Symantec shares plunge, traders see mini 'flash crash'

By Ryan Vlastelica

(Reuters) - Shares of Symantec Corp plunged some 10 percent in a matter of seconds on Tuesday before being halted by the Nasdaq, in the latest instance of what traders called a single-stock "flash crash."

There was no news on the security software maker that triggered the move around 10:11 a.m. EDT.

The plunge recalled the "flash crash" of May 2010 because Symantec said Tuesday's fall was also caused by a large sell order.

Symantec spokesman Cris Paden said somebody put in the large order without specifying a bottom limit at which they were willing to sell the stock. That prompted buyers to sharply mark down their bids as they snapped up the shares.

Once the decline reached 10 percent, an automatic halt in trading was triggered on the Nasdaq Stock Market. Wayne Lee, a spokesman for Nasdaq OMX Group, which operates the Nasdaq, said no trades are being canceled.

"It was not necessarily an erroneous trade, so it likely won't be corrected," Paden said, adding that it was the first time such a situation had occurred with Symantec's stock, though he didn't not know how frequently it had happened to shares of other companies.

Shares of Symantec resumed trading five minutes after being halted, and bounced back above $24. They were down 1.3 percent to $24.26 in midday trading.

Approximately 504,000 Symantec shares were traded in a three-second period that saw the stock dive from $24.40 to a low of $21.93 before it was halted. Trades were executed on numerous exchanges, but the heaviest volume was seen on the Nasdaq Stock Exchange, according to Thomson Reuters data.

Regulators concluded the "flash crash" almost three years ago was caused by a large seller that created an imbalance in the market. The May 6, 2010 flash crash saw the Dow fall more than 600 points in a matter of minutes.

The dominance of electronic trading has been a point of contention for many traders who believe it exaggerates violent moves in equities.

Before the prevalence of high-frequency trading, "a series of market makers would have filled this mistake with substantially less carnage," said Sal Arnuk, co-manager of trading at Themis Trading in Chatham, New Jersey.

"Today's market structure is perfectly set up to take advantage of any and all missteps in the most efficient manner ... if you were day-trading this, or had a stop-loss order in, then you got hit not because of your thesis, but because of a market structure issue."

Paden said this was the first time he could recall such an issue with Symantec shares. It is rare that companies comment on unusual moves in their stock price.

These moves rattle investors with their violent natures and lack of warning. When this happens, some market makers that provide liquidity will withdraw their bids, while investors are hit with stop-loss orders, which are directions to automatically sell a stock if it breaches a particular threshold.

"Liquidity is an illusion... it's never truly there when it's needed. It vaporizes in an instant, then quickly reappears to trap the suckers who just sold into the void," said Sean McLaughlin, director of investor relations solutions at StockTwits in Boulder, Colorado.

McLaughlin added that he only traded options now "so as to be insulated from these egregious breaches of market structure."

Grocery delivery service is greener than driving to the store

Monday, April 29, 2013

At the end of a long day, it can be more convenient to order your groceries online while sitting on the living room couch instead of making a late-night run to the store. New research shows it's also much more environmentally friendly to leave the car parked and opt for groceries delivered to your doorstep.

University of Washington engineers have found that using a grocery delivery service can cut carbon dioxide emissions by at least half when compared with individual household trips to the store. Trucks filled to capacity that deliver to customers clustered in neighborhoods produced the most savings in carbon dioxide emissions.

"A lot of times people think they have to inconvenience themselves to be greener, and that actually isn't the case here," said Anne Goodchild, UW associate professor of civil and environmental engineering. "From an environmental perspective, grocery delivery services overwhelmingly can provide emissions reductions."

Consumers have increasingly more grocery delivery services to choose from. AmazonFresh operates in the Seattle area, while Safeway's service is offered in many U.S. cities. FreshDirect delivers to residences and offices in the New York City area. Last month, Google unveiled a shopping delivery service experiment in the San Francisco Bay Area, and UW alumni recently launched the grocery service Geniusdelivery in Seattle.

