NASA’s Alien Planet Archive Now Open to the World

Scientists with NASA’s planet-hunting Kepler spacecraft have revamped the mission’s online archive of alien worlds, opening up the database for the entire world to see.

Researchers are now posting all exoplanet sightings by the Kepler observatory into a single, comprehensive website called the “NASA Exoplanet Archive.” Instead of going through the long planet confirmation process before making data publicly available, since December of last year, scientists have started shoveling out all the data Kepler collects into a comprehensive list.

“When we make that list, right away it goes to the archive,” Kepler mission team member Steve Howell told SPACE.com during the 221st American Astronomical Society meeting in Long Beach, Calif., this month. “So the day we know about the list, the archive knows about the list. And then everybody, including us, can work on that list. But that list is dynamic so if we, or a community person, makes an observation and says, ‘Hey, I looked at this planet candidate but it’s really an eclipsing binary,’ then that entry in the archive will be changed.”

The archive has information about the size, orbital period and other metrics of any possible planet discovered and investigated by Kepler.[Gallery: A World of Kepler Planets]

“It’s all in real time,” Howell said. “The sausage-making process is exposed.”

Before the new archive was debuted, astronomers were already doing creative work with the data. One created a visually stunning video of every known Kepler planet candidate — 2,299 unconfirmed exoplanets at the time — orbiting one central point.

The Kepler team’s new “open” attitude toward data release is giving everybody, not just members of the scientific community, a chance to do some hands-on scientific research by building their own experiments, Howell said.

A group of high school students has already taken data from groups of planets observed by Kepler and mapped them against a map of known stars looking for a pattern. Howell doesn’t think they’ll see much, but he’s glad that they have the opportunity to get creative.

“The entire world can help us with this Kepler data,” Howell said. “I don’t see any downside.”

Planet Hunters, a collective of amateur astronomers, recently found 42 new alien planets using Kepler data that was publicly available prior to the launch of the new archive system.

It would be difficult for Kepler scientists to get their jobs done without the help of amateur astronomers around the globe, mission researchers said. By making the exoplanet archive more accessible, it could mean that more planets are found and confirmed in shorter amounts of time than ever before.

More people sifting through the wealth of data collected by Kepler means that scientists have a better chance of finding even more planets circling distant stars, Howell added.

Since its launch in 2009, NASA’s Kepler spacecraft has flagged more than 2,300 objects as possible alien worlds. Although only about 100 have been confirmed, scientists expect that at least 80 percent could be certifiable exoplanets.

Currently, Kepler has entered a “safe mode” after researchers spotted an issue with one of the spacecraft’s three reaction wheels that are responsible for orienting the telescope. The malfunction has stalled science observations, but researchers hope that the issue will be resolved by Sunday (Jan. 27).

2013 could be 'climate game-changer'

An ice sculpture entitled 'Minimum Monument' by Brazilian artist Nele Azevedo outside Berlin's Concert Hall, September 2, 2009.

STORY HIGHLIGHTS

• The "neglected" risk of climate change seems to be rising to the top of leaders' agendas


• Extreme weather events are costing the global economy billions of dollars each year


• Gas can be an important bridge to a lower carbon future but it's not the answer


• More investment in renewable energy is needed, with fewer risks

Editor's note: Andrew Steer is President and CEO of the World Resources Institute, a think tank that works with governments, businesses and civil society to find sustainable solutions to environmental and development challenges.

(CNN) -- As leaders gather for the World Economic Forum in Davos, signs of economic hope are upon us. The global economy is on the mend. Worldwide, the middle class is expanding by an estimated 100 million per year. And the quality of life for millions in Asia and Africa is growing at an unprecedented pace.

Threats abound, of course. One neglected risk -- climate change -- appears to at last be rising to the top of agendas in business and political circles. When the World Economic Forum recently asked 1,000 leaders from industry, government, academia, and civil society to rank risks over the coming decade for the Global Risks 2013 report, climate change was in the top three. And in his second inaugural address, President Obama identified climate change as a major priority for his Administration.

Andrew Steer

For good reason: last year was the hottest year on record for the continental United States, and records for extreme weather events were broken around the world. We are seeing more droughts, wildfires, and rising seas. The current U.S. drought will wipe out approximately 1% of the U.S. GDP and is on course to be the costliest natural disaster in U.S. history. Damage from Hurricane Sandy will cost another 0.5% of GDP. And a recent study found that the cost of climate change is about $1.2 trillion per year globally, or 1.6% of global GDP.

