As South Korea and US end military drills, how will North Korea react?

Many Korea watchers speculated that once joint military drills ended, so would increased tensions with North Korea. But at least one analyst says this might the moment the North lashes out again.?

The US-South Korea annual military exercises ended without incident on Tuesday, perhaps allowing a chance for weeks of tensions on the Korean peninsula to enter an indefinite period of calm.

The annual military defensive exercises are intended to act as a deterrent to North Korea through shows of military prowess.?North Korea, however, called the two month-long exercises an aggressive invasion threat and promised military retaliation if provoked directly.

But now that the exercises are over, the North could tell its people that its own military successfully warded off the threat, conceivably allowing it enter dialogue with the South without appearing to lose face.?But some analysts argue that as the general atmosphere has cooled, action by North Korea could actually be more likely.

?Now that the exercises are over, this is an opportune time for a missile launch,? says Sung-yoon Lee, professor at the Fletcher School of Law and Diplomacy, Tufts University. ?Now that their adversaries have their guard down, they could go ahead with a launch now, ahead of the upcoming summit between Obama and Park Geun-hye, to put pressure on Park.?

South Korean President Park Geun-hye, who was inaugurated on Feb. 25, is scheduled to meet with US President Obama in Washington on May 7. North Korea has been known to purposely raise tensions in an effort to rattle new administrations in Seoul or Washington.?

"The drill is over, but the South Korean and US militaries will continue to watch out for potential provocations by the North, including a missile launch," said Kim Min-seok, a spokesperson for South Korea?s Ministry of National Defense.

The two-month long exercises started up shortly after the North's third nuclear test in February and involved around 10,000 US troops and 200,000 South Korean forces. Throughout the exercises, some impressive weaponry was shown off, including B-52 bombers and a nuclear-armed submarine. After the exercises began, the North announced it was scrapping an armistice agreement that effectively put the Korean War on hold, and said it was?entering a "state of war." The North also cut two hotlines to South Korea, symbols of North-South cooperation, but left a joint economic region alone until April.?

The jointly-operated Kaesong industrial park, the last major symbol of cooperation between South and North?was designed to economically benefit both sides, providing South Korean companies with cheap labor, and North Koreans with much needed income. Since it was started in 2004, it has survived years of chilly inter-Korean relations.?

But North Korea unexpectedly barred South Koreans from entering the area early in April and then withdrew all its workers shortly thereafter. Though some South Korean workers stayed at the complex, many went back to South Korea.

The situation at Kaesong is one aspect of the crisis that appears set to continue.

Yesterday, 43 of the final 50 South Korean workers in Kaesong returned home. Seven stayed behind to deal with some unpaid wages, as North Korea has not approved their departure yet, according to Chosun. There is not yet any indication that Seoul and Pyongyang will cooperate in finding a way to get operations at the complex back underway. The complex brought in about $80 million in revenue for North Korea in 2012, so there is a large financial incentive for the North to restart business there.?

Today South Korean Minister of Unification Ryoo Kihl-jae said that while the South is interested in restarting operations at Kaesong, Seoul wouldn?t accept just any conditions demanded by North Korea.

"It is pointless to normalize operations at the Kaesong Industrial Complex if it entails accepting unreasonable claims and preconditions," Minister Ryoo said.

All throughout the war games, many analysts speculated that North Korea?s intention was to stir tensions and pull back at the last minute from any kind of engagement in an effort to strengthen its bargaining position when it returns to the table at some later date.?

?The general principle is to escalate tensions in order to later be able to negotiate from a position of strength,? Leonid Petrov, a researcher in Korean studies at Australian National University, told the Monitor on Apr. 10.

WATERLOO, Ont. (Monday, April 29, 2013) Researchers at the University of Waterloo have found that children hear more complex language from parents when they read a storybook with only pictures compared to a picture-vocabulary book. The findings appear in the latest issue of the journal First Language.

"Too often, parents dismiss picture storybooks, especially when they are wordless, as not real reading or just for fun," said the study's author, Professor Daniela O'Neill. "But these findings show that reading picture storybooks with kids exposes them to the kind of talk that is really important for children to hear, especially as they transition to school."

The study, by Professor O'Neill of the Department of Psychology at Waterloo, and Angela Nyhout, a graduate student, recorded 25 mothers while they read to their toddlers both a wordless picture storybook and a vocabulary book with pictures.

"What we found was that moms in our study significantly more frequently used forms of complex talk when reading the picture storybook to their child than the picture vocabulary book," said Professor O'Neill.

The researchers were especially interested in looking at the language mothers use when reading both wordless picture storybooks and picture vocabulary books to see if parents provided extra information to children like relating the events of the story to the child's own experiences or asking their child to make predictions.

"So, when reading the picture story, we would hear moms say things such as 'where do you think the squirrel is going to go?' or 'we saw a squirrel this morning in the backyard.' But we didn't hear this kind of complex talk as often with vocabulary books, where mentioning just the name of the animal, for example, was more common, " said Professor O'Neill.

