(AP) ? Syria's prime minister narrowly escaped an assassination attempt in the heart of the heavily defended capital Monday, state media said, laying bare the vulnerability of President Bashar Assad's regime.

The bombing, which killed several other people, highlights an accelerating campaign targeting government officials, from mid-level civil servants to the highest echelons of the Syrian regime.

State television said Prime Minister Wael al-Halqi was not hurt in the bombing, which struck his convoy as it drove through the posh Mazzeh neighborhood ? home to embassies, government officials and business elites with close ties to the regime. Footage of the scene broadcast on state TV showed the charred hulks of cars and the burnt-out shell of a bus in a street littered with rubble.

The attack on al-Halqi punctuated a series of attacks on government officials in recent weeks. On April 18, gunmen shot dead the head of public relations at the Ministry of Social Affairs while he dined at a Mazzeh restaurant. A day later, a Syrian army colonel was killed in Damascus, and five days after that a bomb killed an official from the Electricity Ministry.

Then there are the larger attacks that have shaken the regime to its core.

Last month, a suicide bombing at a Damascus mosque killed Sheik Mohammad Said Ramadan al-Buti, a leading Sunni Muslim preacher and outspoken supporter of Assad. That followed a blast last July that killed four top regime officials, including Assad's brother-in-law and the defense minister, at the Syrian national security building in the capital.

Eager to assure the public that al-Halqi survived Monday's attack, the state-run Al-Ikhbariya station said the prime minister attended a regular weekly meeting with an economic committee immediately after the bombing. The station broadcast video of al-Halqi sitting at a table with several other officials.

Later, in its evening news program, state TV showed video of al-Halqi denouncing the attack, calling it a "terrorist and criminal act" and wishing the wounded a speedy recovery.

A government official said two people were killed and 11 wounded in the blast, while the Britain-based Syrian Observatory for Human Rights activist group put the death toll at five, including two of al-Halqi's bodyguards and one of the drivers in his convoy.

The government official spoke to The Associated Press on condition of anonymity because he was not authorized to give official statements to reporters.

The bombings and assassinations are part of the wider violence wracking Syria as the nation's conflict enters its third year. The crisis began with largely peaceful anti-government protests in March 2011, but has since morphed into a civil war that has killed more than 70,000 people, according to the United Nations.

State TV quoted Syrian Information Minister Omran al-Zoubi as saying that targeting al-Halqi, who is in charge of carrying out a political program to end the nation's crisis, shows that some in the opposition "reject a political solution."

Al-Halqi, who was appointed prime minister in August after his predecessor defected, heads a ministerial committee charged with holding a dialogue with opposition groups. The initiative is part of efforts to implement a peace plan, including a national reconciliation conference, that Assad outlined in a speech in January.

The proposal, however, has never gotten off the ground. The political opposition abroad says it will not accept anything less than Assad's departure, and roundly dismissed the president's plan as a political ploy. The myriad rebels fighting on the ground ? without a unified command ? have also rejected talks with the government as long as Assad is in power.

There was no immediate claim of responsibility for Monday's attack, but bombings like the one that struck the prime minister's convoy have been a trademark of Islamic radicals fighting in the rebel ranks, such as the al-Qaida-linked Jabhat al-Nusra.

While the rebels have wrested much of northern Syria from the regime in the past year, the government hold on Damascus is firm and regime forces have been on the offensive recently in the capital's suburbs and in the countryside near the border with Lebanon. In the northwest, regime troops recently opened up a key supply road to soldiers fighting in the embattled city of Aleppo.

As the regime has sought to shore up its strategic position, it has come under allegations of using chemical weapons on at least two occasions dating back to December.

The U.S. said last week that intelligence indicates the Syrian military has likely used sarin, a deadly nerve agent, echoing similar assessments from Israel, France and Britain. Syria's rebels accuse the regime of firing chemical weapons on at least four occasions, while the government denies the charges and says opposition fighters have used chemical agents in a bid to frame it.

At the United Nations, Secretary-General Ban Ki-moon reiterated his appeal to Syria to allow a team of experts into the country "without delay and without any conditions" to investigate allegations of chemical weapons use. He added that he takes seriously a recent U.S. intelligence report which indicates Syria has twice used chemical weapons.

The Assad government has asked for a U.N. investigation, but wants it to be limited to an incident near Aleppo in March. Ban has pushed for a broader investigation, including a December incident in the central city of Homs.

A U.N. team of experts has already begun gathering and analyzing available evidence, but Ban said onsite activities are essential if the U.N. is to establish the facts and "clear all the doubts."

Meanwhile, a new jihadi group calling itself the Ahrar al-Bekaa Brigades announced its formation and warned the pro-Syrian Lebanese militant Hezbollah group to stop intervening in the Syrian civil war or face attacks in Lebanon.

According to the SITE Intelligence Group, which tracks Islamist extremist messages, the statement was distributed on anti-Assad Facebook pages Sunday.

In the statement, the previously unheard of group claims that Hezbollah is acting on Iran's orders to "slaughter" the Syrian people. It pledged to prevent Hezbollah's intervention "with all means and ways, even if we have to move the fight to the inside of the Lebanese territory."

