Looking North: Investigating Technology Innovation & Entrepreneurship in North Africa

Much of our focus in the past has centered around Sub-Saharan Africa and in particularly key ?hubs? in the region ? Nigeria in Western Africa, Kenya in Eastern Africa and South Africa in Southern Africa.

However, it goes without saying that though these areas are much discussed and have received a lot of attention for their progress in terms of tech and innovation, there are other countries that deserve to be highlighted on. In future, we?re aiming at canvassing more of the continent and investigating other countries that normally do not pop up by default when hear about ?tech in Africa?.

For example, at the recently concluded DEMO Africa event, I had a chat with Jon Gosier, founder of Appfrica who enlightened me on some of their efforts around the continent. Part of their activities involve running an annual developer contest (Apps4Africa), as part of this they hold developer events in several nations across Africa, I was amazed to learn that some of their highest turnouts were in countries that do not feature in hyped up conversations about tech in Africa.

In this article, I?d like to turn our attention to the northern part of Africa, a region that has received wide attention particularly following the Arab Spring ? but what does the technology innovation and entrepreneurship landscape look like in Northern Africa? We can consider the cases of Egypt and Tunisia:

Basic statistics

The following data is based on indicators published by the Egyptian Ministry of ICT (MICT), specifically the March 2012 ICT Indicators Bulletin and August 2012 ICT Indicators in Brief

Telecommunications & Mobile: In July 2011, Egypt recorded 77.76 million mobile subscriptions, that number jumped to 92.64 million in July 2012, recording an annual growth rate of approximately 19%.

Internet, Web & Social: In July 2011 there were 26.54 million internet users in Egypt of whom 9.95 million were mobile internet users (37.49%), as at July 2012 this number stood at 31.03% (approx. 17% increase) of whom 10.87 million were mobile internet users. The internet penetration rising from 32.96% to 27.79% in the respective periods.

A year after lavish funeral, Savile myth in ruins

LONDON (AP) ? At Jimmy Savile's funeral, a year ago Friday, the priest delivering the homily was emphatic: the DJ and television host "can face eternal life with confidence."

Hundreds of people packed a cathedral for Savile's funeral Mass, thousands paid their respects at his coffin, and people from Prince Charles to the Bee Gees sent condolences. He was a cultural fixture, even an icon, and his BBC television shows had been part of childhood for two generations of Britons.

But a year on, Savile's reputation is in ruins. Police have branded him one of Britain's worst sex offenders, accused of assaulting underage girls over half a century. Like those who feted and praised him on that November day, millions are wondering: How could he have duped so many for so long?

A SELF-MADE MYTH

"His life story was an epic of giving ? giving of time, giving of talent, giving of treasure," Monsignor Kieran Heskin told hundreds of mourners at the funeral. "Sir Jimmy Savile can face eternal life with confidence."

Savile's death, like his life, was full of self-spun mythology. He cast himself as a colorful entertainer who worked tirelessly for charity ? and he choreographed his exit as carefully as an Egyptian pharaoh, leaving instructions for an elaborate three-day commemoration in his home city of Leeds, in northern England.

Thousands of people turned out to pay tribute at the Queen's Hotel, where the entertainer's coffin sat surrounded by flowers, photos and the last cigar he ever smoked. Inside lay Savile, dressed in a tracksuit and clutching a string of rosary beads.

Others lined the street as Savile was carried into St. Anne's Cathedral by Royal Marine pallbearers for a richly ceremonial requiem Mass. Later he was buried in a golden coffin, in a tree-shaded cemetery ? and on a 45-degree angle so he could overlook the sea.

CHARITY SHIELD

"He had gold, jewelry and diamonds, but wealth meant nothing to him," Alistair Hall, a cardiologist at one of the hospitals Savile supported, said in his eulogy. Savile, he said, "was as he appeared ? a caring man."

