Curry leads Warriors past Denver 115-101 in Game 4

OAKLAND, Calif. (AP) ? Stephen Curry shook off a sore left ankle to score 22 of his 31 points in the third quarter, leading the Golden State Warriors past the Denver Nuggets 115-101 on Sunday night for a commanding 3-1 series lead.

Curry shot 10 of 16 from the floor and added seven assists in a dominant and dazzling display that rivaled his days in the NCAA tournament for tiny Davidson. His five 3-pointers in the third quarter lifted Golden State to a 20-point lead and its third straight victory in this frenetic and flashy series.

Jarrett Jack added 21 points and nine assists and Andrew Bogut broke out in the first half with 12 points and five rebounds for the sixth-seeded Warriors, who can close out the Nuggets in Game 5 on Tuesday night in Denver.

Ty Lawson scored 26 points and Andre Iguodala had 19 for the third-seeded Nuggets.

The Warriors lost All-Star forward David Lee to a season-ending hip injury in Game 1, and Curry sprained his left ankle late in Game 2. With Curry carrying the load anyway, none of it has seemed to matter.

The quick-shooting point guard hit 5 of 8 from beyond the arc in a spectacular third quarter, when nearly every gold-shirt wearing fan in the sellout crowd of 19,596 stood and cheered. Curry scored all 22 points in the final 6:22 of the quarter, showing the kind of range that helped him make 272 3-pointers in the regular season ? three more than Ray Allen's record set in 2005-06 with Seattle.

Curry capped his remarkable run with two of his most highlight-reel plays.

He stole the ball from Lawson, stopped in heavy traffic and dropped in a 27-footer before sprinting all the way to the bench high-fiving and chest-bumping teammates. Following a timeout, Curry sprung free near Denver's bench for a corner 3 that gave Golden State a 91-72 lead entering the fourth.

Curry's five 3s in the quarter were a Warriors record for a half.

Curry, wearing heavy tape around his nagging ankle, gave fans a scare when Corey Brewer poked Curry in the eye going for a rebound early in the fourth. Curry returned about 4? minutes later, receiving another standing ovation from the home fans.

While Curry scored only seven points in the first half, Bogut broke out in a big way to provide the one-two punch Golden State had long envisioned.

The 7-footer from Australia sliced down a wide open lane off a pick-and-roll with Curry in the first quarter, took one dribble and dunked over JaVale McGee with a thunderous right-handed slam. Bogut, who received a technical foul in Game 3 for daring Denver's big man to punch him on the chin during a face-to-face altercation, stared back at McGee while backpedalling down court.

In the second quarter, Bogut backed down Kosta Koufos before hammering home another dunk. He also soared high for a backdoor alley-oop from Curry to help the Warriors go ahead 45-37, and chants of "Bogut! Bogut!" echoed around the arena while the video board kept replaying his dunks.

Bogut sat out the final 4:37 of the first half with three fouls, and Andre Miller almost single-handily brought Denver back within a point. Then Curry hit his first 3-pointer of the game ? officially a 27-footer that seemed closer to the scorer's table than the arc ? as Golden State scored the last 11 points before the break to go ahead 56-44.

After falling behind by 15 early in the third quarter, the Nuggets started to rally behind their point guard.

Lawson, who scored a career-playoff high 35 points in the Game 3 loss, shook off a slow start to highlight a 14-4 run that sliced Golden State's lead to 62-58 midway through the third quarter. Just when it seemed they might crawl back, Curry countered with a devastating blow to Denver's playoff hopes.

NOTES: For the third straight game, Warriors coach Mark Jackson listed Carl Landry at power forward in his starting lineup submitted before the game, even though Harrison Barnes started at power forward and Landry came off the bench. Jackson said beforehand that he'd do it again because "it worked." Nuggets coach George Karl said it's not what coaches typically do but joked that Jackson is "consistent" and maybe "superstitious." ... Jackson's wife, Desiree Coleman Jackson, sang the national anthem.

Do I Really Need A Gaming Computer? - TechSling Weblog

Playing computer games on a regular computer can be a real pain and can take any enjoyment out of a game. The constant crashing and the slow running game speed is enough to turn any gaming fan away from games completely. ?If you?re an avid gamer still using your regular home desktop PC, it might be time to decide whether you are an avid gamer at all, before asking yourself the question: ?Do I need a gaming computer??

gaming pcs

Gaming computers can offer a far better gaming experience for users than regular PC?s can. However, with this improved gaming experience comes a reduction in regular features.

