Divorce early in childhood affects parental relationships in adulthood

June 29, 2013 ? Divorce has a bigger impact on child-parent relationships if it occurs in the first few years of the child's life, according to new research. Those who experience parental divorce early in their childhood tend to have more insecure relationships with their parents as adults than those who experience divorce later, researchers say.

"By studying variation in parental divorce, we are hoping to learn more about how early experiences predict the quality of people's close relationships later in life," says R. Chris Fraley of the University of Illinois at Urbana-Champaign. Psychologists are especially interested in childhood experiences, as their impact can extend into adulthood, but studying such early experiences is challenging, as people's memories of particular events vary widely. Parental divorce is a good event to study, he says, as people can accurately report if and when their parents divorced, even if they do not have perfect recollection of the details.

In two studies published today in Personality and Social Psychology Bulletin, Fraley and graduate student Marie Heffernan examined the timing and effects of divorce on both parental and romantic relationships, as well as differences in how divorce affects relationships with mothers versus fathers. In the first study, they analyzed data from 7,735 people who participated in a survey about personality and close relationships through yourpersonality.net. More than one-third of the survey participants' parents divorced and the average age of divorce was about 9 years old.

The researchers found that individuals from divorced families were less likely to view their current relationships with their parents as secure. And people who experienced parental divorce between birth and 3 to 5 years of age were more insecure in their current relationships with their parents compared to those whose parents divorced later in childhood.

"A person who has a secure relationship with a parent is more likely than someone who is insecure to feel that they can trust the parent," Fraley says. "Such a person is more comfortable depending on the parent and is confident that the parent will be psychologically available when needed."

Although there was a tendency for people to experience more anxiety about romantic relationships if they were from divorced families, the link between parental divorce and insecurity in romantic relationships was relatively weak. This finding was important, the researchers say, as it shows that divorce does not have a blanket effect on all close relationships in adulthood but rather is selective -- affecting some relationships more than others. They also found that parental divorce tends to predict greater insecurity in people's relationships with their fathers than with their mothers.

To help explain why divorce influences maternal relationships more than paternal ones, and to replicate the first study's findings, Fraley and Heffernan repeated their analysis with a new set of 7,500 survey participants. Unlike in the first study, however, they asked the participants to indicate which of their parents had been awarded primary custody following their divorce. The researchers speculated that paternal relationships were more insecure following divorce because mothers are more likely than fathers to be awarded custody.

The majority of participants -- 74 percent -- indicated that they had lived with their mothers following divorce or separation, while 11 percent indicated living with their fathers; the remainder lived with grandparents or other caretakers. The researchers found that people were more likely to have an insecure relationship with their father if they lived with their mother and, conversely, were less likely to have an insecure relationship with their father if they lived with him. The results were similar with respect to mothers.

While it is premature to speculate on the implications of this work for decision-making regarding child custody, the work is valuable as it suggests that "something as basic as the amount of time that one spends with a parent or one's living arrangements" can shape the quality of child-parent relationships, write Fraley and Heffernan.

"People's relationships with their parents and romantic partners play important roles in their lives," Fraley says. "This research brings us one step closer to understanding why it is that some people have relatively secure relationships with close others whereas others have more difficulty opening up to and depending on important people in their lives."

VP Biden: Virginia GOP Slate Extreme Captives of Tea Party Ideology

Vice President Joe Biden continued a busy political pace Saturday, appearing with Virginia's Democratic gubernatorial candidate at the swing state's premier party fundraiser and ridiculing this fall's conservative Republican statewide ticket as extreme captives of tea party ideology.

Biden brought about 1,000 Democrats to their feet repeatedly at the Jefferson-Jackson Dinner barely four months ahead of the nation's only competitive governor's race. His appearances at state fundraisers haved evoked speculation that he is laying his footing for a 2016 presidential bid.

"Ladies and gentlemen, we stand for equal rights and women's rights," Biden said. "With virtually zero support from the Republicans, the president and I have moved the country from the worst recession since the Great Depression to 38 months of private-sector growth."

With Democratic gubernatorial nominee Terry McAuliffe at his side, Biden took aim at McAuliffe's opponent, state Attorney General Ken Cuccinelli, who won the GOP nomination with strong tea party support and his socially conservative ticket mates.

"There is so much they stand for that is so at odds with the value set of Virginians," Biden said.

The vice president warned that a GOP victory in Virginia would only galvanize the tea party's grip on the GOP in Congress, where he said even longtime moderate Republicans are fearful of a primary challenge if they don't do the tea party's bidding.

"They are so afraid of a challenge by the tea party that they vote against what is the right vote. Imagine what they will do to Barack and me if Terry McAuliffe loses," he said.

A McAuliffe victory, he said, would "send a strong signal to Republicans across America that there's no reason to be afraid of these extreme guys."

Before speaking to activists who paid $175 or more per ticket, Biden joined McAuliffe, a longtime confidante of Bill and Hillary Clinton, in surprising patrons at a Richmond restaurant, shaking hands before wolfing down two plates of fried whiting.