Shifting to low-carbon energy sources is critical to mitigating climate change's impacts. Today's global energy mix is changing rapidly, but is it heading in the right direction?

Coal is the greatest driver of carbon dioxide emissions from energy, accounting for more than 40% of the total worldwide. Although coal demand is falling in the United States -- with 55 coal-powered plants closed in the past year -- it's growing globally. The World Resources Institute (WRI) recently identified 1,200 proposed new coal plants around the world. And last year, the United States hit a record-high level of coal exports—arguably transferring U.S. emissions abroad.

Meanwhile, shale gas is booming. Production in the United States has increased nearly tenfold since 2005, and China, India, Argentina, and many others have huge potential reserves. This development can be an economic blessing in many regions, and, because carbon emissions of shale gas are roughly half those of coal, it can help us get onto a lower carbon growth path.

However, while gas is an important bridge to a low carbon future—and can be a component of such a future—it can't get us fully to where we need to be. Greenhouse gas emissions in industrial countries need to fall by 80-90% by 2050 to prevent climate change's most disastrous impacts. And there is evidence that gas is crowding out renewables.

Renewable energy -- especially solar and wind power -- are clear winners when it comes to reducing emissions. Unfortunately, despite falling prices, the financial markets remain largely risk-averse. Many investors are less willing to finance renewable power. As a result of this mindset, along with policy uncertainty and the proliferation of low-cost gas, renewable energy investment dropped 11%, to $268 billion, last year.

What do we need to get on track?

Incentivizing renewable energy investment

Currently, more than 100 countries have renewable energy targets, more than 40 developing nations have introduced feed-in tariffs, and countries from Saudi Arabia to South Africa are making big bets on renewables as a growth market. Many countries are also exploring carbon-trading markets, including the EU, South Korea, and Australia. This year, China launched pilot trading projects in five cities and two provinces, with a goal of a national program by 2015.

Removing market barriers

Despite growing demand for renewable energy from many companies, this demand often remains unmet due to numerous regulatory, financial, and psychological barriers in the marketplace.

In an effort to address these, WRI just launched the Green Power Market Development Group in India, bringing together industry, government, and NGOs to build critical support for renewable energy markets. A dozen major companies from a variety of sectors—like Infosys, ACC, Cognizant, IBM, WIPRO, and others— have joined the initiative. This type of government-industry-utility partnership, built upon highly successful models elsewhere, can spur expanded clean energy development. It will be highlighted in Davos this week at meetings of the Green Growth Action Alliance (G2A2).

De-risking investments

For technical, policy, and financial reasons, risks are often higher for renewables than fossil-based energy. Addressing these risks is the big remaining task to bring about the needed energy transformation. Some new funding mechanisms are emerging that can help reduce risk and thus leverage large sums of financing. For example, the Green Climate Fund could, if well-designed, be an important venue to raise funds and drive additional investments from capital markets. Likewise, multi-lateral development banks' recent $175 billion commitment to sustainable transport could help leverage more funds from the private and public sectors.

Some forward-looking companies are seeking to create internal incentives for green investments. For example, companies like Unilever, Johnson & Johnson, and UPS have been taking actions to reduce internal hurdle rates and shift strategic thinking to the longer-term horizons that many green strategies need.

Davos is exactly the type of venue for finding solutions to such issues, which requires leadership and coalition-building from the private and public sectors. For example, the the G2A2, an alliance of CEOs committed to addressing climate and environmental risks, will launch the Green Investment Report with precisely the goal of "unlocking finance for green growth".

Depending on what happens at Davos—and other forums and meetings like it throughout the year—2013 could just be a game-changer.

Blackhawks silence Blues 3-2 in home opener

Chicago Blackhawks forward Patrick Kane on his team's 3-2 victory over the St. Louis Blues.

In Brian Elliott's worst nightmare, he probably sees three Blackhawks breaking in alone with nary a defenseman in sight.

Unfortunately for the Blues goaltender, he was wide awake when the line of Patrick Kane, Patrick Sharp and Dave Bolland got behind pinching blueliners during the first period of Tuesday night's game at the United Center. A give-and-go between Kane and Sharp resulted in the Hawks' first goal and they carried the momentum to a 3-2 victory over the Blues before a crowd of 21,455 on hand for the home opener.

