reach the facility's target chamber.

The project's lasers are tackling "one of physics' grand challenges"—igniting hydrogen fusion fuel in the laboratory, according to the NIF website. Nuclear fusion—the merging of the nuclei of two atoms of, say, hydrogen—can result in a tremendous amount of excess energy. Nuclear fission, by contrast, involves the splitting of atoms.

This July, California-based NIF made history by combining 192 laser beams into a record-breaking laser shot that packed over 500 trillion watts of peak power-a thousand times more power than the entire United States uses at any given instant.

"This was a quantum leap for laser technology around the world," NIF director Ed Moses said in September. But some critics of the $5 billion project wonder why the laser has yet to ignite a fusion chain reaction after three-and-a-half years in operation. Supporters counter that such groundbreaking science simply can't be rushed.

Fiscal Cliff Creeps Closer With Few Signs of Optimism

"Absurd" -- that's the word one top Republican Hill aide used to describe the plan that Treasury Secretary Timothy Geithner presented to GOP leaders yesterday to avoid the fiscal cliff.

And an aide to House Speaker Boehner described the White House's offer as "completely unrealistic" and "a break with reality."

Meanwhile, a top Democratic insider complained to ABC's Jonathan Karl that "the Republicans have taken to screaming at us."

Sources familiar with the phone call Wednesday night between Speaker Boehner and President Obama -- which lasted 30 minutes -- told Karl it was as "unproductive" and "blunt." One source said the president did most of the taking, explaining why he will insist that tax rates go up.

"No substantive progress has been made over the last two weeks," said House Speaker John Boehner at a press conference yesterday. "It's time for the president and Congressional Democrats to tell the American people what spending cuts they're really willing to make."

With few signs of optimism in Washington and just 33 days before the end-of-the-year fiscal cliff deadline, President Obama is taking his show on the road.

ABC's Mary Bruce notes that the president is bypassing the wrangling between both sides and traveling to Hatfield, Pa. today where he will tour a toy manufacturing facility and speak to workers there.

Fiscal Cliff Negotiations Deadline: Americans Voice Concerns Watch Video

According to the White House, "the President will continue making the case for action by visiting a business that depends on middle class consumers during the holiday season, and could be impacted if taxes go up on 98 percent of Americans at the end of the year."

FROM THE SPEAKER'S OFFICE: Boehner's office gives six reasons why the Obama administration's fiscal cliff offer won't fly:

"1) Twice the Taxes: It's absolutely true that the President ran on a tax plan of raising the top two rates. That's what Americans heard from him. That yields about $800 billion in new tax revenue. He just asked for twice that. 2) Not Even the Votes in His Own Party: The Senate was barely able to pass a bill with $800 billion in new tax revenue a few months ago (51 votes). There is no chance there are votes in the Senate for anything close to $1.6 trillion. 3) Unbalanced: The President also ran on a so-called balanced approach. Apparently his idea of balance is four times as much revenue as spending cuts. 4) No Net Spending Cuts: The spending cuts they are offering (which come later) are wiped out by all the new goodies he's also requesting. (stimulus, UI, payroll, housing, etc). 5) Debt Limit Pipe Dream: Permanently doing away with the debt limit? Come on. Guess what - the debt limit is actually very popular. Raising it to infinity is not. 6) We're Far From Opening Bids: Even as an "opening bid," this offer would be ludicrous. But we're way past that. We had about seven weeks to resolve this. Three of those weeks are gone, and this is what he comes with?"

FROM THE WHITE HOUSE: White House spokesman Josh Earnest: "Right now, the only thing preventing us from reaching a deal that averts the fiscal cliff and avoids a tax hike on 98 percent of Americans is the refusal of Congressional Republicans to ask the very wealthiest individuals to pay higher tax rates. The President has already signed into law over $1 trillion in spending cuts and we remain willing to do tough things to compromise, and it's time for Republicans in Washington to join the chorus of other voices -- from the business community to middle class Americans across the country -- who support a balanced approach that asks more from the wealthiest Americans."

IAEA chief calls for "urgent" Iran diplomacy

VIENNA: The head of the UN atomic agency called Thursday for diplomatic "urgency" in the Iranian nuclear standoff, even as Tehran signalled its continued defiance of UN Security Council demands to suspend key activities.