Among other campaign events this season, Biden aided Democratic Rep. Ed Markey in a Massachusetts special election ? Markey won, thus keeping Secretary of State John Kerry's old seat in Democratic hands ? and held a series of closed-door "donor-maintenance" events in Washington.

Sen. Tim Kaine, elected on the same Virginia ballot as President Barack Obama last fall, said it's too early for Democrats to take sides in a potential nomination contest between Biden and Hillary Clinton, but he counseled both to try pragmatism over progressive partisanship.

"I think the Virginia Democratic success model is, we'll let the other guys be the ideology people and we will be the work-together, compromise, make-things-happen party. That's been the model that has allowed Dems to win," said Kaine, like McAuliffe, a former Democratic National Committee chairman.

In speeches warming up the crowd, Kaine and Sen. Mark Warner congratulated gay-rights activists for the ruling that cleared the way for same-sex marriages in 13 states but not in Virginia, where a 7-year-old amendment to the state Constitution prohibits it. And both hailed the immigration reform bill that they supported ? it now faces an uncertain future in a conservative Republican-led House.

The Cuccinelli campaign joined the Virginia GOP in using Biden's visit as an occasion to attack the ticket for Obama's clean-energy initiative, warning that it will devastate Virginia's struggling coal industry and drive up utility bills.

"With no economic plan or message to tout, Vice President Biden and Terry McAuliffe doubled down on an empty strategy of division and false attacks tonight," the campaign said in a statement that referred to the "Obama/Biden/McAuliffe War On Coal" and government-run healthcare as "harmful to job growth and economic opportunity in Virginia."

State GOP Chairman Pat Mullins called it "the most anti-coal slate of candidates ever fielded in the history of Virginia," a distinction intended to lock up the rural, rugged but independent southwestern tip of the state for the GOP in a neck-and-neck governor's race.

Republicans weren't alone in protesting Biden's trip. About three dozen environmental activists opposed to construction of the proposed Keystone XL pipeline stood on a street corner as Biden's motorcade passed, waving placards that read "Say No to Big Oil" and chanting "Hey, Joe, you ought to know, Keystone pipeline's got to go."

Danica Patrick fires back at Kyle Petty comments

SPARTA, Ky. (AP) ? Danica Patrick doesn't care that Kyle Petty thinks she's better at getting attention than driving because she's heard it all before.

But if Petty's going to attack her, the NASCAR Sprint Cup rookie believes he should at least get his facts straight.

On Friday, Patrick responded to Petty's comments a night earlier on Speed's "Race Hub" program, in which the former Sprint Cup driver called her a "marketing machine" rather than a race car driver. Petty also doubted that Patrick would become a driver and insisted that she doesn't race as well as she qualifies.

Patrick's statistics suggest otherwise. On average she's finishing almost six spots higher (25.8) than she starts (32nd), which she noted by saying, "those who watch know I can't qualify for crap. The race goes much better."

That likely won't stop Petty, the 53-year-old son of seven-time Cup champion Richard Petty and an eight-time race winner on NASCAR's premier circuit, from criticizing Patrick.

Now an analyst for TNT and Fox/Speed, Petty has periodically taken jabs at Patrick, a former IndyCar Series driver who now drives the No. 10 Chevy for Stewart-Haas Racing. The 31-year-old Patrick is 27th in points in her first full Cup season, which follows an open wheel career highlighted by a fuel-mileage victory in 2008 in Motegi, Japan.

On Thursday night, Petty seemed to elaborate on his views during the show. While he understands the mass appeal of Patrick, who has been featured in racy TV ads for sponsor Go Daddy and was IndyCar's most popular driver for several years, her driving skills don't justify the hype in his opinion.

"That's where I have a problem, where fans have bought into the hype of the marketing, to think she's a race car driver," he said. "She can go fast, and I've seen her go fast. She drives the wheels off it when she goes fast."

Asked if she has learned to race, Petty continued, "She's not a race car driver. There's a difference. The King always had that stupid saying, but it's true, 'Lots of drivers can drive fast, but very few drivers can race.' Danica has been the perfect example of somebody who can qualify better than what she runs. She can go fast, but she can't race."

Patrick won the pole and finished eighth in the season-opening Daytona 500 but has admittedly struggled this season. She said she's working toward that point where things level out but isn't there yet.

The main thing is keeping her team, sponsor and fans happy ? not giving a second thought to Petty's comments.

"I really don't care," she said during a news conference at Kentucky Speedway. "It's true that there are plenty of people who say bad things about me. I read them. People want me to die. At the end of the day, you get over that stuff and trust you are doing a good job."

Asked what it will take to quiet her critics, Patrick's response brought some laughs.

"Do you think I will silence my naysayers?" she asked. "You don't. I'm sure everybody has them. You know who believes in you. That's what matters."

Former boss Dale Earnhardt Jr. has shown his faith in Patrick, giving her a chance to transition to stock cars over three years in the Nationwide Series at JR Motorsports. Earnhardt defended Patrick and called her a tough competitor who works hard and said she wouldn't have a ride if she couldn't stay with the pack or finished last every week.

