Rep. Rogers: Al-Qaeda changing "communication tactics" following ...

TNW, and myself specifically, have been critical of the NSA?s telephonic and Internet data collection practices. It?s important to keep all perspectives in mind, of course, so I want to draw your attention to an op-ed by Rep. Mike Rogers, published in the Detroit Free Press.

In the article, Rep. Rogers defends the NSA?s activities, calls?Edward Snowden a felon, and states that?Al-Qaeda is changing its communication practices following the leaks. I?ll avoid providing commentary until after the Representative has had his say. Below are the key excerpts:

Neither program allows the NSA to read e-mails or listen to phone calls of American citizens. Both programs are constitutional and do not violate any American?s Fourth Amendment rights. Both are strictly overseen by the Foreign Intelligence Surveillance Court, a federal court created in 1978 to protect the rights of American citizens in the course of foreign intelligence gathering.

The first program allows the NSA to preserve a limited category of business records to help identify foreign terrorists and their plots to attack the U.S. This court-authorized program allows NSA to preserve only phone records such as the numbers dialed and the date, time and duration of calls. These records do not include the names or personal information of any American and do not include any content of calls.

The second program, known as PRISM, allows the NSA to obtain a court order to access the electronic communications of suspected foreign terrorists overseas. Because much of the world?s Internet traffic flows through U.S. infrastructure, the law allows the NSA to obtain the specific communications of foreign suspects from U.S. companies with a court order. This program does not create a ?back door? to any U.S. company?s server. This program cannot and does not monitor the communications of any U.S. citizens.

The effectiveness of these programs depends on them being kept secret from the foreign terrorists they target. It is much easier for terrorists to hide from us if they understand the sources and methods of our intelligence gathering. We have already seen al-Qaida begin to shift their communication tactics as a result of these leaks, and it will now be much harder for us to find them.

It?s interesting to note that PRISM, which sparked much of the current furor over data collection, and the phone metadata collecting practice which is now under legal challenge, are no longer the chief issues at the moment, regarding the NSA and privacy.

Other leaks detail wider NSA activity that collects information wholesale. Therefore, PRISM, as a more targeted program, is something of a canard in front of other NSA practices; to defend it and not address larger programs is to avoid the crux problem.

The AP reported recently a tract of information that details precisely the scale of the NSA?s data collection efforts, dating years into the past:

Despite that prohibition, shortly after the Sept. 11 terrorist attacks, President George W. Bush secretly authorized the NSA to plug into the fiber optic cables that enter and leave the United States, knowing it would give the government unprecedented, warrantless access to Americans? private conversations.

Tapping into those cables allows the NSA access to monitor emails, telephone calls, video chats, websites, bank transactions and more.

That specific revelation won?t come a shock to those better in the know about NSA activities. However, for the larger public, the scope of its work will certainly come as a surprise.

Here?s the nub of Rep. Roger?s argument: ?[T]hese narrowly targeted programs are legal, do not invade Americans? privacy rights, and are essential to detecting and disrupting future terrorist attacks.? In a very real way, there is a trade-off between privacy and security; we could allow for blanket surveillance and perhaps lower the incidence of terror-related activities, from sources foreign and domestic.

However, as a country, we?ve agreed to certain curbs and restrictions on the government?s ability to know what we are up to through both constitutional amendment, and the document?s implied right to privacy. We can change those elements of our laws and corpus documents. However, we owe it to ourselves to make those decisions in the open, as a society, and not by elected officials who fail to keep us in the loop on our own laws and regulations.

World looks to Bernanke to clarify stimulus plans

WASHINGTON (AP) ? Is the era of ultra-low interest rates nearing an end?

That's the question ? and the fear ? Chairman Ben Bernanke will face this week when he takes questions after a Federal Reserve policy meeting.

Financial markets have been gyrating in the 3? weeks since Bernanke told Congress the Fed might scale back its effort to keep long-term rates at record lows within "the next few meetings"? earlier than many had assumed.