"Not too many times are you going to see where you look up and you have two guys with you on a breakaway to make it a three-on-none," said Kane, who took a return pass from Sharp and tucked a backhander past Elliott. "Me and Sharp have talked about it a lot: If we ever get a 2-on-0 it's a pretty simple play, you give it to the guy and he gives it back. Usually it's an open net but I had to pull it back to my backhand. It was exciting."

In addition to Kane's highlight-reel goal, Brent Seabrook and Viktor Stalberg also scored and Corey Crawford was solid in goal as the Hawks won their third consecutive game to start the season. They also handed the Blues — playing the second of back-to-back games — their first loss of the season in three contests.

"(Tuesday night) was our best effort, our best team game so far this season," said Hawks defenseman Duncan Keith, who had an assist and five blocked shots. "We knew it was going to be a tough game (and) … we did a good job of stepping up to that challenge."

In the second, the Hawks made it 2-0 while on the power play when Keith fired a long shot that hit Seabrook's skate en route to the goal and slid through Elliott's pads.

Early in the third, Stalberg made it a three-goal advantage when he ripped a shot from the right circle that eluded Elliott to the glove side.

Crawford entered the third period with a shutout but Andy McDonald scored to end the bid. The Hawks did not record a shutout all last season and haven't had one since Crawford pulled off the feat March 23, 2011 against the Panthers. The Blues made a game of it as T.J. Oshie followed McDonald's goal with one of his own, but the Hawks held on.

"We played a very uneven game, made some poor decisions early and you can't make mistakes against a team like Chicago," Blues coach Ken Hitchcock said.

The Hawks started a season 3-0 for the first time since the 1972-73 campaign.

"It was important for us to come out to a strong start this year, especially given the schedule with all the road games," Kane said. "To start off 3-0, you couldn't ask for a better start."

Cameron promises Britons straight choice on EU exit

LONDON (Reuters) - Prime Minister David Cameron promised on Wednesday to give Britons a referendum choice on whether to stay in the European Union or leave if he wins an election in 2015, placing a question mark over Britain's membership for years.

Cameron ended months of speculation by announcing in a speech the plan for a vote sometime between 2015 and the end of 2017, shrugging off warnings that this could imperil Britain's economic prospects and alienate its biggest trading partner.

He said Britain, a member of the European Economic Community for 40 years, did not want to retreat from the world but that the island nation's public disillusionment with the EU was at "an all-time high".

"It is time for the British people to have their say. It is time for us to settle this question about Britain and Europe," Cameron said. His Conservative party will campaign for the 2015 election promising to renegotiate Britain's EU membership.

"When we have negotiated that new settlement, we will give the British people a referendum with a very simple in or out choice to stay in the European Union on these new terms; or come out altogether. It will be an in-out referendum."

The speech firmly ties Cameron to an issue that was the bane of a generation of Conservative leaders. In the past, he has tried to avoid partisan fights over Europe, the undoing of the last two Conservative prime ministers, John Major and Margaret Thatcher.

Britain would seek to claw back powers from Brussels, he said, a proposal that will be difficult to sell to other European countries. London will do an "audit" to determine which powers Brussels has that should be delegated to member states.

Sterling fell to its lowest in nearly five months against the dollar on Wednesday as Cameron was speaking.

The response from EU partners was predictably frosty. French Foreign Minister Laurent Fabius quipped: "If Britain wants to leave Europe we will roll out the red carpet for you," echoing Cameron himself, who once used the same words to invite rich Frenchmen alienated by high taxes to move to Britain.

German Foreign Minister Guido Westerwelle said his country wanted Britain to remain a full EU member, but London could not expect to pick and choose the aspects of membership it liked.

Business leaders have warned that the prospect of years of doubt over Britain's EU membership would damage the investment climate.

"Having a referendum creates more uncertainty and we don't need that," Martin Sorrell, chief executive of advertising giant WPP, told the World Economic Forum in Davos.

"This is a political decision. This is not an economic decision. This isn't good news. You added another reason why people will postpone investment decisions."

The speech also opens a rift with Cameron's junior coalition partners, the Liberal Democrats. Their leader, Deputy Prime Minister Nick Clegg, said the plan would undermine a fragile economic recovery.

And even allies further afield are wary: the United States has said it wants Britain to remain inside the EU with "a strong voice".