The results of the study are significant for both parents and educators because vocabulary books are often marketed as being more educational. "Books of all kinds can build children's language and literacy skills, but they do so perhaps in different ways," said Professor O'Neill. "It's exciting to find that even short wordless picture books provide children with exposure to the kinds of sophisticated language that they will encounter at school and that lay the foundation for later reading development."

A Research Development Initiative grant, which the Social Sciences and Humanities Research Council of Canada awarded to Professor O'Neill, supported this research.

Nest thermostat gets summer-savvy tweaks in update

Summer is inbound, at least for those in the northern hemisphere, and with it comes big temperature swings, humidity, and other problems. The Nest smart thermostat ($249) is getting ready with a few new features that should keep your home cool and dry.

First, the Nest will now use its light sensor to detect when it is in direct sunlight and adjust its readings accordingly. Sun can throw off a thermostat's readings and cause the air conditioning to run amok, but the new Sunblock features should prevent that from happening.

Fan-lovers will be happy to hear that new advanced fan controls are coming as well: Turn on the fan just for a few minutes every hour to circulate the air, or have them run all night for a cool breeze.

In extremely humid areas vulnerable to mold, the Nest will now run the A/C to dry things up a little. Nobody likes coming home to a muggy house. The mobile app will also now let you know when you need to change a filter or if something isn't working correctly.

Lastly, the "Auto-Tune" feature was recently updated to make special summer allowances, avoiding running energy-intensive appliances during peak hours and so on.

No need to install anything ? if your Nest is connected to your Wi-Fi, it should update itself on its own. More details on the features and instructions on activating them are at the blog post announcing the update.

Wall Street Week Ahead: Central banks, data to steer investors

By Wanfeng Zhou

NEW YORK (Reuters) - With signs of a slower economy mounting, the near-term outlook for U.S. stocks isn't rosy, but investors may find comfort next week from the world's major central banks.

The Federal Reserve will meet on Tuesday and Wednesday, with the report of weaker-than-expected, first-quarter growth could reinforce expectations the Fed will keep purchasing bonds at a pace of $85 billion a month.

Low interest rates and ample liquidity provided by the Fed and other central banks have buoyed global equity markets because low borrowing costs for businesses and consumers lead to richer corporate profits. Major U.S. stock indexes hit record highs earlier this month.

"As long as it looks like central banks are on your side and on investors' side as far as providing more liquidity, that's going to help improve sentiment," said Brian Jacobsen, chief portfolio strategist at Wells Fargo Funds Management in Menomonee Falls, Wisconsin.

"I don't think (Fed officials) have got enough data since the last meeting to really justify changing policy. I really don't think they're going to look at slowing the pace of purchases until probably September."

A strong commitment from the Fed to continue its stimulative policy, coupled with corporate earnings that have mostly exceeded lowered forecasts, could help Wall Street extend a rally despite signs that the U.S. economic recovery is losing momentum.

Even though the market ended flat on Friday, its performance for the week was positive. The Standard & Poor's 500 rose 1.7 percent, the Dow Jones Industrial Average was up 1.1 percent and Nasdaq Composite Index rose 2.3 percent

The economy expanded at a 2.5 percent annual rate in the first quarter, the Commerce Department said on Friday, short of expectations of 3.0 percent and setting a cautious tone.

A heavy slate of key economic indicators will be released next week, including personal income and spending, the Institute for Supply Management's manufacturing and services activity indexes, pending home sales, the Chicago purchasing managers' index and consumer confidence from the Conference Board.

The highlight of the week will come on Friday when the Labor Department releases its employment report for April.

Economists polled by Reuters are looking for job growth of 150,000, up from 88,000 in March. The unemployment rate is likely to remain unchanged at 7.6 percent.

"Today's (GDP) data suggests maybe the momentum is much weaker that what was priced in," said John Praveen, chief investment strategist at Prudential International Investments Advisers in Newark, New Jersey.

"We have had a very strong rally, so people are looking for any trigger for profit-taking," he said. Praveen said the market could see a 5 percent pullback in the months ahead should upcoming data prove weaker than expected.

Stocks have had a wild run over the past week after hackers attacked the website of stock broker Charles Schwab Corp and a false report on the Associated Press's Twitter account about explosions at the White House sent the market into a brief tailspin.

On Thursday, a software glitch shut down the Chicago Board Options Exchange for half the day, preventing trading in options on two of the stock market's most closely watched indexes and delivering the latest blow to confidence in the way U.S. financial markets operate.

EUROPE, EARNINGS

The European Central Bank meets on Thursday and investors will watch to see if it delivers an interest-rate cut as the euro zone economy deteriorates further. Further monetary easing would encourage investors to buy riskier assets and boost stocks.

"The market has been rallying on the fact the ECB might actually start to do something; if the U.S. market reacts in the same way, that might get the market rallying," said John Canally, investment strategist and economist for LPL Financial in Boston.