Bernanke cautioned that the Fed would slow its support only if it felt confident the job market would show sustained improvement. And earlier in the day, he said the Fed must take care not to prematurely reduce its stimulus for the still-subpar economy.

Yet investors were left puzzled and spooked by a mixed message. Fear spread that the Fed would soon slow its $85 billion-a-month in bond purchases. Those purchases have been intended to hold down long-term borrowing rates to spur spending. Many worried that a pullback in the bond purchases could boost long-term rates, trigger a stock selloff and perhaps weaken the economy.

On Wednesday, when the Fed ends a two-day policy meeting with a Bernanke news conference, the financial world will be looking to the chairman to settle the confusion. What, Bernanke will likely be asked, would show sustained improvement in the job market? And when will the Fed most likely slow the pace of its bond purchases?

Last month, the U.S. economy added a solid 175,000 jobs. But the unemployment rate was 7.6 percent. Economists tend to regard the job market as healthy when unemployment is between 5 percent and 6 percent.

Since Bernanke's vague public comments May 22, the Dow Jones industrial average has fluctuated sharply and shed about 3 percent of its value. But the bigger shock has been in the bond market. The rate on the benchmark 10-year Treasury has jumped from a low of 1.63 percent in early May to 2.13 percent.

Higher rates ripple through the economy by making mortgages and other loans costlier. The average rate on the 30-year fixed mortgage, which tends to track the 10-year Treasury yield, reached 3.98 percent last week, according to Freddie Mac. That's its highest level since April 2012.

Just as cheap mortgages have helped feed a housing recovery, higher rates might slow it. Refinancings have declined since Bernanke's comments led to higher mortgage rates: Refinancings are 36 percent below their recent peak at the start of May, according to the Mortgage Bankers Association.

Compounding the confusion stirred by Bernanke's remarks have been comments from other members of the Fed's policy committee. Minutes of the previous meeting suggest a sharp division: Some, like Bernanke, still stress the need to fight high unemployment with low rates. Others warn that rates kept too low for too long raise the risk of high inflation and financial instability later.

The Fed's investment purchases have swollen its portfolio to $3.4 trillion ? a four-fold increase since before the 2008 financial crisis. Eventually, the Fed will need to gradually sell its portfolio. Doing so would likely lead to higher rates. Yet some think it would also defuse some risks to the financial system.

Alan Greenspan, who preceded Bernanke as Fed chairman for nearly two decades, said in a recent interview on CNBC, "The sooner we come to grips with this excessive level of assets on the balance sheet of the Federal Reserve ? that everybody agrees is excessive ? the better."

Economists say Bernanke will seek to clarify the Fed's message Wednesday. Yet they're unsure what he'll say.

Some think he could spell out the Fed's likely timetable for curtailing its bond purchases. The earliest the Fed is expected to announce a pullback is at its September meeting ? and only then if unemployment has declined and the economy is growing faster than its current sluggish annual pace of around 2 percent.

Other analysts think the economy will not have recovered enough by September. They believe the earliest the Fed will reduce its stimulus is at its final meeting of the year in December. Until then, they think Bernanke will seek to reassure investors that the Fed will make sure the economy has strengthened before it acts.

"The Fed has worked very hard to get stock prices and home prices rising to help the economy, and I don't think they want to back away from that in any way," said Mark Zandi, chief economist at Moody's Analytics. "I think Bernanke will deliver a strong message that the Fed is not going to taper until the job market is improving in a consistent way."

Some in this camp say the economy will continue to be held back by a Social Security tax increase that kicked in in January and by federal spending cuts that began taking effect March 1.

"There is nothing in the underlying economy that would suggest the Fed needs to change policy any time soon," said Brian Bethune, an economics professor at Gordon College in Massachusetts. "There is considerably slower growth on the radar screen and absolutely no inflation to worry about."