Below is a list which details the difference between regular computers and gaming computers:

  1. Applications: Generally, computers specifically made for gaming are likely to have a lot less programmes which come as standard on a regular computer. In other words, a gaming computer is far likely to have a Microsoft office package, and instead will have more gaming orientated programmes. The reason for this is that for computers to be able to play games at the optimum level, more space and power is needed specifically for games, not for unrelated programmes.
  2. Components: A gaming computer is likely to have a far better graphics card so as to ensure that a games graphics are as high definition and as realistic as possible, offering the gamer a better experience. It?s also likely that a gaming computer will have more storage and a much faster process than a standard PC. Most companies selling gaming computers and gaming pc?s will offer the opportunity to build a custom gaming computer by where the customer individually chooses each component going into their computer, allowing them to specify exactly how they want their computer to run and perform.
  3. Memory: Memory is absolutely essential to system performance. Gaming computers are typically larger than standard PC?s, both in terms of literal size and in terms of memory. This memory is needed to cope with the copious amounts of data saved to ensure that a game can be replayed at the place it was last left.

Father of Boston bomb suspects plans U.S. trip to bury son

By Alissa de Carbonnel

MAKHACHKALA, Russia (Reuters) - The father of two men suspected of carrying out the Boston bombings said on Thursday he would travel from Russia to the United States to bury his elder son.

Anzor Tsarnaev and former wife Zubeidat Tsarnaeva, sitting side by side in the southern Russian city of Makhachkala, denied their sons had planted the bombs at the Boston marathon which killed three people and wounded 264, saying they had been framed.

Banging the table in front of him, Anzor said: "I am going to the United States. I want to say that I am going there to see my son, to bury the older one. I don't have any bad intentions. I don't plan to blow up anything.

"I am not angry at anyone. I want to go find out the truth," said Anzor, who took off his sunglasses only when photographers asked him to.

He said he would go as soon as possible but that he had not yet bought a plane ticket.

Zubeidat Tsarnaeva, her face pinched under her black head scarf, criticized the U.S. police for shooting dead Tamerlan Tsarnaev, 26, four days after the bombing.

The other son Dzhokhar, 19, was wounded and captured after a manhunt. He is in a fair condition in hospital and is charged with two crimes that carry a possible death penalty.

"I wanted to scream to the whole world, 'What did you do?' What have you done with my son? He was alive. Why did you need to kill him? Why didn't you send him to Guantanamo or whatever? Why? Why? Why did they have to kill him? They got him alive, he was in their hands," she shouted, her voice cracking.

"It is some kind of show, spectacle," she said in accented English.

She recounted how she had called Tamerlan after the bombing and he had told her not to worry.

"There is a lot that is unexplained," she said, adding that she was considering giving up her U.S. citizenship.

The Tsarnaev family lived in Makhachkala, the capital of the restive Dagestan region in Russia's volatile North ?aucasus, more than a decade ago before emigrating to the United States.

Anzor and Zubeidat later returned to Russia and their two sons remained in the United States, although Tamerlan came to Dagestan during a six-month stay in Russia last year.

Samsung continues on U.S. warpath as Best Buy micro-stores roll out

WARSAW, April 25 (Reuters) - Borussia Dortmund striker Robert Lewandowski played down his stunning one-man demolition of Real Madrid, saying he had played better than Wednesday's four-goal masterclass. The Poland international scored all his team's goals in a 4-1 win over the nine-times champions in their Champions League semi-final first leg. "In the second half Real Madrid did not know how they should play, at some moments they were helpless," Lewandowski told the Polish pay-TV platform nc+. "We took the first step (towards the final).

Options exchange reopens after half-day outage

(AP) ? Trading on the biggest exchange for financial options resumed Thursday following an outage caused by software problems.

The Chicago Board of Options Exchange failed to open at its regular time of 9:30 a.m. Eastern, then reopened at 12:50 p.m. with trading of options on the Standard & Poor's 500 index, according to CBOE spokesperson Gail Osten.

Trading of other options resumed ten minutes later, according to the CBOE's Twitter feed.

Options give the holder the right, but not the obligation, to buy and sell stocks or other financial assets.

The CBOE is the largest U.S. options exchange. Many of the most frequently-traded stock options are bought and sold on its exchange.

HTC insists Nokia's injunction won't affect the One's current stock, new mics in the works

HTC Nokia's injunction doesn't apply to the One

In an email to press, HTC took the opportunity to make a few clarifications about the injunction filed by Nokia this week regarding the dual-membrane microphone in the One. The preliminary injunction claims that the high-amplitude mic, which HTC uses in its flagship device, was supposed to be manufactured exclusively for the Finnish company (and currently used in the Lumia 720). If you've been wondering how this particular action would affect sales of the high-end HTC handset, spokespeople assure us that it's business as usual for the company. According to its official statement, the One is not the actual target of any injunction in The Netherlands -- in actuality, the legalities of the matter are apparently only between Nokia and STMicroelectronics, the supplier of the component in question.