"All countries, and the IAEA, are willing to find a diplomatic solution. If there is political will we can reach agreement," said International Atomic Energy Agency chief Yukiya Amano.

"There is an opportunity to resolve the Iranian nuclear issue diplomatically. Now is the time for all of us to work with a sense of urgency and seize the opportunity for a diplomatic solution," he said.

With Iran feeling the pinch from sanctions and US President Barack Obama freed from the constraints of a lengthy re-election campaign, conditions appear favourable to make progress in the long-running crisis.

The P5+1 powers -- the US, China, Russia, Britain, France and Germany -- held a meeting in Brussels last week and said afterwards they want talks with Iran "as soon as possible." This may happen as early as December.

But it is far from clear whether the P5+1 will want to sweeten an offer, made in talks in May and June, that for Tehran stopped short of offering sufficient sanctions relief.

Signals coming out of Iran meanwhile indicate that Tehran is not any readier to abandon its most sensitive nuclear activities, most notably uranium enrichment.

Iran's nuclear chief Fereydoon Abbasi Davani, who alleged in September that the IAEA had been infiltrated by saboteurs and "terrorists", said Wednesday Iran would continue "with force" to expand its activities.

This was in spite of four rounds of sanctions imposed by the UN Security Council, which in combination with additional Western restrictions began to cause real problems for the Iranian economy this year.

Abbasi Davani also said Iran would "soon test" its new heavy water nuclear reactor at Arak, which Western nations fear could produce weapons-grade plutonium.

Parallel diplomatic efforts between the IAEA and Iran, focused on what the agency calls "overall, credible" evidence of past weapons research work, are meanwhile set to resume on December 13 in Tehran.

Amano said Thursday that after several rounds of fruitless talks this year, including his visit to Tehran in May, he did not want another instance of "going around in circles."

His comments came as the IAEA's board of governors met in Vienna for a session dominated, as usual, by Iran's nuclear programme.

The IAEA's latest report on November 16 said Iran was ready to double production at its Fordo facility, a key site dug into a mountain, enriching uranium to purities of 20 percent, close to the level needed for bomb.

The IAEA also said that Fordo's final machinery had been installed but was not yet ready to be put into operation. Once it is, Iran will be able to triple its current monthly output of 20-percent enriched uranium to some 45 kilos (100 pounds).

Israel's "red line" for military action is thought to be when Iran has produced around 250 kilos. That would be enough, if further enriched -- although such a move would be quickly detected by the IAEA -- for one nuclear weapon.

Supporting however Iran's argument that its programme is for peaceful means is the IAEA's finding that of the around 230 kilos of enriched uranium produced so far, 95 kilos have been converted for use as fuel for a reactor producing nuclear medicines.

The rate of conversion has however slowed dramatically, indicating possible technical problems, and once Fordo is fully up and running, Iran will be producing far more material than its civilian facilities need, experts say.

Heavy snowfall in higher reaches of Uttarakhand

DEHRADUN: The higher reaches of the mountains in Kumaon and Garhwal regions of Uttarakhand today received the season's first heavy snowfall even as icy winds swept the plains.

Incessant rains made way for heavy snowfall in Badrinath, Kedarnath, Gangotri, Yamnotri, Auli and Harsil in Garhwal and Dharchula and Munsyari in Kumaon.

Rains lashed Dehradun in the afternoon making the day temperature drop sharply from yesterday's 24 degrees Celsius to 20 degrees Celsius, the MeT department said.

The minimum temperature recorded in the capital today was 7.6 degrees Celsius, a notch below yesterday's 8.6, it said.

Caterpillar Fungus Has Anti-Inflammatory Properties

In the Tibetan mountains, a fungus attaches itself to a moth larva burrowed in the soil. It infects and slowly consumes its host from within, taking over its brain and making the young caterpillar move to a position from which the fungus can grow and spore again.