Savile cultivated the persona of an eccentric, curmudgeonly but generous uncle. He wore brightly colored tracksuits and chunky gold chains and drove a Rolls-Royce. On the long-running TV show "Jim'll Fix It" he made children's wishes come true. Off-screen, he ran marathons for charity and frequently visited schools and hospitals.

What now seems clear ? what so many missed ? is that both roles brought him into contact with potential victims: star-struck teenagers, vulnerable patients, inmates of a secure psychiatric hospital.

Cary Cooper, a professor of psychology at England's Lancaster University, said that probably nobody will ever know whether Savile used his charity work deliberately to meet victims, or simply to burnish his saintly image. "Either way," Cooper said, "it protected him more, being seen as a philanthropic individual. It served his purpose."

At the funeral, Hall said Saville's charitable legacy would live on. Last month the trustees of two charities that bear his name announced that they were closing down.

FRIENDS IN HIGH PLACES

When Savile died, Prince Charles' office said the heir to the throne and his wife "were saddened to hear of Jimmy Savile's death."

The late DJ boasted of his ties to powerful people, including Prince Charles, the late Princess Diana and former Prime Minister Margaret Thatcher, whom he visited at her country retreat.

His connections may have helped shield him from criticism. Several young people accused Savile of abuse while he was alive, and he was questioned by police, but no charges were laid ? and no newspaper ever printed the allegations.

Now, police are investigating claims of abuse from some 300 people who have come forward since the scandal exploded when allegations about Savile were broadcast in a TV documentary in early October. And police are facing investigation themselves for their failure to act sooner.

Charles' Clarence House office says the prince's relationship with Savile was solely a result of their shared charity work.

REMORSE AND REGRET

"If there's a heaven, he'll be laughing now if he's got time," fellow DJ Tony Prince said at the funeral. "Because if there is a heaven, he'll be introducing Elvis on the clouds."

Younger DJs mentored by Savile were out in force at the memorial, and remembered the flamboyant star fondly. One, Dave Eager, wore a bright yellow sweat shirt saying "Jimmy's Eager Helper."

"Everyone who knew Jimmy knows it was a life-changing experience," he said.

Last month, Eager told The Sun newspaper that he was "completely and utterly gobsmacked" by the allegations against Savile, and felt guilty about failing to stop the abuse.

"You feel traumatized and sorry for the people abused by Jimmy but equally you think, 'Why the bloody hell didn't we see something?'" he said.

A SHATTERED IMAGE

Savile's carefully crafted myth didn't outlive him by long, and he has not rested in peace. His family has had the star's gravestone destroyed in response to public outrage. This week his nephew backed calls to exhume and cremate Savile's body out of respect to other bereaved families.

Of all the words spoken at the funeral a year ago, one comment now sounds prophetic. "None of us really knew the real Jimmy," fellow DJ Mike Read said. "Maybe he didn't even know himself."

Pa.: One last Romney foray for Obama to defend

Campaign signs for both President Barack Obama, and his challenger, Republican presidential candidate, former Massachusetts Gov. Mitt Romney are seen in yards outside Evans City, Pa., Friday, Nov. 2, 2012. In the final days of the presidential campaign, Romney is making a concerted push into Pennsylvania, aided by outside political groups that are spending millions in last minute ads in the state to help erode Obama?s 2008 support. Polling shows Obama holding on to a 4 or 5 percentage point lead over Romney, but the trend has been in Romney?s favor. (AP Photo/Keith Srakocic)

BRYN MAWR, Pa. (AP) ? Rip Scott regrets his 2008 presidential vote for Barack Obama. The 60-year-old real estate company owner is going home to his Republican Party this year. Here in Philadelphia's suburbs where Pennsylvania political fights can be won or lost, Scott's reversal is the evidence Mitt Romney is looking for to merit his sudden, eleventh-hour sortie into the state.

