James Cameron Relives Voyage to Ocean’s Deepest Spot

SAN FRANCISCO — The first thing James Cameron saw 7 miles below the sea was man-made: tracks from a remotely operated vehicle.

“When I got to the bottom, I saw skid marks from the ROV,” Cameron said yesterday (Dec. 4) here at the annual meeting of the American Geophysical Union, referring to a 2009 survey by the Monterey Bay Aquarium Research Institute. Scientific results of the film director’s expedition to the Mariana Trench were presented at the meeting this week, and Cameron and the researchers described the highlights to a packed crowd.

Cameron reported a new, corrected depth for his landing — 35,803 feet (10,912 meters) — which beats by five feet (1.5 m) the record set by U.S. Navy Lt. Don Walsh and Jacques Piccard in 1960 at the same spot. However, “because the error [calculating the depth] on Don’s dive is much greater, we’re just going to have to call it a tie,” Cameron said.

Deepsea Challenger

Cameron’s Deepsea Challenger expedition made dives to the New Britain Trench and the Mariana Trench in the southwestern Pacific Ocean between Jan. 31 and April 3, with one manned dive by Cameron to the Mariana’s Challenger Deep, the deepest spot in any ocean.

Unusual, never-before-seen species were snared and brought back to the surface. A bizarre microbial mat community was discovered living on altered rocks in the Sirena Deep, another deep pool 6.77 miles (10.9 kilometers) below the surface.

Changes in temperature and salinity starting at 26,200 feet (8 km) deep hint at an unknown current coming into the Challenger Deep, said Doug Bartlett, a microbiology professor at the Scripps Institution of Oceanography at UC San Diego.

The filmmaker journeyed inside a high-tech lime-green machine — a steel sphere encased in foam — dubbed the Deepsea Challenger. The expedition traveled with two unmanned seafloor “landers” — large contraptions hoisted over the side of a ship and dropped to the seafloor. Once on the bottom, bait attached to the lander lured seafloor creatures to the craft, and a suite of instruments took samples, photographs and data. [Images: James Cameron's Historic Deep-Sea Dive]

The two contraptions working together proved to be a very good system, Cameron said. “We could rendezvous on the bottom and see the results of that bait running for six to eight hours, and that’s how Doug could find a new species of giant arthropod,” Cameron said.

Challenging journey

The March 26 dive proved to be a physical and mental challenge for Cameron. “I did yoga for six months so I could contort myself into the sphere,” he said.

As he sank through the water, Cameron said he “burned though my whole checklist,” designed to distract him during the long hours of the dive. “I still had 3,000 meters left to go with pretty much nothing left to do but sit quietly and think about the pressure building up around the hull,” he said.

The sub touched down gently, and Cameron immediately took a sample of the seafloor, as planned. This was a good contingency, because the sub’s hydraulic fluid line then burst, leaving him unable to collect more samples.

To his surprise, the sub’s voice communications worked perfectly. “We actually expected they wouldn’t, and I would have to default to texting,” he said. “Texting while driving is not a good thing, especially if you’re using two hands to operate seven joysticks and you’re 7 miles down.”

Cameron first drove the sub about 200 meters, finding the seafloor elevation stayed the same. In fact, Challenger Deep turned out to be remarkably flat, and the sub was easy to drive. “The vehicle was quite nimble, the sub’s yaw rate was very good,” he said. (Yaw describes the left-to-right rotation of a craft.)

A quick return

After about three hours, some of the submersible’s batteries had low charge readings, the steering was problematic, and it was time to return to the surface. The mission should have lasted five to six hours. “I hate this. I hated having to go back,” Cameron recalled thinking.

The trip to the top was mercifully short at 73 minutes. The submersible covered nearly 7 miles in a little over an hour — slow in a car, but like riding a missile for a human in a metal ball. Cameron said the surface trip is when he noticed the aches and pains from the cramped sub. “That’s when your butt is really sore, and when you notice how much it hurts.” [Infographic: James Cameron's Mariana Trench Dive]

The sub now sits in a barn in Santa Barbara, waiting for Cameron or another group with enough money to send it back to the deep ocean. He declined to say how much it cost to build and mount the expedition.