"I have to disagree with Kyle," Earnhardt said. "She has run some really good races. On every occasion she is outrunning several guys out on the circuit. If she was not able to compete, I think you might be able to say Kyle has an argument.

"But she's out there running competitively and running strong on several accounts. I think that she has got a good opportunity and a rightful position in the sport to keep competing and she just might surprise even Kyle Petty."

As in 1983, Morocco's under 20 team wins gold medal against Turkey

By Mouhcine Abdechafi

Morocco World News

Tinghir, Morocco, June 28, 2013

The Moroccan football team participated successfully in the seventeenth edition of the Mediterranean Games, taking place in Missrin in Turkey. The Moroccan team managed to?secure the gold medal on Thursday, after it won the match against the host country?s national team via penalties. The match ended in a tie of 2-2 and the winner was then decided by penalty kicks.

The Moroccan national team, made up of players under 20, attained the same medal in Casablanca in 1983 when it won the match against the same team, Turkey, 3-0. This new achievement was due to the hard work and determination of the local coach Hassan Benaabicha, along with a group of players from the local league.

Moroccan player Hicham Kheloua, who plyas in Spain, scored in the first minute. Soon after in the thirteenth minute, the Turkish team managed to equalize. In the twenty-sixth minute, the Turkish team scored again and was close to winning the match before Adam Nefani, who plays in France, managed to tie the score. With the score 2-2, the two teams resorted to penalties, which turned in favor of Morocco.

Large-scale quantum chip validated: Prototype quantum optimization chip operates as hoped

June 28, 2013 ? A team of scientists at USC has verified that quantum effects are indeed at play in the first commercial quantum optimization processor.

The team demonstrated that the D-Wave processor housed at the USC-Lockheed Martin Quantum Computing Center behaves in a manner that indicates that quantum mechanics plays a functional role in the way it works. The demonstration involved a small subset of the chip's 128 qubits.

This means that the device appears to be operating as a quantum processor -- something that scientists had hoped for but have needed extensive testing to verify.

The quantum processor was purchased from Canadian manufacturer D-Wave nearly two years ago by Lockheed Martin and housed at the USC Viterbi Information Sciences Institute (ISI). As the first of its kind, the task for scientists putting it through its paces was to determine whether the quantum computer was operating as hoped.

"Using a specific test problem involving eight qubits we have verified that the D-Wave processor performs optimization calculations (that is, finds lowest energy solutions) using a procedure that is consistent with quantum annealing and is inconsistent with the predictions of classical annealing," said Daniel Lidar, scientific director of the Quantum Computing Center and one of the researchers on the team, who holds joint appointments with the USC Viterbi School of Engineering and the USC Dornsife College of Letters, Arts and Sciences.

Quantum annealing is a method of solving optimization problems using quantum mechanics -- at a large enough scale, potentially much faster than a traditional processor can.

Research institutions throughout the world build and use quantum processors, but most only have a few quantum bits, or "qubits."

Qubits have the capability of encoding the two digits of one and zero at the same time -- as opposed to traditional bits, which can encode distinctly either a one or a zero. This property, called "superposition," along with the ability of quantum states to "tunnel" through energy barriers, are hoped to play a role in helping future generations of the D-Wave processor to ultimately perform optimization calculations much faster than traditional processors.

With 108 functional qubits, the D-Wave processor at USC inspired hopes for a significant advance in the field of quantum computing when it was installed in October 2011 -- provided it worked as a quantum information processor. Quantum processors can fall victim to a phenomenon called "decoherence," which stifles their ability to behave in a quantum fashion.

The USC team's research shows that the chip, in fact, performed largely as hoped, demonstrating the potential for quantum optimization on a larger-than-ever scale.

"Our work seems to show that, from a purely physical point of view, quantum effects play a functional role in information processing in the D-Wave processor," said Sergio Boixo, first author of the research paper, who conducted the research while he was a computer scientist at ISI and research assistant professor at the USC Viterbi School of Engineering.

Boixo and Lidar collaborated with Tameem Albash, postdoctoral research associate in physics at USC Dornsife; Federico M. Spedalieri, computer scientist at ISI; and Nicholas Chancellor, a recent physics graduate at USC Dornsife. Their findings will be published in Nature Communications on June 28.

The news comes just two months after the Quantum Computing Center's original D-Wave processor -- known commercially as the "Rainier" chip -- was upgraded to a new 512-qubit "Vesuvius" chip. The Quantum Computing Center, which includes a magnetically shielded box that is kept frigid (near absolute zero) to protect the computer against decoherence, was designed to be upgradable to keep up with the latest developments in the field.

The new Vesuvius chip at USC is currently the only one in operation outside of D-Wave. A second such chip, owned by Google and housed at NASA's Ames Research Center in Moffett Field, California, is expected to become operational later this year.

Next, the USC team will take the Vesuvius chip for a test drive, putting it through the same paces as the Rainier chip.

This research was supported by the Lockheed Martin Corporation; U.S. Army Research Office grant number W911NF-12-1-0523; National Science Foundation grant number CHM-1037992, ARO Multidisciplinary University Research Initiative grant W911NF-11-1-026.