As companies continue to weigh the costs and benefits of offering a delivery service, Goodchild and Erica Wygonik, a UW doctoral candidate in civil and environmental engineering, looked at whether using a grocery delivery service was better for the environment, with Seattle as a test case. In their analysis, they found delivery service trucks produced 20 to 75 percent less carbon dioxide than the corresponding personal vehicles driven to and from a grocery store.

They also discovered significant savings for companies ? 80 to 90 percent less carbon dioxide emitted ? if they delivered based on routes that clustered customers together, instead of catering to individual household requests for specific delivery times.

"What's good for the bottom line of the delivery service provider is generally going to be good for the environment, because fuel is such a big contributor to operating costs and greenhouse gas emissions," Wygonik said. "Saving fuel saves money, which also saves on emissions."

The research was funded by the Oregon Department of Transportation and published in the Journal of the Transportation Research Forum.

The UW researchers compiled Seattle and King County data, assuming that every household was a possible delivery-service customer. Then, they randomly drew a portion of those households from that data to identify customers and assign them to their closest grocery store. This allowed them to reach across the entire city, without bias toward factors such as demographics and income level.

They used an Environmental Protection Agency modeling tool to calculate emissions at a much more detailed level than previous studies have done. Using factors such as vehicle type, speed and roadway type, they calculated the carbon dioxide produced for every mile for every vehicle.

Emissions reductions were seen across both the densest parts and more suburban areas of Seattle. This suggests that grocery delivery in rural areas could lower carbon dioxide production quite dramatically.

"We tend to think of grocery delivery services as benefiting urban areas, but they have really significant potential to offset the environmental impacts of personal shopping in rural areas as well," Wygonik said.

Work commuters are offered a number of incentives to reduce traffic on the roads through discounted transit fares, vanpools and carpooling options. Given the emissions reductions possible through grocery delivery services, the research raises the question of whether government or industry leaders should consider incentives for consumers to order their groceries online and save on trips to the store, Goodchild said.

In the future, Goodchild and Wygonik plan to look at the influence of customers combining their grocery shopping with a work commute trip and the impact of the delivery service's home-base location on emissions.

Lenovo IdeaPad Yoga 11 review

Lenovo IdeaPad Yoga 11 review

Normally, when a company releases two laptops in different sizes (the MacBook Air, anyone?) we review just one: we assume you'll get the gist about the design and trackpad the first time, ya know? So it's funny, then, that we're taking a look at the Lenovo IdeaPad Yoga 11 after we've already tested the Yoga 13 and named it one of our favorite Windows 8 convertibles. They look alike, with an inventive hinge allowing you to fold the screen back like a book cover. The keyboards are the same too, though the 11-incher's is understandably a tad more crowded. They even have the same oddly shaped power port.

Except, of course, they're totally different products. Whereas the Yoga 13 is a proper laptop, with a Core i5 processor and full Windows 8, the Yoga 11 runs Windows RT, and is powered by a Tegra 3 chip (yes, the same one you're used to seeing in Android tablets). That means a big dip in performance, but exponentially longer battery life. Legacy x86 apps are off-limits too, given that this is Windows RT and all. Now that we've set up that equation for you (weaker performance plus longer battery life minus standard Windows apps equals what?) let's meet up after the break to see if this is just as good a deal as its big brother.

Fashion-Focused Startups Stylit And Black Tag Offer Free, Personal Shoppers For Both Women & Men