With earnings reporting now half over, investors will look to see if companies can continue to exceed profit estimates despite lackluster revenue.

According to Thomson Reuters data, of the 271 companies in the S&P 500 that have reported earnings for the first quarter, 69 percent have beaten analysts' expectations, above the 63 percent average since 1994.

However, only 43.9 percent have topped analysts' revenue forecasts, well below the 62 percent average since 2002 and the 52 percent rate for the last four quarters.

Analysts now see earnings growth of 3.8 percent this quarter, up from expectations of 1.5 percent on April 1.

Next week Dow components reporting results will be Pfizer and Merck . Other companies scheduled to report include Loews Corp , Aetna Inc , Chesapeake Energy , Visa Inc , Viacom Inc and Kraft Foods Group Inc .

David Joy, chief market strategist at Ameriprise Financial, based in Boston where he helps oversee about $700 billion in assets, said the lackluster figures suggest the second quarter may not be as robust as hoped.

"Right now, markets are going through an adjustment process, trying to figure out just how robust the economy is here and overseas as well," Joy said. "You have investors sort of biding their time. They are invested, but not with complete conviction."

Millions in CIA "ghost money" paid to Afghan president's office: New York Times

(Reuters) - Tens of millions of U.S. dollars in cash were delivered by the CIA in suitcases, backpacks and plastic shopping bags to the office of Afghanistan President Hamid Karzai for more than a decade, according to the New York Times, citing current and former advisers to the Afghan leader.

The so-called "ghost money" was meant to buy influence for the Central Intelligence Agency (CIA) but instead fuelled corruption and empowered warlords, undermining Washington's exit strategy from Afghanistan, the newspaper quoted U.S. officials as saying.

"The biggest source of corruption in Afghanistan", one American official said, "was the United States."

The CIA declined to comment on the report and the U.S. State Department did not immediately comment. The New York Times did not publish any comment from Karzai or his office.

"We called it ?ghost money'," Khalil Roman, who served as Karzai's chief of staff from 2002 until 2005, told the New York Times. "It came in secret and it left in secret."

For more than a decade the cash was dropped off every month or so at the Afghan president's office, the newspaper said.

Handing out cash has been standard procedure for the CIA in Afghanistan since the start of the war.

The cash payments to the president's office do not appear to be subject to oversight and restrictions placed on official American aid to the country or the CIA's formal assistance programs, like financing Afghan intelligence agencies, and do not appear to violate U.S. laws, said the New York Times.

There was no evidence that Karzai personally received any of the money, Afghan officials told the newspaper. The cash was handled by his National Security Council, it added.

U.S. and Afghan officials familiar with the payments were quoted as saying that the main goal in providing the cash was to maintain access to Karzai and his inner circle and to guarantee the CIA's influence at the presidential palace, which wields tremendous power in Afghanistan's highly centralized government.

Much of the money went to warlords and politicians, many with ties to the drug trade and in some cases the Taliban, the New York Times said. U.S. and Afghan officials were quoted as saying the CIA supported the same patronage networks that U.S. diplomats and law enforcement agents struggled to dismantle, leaving the government in the grip of organized crime.

In 2010, Karzai said his office received cash in bags from Iran, but that it was a transparent form of aid that helped cover expenses at the presidential palace. He said at the time that the United States made similar payments.

The latest New York Times report said much of the Iranian cash, like the CIA money, went to pay warlords and politicians.

For most of Karzai's 11-year reign, there has been little interest in anti-corruption in the army or police. The country's two most powerful institutions receive billions of dollars from donors annually but struggle just to recruit and maintain a force bled by high rates of desertion.

Recording studio in Newcastle: What makes a good facility? - Artipot

Finding a recording studio in Newcastle isn't a difficult job as there are many but you have to choose a facility according to your needs so that you get what you want. For instance take a home based facility. This facility would work well, if your needs are limited and you have just one project to complete. But if you want to work on many projects then you should locate a professional facility.

Could a home based facility be a professional facility? Yes it could, provided it has all the equipments required for producing different beats. The facility should be managed by experienced musicians that understand the needs of their clients. There are many factors to consider other than cost or the service charge of the facility. If price matters most then you should look for a home based facility because home studios charge much less than their commercial counterparts.

Start with determining your needs. If you know how to play music instruments and produce musical sound beats then you could manage to complete your project in a substandard facility. But if you are looking for professional assistance by experienced sound engineers then you should look for a commercial facility, where you have access to everything from necessary equipments to sound mixing software.


How much a facility would charge? Here you can't do a comparison between the service charge of a home based facility and a commercial studio because former charges much less than latter. But you could do a comparison between two home based facilities. Do an online search and find some home based studios located close to your home. Pay a visit to the facilities to know their services. If you are satisfied with the services, a home based recording studio in Newcastle is offering, you could go ahead and search more facilities.