HTC tells us that Nokia's attempts to institute a recall of the One failed; since the products were purchased in good faith, the ruling states that HTC can continue to use microphones that are in its inventory. Despite having a history rich in manufacturing delays, we're told that this legal ruling will have no effect on the One's availability. The Taiwanese phone maker plans a transition to "improved microphone designs" as soon as its current stock of STM supplies has been exhausted, a move which HTC claims will be transparent to consumers. Head below to see the full statement.

'Urgent need' to remove space debris

There is now so much debris in orbit that the space environment is close to a cascade of collisions that would make space extremely hazardous, a major international meeting has concluded.

Its summary position stated there was an "urgent need" to start pulling redundant objects out of the sky.

Scientists estimate there are nearly 30,000 items circling the Earth larger than 10cm in size.

Some are whole satellites and rocket bodies, but many are just fragments.

These have resulted from explosions in fuel tanks and batteries, and from the high-velocity impacts between objects.

Upwards of 10cm is trackable with radar, but there are tens of thousands more pieces that are smaller and move unseen.

Continue reading the main story

?Start Quote

Only active removal of five to 10 large objects per year can reverse the debris growth?

End Quote Prof Heiner Klinkrad Esa Space Debris Office

And it is the prospect of an increase in the frequency of catastrophic collisions among all this material that now worries the experts.

"There is a consensus among debris researchers that the present orbit debris-environment is at the rim of becoming unstable within a few decades, a phenomenon that is commonly known as the Kessler Syndrome, and that only active removal of five to 10 large objects per year can reverse the debris growth," Prof Heiner Klinkrad, the head of the European Space Agency's (Esa) Space Debris Office told reporters.

Prof Klinkrad was the chairman for the 6th European Conference on Space Debris in Darmstadt, Germany.

Insufficient compliance

The meeting was presented with a study earlier in the week that suggested the population of objects in low-Earth orbits (LEO) - the important altitudes used by imaging spacecraft to health-check the planet - would likely rise steadily over the next 200 years even under the most optimistic of scenarios.

The research highlighted the need for better adherence to best-practice guidelines.

These "rules" call on space operators in LEO to make sure their equipment naturally falls out of the sky within 25 years of the end of a mission.

But compliance with the guidelines is far from perfect, and the panel said active removal was now the urgent topic on the agenda.

Quite how much time there was to act before conditions became intolerable was not yet clear, said Christophe Bonnal from the French space agency (Cnes).

"We say we want to 'stabilise' the environment. Does that mean we are satisfied with today's situation? Could we live with a situation that is two times worse than today, or do we need to decrease [the debris population]? These are questions which are ongoing at international level," he told BBC News.

Active removal would see new spacecraft launched specifically to take other, redundant satellites out of orbit. And the Darmstadt meeting was presented with an array of concepts that included the use of nets, harpoons, tentacles, ion thrusters and lasers.

The conference summary panel told the media it was vital that pilot programmes were implemented to advance these technologies.

Commercial barrier

A few have been approved. The German Space Agency (DLR) is developing a project called DEOS that would demonstrate the robotic capture of a tumbling object in space.

"In this mission, what we want to show is that it is technically possible to safely approach a satellite, which we launch together with our main satellite, to capture it by means of a robotic arm and to perform a number of services like repairing or maintenance operations," explained DLR's Dr Manuel Metz.

"Many of the technologies which are currently being developed for DEOS would be useful for potential future international active debris-removal missions."

The experts also stated that the international community needed to sort through the myriad legal issues that would currently frustrate attempts to clean up space.

At the moment, international law permits only the launching nation or agency to touch an object in orbit, something that would prevent, for example, commercial debris removal activities.

"My dream is that a new agency like the International Telecommunications Union will be proposed at UN level to coordinate all this activity," said Dr Claudio Portelli from the Italian space agency (Asi).

Costly mission

Esa was hosting this week's meeting. It has two old satellites in orbit that are likely to become targets for a future de-orbiting exercise.

ERS-1 and Envisat both suffered major failures that left them drifting uncontrolled through LEO.

The duo can be tracked but nothing can be done to move them off a potential collision course, should one arise.

Envisat in particular is considered a high priority for removal because of its great size - over eight tonnes.

However, de-orbiting this dead satellite would probably be very expensive. And the robotic spacecraft sent up to bring Envisat down would itself be very large.