Math targets cities' essence

New formula relates city size to infrastructure, productivity

By Rachel Ehrenberg

Print edition: July 13, 2013; Vol.184 #1 (p. 5)

Though strikingly different in culture and layout, cities like London and Beijing share many properties with regard to infrastructure, social interactions and productivity.

The notion that cities are all alike borders on blasphemy. Residents of the world?s great metropolises, from New York to London to Tokyo, speak of their homes as of a first love or old friend. But decades of analyses hint that cities, mathematically speaking, might actually all be the same. Now for the first time, those observations have been tidily and elegantly drawn together into a formula that describes what a city is.

That new work is part of a growing field dedicated to the science of cities. The effort is a timely one: Roughly 75 percent of people in the developed world now live in urban environments. While much of the research is in its early days, eventually it may serve as a powerful, widely used tool for urban planners and policymakers.

The mathematical work is rooted in and reinforces the view ?that cities grow from the bottom up,? says Michael Batty, who trained as an architect, planner and geographer and went on to found the Centre for Advanced Spatial Analysis at University College London. ?The diversity of life [in cities] offers greater opportunities for mixing ideas.?

That diversity, which includes dismal poverty, squalid slums and crime juxtaposed with prosperous businesses, majestic parks and great art institutions, was much decried in the 19th century. In 1883, for example, textile designer and artist William Morris lamented England?s cities as ?mere masses of sordidness, filth, and squalor, embroidered with patches of pompous and vulgar hideousness, no less revolting to the eye and the mind?.?

Discomfort with the notion that cities grew from the bottom up went along with disdain for disorder and chaos, framing cities as a problem to be solved. This view prevailed into the 20th century and influenced postwar urban renewal projects across the United States. The resulting redevelopment forever changed parts of cities such as Pittsburgh and Boston, with mixed results.

In the last several decades, however, the view of cities as disordered systems has begun to change, Batty says. Patterns have emerged within the chaos. Researchers in economics, physics, complexity theory and statistical mechanics have observed that certain features of cities consistently vary with population size.

But the relationships aren?t direct and linear. As a city grows, some features, such as land area, grow more slowly with respect to population. This ?sublinear? relationship also holds for some aspects of physical infrastructure, such as the length of pipes and roads: As population grows, proportionately less infra?structure is required to support each additional person.

For other characteristics, the reverse is true: Some measures grow faster with respect to the population. This ?superlinear? scaling has been observed for a number of socioeconomic factors in cities around the world. Produced wealth, whether measured as income, wages or gross domestic product, increases at a rate greater than the population. So does crime. Markers of innovation, including the number of patents produced and number of jobs in creative fields like the arts and sciences, also increase superlinearly.

While there?s some quibbling about the exact mathematical values, the relationships among city characteristics generally hold, says physicist and complex systems scientist Lu?s Bettencourt of the Santa Fe Institute in New Mexico.

Bettencourt, with other researchers at the Santa Fe Institute and colleagues elsewhere, has been examining these relationships for more than a decade. Now Bettencourt has created a series of equations, published in the June 21 Science, that pull the relationships together into a mathematical theory of cities.

Bettencourt?s math stands on four basic assumptions: First, cities mix varied people together, allowing them to reach each other. Next, cities are networks that grow gradually and incrementally, connecting people. Third, human effort isn?t limitless and stays the same regardless of urban size. And finally, measures of the socioeconomic output of a city ? things like the number of patents awarded or crime rate ? are proportional to the number of social interactions.

Bettencourt?s theory captures the interplay between a city?s population, its area, the properties of its infrastructure and its social connectivity. By mathematically describing the tension between a city?s number of social interactions, their outcome (innovation, for example, or crime), and the transportation and energy costs of enabling those interactions, Bettencourt arrives at a parameter that he calls G*. The closer a city?s value is to G* the more effective it is at producing positive interactions and all the benefits that flow from them.

?In a nutshell, the city is the best way of creating a vast, open-ended social network that minimizes the cost of moving things in and around an environment,? Bettencourt says. ?When people brush up against each other, that?s when the magic of the city happens ? the social reactor begins to work.?

That conclusion isn?t so surprising, Batty says. Consider how a concentration of creative genius and technological know-how has made Silicon Valley into one of the world?s foremost engines of wealth. Bettencourt?s theory ?basically unpacks the equations and then puts it all together and leads us to what we observe in a clean and elegant way,? Batty says.

In many respects, the theory formalizes what writer and activist Jane Jacobs articulated in her 1961 book, The Death and Life of Great American Cities. Earlier scholars? emphasis on aesthetics and form missed what makes cities so great, she argued. Cities are a way of sustaining an enormous number of social interactions through time, she wrote, ?a most intricate and close-grained diversity of uses that give each other constant mutual support, both economically and socially.?

What urban planners and policymakers will take from Bettencourt?s new theory remains to be seen. The research suggests that enabling mixing of people and fostering the creation and spread of ideas is never a bad idea. It also suggests that city planning should not involve grand, top-down projects, but perhaps well-considered smaller ones.

?We need to identify the minimal interventions that can lead to the greatest gains,? Batty says. ?Complexity theory teaches us that things are a good deal more complex than we think, and when we interfere, it can be at our peril.?