Before choosing a home based facility, do a quality comparison between former and a professional recording studio in Newcastle. Look at the quality of services of both the establishments and choose one that you find reliable. Also look at the suitability and convenience of both the facilities. In this way, you would be able to find a perfect studio.

Whether you are a singer, website designer or an ad maker, you could improve your business with the help of a professional recording studio in Newcastle. Your professional studio could be a home based facility or a commercial establishment. You should explore all the options.

How One Small Business Owner Sketched his Way to Success ...

Life?s greatest opportunities often rise from life?s greatest challenges (and even failures). That?s the story of so many small business owners, and that?s certainly the case with Mark Rivard, owner of Rivard Art LLC.

I first learned about Mark when I saw him tweet about packing and shipping some skateboard blanks at his local The UPS Store in Minneapolis. Shortly after, I spoke with Mark and learned more about his passion for art, how his business came to be, and, more importantly, what he?s doing to give back.

Growing up in Minneapolis, Mark?s passion was skiing. Though he had an interest in art, he humbly admits he wasn?t good at it. In fact, he almost didn?t graduate from high school because he was failing art class. How?s that for irony?

After high School, Mark moved to Colorado to pursue a career in the ski industry. After a few years there, Mark tore his ACL, MCL, PCL and meniscus while skiing and moved back home to recover.

A naturally active individual, Mark was confined to his home. One day, he grabbed one of his old skateboards and a Sharpie? marker and began sketching the Minneapolis skyline. But he didn?t stop there. He continued to sketch art on some 30 skateboards. Soon he was holding DIY art shows and traveling around the world talking to students and professionals about his skateboard art.

Check out more of Mark?s story below:

Owning your own business has many rewards. Mark says the most rewarding part of his experience isn?t selling his artwork ? it?s helping youth discover their passion for art.

Which brings me back to those skateboard blanks he was shipping. It turns out those were part of what Mark calls The Virginia Project, a project that took him to Lawrenceville, VA to teach skateboard art to the students at Brunswick High School. He spent several days teaching the students not only how to create skateboard art, but also how to share their artwork with those around them by holding art shows ? a model of how he got started as a skateboard artist and small business owner.

The Virginia Project is part of Mark?s Rivard Art Education program. To Mark, the art program allows students to see how they can apply art to their lives after they finish school, something he says he feels was really lacking when he was going to school.

Comment below and tell us about the moment when you discovered your passion as a business owner.

Knicks Rout Celtics 90-76 In Game 3: Carmelo Anthony Leads New York To 3-0 Playoff Series Lead (VIDEO)

BOSTON ? The New York Knicks want to finish their long road back to the second round quickly.

They haven't won a playoff series in 13 years, and now they have a shot to end this one in four games.

"Guys are hungry," forward Carmelo Anthony said. "We really want this, we feel like it's right there in the palm of our hands."

Anthony scored 26 points and the Knicks moved to the brink of a sweep, routing the Boston Celtics 90-76 on Friday night in Game 3 of the first-round series.

Quickly taking the crowd out of it in the first NBA game here since the Boston Marathon bombings, the Knicks built a 16-point halftime lead and now are on the verge of taking out the Celtics.

"That first quarter on the road, you've got to make sure you take that first punch and we did that," Knicks veteran Jason Kidd said.

Raymond Felton added 15 points and 10 assists for the Knicks, who haven't advanced in the playoffs since reaching the 2000 Eastern Conference finals. Game 4 is here Sunday afternoon.

They'll have to hope they have J.R. Smith, who inexplicably threw an elbow right into Jason Terry's face with 7:06 left and was thrown out of the game with a flagrant foul 2, an automatic ejection. The league office will review the play and can fine or suspend Smith.

Jeff Green scored 21 points for the Celtics, who will try to become the first NBA team to win a series after trailing 3-0. They own the most titles in league history, but their present looks extremely bleak.

"I didn't think we showed up not to play well," Celtics coach Doc Rivers said. "I thought overall our effort was there, I thought we did lose our spirit early on."

Fans cheered the responders who helped after the marathon but booed the Celtics, who managed only 31 points in the first two quarters, getting their bad half out of the way early this time. They had been held to 25 and 23 points after halftime while dropping the two games in New York.

Smith finished with 15 points for the Knicks, who are loaded with veterans who've had playoff success the franchise hadn't in recent years and weren't fazed by the pregame atmosphere. Once the game started, they simply outplayed the Celtics, as they have while going 6-1 against them dating the regular season.

"We came in here believing that we could win this basketball game and we did it," Anthony said. "It was a total team effort."

Everything went perfectly for the Knicks until Smith, while holding the ball on offense with a huge lead, decided to throw his elbow right into Terry's face. Terry charged after him but was stopped by Rivers, while Knicks coach Mike Woodson appeared to be lecturing Smith before the Sixth Man of the Year was sent off.

"He'll learn from it. I don't think he was trying to hurt the kid, I thought he was trying to clear space, but hey, they saw it differently," Woodson said. "I'm going to stay in his ear and make sure he learns from it."