Prof Klinkrad explained: "If you want to have a controlled de-orbit - and this is what you should have for Envisat because large portions are going to survive to ground impact - then you should have a highly energetic chemical propulsion system, and to reliably de-orbit Envisat from its altitude you'd need, I'd say, about 6% of its mass in terms of fuel.

"With everything included, you are talking about a two-tonne-type spacecraft [to do the de-orbiting]," he told BBC News.

To date, there have only been a handful of major collisions in orbit involving the largest objects.

Perhaps the best known was the 2009 impact between the defunct Russian Cosmos 2251 spacecraft and the American Iridium 33 satellite. The collision produced over 1,500 trackable fragments, many of which continue to pose a threat to operational missions.

Nottingham-China research collaboration holds hope for bovine and human TB vaccine

Nottingham-China research collaboration holds hope for bovine and human TB vaccine [ Back to EurekAlert! ] Public release date: 24-Apr-2013

Scientists at The University of Nottingham are studying whether harmful bacteria found in cattle could be harnessed to protect livestock from the devastating disease bovine tuberculosis (TB).

The research, being led by Professor Paul Barrow in the University's School of Veterinary Medicine and Science, could offer an important step towards developing a vaccine against bovine TB, which affects tens of thousands of cattle every year.

The study will investigate the disease in UK and Chinese cattle in collaboration with Professor Xiangmei Zhou at Beijing's China Agricultural University. The two-year project has been funded with a 200,000 grant from the Research Councils UK (RCUK) and Chinese Ministry of Science and Technology (MoST) China-UK Cooperation Programme in Global Priorities.

Professor Barrow said: "We have discovered very interesting and novel interactions between different bacterial types during mixed infections. One bacterial type can stimulate short term immunity against unrelated bacteria providing a degree of protection. We want to look to see if a similar relationship occurs between the bovine tubercle bascillus and other bacteria which are present in the tissues at the same time."

Bovine TB is a bacterial disease that in 2011 resulted in the slaughter of approximately 25,000 cattle in England at a cost of more than 90 million. Recent figures released by Defra show that the slaughter of cows increased by 10 per cent in 2012, with more than 38,000 animals being destroyed. In an effort to control the disease, the Government has introduced the bovine TB eradication programme including the proposed cull of badgers which have been found to be carriers of the disease.

In China, bovine TB is now a major economic problem, causing hardship for farmers and their families living in rural communities. In any one herd, up to 70 per cent of cattle can be affected.

Bovine TB is also a zoonosis an infectious disease that can cross the species barrier to spread from animal to human. In the UK, early detection means the disease is never allowed to reach the point where it can threaten human health. However, in China some spread of the bacterium which is the origin of the disease, Mycobacterium bovis, does result in some human tuberculosis. TB is a chronic disease that eats away at the lungs over a long period of time, eventually leading to breathing difficulties. Effective treatment can take up to two years, which is not a practical or financial option for impoverished people often living in remote locations.

The Nottingham scientists will be investigating whether being infected by other related bacteria could offer a protective effect against bovine TB. In particular, they are looking at another common cattle bacterium called Mycobacterium paratuberculosis, which causes the gut wasting condition Johne's Disease and has been tentatively linked with Crohn's disease in humans.

The researchers will be using advanced microarray technology to test samples from cattle from both the UK and China to detect the mixture of bacteria that may be present in a single animal. Colleagues in China will be conducting in vitro assays in cell culture to study whether the presence of one bacterium may affect the immune system in response to another.

The research could potentially lead to the development of an emergency vaccine that could be used to stimulate rapid resistance to bovine TB in the event that infection is found within a herd. Similarly, the application could also apply to humans, with family members being vaccinated quickly after the diagnosis of TB in a close relative.

Professor Wang Tao, Vice-President of the China Agricultural University said: "China Agricultural University and University of Nottingham signed a Memorandum of Understanding in 2011. Since then, the two universities have paid frequent visits to each other to promote a proposal of strategic partnership.

"Last year, both sides invested seed funding to encourage joint research in the three key areas of veterinary medicine, food security and biomass. We are excited to see a positive step forward that the young scientists of both universities have made in the platform.

"As one of the projects sponsored by CAU-UoN seed funding, this is the first achievement in concrete collaboration between the two universities. I believe it will lead our future into more productive cooperation in research, teaching and faculty & student exchange."

Professor Hai-Sui Yu, Pro-Vice-Chancellor (International) at The University of Nottingham, said: "We regard our partnership with CAU as a strategic one as such significant internal funding from The University of Nottingham has been used to pump-priming world-class research collaborations with CAU. I'm delighted that one of the projects that we supported internally has secured prestigious external funding."