Back Story | Ahead of her time

Writer and activist Jane Jacobs did not pull punches. ?This book is an attack on current city planning and rebuilding,? begins the introduction to her 1961 book The Death and Life of Great American Cities. The book was a reaction to the postwar urban renewal projects of her time. But it was also prescient, foreshadowing a view of cities as complex systems ? a view that researchers increasingly embrace today. ?The kind of problem which cities pose,? Jacobs wrote, is ?a problem in handling organized complexity.? That perspective is enriched and expanded upon in work by complex systems scientist Lu?s Bettencourt of the Santa Fe Institute. For years, Bettencourt says, discussions of cities have emphasized form over function. Bettencourt?s work, he says, ?is an attempt to shift perspective from what a city looks like to what a city is. Cities are social reactors.?


In addition to her writing, Jane Jacobs, who died in 2006, was known for her protest of the construction of the Lower Manhattan Expressway (map shows proposed development), which would have bisected Soho and nearby neighborhoods.

Appeals board upholds permit for Christo project

DENVER (AP) ? An appeals board is upholding the Bureau of Land Management's decision to grant the artist Christo a permit for his Over the River project, which involves temporarily suspending 5.9 miles worth of silvery fabric panels in sections over 42 miles of the Arkansas River.

The Interior Board of Land Appeals on Friday rejected arguments that the BLM didn't fully consider impacts of Over the River before granting the permit.

Meanwhile, two lawsuits challenging Over the River in state and federal courts are still pending.

"We can now move on from the agency hijinks and into federal court where we can get an unbiased review of this project," said Michael Harris, a lawyer representing the group Rags Over the Arkansas River, which is trying to block Christo's plan. "We fully expect the court to find that the OTR project approval is illegal."

New York-based Christo said in a written statement that he remains confident that state and federal permitting processes were thorough and complete. "This is one of three legal hurdles that needed to be overcome, and I am very happy with this decision," Christo said.

Even if Christo wins in the lawsuits, it would be at least 2016 before the project would be ready for public display.

He and his late wife, Jeanne-Claude, got their first inkling for Over the River in 1992.

Work to set up a system of anchors and cables to suspend the fabric panels over the river would unfold over roughly two years. The project would be displayed for two weeks in the month of August, when the river would be calm enough for rafters to peer up at the fabric as they float underneath and when drivers on U.S. 50 along the river could look down.

Denver-based environmental consultant Rocky Smith, who was among those filing the administrative appeal of the BLM's permitting decision, said he still thinks Over the River is "horribly inappropriate" for the canyon Christo plans to use.

Opponents contend the project threatens bighorn sheep, public safety, traffic on U.S. 50, and businesses that depend on the scenic river to draw anglers, rafters and tourists.

Christo's team has said it plans dozens of measures to mitigate impacts.

'Wi-Vi' is based on a concept similar to radar and sonar imaging

CAMBRIDGE, MA -- The comic-book hero Superman uses his X-ray vision to spot bad guys lurking behind walls and other objects. Now we could all have X-ray vision, thanks to researchers at MIT's Computer Science and Artificial Intelligence Laboratory.

Researchers have long attempted to build a device capable of seeing people through walls. However, previous efforts to develop such a system have involved the use of expensive and bulky radar technology that uses a part of the electromagnetic spectrum only available to the military.

Now a system being developed by Dina Katabi, a professor in MIT's Department of Electrical Engineering and Computer Science, and her graduate student Fadel Adib, could give all of us the ability to spot people in different rooms using low-cost Wi-Fi technology. "We wanted to create a device that is low-power, portable and simple enough for anyone to use, to give people the ability to see through walls and closed doors," Katabi says.

The system, called "Wi-Vi," is based on a concept similar to radar and sonar imaging. But in contrast to radar and sonar, it transmits a low-power Wi-Fi signal and uses its reflections to track moving humans. It can do so even if the humans are in closed rooms or hiding behind a wall.

As a Wi-Fi signal is transmitted at a wall, a portion of the signal penetrates through it, reflecting off any humans on the other side. However, only a tiny fraction of the signal makes it through to the other room, with the rest being reflected by the wall, or by other objects. "So we had to come up with a technology that could cancel out all these other reflections, and keep only those from the moving human body," Katabi says.

Motion detector

To do this, the system uses two transmit antennas and a single receiver. The two antennas transmit almost identical signals, except that the signal from the second receiver is the inverse of the first. As a result, the two signals interfere with each other in such a way as to cancel each other out. Since any static objects that the signals hit including the wall create identical reflections, they too are cancelled out by this nulling effect.

In this way, only those reflections that change between the two signals, such as those from a moving object, arrive back at the receiver, Adib says. "So, if the person moves behind the wall, all reflections from static objects are cancelled out, and the only thing registered by the device is the moving human."

Once the system has cancelled out all of the reflections from static objects, it can then concentrate on tracking the person as he or she moves around the room. Most previous attempts to track moving targets through walls have done so using an array of spaced antennas, which each capture the signal reflected off a person moving through the environment. But this would be too expensive and bulky for use in a handheld device.