“I would love for the sub to dive again,” he said. “I personally feel that we just barely got started before we had to turn back and there’s just so much out there.”

“And if not, at the very least, the technical innovations can be incorporated into other vehicle platforms,” Cameron added. “As far as I’m concerned, it’s an open source situation.”

Jason Aldean's Holiday Plans: Visiting Santa with His Kids

By Eileen Finan

12/08/2012 at 06:30 PM EST

Jessica Ussery and Jason Aldean

Bauer-Griffin

After a year of professional highs – and personal lows – Jason Aldean is looking forward to a quiet holiday with family.

"I'm on the road so much during the year, so what I look forward to the most is being home with my family, " he told PEOPLE at the taping of the CMT Artists of the Year special (airing Saturday at 10/9 CT), where he walked the red carpet hand-in-hand with his wife, Jessica.

Aldean says being with Jessica and their daughters – Keeley, 10, and Kendyl, 5 – and doing "things like taking the girls to the mall to shop or to see Santa Claus" are on his holiday must-do list. "Things that simple to me are really cool."

Looking back at 2012, some highlights for the country star include releasing a chart-topping album and playing sold out stadiums.

But Aldean also faced personal hurdles when photos surfaced showing him getting affectionate with another woman. Still, for the singer, who publicly apologized for his behavior, life is good.

"This year, the tour went really well, the album has done really well, and good stuff has definitely outweighed the bad," he says. "All that other stuff is kind of in the past and we're just looking to have a great year in 2013."

Smokers celebrate as Wash. legalizes marijuana

SEATTLE (AP) — The crowds of happy people lighting joints under Seattle's Space Needle early Thursday morning with nary a police officer in sight bespoke the new reality: Marijuana is legal under Washington state law.

Hundreds gathered at Seattle Center for a New Year's Eve-style countdown to 12 a.m., when the legalization measure passed by voters last month took effect. When the clock struck, they cheered and sparked up in unison.

A few dozen people gathered on a sidewalk outside the north Seattle headquarters of the annual Hempfest celebration and did the same, offering joints to reporters and blowing smoke into television news cameras.

"I feel like a kid in a candy store!" shouted Hempfest volunteer Darby Hageman. "It's all becoming real now!"

Washington and Colorado became the first states to vote to decriminalize and regulate the possession of an ounce or less of marijuana by adults over 21. Both measures call for setting up state licensing schemes for pot growers, processors and retail stores. Colorado's law is set to take effect by Jan. 5.

Technically, Washington's new marijuana law still forbids smoking pot in public, which remains punishable by a fine, like drinking in public. But pot fans wanted a party, and Seattle police weren't about to write them any tickets.

In another sweeping change for Washington, Gov. Chris Gregoire on Wednesday signed into law a measure that legalizes same-sex marriage. The state joins several others that allow gay and lesbian couples to wed.

The mood was festive in Seattle as dozens of gay and lesbian couples got in line to pick up marriage licenses at the King County auditor's office early Thursday.

King County and Thurston County announced they would open their auditors' offices shortly after midnight Wednesday to accommodate those who wanted to be among the first to get their licenses.

Kelly Middleton and her partner Amanda Dollente got in line at 4 p.m. Wednesday.

Hours later, as the line grew, volunteers distributed roses and a group of men and women serenaded the waiting line to the tune of "Chapel of Love."

Because the state has a three-day waiting period, the earliest that weddings can take place is Sunday.

In dealing with marijuana, the Seattle Police Department told its 1,300 officers on Wednesday, just before legalization took hold, that until further notice they shall not issue citations for public marijuana use.

Officers will be advising people not to smoke in public, police spokesman Jonah Spangenthal-Lee wrote on the SPD Blotter. "The police department believes that, under state law, you may responsibly get baked, order some pizzas and enjoy a 'Lord of the Rings' marathon in the privacy of your own home, if you want to."

He offered a catchy new directive referring to the film "The Big Lebowski," popular with many marijuana fans: "The Dude abides, and says 'take it inside!'"

"This is a big day because all our lives we've been living under the iron curtain of prohibition," said Hempfest director Vivian McPeak. "The whole world sees that prohibition just took a body blow."