TDK ST750


TDK continues to bring quality headphone?options to the world, the latest being the intriguing TDK ST750. Its alluring leather and metallic design houses a unique feature?an internal, battery-driven amplifier that makes the audio performance louder and more bass-heavy when powered-up. The $249.95 (list) headphones also work in passive mode, but in both modes, the audio leans toward a brighter, crisper sound that should appeal to purists more so than bass fiends.

Design
The ST750 sports a refined look, with black leather lining the headband and the edges of the earcups. The heavily cushioned black earpads and underside of the headband make for a very comfortable, lightweight fit, even over longer listening sessions. Each side incorporates the TDK logo on a brushed metallic surface. Inside the circumaural (around-the-ear) earcups, 40mm dynamic drivers bring intense audio when the power switch on the right earcup is on. The right side also houses the battery compartment?the ST750 requires two AAA batteries for powered operation.

Unfortunately, the cable is not detachable. Many current competing models now feature removable cables and often come with two (one is usually armed with an inline remote and microphone). It's not a deal-breaker, but at this price, it would've been a smart design addition. The ST750 has no inline remote or mic to speak of, and the cable itself has a tendency to stay wound and rigid, unlike many of the cloth-bound or flat cables we see on high-end headphones. The headphones themselves look and feel great, but the cable is a weak point of the design.TDK ST750 inline

The ST750 ships with two AAA batteries, a shirt clip, and a black cloth drawstring carrying pouch.

Performance
It should be noted that while the ST750 has an internal amplifier to boost volume and bass response, these headphones sound pretty solid without the power?they just don't get super loud. In passive mode, their sound signature is close to flat, but spiked a bit with bright, crisp highs. The bass response is steady and clean, nothing booming.

With the batteries in and the power on, however, these headphones get very, very loud. They also do not distort at top volumes, even on tracks with intense sub-bass content, like the Knife's "Silent Shout." Some headphones manage not to distort on tracks like this by simply not delivering the very deepest bass frequencies, but the TDK ST750 does indeed deliver deep low-end, it just doesn't boost the lows dramatically.

On Jay-Z and Kanye West's "No Church in the Wild," the star is actually the mid-high and high frequency response?the kick drum loop's attack is crisp and punchy. Sub-bass synth hits that punctuate the beat are robust but not comically intense, while the vocals and other high-mid content take center-stage.

Bill Callahan's vocals on "Drover" are imbued with a nice treble edge that helps them stay in the forefront of the mix. This track can often sound muddy on bass-boosted headphones, but here, Callahan's vocals, as well as the guitars, remain bright and clear. And the low frequencies enhance the drums only subtly?there's not nearly as much thunder to their low end as you hear on the Velodyne vTrue, for instance. Occasionally, however, the vocals sound a bit too sibilant, on both this track and the Jay-Z/Kanye West track.

On classical tracks, like John Adams' "The Chairman Dances," the higher register strings and percussion steal the spotlight, and they also can sound a bit overly bright at times. The lower register strings are graced with a touch of added bass response, but nothing intense. At the end of the piece, large drum hits that can sound unnatural on bass-heavy pairs sound powerful and real here?just enough low-end presence to bring a little thunder, but nothing that sounds unnatural or amplified, as the drums do on heavy-bass options like the aforementioned vTrue headphones.

In the $250 price range, you have a few options that offer different sound signatures. The Yamaha PRO 400 has a clean bass response but focuses more on the midrange content than the highs. The Denon Urban Raver AH-D320, meanwhile, offers a far more intense bass response?not unlike the Velodyne vTrue. If all of these are out of your price range, the Editors' Choice Sennheiser HD 558 is a more affordable gem, with a balanced frequency response and plenty of power.

For the price, the TDK ST750 delivers two different experiences?the quieter, less bass-enhanced passive mode, and the powered-up, louder, bass-heavy active mode. The ST750 is quite unique, in that it's a headphone pair with a powered internal amp but no extra features like Bluetooth streaming or noise cancellation. Forgetting about this factor and focusing on the audio delivered itself, the ST750 still stands out as a powerful audiophile-friendly pair that errs on the side of brightness, not booming low-end, when it errs at all. It's light on accessories or extra features beyond the internal amp, but it offers solid, clean sound.

Health insurance goes mobile ? Bankrate, Inc.

What's the healthiest move you can make right now? Quit smoking? Of course. Watch your weight? Good idea. Work out occasionally? Can't hurt.

But if you really want to turn all those Mom-wise good intentions into actual results, your best health move may be to acquire a smartphone.

While health insurance companies, medical practitioners and the federal government nudge our medical infrastructure toward electronic health records and provider connectivity, Silicon Valley is rolling out the future of medicine with mobile apps that can save you money and make you healthier today.