"I just kind of bought into the whole thing," Scott said remorsefully as he headed for a haircut along Philadelphia's affluent Main Line. He said he feels demonized by Democrats as a successful business owner and wonders why Obama considers him one of the wealthy who needs to contribute more in taxes. "I don't feel wealthy," he said.

In the campaign's final days, Romney is making a concerted push into Pennsylvania, aided by outside political groups spending millions in last-minute ads to help erode Obama's support in 2008, when he won it by more than 10 percentage points. Polling shows Obama holding on to a 4 or 5 percentage point lead over Romney, but Romney has been gaining ground.

The incursion raises the question: Can Pennsylvania help Romney win the election, or is the state once again teasing a Republican presidential candidate only to see him fail??

For Romney, still flush with campaign money, a foray into Pennsylvania is not folly. He has spent massive amounts of time and money in neighboring Ohio only to see Obama maintain a slight and stubborn polling lead. Without Ohio, Romney needs Pennsylvania in his column.

Unlike states with early voting, 95 percent of the Pennsylvania votes are expected to be cast on Election Day, justifying a late attempt to sway the outcome. Romney aides argue that Obama is doing worse in the voter-rich Philadelphia suburbs than he did in 2008 and that Romney is doing better than recent Republicans have, and that he can build on the growing GOP strength in the western part of the state.

What's more, Pennsylvania has not been saturated with political advertising, giving Romney and his supporting groups an opportunity to sway last-minute voters with a barrage of ads. Obama is not ignoring the state, and now is buying commercial time in the state as well. He's also sending his most formidable weapon, former President Bill Clinton, to the state Monday to campaign in Pittsburgh, Scranton and in the Philadelphia area.

"Why not?" says Franklin & Marshall College political scientist Terry Madonna, summing up Romney's reasoning for taking a chance with Pennsylvania.

"When they look across the border and see Pennsylvania, which was a 7-, 8- , 9-point state for Obama before the first debate, is now a 4-, 5-point Obama state," he said. "All things being equal, why not hedge their bets?"

Still, the state has been elusive for the GOP. Registered Democrats outnumber Republicans 4-3 in the state. Despite trying, no Republican presidential candidate has won the state since 1988. The closest was in 2004, when President George W. Bush came up 2.5 percentage points short of John Kerry. For Romney to win, Obama would have to do worse than Kerry and Romney would have to do better than Bush.

"Every four years we go through this with Republicans saying that they're going to play in Pennsylvania," Obama deputy campaign manager Stephanie Cutter said. "It's a sign that he can't quite figure out his path to 270 electoral votes, so he's sending out lifelines."

Romney's entry into Pennsylvania comes in the immediate aftermath of Superstorm Sandy, which devastated neighboring New Jersey. The state's southeast has a special relationship with New Jersey, where many of its residents vacation and where New Jersey Gov. Chris Christie is as well-known as Pennsylvania Gov. Tom Corbett, if not better known.

Obama's tour with Christie to survey the storm's damage this week and Christie's compliments for Obama's response are bound to be noticed in some parts of the state.

"The president performs, he's on the ground, he's getting praise by one of the nation's leading Republicans and early supporters of Gov. Romney," Madonna said. "It's certainly helpful. We don't know how helpful."

Romney political director Rich Beeson said Romney will gain in Republican regions where he will push issues of jobs and energy, particularly gas exploration in the northeastern part of the state and coal in the southwest corner. But much of the attention by the two campaigns is in the ring of counties around Democratic-heavy Philadelphia. Romney will campaign in those suburbs this weekend.

With 1 in 5 of Pennsylvania's registered voters living there, the heavily populated, moderate suburbs of Chester, Delaware, Bucks and Montgomery counties are a reliable predictor of who will win the state. Voters there are highly educated and accustomed to splitting their tickets; they tend to lean liberal on environmental and social issues but conservative on fiscal matters.