Sounds like something out of science fiction, right? But for ailing Chinese consumers and nomadic Tibetan harvesters, the parasite called cordyceps means hope—and big money. Chinese markets sell the "golden worm," or "Tibetan mushroom"—thought to cure ailments from cancer to asthma to erectile dysfunction—for up to $50,000 (U.S.) per pound. Patients, following traditional medicinal practices, brew the fungal-infected caterpillar in tea or chew it raw.

Now the folk medicine is getting scientific backing. A new study published in the journal RNA finds that cordycepin, a chemical derived from the caterpillar fungus, has anti-inflammatory properties.

"Inflammation is normally a beneficial response to a wound or infection, but in diseases like asthma it happens too fast and to too high of an extent," said study co-author Cornelia H. de Moor of the University of Nottingham. "When cordycepin is present, it inhibits that response strongly."

And it does so in a way not previously seen: at the mRNA stage, where it inhibits polyadenylation. That means it stops swelling at the genetic cellular level—a novel anti-inflammatory approach that could lead to new drugs for cancer, asthma, diabetes, rheumatoid arthritis, and cardiovascular-disease patients who don't respond well to current medications.

From Worm to Pill

But such new drugs may be a long way off. The science of parasitic fungi is still in its early stages, and no medicine currently available utilizes cordycepin as an anti-inflammatory. The only way a patient could gain its benefits would by consuming wild-harvested mushrooms.

De Moor cautions against this practice. "I can't recommend taking wild-harvested medications," she says. "Each sample could have a completely different dose, and there are mushrooms where [taking] a single bite will kill you."

Today 96 percent of the world's caterpillar-fungus harvest comes from the high Tibetan Plateau and the Himalayan range. Fungi from this region are of the subspecies Ophiocordyceps sinensis, locally known as yartsa gunbu ("summer grass, winter worm"). While highly valued in Chinese traditional medicine, these fungi have relatively low levels of cordycepin. What's more, they grow only at elevations of 10,000 to 16,500 feet and cannot be farmed. All of which makes yartsa gunbu costly for Chinese consumers: A single fungal-infected caterpillar can fetch $30.

Brave New Worm

Luckily for researchers, and for potential consumers, another rare species of caterpillar fungus, Cordyceps militaris, is capable of being farmed—and even cultivated to yield much higher levels of cordycepin.

De Moor says that's not likely to discourage Tibetan harvesters, many of whom make a year's salary in just weeks by finding and selling yartsa gunbu. Scientific proof of cordycepin's efficacy will only increase demand for the fungus, which could prove dangerous. "With cultivation we have a level of quality control that's missing in the wild," says de Moor.

"There is definitely some truth somewhere in certain herbal medicinal traditions, if you look hard enough," says de Moor. "But ancient healers probably wouldn't notice a 10 percent mortality rate resulting from herbal remedies. In the scientific world, that's completely unacceptable." If you want to be safe, she adds, "wait for the medicine."

Ancient Chinese medical traditions—which also use ground tiger bones as a cure for insomnia, elephant ivory for religious icons, and rhinoceros horns to dispel fevers—are controversial but popular. Such remedies remain in demand regardless of scientific advancement—and endangered animals continue to be killed in order to meet that demand. While pills using cordycepin from farmed fungus might someday replace yartsa gunbu harvesting, tigers, elephants, and rhinos are disappearing much quicker than worms.

Death at School: Parents Protest Dangerous Discipline for Autistic, Disabled Kids

Thousands of autistic and disabled schoolchildren have been injured and dozens have died after being restrained by poorly trained teachers and school aides who tried to subdue them using at times unduly harsh techniques, an ABC News investigation has found.

With no agreed upon national standards for how teachers can restrain an unruly child, school officials around the country have been employing a wide array of methods that range from sitting on children, to handcuffing them, even jolting them with an electric shock at one specialized school. Some have locked children in padded rooms for hours at a time. One Kentucky teacher's aide is alleged to have stuffed 9-year-old Christopher Baker, who is autistic and was swinging a chair around him, into a draw-string duffle bag.

"When I got to the end of the hall and saw the bag, I stood there like, 'Hmmm, what in the world?'" the boy's mother, Sandra Baker, recalled in an interview with ABC News. She had arrived at the school to find her son wriggling inside the "sensory bag." "It was really heartbreaking to walk up and see him in that."