Track your health insurance 'Simplee'

This month, a Palo Alto, Calif., startup unveiled Simplee, a free mobile app that enables you to carry your medical bills, outstanding claims and health insurance data on your Apple device when you visit the doctor, as well as pay your bill from your smartphone.

Having that information at her fingertips gave Simplee director of design Evelyn Wang a leg up when she went in for knee surgery recently. When the hospital demanded payment upfront, Wang was able to Simplee show them that she had already met her annual deductible, and hence didn't overpay.

Blue Button and MDRevolution

The feds offer their own version of a mobile "medical wallet" called Blue Button, which enables Medicare recipients and U.S. veterans to access, download and store up to three years' worth of personal health records onto their computer, tablet, smartphone and other mobile devices.

Dr. Samir Damani, a 37-year-old cardiologist in La Jolla, Calif., is more interested in health results than electronic records, however. In 2011, he rounded up the necessary IT folks and started MDRevolution, a first shot at combining mobile health tracking, genetic assessments and personalized coaching.

MDRevolution collects all your relevant health data upfront, including genetic risk factors, metabolic rate, even how fast you metabolize coffee, then uses proprietary software to design a personalized plan that includes how often and how much to work out, what to eat and what not to eat. The lab then monitors your workout remotely via fitness tracking and heart monitoring devices. Patients pay between $25 and $75 per month for the program.

A health coach in your hand

Integrative health/fitness programs are well-timed to take advantage of health care reform's patient-centered approach to medicine, which rewards doctors based on how well they keep patients healthy rather than simply by how many procedures they perform. Companies such as Healthrageous, Keas and ShapeUp are busy selling the idea of mobile health coaching to U.S. companies desperate to cut both their health insurance costs and losses due to absenteeism.

While this digital road to wellness is no doubt paved with good intentions, I can't help but wonder whether the health data that a remote lab collect today might one day prove costly tomorrow in the form of higher health insurance premiums.

Let's hope that the "doctor in a phone" comes with HIPAA-like privacy protections.

Facebook and romantic relationships

Apr. 23, 2013 ? A Western Illinois University faculty member who published a study about Facebook and narcissism last year has authored another study about Facebook and romantic relationships.

WIU Department of Communication Assistant Professor Christopher Carpenter, with his co-author Erin Spottswood (Cornell University), have authored, "Exploring romantic relationships on social networking sites using the self-expansion model," which will appear in the July 2013 journal issue of Computers in Human Behavior. According to Carpenter, in the study, the co-authors found the more past romantic relationships the participants had, the more interests they listed in their Facebook profiles.

"I predicted this relationship because other research suggested that part of romantic relationship development involves adopting new interests and behaviors from one's partner," he said. "I also found that people who report appearing in more photos with their partners on Facebook and who regularly tag their partner in their status updates tend to have closer romantic relationships."

In humans, the self-expansion model -- per a seminal study authored by State University of New York, Stony Brook, Psychology Professor Arthur Aron and Elaine Aron, author of the book, "The Highly Sensitive Person" -- asserts the desire to grow is a key motivation. One of the key sources of this need to expand one's self is derived from romantic relationships.

Carpenter said he studies humans' interactions on Facebook and social networks because the online networks offer a unique window into people's lives.

"We can't follow people around with a tape recorder getting a record of what they say all day. Facebook, on the other hand, offers us the chance to see one part of that record. We can see how often people interact with their romantic partners on Facebook, what they say to each other and how they present themselves on their profiles," he explained. "As for this specific study, I had read about self-expansion theory and I began wondering if we ever truly cut ties with someone when we break up. We might not see that person anymore, but when we develop a relationship with someone, we take on some of their interests and traits and, in many cases, hang on to them long after we break up. Facebook offered a unique way of examining the extent to which those traces of past relationships remain in our profiles."

Carpenter said the study's sample included 276 respondents who answered questions about their relationship histories and social networking sites uses, while a subset of the sample (149 participants) answered additional questions about their current romantic partners.

In addition to receiving wide media attention about his 2012 study, "Narcissism on Facebook: Self-promotional and Anti-social Behavior" (published in the journal, Personality and Individual Differences, March 2012), Carpenter served as an invited Oxford Union Society speaker on the motion, "This House Believes Social Media has Successfully Reinvented Social Activism," in England in May last year.

In N.M.desert, drone pilots learn new art of war

By Tabassum Zakaria

HOLLOMAN AIR FORCE BASE, New Mexico (Reuters) - The tide of war may be receding, as President Barack Obama is fond of saying, but U.S. military demand for unmanned drones and their remote pilots is growing.

Here in the New Mexico desert, the U.S. Air Force has ramped up training of drone operators - even as the nation increasingly debates their use and U.S. forces prepare to leave Afghanistan.

