Deformed Dolphin Accepted Into New Family

In 2011, behavioral ecologists Alexander Wilson and Jens Krause of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Germany were surprised to discover that a group of sperm whales (Physeter macrocephalus)—animals not usually known for forging bonds with other species—had taken in an adult bottlenose dolphin (Tursiops truncatus).

The researchers observed the group in the ocean surrounding the Azores (map)—about 1,000 miles (1,600 kilometers) off the coast of Lisbon, Portugal—for eight days as the dolphin traveled, foraged, and played with both the adult whales and their calves. When the dolphin rubbed its body against the whales, they would sometimes return the gesture.

Among terrestrial animals, cross-species interactions are not uncommon. These mostly temporary alliances are forged for foraging benefits and protection against predators, said Wilson.

They could also be satisfying a desire for the company of other animals, added marine biologist John Francis, vice president for research, conservation, and exploration at the National Geographic Society (the Society owns National Geographic news).

Photographs of dogs nursing tiger cubs, stories of a signing gorilla adopting a pet cat, and videos of a leopard caring for a baby baboon have long circulated the web and caught national attention.

A Rare Alliance

And although dolphins are known for being sociable animals, Wilson called the alliance between sperm whale and bottlenose dolphin rare, as it has never, to his knowledge, been witnessed before.

This association may have started with something called bow riding, a common behavior among dolphins during which they ride the pressure waves generated by the bow of a ship or, in this case, whales, suggested Francis.

"Hanging around slower creatures to catch a ride might have been the first advantage [of such behavior]," he said, adding that this may have also started out as simply a playful encounter.

Wilson suggested that the dolphin's peculiar spinal shape made it more likely to initiate an interaction with the large and slow-moving whales. "Perhaps it could not keep up with or was picked on by other members of its dolphin group," he said in an email.

Default

But the "million-dollar question," as Wilson puts it, is why the whales accepted the lone dolphin. Among several theories presented in an upcoming paper in Aquatic Mammals describing the scientists' observations, they propose that the dolphin may have been regarded as nonthreatening and that it was accepted by default because of the way adult sperm whales "babysit" their calves.

Sperm whales alternate their dives between group members, always leaving one adult near the surface to watch the juveniles. "What is likely is that the presence of the calves—which cannot dive very deep or for very long—allowed the dolphin to maintain contact with the group," Wilson said.

Wilson doesn't believe the dolphin approached the sperm whales for help in protecting itself from predators, since there aren't many dolphin predators in the waters surrounding the Azores.

But Francis was not so quick to discount the idea. "I don't buy that there is no predator in the lifelong experience of the whales and dolphins frequenting the Azores," he said.

He suggested that it could be just as possible that the sperm whales accepted the dolphin for added protection against their own predators, like the killer whale (Orcinus orca), while traveling. "They see killer whales off the Azores, and while they may not be around regularly, it does not take a lot of encounters to make [other] whales defensive," he said.

Pentagon to Allow Women in Combat

Defense Secretary Leon Panetta will lift a longstanding ban on women serving in combat, according to senior defense officials.

The services have until this May to come up with a plan to implement the change, according to a Defense Department official.

That means the changes could come into effect as early as May, though the services will have until January 2016 to complete the implementation of the changes.

"We certainly want to see this executed responsibly but in a reasonable time frame, so I would hope that this doesn't get dragged out," said former Marine Capt. Zoe Bedell, who joined a recent lawsuit aimed at getting women on the battlefield.

The military services also will have until January 2016 to seek waivers for certain jobs -- but those waivers will require a personal approval from the secretary of defense and will have to be based on rationales other than the direct combat exclusion rule.

The move to allow women in combat, first reported by the Associated Press, was not expected this week, although there has been a concerted effort by the Obama administration to further open up the armed forces to women.

The Joint Chiefs of Staff unanimously recommended in January to Secretary Panetta that the direct combat exclusion rule should be lifted.