So instead Wi-Vi uses just one receiver. As the person moves through the room, his or her distance from the receiver changes, meaning the time it takes for the reflected signal to make its way back to the receiver changes too. The system then uses this information to calculate where the person is at any one time.

Possible uses in disaster recovery, personal safety, gaming

Wi-Vi, being presented at the Sigcomm conference in Hong Kong in August, could be used to help search-and-rescue teams to find survivors trapped in rubble after an earthquake, say, or to allow police officers to identify the number and movement of criminals within a building to avoid walking into an ambush.

It could also be used as a personal safety device, Katabi says: "If you are walking at night and you have the feeling that someone is following you, then you could use it to check if there is someone behind the fence or behind a corner."

The device can also detect gestures or movements by a person standing behind a wall, such as a wave of the arm, Katabi says. This would allow it to be used as a gesture-based interface for controlling lighting or appliances within the home, such as turning off the lights in another room with a wave of the arm.

Unlike today's interactive gaming devices, where users must stay in front of the console and its camera at all times, users could still interact with the system while in another room, for example. This could open up the possibility of more complex and interesting games, Katabi says.

With multiple missions, US military steps up Africa focus

By Peter Apps, Political Risk Correspondent

WASHINGTON (Reuters) - Striking Islamist militants with drones, supporting African forces in stabilizing Somalia and Mali and deploying dozens of training teams, the U.S. military has returned to Africa.

Its presence remains mostly low key, barely mentioned in the context of President Barack Obama's visit this week to Africa.

Nevertheless, with some 4,000-5,000 personnel on the ground at any given time, the United States now has more troops in Africa than at any point since its Somalia intervention two decades ago. That ended in humiliation and withdrawal after the 1993 "Blackhawk Down" debacle in which 18 U.S. soldiers died.

There are two main reasons behind the build up: to counter al Qaeda and other militant groups, and to win influence in a continent that could become an increasingly important destination for American trade and investment as China's presence grows in Africa.

Obama's eight-day trip is heavily focused not on military issues but on trade and economic development in visits to Senegal, South Africa and Tanzania.

In the Horn of Africa, the vast majority of U.S. forces deployed in Africa are at a major French military base in Djibouti, a tiny country sandwiched between northern Somalia, Ethiopia and Eritrea.

While U.S. officials will not comment in detail on what happens at the base, experts say it has provided a staging post for occasional special forces deployments and drone and air attacks against Islamist militant targets in Somalia.

Dramatic as those actions are, smaller U.S. operations and outreach programs often with only a handful of troops are key to the strategy of winning influence in a continent where China has surpassed the United States as the No.1 trade partner and has huge mining, energy and infrastructure investments.

Such limited missions, U.S. officers say, have gone a long way to reducing initial African skepticism over Germany-based AFRICOM, set up in 2008 to bring all U.S. military activity in Africa under one unified command, rather than dividing responsibility between commanders in Europe, the Middle East and Asia.

"We are focusing on building human capital," says Major General Charles Hooper, head of strategy and plans at AFRICOM. "The smaller missions can be some of the most effective when it comes to gaining trust."

In Angola, Namibia, Democratic Republic of Congo and elsewhere, U.S. engineers have helped train local counterparts in landmine clearance. In southern Africa, military medics have helped local armies tackle HIV infection while in Mauritania, the focus has been on veterinary aid to local ranchers.

U.S. warships combating piracy off both East and West Africa are increasingly frequent visitors to local ports.

One U.S. aim is to convince African militaries their interests are best served by remaining democratically accountable and not interfering in politics.

Some operations, however, have hit just that problem. The hunt in Central African Republic for Ugandan warlord and head of the rebel Lord's Resistance Army Joseph Kony has largely been suspended following a March coup in CAR.

The anti-LRA mission had been the only one in Africa in which combat troops were deployed, involving just over 100 U.S. special forces personnel. U.S. forces continue to train Ugandan and other armies as part of that operation.

KICKED OUT OF MOROCCO, ACTIVE IN SOMALIA

Critics in Africa complain Washington's approach to the continent has become increasingly militarized and focused on counterterrorism. Others worry U.S. military clout may ultimately be used to seize resources.

Administration officials disagree and point to Obama's visit as evidence of U.S. intentions.

"This trip ultimately disproves the notion that we're somehow securitizing the relationship with Africa," Deputy National Security Adviser Ben Rhodes told a conference call last week. "This trip is expressly devoted to trade and investment, democratic institution-building, young people and unleashing economic growth through some of our development priority."

In general, U.S. forces have only been able to operate when African governments - or sometimes France, which maintains a network of bases in former colonies - allow them to.

Permission can be quickly withdrawn for political reasons.

In April, Morocco canceled its annual Exercise African Lion with U.S. forces after a suggestion from Washington that U.N. monitors in the disputed Western Sahara region should extend their mandate to include human rights.

The United States still treads carefully in Somalia, the scene of a serious reverse in 1993 when militia fighters killed 18 Americans on a mission to capture a Somali warlord in support of a U.N. mission.