The Shiite Muslim Hezbollah is known to be backing regime fighters in Shiite villages near the Lebanon border against the mostly Sunni rebels fighting to topple Assad. The Syrian opposition accuses Hezbollah of taking part in the Syrian military crackdown.

Filmmakers fight bill to end subsidies | CharlotteObserver.com

RALEIGH Is ?Homeland? under threat?

It is, according to North Carolina?s film community.

Advocates of the state?s film industry say a House bill that would change the way the state subsidizes film production would essentially drive the business away.

?You?d see productions just leaving North Carolina ? including ?Homeland,?? said Aaron Syrett, director of the North Carolina Film Office.

?Homeland? is the Emmy Award winning Showtime drama shot in Charlotte and about to enter its third season. It?s one of more than 40 projects that Syrett said resulted in $376 million worth of spending and thousands of jobs last year.

Critics of incentives ? which amounted to $45 million in 2012 ? say the money could be put to better use. And they point to a legislative study that found the credit itself is responsible for a fraction of the jobs the industry claims.

?It?s not worth it to deny $45 million to public education to help one industry,? said Rep. Paul Luebke, a Durham Democrat.

Luebke is co-sponsoring a bill that would eliminate the refundable portion of the state?s film tax credit. Production companies can now claim a 25 percent tax credit up to $20 million on productions spending more than $250,000 in qualified expenses.

The bill was sent to the House Rules Committee, often a virtual graveyard. But primary co-sponsors include two Republicans from the Wilmington area ? a major film production area ? as well as GOP Speaker Pro Tem, Paul Stam of Apex.

According to the Wilmington Star-News, hundreds gathered in the city last weekend for a rally opposing the bill.

The film council says there are currently three projects shooting in the Wilmington area and five in and around Charlotte. Syrett called Charlotte ?an emerging market? for film production.

At a meeting of the film council this week, vice chair E.A. Tod Thorne of Charlotte said a film producer who had planned to shoot in Charlotte was considering filming in Georgia because of the bill.

In a statement, Twentieth Century Fox Television, which produces ?Homeland,? said the proposed changes would be ?devastating? for the series, which is about to start filming its third season.

?We?ve grown to love the talent community (in Charlotte) and many of our key personnel have now made Charlotte their permanent home,? the statement said.

?We fear that reductions in, or elimination of, the state?s film incentives could have a devastating impact on our ability to continue to produce the show at the level of quality our viewers have come to expect.?

Czechs to send funds to blast-hit Texas town

PRAGUE (AP) ? The Czech Republic plans to donate 4 million koruna (some $200,000) to help the Texas town of West recover from a devastating fertilizer plant explosion.

The government decided to the provide aid in solidarity because a significant number of people in the town of 2,700 have Czech roots. The blast damaged numerous homes in the town.

The Foreign Ministry says Czech Ambassador to the U.S. Petr Gandalovic visited West last week and talked to Texas Gov. Rick Perry, West Mayor Tommy Muska and other officials about how to help.

A ministry statement Wednesday said the money will go toward repairing property in the town.

Thousands of Czechs, mostly from the eastern part known of Moravia, settled in Texas more than 100 years ago.

Nintendo's digital game sales hit an all-time high

DNP Nintendo digital games sales more than double

Nintendo's hardware sales may be in a bit of a stupor, but its downloadable games are a different story. During today's financial results briefing, the company's president, Satoru Iwata, announced that digital sales for the 2013 fiscal year, which ended in March, cruised past ¥16 billion (around $160.9 million), more than doubling transactions from the last two years. Nintendo's frontman went on to credit the demand for downloadable game add-ons and the convenience of digital titles as contributing factors in the company's surge. Iwata also pointed out that most 3DS owners are using their systems online. This includes 87 percent of the handheld's owners in Japan and 83 percent in the US. While these numbers are impressive, the system's internet use statistics start to dwindle in Europe, where its user connectivity rate is only 57 percent. The Wii U's user base is almost as connected, with 80 percent of the platform's owners taking the system online The company's e-commerce may be thriving, but we wouldn't bet on seeing Nintendo announce a download-only console during its E3 keynote presentation.

Everybody's Doing It: Monkeys Eat What Others are Eating

Just as human travelers often adopt the local cuisine, wild monkeys learn to eat what those around them are eating, new research finds.

A study of wild vervet monkeys (Chlorocebus aethiops) in South Africa provides proof that primates other than humans adopt and conform to cultural behaviors. Given a choice between two foods, infant monkeys ate only the foods that their mothers ate. And young males that ventured to other groups soon switched to the local diet, researchers report online today (April 25) in the journal Science.

"Some of the ways of learning that we have thought were distinctly human are more broadly shared across nonhuman primates," said study co-author Andrew Whiten, a cognitive biologist at the University of St. Andrews in the United Kingdom. [Image Gallery: Adorable Vervet Monkeys Conform to Peers]

Cultural learning and conformity play central roles in human life. Whereas many studies have documented cultural transmission in lab animals, few have shown this phenomenon occurs in the wild.

A team of researchers studied four groups of wild vervet monkeys, each containing 24 to 44 individuals (109 animals in total). The team gave each group a supply of maize corn dyed pink and another dyed blue. In two groups, the blue corn tasted bad, so the animals learned to eat only the pink corn. In the other two groups, the pink corn was unpalatable, so the animals favored the blue corn.

