Former Senator DeMint takes center stage in immigration debate

By Caren Bohan

WASHINGTON (Reuters) - When Jim DeMint announced in December that he was leaving the U.S. Senate to head the Heritage Foundation think tank, he said he thought he could wield more influence outside rather than inside the Congress.

Any doubt about that may have been put to rest on Monday with the release of a study by the foundation lambasting a bipartisan immigration proposal in the Senate as a budget-buster that would cost taxpayers trillions of dollars.

While the report was written by a scholar, Robert Rector, the main attraction was DeMint. That was true for boosters of the study and, as it turned out, for as detractors as well, who used DeMint's name to discredit the findings.

The publicity tour started on Sunday when the former South Carolina senator plugged the Heritage study on ABC's "This Week," not normally a venue for think-tank wonks.

It continued on Monday with DeMint defending it in advance on Fox News. Hours later, DeMint presided at the news conference where the report was released.

"He obviously has some influence as a former senator," said Tevi Troy, a former deputy secretary of the Department of Health and Human Services under President George W. Bush.

Troy said the immigration fight would be an "interesting test case" of Heritage's clout since it is the first big issue it is taking on under DeMint's leadership.

Having DeMint as the star cut both ways, however. He is a long-time opponent of immigration reform and as a senator he helped kill a similar bill in 2007. Critics of the Heritage Foundation report - and there were many - used that fact to attack the study.

Among the most outspoken was Haley Barbour, the ex-governor of Mississippi and former head of the Republican National Committee. He noted pointedly on a conference call with reporters that "it was probably more than a coincidence" that Heritage, under DeMint, would be opposing the immigration bill. The study, Barbour said, "is a political document."

DeMint's "reputation as a researcher is, um, questionable," said a statement from America's Voice, a liberal advocacy group that favors the Senate legislation.

The content of the Heritage study was controversial enough. It estimated that the bill's provisions giving undocumented immigrants a 13-year path to citizenship - "amnesty" in DeMint's words - would cost $6.3 trillion over a lifetime because of government benefits that would be paid to them.

Conservative critics of the study called it deeply flawed because it failed to consider the benefits to the economy of the bipartisan immigration bill, which includes provisions sought by industry to fill high-tech and low-tech jobs that companies say are going begging.

OPENING SALVO

The foundation said it followed respected scholarly methodology in producing the study. "We are a research institution here," said Derrick Morgan, a Heritage vice president. "We can't necessarily speak to the motivations of other people. "But we very much want the fiscal costs to be part of the debate because it protects the American taxpayer."

The argument about the study, which took place just days before debate is scheduled to begin on amendments to the Senate immigration bill, marked the opening salvo in a war of talking points and studies that will play out over the next few months.

Heritage is at odds with liberal think tanks such as the Center for American Progress and also with analysts at the libertarian Cato Institute as well as some scholars at the conservative American Enterprise Institute.

The divisions mirror a split within the Republican party itself, with stalwarts such as Barbour as well as Florida Senator Marco Rubio, a rising star within the party, supporting immigration reform. Others such as Senator Jeff Sessions of Alabama and Senator Ted Cruz of Texas have lined up against it.

DeMint, a leader in the conservative Tea Party movement, is known for his outspokenness. In 2009, he helped to fire up conservative opposition to President Barack Obama's proposal to overhaul the healthcare system by declaring that the bill would Obama's Waterloo. Republicans were unable to stop the bill from becoming law.

DeMint's role is all the more interesting because of his ties to Rubio, a member of the so-called Gang of Eight senators who wrote the immigration reform bill under consideration.

DeMint was a strong supporter of Rubio's Senate candidacy in 2010 and the Florida senator, who is seen as a possible presidential candidate in 2016, has credited DeMint with helping him to win the seat.

"Immigration reform pits Rubio against mentor DeMint," said a headline on a CNN blog post.

"By the time that appeared on Monday afternoon, DeMint, unfazed, was back on television, telling Fox News: "what we need to do is put aside this whole idea of amnesty and fix our system one piece at a time."

The immigration bill, he said, "is going to be another Obamacare."