"Every combatant commander in the world is asking for these things. Down in Southcom, Africom, Pacom, they're all asking for these assets, so it is in very high demand," said Lt. Col. Mike Weaver, 16th Training Squadron commander at Holloman Air Force Base, referring to the military's Southern, Africa and Pacific commands.

Weaver is an example of a fighter jet pilot turned pilot of Remotely Piloted Aircraft, or RPA, as the Air Force insists on calling drones. He flew F-15 fighter jets over Iraq and, after those squadrons were drawn down, trained on drones and flew them over Afghanistan.

"With the growth of the RPAs being what it is, a fast-growing industry in the Air Force really, you've got pilots coming from all different walks of life to fill the shoes," Weaver, clad in a green flight suit, said in his office here.

The use of drones to target and kill individuals has become increasingly controversial, and lawmakers have questioned Obama's legal justifications for using them to kill militants overseas who are U.S. citizens.

Obama has promised more transparency and, officials say, he and CIA Director John Brennan are deciding whether to remove the spy agency from the drone business and leave it to the Pentagon.

"Things are moving in that direction - moving more of these (CIA) operations to the military," a U.S. official told Reuters.

On Tuesday, a Senate Judiciary subcommittee will hold a rare public hearing on the administration's drone policy.

The Holloman base is a 90-minute drive from El Paso, Texas, through desert and low-lying scrub, on a road where a handful of vehicles would be considered rush hour.

In this sparsely populated expanse near Alamogordo and the dunes of the White Sands Missile Range, the military has expanded training over the last four years on the MQ-1 Predator and MQ-9 Reaper aircraft made by General Atomics.

CLASS IN SESSION

At the Holloman "schoolhouse," there will be 678 pilot and sensor operator students for fiscal year 2013 that started in October, up from 136 in 2009, when training was done solely on the Reaper. About two years ago, the Air Force established a special category, 18x, for drone pilots who came into training having never flown a manned military aircraft.

Right up front, Weaver explains why pilots bristle at the use of the word drone, which in the Air Force refers to targets that pilots practice shooting down. "We do not like the name 'drones' because it has the connotation that it is this autonomous machine out there operating."

Drone pilots make up less than 10 percent of Air Force pilots, but the service says in recent years it has trained more pilots to fly drones than fighters and bombers combined - 350 drone pilots in fiscal year 2011 compared with a total of 250 fighter and bomber pilots.

RPA pilots have similar physical requirements as military pilots of manned aircraft and go through an initial flight training course on small civilian aircraft in Pueblo, Colorado, a Holloman spokeswoman said.

At the end of 2012 there were 1,280 active duty Air Force pilots flying drones, compared with 300 in December 2007. Other military services also fly a variety of unmanned aircraft.

Previously, "the top dogs went to F-15s, and that has since changed because there is no air war," Weaver said. "The fighter track is just not as popular as it used to be."

An 18x student gets over a year of training before flying a mission overseas, compared to two years training to become a fighter pilot. For already established military pilots the drone training is about 6 months, but it is not necessarily easier for them. "We've had guys with pilot wings wash out of this," Weaver said.

The Pentagon earlier this month scrapped a proposed new medal to honor drone pilots and cyber warriors after an uproar over a decision to rank it above some medals given to service members wounded or killed in battle.

Personnel who remotely fly the CIA's drones and press the trigger on the weapons also come from the military, but they operate under the authorities that govern the spy agency's covert operations, sources said on condition of anonymity.

Supporters of moving the program to the military say the CIA would then fully focus on intelligence gathering and analysis.

Any shift would occur gradually, to iron out issues such as whether the CIA should continue conducting drone strikes in the tribal areas of Pakistan, which is not a declared war zone.

The military uses drones for missions such as providing air cover for ground troops, striking enemy snipers, or detecting homemade bombs. Fresh footprints or other disturbances in remote areas can be detected by comparing images captured by drones.

MORE BASES

Until 2009 all U.S. military drone operations were conducted from Creech Air Force Base in Nevada, but now they have spread to Cannon, Ellsworth, and Whiteman Air Force bases, located in New Mexico, South Dakota and Missouri, respectively. The aircraft take off from bases in the regions where they operate.

Training at Holloman started in 2009. Italian and British militaries send students to the training center, and the French and Germans have also shown an interest.

It takes a two-member crew to operate a drone: a pilot, who is an officer, flies the plane and launches the missile, and a sensor operator, who is enlisted, directs the camera equipment. Crews work in shifts because the drones can fly for 14-24 hours.

The lethally named Predator and Reaper aircraft look like silver-hooded flying reptiles with a sensor sphere under the "head" that operates as the eyes.