"I can confirm media reports that the secretary and the chairman are expected to announce the lifting of the direct combat exclusion rule for women in the military," said a senior Defense Department official. "This policy change will initiate a process whereby the services will develop plans to implement this decision, which was made by the secretary of defense upon the recommendation of the Joint Chiefs of Staff."

Chairman of the Joint Chiefs Gen. Martin Dempsey sent Panetta a memo earlier this month entitled, "Women in Service Implementation Plan."

"The time has come to rescind the direct combat exclusion rule for women and to eliminate all unnecessary gender-based barriers to service," the memo read.

"To implement these initiatives successfully and without sacrificing our warfighting capability or the trust of the American people, we will need time to get it right," he said in the memo, referring to the 2016 horizon.

Women have been officially prohibited from serving in combat since a 1994 rule that barred them from serving in ground combat units. That does not mean they have been immune from danger or from combat.

As Martha Raddatz reported in 2009, women have served in support positions on and off the frontlines in Iraq and Afghanistan, where war is waged on street corners and in markets, putting them at equal risk. Hundreds of thousands of women deployed with the military to those two war zones over the past decade. Hundreds have died.

"The reality of the battlefield has changed really since the Vietnam era to where it is today," said Rep. Tammy Duckworth, D-Ill., a former military helicopter pilot who lost both her legs in combat. "Those distinctions on what is combat and what is not really are falling aside. So I think that after having seen women, men, folks who -- cooks, clerks, truck drivers -- serve in combat conditions, the reality is women are already in combat."

Woman have been able to fly combat sorties since 1993. In 2010, the Navy allowed them on submarines. But lifting restrictions on service in frontline ground combat units will break a key barrier in the military.

Panetta's decision will set a January 2016 deadline for the military service branches to argue that there are military roles that should remain closed to women.

In February 2012 the Defense Department opened up 14,500 positions to women that had previously been limited to men and lifted a rule that prohibited women from living with combat units.

Panetta also directed the services to examine ways to open more combat roles to women.

However, the ban on direct combat positions has remained in place.

Malaysia citizenship-for-votes probe stirs outrage

KUALA LUMPUR: For years, charges have swirled that a secret Malaysian scheme gave citizenship to huge numbers of illegal migrants in a politically important state in exchange for votes for the ruling coalition.

Now, an inquiry is finally airing detailed allegations that have the government on the defensive ahead of elections that pose the greatest threat yet faced by the ruling bloc that has controlled Malaysia for 56 years.

A Royal Commission of Inquiry opened last week with ex-officials admitting they gave citizenship to Filipinos and Indonesians in resource-rich Sabah, one of two Malaysian states on Borneo island.

One former official said some 100,000 identity cards (ICs) were handed out in 1993 ahead of a crucial state election, Malaysian news reports said. Another admitted signing hundreds of thousands of ICs in the 1990s.

The testimony has revived accusations of treason against former prime minister Mahathir Mohamad, who is alleged to have masterminded the scheme to shore up support for his government.

As head of the ruling Barisan Nasional (BN) coalition, Mahathir dominated Malaysia for 22 years until he resigned in 2003.

Current prime minister Najib Razak is now battling to rally support for the BN ahead of polls he is expected to call within months, in an era when the coalition's power grip has slipped.

But outrage over "Project IC", as the alleged scheme is widely known, is undercutting his claims that the national electoral roll is free of fraud.

The opposition and election-reform advocates allege massive fraud in voter rolls nationwide and have seized on the testimony as proof of government vote-tampering.

"What we are concerned about is that this is still going on. That's what we want to stop," Ambiga Sreenevasan, head of the clean-elections activist coalition known as "Bersih", or "Clean", told a press conference on Tuesday.

The outlines of "Project IC" have been whispered about for three decades and have bolstered the view of Sabah as a reliable "fixed deposit" of votes for the BN to help it weather challenges elsewhere.