But Eurosceptics in Cameron's party were thrilled by the speech. Conservative lawmaker Peter Bone called it "a terrific victory" that would unify 98 percent of the party. "He's the first prime minister to say he wants to bring back powers from Brussels," Bone told Reuters. "It's pretty powerful stuff".

Whether Cameron will ever hold the referendum remains as uncertain as the Conservatives' chances of winning the next election in 2015.

They trail the opposition Labour party in opinion polls, and the coalition government is grappling with a stagnating economy as it pushes through public spending cuts to reduce Britain's large budget deficit.

Cameron said he would prefer Britain, the world's sixth biggest economy, to remain inside the 27-nation EU. As long as he secured the reforms he wants, he would campaign for Britain to stay inside the EU "with all my heart and soul".

But he also made clear he believed the EU must be radically reformed. It was riskier to maintain the status quo than to change, he said.

"The biggest danger to the European Union comes not from those who advocate change, but from those who denounce new thinking as heresy," he said.

"WAFER THIN" CONSENT

The euro zone debt crisis was forcing the bloc to change, and Britain would fight to make sure new rules were fair to countries that didn't use the common currency, he said. Britain is the largest of the 10 EU members that do not use the euro.

Democratic consent for the EU in Britain was now "wafer thin", he said, reflecting the results of opinion polls that show a slim majority would vote to leave the bloc and the rise of the UK Independence Party that favors complete withdrawal.

"Some people say that to point this out is irresponsible, creates uncertainty for business and puts a question mark over Britain's place in the European Union," said Cameron. "But the question mark is already there: ignoring it won't make it go away."

Asked after the speech whether other EU countries would agree to renegotiate Britain's membership, Cameron said he was an optimist and that there was "every chance of success."

"I want to be the prime minister who confronts and gets the right answer for Britain on these kind of issues," he said.

It is nearly 40 years since British voters last had a say in a referendum on Britain's membership of the European club. A 1975 vote saw just over 67 percent opt to stay inside with nearly 33 percent wanting to leave.

Jim, John Harbaugh ready for rematch at Super Bowl

SANTA CLARA, Calif. (AP) — Jim and John Harbaugh have exchanged a handful of text messages, and plan to leave it at that. No phone conversations necessary while the season's still going. No time for pleasantries, even for the friendly siblings.

There is work to be done to prepare for the Super Bowl, prepare for each other, prepare for a history-making day already being widely hyped as "Harbowl" or "Superbaugh" depending which nickname you prefer.

"It doesn't matter who the coach is, what relationship you have with the person on the other side," 49ers coach Jim Harbaugh said so matter-of-factly Monday afternoon.

Their parents sure aren't picking sides for the Feb. 3 matchup in New Orleans.

These days, the Harbaughs' longtime coaching father, Jack, stays away from game-planning chatter or strategy sessions with his Super Bowl-bound coaching sons. Baltimore's John Harbaugh and little brother Jim have been doing this long enough now to no longer need dad's input.

Yet, they still regularly seek it. And, their father does offer one basic mantra: "Get ahead, stay ahead."

"Probably the greatest advice that I've ever been given and the only advice that I've ever found to be true in all of coaching, I think we mentioned it to both John and Jim ... the coaching advice is, 'Get ahead, stay ahead,'" Jack Harbaugh said.

"If I'm called upon, I'll repeat that same message."

His boys still call home regularly to check in with the man who turned both on to the coaching profession years ago, and the mother who has handled everything behind the scenes for decades in a highly competitive, sports-crazed family — with all the routine sports clichés to show for it.

The Harbaugh brothers will become the first siblings to square off from opposite sidelines when their teams play for the NFL championship at the Superdome.

Not that they're too keen on playing up the storyline that has no chance of going away as hard as they try.

"Well, I think it's a blessing and a curse," Jim Harbaugh said Monday. "A blessing because that is my brother's team. And, also, personally I played for the Ravens. Great respect for their organization. ... The curse part would be the talk of two brothers playing in the Super Bowl and what that takes away from the players that are in the game. Every moment that you're talking about myself or John, that's less time that the players are going to be talked about."

Both men love history, just not the kind with them making it.

"I like reading a lot of history ... I guess it's pretty neat," John Harbaugh offered Monday. "But is it really going to be written about? It's not exactly like Churchill and Roosevelt or anything. It's pretty cool, but that's as far as it goes."

Nice try, guys.