The "cockpit" from which the aircraft is flown is in a tan trailer with no windows and two giant air-conditioning hoses pumping air to cool the computers. On the Holloman base, the trailers are behind their own fenced area with razor wire and access restricted by a combination lock.

Inside the trailer, two chairs face about a dozen screens in total, including some that can tap into top information classified as secret and top secret. The feel is of an isolation chamber, with no outside distractions.

"This is a sterile cockpit environment," Weaver says. There is even a special knock if someone wants to enter.

A pilot who previously flew manned jets said she wished the drones offered a broader view, like the cockpit of a manned plane so the surrounding area could be seen. "Now I look at the ground all the time," she said, requesting her name not be used.

Weaver said the job is definitely not like playing video games. "You see (targets) running and you can hear them sometimes, the fear in their voice. It's not a video game."

Hagel: US committed to Israel's military edge

TEL AVIV, Israel (AP) ? U.S. Defense Secretary Chuck Hagel is assuring Israel that the Obama administration is committed to preserving and improving the Jewish state's military edge in the Middle East.

Hagel made the pledge at a news conference Monday at Israel's ministry of defense in Tel Aviv.

Hagel says the U.S. will permit Israel to buy various new weapons, including U.S. missiles and advanced radars for its strike aircraft.

Hagel also reiterates that the United States will leave it to Israel to decide whether and when it needs to attack Iran to stop it from building a nuclear bomb.

World finance leaders say growth still weak

WASHINGTON (AP) ? While world finance leaders say the global economy has improved slightly this year, they said the outlook for the future was uneven with growth and job creation still too weak.

The policy-setting committee for the 188-nation International Monetary Fund said governments need to act decisively to nurture a lasting recovery and restore the resiliency of the global economy.

But the major economies could not reach a consensus on what policies to follow as they move forward.

"The commodity that is in shortest supply now is confidence," Tharman Shanmugaratnam, the chairman of the IMF panel and Singapore's finance minister told reporters. "We need to regenerate optimism and confidence."

The World Bank announced that its steering committee had approved a proposal to establish the goal of eliminating extreme poverty by 2030. The bank defines this condition as living on less than $1.25 a day. The bank estimates there are 1.2 billion people living in extreme poverty, mainly in sub-Saharan Africa and south Asia.

A spokeswoman for Oxfam , the anti-poverty group, Emma Seery, said while the World Bank target was welcome "we are concerned that it will duck the tough choices needed to reach it."

The weekend began with two days of discussions among finance leaders of the Group of 20 nations, composed of major economies such as the United States, Germany and Japan and fast-growing developing nations like China, Brazil and India. The meetings of the IMF and its sister lending institution, The World Bank, followed.

The finance ministers tried to show they were cooperating even though they did not resolve differences that surfaced after an initially flawed bailout of Cyprus in March. The banking troubles on the Mediterranean island renewed fears that a prolonged European debt crisis still posed risks to the global economy.

The U.S. urged European nations to scale back their austerity programs of spending cuts and tax increases in favor of more stimulus to boost growth and combat high unemployment in countries such as Spain and Greece.

But the push was met with resistance from Germany and Britain, which believe heavily indebted European nations must reduce their debts to give markets confidence and keep government borrowing costs low. In the end, the financial leaders sought to bridge the difference by issuing economic blueprints that left room for both the growth and austerity camps to claim victory.

The G-20 nations did reject proposals to issue hard targets for reducing budget deficits, a victory for the United States and Japan, which had argued for more flexibility.

Middle school students from rural Maine will present a poster at the Experimental Biology 2013 conference detailing how their involvement with the Aspirnaut science-outreach program led to them becoming active scientific researchers.

Students from the Dedham School in Dedham, Maine, were participants in the Aspirnaut program (http://www.aspirnaut.org), a science-outreach program started at Vanderbilt University, in which scientists engage with middle- and high-school students through videoconferencing. Showing a great interest in the research that was being demoed by Vanderbilt scientists, four talented Dedham students volunteered to become part of the research project. Guided by their teacher and Aspirnaut organizers, the students worked to corroborate and expand on the discovery of a novel chemical bond found in animal tissues. Their research found that this bond, which they describe as an "essential innovation for the genesis of animal tissues," was also present in another lineage of multicellular organisms, thus demonstrating its evolutionary importance. This novel discovery will be included in a soon-to-be published scientific article.

After their discovery, the students made great efforts to inform members of their community about their research and its implications, thereby bringing the outreach effort full circle. The students will be at the Experimental Biology conference to talk about their experiences and how the Aspirnaut outreach program got them interested and involved with science.