The government allegedly targeted Muslims from neighbouring Indonesia and the predominantly Muslim southern Philippines.

More than half of Malaysia's 29 million people are Muslim ethnic Malays, but indigenous tribes, many of them Christian, predominate in Sabah.

They have bridled at the foreigners, blaming them for crime, drug abuse and economic competition, and alleging their homeland was being stolen.

Najib last June gave in to calls for an inquiry, but the move could backfire, said Ibrahim Suffian, head of independent polling firm Merdeka Centre, calling the revelations "explosive".

"It probably will create a wave of resentment and dissatisfaction among native Sabah voters. This confirms their worst fears," he said.

The population of Sabah, a region of rugged mountains and powerful rainforest rivers that is about the size of Ireland, has surged from some 600,000 citizens in 1970 to more than three million -- more than double the national growth rate.

Malaysia's opposition alleges some 700,000 may have illegally received ICs. A one-time battleground state, Sabah has been pro-BN since the mid-1990s.

The once all-powerful BN suffered a shock setback in 2008 national elections, and analysts predict a close fight with a formidable opposition led by Anwar Ibrahim, a former deputy premier, raising fears that government fraud could play a role.

Najib insists the national electoral system is clean and has highlighted recent reforms such as plans to use indelible ink to prevent multiple voting.

"Let the commission do its work and find out," Najib was quoted as saying by state media, warning against a rush to judgement in Sabah.

Mahathir, still a vocal and influential conservative figure, has denied the existence of "Project IC," but admitted at a press conference last week that foreigners in Sabah were given citizenship, saying no laws were broken.

No one has yet directly implicated him before the commission, but witnesses said last week they were directed by officials close to Mahathir. There has been no testimony yet suggesting "Project IC" was still active.

Hearings will continue for weeks, with some 170 witnesses expected to testify. The commission has until late March to investigate.

The commission's final recommendations are not legally binding, but could lead to pressure for a crackdown on illegals.

BJP to hold countrywide protests against Shinde's remarks

NEW DELHI: The BJP will hold countrywide protests from Thursday against home minister Sushilkumar Shinde's "Hindu terror" remarks, Rajnath Singh said after being elected as the party president on Wednesday.

"The recent statement of Shinde shows the government is not serious on its fight against terrorism," Rajnath Singh said, addressing party workers here.

"Just for vote bank politics, they are poisoning the atmosphere of the nation with communalism. We condemn the statement," he said.

He said the Bharatiya Janata Party (BJP) would hold countrywide protests against Shinde's comments.

The Promise and Perils of Mining Asteroids

Encouraged by new space technologies, a growing fleet of commercial rockets and the vast potential to generate riches, a group of entrepreneurs announced Tuesday that they planned to mine the thousands of near-Earth asteroids in the coming decades.

The new company, Deep Space Industries (DSI), is not the first in the field, nor is it the most well-financed. But with their ambition to become the first asteroid prospectors, and ultimately miners and manufacturers, they are aggressively going after what Mark Sonter, a member of DSI's board of directors, called "the main resource opportunity of the 21st century." (Related: "Asteroid Hunter to Be First Private Deep-Space Mission?")

Prospecting using miniaturized "cubesat" probes the size of a laptop will begin by 2015, company executives announced. They plan to return collections of asteroid samples to Earth not long after.

"Using low cost technologies, and combining the legacy of [the United States'] space program with the innovation of today's young high tech geniuses, we will do things that would have been impossible just a few years ago," said Rick Tumlinson, company chairman and a longtime visionary and organizer in the world of commercial space [not sure what commercial space means].

"We sit in a sea of resources so infinite they're impossible to describe," Tumlinson said.

Added Value

There are some 9,000 asteroids described as "near-Earth," and they contain several classes of resources that entrepreneurs are now eyeing as economically valuable.