John watched the end of Jim's game from the field in Foxborough, Mass., as Baltimore warmed up for the AFC championship game. Jim called his sister's family from the team plane before takeoff after a win at Atlanta and asked how his big brother's team was doing against New England.

The improbable Super Bowl features a set of brothers known around the NFL as fierce competitors unafraid to make a bold move during the season. Unafraid to upset anyone who stands in their way.

In fact, each one made a major change midseason to get this far — John fired his offensive coordinator, while Jim boosted his offense with a quarterback switch from Alex Smith to Colin Kaepernick.

Leading up to Sunday's games, parents Jack and Jackie said they would wait to decide whether to travel to New Orleans if both teams advanced or stick to what has been working so well — watching from the comfort of their couch in Mequon, Wis.

"We enjoy it very much. We get down in our basement, turn on the television and just have a fantastic day watching outstanding football," Jack said last week. "We share our misery with no one but ourselves. Not only the misery, but the ups and downs, the ins and outs of an outstanding professional game."

And, no, the Harbaughs weren't looking ahead to a potential big trip to the Big Easy.

Jack insists his wife is quick to pull out that old sports cliche: "It's one game at a time. I think it's very appropriate," he said.

Jim figures they won't possibly miss this history-making game.

"I think they'll be there," he said with a smile.

The brothers, separated in age by 15 months, have taken different paths to football's biggest stage — years after their intense games of knee football at the family home. They tried to beat each other at cards, or whatever other game it was at the time. Sometimes, they tried to beat each other up. Sister, Joani Crean, often got in on the fun, too.

The 49-year-old Jim never reached a Super Bowl, falling a last-gasp pass short during a 15-year NFL career as a quarterback. The 50-year-old John never played in the NFL.

Still, both will tell you, "Who's got it better than us? No-body!" — one catchphrase they got from their dad.

"We can't put into words what it means to see John and Jim achieve this incredible milestone," their brother-in-law, Indiana basketball coach Tom Crean, said on Twitter. "We talked to Jim (before) his team plane left. All he wanted to know was how was John doing? How were they playing? One incredible family who puts the care, well-being and love for each other at the forefront like most families do. Again, we are very proud of them. Going to be exciting to watch it unfold."

John worked his way up from the bottom of the coaching ranks, while Jim was the star college quarterback at Michigan, a first-round draft pick and eventual Pro Bowler who made coaching his career once he retired.

John already has the one-up, while Jim's team is the early favorite. John's Ravens beat the 49ers 16-6 on Thanksgiving night 2011, in Jim's rookie season as an NFL coach — though both know that means nothing now.

"I just want everybody to know, that was a four-day deal and every story has been told," John said. "We're not that interesting. There's nothing more to learn. The tape across the middle of the room story, OK, you got it? It's OK. It was just like any other family, really. I really hope the focus is not so much on that. We get it, it's really cool and it's exciting and all that."

Said Jim, "Completely new business."

In spite of his efforts to avoid the topic, Jim did take the opportunity to express how proud he is of John.

"He's a great football coach, a real grasp of all phases — offense, defense, special teams. I think he could coordinate at least two of those phases and do it as well as anyone in the league," Jim said. "I've got half the amount of coaching experience he does. Again, it's not about us. I keep coming back to that. I'm really proud of my brother. I love him. That's the blessing part, that this is happening to him."

And, fittingly for the big brother, John feels the exact same way.

NASA’s Planet-Hunting Kepler Telescope Stalled by Glitch

NASA’s prolific planet-hunting Kepler space telescope has been placed in a precautionary “safe mode” after engineers noticed a problem with the instrument’s orientation mechanism.

The Kepler telescope went into safe mode on Jan. 17 for a planned 10 days, during which time the telescope’s reaction wheels — spinning devices used by the observatory to maintain its position in space —will be rested. The move comes after researchers detected an unexpected increase in the amount of torque needed to rotate one of the wheels, mission officials said.

“Resting the wheels provides an opportunity to redistribute internal lubricant, potentially returning the friction to normal levels,” Kepler officials wrote in a Jan. 17 mission update.

Kepler will not make any new science observations for its search for alien planets while in safe mode, team members said.