Earlier this year, Sheila Foster's son Corey, 16, was the latest child to die at school, when staff members at a special needs facility in Yonkers, New York held him face down for allegedly refusing to get off the basketball court. Sheila Foster said witnesses later informed her that Corey told the staffers he couldn't breathe, but they allegedly persisted, reportedly telling him, "If you can talk, you can breathe." The school said this account is not substantiated.

In an interview that will air on "Nightline" Thursday, Sheila Foster said she watches the time-lapse security video of her son nearly every day, hoping for a different ending. "Every time just looking at these pictures, I know I won't feel him hug me anymore, or say, 'I love you mommy,'" she said. "That was the last time he was alive and I want to see that."

How to safely handle an out-of-control student has been a longstanding issue for parents whose children attend special schools for those with autism or with behavioral or developmental problems. But experts told ABC News it has become increasingly vexing for officials in traditional public schools as they have sought to accommodate children with special needs. Many of the schools provide little or no training to teachers and staff for how to intervene when the student misbehaves. That has left teachers and school administrators to find their own solutions, at times with terrible outcomes.

Germany eyes September 22 for election

BERLIN: Germany will likely hold a federal election on September 22 next year, a government source told AFP on Wednesday, after the majority of the country's 16 states agreed on that date.

The interior ministry would inform the political parties of the states' choice next week, the source added. The official date must be cleared by German President Joachim Gauck after a decision in cabinet.

The Die Zeit weekly said the parties and cabinet were likely to agree on Sunday, September 22.

The election will pit conservative Chancellor Angela Merkel, named by Forbes magazine as the world's most powerful woman for six of the past seven years, against former finance minister Peer Steinbrueck from the centre-left Social Democrats (SPD).

A poll for Stern Magazine and RTL television on Wednesday put Merkel's Christian Democrats and their Bavarian sister party, the Christian Social Union, at 37 percent and the SPD at 26 percent.

Merkel's current coalition partners, the business-friendly Free Democrats that propelled her to power in 2009, have plunged in the polls and are now at four percent, not enough to win parliamentary seats.

The ecologist Greens, with 16 percent, are the preferred coalition partners of the SPD.

Other parties in the running are the far-left Linke (eight percent in the Stern/RTL poll) and the upstart Pirate Party, campaigning for Internet freedom, with four percent.

The most likely outcome is a third term for Merkel at the head of a CDU-led coalition, but her partner is less clear.

One option is a "Grand Coalition" of CDU and SPD, similar to that which governed Europe's top economy from 2005 to 2009.

Other possibilities include an SPD-Green coalition or even, much less likely, an alliance between the CDU and the Greens.

Amit Shah, former Gujarat home minister, gets BJP ticket

NEW DELHI: Former Gujarat home minister Amit Shah, accused in the Soharabuddin Sheikh and Tulsi Prajapati staged shootout cases, will contest in the upcoming state assembly elections.

Shah will contest from Naranpura in Ahmedabad.

His name features in the second list of candidates released by the Bharatiya Janata Party (BJP) in the capital Wednesday.

Shah won last time from Sarkhej assembly constituency with a margin of over 2.50 lakh votes.

After delimitation, Sarkhej is now divided into three constituencies -- Vejalpur, Ghatlodia and Naranpura.

Shah is a close aide of Gujarat Chief Minister Narendra Modi.

In September, Shah had returned to Gujarat after a gap of two years, following the Supreme Court judgment allowing him to re-enter the state. The apex court rejected the Central Bureau of Investigation (CBI) plea to cancel the bail granted to Shah in the Sohrabuddin Sheikh staged shootout case.

Since his return to Ahmedabad, Shah had been keeping a low profile. He has stayed away from public functions, and does not interact with the media.

The CBI has, in its charge sheet, named Shah the prime accused in the Tulsi Prajapati staged shootout case.

Acting on a petition filed by Shah, the Supreme Court had stayed all proceedings in the Prajapati case.