Indeed, the Fed's preferred gauge of inflation tied to consumer spending rose just 0.7 percent in the 12 months that ended in April? far below the Fed's 2 percent target.

In addition to a statement announcing its policy stance and Bernanke's news conference, the Fed on Wednesday will update its economic forecasts, which it does four times a year. The forecasts will be scrutinized for any hints about the timing of future Fed action.

In its most recent forecasts in March, Fed officials predicted that the economy would grow as little as 2.3 percent this year ? not enough to quickly drive down unemployment ? or as high as 2.8 percent. It forecast that the unemployment rate would dip to between 7.3 percent and 7.5 percent by year's end.

If the Fed dims its outlook for growth and employment, investors would likely read that to mean the central bank will delay any scaling back of its stimulus. But if the Fed upgrades its forecasts, that could suggest that it's moving closer to reducing its bond purchases.

Some analysts think that in his news conference, Bernanke will want to signal to investors that the Fed is moving toward at least the start of a reduced pace of bond purchases in the second half of the year. Sung Won Sohn, an economics professor at the Martin Smith School of Business at California State University, suggested one possible approach: The Fed could reduce its $85 billion a month in purchases to about $60 billion in September, then to about $35 billion early next year, then stop the purchases altogether by spring.

Even when the Fed stops buying bonds, it's expected to maintain its current holdings, which would continue to exert downward pressure on long-term rates.

Whatever guidance Bernanke offers Wednesday could help steady markets for a key reason: It will reduce uncertainty.

Margie Patel, a portfolio manager at Wells Fargo Capital Management, thinks investors will remain calm even after the Fed slows its stimulus. She noted that the economy has been improving, however gradually.

"There's no sector you can look at that's extremely dependent on the low rates for growth, even housing," she said. "If rates went up modestly, housing is still more affordable than it has been in years."

Cobb hit by line drive in Rays' win over Royals

ST. PETERSBURG, Fla. (AP) ? Tampa Bay right-hander Alex Cobb was taken off the field on a stretcher after he was hit on the right ear by a liner off the bat of Kansas City's Eric Hosmer in the fifth inning of the Rays' 5-3 win over the Royals on Saturday.

Cobb put a hand on his head after being struck. Trainers from both teams and other medical staff immediately ran onto the field. Cobb could be seen kicking his legs while being examined on the mound.

The Rays announced that Cobb remained conscious the whole time and was taken to Bayfront Medical Center in St. Petersburg for further examination.

Players on both teams had hands on their heads as a stunned silence overtook Tropicana Field after the crowd gasped when Cobb was struck.

It came a month after Blue Jays starter J.A. Happ was also struck by a liner against the Rays and suffered a skull fracture. Happ was discharged from an area hospital the following day.

The sound of the ball striking Cobb ? which sounded like a bat hitting a ball ? could be heard in the press box.

Rays players, manager Joe Maddon and pitching coach Jim Hickey gathered at the mound during the 11-minute delay. Shortstop Yunel Escobar was in squatting position looking down at the ground, while Hickey appeared at time at be nervously pacing near the mound.

It has been a tough week for Cobb, who left the team after starting Monday night's game against Boston due to the death of his grandmother. He was informed of the death after the game in which the 25-year old gave up a season-high six runs over four innings in a 10-8, 14-inning loss to the Red Sox.

Rays spokesman Rick Vaughn said all tests were normal and that Cobb suffered a mild concussion.

Tampa Bay pitcher David Price visited Cobb in the hospital and tweeted: "Cobber is way more tough than me!! Laughing at jokes and the name they gave him!! Please keep him and his family in your prayers."

Luke Scott, Matt Joyce and Evan Longoria homered for the Rays, who had lost five of six. Alex Torres (2-0) replaced Cobb and struck out four over 1 2-3 scoreless innings. Fernando Rodney pitched the ninth for his 14th save in 19 opportunities.