There was a moment of silence before the game for the victims, and that was the last time it was quiet for a while. First responders and other personnel were greeted with loud cheers as they were brought onto the floor during timeouts, and a tribute to the city's strength played on the overhead video board during a first-quarter stoppage.

But the Knicks' dominance wore down even the most spirited supporters, just the way LeBron James did in his 45-point performance in Game 6 of last year's Eastern Conference finals in the last playoff game here.

Rivers said he was aware of some of his team's shortcomings, with the absence of Rajon Rondo leaving the Celtics without a point guard. But Rivers ? himself a former point guard ? couldn't have imagined his team would be this unable to get into an offense, finishing with 18 turnovers that led to 26 Knicks points.

He started Terry for forward Brandon Bass, trying to find a way to get another ball handler on the floor. But it couldn't fix the Celtics' shooting and didn't really help much with the ball handling, as Terry had his dribble taken right away from him on one third-quarter possession when Boston briefly looked ready to get back into it.

Paul Pierce and Kevin Garnett missed layups on the same possession to start the game, and it was clear right from there this wasn't the Celtics' night ? or their series.

"Right now at this point, just take it one game at a time," Green said. "They haven't won it yet."

Pablo Prigioni gave the Knicks a boost with three early 3-pointers as the Knicks positioned themselves to avenge their first-round sweep at the hands of the Celtics two years ago. Boston hasn't been by swept since 2004, by Indiana.

Garnett had 12 points and 17 rebounds, while Pierce missed six of his first seven shots and finished with 17 points.

The Celtics were within three early in the second quarter before Prigioni and Smith hit 3-pointers in an 8-0 run that made it 34-23. The Celtics had held Anthony in check until then, but he got hot late in the half while they remained ice cold.

Back-to-back jumpers had the defense keying on his jumper, so he spun toward the basket to catch an alley-oop pass, and Felton followed with a 3-pointer to make it 47-29 with 58 seconds left in the half. Green made a layup for the final basket of the half, then the Celtics walked off to boos.

Boston cut it to 49-38 and Terry was dribbling up the floor on a fast break when Prigioni stepped in and swiped the ball away from him. The Knicks missed a shot, but Prigioni grabbed the rebound to set up a 3-pointer by Anthony. Felton followed with another basket to make it 54-38, and Boston's momentum was gone for good.

The Knicks later led by as much as 21.

Boston has been held to 78, 71 and 76 points in the series.

Notes: The Knicks' last sweep of a best-of-seven series was when they beat Atlanta in the 1999 East semis. They swept Toronto in a best-of-five series in the first round the following year. ... Rivers, on being fined $25,000 by the NBA on Thursday for his criticisms of the officiating in Game 2. "Usually the way it works, once NBA security calls, they're not calling to tell you they love you," he said. "Listen, like I said to them, I didn't get fined for being wrong. I got fined for saying it."

It's generally understood that in the Fox News and Glenn Beck breakup, Fox was the dumper and Beck the dumpee. But, in most breakups where the couple shares a social circle, neither party wants a reputation as the dumpee. Beck says he's the one who wanted to leave -- because the network was so depressing.

Weight loss programs via virtual reality

Apr. 25, 2013 ? Weight loss is a topic of concern for nearly 36% of Americans who are considered obese. There are many barriers that can interfere with weight loss. For those attending face-to-face weight loss programs, barriers can include travel, conflict with work and home, need for childcare, and loss of anonymity.

In a new study released in the May/June 2013 issue of the Journal of Nutrition Education and Behavior, investigators from The University of Kansas Medical Center continue to explore alternative weight management delivery methods to eliminate some of these barriers. The solution they are investigating -- virtual reality for weight loss and weight maintenance.

Looking at the results from twenty overweight and obese individuals after 3 months of a weight loss program at a weekly clinic delivered via face-to-face or virtual reality and then 6 months of weight maintenance delivered via virtual reality, the investigators found virtual reality compares favorably with face-to-face for weight loss and may facilitate greater weight maintenance. Debra Sullivan, lead investigator, adds, "Although we found weight loss was significantly greater for face-to-face compared to virtual reality, weight maintenance was significantly better for virtual reality."

The virtual reality weight maintenance program was conducted using Second Life, a Web-based virtual reality environment available to the public. Participants in Second Life create virtual representations of themselves, called ''avatars,'' which can interact with other avatars and navigate through the virtual world of Second Life. Voice communication is accomplished via headset, which allows for person-to-person and group interaction. Education and training takes place on an ''island,'' which is purchased from Second Life and provides restricted group access to the nutrition education/training area.

To further explain how Second Life can be used in this capacity, Dr. Sullivan explains, "Individuals who want to participate in real-life scenarios without real-life repercussions can use virtual reality. For example, participants can practice meal planning, grocery shopping, and dietary control when eating at restaurants and holiday parties to a much greater extent with Second Life compared with the time-limited clinic meeting. Virtual reality may even be able to serve as a more feasible option to monitor individuals after completing a weight loss program."