"The types of voters in places like Bucks County or any of the suburban counties in Philadelphia are not a bad fit for Mitt Romney, especially the moderate Mitt that he's pitched himself as this fall," said Christopher Borick, a pollster and political scientist at Muhlenberg College in Allentown.

"These aren't individuals who are going to say 'Oh, I can't relate at all to a wealthy businessman,'" Borick said, "because in that part of the state a wealthy businessman is not exotic."

Indeed, Beeson sees inroads in those Philadelphia suburbs where Romney could gain from a primary contest when he was labeled a "Massachusetts moderate" by conservative opponents.

It's no wonder that a Romney radio ad playing in Mrs. Marty's Deli stressed his time as Massachusetts governor, working with a Democratic legislature, and his willingness to work across partisan divides as president.

Perry Gresh, 50, a Republican who owns an oil exploration company, said he voted for Ron Paul in the primary but will support Romney as the party's nominee in hopes of seeing a more stable tax structure.

Jonathan Marsh, a 21-year-old software engineer and registered Democrat, said he would vote for Libertarian Gary Johnson if it were not, in essence, a wasted vote. Instead, he will vote for Obama because he finds Romney to be untrustworthy and unreliable.

About 45 minutes away, in Newtown, Warren May, 67, a registered independent, said he will be voting for Romney after supporting Obama in 2008. May said he doesn't regret voting for Obama and struggled to pinpoint exactly why he's switching.

"I don't know what (Obama's) agenda is," May said as he left a drugstore. "He definitely has the smarts to be a great leader, but he didn't show himself to be a great leader."

The Best Part About Google+ Hangouts Is That The Technology ...

One of the underlying features launched originally with the Google+ project was its video conferencing platform, Hangouts. It?s been a success from the perspective of user adoption and also grabbed a partnership for Google with the NFL. Video is an extremely tough space to tackle, just ask companies like Skype, Airtime and countless others. Nailing an intimate experience that supports two or more people in a video conference is no small feat, but Google knocked it out of the park with Hangouts.

Today, the team announced some new features, nothing ?major,? but some really nice things that make the Hangout experience even more enjoyable and easier to use. When you?re in a Hangout, you can now display or hide a new sidebar, which shows you who?s in the room. It also sports a fit-and-finished notification system, which alerts showing in red, actions in blue and announcements in grey. Hangout apps have also been surfaced, illustrating the great work that developers have done using its API.

Yesterday, I had the pleasure of speaking with Product Manager on Google+ Hangouts, Kate Cushing, about what makes Hangouts so special and how the team tackles hard problems like scaling such a service for the masses.

A Hangout About Hangouts

Long story short, I injured myself yesterday, so I couldn?t visit the Googlplex to talk to Cushing. No problem. We jumped in a Google+ Hangout and chatted for a while. Her insightful knowledge of the project is extremely evident, but the nuances that I?ve surfaced in the past only became clearer as we chatted.

Cushing is a recent graduate who was a part of the famed Google APM program, and has been working on Hangouts before it was launched to the public last year. Previously, she worked on Google Analytics, but there was something about Hangouts that caught her attention:

Hangouts is where I wanted to be, it?s an exciting place to be at Google and on the net right now. Real-time communication is the next frontier. When I went away to college it was SMS and voice and for my dad it was letters and phone calls. Now it?s video chatting.

The No. 1 use case for Google+ Hangouts is for hanging out with friends, but companies are adopting it for internal meetings with teams that are spread out all over the world. For example, Cushing works with some of the engineers who aren?t in Mountain View, using Hangouts to get a more ?natural? feel that beats emails, texts and phone calls. Cushing explained this phenomenon quite eloquently:

I think one of the most exciting pieces around what we?re doing with Hangouts is mirroring the real-life interactions you have?but on the web. Tiny details like how we switch video when we?re talking. Switching focus is what you see on a TV show and the kind of focus when you have during a normal group conversation in real life.