outfitE-commerce is booming, but shopping for clothing online can still be a challenge. Unlike many consumer products, clothing is personal and often needs to be tried on for fit. Plus, there are numerous options available via the web, so sometimes it’s tough to even know where to begin with an online shopping expedition. Two companies from TechCrunch Disrupt NY’s Startup Alley are addressing these problems by offering personal stylists and recommendations online. One, Stylit, is targeting women and another,?Black Tag, is focused on men. Stylists-as-a-service? Yep, it’s that kind of thing. Tel Aviv-based Stylit’s co-founder and chief stylist Maya Kramer has a decade’s worth of experience in the fashion industry: She’s worked as a stylist herself, as well as a personal shopper, photo shoot producer, boutique owner, fashion writer, styling instructor, model and even TV personality. Her clients have included Vogue, Sak?s Fifth Avenue, Microsoft, Glamour, Target, Victoria?s Secret and various celebrities, designers and artists. Others on the founding team include CEO Yaniv Nissim, CTO Michael Gutkin, and lead engineer Shilo Ayalon. “We feel that personal styling was not accessible to everyone,” explains Kramer. “Stylit solves this.” After signing up on the website, users are prompted to fill out a questionnaire, detailing their budget, body type, and personal tastes. Stylit’s personal shoppers will then curate a selection of outfits based on these answers. The outfits, sent out on a weekly basis, don’t just include the clothing, but also accessories like shoes, bags, hats, jewelry, etc. Users can choose to buy the outfit and/or the individual items, or just pass altogether. But to help the stylists better learn their own personal tastes, users are also asked to rank the outfits they’re sent, allowing the recommendations to improve over time. Unlike with many stylists in the offline world – and even some found online – there’s no charge to use Stylit’s personal shopping service. Instead, the company is monetized through affiliate sales for now, though Kramer explains that longer-term, the company could work with brands directly to help them connect with those who best fit their target demographic. In addition, the company wants to eventually build each of their users their own personalized stores that provide items that fit their body type and style preference, says Kramer, who calls this bigger vision a “Pandora for online shopping.” The stylists work for the site on a freelance basis. This differentiates the service from

Millions in CIA "ghost money" paid to Afghanistan president's office: NYT

(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, the New York Times says, 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."

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.

In response to the report, Karzai told reporters in Helsinki after a meeting with Finnish leaders that the office of the National Security Council had been receiving support from the U.S. government for the past 10 years. He said the amounts had been "not big" and the funds were used for various purposes including assistance for the wounded.

"It's multi-purpose assistance," he said, without commenting on the report's claims the funds fuelled corruption and empowered warlords.

However, Afghan Foreign Ministry spokesman Janan Mosazai told reporters in Kabul that there was no proof or evidence to back up the claims in the story.

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

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.

Nahid Fareed, a member of parliament from western Herat province, who usually supports Karzai's government, said the claims in the story represented a "serious issue".

"Any hidden money that the palace receives from indirect channels, such as spy agencies, notably the CIA, is against national interest and is treason," Fareed told Reuters.

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.

Utah excels in economy and business: Chamber of Commerce report

WASHINGTON (Reuters) - When it comes to economic growth and business strength, there may be no better U.S. state than Utah, according to a report set to be released by the U.S. Chamber of Commerce on Monday.

The business association found that Utah, population 2.8 million, ranked third among all states in overall economic performance - a measure of how states' economies have fared over time in terms of jobs, gross domestic product, productivity and income.

Moreover, Utah was the only state to make the top 10 lists for all five of the "policy" areas the Chamber assessed - exports, innovation and entrepreneurship, business climate, talent pipeline and infrastructure.

"Utah is the strongest job growth performer behind North Dakota ... The state is becoming known as a professional services and finance center," said the Chamber. "Manufacturing is a competitive advantage for the state. Over the past decade, Utah's manufacturing sector saw a slight increase in employment during a time when national manufacturing employment contracted by 22.51 percent."

Utah's unemployment rate is one of the lowest among the states at 4.9 percent in March 2013, according to the U.S. Labor Department.

Each year the Chamber ranks states according to various economic and business measures for its "Enterprising States" report. This year, fortune seemed directly tied to technology and engineering across the five areas the Chamber evaluates.

For exports, Utah came in third after Louisiana and Texas, primarily because it is a major supplier to the world of electronic memory circuits, aircraft engines and parts, vehicle airbags and X-ray equipment, according to the Chamber.

Utah had top rankings in entrepreneurship mostly because it is establishing high-tech businesses at a fast rate.

The Chamber also considered Utah strong in the "talent pipeline" area, which looks at both education and training as well as job assistance programs after the state legislature approved funds to foster more engineering graduates and software developers.

Technology was even a factor for Utah's top ranking in infrastructure, with the Chamber emphasizing Utah's high-speed data connections alongside the high quality of the state's bridges.