Elements such as gold and platinum can be found on some asteroids. But water, silicon, nickel, and iron are the elements expected to become central to a space "economy" should it ever develop.

Water can be "mined" for its hydrogen (a fuel) and oxygen (needed for humans in space), while silicon can be used for solar power systems, and the ubiquitous nickel and iron for potential space manufacturing. (See an interactive on asteroid mining.)

Sonter, an Australian mining consultant and asteroid specialist, said that 700 to 800 near-Earth asteroids are easier to reach and land on than the moon.

DSI's prospecting spacecraft will be called "FireFlies," a reference to the popular science fiction television series of the same name. The FireFlies will hitchhike on rockets carrying up communication satellites or scientific instruments, but they will be designed so that they also have their own propulsion systems. The larger mining spacecraft to follow have been named "DragonFlies."

Efficiencies

It all sounds like science fiction, but CEO David Gump said that the technology is evolving so quickly that a space economy can soon become a reality. Providing resources from beyond Earth to power spacecraft and keep space travelers alive is the logical way to go.

That's because the most expensive and resource-intensive aspect of space travel is pushing through the Earth's atmosphere. Some 90 percent of the weight lifted by a rocket sending a capsule to Mars is fuel. Speaking during a press conference at the Santa Monica Museum of Flying in California, Gump said that Mars exploration would be much cheaper, and more efficient, if some of the fuel could be picked up en route. (Related: "7 Ways You Could Blast Off by 2023.")

Although there is little competition in the asteroid mining field so far, DSI has some large hurdles ahead of it. The first company to announce plans for asteroid mining was Planetary Resources, Inc. in spring 2012—the group is backed by big-name investors such as Google's Larry Page and Eric Schmidt, filmmaker James Cameron, and early Google investor Ram Shriram. DSI is still looking for funding.

Owning Asteroids

While these potential space entrepreneurs are confident they can physically lay claim to resources beyond Earth, there remain untested legal issues.

The United Nations Space Treaty of 1967 expressly forbids ownership of other celestial bodies by governments on Earth. But American administrations have long argued that the same is not true of private companies and potential mining rights.

While an American court has ruled that an individual cannot own an asteroid—as in the case of Gregory Nemitz, who laid claim to 433 Eros as a NASA spacecraft was approaching it in 2001—the question of extraction rights has not been tested.

Moon rocks brought back to Earth during the Apollo program are considered to belong to the United States, and the Russian space agency has sold some moon samples it has returned to Earth-sales seen by some as setting a precedent.

Despite the potential for future legal issues, DSI's Gump said his group recently met with top NASA officials to discuss issues regarding technology and capital, and came away optimistic. "There's a great hunger for the idea of getting space missions done with smaller, cheaper 'cubesat' technology and for increased private sector involvement."

Everyone involved acknowledged the vast challenges and risks ahead, but they see an equally vast potential—both financial and societal.

"Over the decades, we believe these efforts will help expand the civilization of Earth into the cosmos, and change what it means to be a citizen of this planet," Tumlinson said.

Al Qaeda Commander Killed for the 3rd Time

The second in command of al Qaeda's Yemen affiliate was reportedly killed in an airstrike in Yemen in December, according to a news report by Arabic television network Al Arabiya, the third time the former Guantanamo detainee has been reported dead since 2010.

According to the report, Said al-Shihri died last month after sustaining severe injuries from a joint U.S.-Yemeni airstrike that targeted a convoy in which he was riding. The al Arabiya account, based on information from "family sources," said that the airstrike left al-Shihri in a coma. He allegedly died soon after and was buried in Yemen.

On Tuesday afternoon, hours after the initial report, a Yemeni government official denied having any information regarding the death of al-Shihri, according to Arabic news site al-Bawaba.

No photos of a body have yet surfaced and no mention of his death has appeared on jihadi forums.
This is the third time al-Shihri, the second in command of al Qaeda in the Arabian Peninsula (AQAP), has been reported killed since 2009. In 2010, the Yemeni government claimed it had captured him. In September 2012, Yemeni news sites reported he was killed in an American drone strike.