Joyce hit a solo homer off Jeremy Guthrie (7-4) in the fifth that put the Rays up 4-2 and ended the Royals' 13-game stretch of limiting opponents to three runs or fewer.

Guthrie gave up five runs and eight hits over seven innings.

Scott hit his first homer since May 19, a two-run drive during the third as Tampa Bay grabbed a 3-2 lead. Scott, who had make all of his 29 previous starts this season at designated hitter, started in left field with third baseman Longoria moving into the DH role.

Longoria, bothered the past two weeks by plantar fasciitis in his right foot, was the DH for the third straight game. He made it 5-2 on a sixth-inning solo homer and also had a sacrifice fly in the first.

Longoria is expected to DH again Sunday and could play in the field when the Rays start a road trip Tuesday at Boston.

The Royals took a 2-1 lead in the second when Alex Gordon walked on a 3-2 pitch with the bases loaded and Hosmer hit a sacrifice fly. Salvador Perez cut the deficit to 5-3 on a solo homer in the eighth.

Perez extended his hitting streak to 11 games with a single in the first.

NOTES: Tampa Bay LHP David Price (left triceps strain) had a 25-pitch bullpen session and could start a minor league rehab assignment Tuesday. The AL Cy Young Award winner may rejoin the Rays in late June or early July. ... Royals RHP Wade Davis (3-5) will pitch against his former team for the first time Sunday. "I'm not going to smile ... there's no smiling," Davis said. "We're trying to win games over here. We're trying to get in a good position over here." Roberto Hernandez (4-6) will start for the Rays.

WASHINGTON (AP) ? Wondering what the U.S. government might know about your phone calls and online life? And whether all of this really helps find terrorists? Good luck finding solid answers.

Americans trying to wrap their minds around two giant surveillance programs are confronted with a mishmash of leaks, changing claims and secrecy. Members of Congress complain that their constituents are baffled ? and many lawmakers admit they are, too.

Adding to the confusion and suspicion, those defending the programs ? from President Barack Obama to the nation's spy chief to lawmakers ? have sometimes mangled the facts.

Questions that could help sort things out often get the same answer: "That's classified."

"It's very, very difficult, I think, to have a transparent debate about secret programs approved by a secret court issuing secret court orders based on secret interpretations of the law," said Sen. Mark Udall, D-Colo., a long-time champion of privacy rights.

The nation's spy leaders promise to declassify more information about the programs, but say revealing too much would tip off terrorists and help them escape detection.

Only vague outlines of the two programs that suck up phone records and Internet data have been declassified since the first leaks were published last week in The Guardian and The Washington Post. There's no website, no book, no investigative report for Americans to turn to for the official facts.

That magnifies the confusion sown by misleading, retracted or inflated claims. A look at some of the misstatements:

___

THE 9/11 ARGUMENT

The government's surveillance powers were expanded after the intelligence failures of Sept. 11, 2001.

To explain why millions of telephone records are now stored in a digital library, the NSA chief raised as an example one of the 9/11 hijackers.

In a Senate hearing, Army Gen. Keith Alexander implied that had the program been around before 9/11, the intelligence community might have sifted through records of past calls to catch the hijackers before they crashed airliners into the World Trade Center and Pentagon.

He pointed to hijacker Khalid al-Mihdhar.

"We didn't have the data collected to know that he was a bad person," Alexander said.

But the U.S. did know that Mihdhar was a bad guy. The CIA knew that Mihdhar had met with other al-Qaida operatives at a January 2000 gathering in Malaysia.

The big problem was the CIA failed to immediately share what it knew about Mihdhar.

The information wasn't passed to the FBI until late August 2001. The FBI began searching for Mihdhar in early September, but it was too late.

___

THE FOILED SUBWAY BOMB

A 2009 plot to bomb the New York subways is being showcased as a triumph for expanded surveillance.

But the details are getting muddied.