Unusual comparison nets new sleep loss marker

May 3, 2013 ? For years, Paul Shaw, PhD, a researcher at Washington University School of Medicine in St. Louis, has used what he learns in fruit flies to look for markers of sleep loss in humans.

Shaw reverses the process in a new paper, taking what he finds in humans back to the flies and gaining new insight into humans as a result: identification of a human gene that is more active after sleep deprivation.

"I'm calling the approach cross-translational research," says Shaw, associate professor of neurobiology. "Normally we go from model to human, but there's no reason why we can't take our studies from human to model and back again."

Shaw and his colleagues plan to use the information they are gaining to create a panel of tests for sleep loss. The tests may one day help assess a person's risk of falling asleep at the wheel of a car or in other dangerous contexts.

PLOS One published the results on April 24.

Scientists have known for years that sleep disorders and disruption raise blood serum levels of interleukin 6, an inflammatory immune compound. Shaw showed that this change is also detectable in saliva samples from sleep-deprived rats and humans.

Based on this link, Shaw tested the activity of other immune proteins in humans to see if any changed after sleep loss. The scientists took saliva samples from research participants after they had a normal night's sleep and after they stayed awake for 30 hours. They found two immune genes whose activity levels rose during sleep deprivation.

"Normally we would do additional human experiments to verify these links," Shaw says. "But those studies can be quite expensive, so we thought we'd test the connections in flies first."

The researchers identified genes in the fruit fly that were equivalent to the human genes, but their activity didn't increase when flies lost sleep. When they screened other, similar fruit fly genes, though, the scientists found one that did.

"We've seen this kind of switch happen before as we compared families of fly genes and families of human genes," Shaw says. "Sometimes the gene performing a particular role will change, but the task will still be handled by a gene in the same family."

When the scientists looked for the human version of the newly identified fly marker for sleep deprivation, they found ITGA5 and realized it hadn't been among the human immune genes they screened at the start of the study. Testing ITGA5 activity in the saliva samples revealed that its activity levels increased during sleep deprivation.

"We will need more time to figure out how useful this particular marker will be for detecting sleep deprivation in humans," Shaw says. "In the meantime, we're going to continue jumping between our flies and humans to maximize our insights."

Stocks gain after unemployment claims fall

NEW YORK (AP) ? The stock market is all about jobs this week.

Stocks rose Thursday after unemployment claims fell to a five-year low. A day earlier it was just the opposite; the market slumped after companies added just 119,000 jobs in April, the fewest in seven months, according to payroll processor ADP. And stocks could swing again Friday when the government's closely watched monthly employment report is released.

"Everyone is looking to the April jobs numbers," said Tyler Vernon, chief investment officer at Biltmore Capital. "People are more confident that it was an anomaly last month and are looking for some bigger numbers."

Economists forecast that the employers added 160,000 jobs last month. Stocks slumped April 5 when the government said 88,000 jobs were added, less than half the number forecast.

Signs of increased hiring have supported this year's surge in stocks and pushed the market to record highs. The run-up has started to falter in recent weeks on concerns that the global economy is slowing. More jobs should boost consumer spending, a key driver of U.S. growth.

The Dow Jones industrial average rose 130.63 points to 14,831.58 on Thursday, an increase of 0.9 percent. The index lost 138 points a day earlier. The Standard & Poor's 500 index climbed 14.89 points, or 0.9 percent, to 1,597.59, also recovering almost all of its losses from a day earlier.

Applications for unemployment benefits fell last week to 324,000, the fewest since January 2008, the Labor department reported before the market opened.

The outlook for global growth also got a boost after the European Central bank cuts its benchmark interest rate a quarter of a percentage point to 0.5 percent.

The euro fell a penny against the dollar to $1.3060. The price of gold rose $21.40, or 1.5 percent, to $1,467.60 an ounce. The price of crude oil rose $2.96, or 3.3 percent, to $93.99 a barrel.

Higher profits from CBS, Facebook and other companies also lifted stocks Thursday.

Broadcaster CBS reported a 22 percent jump in first-quarter earnings as big events like the Super Bowl pushed advertising revenue higher. Its stock rose 95 cents, or 2 percent, to $47.35.