Al-Shihri, a "veteran jihadist," traveled to Afghanistan shortly after the Sept. 11, 2001 terror attacks to fight coalition troops, only to be captured weeks later, according to West Point's Combating Terrorism Center. He was sent to the U.S. prison in Guantanamo Bay, Cuba, where he stayed for six years before being released to Saudi Arabia. There, he entered a so-called "jihadi rehab" program that attempted to turn terrorists into art students by getting them to get "negative energy out on paper," as the program's director told ABC News in 2009.

But just months after he supposedly entered the fingerpainting camp, al-Shihri reappeared in Yemen where he was suspected to have been behind a deadly bombing at the U.S. embassy there.

At the time, critics of the "jihadi rehab" program used al-Shihri as evidence that extremists would just go through the motions in order to be freed.

At second inauguration, Obama relishes the rituals, as well as the smaller moments

The second time seemed to charm him.

The choreography of President Obama’s ceremonial inauguration Monday was nearly identical to that of his swearing-in four years ago: church, motorcade to the Capitol, invocation, oath, address, luncheon, parade, dancing.

This time, however, the man taking the oath of office was an experienced president, not a first-term senator. And Obama seemed determined to relish the rituals and have himself some fun.

In his public remarks, he spoke with conviction. From the Capitol steps, he asserted his intention to bind the nation closer together. He was sober in addressing members of Congress at a luncheon.

But the president also found joy in the smaller moments. He blew kisses as he walked the parade route with his jubilant wife, Michelle, beside him. He bobbed his head and grooved watching a drill group from Iowa pass by and waved the shaka sign to the marching band from his Hawaiian high school alma mater. On the dance floor later, he nuzzled his wife’s hair and crooned in her ear.

There was a majesty and gravity to Monday’s proceedings, but this time, unlike four years ago, Obama knows what his office demands, as well as the limits on its power. His life is not in transition like it was then. He is settled.

He seemed to recognize that the next time the country pauses to inaugurate a president, the Obamas will be moving out of the White House, departing the city by helicopter and heading home. After the ceremony on the Capitol steps, as the president headed inside, he turned back and stopped.

“I want to take a look, one more time,” Obama said. “I’m not going to see this again.”

He stood still and looked out at the panorama of flags waving and people, hundreds of thousands of them, cramming the Mall and chanting his name.

It was as if he wanted to engrave the picture on his mind.

And he seemed to savor such moments throughout the day.

When the Brooklyn Tabernacle Choir sang “The Battle Hymn of the Republic,” he turned and broadly winked at his daughters, Malia, 14, and Sasha, 11.

Myrlie Evers-Williams, a civil rights activist whose husband, Medgar Evers, was assassinated in 1963 in his Mississippi driveway, delivered the invocation. She spoke of being challenged by adversity — “For every mountain, you gave us the strength to climb,” she said — and Obama, his eyes closed in prayer, lifted his shoulders and took a deep breath.

“Amen,” he said at the end of her prayer.

A man behind the president shouted, “Hallelujah!”

When Chief Justice John G. Roberts Jr. delivered the president’s oath at 11:50 a.m., Obama flubbed a word, “the office of president of the United Sta—.” But it didn’t matter. He had recited the official oath correctly a day earlier, on Jan. 20, the inauguration date mandated by the Constitution. (His daughter Sasha already had congratulated him, too: “You didn’t mess up,” she told him in the Blue Room. )

Then, once Sen. Charles E. Schumer (D-N.Y.) introduced him as “the 44th president of the United States,” Obama looked down and smiled. He gathered himself and pushed his chin up, understanding his role in addressing the nation far more clearly than he could have the first time around.

Wen urges "healthy" devt as China's economy slows

BEIJING: Chinese Premier Wen Jiabao has urged the central bank to promote "healthy" economic development, the government said, after the economy expanded at its slowest pace for 13 years in 2012.