For the business climate measure, which assesses the influence of government-related costs on local businesses, the Chamber put Utah sixth because of its high small-business lending activity, low taxes and laws.

Technology also gave Maryland and Virginia a boost in the Chamber's report.

The Chamber ranked Maryland first in entrepreneurship, largely because of its research and development and its science and technology employment growth, and Virginia third partly for having the highest share of businesses in high-tech industries.

Still, the extraction and the commodities boom continues to prove crucial for jobs, business and incomes in most states.

North Dakota's "stratospheric growth" from the oil and natural gas industry put it first on the list of economic performance, followed by Texas, which has added 41,000 jobs in natural resources extraction in the last two years, according to the Chamber.

Three other energy heavyweights completed the top 10 economic performance list, with Wyoming fourth, Oklahoma seventh and Louisiana eighth.

The Chamber of Commerce is not the only one to notice that certain states are bounding ahead as the recovery from the 2007-09 recession unfolds. Earlier this month, Standard & Poor's Ratings Service said it expected to find the strongest growth this year in the Rocky Mountain region, including Utah and Wyoming, and in the West South Central area encompassing Louisiana, Oklahoma and Texas.

Sanford, Colbert Busch debate for first time

CHARLESTON, S.C. (AP) ? Former South Carolina Gov. Mark Sanford and Democrat Elizabeth Colbert, after sparring from a distance for weeks, finally face off Monday in the pitched race for the state's vacant 1st Congressional District seat.

The two meet Monday evening at The Citadel in a debate sponsored by the Patch news service, the South Carolina Radio Network and Charleston television station WCBD. The debate is being cablecast by C-SPAN.

It's their first joint appearance in the campaign that started earlier when incumbent congressman Tim Scott was appointed to the state's vacant U.S. Senate seat. Sanford and Colbert Busch, as well as Green Party Candidate Eugene Platt, compete May 7 in a special election in the district that runs from northeast of Charleston south to the resort of Hilton Head Island.

Sanford's public career was sidelined in 2009 after he revealed he had an extramarital affair with an Argentine woman to whom he is now engaged. For weeks now, Sanford has been trying to make a political comeback, hammering Colbert Busch, the sister of comedian Stephen Colbert, for not debating more.

Sanford has accused her of running what he called a stealth campaign, fueled by out-of-state money and that the voters don't know where she stands on the issues.

"In the absence of everything else this (debate) takes on added significance because she hasn't debated," Sanford said.

Colbert Busch's campaign has responded that she has been busy with her own aggressive campaign schedule.

"I'm really looking forward to this debate," Colbert Busch said Friday. "I think what you will see when Mark and I are standing on the same stage is you will see an enormous difference between the two of us and you will see an enormous difference between the two campaigns. I'm really looking forward to it."

But she said she didn't think the campaign turns on the debate.

"I think people understand our campaign and what our campaign is doing resonates throughout the district," she added.

Mystery clouds deadly clash in western China with 'suspected terrorists'

Some say that Beijing deliberately exaggerates the terrorist threat in order to justify the iron grip it keeps on the Muslim majority province of Xinjiang in?western China.

By Peter Ford,?Staff Writer / April 24, 2013

A woman looks up as a dust storm hits Kashgar, Xinjiang Uighur Autonomous Region, last week. Xinjiang, once a predominantly Muslim province in China's far west, has seen massive settlement by ethnic Han immigrants in recent decades.

Mystery surrounds official Chinese reports Wednesday of a violent clash between ?suspected terrorists? and the authorities in the restive Muslim province of Xinjiang yesterday that left 21 people dead, including 15 officials.

According to a statement on the provincial government website, a group ?planning to conduct violent terrorist activities? armed with knives seized three local officials who had surprised them in a house near the city of Kashgar (see map).

They then killed the three hostages and 12 of the policemen and local community workers who came to the rescue, setting fire to the house before armed police regained control of the situation, killing six of the suspects and arresting eight of them, the statement said.