Hormone levels and sexual motivation among young women

Apr. 25, 2013 ? Feeling frisky? If so, chances are greater your estrogen level -- and, perhaps, fertility -- are hitting their monthly peak. If not, you're more likely experiencing a profusion of desire-deadening progesterone, and the less fertile time in your cycle. Oh, the power of hormones.

Researchers have long suspected a correlation between hormone levels and libido, but now scientists at UC Santa Barbara, led by James Roney, a professor in the Department of Psychological and Brain Sciences, have actually demonstrated hormonal predictors for sexual desire. Their findings appear in the current issue of the journal Hormones and Behavior.

"We found two hormonal signals that had opposite effects on sexual motivation," said Roney, the article's lead author. "Estrogen was having a positive effect, but with a two-day lag. Progesterone was having a persistent negative effect, both for current day, day before, and two days earlier." When hormone levels and sexual desire were factored against the menstrual cycles of test subjects -- in this case, undergraduate students -- the researchers saw a measurable increase in progesterone levels at the same time the subjects noted decreases in sexual motivation. Progesterone, the researchers say, is mediating this drop in desire from the fertile window to the luteal phase -- the second half of the menstrual cycle.

"Progesterone acting as a potential stop signal within cycles is a novel finding in humans," noted Roney. "We know in rhesus monkeys there is a strong negative correlation with progesterone and a positive correlation with estrogen. The patterns are actually comparable to what you see in non-human primates, but hadn't been shown in humans."

The researchers' findings have potential implications on the treatment of low sexual desire and how hormone replacement trials are done. "We're not controlling hormones the way they do in the hormone replacement literature, so, in a sense, that literature is more directly applicable in terms of medical applications," said Roney. "But in the long run, it would be good to have a model of the combination of signals that operates in the natural cycle. The way hormone replacement trials are done now, there's no model of the natural signals, so they're sort of random -- let's give estrogen, let's give testosterone, let's combine them this way or that way."

Roney noted that his findings don't present a full model, and he'd like to replicate his results with women of different age groups. "Undergraduates might be unique for a lot of reasons," he said. "Their hormone levels tend to be a bit different from those of women even just a little bit older. And married women in their 30's are likely to be more consistently sexually active, and that might change the patterns in some ways. They also tend to have higher hormone secretion and more regular cycles than younger women," he said

Eventually, Roney continued, the goal would be to have a better model of the signals in a natural cycle that might then inform medical research.

Another interesting finding, according to Roney, was the impact -- or lack thereof -- of testosterone on the women's sexual motivation. "There's a common belief in the medical literature that testosterone is the main regulator of women's libido," he explained. "Doctors tend to believe that, though the evidence isn't that strong in humans. In the natural cycles, we weren't finding effects of testosterone. It wasn't significantly predicting outcomes."

Roney doesn't deny that testosterone does seem to have a positive effect in hormone replacement therapy, but suggests the effects may be pharmacological. "Testosterone has those effects if you inject it externally in women who are menopausal, and there are a lot of reasons that might be the case," he said. "For example, testosterone can be converted to estrogen through a particular enzyme. If you inject menopausal women with testosterone, it might be acting as a device that's delivering estrogen to the target cells. So the fact that it works doesn't necessarily mean it's an important signal in the natural cycle."

Digital Storm's Latest Gaming PCs Are Almost As Cheap As DIY

Every time I post a review of a boutique gaming PC, someone in the comments has to mention that they could build a similar machine themselves for less money. That's still true for Digital Storm's newly-launched Vanquish line of gaming PCs, but it's a narrow truth ? we're talking $20 to $60 narrow.

Digital Storm's more expensive systems can run upwards of $8,000. Those premium systems are for hobbyists with money to burn. Then there's the Bolt, a custom-engineered slimline system aimed at people looking to pay a premium for a small footprint.

The Vanquish line, as far as I can tell, is for people that just want a damn gaming PC. It's a box with a window that runs computer applications and games, the only concession to flash a pair of red LED lights in the bottom of the case. Inside there are name-brand components, exactly the sort of name-brand components you can purchase at a place like Newegg.com.

In fact, to prove their price point, Digital Storm went ahead and priced out each of the four Vanquish models as parts at the online retailer's website.

S

The low-end Vanquish is $38 more than parts. The high-end, which I've been trying out for the past week, is $58 more. That's $58 worth of assembly, testing, warranty and lifetime tech support. As far as I'm concerned, Digital Storm made its point right there. I don't even know why I was sent a system to try out for the past week. Maybe they wanted me to make a video.

Not quite as comprehensive and informative as their own, but I'm just a guy sitting in front of a computer desk, asking it to love me.