First, Sen. Dianne Feinstein, the Democratic chairwoman of the Senate Intelligence Committee, credited the phone records data with thwarting al-Qaida bomber Najibullah Zazi's plan.

Then, talking points declassified by the Obama administration and circulated to lawmakers attributed the success against Zazi to a different NSA program, the one called PRISM that taps into email and Internet traffic in search of terrorists.

The use of PRISM to catch Zazi does little to resolve whether the government needs a program that collects such vast amounts of data, sometimes sweeping up information on American citizens.

Even before the post-Sept. 11 expanded surveillance, the FBI had the authority to ? and did, regularly ? monitor email accounts linked to terrorists. Before the laws changed, the government needed to get a warrant by showing that the target was a suspected member of a terrorist group. In the Zazi case, that connection already was well-established.

___

THE 'LEAST UNTRUTHFUL' ANSWER

Director of National Intelligence James Clapper describes his attempt to dodge a question as "too cute by half."

Sen. Ron Wyden, who posed the question in March, says Clapper failed to give a straight answer. Rep. Justin Amash, R-Mich., suggests Clapper's answer amounts to perjury and he should resign.

The exchange came at a Senate Intelligence Committee hearing before the phone program had been divulged.

"Does the NSA collect any type of data at all on millions or hundreds of millions of Americans?" Wyden, D-Ore., asked Clapper.

"No, sir," Clapper answered.

"It does not?" Wyden pressed.

Clapper reluctantly softened his answer somewhat: "Not wittingly," he said. "There are cases where they could, inadvertently perhaps, collect ? but not wittingly."

Turns out they do file away phone records ? not conversations, but the phone numbers of calls placed and received ? on millions of Americans.

After that leaked to the public, Clapper tried to explain his answer in an NBC News interview. "I responded," he said, "in what I thought was the most truthful, or least untruthful manner."

Wyden says he even gave Clapper a day to prepare his answer. And, Wyden says, he gave Clapper a chance to change his answer in private.

___

CONFUSION IN CONGRESS

Even one of the surveillance programs' staunchest supporters had trouble keeping the basics straight.

Explaining the programs to reporters, Sen. Lindsey Graham, R-S.C., initially described how the NSA uses pattern analysis to sort through millions of phone calls from the United States.

"You basically say, 'Computer, tell me who has called Yemen once a week for the last month,' " Graham said. "They spit out a bunch of numbers."

But intelligence officials say that doesn't happen.

They say Americans' phone records are only accessed if there is evidence connecting them to suspected terrorists ? not just a pattern of calls, such as to a certain country.

After intelligence officials objected, Graham ? a member of the Armed Services and Judiciary committees but not the Intelligence panel ? said he had misspoken.

But his earlier words reflect privacy advocates' fears about the sort of thing the government might do with its library of call records, if not now then maybe someday in the future.

___

OBAMA'S TAKE

The president tried to reassure Americans about the massive surveillance programs. But he left some misimpressions.

"With respect to the Internet and emails," Obama said, "this does not apply to U.S. citizens."

Indeed, intelligence agency leaders say that these programs can't legally target Americans. That doesn't mean their online activities won't be swept up in the surveillance net, however.

Analysts watching a suspected terrorist see that person's emails, Facebook friends and other online traffic that might include Americans.

And American communications can be accidentally captured by computer programs searching for data on terror suspects. John Negroponte, a former director of national intelligence, said such unintentionally gathered information wouldn't be kept or used by agents.

Some Congress members bristled at the way Obama described briefings available to them: "Your duly elected representatives have been consistently informed on exactly what we're doing," he said.

Sen. Mike Johanns, R-Neb., said: "The impression has been created that people (are) parked in our office giving us daily briefings on this, or monthly briefings. And that's not been the case."

At a Senate hearing Wednesday, Johanns complained: "We're all getting bombarded with questions that many of us at the rank-and-file level in the Senate cannot answer."