“Once the 10-day rest period ends, the team will recover the spacecraft from this resting safe mode and return to science operations,” Kepler officials wrote. “That is expected to take approximately three days. An update will be posted after the wheel rest operation is complete.” [Gallery: A World of Kepler Planets]

When the Kepler spacecraft launched in March 2009, it had four functional reaction wheels — three for immediate use, plus one spare. The wheels help the telescope keep its precise aim at more than 150,000 target stars, which it monitors for the presence of orbiting exoplanets. 

One of the wheels failed last July. Since the spacecraft needs three functioning reaction wheels to work properly, another failure could potentially end the $ 600 million Kepler mission.

Kepler detects alien planets by flagging the telltale brightness dips caused when they cross the face of their parent stars from the instrument’s perspective. Kepler generally needs to witness three such “transits” to identify a planetary candidate.

The telescope has already spotted more than 2,700 potential planets, including a number in their host stars’ habitable zones — that range of distances that could support liquid water on a world’s surface. To date, just 105 of these candidates have been confirmed, but mission scientists think at least 90 percent should end up being the real deal.

If the three remaining reaction wheels keep spinning normally and Kepler doesn’t suffer any other major issues, it could keep scanning its patch of sky for several more years to come. Last year, NASA announced that it had extended the mission through at least 2016.

Kepler’s main mission is to find Earth-size planets in the habitable zone. The longer it runs, the more such worlds it will find.

Because of the three-transit requirement, most of the planets Kepler has found so far zip around their stars relatively quickly, in close-in orbits.

With more time, the instrument will be able to discover more exoplanets in relatively distant orbits, allowing Kepler to survey the habitable zones of warmer stars. (It could take a hypothetical alien version of Kepler up to three years, after all, to see Earth transit the sun three times.)

Witnessing more transits will also increase the signal-to-noise ratio, enabling more relatively small planets to be detected, researchers have said.

Defterios: What keeps Davos relevant

STORY HIGHLIGHTS

• Since the late 20th Century, the ski resort of Davos has been synonymous with the World Economic Forum


• Defterios: I first came to Davos as a relatively junior correspondent, two months after the Berlin Wall fell


• Fall of Communism, China's opening, removal of apartheid in South Africa unfolded in the 90s
  
  


• It's the inter-play between geo-politics and business is what keeps the forum relevant

Davos (CNN) -- Veterans of Davos often refer to nature's awe-inspiring work as the Magic Mountain.

The name comes from an early 20th century novel by Thomas Mann -- reflecting on life in an alpine health retreat, and the mystery of time in this breath-taking setting.

Since the late 20th century, this ski resort has been synonymous with the World Economic Forum, which represents networking on its grandest scale.

This year nearly 40 world leaders -- a record for this annual meeting -- 2000 plus executives and it seems an equal number of people in the media, like yours truly, are in pursuit of them all. The setting is certainly more chaotic then a decade ago. The agendas of the Fortune 500 chief executives are to filled with bi-lateral meetings and back door briefings to allow for the spontaneity that made this venue unique.

Davos gets ready for leaders' gathering

HIDE CAPTION

I first came to Davos as a relatively junior correspondent in 1990, two months after the fall of the Berlin Wall. It was arguably then, after nearly two decades in the conference business, when the forum became a fixture on the global calendar.

Quest: U.S. economy to dominate Davos 2013

I can remember, quite vividly, working out of a bunker (like we do today) in the Davos Congress Centre. West German Chancellor Helmut Kohl sat side-by-side with his East German counterpart Hans Modrow. That meeting before the global community helped set the stage for monetary union, a huge unification fund for what became Eastern Germany and shortly thereafter German elections.

The early 90s at Davos were dominated by European reconstruction after the fall of communism. Former party bosses came to the forum to convince business leaders that a transition to market economics could be delivered. Boris Yeltsin made his Davos appearance during that chaotic transition from the USSR to today's Russia.

Davos 2013: New year, same old problems?

In 1992, Chinese Premier Li Peng used the setting here in the Alps to articulate plans for the country's economic opening up to the world. Not by chance, the architect of Washington's engagement with Beijing, the former U.S. Secretary of State Henry Kissinger also took a high profile that year.

Again only two years later in 1994, Yasser Arafat and Shimon Peres walked hand in hand on stage, holding a public dialogue leading up to the creation and recognition of the Palestinian Authority.

The World Economic Forum, as the saying goes, was positioned to be in the right place at the right time. While the author of the Magic Mountain talked about the complexity of time around World War I, in the 1990s time was compressed here.