Speaking on a visit to the headquarters of the People's Bank of China, Wen called on the central bank to push financial reform and use monetary policy to support the economy, the government said in a statement late on Monday.

"Financial work is still facing a severe and complicated domestic and overseas environment," Wen was quoted as saying.

"We must make full use of monetary policy for the economy to realise continued healthy development," he said, adding prices should be kept stable.

China's economy, the world's second largest, expanded 7.8 percent last year, the government announced on Friday, in the face of weakness at home and in key overseas markets.

The central bank last cut interest rates in July last year, and has instead used its open market operations to boost liquidity to support the economy as growth flagged in the second half.

Last week, the central bank said it would start carrying out short-term operations to manage liquidity in the money market, which analysts say will give policy-makers more flexibility.

Wen called for more financial reforms, including the long-held goals of further liberalising interest rates and making China's yuan currency freely convertible, but gave no details of such moves.

In June last year, the central bank gave banks more flexibility to set interest rates, effectively introducing greater competition and improving allocation of capital.

China last year also began allowing its tightly-controlled currency to trade in a wider band against the US dollar, on the long march for the yuan to become freely convertible.

But Wen also called for preserving financial stability, suggesting future reforms will continue to be incremental.

Wen is set to step down as premier in March, wrapping up a decade overseeing the government and economy.

Li Keqiang, a member of the ruling Communist Party's powerful Politburo Standing Committee, is touted to replace him amid hopes the new leadership might be more aggressive in promoting economic reforms.

Haryana CM appeals for peace after Chautala ruling

NEW DELHI: Haryana chief minister Bhupinder Singh Hooda appealed for peace on Tuesday as supporters of former chief minister Om Prakash Chautala staged violent protests over the 10-year jail sentence given to him and his son in a corruption case.

"All are equal for court, and we have faith in the judiciary. We will appeal to the people to maintain peace, Haryana is a peaceful state," Hooda, who is presently in Delhi, told reporters after the Central Bureau of Investigation (CBI) court in Rohini gave its ruling on the teachers' recruitment scam.

"There are legal processes, if anyone has objection they can follow legal procedures," he added.

Over 600 supporters of Indian National Lok Dal (INLD) chief Chautala and his legislator son Ajay gathered outside the court in Rohini and tried to enter the premises of the court. Delhi Police fired teargas shells, used batons and water cannons to disperse them.

INLD legislator Col. Bir Singh said the central government had manipulated the CBI and Chautala was innocent.

"Several former CBI directors have accepted that CBI works under the pressure of central government. The case of bribery has not been proved here... it is only recruitment of teachers, and none of them have been fired from their job so far," he said.

"We will go to the high court and, if needed, the Supreme Court," he said.

"The supporters are peace loving. Delhi Police resorted to lathi-charge and we condemn it," he said.

Haryana Janhit Congress leader Kuldip Bishnoi welcomed the court decision.

"I welcome the decision of the court. There is no future for INLD in Haryana now. This judgment will not only have an impact on Haryana but all over the country," he said.

He also ruled out the Chautala family getting any sympathy from the people.

"There will be no sympathy factor. What kind of sympathy will they get? They are going to jail for corruption," he said.

Chautala and others were convicted for bribery and tampering with lists to accommodate their favourites and those who had paid money to get recruited as teachers in Haryana's government schools. The recruitment was done for over 3,200 teachers in 1999-2000, when Chautala was chief minister.

Attack at Algeria Gas Plant Heralds New Risks for Energy Development

The siege by Islamic militants at a remote Sahara desert natural gas plant in Algeria this week signaled heightened dangers in the region for international oil companies, at a time when they have been expanding operations in Africa as one of the world's last energy frontiers. (See related story: "Pictures: Four New Offshore Drilling Frontiers.")