GM rose 98 cents, or 3.2 percent, to $31.16 after it lost less money in Europe and beat Wall Street's expectations for first-quarter profit. The automaker's earnings of 67 cents a share beat the 54 cents predicted by Wall Street analysts who follow the company.

Facebook gained $1.54, or 5.6 percent, to $28.98 after its first-quarter revenue rose 38 percent, surpassing Wall Street expectations. Nearly a third of the company's advertising revenue came from mobile devices, a greater share than analysts had expected.

The social networking site bucked the trend for companies reporting in the first quarter. Most are exceeding analysts' expectations on earnings, but falling short on revenue.

"If we continue to see several more quarters like this, investors would start to get nervous," said Andrew Milligan, head of global strategy at Standard Life Investments. He says that growth needs to pick up in the major export markets, like China and Europe, for U.S. companies to maintain earnings growth.

Facebook's earnings also boosted information technology stocks. The industry rose 1.4 percent, the most of the 10 groups in the Standard & Poor's 500 index.

Technology stocks have surged in the past two weeks, after lagging the S&P 500 in the first three months of the year. Their 5.7 percent increase in 2013 still trails the 18.5 percent gain for health care companies, the best performing industry in the index.

Seagate Technology was another technology company that gained Thursday. The company, which makes hard drives, jumped $2.69, or 7.3 percent, to $39.63, even after the company reported a slump in sales and earnings. The decline wasn't as bad as analysts had expected, though, and Seagate handily beat estimates for both sales and revenue.

Earnings at companies in the S&P 500 are at record levels. They are forecast to increase by 4.4 percent in the first quarter and keep rising throughout the year, according to S&P Capital IQ data.

Gains for technology companies helped push the technology-heavy Nasdaq composite higher. The index advanced 41.49 points, or 1.3 percent, to 3,340.62.

Stocks are rebounding after a slump Wednesday, when reports of slower manufacturing growth and hiring dragged down markets. The Dow had its worst drop in two weeks. The market was down even after the Federal Reserve Bank reaffirmed its plan to continue its stimulus program, which is now five years old.

For the year, the Dow is still up 13 higher, the S&P 500 is up 12 percent.

The gains suggest that the market is getting ahead of itself, given a lackluster outlook for the economy, said Uri Landesman of Platinum Partners. He thinks the stock market is set for a pullback.

In government bond trading, the yield on the 10-year note was unchanged at 1.63 percent, matching its low for the year. Bonds have gained as inflation remains tame.

Sea surface temperatures reach highest level in 150 years on Northeast continental shelf

Apr. 26, 2013 ? Sea surface temperatures in the Northeast Shelf Large Marine Ecosystem during 2012 were the highest recorded in 150 years, according to the latest Ecosystem Advisory issued by NOAA's Northeast Fisheries Science Center (NEFSC). These high sea surface temperatures (SSTs) are the latest in a trend of above average temperature seen during the spring and summer seasons, and part of a pattern of elevated temperatures occurring in the Northwest Atlantic, but not seen elsewhere in the ocean basin over the past century.

The advisory reports on conditions in the second half of 2012.

Sea surface temperature for the Northeast Shelf Ecosystem reached a record high of 14 degrees Celsius (57.2?F) in 2012, exceeding the previous record high in 1951. Average SST has typically been lower than 12.4 C (54.3 F) over the past three decades.

Sea surface temperature in the region is based on both contemporary satellite remote-sensing data and long-term ship-board measurements, with historical SST conditions based on ship-board measurements dating back to 1854. The temperature increase in 2012 was the highest jump in temperature seen in the time series and one of only five times temperature has changed by more than 1 C (1.8 F).

The Northeast Shelf's warm water thermal habitat was also at a record high level during 2012, while cold water habitat was at a record low level. Early winter mixing of the water column went to extreme depths, which will impact the spring 2013 plankton bloom. Mixing redistributes nutrients and affects stratification of the water column as the bloom develops.

Temperature is also affecting distributions of fish and shellfish on the Northeast Shelf. The advisory provides data on changes in distribution, or shifts in the center of the population, of seven key fishery species over time. The four southern species -- black sea bass, summer flounder, longfin squid and butterfish -- all showed a northeastward or upshelf shift. American lobster has shifted upshelf over time but at a slower rate than the southern species. Atlantic cod and haddock have shifted downshelf."