The Chinese authorities have given only sketchy details of the incident, and have not accused any particular group of responsibility. Beijing has previously blamed Islamist separatists for earlier violent attacks on officials.

Xinjiang, once a predominantly Muslim province in China?s far west, has seen massive settlement by ethnic Han immigrants in recent decades. Local people complain that their culture and language are being eroded and that Han now outnumber original inhabitants, who are ethnic Uighurs, with linguistic and cultural ties to central Asian peoples.

Violence flares sporadically, despite a stiflingly heavy handed police and army presence. In 2009 almost 200 people were killed ? mostly ethnic Han ? in deadly rioting in the provincial capital of Urumqi. Last month the government announced that courts in Xinjiang had sentenced 20 men to prison terms as long as life for plotting jihadi attacks.

The men ?had their thoughts poisoned by religious extremism,? according to the Xinjiang provincial website, and had ?spread Muslim religious propaganda.?

Determining the truth behind such allegations, and incidents such as Tuesday?s clash,?is difficult. Chinese media are not allowed to carry reports other than those by the state-run news agency Xinhua and foreign reporters have found themselves restricted and harassed when trying to work in Xinjiang.

A leading Uighur activist, Dilxat Raxit, who lives in Germany, questioned the official account, telling the AP that local residents had reported that the police sparked the incident by shooting a Uighur youth during a house search.

It was not clear how the suspects, armed only with knives, had managed to kill 15 policemen and local officials before they were subdued.

China has often accused a shadowy group known as the East Turkestan Islamic Movement of being behind violence in Xinjiang, but foreign observers are dubious, with some saying that Beijing deliberately exaggerates the terrorist threat in order to justify the iron grip it keeps on Xinjiang.

The US State Department put the group on its terrorist watch list in 2002, but has since removed it amid doubts about whether the group is a real organization.?

Will Chael Sonnen hang it up for good after UFC 159 loss to Jon Jones?

Minutes after losing by TKO to UFC light heavyweight Jon Jones, Chael Sonnen indicated his fighting days may be over.

"I'm not going to be one of the guys to hang around. If there's not a road to the title, then this sport isn't for me. I believe that was probably my last opportunity," Sonnen said to UFC commentator Joe Rogan.

He didn't specifically say "I'm retiring," but he did talk about the end of the road. This seems like more than the emotional ramblings of a fighter after a bad loss. B.J. Penn threatened retirement several times before it stuck. Nick Diaz has retired and unretired plenty of times.

Retirement wouldn't be out of the question. He's 36 years old and has fought in 40 fights after a long career as an amateur and collegiate wrestler.

If he does decide to retire, don't expect him to play shuffleboard and take up gardening. He already works as a commentator for Fox's broadcasts. During the last season of "The Ultimate Fighter," he proved to be a capable coach. Retirement would not mean Sonnen was done with MMA.

Sonnen talked his way into a title shot with Jones just months after he dropped a title shot to Anderson Silva at middleweight. Deserved or not, Sonnen has had several chances to win the UFC belt, and he hasn't won any of them. Not many fighters get more chances than he has. If the belt is the only thing that's important, why not retire?

Why the alleged Boston bombers' mom probably won't be extradited

Zubeidat Tsarnaeva may stay out of American custody because the US and Russia do not have a bilateral extradition treaty, despite efforts by Moscow to negotiate one.

The mother of the two Boston bombing suspects, Zubeidat Tsarnaeva, has become a focus of interest after it emerged that her name had been added to a key terrorist watchlist in 2011 and fresh materials, including wiretaps, handed over to the US by the Russians showed her "vaguely discussing" jihad with her elder son two years ago.?

Ms. Tsarnaeva, a naturalized US citizen who moved back to Russia a few years ago, has best been known until now as the most passionate defender of her two sons, Tamerlan and Dzhokhar, up to the point of insisting that they were "framed" because they were Muslims. Now investigators may want to look into what role she may have played, if any, in the radicalization process that may have led her two sons to carry out the Boston Marathon bombing almost two weeks ago.