I can interrupt you, make a joke, fire out punchlines. The standard parts of conversations that are fun are here in Hangouts, and I can recreate the dinners that I would have with my family.

It?s that real-life mirroring that makes the actual technology behind Hangouts, which is actually quite impressive, essentially disappear. To me, the best technology in the world gets out of the way and lets you do your thing. It?s one of the reasons why I really enjoy using Apple products, because even though everything is pretty, the ?tech? hides itself. I honestly have to say that Google?s products are starting to show those same properties.

New Forms Of Communication

I?ve been a digital native for as long as I can remember. My first gig was with a tech company ? the same company that TechCrunch is under. I used to use AOL chatrooms, Instant Messenger, and before that, BBS. Texting, tweeting, instant messaging and video chat have always been the ?same? as talking in person with someone for me, even though I?d prefer the real thing. It?s not a replacement, but it?s an enhancement when people you care about don?t live nearby.

It?s more than just one-on-one chat though, which is why Hangouts are so magical. Cushing described her own personal experiences with the product to me as we hung out:

I work with a bunch of engineers in a different office and we talk about their kids and I see their Halloween photos like we?re sitting in an office. That isn?t possible without video. The same thing with my family. Last Christmas, since we?re all over the place, my grandparents couldn?t see everyone at Christmas and have never had all of their grandchildren together at once. We gave her a tablet and all of these people showed up after it dings.

She got to meet her first great-grandchild over Hangouts and a tablet.

The Hangout product continues to evolve under the leadership of some visionary folks at Google, but mostly thanks to the feedback from its users and ?ambassadors,? which the Hangouts team works very closely with to learn about how they use the product.

I asked Cushing what her favorite piece of Hangouts was for her personally to work on. Her answer surprised me, but made absolute sense:

I actually did the Hangouts piece for Gmail. That was really cool because we brought free calling to every Gmail caller and the nuances for what that meant was pretty cool. It was fun for me because I have friends who are on Gchat/Gmail all day. It was one of those times when you see people transition from asynchronous ?chats? to easily having a ?conversation.?

The Future Of The Future

There are more places where Hangouts makes sense, like within education. I can totally see classrooms using the product to conduct classes or as a place where students can help one another study for a test. Sure, they could do this on something like Skype, but the Hangouts experience is built for a use case like this.

I mean, during the NBA dunk contest, a player held a Hangout and performed dunks that were requested by the audience. That?s the next level of interactivity on multiple levels. I?d like to see television perform in this way sometime in the future. It could happen.

As I mentioned, the underlying technology behind Hangouts is a massive undertaking. I asked Cushing to talk about the major hurdles of keeping up with the community requests, as well as the wants and needs that the team has for the product:

One of the biggest challenges that we face is balancing the directed communication you want to have with people and at the same time supporting these broader conversations, along with the context and the conversation. We really care about both of those. One is innovating, and one is making it easier to let you instantly connect with someone.

Figuring out how to balance the two uses of the project and deliver on both of them well. That?s kind of the challenge we face.

How do you innovate and keep it simple at the same time? That?s what the team is working on. Along with that, there are things that we don?t ?see,? like incremental improvements to audio and video quality, messaging on its pages and placement of buttons to keep things usable for everyone, not just tech nerds.

There?s a lot going on with Hangouts, but once you start using them, you completely forget that you?re on your computer using a sophisticated technology project. It?s like you?re having dinner with your parents.

Volcanic Eruptions on Jupiter's 'Pizza Moon' Io Spotted from Earth

A team of SETI astronomers have proved it's possible to see volcanic eruptions on Io ? a moon of Jupiter ? from our perch on Earth hundreds of millions of miles away.

Based on 44 nights of telescope observations, the group from the SETI Institute's Carl Sagan Center showed it is possible to see fiery volcanoes spewing on Io (which is also known as Jupiter's "Pizza Moon" for that reason). They can see features as small as 62 miles (100 kilometers) across using a particular telescope technique.