After four to six months, the researchers replaced the bad-tasting corn with normal-tasting stuff, but the monkeys continued to eat only the color to which they had become accustomed. In one exception, a low-ranking female ate the non-preferred type of corn, probably because she couldn't get access to the preferred type.

When baby monkeys that had never tasted either color corn were allowed to feed with their mothers, the little ones ate only the color of corn their mothers ate, which was almost always the color of corn preferred by the group. Even the infant of the female who ate the unpopular color of corn copied its mother's food choice.

The infants' behavior provides an example of "potent social learning," Whiten said. Despite having no prior experience with eating the two types of corn, the babies readily adopted their mothers' dietary preference.

Next, the researchers observed what happened when young-adult males from each group migrated to another group during the mating season ? a common practice that ensures genetic diversity in vervet populations. Of the 10 males that migrated to a group with a preference for the opposite food color from their native group, seven of them chose to eat the corn that the new group preferred. When no other higher-ranking males were present to intimidate them, nine of the 10 males ate the popular color of corn.

Basically, the migrant males were conforming to fit in with their new group, the observations suggest. The males' behavior was perhaps even more surprising than the babies' behavior, because they were abandoning their prior preference in favor of the prevailing one, Whiten said.

Frans de Waal, a primatologist at Emory University's Yerkes Primate Center who was not involved in the study, called the finding striking. "It is one of the very few successful controlled experiments in the wild," de Waal said, adding that "it hints at a level of conformism most of us, until now, held not possible."

Primates aren't the only animals to learn from their peers. For example, another new study shows that whales pick up feeding techniques from their friends. Collectively, these studies suggest that culture is more widespread in the animal kingdom than once thought.

"The English Teacher" follows footsteps of "Weeds," "Nurse Jackie"

By Ellen Wulfhorst

NEW YORK (Reuters) - Fans of "Nurse Jackie," "Weeds," and "The Big C" will recognize the quirky lead of "The English Teacher" as she steps out of her straight-laced life to encounter unexpected consequences, the movie's director said in an interview.

In "The English Teacher," which has its world premiere at the Tribeca Film Festival on Friday, lead character Linda Sinclair, played by Julianne Moore, tries to mount a high school production of a play written by a former student (Michael Angarano) who has returned to his small hometown in Pennsylvania.

With the help of Nathan Lane as the high school's drama teacher and Greg Kinnear as the playwright's father, putting on the production leads almost everyone involved into trouble.

Directing the tale is Craig Zisk, who has dozens of well-regarded television series under his belt as producer or director, including "Parks and Recreation," "The Big C," "Nip/Tuck," "Weeds" and "Scrubs."

"Most of the shows that I either produced or directed feature very strong female leads," Zisk said in an interview with Reuters, ticking off the names of Mary-Louise Parker in "Weeds," Laura Linney in "The Big C," Toni Collette in "United States of Tara" and Edie Falco in "Nurse Jackie."

"With these incredibly talented strong women, I was really attracted to that when I read the script," he said.

"They are all very flawed characters," he added. "In the case of Linda, she's actually someone trying to do the right thing ... even though every time she tries to do something nice for somebody, it backfires and blows up in her face."

"The English Teacher" is Zisk's first feature film, an undertaking he said he weighed for five years before finding the right movie to make. Zisk is a four-time primetime Emmy nominee.

"I know how important the first feature is, especially for someone coming from television, because in the past there's kind of been a knock on television directors and people getting one shot," he said.

But apart from the obvious appeal of branching out, he said that making a film rather than a television show gave him the unprecedented luxury of time to prepare and an autonomy he enjoyed.

"The producers pretty much left me on my own, which was really great," Zisk said. "I feel like I made the movie I wanted to make."

Being distributed domestically by Cinedigm Entertainment Group and Tribeca Film, "The English Teacher" opens in theaters on May 17. It also can be found on-demand on television.

Sequencing the worm's genome and transcriptome opens a new chapter in the study of fundamental biological processes and animal behavior

WORCESTER, Mass. -- It has co-existed quietly with humans for centuries, slurping up the spillage in beer halls and gorging on the sour paste used to bind books. Now the tiny nematode Panagrellus redivivus (P.redivivus) has emerged from relative obscurity with the publication of its complete genetic code. Further study of this worm, which is often called the beer-mat worm or, simply, the microworm, is expected to shed new light on many aspects of animal biology, including the differences between male and female organisms and the unique adaptations of parasitic worms.

Using next-generation sequencing technologies, a research team led by Jagan Srinivasan, now an assistant professor of biology and biotechnology at Worcester Polytechnic Institute (WPI), discovered just over 24,000 putative genes encoded in the worm's DNAnearly the same number as in the human genome. The team also measured the amount and characteristics of RNA molecules transcribed from those genes to direct cellular processesthat collection of data is called the worm's transcriptome. The genome data published by Srinivasan and colleagues marks the first time a free-living nematode outside of the widely studied C. elegans immediate family has been sequenced.

The researchers detail their findings in the paper, "The Draft Genome and Transcriptome of Panagrellus redivivus Are Shaped by the Harsh Demands of a Free-Living Lifestyle," published in the April 2013 edition of the journal Genetics.