As BP, Norway's Statoil, Italy's Eni, and other companies evacuated personnel from Algeria, it was not immediately clear how widely the peril would spread in the wake of the hostage-taking at the sprawling In Amenas gas complex near the Libyan border.

Map by National Geographic

Algeria, the fourth-largest crude oil producer on the continent and a major exporter of natural gas and refined fuels, may not have been viewed as the most hospitable climate for foreign energy companies, but that was due to unfavorable financial terms, bureaucracy, and corruption. The energy facilities themselves appeared to be safe, with multiple layers of security provided both by the companies and by government forces, several experts said. (See related photos: "Oil States: Are They Stable? Why It Matters.")

"It is particularly striking not only because it hasn't happened before, but because it happened in Algeria, one of the stronger states in the region," says Hanan Amin-Salem, a senior manager at the industry consulting firm PFC Energy, who specializes in country risk. She noted that in the long civil war that gripped the country throughout the 1990s, there had never been an attack on Algeria's energy complex. But now, hazard has spread from weak surrounding states, as the assault on In Amenas was carried out in an apparent retaliation for a move by French forces against the Islamists who had taken over Timbuktu and other towns in neighboring Mali. (See related story: "Timbuktu Falls.")

"What you're really seeing is an intensification of the fundamental problem of weak states, and empowerment of heavily armed groups that are really well motivated and want to pursue a set of aims," said Amin-Salem. In PFC Energy's view, she says, risk has increased in Mauritania, Chad, and Niger—indeed, throughout Sahel, the belt that bisects North Africa, separating the Sahara in the north from the tropical forests further south.

On Thursday, the London-based corporate consulting firm Exclusive Analysis, which was recently acquired by the global consultancy IHS, sent an alert to clients warning that oil and gas facilities near the Libyan and Mauritanian borders and in Mauritania's Hodh Ech Chargui province were at "high risk" of attack by jihadis.

"A Hot Place to Drill"

The attack at In Amenas comes at a time of unprecedented growth for the oil industry in Africa. (See related gallery: "Pictures: The Year's Most Overlooked Energy Stories.") Forecasters expect that oil output throughout Africa will double by 2025, says Amy Myers Jaffe, executive director of the energy and sustainability program at the University of California, Davis, who has counted 20 rounds of bidding for new exploration at sites in Africa's six largest oil-producing states.

Oil and natural gas are a large part of the Algerian economy, accounting for 60 percent of government budget revenues, more than a third of GDP and more than 97 percent of its export earnings. But the nation's resources are seen as largely undeveloped, and Algeria has tried to attract new investment. Over the past year, the government has sought to reform the law to boost foreign companies' interests in their investments, although those efforts have foundered.

Technology has been one of the factors driving the opening up of Africa to deeper energy exploration. Offshore and deepwater drilling success in the Gulf of Mexico and Brazil led to prospecting now under way offshore in Ghana, Mozambique, and elsewhere. (See related story: "New Oil—And a Huge Challenge—for Ghana.") Jaffe says the Houston-based company Anadarko Petroleum has sought to transfer its success in "subsalt seismic" exploration technology, surveying reserves hidden beneath the hard salt layer at the bottom of the sea, to the equally challenging seismic exploration beneath the sands of the Sahara in Algeria, where it now has three oil and gas operations.

Africa also is seen as one of the few remaining oil-rich regions of the world where foreign oil companies can obtain production-sharing agreements with governments, contracts that allow them a share of the revenue from the barrels they produce, instead of more limited service contracts for work performed.

"You now have the technology to tap the resources more effectively, and the fiscal terms are going to be more attractive than elsewhere—you put these things together and it's been a hot place to drill," says Jaffe, who doesn't see the energy industry's interest in Africa waning, despite the increased terrorism risk. "What I think will happen in some of these countries is that the companies are going to reveal new securities systems and procedures they have to keep workers safe," she says. "I don't think they will abandon these countries."