The fall of communism, the lowering of global trade barriers, the opening up of China, the removal of apartheid in South Africa and the proliferation of the internet all unfolded in that decade.

Interactive: How's your economic mood?

As those events came together, so too did the major players as they made the journey to Davos. Michael Bloomberg, evolving as a global name in financial data and now the Mayor of New York City, sat alongside Microsoft CEO Bill Gates. U.S. President Bill Clinton outlined his party's historic move to the political center before a packed audience of global business executives.

To spice things up, rock stars and actors, as they became activists, chose the Davos platform: Bono, Richard Gere, Sharon Stone, Brad and Angelina would have the wealthiest and most powerful corporate titans freeze in their tracks.

Earlier this week, I walked into the main plenary hall as workers put the final touches on the stage and lighting. It is a venue which has welcomed countless political leaders and business executives, during internet booms and banking busts, in the midst of a Middle East crisis and even during the lead up to two Gulf Wars.

But that inter-play between geo-politics and business -- during the best and worst of times -- is what keeps the forum relevant. It allows this setting at the base of the Magic Mountain to endure and recreate something unique during what Mann rightly described as the ongoing complexity of our times.

Body of cyanide-poisoned lottery winner is reburied

Mohammed Zaman on the exhumation of his brother-in-law, poisoned lottery winner Urooj Khan. (Posted on: Jan. 21, 2013.)

The body of a West Rogers Park man who died of cyanide poisoning last summer after winning a million-dollar lottery was laid to rest again Monday, three days after his remains were exhumed for an autopsy as part of a homicide investigation.

The scene at Rosehill Cemetery on Monday afternoon was in sharp contrast to Friday morning, when a throng of reporters and TV cameramen had massed outside an entrance gate as numerous Chicago police, Cook County medical examiner officials and cemetery workers surrounded the gravesite while Urooj Khan's remains were unearthed.

About half a dozen people — two in light blue coveralls — wheeled a gurney carrying Khan's body Monday from the back of an unmarked white minivan to under a tent at his gravesite in the Far North Side cemetery. The body was then lowered into the ground while two of Khan's relatives stood at the gravesite in the bitter cold.

Haroon Firdausi, a funeral director and imam, gave a brief prayer during the reburial.

The entire reburial took about 20 minutes.

Shortly before the reburial, one of Khan's relatives, Mohammed Zaman, talked briefly at the cemetery about the family's discomfort with his body being exhumed for the police investigation.

"The sad part is that he wasn't resting in peace," Zaman said of the exhumation. "... Now we have to bury him back again. For any religion, it's hard."

As the Tribune first revealed earlier this month, the medical examiner's office initially ruled that Khan's death in July was from hardening of the arteries, after no signs of trauma were found on the body and a preliminary blood test did not raise any questions. But the investigation was reopened about a week later after a relative raised concerns that Khan may have been poisoned.

Chicago police were notified in September after tests showed cyanide in Khan's blood. By late November, more comprehensive testing showed lethal levels of the toxic chemical, leading the medical examiner's office to declare the death a homicide.

After Khan's body was exhumed Friday, an autopsy was performed for evidence that could aid in the homicide investigation. At the time, Chief Medical Examiner Stephen Cina said it could take several weeks for the tests to be completed. The medical examiner's office hopes samples taken from Khan's organs will show whether he ingested or inhaled the cyanide.

Although a motive has not been determined, police have not ruled out that Khan was killed because of his lottery win a few weeks before his death, a law enforcement source has told the Tribune. At the time of his death, he hadn't collected his winnings — a lump-sum payment of about $425,000 after taxes.

Zaman said he hopes the autopsy sheds more light on his brother-in-law's death.

"It's very hard for the family," Zaman said of the exhumation and reburial. "But it's the only way to find out what happened to him."

Israel goes to polls, set to re-elect Netanyahu

JERUSALEM (Reuters) - Israelis voted on Tuesday in an election that is expected to see Prime Minister Benjamin Netanyahu win a third term in office, pushing the Jewish state further to the right, away from peace with the Palestinians and towards a showdown with Iran.

However, Netanyahu's own Likud party, running alongside the ultra-nationalist Yisrael Beitenu group, looks set to have fewer seats than in the previous parliament, with opinion polls showing a surge in support for the far-right Jewish Home party.

Political sources said Netanyahu, concerned by his apparent fall in popularity, might approach centre-left parties after the vote in an effort to broaden his coalition and present a more moderate face to Washington and other concerned allies.