Tsarnaeva was reportedly added to the Terrorist Identities Datamart Environment (TIDE)?database in 2011 at the request of US intelligence agencies. That list, which held about 750,000 names at the time, is used to compile the consolidated Terrorist Watchlist?used as the main reference tool by airlines and law enforcement agencies. It is believed her name, and that of her son Tamerlan, were appended to the list after the Russian FSB security service appealed for more information about the pair to the FBI and the CIA and warned of their growing radicalization.?

In recent days the Russians have also turned over wiretaps of conversations between Tsarnaeva, who was by that time back living in her native Dagestan, and her son Tamerlan in Boston. In one they reportedly discuss "jihad" in a general way. In another, Tsarnaeva is recorded talking with someone who is under FBI investigation in an unrelated case.

In his annual town hall meeting with the Russian public last Thursday, President Vladimir Putin called for stepped up security cooperation?between the US and Russia in the wake of the Boston tragedy. He downplayed any links between Russia and the Boston bombers, and added "to our great regret" Russian security forces lacked any "operative information" that they might have shared with US law enforcement in the run up to the attack.

Researchers identify key cellular organelle involved in gene silencing

Friday, April 26, 2013

RNA molecules, made from DNA, are best known for their role in protein production. MicroRNAs (miRNAs), however, are short (~22) nucleotide RNA sequences found in plants and animals that do not encode proteins but act in gene regulation and, in the process, impact almost all biological processes ? from development to physiology to stress response.

Present in almost in every cell, microRNAs are known to target tens to hundreds of genes each and to be able to repress, or "silence," their expression. What is less well understood is how exactly miRNAs repress target gene expression.

Now a team of scientists led by geneticists at the University of California, Riverside has conducted a study on plants (Arabidopsis) that shows that the site of action of the repression of target gene expression occurs on the endoplasmic reticulum (ER), a cellular organelle that is an interconnected network of membranes ? essentially, flattened sacs and branching tubules ? that extends like a flat balloon throughout the cytoplasm in plant and animal cells.

"Our study is the first to demonstrate that the ER is where miRNA-mediated translation repression occurs," said lead researcher Xuemei Chen, a professor of plant cell and molecular biology and a Howard Hughes Medical Institute-Gordon and Betty Moore Foundation Investigator. "To understand how microRNAs repress target gene expression, we first need to know where microRNAs act in the cell. Until now no one knew that membranes are essential for microRNA activity. Our work shows that an integral membrane protein, AMP1, is required for the miRNA-mediated target gene repression to be successful. As AMP1 has counterparts in animals, our findings in plants could have broader implications."

Study results appear today in the journal Cell.

Simply put, DNA makes RNA, and then RNA makes proteins. Specifically, RNA encodes genetic information that can be "translated" into the amino acid sequence of proteins. But noncoding RNAs ? RNAs that do not encode proteins ? are increasingly found to act in numerous biological processes. MicroRNAs are a class of noncoding RNAs whose main function is to downregulate gene expression.

Research on miRNAs has increased tremendously since they were first identified about 20 years ago. In the case of diseases, if some genes are up- or down-regulated, miRNAs can be used to change the expression of these genes to fight the diseases, thus showing therapeutic potential.

MicroRNAs are known to regulate target genes by two major modes of action: they either destabilize the target RNAs, leading to their degradation, or they do not impact the stability of the target RNAs, but simply prevent them from being translated into proteins ? a process known as translation inhibition. The end result of translation inhibition is that the genes do not get expressed. Just how miRNAs cause translational inhibition of their target genes is not well understood.

"We were surprised that the ER is required for the translational inhibition activity of miRNAs," Chen said. "This new knowledge will expedite our understanding of the mechanism of gene silencing. Basically, now we know where to look: the ER. We also suspect it is the rough ER portions that are involved."

Chen explained that the ER has two types: rough and smooth. Rough ER, which synthesizes and packages proteins, looks bumpy; smooth ER, which acts in lipid synthesis and protein secretion, resembles tubes. The ER protein AMP1, she said, is anchored in the rough ER.