Besides Shah, other high-profile names in the second list of BJP candidates for the Gujarat assembly polls are: Social Justice and Empowerment minister Fakirbhai Vaghela, from Vadgam (Banaskantha); Health & Family Welfare Minister Jaynarayan Vyas, from Sidhpur (Patan); Education Minister Ramanlal Vora, from Idar (Sabarkantha); and Anandiben Patel from Ghatlodiya (Ahmedabad).

The list has named candidates for 89 of 95 seats that will see polling in the second phase Dec 17.

Six candidates would be named later.

Among the BJP leaders attending the meeting which preceded the release of the list were BJP Parliamentary Party chairman L.K. Advani, Leader of Opposition (Lok Sabha) Sushma Swaraj, and Leader of Opposition (Rajya Sabha) Arun Jaitley, besides members of the Central Election Committee of the party.

The meeting was presided over by party president Nitin Gadkari.

The two-phase Gujarat assembly elections will be held Dec 13 and 17.

Counting of votes will take place Dec 20.

Pictures: Falcon Massacre Uncovered in India

A young boy can sell bundles of fresh Amur falcons (pictured) for less than five dollars. Still, when multiplied by the thousands of falcons hunters can catch in a day, the practice can be a considerable financial boon to these groups.

Since discovering the extent of Amur hunting in Nagaland this fall, Conservation India has taken the issue to the local Indian authorities.

"They have taken it very well. They've not been defensive," Sreenivasan said.

"You're not dealing with national property, you're dealing with international property, which helped us put pressure on [them]." (Related: "Asia's Wildlife Trade.")

According to Conservation India, the same day the group filed their report with the government, a fresh order banning Amur hunting was issued. Local officials also began meeting with village leaders, seizing traps and confiscating birds. The national government has also requested an end to the hunting.

Much remains to be done, but because the hunt is so regional, Sreenivasan hopes it can eventually be contained and stamped out. Authorities there, he said, are planning a more thorough investigation next year, with officials observing, patrolling, and enforcing the law.

"This is part of India where there is some amount of acceptance on traditional bush hunting," he added. "But at some point, you draw the line."

Susan Rice Made Allies, Enemies Before Benghazi

United Nations Ambassador Susan Rice, on Capitol Hill this week answering questions about her role after the U.S. consulate attack in Benghazi, has become yet another player in the divide between the left and right, with her possible nomination as the next Secretary of State hanging in the balance.

But who was Susan Rice before she told ABC's "This Week" and other Sunday morning shows the attack was a spontaneous response to an anti-Islam film and not a premeditated act of terror? Four Americans died in the September attack.

Unlike many in government, Rice holds a rare claim to Washington, D.C.: she's a local. She hails from a prominent family with deep ties to the Democratic Party. She was born Nov. 17, 1964 to Emmett Rice, a deputy director at the Treasury Department who served as a member of Jimmy Carter's Federal Reserve board, and Lois Dickson Rice, a former program officer at the Ford Foundation who is now a higher education expert at the Brookings Institution.

As a high school student at the all-girl National Cathedral School in Washington, Rice was known as an overachiever; valedictorian, star athlete and class president. After graduating high school in 1982, she went on to study history at Stanford, where she graduated as a Truman scholar and junior Phi Beta Kappa. Rice also attended Oxford as a Rhodes Scholar.

The family has roots in Maine. In an interview with the Portland Press Herald in 2008, Lois Dickson Rice said that she held the same high expectations for her children as her mother had held for her. According to the paper, Ambassador Rice's drive to achieve spanned generations. Her maternal grandmother, an immigrant from Jamaica, was named Maine State Mother of the Year in 1950. Rice's father was only the second African-American man to be chosen for the Federal Reserve board.

Two years out of Stanford, Rice joined Massachusetts Democrat Michael Dukakis as a foreign policy aide during his 1988 run for president. After his defeat, Rice tried her hand in the private sector, where she went on to work as a management consultant with McKinsey and Company. After President Clinton's election in 1992, she joined Clinton's National Security Council, eventually joining her mentor, former Secretary of State Madeleine Albright. She served as Assistant Secretary of State for African Affairs.

A profile of the diplomat from Stanford paints the Rices and Albrights as old family friends.

"The Rice and Albright kids went to school together and shared meals at Hamburger Hamlet," Stanford Magazine reported in 2000.