"We want Israel to succeed, we vote Likud-Beitenu ... The bigger it is, the more Israel will succeed," Netanyahu said after casting his ballot alongside his wife and two sons.

Some 5.66 million Israelis are eligible to vote, with polling stations closing at 10 p.m. (2000 GMT). Full results are due by Wednesday morning, opening the way for coalition talks that could take several weeks.

The lackluster election campaign failed to focus on any single issue and with a Netanyahu victory predicted by every opinion poll, the two main political blocs seemed to spend more time on internal feuding than confronting each other.

"There is a king sitting on the throne in Israel and I wanted to dethrone him, but it looks like that won't happen," said Yehudit Shimshi, a retired teacher voting in central Israel, on a bright, hot mid-winter morning.

No Israeli party has ever secured an absolute majority, meaning that Netanyahu, who says that dealing with Iran's nuclear ambitions is his top priority, will have to bring various allies onboard to control the 120-seat Knesset.

The former commando has traditionally looked to religious, conservative parties for backing and is widely expected to seek out the surprise star of the campaign, self-made millionaire Naftali Bennett who heads the Jewish Home party.

Bennett has ruled out any peace pact with the Palestinians and calls for the annexation of much of the occupied West Bank.

His youthful dynamism has struck a chord amongst Israelis, most of whom no longer believe in the possibility of a Palestinian deal, and has eroded Netanyahu's support base.

The Likud has also shifted further right in recent months, with hardline candidates who reject the so-called two-state solution, dominating the top of the party list.

"TRENDY PARTIES"

Surveys suggest Bennett may take up to 14 seats, many at the expense of Likud-Beitenu, which was projected to win 32 in the last round of opinion polls published on Friday -- 10 less than the two parties won in 2009 when they ran separate lists.

Acknowledging the threat, Netanyahu's son Yair urged young Israelis not to abandon the old, established Likud.

"Even if there are more trendy parties, there is one party that has a proven record," he said on Tuesday.

Amongst the new parties standing for the first time in an election were Yesh Atid (There is a Future), a centrist group led by former television host Yair Lapid, seen winning 13 seats.

"All our lives we voted Likud, but today we voted for Lapid because we want a different coalition," said Ahuva Heled, 55, a retired teacher voting with her husband north of Tel Aviv.

Lapid has not ruled out joining a Netanyahu cabinet, but is pushing hard for ultra-Orthodox Jews to do military service -- a demand fiercely rejected by some allies of the prime minister.

Israel's main opposition party, Labour, which is seen capturing up to 17 seats, has already ruled out a repeat of 2009, when it initially hooked up with Netanyahu, promising to promote peace negotiations with the Palestinians.

U.S.-brokered talks collapsed just a month after they started in 2010 following a row over settlement building, and have laid in ruins ever since. Netanyahu blamed the Palestinians for the failure and says his door remains open to discussions.

Palestinian President Mahmoud Abbas says he won't return to the table unless there is a halt to settlement construction.

That looks unlikely, with Netanyahu approving some 11,000 settler homes in December alone, causing further strains to his already notoriously difficult relations with U.S. President Barack Obama, who was sworn in for a second term on Monday.

IRAN THREAT

Tuesday's vote is the first in Israel since Arab uprisings swept the region two years ago, reshaping the Middle East.

Netanyahu has said the turbulence - which has brought Islamist governments to power in several countries long ruled by secularist autocrats, including neighboring Egypt - shows the importance of strengthening national security.

If he wins on Tuesday, he will seek to put Iran back to the top of the global agenda. Netanyahu has said he will not let Tehran enrich enough uranium to make a single nuclear bomb - a threshold Israeli experts say could arrive as early as mid-2013.

Iran denies it is planning to build the bomb, and says Israel, widely believed to have the only nuclear arsenal in the Middle East, is the biggest threat to the region.

The issue has barely registered during the election campaign, with a poll in Haaretz newspaper on Friday saying 47 percent of Israelis thought social and economic issues were the most pressing concern, against just 10 percent who cited Iran.

One of the first problems to face the next government, which is unlikely to take power before the middle of next month at the earliest, is the stuttering economy.

Data last week showed the budget deficit rose to 4.2 percent of gross domestic product in 2012, double the original estimate, meaning spending cuts and tax hikes look certain.