S

I could discuss performance, noting that the Intel Core i7 3770K 3.50 GHz processor and the Nvidia GeForce GTX 6600 Ti, while not my first choice of CPU and graphics card, did an admirable job of playing the games I'm likely to be seen playing these days. It ran Tomb Raider on ultra at 68 frames-per-second, BioShock Infinite at 82 and Shogun 2: Total War at a respectable 64 on highest settings. It's not a machine meant to break land-speed graphics records, but it's a damn fine starting point with plenty of room to expand. It's exactly the sort of system I would build if I still had the time or inclination to make my PC gaming a little more personal.

I could also show you this really cool picture of the cooling pipes bathed in red LED light.

S

Digital Storm's aim with the Vanquish line is to end the age-old DIY Vs. pre-built debate. It will not do that, not because it doesn't deliver what it promises, but because folks that build themselves PCs can always go to eBay or one of the hundreds of discount online stores with websites from the late 90s and find bargains. The Vanquish will not likely silence them.

What the Vanquish can do make those that would rather not build their own PC an excellent system backed by warranty and support that feels like a system they could have put together themselves, because they certainly could of.

The Vanquish line is available for purchase now at Digital Storm.

This week Nvidia released its latest high-tech graphics card, the GeForce GTX Titan. The? Read?

Reinforcing Safety with an Electronic Message Board Program

Reinforcing Safety with an Electronic Message Board Program

By Jude Carter

Sanitation workers consistently make it onto the list of the top 10 most dangerous occupations as tracked by The Bureau of Labor Statistics. It?s no wonder since they are often working in the dark, carrying heavy loads, working in traffic, handling hazardous materials, maneuvering large trucks in tight spaces and battling fatigue. Communication is a key factor in reinforcing safe behavior, yet reaching workers can be challenging when they spend most of their time on the road.

Increasingly, solid waste companies are installing electronic message boards at their facilities as a way to improve communication. The need for a mobile communications option is also becoming critical with the rapid growth of smart phone and tablet use. Most companies underestimate what?s involved in developing an effective program. There are three components to a successful deployment?

Israeli official: Syria's Assad used chemical arms

TEL AVIV, Israel (AP) ? A senior Israeli military intelligence official said on Tuesday that Syrian President Bashar Assad used chemical weapons last month in his battle against insurgent groups. It was the first time that Israel has accused the embattled Syrian leader of using his stockpile of nonconventional weapons.

The assessment could raise pressure on the U.S. and other Western countries to intervene in the Syrian conflict. Britain and France recently announced that they had evidence that Assad's government had used chemical weapons. Although the U.S. says it has not been able to verify these claims, President Barack Obama has warned that the introduction of chemical weapons by Assad would be a "game changer."

Israel, which borders southwestern Syria, has been warily watching the Syrian civil war since the fighting erupted there in March 2011. Although Assad is a bitter enemy, Israel has been careful not to take sides, partly because the Assad family has kept the border with Israel quiet for the past 40 years and partly because of fears of what would happen if he is toppled.

Israeli officials are especially concerned that Assad's stockpile of chemical weapons and other advanced arms could reach the hands of Assad's ally, the Hezbollah militant group in Lebanon, or Islamic extremist groups trying to oust him. The concern is that if Assad is overthrown, any of these groups could turn his sophisticated arsenal against Israel. Hezbollah battled Israel to a monthlong stalemate in 2006.

In his assessment, Brig. Gen. Itai Brun, the head of research and analysis in Israeli military intelligence, told a security conference in Tel Aviv that Assad has used chemical weapons multiple times. Among the incidents were attacks documented by the French and British near Damascus last month.

"To the best of our professional understanding, the regime used lethal chemical weapons against the militants in a series of incidents over the past months, including the relatively famous incident of March 19," Brun said. "Shrunken pupils, foaming at the mouth and other signs indicate, in our view, that lethal chemical weapons were used."

He said sarin, a lethal nerve agent, was probably used. He also said the Syrian regime was using less lethal chemical weapons, and that Russia has continued to arm the Syrian military with weapons such as advanced SA-17 air defense missiles.

Brun appeared to lament the lack of response by the international community, saying the silence could encourage rogue groups that do not play by traditional rules of war.

"The fact that chemical weapons were used without an appropriate response is a very disturbing development because it could signal that such a thing is legitimate," he said. "I think we need to be very worried that chemical weapons will reach elements that are less responsible."

Brun did not elaborate or provide any of the additional evidence he had gathered.

He delivered his assessment as U.S. Defense Secretary Chuck Hagel was wrapping up a visit to Israel.

Reacting to Brun's comments, Pentagon spokesman George Little said the U.S. "continues to assess reports of chemical weapons use in Syria."

"The use of such weapons would be entirely unacceptable," he added." ''We reiterate in the strongest possible terms the obligations of the Syrian regime to safeguard its chemical weapons stockpiles, and not to use or transfer such weapons to terrorist groups like Hezbollah."

Israeli Prime Minister Benjamin Netanyahu on Monday repeated that Israel has the right "to defend itself" against any threat. He spoke at a meeting Hagel.