Washington's new law decriminalizes possession of up to an ounce for those over 21, but for now selling marijuana remains illegal. I-502 gives the state a year to come up with a system of state-licensed growers, processors and retail stores, with the marijuana taxed 25 percent at each stage. Analysts have estimated that a legal pot market could bring Washington hundreds of millions of dollars a year in new tax revenue for schools, health care and basic government functions.

But marijuana remains illegal under federal law. That means federal agents can still arrest people for it, and it's banned from federal properties, including military bases and national parks.

The Justice Department has not said whether it will sue to try to block the regulatory schemes in Washington and Colorado from taking effect.

"The department's responsibility to enforce the Controlled Substances Act remains unchanged," said a statement issued Wednesday by the Seattle U.S. attorney's office. "Neither states nor the executive branch can nullify a statute passed by Congress."

The legal question is whether the establishment of a regulated marijuana market would "frustrate the purpose" of the federal pot prohibition, and many constitutional law scholars say it very likely would.

That leaves the political question of whether the administration wants to try to block the regulatory system, even though it would remain legal to possess up to an ounce of marijuana.

Alison Holcomb is the drug policy director of the American Civil Liberties Union of Washington and served as the campaign manager for New Approach Washington, which led the legalization drive. She said the voters clearly showed they're done with marijuana prohibition.

"New Approach Washington sponsors and the ACLU look forward to working with state and federal officials and to ensure the law is fully and fairly implemented," she said.

Wall Street Week Ahead: "Cliff" worries may drive tax selling

NEW YORK (Reuters) - Investors typically sell stocks to cut their losses at year end. But worries about the "fiscal cliff" - and the possibility of higher taxes in 2013 - may act as the greatest incentive to sell both winners and losers by December 31.

The $600 billion of automatic tax increases and spending cuts scheduled for the beginning of next year includes higher rates for capital gains, making tax-loss selling even more appealing than usual.

Tax-related selling may be behind the weaker trend in the shares of market leader Apple , analysts said. The stock is down 20 percent for the quarter, but it's still up nearly 32 percent for the year.

Apple dropped 8.9 percent in this past week alone. For a stock that gained more than 25 percent a year for four consecutive years, the embedded capital gains suddenly look like a selling opportunity if one's tax bill is going to jump sharply just because the calendar changes.

"Tax-loss selling is always a factor (but) tax-gains selling has been a factor this year," said Paul Mendelsohn, chief investment strategist at Windham Financial Services in Charlotte, Vermont.

"You have a lot of high-net-worth individuals in taxable accounts, and that could be what's affecting stocks like Apple. If you look at the stocks that people have their largest gains in, they seem to be under a little bit more pressure here than usual."

Of this year's top 20 performers in the S&P 1500 index, which includes large, small and mid-cap stocks, all but four have lost ground in the last five trading sessions.

The rush to avoid higher taxes on portfolio gains could cause additional weakness.

The S&P 500 ended the week up just 0.1 percent after another week of trading largely tied to fiscal cliff negotiation news, which has pushed the market in both directions.

A PAIN PILL FROM THE FED?

Next week's Federal Reserve meeting could offer some relief if policymakers announce further plans to help the lackluster U.S. economy. The Federal Open Market Committee will meet on Tuesday and Wednesday. The policy statement is expected at about 12:30 p.m. on Wednesday after the conclusion of the meeting - the Fed's last one for the year.

Friday's jobs report showing non-farm payrolls added 146,000 jobs in November eased worries that Superstorm Sandy had hit the labor market hard.

"After the FOMC meeting, I think it's going to be downhill from there as worries about the fiscal cliff really take center stage and prospects of a deal become less and less likely," said Mohannad Aama, managing director of Beam Capital Management LLC in New York.

"I think we are likely to see an escalation in profit-taking ahead of tax rates going up next year," he said.

MORE VOLUME AND VOLATILITY

Volume could increase as investors try to shift positions before year end, some analysts said.

While most of that would be in stocks, some of the extra trading volume could spill over into options, said J.J. Kinahan, TD Ameritrade's chief derivatives strategist.