Professor discovers how new corals species form in the ocean

Thursday, February 7, 2013

Since the observations made by English naturalist Charles Darwin on the Galapagos Islands, researchers have been interested in how physical barriers, such as isolation on a particular island, can lead to the formation of new species through the process of natural selection. Natural selection is a process whereby heritable traits that enhance survival become more common in successive generations, while unfavorable heritable traits become less common. Over time, animals and plants that have morphologies or other attributes that enhance their suitability to a particular environment become more common and more adapted to that specific environment.

Researchers today are intimately familiar with how physical barriers and reproduction isolation can lead to the formation of new species on land, especially among plants and animals with short generation times such as insects and annual plants. Michael E. Hellberg, associate professor in the Department of Biological Sciences at LSU, however, is interested in a more obscure form of speciation: the speciation of animals in the ocean.

"Marine plants and animals can drift around in the ocean extremely long distances," Hellberg said. "So how do they specialize?"

In a recent publication in the Proceedings of the National Academy of Sciences, or PNAS, Hellberg and his graduate student Carlos Prada investigate how corals specialize to particular environments in the ocean. Corals, animals that form coral reefs and some of the most diverse ecosystems in the world, start their lifecycle with a free floating larval stage. Coral larvae can disperse vast distances in open water. Different coral species share similar geographical locations, with different species often existing only yards apart. As Prada and Hellberg propose in their recent publication, the large dispersal potential of coral larvae in open water and the proximity of different species on the ocean floor creates a mystery for researchers who study speciation. Hellberg and Prada ask, "How can new marine species emerge without obvious geographic isolation?"

When it comes to corals within the relatively small confines of the Caribbean, which spans approximately 3 million square kilometers, the key to the puzzle appears to be habitat depth in the ocean. In others words, natural selection has led to the formation of different coral species according to how deep in the ocean these different corals grow.

Prada and Hellberg study candelabrum corals of the genus Eunicea, generally known as "sea fans," for which sister species have been shown to be segregated by ocean depth. One sister species survives better in shallow waters, while the other is better adapted to deep waters. These corals, like other corals, are very slow-growing animals. In fact, sea fan corals don't reach reproduction age until they are 15-30 years old, and can continue reproducing until they are 60 or more years old. So while candelabrum coral larvae can disperse large distances from their parents, landing and beginning to grow in either shallow or deep water habitats, small differences in survival rates at different depths between the two species and long generation times can combine to produce segregation.

"When these coral larvae first settle out after dispersal, they are all mixed up," Hellberg said. "But long larvae-to-reproduction times can compound small differences in survival at different depths. By the time these corals get to reproduction age, a lot has changed."

The shallow water sea fan coral even has a different morphology than its deep water sister. The shallow water coral fans out into a wide network of branches, while the deep water coral grows tall and spindly. According to Hellberg, these differences in morphology might well be genetic, with the different corals having different protein structures and levels of expression that are better adapted to their specific water depth environment. Hellberg hopes in future research to investigate the genetic basis of these different morphologies.

In other interesting results, Prada explained how transplanting the shallow coral species to deep water environments, and vice versa, can cause the coral to take on a morphology more like that of its sister species.

"Their morphologies are not super fixed," Prada said. "But they can't change all the way to a different morphology."

Prada observed that while shallow water sea fans can become taller and more spindly when transplanted in deep water environments, they don't seem to be able to make a complete transition to the morphology of the deep water sea fan. This suggests that the two corals, while they likely had a common ancestor, have adapted genetically and biochemically to their respective water depths.

Prada did ocean dives in the Bahamas, Panama, Puerto Rico and Cura?ao to sample candelabrum coral colonies. Back in the lab, he performed tests on the coral samples' genes to determine how shallow and deep corals become genetically different.

"Normally, organisms are differentiated by geography," Prada said. "But these corals are differentiated by depth."

Prada and Hellberg's research provides new insights into how new species form in the ocean, a topic of relatively limited research as opposed to speciation of terrestrial organisms.