At a meeting with Hagel on Monday, Israel's defense minister, Moshe Yaalon, laid out a number of "clear red lines" to Syria that could trigger an Israeli response. Among them were transferring sophisticated weapons to Hezbollah and other "rogue elements" in Syria, cross-border attacks into Israel or "rogue elements" getting hold of Syrian chemical weapons.

The Israeli military has fired at targets inside Syria on several occasions in response to gunfire or mortar shells landing in the Israeli-occupied Golan Heights. Israel has all but admitted that it carried out an airstrike in Syria in January that destroyed a shipment of anti-aircraft missiles believed to be headed to Hezbollah.

"We proved it. When they crossed these red lines, we operated, we acted," Yaalon said.

While Israel has focused on the dangers of militants obtaining chemical weapons, the West has expressed a broader concern about any use of chemical weapons in Syria.

Britain and France informed U.N. Secretary-General Ban Ki-moon last month that they have reliable evidence Assad's forces used chemical weapons that caused injuries and deaths. They cited soil samples and interviews with witnesses and opposition figures.

The two countries asked the U.N. chief to investigate allegations of chemical weapons use in two locations near Damascus on March 19, as well as in the city of Homs on Dec. 23. Ban has appointed a team of chemical weapons experts to investigate the allegations, but the Syrian government has largely blocked the team from doing its work. Syria, meanwhile, has accused rebels of using chemical weapons.

The chairman of the Joint Chiefs of Staff, Gen. Martin Dempsey, acknowledged last week that he could not guarantee that U.S. forces could secure the chemical weapons caches within Syria. He said Syria has been moving the weapons between numerous sites.

Syria is believed to have hundreds, perhaps thousands, of tons of chemical agents, including mustard gas, a blistering agent, and the more lethal nerve agents, sarin and VX.

During a trip to Israel last month, Obama warned that the use of chemical weapons would be a "game changer." He said if confirmed, "the international community has to act on that additional information," but did not detail what the next steps would be.

Amos Yadlin, a retired chief of Israeli military intelligence who heads the Institute for National Security Studies that hosted Tuesday's conference, urged the U.S. to intervene. He said the red line in Syria had been crossed and that the U.S. should act.

Not doing so would "strengthen the opinion of those, particularly in Israel, who are suspicious of America's commitment when red lines are crossed," he said. He suggested the U.S. impose a no-fly zone over Syria or even initiate a bombing campaign similar to the one conducted against the regime of late Libyan dictator Moammar Gadhafi.

"So far they haven't applied any leverage to Bashar, and this has allowed him to do what Gadhafi could never do," Yadlin told The Associated Press.

Study shows reproductive effects of pesticide exposure span generations

Tuesday, April 23, 2013

North Carolina State University researchers studying aquatic organisms called Daphnia have found that exposure to a chemical pesticide has impacts that span multiple generations ? causing the so-called "water fleas" to produce more male offspring, and causing reproductive problems in female offspring.

"This work supports the hypothesis that exposure to some environmental chemicals during sensitive periods of development can cause significant health problems for those organisms later in life ? and affect their offspring and, possibly, their offspring's offspring," says Dr. Gerald LeBlanc, a professor of environmental and molecular toxicology at NC State and lead author of a paper on the work. "We were looking at a model organism, identified an important pathway for environmental sex determination, and found that there are chemicals that can hijack that pathway."

Environmental cues normally determine the sex, male or female, of Daphnia offspring, and researchers have been working to understand the mechanisms involved. As part of that work, LeBlanc's team had previously identified a hormone called methyl farnesoate (Mf) that Daphnia produce under certain environmental conditions.

The researchers have now found that the hormone binds with a protein receptor called the Mf receptor, which can regulate gene transcription and appears to be tied to the production of male offspring.

In experiments, the researchers exposed Daphnia to varying levels of an insecticide called pyriproxyfen, which mimics the Mf hormone. The pyriproxyfen exposure resulted in Daphnia producing more male offspring and fewer offspring in total, with higher doses exacerbating both effects.

"At high concentrations, we were getting only male offspring, which is not good," LeBlanc says. "Producing fewer offspring, specifically fewer female offspring, could significantly limit population numbers for Daphnia."

And low exposure concentrations had significant impacts as well. At pyriproxyfen concentrations as low as 71 nanograms per liter, or 71 parts per trillion, the Daphnia would still produce some female offspring. But those females suffered long-term reproductive health effects, producing significantly smaller numbers of offspring ? despite the fact that they had not been exposed to pyriproxyfen since birth.

"We now want to know specifically which genes are involved in this sex determination process," LeBlanc says. "And, ecologically, it would be important to know the impact of changes in population dynamics for this species. Daphnia are a keystone species ? an important food source for juvenile fish and other organisms."

The paper, "A Transgenerational Endocrine Signaling Pathway in Crustacea," was published April 17 in PLOS ONE. The paper was co-authored by Dr. Ying Wang, a research associate at NC State; Charisse Holmes and Elizabeth Medlock, Ph.D. students at NC State; and Gwijun Kwon, a research technician at NC State.