"Humans and nematodes share a common ancestor that lived in the oceans more than 600 million years ago," Srinivasan said. "Many of the basic biological processes have been conserved over the millennia and are similar in Panagrellus and humans. So we believe there is a lot to be learned from studying this organism."

Srinivasan led the P.redivivus sequencing project while working as a postdoctoral researcher at the California Institute of Technology in the laboratory of Paul Sternberg, a Howard Hughes Medical Institute investigator and the Thomas Hunt Morgan Professor of Biology at Caltech. Adler Dillman, a graduate student at Caltech, worked closely with Srinivasan on the project and shares first-author status of the new study. Sternberg is the senior author.

Srinivasan joined the WPI faculty in the fall of 2012 and has established his own research program using the microworm and its scientifically more famous cousin, Caenorhabditis elegans (C. elegans), as model systems to study the neurobiological basis of social communication and how organisms react to environmental cues.

In recent years C. elegans has emerged as a star in the biomedical research world. In 1998 it became the first multicellular organism to have its genome sequenced. The experience gained from that work was fundamental to the successful completion of the Human Genome Project. Nobel prizes in 2002, 2006, and 2008 were awarded to researchers who made extraordinary discoveries studying C. elegans.

Like C. elegans, the microworm P. redivivus is a free-living nematode found in many environments around the world. An adult microworm is about 2 millimeters long and has approximately 1,000 cells. Despite its small size, the worm is a complex organism able to do all of the things animals must do to survive. It can move, eat, reproduce, and process cues from its environment that help it forage for food, seek out mates, or react to threats. Unlike C. elegans, however, P. redivivus is a gonochoristic species, meaning it has male and female individuals who must mate to reproduce. In contrast, C. elegans has evolved to be primarily a self-fertilizing hermaphrodite, producing both eggs and sperm in the same individual. (There are some male-only C. elegans worms, but they are rare in the wild.)

"Because we see true male and female individuals, Panagrellus will be a powerful model system for studying the differences between the sexes and the processes that the organism uses to find and interact with a mate," Srinivasan said.

Both P. redivivus and C. elegans are well suited for laboratory research, Srinivasan noted. The worms are easily cultured and have a short lifecycle, growing from embryo to adult in about four days. Adults live for approximately three weeks and can produce as many as 40 offspring each day. This lifecycle makes them ideal for genetic studies. Furthermore, the worms are transparent. Under a microscope researchers can look into a worm's body and see almost every cell in the living animal. They can see the cell nuclei, tag molecules with glowing fluorescent markers, and capture images of biological processes from the moment of fertilization to maturity.

As a free-living species, the microworm is considered to be an ancestor of other small worms that have evolved into parasites and colonize specific plants or animals (including humans) to survive. Studying the differences between the microworm and parasitic species will become another important area of research, Professor Sternberg noted. "Of course we want to know more about parasitic worms, given their impact on people and the environment," Sternberg said. "To know about parasites, however, you have to know about the free-living worms to place the bizarre features of parasites into context."

The current study identified the number, location, and composition of genes and RNA transcript in the microworm, and found significant and surprising differences between the P.redivivus genome and that of C. elegans even though the worms look nearly identical to the naked eye. For example, the early analysis of the microworm genome suggests that a large collection of genes have evolved as defenses against viruses and other pathogens the worms encounter in the environmenthence the "harsh demands" of their lifestyle as referenced in the paper's title.

"Studying how the genomes differ, and what processes are driven by those differences, should prove to be insightful," Srinivasan said. "Sequencing the genome and transcriptome is an important first step in what we believe will be a rich new field of study for fundamental biological processes that control development and behavior, not only in the worms, but also in humans."

Adler Dillman, a graduate student at Caltech, worked closely with Srinivasan on the project and shares first-author status of the new study. Sternberg is the senior author.

Srinivasan joined the WPI faculty in the fall of 2012 and has established his own research program using the microworm and its scientifically more famous cousin, Caenorhabditis elegans (C. elegans), as model systems to study the neurobiological basis of social communication and how organisms react to environmental cues.

In recent years C. elegans has emerged as a star in the biomedical research world. In 1998 it became the first multicellular organism to have its genome sequenced. The experience gained from that work was fundamental to the successful completion of the Human Genome Project. Nobel prizes in 2002, 2006, and 2008 were awarded to researchers who made extraordinary discoveries studying C. elegans.

Like C. elegans, the microworm P. redivivus is a free-living nematode found in many environments around the world. An adult microworm is about 2 millimeters long and has approximately 1,000 cells. Despite its small size, the worm is a complex organism able to do all of the things animals must do to survive. It can move, eat, reproduce, and process cues from its environment that help it forage for food, seek out mates, or react to threats. Unlike C. elegans, however, P. redivivus is a gonochoristic species, meaning it has male and female individuals who must mate to reproduce. In contrast, C. elegans has evolved to be primarily a self-fertilizing hermaphrodite, producing both eggs and sperm in the same individual. (There are some male-only C. elegans worms, but they are rare in the wild.)

"Because we see true male and female individuals, Panagrellus will be a powerful model system for studying the differences between the sexes and the processes that the organism uses to find and interact with a mate," Srinivasan said.