This means we don't necessarily need a spacecraft to watch over Io's volcanoes. That's an important finding considering there won't be another long-term mission at Jupiter until the 2030s, said SETI's Franck Marchis, who led the team.

"We are not going to have a (Jupiter) space mission for several years," said Marchis, the senior planetary astronomer of the Carl Sagan Center. [Amazing Photos: Jupiter's Volcanic Moon Io]

"If we want to continue to invest time in observing volcanic activity, we need to focus on ground-based telescopes. It's not a community that has been used to it ... our goal is really to motivate them to think about it."

?

Bending Io's light

Marchis and his team used a technique called adaptive optics. It's a technology that helps smooth out blurs that conventional telescopes see when trying to take pictures through the turbulent atmosphere of Earth.

A telescope, fitted with a distortable mirror, is hooked up to the adaptive optics system. As the light bends in the atmosphere, a sensor measures the distortions with the assistance of a computer, which makes calculations.

The best systems today can make 1,000 calculations per second, Marchis said, and that figure is improving all the time.

As the number of calculations increase, so does the accuracy. It makes the image look sharper. In Marchis' case, it allowed his team to track the Tvashtar volcano's eruption in 2006-7 at the same time as the New Horizons spacecraft saw it. (New Horizons is en route to Plutoand will arrive in 2015.)

Io isn't the only astronomical target that benefits from adaptive optics. The system has also been used to find planets around distant stars, to image cracks on Europa, and to give a more precise look at Jupiter's atmosphere.

As the resolution improves, Marchis said we'll one day be able to peer at the moons of exoplanets in search of volcano flares and other large phenomena.

"The thermal eruption of these moons may be so strong that we may be able to see them directly with instruments," he said.

An explosive mystery

Io's volcanic processes are poorly understood because we don't have long-term continual observations of the moon, Marchis said. Even when the Galileo spacecraftorbited Jupiter and its moons between 1995 and 2003, it only had brief spells at Io due to the intense, electronics-baking radiation surrounding the moon.

A long-term observation program of Io could solve a mystery that has been puzzling Marchis' team. Io has been unusually quiet in the past two years, and astronomers aren't sure why.

In 13 nights of observation since June 2010, Marchis' team has observed none of the outburst eruptions that characterized the moon in incidents in 2001 and 2007.

Marchis speculated Io might have a long-term cycle of intense volcanic explosions over several years, but more observations are needed, he said.

He speculated Io's volcanoes may need time to refill their chambers in between large outbursts, but he added there is no known process that scientists can correlate with Io's volcanic activity.

Giant telescopes will improve resolution

Marchis' team used three large telescopes (8 to 10 meters in diameter) to watch over Io during the past eight years: W.M. Keck II and Gemini North at Mauna Kea, Hawaii, and Chile's Very Large Telescope No. 4 (also known as Yepun).

He estimates there are about seven telescopes in the world that can do the same kind of searches today, but there are more telescopes under construction that will make the technology even better.

The main telescope Marchis awaits is the planned $1.3 billion Thirty Meter Telescope. When the giant telescope is ready in 2021, the images it will produce will be just 22 miles (35 kilometers) in resolution ? the same resolution as Galileo, Marchis said.

"The point is to mobilize the Io community, because we have been kind of dormant due to the fact there has been no space mission."

NJ to use military trucks as polling places

MOONACHIE, N.J. (AP) ? New Jersey will deploy military trucks to serve as polling places on Election Day in storm-battered communities, the state secretary of the state announced Thursday during a visit to this flood-ravaged town. The state is also extending the deadline on mail-in ballots.

Department of Defense trucks will be parked at regular polling places that have lost power, as long as the sites are still accessible. Paper ballots will be used.

Republican Secretary of State and Lt. Gov. Kim Guadagno said voters will find "a DOD truck with a well-situated National Guardsman and a big sign saying, "Vote Here."