Volatility could pick up as well, and some of that is already being seen in Apple's stock.

"The actual volatility in Apple has been very high while the market itself has been calm. I expect Apple's volatility to carry over into the market volatility," said Enis Taner, global macro editor at RiskReversal.com, an options trading firm in New York.

Shares of Apple, the largest U.S. company by market value, registered their worst week since May 2010. In another bearish sign, the stock's 50-day moving average fell to $599.52 - below its 200-day moving average at $601.38.

"There's a lot of tax-related selling happening now, and it will continue to happen. Apple is an example, even (though) there are other factors involved with Apple," Aama said.

While investors may be selling stocks to avoid higher taxes in 2013, companies may continue to announce special and accelerated dividend payments before year end. Among the latest, Expedia announced a special dividend of 52 cents a share to be paid on December 28.

To be sure, the big sell-off in stocks following the November 6 election was likely related to tax selling, making it hard to judge how much more is to come.

Bruce Zaro, chief technical strategist at Delta Global Asset Management in Boston, said there's a decent chance that the market could rally before year end.

"Even with little or spotty news that one would put in the positive bucket regarding the (cliff) negotiations, the market has basically hung in there, and I think it's hung in there in anticipation of something coming," he said.

Egyptian military says only dialogue can avert disaster

CAIRO (Reuters) - Egypt's military, stepping into a crisis pitting Islamist President Mohamed Mursi against opponents who accuse him of grabbing excessive power, said on Saturday only dialogue could avert "catastrophe".

State broadcasters interrupted their programs to read out an army statement telling feuding factions that a solution to the upheaval in the most populous Arab nation should not contradict "legitimacy and the rules of democracy".

That sounded like a swipe at protesters who have besieged the palace of the freely elected president and called for his removal, going beyond mainstream opposition demands for him to retract a decree that expanded his powers.

The statement also called for a "serious" national dialogue - perhaps one more credible than talks convened by Mursi on Saturday in the absence of opposition leaders. They insist he must first scrap his November 22 decree, defer next week's popular vote on a new constitution and allow the text to be revised.

Deep rifts have emerged over the destiny of a country of 83 million where the end of Hosni Mubarak's 30 years of military-backed one-man rule led to a messy army-led transition, during which the Muslim Brotherhood and its allies won two elections. Many Egyptians crave stability and economic recovery.

The spokesman for the main Islamist coalition demanded that the referendum go ahead on time on the constitution drafted by an Islamist-led assembly from which liberals had walked out.

The army, which ran Egypt for months after Mubarak fell in February 2011, again cast itself primarily as the neutral guarantor of the nation. A military source said there was no plan to retake control of the country or its turbulent streets.

"DARK TUNNEL"

"The armed forces affirm that dialogue is the best and only way to reach consensus," the statement said. "The opposite of that will bring us to a dark tunnel that will result in catastrophe and that is something we will not allow."

Mursi's office said the president opened his "national dialogue" with about 40 political and other public figures discussing "means to reach a solution to differences over the referendum...and the constitutional decree".

Prime Minister Hisham Kandil told an Egyptian television channel that the talks had led to creating a committee to review Mursi's November 22 decree and to work out legal ways to postpone the referendum. He said a new decree could be issued.

"All options are on the table to reach consensus," he said, adding that it was vital to take action to shore up Egypt's economy that has been battered by the turmoil.

The main opposition coalition, the National Salvation Front, which boycotted Mursi's dialogue repeated its call on Saturday for scrapping the decree and the referendum on the constitution.

Instability in Egypt worries the West, especially the United States, which has given Cairo billions of dollars in military and other aid since it made peace with Israel in 1979.

The army might be pushing the opposition to join dialogue and Mursi to do more to draw them in, said Hassan Abu Taleb of the Al Ahram Center for Political and Strategic Studies.

He discounted the chance of direct military intervention, adding: "They realize that interfering again in a situation of civil combat will squeeze them between two rocks."

However, the military did seem poised to take a more active role in security arrangements for the December 15 referendum.

A cabinet source said the cabinet had discussed reviving the army's ability to make arrests if it were called upon to back up police, who are normally in charge of election security.

