Apple's Jony Ive Said To Be Bringing The Flat Design Fad To iOS 7 With Visual Overhaul

Screen Shot 2013-04-29 at 4.54.36 PMiOS 7 is probably right around the corner, at least as a preview coming at Apple's Worldwide Developer's Conference in June, and it looks like it might be the most exciting change to Apple's mobile OS we've seen in a long time, at least on the surface. iOS 7 will get a flat visual look, which is all the rage these days, at the hands of Apple's chief design guru Jony Ive, according to a new report by 9to5Mac. The blog's sources say that it's "very, very flat," losing any evidence of computer-generated shine, glare or the skeuomorphism reportedly favored by deposed iOS chief Scott Forstall.

BLOOMINGTON, Ind. -- A team of American and Italian neuroscientists has identified a cellular change in the brain that accompanies obesity. The findings could explain the body's tendency to maintain undesirable weight levels, rather than an ideal weight, and identify possible targets for pharmacological efforts to address obesity.

The findings, published in the Proceedings of the National Academy of Sciences Early Edition this week, identify a switch that occurs in neurons within the hypothalamus. The switch involves receptors that trigger or inhibit the release of the orexin A peptide, which stimulates the appetite, among other behaviors. In normal-weight mice, activation of this receptor decreases orexin A release. In obese mice, activation of this receptor stimulates orexin A release.

"The striking finding is that you have a massive shift of receptors from one set of nerve endings impinging on these neurons to another set," said Ken Mackie, professor in the Department of Psychological and Brain Sciences in the College of Arts and Sciences at IU Bloomington. "Before, activating this receptor inhibited the secretion of orexin; now it promotes it. This identifies potential targets where an intervention could influence obesity."

The work is part of a longstanding collaboration between Mackie's team at the Gill Center for Biomolecular Science at IU Bloomington and Vincenzo Di Marzo's team at the Institute of Biomolecular Chemistry in Pozzuoli, Italy. Both teams study the endocannabinoid system, which is composed of receptors and signaling chemicals that occur naturally in the brain and have similarities to the active ingredients in cannabis, or marijuana. This neurochemical system is involved in a variety of physiological processes, including appetite, pain, mood, stress responses and memory.

Food consumption is controlled in part by the hypothalamus, a portion of the brain that regulates many essential behaviors. Like other important body systems, food consumption is regulated by multiple neurochemical systems, including the endocannabinoid system, representing what Mackie describes as a "balance of a very fine web of regulatory networks."

An emerging idea, Mackie said, is that this network is reset during obesity so that food consumption matches maintenance of current weight, not a person's ideal weight. Thus, an obese individual who loses weight finds it difficult to keep the weight off, as the brain signals the body to eat more in an attempt to return to the heavier weight.

Using mice, this study found that in obesity, CB1 cannabinoid receptors become enriched on the nerve terminals that normally inhibit orexin neuron activity, and the orexin neurons produce more of the endocannabinoids to activate these receptors. Activating these CB1 receptors decreases inhibition of the orexin neurons, increasing orexin A release and food consumption.

"This study identifies a mechanism for the body's ongoing tendency to return to the heavier weight," Mackie said.

The researchers conducted several experiments with mice to understand how this change takes place. They uncovered a role of leptin, a key hormone made by fat cells that influences metabolism, hunger and food consumption. Obesity causes leptin levels to be chronically high, making brain cells less sensitive to its actions, which contributes to the molecular switch that leads to the overproduction of orexin.

Egypt delegation talks Syria with Iranian leaders

TEHRAN, Iran (AP) ? Iran's state TV is reporting an Egyptian presidential delegation has discussed the Syrian crisis with the leaders of Iran, the key regional ally of Syria's President Bashar Assad.

The report said Egyptian presidential adviser for foreign affairs Essam Haddad met Iranian President Mahmoud Ahmadinejad, who called for a quick settlement of the crisis based on "talk and understanding."

Another report by the semi-official ISNA news agency said the Egyptian delegation also met Iran's Supreme Leader Ayatollah Ali Khamenei, who has final say on all state matters. Khamenei has repeatedly voiced support for Assad.

The report said the two sides also discussed bilateral issues.

Egypt, alongside Iran, Saudi Arabia and Turkey are members of a regional panel aimed at bringing an end to Syria's civil war in a peaceful way.

Loans borrowed against pensions squeeze retirees

To retirees, the offers can sound like the answer to every money worry: convert tomorrow?s pension checks into today?s hard cash.

But these offers, known as pension advances, are having devastating financial consequences for a growing number of older Americans, threatening their retirement savings and plunging them further into debt. The advances, federal and state authorities say, are not advances at all, but carefully disguised loans that require borrowers to sign over all or part of their monthly pension checks. They carry interest rates that are often many times higher than those on credit cards.

In lean economic times, people with public pensions ? military veterans, teachers, firefighters, police officers and others ? are being courted particularly aggressively by pension-advance companies, which operate largely outside of state and federal banking regulations, but are now drawing scrutiny from Congress and the Consumer Financial Protection Bureau.

The pitches come mostly via the Web or ads in local circulars.