"My lab has been conducting research on AMP1 for many years," she said. "And it's this protein that drew our attention to the ER. First, we realized that AMP1 is involved in miRNA-mediated translational inhibition. Then, since we already knew that AMP1 is localized in the rough ER, we shifted our focus to this organelle."

Next, her lab will attempt to crack the mechanism of miRNA-mediated translational inhibition. They will investigate, too, how miRNAs are recruited to the ER.

MADRID, April 25 (Reuters) - Playmaker Andres Iniesta has dismissed the idea Barcelona are at the end of an era following their 4-0 Champions League mauling by Bayern Munich. Barca, who lifted the trophy in 2009 and 2011, were the favourites to win the competition ahead of Tuesday's semi-final first leg but they were so outclassed by the Germans that many pundits believe their recent spell of dominance is over. "I think it is unfair to talk of a cyclical change," the Spanish World Cup winner told a news conference on Thursday. ...

Roundworm quells obesity and related metabolic disorders

Apr. 25, 2013 ? Researchers at the University of Maryland School of Medicine, Baltimore, have shown in a mouse model that infection with nematodes (also known as roundworms) can not only combat obesity but ameliorate related metabolic disorders. Their research is published ahead of print online in the journal Infection and Immunity.

Gastrointestinal nematodes infect approximately 2 billion people worldwide, and some researchers believe up until the 20th century almost everyone had worms. In developed countries there is a decreasing incidence of nematode infection but a rising prevalence of certain types of autoimmunity, suggesting a relationship between the two. Nematode infection has been purported to have therapeutic effects and currently clinical trials are underway to examine worms as a treatment for diseases associated with the relevant cytokines, including inflammatory bowel disease, multiple sclerosis, and allergies.

In the study researchers tested the effect of nematode infection on mice fed a high-fat diet. Infected mice of normal girth gained 15 percent less weight than those that were not infected. Mice that were already obese when infected lost roughly 13 percent of their body weight within 10 days. Infection also drastically lowered fasting blood glucose, a risk factor for diabetes, and reduced fatty liver disease, decreasing liver fat by ~25 percent, and the weight of the liver by 30 percent.

The levels of insulin and leptin also dropped, "indicating that the mice restored their sensitivities to both hormones," says corresponding author Aiping Zhao of the University of Maryland School of Medicine, Baltimore. Leptin moderates appetite. As with too much insulin, too high a level of leptin results in insensitivity, thus contributing to obesity and metabolic syndrome, Zhao explains.

The mechanism of the moderation of these hormones "was associated with a parasite-induced reduction in glucose absorption in the intestine, reduced liver triglycerides, and an increase in the population of cells called "alternatively activated macrophages," which regulate glucose metabolism and inflammation," says coauthor Joe Urban of the United States Department of Agriculture. Some of these changes involved "a protein called interleukin-13 and related intracellular signaling mechanisms," he says. "This suggests that there are immune related shifts in metabolism that can alter expression of obesity and related metabolic syndrome."

The incidence of obesity has been climbing dramatically, worldwide. It is a key risk factor for many metabolic diseases, including diabetes, hypertension, and heart disease. Recent studies indicate that it is accompanied by chronic low-grade inflammation in adipose tissues, causing the release of proinflammatory cytokines and chemokines that contribute to the development of cardiovascular disease and metabolic syndrome.

Parasitic nematode infection induces a marked elevation in host immune Th2-cells and related type 2 cytokines which, besides combating the infection, also have potent anti-inflammatory activity, according to the report.

Tiny satellites + cellphones = cheaper 'eyes in the sky' for NASA

NASA is exploring ways to send a flotilla of small satellites to a destination, rather than one large orbiter. In a first test, three tiny satellites are now on orbit and beeping back at Earth. Why the idea could be an aid to scientific research.

By Pete Spotts,?Staff writer / April 24, 2013

NASA's Phonesat aims to demonstrate the ability to launch one of the lowest-cost, easiest-to-build satellites ever flown in space ? capabilities enabled by using off-the-shelf consumer smart phones.

Three satellites, to be exact, released into orbit on Sunday with the launch of Orbital Sciences Corp.'s new Antares rocket, the latest addition to NASA's stable of space-station resupply vehicles.