Both P. redivivus and C. elegans are well suited for laboratory research, Srinivasan noted. The worms are easily cultured and have a short lifecycle, growing from embryo to adult in about four days. Adults live for approximately three weeks and can produce as many as 40 offspring each day. This lifecycle makes them ideal for genetic studies. Furthermore, the worms are transparent. Under a microscope researchers can look into a worm's body and see almost every cell in the living animal. They can see the cell nuclei, tag molecules with glowing fluorescent markers, and capture images of biological processes from the moment of fertilization to maturity.

As a free-living species, the microworm is considered to be an ancestor of other small worms that have evolved into parasites and colonize specific plants or animals (including humans) to survive. Studying the differences between the microworm and parasitic species will become another important area of research, Professor Sternberg noted. "Of course we want to know more about parasitic worms, given their impact on people and the environment," Sternberg said. "To know about parasites, however, you have to know about the free-living worms to place the bizarre features of parasites into context."

The current study identified the number, location, and composition of genes and RNA transcript in the microworm, and found significant and surprising differences between the P.redivivus genome and that of C. elegans even though the worms look nearly identical to the naked eye. For example, the early analysis of the microworm genome suggests that a large collection of genes have evolved as defenses against viruses and other pathogens the worms encounter in the environmenthence the "harsh demands" of their lifestyle as referenced in the paper's title.

"Studying how the genomes differ, and what processes are driven by those differences, should prove to be insightful," Srinivasan said. "Sequencing the genome and transcriptome is an important first step in what we believe will be a rich new field of study for fundamental biological processes that control development and behavior, not only in the worms, but also in humans."

Senate bill ends air traffic controller furloughs

WASHINGTON (AP) ? With flight delays mounting, the Senate approved hurry-up legislation Thursday night to end air traffic controller furloughs blamed for inconveniencing large numbers of travelers.

A House vote on the measure was expected as early as Friday, with lawmakers eager to embark on a weeklong vacation.

Under the legislation, the Federal Aviation Administration would gain authority to transfer up to $253 million from accounts that are flush into other programs, to "prevent reduced operations and staffing" through the Sept. 30 end of the fiscal year.

In addition to restoring full staffing by controllers, Senate officials said the available funds should be ample enough to prevent the closure of small airport towers around the country. The FAA has said it will shut the facilities as it makes its share of $85 billion in across-the-board spending cuts that took effect last month at numerous government agencies.

The Senate acted as the FAA said there had been at least 863 flights delayed on Wednesday "attributable to staffing reductions resulting from the furlough."

There was no immediate reaction at the White House, although administration officials participated in the negotiations that led to the deal and evidently registered no objections.

Sen. Susan Collins, R-Maine, a key participant in the talks, said the legislation would "prevent what otherwise would have been intolerable delays in the air travel system, inconveniencing travelers and hurting the economy."

Senate approval followed several hours of pressure-filled, closed-door negotiations, and came after most senators had departed the Capitol on the assumption that the talks had fallen short.

Officials said a small group of senators insisted on a last-ditch effort at an agreement before Congress adjourned for a vacation that could have become politically problematic if the flight delays continued.

"I want to do it right now. There are other senators you'd have to ask what the hang-up is," Sen. Mark Udall, D-Colo., said at a point when it appeared no compromise would emerge.

For the White House and Senate Democrats, the discussions on legislation relating to one relatively small slice of the $85 billion in spending cuts marked a shift in position in a long-running struggle with Republicans over budget issues. Similarly, the turn of events marked at least modest vindication of a decision by the House GOP last winter to finesse some budget struggles in order to focus public attention on the across-the-board cuts in hopes they would gain leverage over President Barack Obama.

The Professional Aviation Safety Specialists, a union that represents FAA employees, reported a number of incidents it said were due to the furloughs.

In one case, it said several flights headed for Long Island MacArthur Airport in New York were diverted on Wednesday when a piece of equipment failed. "While the policy for this equipment is immediate restoral, due to sequestration and furloughs it was changed to next-day restoral," the union said.

It added it was "learning of additional impacts nationwide, including open watches, increased restoration times, delays resulting from insufficient funding for parts and equipment, modernization delays, missed or deferred preventative maintenance, and reduced redundancy."

The airlines, too, were pressing Congress to restore the FAA to full staffing.

In an interview Wednesday, Robert Isom, chief operations officer of US Airways, likened the furloughs to a "wildcat regulatory action."

He added, "In the airline business, you try to eliminate uncertainty. Some factors you can't control, like weather. It (the FAA issue) is worse than the weather."

In a shift, first the White House and then senior Democratic lawmakers have signaled a willingness in the past two days to support legislation that alleviates the budget crunch at the FAA, while leaving the balance of the $85 billion to remain in effect.

Obama favors a comprehensive agreement that replaces the entire $85 billion in across-the-board cuts as part of a broader deficit-reduction deal that includes higher taxes and spending cuts.

One Senate Democrat, Sen. Patty Murray of Washington, noted that without the type of comprehensive deficit deal that Obama favors, a bill that eases the spending crunch at the FAA would inevitably be followed by other single-issue measures. She listed funding at the National Institutes of Health as one example, and cuts that cause furloughs of civilians who work at military hospitals as a second.