Guadagno said it was still unclear how many of the state's 3,000 polling places are without power, but she would know by Friday. Alternate sites are to be identified in cases where polling places are gone, she said.

More than 1.6 million electric customers in New Jersey remained without power Thursday night.

The state also extended the deadline for when county clerks may accept mail-in ballot applications to the close of business Friday. Election officials said they could be handed in as late as Election Day, by the close of the polls.

The secretary of state urged as many people as possible in storm-damaged areas to vote by mail-in ballot because, she said, "obviously in places like Seaside Heights and Sea Bright, there is no polling place, it's gone."

"There's no reason not to vote, there's no reason not to vote today, there's certainly no reason not to vote on Tuesday, five days from today," Guadagno said.

Gov. Chris Christie said that in areas without electricity, voting would again be "old school."

"You walk up, get a paper ballot, fill it out and hand it back in," he said.

With paper ballots to be counted, the governor said some races might be more suspenseful.

Social factors trump genetic forces in forging friendships, study finds

ScienceDaily (Oct. 31, 2012) ? "Nature teaches beasts to know their friends," wrote Shakespeare. In humans, nature may be less than half of the story, a team led by University of Colorado Boulder researchers has found.

In the first study of its kind, the team found that genetic similarities may help to explain why human birds of a feather flock together, but the full story of why people become friends "is contingent upon the social environment in which individuals interact with one another," the researchers write.

People are more likely to befriend genetically similar people when their environment is stratified, when disparate groups are discouraged from interacting, the study found. When environments were more egalitarian, friends were less likely to share certain genes.

Scientists debate the extent to which genetics or environmental factors -- "nature" or "nurture" -- predict certain behaviors, said Jason Boardman, associate professor of sociology and faculty research associate with the Population Program in CU-Boulder's Institute of Behavioral Science. "For all the social demographic outcomes we care about, whether it's fertility, marriage, migration, health, it's never nature or nurture.

"It's always nature and nurture," he said. "And most of the time it has a lot more to do with nurture."

Boardman's team included Benjamin Domingue, research associate in the Population Program at IBS; and Jason Fletcher, associate professor of health policy at the Yale School of Public Health. Their research was recently published in the Proceedings of the National Academy of Sciences.

Early last year, PNAS published a study reporting evidence that certain shared genes might determine peoples' choice of friends. Time magazine dubbed this "friends with (genetic) benefits."

Boardman is a sociologist who spent five years studying genetics at CU-Boulder's Institute for Behavioral Genetics to bring insights of the social sciences to the natural sciences. He observed: "You can't understand the spread of health behaviors -- why people smoke, why they drink, why they may or may not be obese -- unless you understand their genetic liability and also place them in the right social context."

The research team used data from the National Longitudinal Study of Adolescent Health. Boardman's team focused on 1,503 pairs of friends in seventh through 12th grade in 41 schools. As with the earlier study, Boardman's group found that some pairs of friends shared certain genetic characteristics.

The team tested the evidence, arguing that if genes were the driving friendship factor, genetically based friendship should emerge most often and easily in schools with the least amount of social friction. "But we found the exact opposite," he said.

In the most socially equal environments, genetic homophily (or love of the same) was "pretty weak," meaning that friends were less likely to share genetic traits. He added, "It was in the most unequal social environments that we saw the highest level of genetic homophily."

In a socially stratified school, "Students from different populations within the school may be effectively 'off limits' for friendships," the team wrote.

While applauding the revolutionary advances in genetics in recent years, Boardman said "we have to have social scientists at the table, because we're the ones with the data, methods and theories to characterize the multidimensional and multilevel nature of the social environment."

Scientists cannot fully understand heritable changes in gene expression unless they understand "what kind of schools people go to, what neighborhoods they live in" and other social factors, Boardman said.

"To me, to say whether genes predict friendships without understanding the context within which these friendships may or may not occur just doesn't tell the whole story."