"Many factors are involved in these shifts, including temperature, population size, and the distributions of both prey and predators," said Jon Hare, a scientist in the NEFSC's Oceanography Branch. A number of recent studies have documented changing distributions of fish and shellfish, further supporting NEFSC work reported in 2009 that found about half of the 36 fish stocks studied in the Northwest Atlantic Ocean, many of them commercially valuable species, have been shifting northward over the past four decades.

The Northeast U.S. Continental Shelf Large Marine Ecosystem (LME) extends from the Gulf of Maine to Cape Hatteras, North Carolina. The NEFSC has monitored this ecosystem with comprehensive sampling programs since1977. Prior to 1977, this ecosystem was monitored by the NEFSC through a series of separate, coordinated programs dating back decades.

Warming conditions on the Northeast Shelf in the spring of 2012 continued into September, with the most consistent warming conditions seen in the Gulf of Maine and on Georges Bank. Temperatures cooled by October and were below average in the Middle Atlantic Bight in November, perhaps due to Superstorm Sandy, but had returned to above average conditions by December.

"Changes in ocean temperatures and the timing and strength of spring and fall plankton blooms could affect the biological clocks of many marine species, which spawn at specific times of the year based on environmental cues like water temperature," Kevin Friedland, a scientist in the NEFSC Ecosystem Assessment Program, said. He noted that the contrast between years with, and without, a fall bloom is emerging as an important driver of the shelf's ecology. "The size of the spring plankton bloom was so large that the annual chlorophyll concentration remained high in 2012 despite low fall activity. These changes will have a profound impact throughout the ecosystem."

Michael Fogarty, who heads the Ecosystem Assessment Program, says the abundance of fish and shellfish is controlled by a complex set of factors, and that increasing temperatures in the ecosystem make it essential to monitor the distribution of many species, some of them migratory and others not.

"It isn't always easy to understand the big picture when you are looking at one specific part of it at one specific point in time," Fogarty said, a comparison similar to not seeing the forest when looking at a single tree in it. "We now have information on the ecosystem from a variety of sources collected over a long period of time, and are adding more data to clarify specific details. The data clearly show a relationship between all of these factors."

"What these latest findings mean for the Northeast Shelf ecosystem and its marine life is unknown," Fogarty said. "What is known is that the ecosystem is changing, and we need to continue monitoring and adapting to these changes."

Ecosystem advisories have been issued twice a year by the NEFSC's Ecosystem Assessment Program since 2006 as a way to routinely summarize overall conditions in the region. The reports show the effects of changing coastal and ocean temperatures on fisheries from Cape Hatteras to the Canadian border. The advisories provide a snapshot of the ecosystem for the fishery management councils and also a broad range of stakeholders from fishermen to researchers.

Military grooms new officers for war in cyberspace - PhysOrg.com

The U.S. service academies are ramping up efforts to groom a new breed of cyberspace warriors to confront increasing threats to the nation's military and civilian computer networks that control everything from electrical power grids to the banking system.

Students at the Army, Navy and Air Force academies are taking more courses and participating in elaborate cyberwarfare exercises as the military educates a generation of future commanders in the theory and practice of computer warfare.

The academies have been training cadets in cyber for more than a decade. But the effort has taken on new urgency amid warnings that hostile nations or organizations might be capable of crippling attacks on critical networks.

James Clapper, director of national intelligence, called cyberattack the top threat to national security when he presented the annual Worldwide Threat Assessment to Congress this month. "Threats are more diverse, interconnected, and viral than at any time in history," his report stated. "Destruction can be invisible, latent, and progressive."

China-based hackers have long been accused of cyber intrusions, and earlier this year the cybersecurity firm Mandiant released a report with new details allegedly linking a secret Chinese military unit to years of cyberattacks against U.S. companies. This year, The New York Times, The Wall Street Journal and The Washington Post all reported breaches in their computer systems and said they suspected Chinese hackers. China denies carrying out cyberattacks.