According to the state-run daily al-Ahram, an expanded military security role might extend to the next parliamentary election and, at the president's discretion, even beyond that.

The army issued its statement while protesters were still camped out by the gates of the presidential palace.

The tens of thousands of Mursi foes who surged past tanks and barbed wire to reach the palace gates on Friday night had dispersed. But a hard core stayed overnight in a score of tents.

"LEAVE"

Some had spray-painted "Down with Mursi" on tanks of the elite Republican Guard posted there after clashes between rival groups killed at least seven people and wounded 350 this week.

Others draped the tanks with posters of Mursi and the word "Leave" scored across his face in red letters.

"We are no longer calling for scrapping the decree and delaying the referendum," Samir Fayez, a Christian protester at the palace, said. "We have one demand in five letters: leave."

Nearby, a Mursi supporter named Mohamed Hassan was quietly observing the scene. He suggested that the Muslim Brotherhood and its ultra-orthodox Salafi Islamist allies could easily overwhelm their foes if they chose to mobilize their base.

"The Brotherhood and Salafis by themselves are few but they have millions of supporters who are at home and haven't taken it to the streets yet," murmured the 40-year-old engineer.

The Muslim Brotherhood's supreme guide, Mohamed Badie, denounced opposition protests that have swirled around the walls of Mursi's palace, saying they "ruin legitimacy".

Badie said eight people, all of them Brotherhood members, had been killed this week and urged the interior minister to explain why police had failed to prevent assailants from torching the organization's headquarters and 28 other offices.

"Get angry with the Brotherhood and hate us as much as you like, but be reasonable and preserve Egypt's unity," he told a news conference. "We hope everyone gets back to dialogue."

The well-organized Brotherhood, which thrust Mursi from obscurity to power, remains his surest source of support.

Alicia Keys (Almost) Gets Auctioned Off in N.Y.C.

Caught in the Act

12/07/2012 at 06:35 PM EST

Jennifer Hudson and Alicia Keys at the Black Ball "REDUX"

Stephen Lovekin/Child12/Wireimage

Alicia Keys was definitely on fire Thursday night.

The Grammy-winning singer hosted, performed – and was nearly auctioned off – at the Black Ball "REDUX," an annual event for her organization Keep A Child Alive, which assists those affected by AIDS in Africa, held at New York's legendary Apollo Theatre. The event, which was rescheduled due to Hurricane Sandy, honored Oprah Winfrey for her work in Africa and India and raised $2.9 million.

Keys took to the red carpet in a floor-length, form-fitting Alaia gown and could hardly control her excitement over her new album Girl on Fire, which debuted at No. 1 on the Billboard charts this week. "It's a joy that I can't even express," the singer said of her fifth chart-topping album.

And she was just as enthused over the recent Grammy nominations announced this week. Asked who she's rooting for, Keys started singing R&B star Frank Ocean's hit single "Thinking About You." "I'm so excited for him!" she said.

Padma Lakshmi, Bonnie Raitt, Gayle King and Keys's husband Swizz Beatz also hit the carpet before heading inside for the show, where guests dined on Moroccan lamb chops and steak tartare taquitos, crafted by celebrity chef Marcus Samuelsson.

Before taking the stage with Jennifer Hudson and Raitt, Keys gave the award to Winfrey, who had never been to the famous Harlem theatre. But it was during the auction, hosted by Whoopi Goldberg, that the singer got an offer she had to refuse.

One wealthy guest said he'd up his bid from $100,000 to $250,000 for a trip to South Africa – if Keys would join him and his friends. "I'll go for a little more," Keys quipped. – Janine Rayford

Dow, S&P rise on jobs, but Apple bites Nasdaq again

NEW YORK (Reuters) - The Dow and the S&P 500 advanced modestly on Friday, though another sell-off in Apple depressed technology shares and kept the Nasdaq negative, overshadowing a sharply better-than-expected jobs report.

Trading was light, continuing the week's trend of slight moves and anemic volume. The S&P 500 ended up a mere 0.1 percent for the week, following several volatile sessions that repeatedly pushed it in and out of positive territory. The benchmark index is just 3.8 percent below the 2012 intraday high of 1,474.51 reached in mid-September.