U.S. officials say there are often one or two U.S. liaison officers deployed inside Somalia helping African Union forces fight Islamist group al Shabaab - which is linked to al Qaeda - on behalf of Somalia's transitional government.

Most of the U.S. support for the African Union mission AMISOM remains outside the country, training forces in Kenya, Uganda and elsewhere.

It is a similar picture on the other side of the continent, where the U.S. military is also acting primarily in support of local nations and France.

The aftermath of the 2011 Libya war has seen a flood of weapons and militants across the Sahel, fueling the rise of al Qaeda in the Islamic Maghreb which briefly captured much of northern Mali before a French offensive there earlier this year.

The U.S. Air Force provided much of the transport for both African and French reinforcements in Mali, while U.S. air tankers from RAF Mildenhall in England have flown long missions over the Sahara refueling French combat jets.

Some 100 U.S. personnel deployed to Niger to set up a drone base. Unlike in East Africa, however, the drones will be unarmed and used only for reconnaissance to track Islamist militants.

U.S. and African officials say Washington has long been reluctant to share its most sophisticated intelligence with African partners, in part over worries it might fall into the wrong hands.

African officers say that if they are to be truly effective at fighting militants in their own countries and as part of broader Mali-type missions, they need to know as much as possible about rebel movements, locations and plans.

"The Americans are our friends - but often they are friends who are not frank," says former Senegalese army chief Mansour Seck, also an ex-ambassador to Washington. "They have a tendency to ask you what you have but will not tell you what they have."

BOSTON (AP) ? What Dzhokhar Tsarnaev needed to learn to make explosives with a pressure cooker was at his fingertips in jihadist files on the Internet, according to a federal indictment accusing him of carrying out the bombings at the Boston Marathon that killed three people and injured dozens more.

Investigators have been trying to determine whether Tsarnaev's older brother, Tamerlan, who was killed while the two were on the run after the bombings, was influenced or trained by Islamic militants during a trip overseas. But the indictment released Thursday against 19-year-old Dzhokhar makes no mention of any overseas influence.

Before the attack, according to the indictment, he downloaded the summer 2010 issue of Inspire, an online English-language magazine published by al-Qaida. The issue detailed how to make bombs from pressure cookers, explosive powder extracted from fireworks and lethal shrapnel.

He also downloaded extremist Muslim literature, including "Defense of the Muslim Lands, the First Obligation After Imam," which advocates "violence designed to terrorize the perceived enemies of Islam," the indictment said. The article was written by the late Abdullah Azzam, whose legacy has inspired terrorist attacks in the Middle East.

Another tract downloaded ? titled "The Slicing Sword, Against the One Who Forms Allegiances With the Disbelievers and Takes Them as Supporters Instead of Allah, His Messenger and the Believers" ? included a foreword by Anwar al-Awlaki, an American propagandist for al-Qaida who was killed in a U.S. drone strike in 2011.

The 30-count indictment provides one of the most detailed public explanations to date of the brothers' alleged motive ? Islamic extremism ? and the role the Internet may have played in influencing them.

"Tamerlan Tsarnaev's justice will be in the next world, but for his brother, accountability will begin right here in the district of Massachusetts," Suffolk District Attorney Daniel Conley, whose jurisdiction includes Boston, said at a news conference with federal prosecutors on Thursday.

The indictment contains the bombing charges, punishable by the death penalty, that were brought in April against Tsarnaev, including use of a weapon of mass destruction to kill. It also contains many new charges covering the slaying of an MIT police officer and the carjacking of a motorist during the getaway attempt that left Tamerlan Tsarnaev dead.

U.S. Attorney Carmen Ortiz of Massachusetts said Attorney General Eric Holder will decide whether to pursue the death penalty against Tsarnaev, who will be arraigned on July 10.

Three people were killed and more than 260 wounded by the two pressure-cooker bombs that went off near the finish line of the marathon on April 15.

Dzhokhar Tsarnaev was captured four days later, hiding in a boat parked in a backyard in Watertown, Mass.

According to the indictment, he scrawled messages on the inside of the vessel that said, among other things, "The U.S. Government is killing our innocent civilians," ''I can't stand to see such evil go unpunished," and "We Muslims are one body, you hurt one you hurt us all."

The Tsarnaev brothers had roots in the turbulent Russian regions of Dagestan and Chechnya, which have become recruiting grounds for Muslim extremists. They had been living in the U.S. about a decade.

There was no mention in the indictment of any larger conspiracy beyond the brothers, and no reference to any direct overseas contacts with extremists. Instead, the indictment suggests the Internet played an important role in the suspects' radicalization.

Tamerlan Tsarnaev spent six months in Dagestan last year, and investigators traveled to the Russian province to talk to the men's parents and try to determine whether he was influenced or trained by local Islamic militants.

Christina DiIorio-Sterling, a spokeswoman for Ortiz, declined to comment on why the indictment did not mention whether authorities believe the elder Tsarnaev received any training during his stay in Russia.

The indictment assembled and confirmed details of the case that have been widely reported over the past two months, and added new pieces of information.