On Tuesday, hackers compromised Associated Press Twitter accounts and sent out a false tweet. AP quickly put out word that the report was false and that its accounts had been hacked. AP's accounts were shut down until the problem was corrected.

Once viewed as an obscure and even nerdy pursuit, cyber is now seen as one of the hottest fields in warfare?"a great career field in the future," said Ryan Zacher, a junior at the Air Force Academy outside Colorado Springs who switched from aeronautical engineering to computer science.

Last year the U.S. Naval Academy in Annapolis, Maryland began requiring freshmen to take a semester on cybersecurity, and it is adding a second required cyber course for juniors next year.

The school offered a major in cyber operations for the first time this year to the freshman class, and 33 midshipmen, or about 3 percent of the freshmen, signed up for it. Another 79 are majoring in computer engineering, information technology or computer science, bringing majors with a computer emphasis to about 10 percent of the class.

"There's a great deal of interest, much more than we could possibly, initially, entertain," said the academy's superintendent, Vice Adm. Michael Miller.

Since 2004, the Air Force Academy has offered a degree in computer science-cyberwarfare?initially called computer science-information assurance?that requires cadets to take courses in cryptology, information warfare and network security in addition to standard computer science. The academy is retooling a freshman computing course so that more than half its content is about cyberspace, and is looking into adding another cyber course.

"All of these cadets know that they are going to be on the front lines defending the nation in cyber," said Martin Carlisle, a computer science professor at the Air Force Academy and director of the school's Center for Cyberspace Research.

About 25 Air Force cadets will graduate this year with the computer science-cyberwarfare degree, and many will go on to advanced studies and work in their service's cyber headquarters or for U.S. Cyber Command at Fort Meade, Md., the Defense Department command responsible for defensive and offensive cyberwarfare.

Almost every Army cadet at the U.S. Military Academy at West Point, New York, takes two technology courses related to such topics as computer security and privacy. West Point also offers other cyber courses, and a computer security group meets weekly. One of the biggest cybersecurity challenges is keeping up with the head-spinning pace of change in the field.

"You know American history is pretty much the same" every year, said Lt. Col. David Raymond, who teaches a cybersecurity course. "In this domain, it's really tough to keep up with how this thing evolves."

In his congressional report, Clapper noted that the chance of a major attack by Russia, China or another nation with advanced cyber skills is remote outside a military conflict?but that other nations or groups could launch less sophisticated cyberattacks in hopes of provoking the United States or in retaliation for U.S. actions or policies overseas. South Korea accused North Korea of mounting a cyberattack in March that shut down thousands of computers at banks and television broadcasters.

Gen. Keith Alexander, head of U.S. Cyber Command, told Congress in March the command is creating teams to carry out both offensive and defensive operations. A spokesman said the command is drawing cyber officers from the service academies, officer schools and Reserve Officer Training Corps programs.

Teams from the three academies compete in events such as last week's National Security Agency Cyber Defense Exercise, in which they try to keep simulated computer networks running as an NSA "aggressor team" attacks. Teams from the U.S. Coast Guard and Merchant Marine academies also took part, along with graduate students from the U.S. Naval Postgraduate School and Canada's Royal Military College.

Air Force won among undergraduate schools. The Royal Military College won among graduate schools.

That hands-on experience is invaluable, said 2nd Lt. Jordan Keefer, a 2012 Air Force Academy graduate now pursuing a master's degree in cyberoperations at the Air Force Institute of Technology.

"You can't just go out there and start hacking. That's against the law," he said. The competitions, he said, "gave me actual experience defending a network, attacking a network."

Counterterrorism expert Richard Clarke, noting that really high-level computer skills are rare, suggested the military might have to re-examine some of its recruiting standards to attract the most adept cyberwarriors.

"Hackers are the 1 percent, the elite and the creators," said Clarke, who served as White House cybersecurity adviser during the Clinton administration. "I wouldn't worry a whole heck of a lot (about whether they) can they run fast or lift weights."

Cyber's appeal was enough to get Keefer to put aside his dream of becoming a fighter pilot, a job with undeniable swagger. "It's a challenge, and for people who like a challenge, it's the only place to be," Keefer said.