Equities opened higher after the non-farm payrolls report, which showed 146,000 jobs added in November, far more than had been expected, while the U.S. unemployment rate dropped to 7.7 percent. A sour reading on consumer sentiment caused an erosion of those gains, though markets rebounded going into the close.

The Thomson Reuters/University of Michigan's consumer sentiment index for early December fell to its lowest level since August. Sentiment fell on growing concerns over the "fiscal cliff" debates in Washington, which have been a major factor preventing broader moves as well.

"We're not as concerned as we were a few months ago because of improvement like you can see in the employment number, but there's such a wild card over the cliff," said Bruce McCain, chief investment strategist at Key Private Bank in Cleveland, Ohio. "There are such concerns about what could happen that markets will be overhung until a resolution is more certain."

One of the biggest drags on the Nasdaq was Apple which fell 2.6 percent to $533.25, extending its losses for the week to 8.9 percent. This was the worst week for the stock since May 2010, and with the losses, the stock of the largest U.S. company by market value is now down 24.4 percent from an all-time intraday high reached in late September.

In Friday's session, Apple's 50-day moving average fell to $599.52 - below its 200-day moving average at $601.38. The weakness drove the S&P information technology sector <.gspt> lower. The index fell 0.6 percent and was the weakest of the S&P 500's 10 major industry sectors on Friday.

The Dow Jones industrial average <.dji> gained 81.09 points, or 0.62 percent, to 13,155.13 at the close. The Standard & Poor's 500 Index <.spx> rose 4.13 points, or 0.29 percent, to 1,418.07. The Nasdaq Composite Index <.ixic> slipped 11.23 points, or 0.38 percent, to close at 2,978.04.

For the week, the Nasdaq is down 1.1 percent, hurt largely by the decline in Apple.

The Dow, which does not count Apple as a component, rose 1 percent for its third straight week of gains. The S&P 500 is also up for three straight weeks, rising 4.3 percent over that period.

The equity market has regained most of the ground it lost following President Barack Obama's re-election as markets turned their focus to the coming "fiscal cliff." Market response to the macroeconomic data remained muted as negotiations continued to command investor attention.

U.S. House Speaker John Boehner said that talks this week with President Barack Obama produced no progress, and he renewed his demand that the president provide a new offer to avert the series of tax increases and spending cuts that are likely to hurt economic demand in 2013.

Material shares <.gspm> were the strongest performers of the day, with that index up 0.8 percent. Freeport-McMoRan Copper & Gold Co gained 2.9 percent to $31.70 while Dow Chemical added 2.2 percent to $30.30.

Amarin Corp fell 18.9 percent to $9.69 after the biopharmaceutical company raised $100 million in financing to help it launch its heart drug, Vascepa, but disappointed investors, who had hoped for a sale or partnership.

CombiMatrix Corp shares more than quadrupled, soaring 336.6 percent to $8.60 after the company said two studies published in a medical journal favored technology it uses for prenatal diagnosis of genetic abnormalities over traditional technologies.

About 52 percent of shares listed on the New York Stock Exchange closed higher while slightly more than 50 percent of Nasdaq-listed stocks closed lower.

Volume was light, with about 5.47 billion shares changing hands on the New York Stock Exchange, the Nasdaq and NYSE MKT, below the daily average so far this year of about 6.48 billion shares.

Egyptian opposition to shun Mursi's national dialogue

CAIRO (Reuters) - Prime Minister Mohamed Mursi was expected to press ahead on Saturday with talks on ways to end Egypt's worst crisis since he took office even though the country's main opposition leaders have vowed to stay away.

Cairo and other cities have been rocked by violent protests since November 22, when Mursi promulgated a decree awarding himself sweeping powers that put him above the law.

The upheaval in the most populous Arab nation, following the fall of Hosni Mubarak last year, worries the West, in particular the United States, which has given it billions of dollars in military and other aid since Egypt made peace with Israel in 1979.

Mursi's deputy raised the possibility that a referendum set for December 15 on a new constitution opposed by liberals might be delayed. But the concession only goes part-way towards meeting the demands of the opposition, who also want Mursi to scrap the decree awarding himself wide powers.