For example, it corroborated reports that Tamerlan Tsarnaev bought 48 mortar shells from a Seabrook, N.H., fireworks store. It also disclosed that he used the Internet to order electronic components that could be used in making bombs.

The papers detail how the brothers then allegedly placed knapsacks containing shrapnel-packed bombs near the finish line of the 26.2-mile race.

The court papers also corroborated reports by authorities that Dzhokhar Tsarnaev contributed to his brother's death by accidentally running him over with a stolen vehicle during a shootout and police chase.

The charges cover the slaying of Massachusetts Institute of Technology police officer Sean Collier, who authorities said was shot in the head at close range in his cruiser by the Tsarnaevs, who tried to take his gun.

In addition, prosecutors said that during the carjacking, the Tsarnaevs forced the motorist to turn over his ATM card and his password, and Dzhokhar withdrew $800 from the man's account.

At the same time the federal indictment was announced, Massachusetts authorities brought a 15-count state indictment against Dzhokhar over the MIT officer's slaying and the police shootout.

Making hydrogenation greener: Using iron as catalyst for widely used chemical process, replacing heavy metals

June 27, 2013 ? Researchers from McGill University, RIKEN (The Institute of Physical and Chemical Research, Wako, Japan) and the Institute for Molecular Science (Okazaki, Japan) have discovered a way to make the widely used chemical process of hydrogenation more environmentally friendly -- and less expensive.

Hydrogenation is a chemical process used in a wide range of industrial applications, from food products, such as margarine, to petrochemicals and pharmaceuticals. The process typically involves the use of heavy metals, such as palladium or platinum, to catalyze the chemical reaction. While these metals are very efficient catalysts, they are also non-renewable, costly, and subject to sharp price fluctuations on international markets.

Because these metals are also toxic, even in small quantities, they also raise environmental and safety concerns. Pharmaceutical companies, for example, must use expensive purification methods to limit residual levels of these elements in pharmaceutical products. Iron, by contrast, is both naturally abundant and far less toxic than heavy metals.

Previous work by other researchers has shown that iron nanoparticles -- tiny pieces of metallic iron -- can be used to activate the hydrogenation reaction. Iron, however, has a well-known drawback: it rusts in the presence of oxygen or water. When rusted, iron nanoparticles stop acting as hydrogenation catalysts. This problem, which occurs with so much as trace quantities of water, has prevented iron nanoparticles from being used in industry.

In research published today in the journal Green Chemistry, scientists from McGill, RIKEN, and the Institute for Molecular Science report that they have found a way to overcome this limitation, making iron an active catalyst in water-ethanol mixtures containing up to 90% water.

The key to this new method is to produce the particles directly inside a polymer matrix, composed of amphiphilic polymers based on polystyrene and polyethylene glycol. The polymer acts as a wrapping film that protects the iron surface from rusting in the presence of water, while allowing the reactants to reach the water and react.

This innovation enabled the researchers to use iron nanoparticles as catalyst in a flow system, raising the possibility that iron could be used to replace platinum-series metals for hydrogenation under industrial conditions.

"Our research is now focused on achieving a better understanding of how the polymers are protecting the surface of the iron from water, while at the same time allowing the iron to interact with the substrate," says Audrey Moores, an assistant professor of chemistry at McGill and co-corresponding author of the paper.

The results stem from an ongoing collaboration between McGill and RIKEN, one of Japan's largest scientific research organizations, in the fields of nanotechnology and green chemistry. Lead author Reuben Hudson, a doctoral student at McGill, worked on the project at the RIKEN Center for Sustainable Resource Science and at the Institute for Molecular Science in Japan. Co-authors of the paper are Prof. Chao-Jun Li of McGill, Dr. Go Hamasaka and Dr. Takao Osako of the Institute for Molecular Science, Dr. Yoichi M.A. Yamada of Riken and Prof. Yasuhiro Uozumi of Riken and the Institute for Molecular Science.

"The approach we have developed through this collaboration could lead to more sustainable industrial processes," says Prof. Uozumi. "This technique provides a system in which the reaction can happen over and over with the same small amount of a catalytic material, and it enables it to take place in almost pure water -- the green solvent par excellence."

Funding for the research was provided by the Natural Sciences and Engineering Research Council of Canada (NSERC), the Canada Foundation for Innovation (CFI), the Canada Research Chairs, the Fonds de recherche du Qu?bec -- Nature et technologies, the Riken-McGill Fund, the Japan Society for the Promotion of Science (JSPS), and the Japan Science and Technology Agency (JST).

Google refreshes Maps and Earth with 800,000 megapixels of new satellite imagery

It's not easy being a satellite; permanent imaging gear becomes outdated mere months after launch, and Mother Nature is constantly caught photobombing close-ups, throwing naughty clouds between a lens and the shot. All that makes for some pretty inconsistent online viewing. Fortunately, Google's stepped in to set things straight, combining the magic of photo stitching with the capture power of a brand-spanking-new Landsat 8. The result is a cloud-free planet, enabling millions of web-equipped "explorers" to realize improved aerial views as seen from 438 miles above sea level. It's pretty spectacular, and it's about friggin' time.