At the same time, Democratic aides said resolve had crumbled under the weight of widespread delays for the traveling public and pressure from the airlines.

Sen. John Thune, R-S.D., involved in the discussions, said the issue was big enough so "most people want to find a solution as long as it doesn't spend any more money."

Officials estimate it would cost slightly more than $200 million to restore air traffic controllers to full staffing, and another $50 million to keep open smaller air traffic towers around the country that the FAA has proposed closing.

Across the Capitol, the chairman of the House Transportation Committee, Rep. Bill Shuster, R-Pa., said, "We're willing to look at what the Senate's going to propose."

He said he believes the FAA has the authority it needs under existing law to shift funds and end the furloughs of air traffic controllers, and any legislation should be "very, very limited" and direct the agency to use the flexibility it already has.

In a reflection of the political undercurrents, another House Republican, Rep. James Lankford of Oklahoma, said FAA employees "are being used as pawns by this (Obama) administration to be able to implement the maximum amount of pain on the American people when it does not have to be this way."

The White House and congressional Democrats vociferously dispute such claims.

Swype Launches on Google Play, Adds Dragon Dictation for Voice-to-Text

Android: Swype, one of our favorite Android keyboards, finally shed its long-held beta tag this morning and made its way over to Google Play, where it's available for $1. The official version comes bundled with Dragon Dictation for enhanced voice-to-text, and adds a few new features for the typo-prone.

If you use voice-to-text with Swype, there's a lot to like about the update. The latest version adds support for national and regional dialects in various languages, and comes bundled with Dragon Dictation's own speech-to-text engine so it can quickly recognize words as you say them (and bypasses Google's speech-to-text feature entirely). Swype's "smart edit" feature has been improved so you can tap a word to immediately edit it as opposed to just move the cursor there. The new "smart touch" feature aims to learn from your most commonly corrected typos so it can predict and correct them before you have to.

Swype is available now at Google Play for $1. It's no longer free like it was in beta, but it is more affordable than the community favorite, SwiftKey. The $1 price is a "limited time offer," and Swype isn't saying when that limited time expires or what the full price will be, so if you want it, grab it now.

Argentina's 'Grandmothers' seek pope's assistance

VATICAN CITY (AP) ? Members of the Argentine human rights group "Grandmothers of the Plaza de Mayo" have asked Pope Francis for help finding still-missing children taken from political prisoners during the country's 1979-83 military dictatorship.

Estela de Carlotto, president of the group, met briefly with the Argentine pope after Wednesday's general audience in St. Peter's Square. She handed him a written request that he authorize the opening of archives from the Vatican and the Catholic Church in Argentina in hopes of finding clues about the whereabouts of the children.

The organization estimates that around 500 babies were taken from their mothers while they were detained by the military.

De Carlotto told reporters after the meeting that Francis had told her: "'You can count on me. You can count on us.'"

Broadening the Window ? Aligning Indicators with Correct Holding ...

One of the biggest problems with value is the time it takes to work itself out. ?Over, and under valued securities and markets can stay stubbornly mispriced for years, or even decades. ?My favorite grandaddy of all bubbles, Japan, took about 20 years to get back to normal valuation. ?And even now the stock market is down 30% from all time real highs (including dividends).

One popular criticism of the valuation models that Hussman, Gray, Buffett, Shiller, Grantham, and Philbrick et all propose is that they tend to work over 5-15 years. ?Many conclude that they are then worthless as most people are trading on shorter time frames etc. ?It doesn?t matter if it is PE, CAPE, Tobin?s Q, dividend yield or mkt cap to GDP, most don?t work that great in the short term.

(Note: ?Our Global Value paper introduces another element, and that is relative valuation, which was shown to work great on much shorter time frames.)

So what is a simple answer to this criticism? ?Simple: ?hold the position longer.

Below we set out to test a very simple system. ?The goal is to have a maximum allocation at cheap secular lows, and a minimum allocation at secular, expensive highs.

We divide the portfolio into five buckets of 20% each. ?Each bucket can be anywhere from 0-100% invested in stocks, and the remainder is in 10 year bonds. ?Therefore, the entire portfolio can be 0-100% invested in stocks or bonds.

Rules:

Each year only update one bucket. ?

If CAPE < 10, 100% of that bucket is in stocks. 0% in bonds. ?Hold that position for 5 years.

If CAPE < 15, 75% of that bucket is in stocks. ?25% in bonds. ?Hold that position for 5 years.

If CAPE < 20, 50% of that bucket is in stocks. ?50% in bonds. ?Hold that position for 5 years.

If CAPE < 25, 25% of that bucket is in stocks. ?75% in bonds. ?Hold that position for 5 years.

If CAPE > 30, 0% of that bucket is in stocks. ?100% in bonds. ?Hold that position for 5 years.

Next year, repeat with the next bucket, so that each year you are updating just 20% of the portfolio (talk about lazy portfolios!)

(Note: ?These cutoffs and % were picked out of a hat. ?I?m sure there are better parameters, such as holding for 7-10 years.)

This way you have a portfolio that matches the holding period with the intended indicator horizon. ?More importantly, how does it work? ?(CAPE is the above strategy, not the CAPE strategy from the paper. 10 SMA is the moving average model from our QTAA paper. ?)