The tiny satellites, each occupying a cube four inches on a side, represent an experiment in using cheap but powerful off-the-shelf technology to run a new generation of small, affordable science satellites.

Two of these orbiters, which NASA has dubbed Phonesat 1.0, use the electronics and sensors packaged in a Google Nexus One smart phone to serve as on-board computers. Accelerometers that normally tell the phones which way you've oriented the screen now gather information on the satellites' orientation in space. And the cameras? Yep, snapshots of Earth from 156 miles up.

The third satellite, a prototype for Phonesat 2.0, uses a more powerful Nexus S, which also has a built-in gyroscope. Ultimately, engineers plan to use that extra capability to control solar panels and to control the spacecraft's orientation, instead of just recording it.

The notion of using a smart phone's innards to run a satellite grew out of informal hallway chatter, recalls James Cockrell, project manager for Phonesat at NASA's Ames Research Center at Moffett Field, Calif.

The benchmark people often use as a point of comparison for the power of their favorite laptop or smart phone is the primitive computing power used in the Apollo program, which landed humans on the moon and brought them back safely in the late 1960s and early '70s.

Indeed, Mr. Cockrell describes a trip to the Internet that netted him the electronic-circuit diagram for the navigation and control computer used in Apollo's Lunar Excursion Module.

"Oh my goodness, you could build it in your basement" with a circuit board and a few transistors, he says.

A couple of years ago, he says, an engineer at NASA-Ames was drawing a similar comparison between his smart phone and today's satellites during an informal hallway chat. The engineer noted that a smart phone's processor is 10 to 15 times more powerful than the processors used in a conventional satellite's computer. A smart phone has much more memory. And it boasts a GPS receiver, gyroscopes, and accelerometers ? the sensors needed for navigation and to control a satellite's orientation.

"He said: 'I don't know why we couldn't make a satellite our of a smart phone,' " Cockrell recalls. Although it took a bit of additional salesmanship to convince folks higher up the organizational food chain, the Phonesat project was born.

Infants' sweat response predicts aggressive behavior as toddlers

Apr. 23, 2013 ? Infants who sweat less in response to scary situations at age 1 show more physical and verbal aggression at age 3, according to new research published in Psychological Science, a journal of the Association for Psychological Science.

Lower levels of sweat, as measured by skin conductance activity (SCA), have been linked with conduct disorder and aggressive behavior in children and adolescents. Researchers hypothesize that aggressive children may not experience as strong of an emotional response to fearful situations as their less aggressive peers do; because they have a weaker fear response, they are more likely to engage in antisocial behavior.

Psychological scientist Stephanie van Goozen of Cardiff University and colleagues wanted to know whether the link between low SCA and aggressive behaviors could be observed even as early as infancy.

To investigate this, the researchers attached recording electrodes to infants' feet at age 1 and measured their skin conductance at rest, in response to loud noises, and after encountering a scary remote-controlled robot. They also collected data on their aggressive behaviors at age 3, as rated by the infants' mothers.

The results revealed that 1 year-old infants with lower SCA at rest and during the robot encounter were more physically and verbally aggressive at age 3.

Interestingly, SCA was the only factor in the study that predicted later aggression. The other measures taken at infancy -- mothers' reports of their infants' temperament, for instance -- did not predict aggression two years later.

These findings suggest that while a physiological measure (SCA) taken in infancy predicts aggression, mothers' observations do not.

"This runs counter to what many developmental psychologists would expect, namely that a mother is the best source of information about her child," van Goozen notes.

At the same time, this research has important implications for intervention strategies:

"These findings show that it is possible to identify at-risk children long before problematic behavior is readily observable," van Goozen concludes. "Identifying precursors of disorder in the context of typical development can inform the implementation of effective prevention programs and ultimately reduce the psychological and economic costs of antisocial behavior to society."

Co-authors on this research include Erika Baker, Katherine Shelton, Eugenia Baibazarova, and Dale Hay of Cardiff University.

This research was supported by studentships from the School of Psychology, Cardiff University, and by a grant from the Medical Research Council.