On Friday, large crowds of protesters surged around the presidential palace, breaking through barbed wire barricades and climbing on tanks guarding the seat of Egypt's first freely elected president, who took office in June.

As the night wore on, tens of thousands of opposition supporters were still at the palace, waving flags and urging Mursi to "Leave, leave".

"AS LONG AS IT TAKES"

"We will stay here for as long as it takes and will continue to organize protests elsewhere until President Mursi cancels his constitutional decree and postpones the referendum," said Ahmed Essam, 28, a computer engineer and a member of the liberal Dostour party.

Vice President Mahmoud Mekky issued a statement saying the president was prepared to postpone the referendum if that could be done without legal challenge.

Mursi's planned dialogue meeting was expected to go ahead on Saturday in the absence of most opposition factions. "Everything will be on the table," a presidential source said.

Mursi could be joined by some senior judiciary figures and politicians such as Ayman Nour, one of the candidates in Mubarak's only multi-candidate presidential race, in 2005, in which he was unsurprisingly trounced.

The opposition has demanded that Mursi rescind the decree giving himself wide powers and delay the vote set for December 15 on a constitution drafted by an Islamist-led assembly which they say fails to meet the aspirations of all Egyptians.

EXPAT VOTE DELAYED

The state news agency reported that the election committee had postponed the start of voting for Egyptians abroad until Wednesday, instead of Saturday as planned. It did not say whether this would affect the timing of voting within Egypt.

Ahmed Said, leader of the liberal Free Egyptians Party, told Reuters that delaying expatriate voting was intended to seem like a concession but would not change the opposition's stance.

The opposition organized marches converging on the palace which Republican Guard units had ringed with tanks and barbed wire on Thursday after violence between supporters and opponents of Mursi killed seven people and wounded 350.

Islamists, who had obeyed a military order for demonstrators to leave the palace environs, held funerals on Friday at Cairo's al-Azhar mosque for six Mursi partisans who were among the dead.

"With our blood and souls, we sacrifice to Islam," they chanted.

A group led by leftist opposition leader Hamdeen Sabahy has called for an open-ended protest at the palace.

Some pro-Mursi demonstrators gathered in a mosque not far from the palace, but said they would not march towards the palace to avoid a repeat of the violence that took place on Wednesday night.

In a speech late on Thursday, Mursi had refused to retract his decree or cancel the referendum on the constitution, but offered talks on the way forward after the referendum.

The National Salvation Front, the main opposition coalition, said it would not join the dialogue. The Front's coordinator, Mohamed ElBaradei, a Nobel peace laureate, dismissed the offer as "arm-twisting and imposition of a fait accompli".

ElBaradei said that if Mursi were to scrap the decree with which he awarded himself extra powers and postpone the referendum "he will unite the national forces".

Murad Ali, spokesman for the Muslim Brotherhood's Freedom and Justice Party, said opposition reactions were sad: "What exit to this crisis do they have other than dialogue?" he asked.

Zynga moves to enter US gambling market

NEW YORK (AP) — Online games company Zynga said it has asked Nevada gambling regulators for a decision that could pave the way for it to enter the U.S. gambling market.

This follows Zynga’s October disclosure that it has signed a deal to offer online poker and casino games, played with real money, in the U.K. It plans to launch those games in the first half of 2013.

Zynga Inc. said in an email late Wednesday that it is seeking an “application for a preliminary finding of suitability” from the Nevada Gaming Control Board. This, the company says, is part of its plan to enter regulated “real-money gaming,” that is, gambling markets.

Zynga has not said what it plans to do with a gaming license. But the company, whose games are played primarily on Facebook, has faltered in recent months and is looking for additional revenue sources beyond online games such as “FarmVille 2″ and “Words With Friends.”

The San Francisco-based company says the process with Nevada regulators should take 12 to 18 months. If Zynga passes the first regulatory hurdle, it can then apply for a gaming license in the state. That, the company said, takes two to three months.

Zynga’s stock rose 17 cents, or 7.1 percent, to close Thursday at $ 2.49. The company went public about a year ago, when its stock priced at $ 10 per share.