Not bad ? nice reductions in volatility and drawdowns. ?I?m sure you could tweak the parameters with longer holding periods as well as better CAPE cutoffs, as well as even potentially using leverage and shorting. ?Even better would be to use all of the global markets instead of just one.

Will try and write up in a longer paper at some point?readers, feel free to play around with the Shiller data on your own and report back! ?

Penske Racing to plead case to appeal panel May 1

CHARLOTTE, N.C. (AP) ? Penske Racing will take its appeal of penalties and fines against defending champion Brad Keselowski and teammate Joey Logano before a three-member NASCAR panel next week.

NASCAR selects the panel from a list of 48 people ? former car owners, crew chiefs and drivers, as well as current track promoters and industry veterans. Their identities will not be revealed until after their decision, which can be appealed to NASCAR chief appellate officer John Middlebrook. The May 1 appeal will be conducted at the Research and Development Center in Concord.

The penalties have been one of the biggest stories of the season so far. NASCAR seized parts from the rear suspensions of both Penske cars during pre-race inspections at Texas, accusing the team of using unapproved parts in the rear housing.

NASCAR docked 25 points each from Keselowski and Logano in the driver and owner standings, fined crew chiefs Paul Wolfe and Todd Gordon $100,000 each, and suspended Wolfe, Gordon, car chiefs Jerry Kelley and Raymond Fox, engineers Brian Wilson and Samuel Stanley and Penske competition director Travis Geisler for six points races.

All seven suspended employees were put on probation through Dec. 31. Penske officials say they are concerned that's more than double the probation any previous infraction received.

Team owner Roger Penske told The Associated Press the parts were approved, but NASCAR alleged they had been modified before use.

"NASCAR has approved parts and unapproved parts. The parts that we had were approved parts, they are concerned that we modified them. That's where the discussion is," he said. "From an overall standpoint, NASCAR felt what we had provided them for approval, then these parts were different during the inspection process."

Penske also said the team was working in a gray area of the rule book.

"I certainly don't think it's cheating," Penske said. "You are looking at the rules and you are working in a gray area. We all work in the gray areas. We're trying to be as competitive as we can be, we've got very creative minds and it takes a lot of creative minds to be competitive. There are many different areas we are all working on. We just looked at a particular rule that maybe NASCAR has a different view of. Now we'll get a chance to have an unbiased panel look at it."

Penske President Tim Cindric researched and found the three-member appeals panel has not overturned a NASCAR penalty regarding body infractions in the last three years. But, crew members are allowed to work during the appeal, and teams use the time to restructure and prepare for when the penalties are enforced.

Last year, Middlebrook overturned a six-race suspension for Hendrick Motorsports crew chief Chad Knaus and restored 25 points for five-time champion Jimmie Johnson.

Knaus had been punished for allegedly modifying sheet metal on Johnson's car at Daytona. Middlebrook left intact the $100,000 fine against Knaus.

This time, NASCAR has not revealed many details of its case against Penske.

Teams very much were manipulating the rear suspensions of their cars last year, and NASCAR slowly addressed the issue through a series of technical bulletins issued over the course of the season. The rule book was specifically tightened this season, with added language to the passage demanding that all suspension systems and components must be presented "in a completed form/assembly" prior to being used in competition.

A second new passage clearly states, "all front end and rear end suspension mounts and mounting hardware must not allow movement or realignment of any suspension component beyond normal rotation or suspension travel." That puts in writing that NASCAR will not tolerate teams altering the skew of the rear ends the way they did a year ago.

Penske said there was no prior warning from NASCAR that the team was potentially in violation of the rules, and that Logano's car had already cleared tech at Texas before inspectors called him back after taking parts from Keselowski's car. Logano barely made the start of the race.

Gut Microbe Makes Diesel Biofuel

Welding bits and pieces from various microbes and the camphor tree into the genetic code of Escherichia coli has allowed scientists to convince the stomach bug to produce hydrocarbons, rather than sickness or more E. coli. The gut microbe can now replicate the molecules, more commonly known as diesel, that burn predominantly in big trucks and other powerful moving machines. "We wanted to make biofuels that could be used directly with existing engines to completely replace fossil fuels," explains biologist John Love of the University of Exeter in England, who led the research into fuels. "Our next step will be to try to develop a bacterium that could be deployed industrially." Love?s work was published April 22 in Proceedings of the National Academy of Sciences. That means harnessing E. coli's already high tolerance for harsh conditions, such as the high acidity and warmth of the human digestive tract. That hardiness also seems to be helping the bacterium survive its own production of such longer-chain hydrocarbons, which could have proved toxic to the microbes, in the way brewer's yeast cells are killed off by the alcohol they ferment. The engineered E. coli used genetic code from the insect pathogen Photorhabdus luminescens and from the cyanobacterium Nostoc punctiforme as well as its fellow gut microbe Bacillus subtilis to make the fuel molecules from fatty acids, along with a gene from the camphor tree?Cinamomum camphora?to cut the resulting hydrocarbon to the right length. The E. coli are currently fed on sugar and yeast extract, which suggests that the resulting fuel would be expensive compared with the kind refined from oil found in the ground. "We are hopeful that we could change their diet to something less valuable to humanity," Love suggests. "For example, organic wastes from agriculture or even sewage." Exactly how the E. coli microbes expel the diesel fuel molecules is unknown at this point. The researchers have found them floating in the growth medium, suggesting the microbes are somehow secreting the hydrocarbons from their cells once produced. "We don't know how they get there yet," Love admits. But that may solve a problem posed to other would-be biofuels produced in microbes; algal oils have proved difficult to extract cheaply and effectively from inside the algae themselves, among other challenges. Besides a better grasp of the process itself, fine-tuning the genetic engineering may one day yield other useful hydrocarbons, such as jet fuel or even gasoline (a short-chained hydrocarbon). Similar work at the University of California, Berkeley, has tinkered with E. coli genetics to allow the bacteria to digest the inedible parts of plants known as cellulose and turn them into microbial diesel that can be used in place of fossil-fuel diesel or other useful hydrocarbons. And E. coli has been harnessed in the past to make specialty oils for cosmetics; the company Amyris makes the moisturizing oil known as squalane from E. coli fed sugarcane and grown in vats in Brazil. The synthetic biologists at Amyris have also coaxed yeast to produce the antimalarial drug artemisinin, a technology that is currently being commercialized with drugmaker Sanofi. Regardless, industrial-scale fuel production from microbes remains a much tougher proposition than making specialty oils or medicines, given the low cost and high volumes required to compete with the fuels made from fossil sources. "Fuel is actually a lot cheaper than artemisinin, so it has to be made in significantly larger quantities," Love notes. "That in itself is a challenge."

'This stuff is really cool': Obama goes into high gear at White House science fair

Saying "this stuff is really cool," President Obama praised the science projects from some high-achieving students at the third White House science fair. NBC's Peter Alexander reports.????

By Darlene Superville, The Associated Press

WASHINGTON ??It was an offer President Barack Obama couldn't refuse.

"You're welcome to try this out if you like," the Oakland Park, Fla., high school student said.

With that, a president who often laments a lifestyle that denies him the pleasure of driving eagerly hopped on the blue-and-silver bicycle in his dark blue suit and pedaled away ??never mind that the machinery didn't take him anywhere.

"Only because these guys really want this," Obama said, gesturing to the small group of reporters and photographers who were brought to a White House garden on Monday to watch the president go from exhibit to exhibit at his third White House science fair.

He said afterward that the science fair is "one of my favorite events during the course of the year."


As Obama pedaled, Payton Karr and Kiona Elliot, classmates at Northeast High School, explained their pedal-powered water filtration system. The collapsible, transportable emergency water-sanitation station filters E. coli and other harmful pathogens from contaminated water. During emergencies, the device can be assembled and broken down in less than an hour, and can produce enough water for 20 to 30 people during a 15-hour period.

Karr and Elliot were among some 30 student teams that were invited to the White House to show off projects that won them top honors in science, technology, engineering and math competitions around the country.

President Barack Obama views the winning entry in the BEST Robotics category with students from St. Vincent de Paul Middle School in Theodore, Ala., as he hosts the White House science fair in the State Dining Room at the White House. The "Vator" robot is designed to mimic a space elevator by lifting cargo up a 10-foot pole.

Rockets, robots rule
Rockets and robots were among the exhibits, too, along with a fully functioning prosthetic arm that 17-year-old Easton LaChapelle, of Mancos, Colo., made mostly with parts generated from a 3-D printer. He said it cost just a few hundred dollars to make, far less than the $80,000 replacement arm he said had inspired him.

The arm apparently functioned up until a few minutes before Obama stopped at Easton's exhibit in the State Dining Room. Easton told Obama that he'd planned for the prosthetic arm to shake the president's hand. Obama shook hands with the disembodied arm anyway, "because it was working," he said.

Three pint-sized students from Flippen Elementary School in McDonough, Ga., told Obama about the "Cool Pads" they created to help football players stay cool on the field. Evan Jackson, 10, Alec Jackson, 8, and Caleb Robinson, 8, developed the pads for the shoulders, helmet, armpits and groin with built-in temperature sensors to help keep players from overheating. Gatorade is in there, too, so players don't have to leave the field to hydrate.

Obama called their invention "pretty spiffy."

During more formal remarks after he visited a total of a dozen exhibits, Obama praised the students and their projects, which included new ways to detect cancer, create alternatives to burning wood for fuel and breeding new types of algae.

"Young people like these have to make you hopeful about the future of our country," he said.

AmeriCorps effort
Obama also announced a new effort to link AmeriCorps national service members with nonprofit groups that promote science, technology, engineering and math. Since taking office in 2009, Obama has been pushing to increase the number of students, including girls, and teachers who pursue these fields.

He also saw the rocket built by Darius Hooker, 19, of Memphis, Tenn., and his high-school classmate Wesley Carter that propelled eggs more than 800 feet into the air and then brought them down unbroken in less than a minute.

"Did the eggs come down OK?" Obama asked.

Hooker said in a telephone interview afterward that he was always interested in "anything that goes up" and that he now thinks of himself as a role model.

"We motivate a lot of people that's our age, younger than us and older than us," he said. Hooker is currently studying for a license in aircraft mechanics at Tennessee Technology Center in Memphis.