?Convert your pension into CASH,? LumpSum Pension Advance, of Irvine, Calif., says on its Web site. ?Banks are hiding,? says Pension Funding L.L.C., of Huntington Beach, Calif., on its Web site, signaling the paucity of credit. ?But you do have your pension benefits.?

Another ad on that Web site is directed at military veterans: ?You?ve put your life on the line for Americans to protect our way of life. You deserve to do something important for yourself.?

A review by The New York Times of more than two dozen contracts for pension-based loans found that after factoring in various fees, the effective interest rates ranged from 27 percent to 106 percent ? information not disclosed in the ads or in the contracts themselves. Furthermore, to qualify for one of the loans, borrowers are sometimes required to take out a life insurance policy that names the lender as the sole beneficiary.

LumpSum Pension Advance and Pension Funding did not return calls and e-mails for comment.

While it is difficult to say precisely how many financially struggling people have taken out pension loans, legal aid offices in Arizona, California, Florida and New York say they have recently encountered a surge in complaints from retirees who have run into trouble with the loans.

Ronald E. Govan, a Marine Corps veteran in Snellville, Ga., paid an interest rate of more than 36 percent on a pension-based loan. He said he was enraged that veterans were being targeted by the firm, Pensions, Annuities & Settlements, which did not return calls for comment.

?I served for this country,? said Mr. Govan, a Vietnam veteran, ?and this is what I get in return.?

The allure of borrowing against pensions underscores an abrupt reversal in the financial fortunes of many retirees in recent years, as well as the efforts by a number of financial firms, including payday lenders and debt collectors, to market directly to them.

The pension-advance firms geared up before the financial crisis to woo a vast and wealthy generation of Americans heading for retirement. Before the housing bust and recession forced many people to defer retirement and to run up debt, lenders marketed the pension-based loan largely to military members as a risk-free option for older Americans looking to take a dream vacation or even buy a yacht. ?Splurge,? one advertisement in 2004 suggested.

Now, pension-advance firms are repositioning themselves to appeal to people in and out of the military who need cash to cover basic living expenses, according to interviews with borrowers, lawyers, regulators and advocates for the elderly.

?The cost of these pension transactions can be astronomically high,? said Stuart Rossman, a lawyer with the National Consumer Law Center, an advocacy group that works on issues of economic justice for low-income people.

?But there is profit to be made on older Americans? financial pain.?

The oldest members of the baby boom generation became eligible for Social Security during the recent housing bust and recession, and many nearing retirement age watched their investments plummet in value. Some are now sliding deep into debt to make ends meet.

The pitches for pension loans emphasize how difficult it can be for retirees with scant savings and checkered credit histories to borrow money, especially because banks typically do not count pension income when considering loan applications.

?The result often leaves retired pensioners viewed like other unqualified borrowers,? one of the lenders, DFR Pension Funding, says on its Web site. That, the firm says, ?can make the ?golden years? not so golden.?

Faster rising debt
The combined debt of Americans from the ages of 65 to 74 is rising faster than that of any other age group, according to data from the Federal Reserve. For households led by people 65 and older, median debt levels have surged more than 50 percent, rising from $12,000 in 2000 to $26,000 in 2011, according to the latest data available from the Census Bureau.

While American adults of all ages ran up debt in good times, older Americans today are shouldering unusually heavy burdens. According to a 2012 study by Demos, a liberal-leaning public policy organization, households headed by people 50 and older have an average balance of more than $8,000 on their credit cards.

Meanwhile, households headed by people age 75 and older devoted 7.1 percent of their total income to debt payments in 2010, up from 4.5 percent in 2007, according to the Employee Benefit Research Institute.

Financial products like pension advances, which promise quick cash, appear especially enticing because their long-term costs are largely hidden from the borrowers.

Federal and state regulators are spotting fresh examples of abuse, and both the Consumer Financial Protection Bureau and the Senate?s Committee on Health, Education, Labor and Pensions are examining these loans, according to people with knowledge of the matter.

Though the firms are not directly regulated by states, officials from the California Department of Corporations, the state?s top financial services regulator, filed a desist-and-refrain order against a pension-advance firm in 2011 for failing to disclose critical information to investors.

That firm has since filed for bankruptcy, but a department spokesman said it remained watchful of pension-advance products.

?As the state regulator charged with protecting investors, we are aware of this type of offer and are very concerned with the companies that abuse it to defraud people,? said the spokesman, Mark Leyes.

Borrowing against pensions can help some retirees, elder-care lawyers say. But, like payday loans, which are commonly aimed at lower-income borrowers, pension loans can turn ruinous for people who are already financially vulnerable, because of the loans? high costs.

Some of the concern on abuse focuses on service members. Last year, more than 2.1 million military retirees received pensions, along with roughly 2.6 million federal employees, according to the Congressional Budget Office.

Lawyers for service members argue that pension lending flouts federal laws that restrict how military pensions can be used.

Mr. Govan, the retired Marine, considered himself a credit ?outcast? after his credit score was battered by a foreclosure in 2008 and a personal bankruptcy in 2010.

Unable to get a bank loan or credit card to supplement his pension income, Mr. Govan, now 59, applied for a payday loan online to pay for repairs to his truck.

Days later, he received a solicitation by e-mail from Pensions, Annuities & Settlements, based in Wilmington, Del.

Mr. Govan said the offer of quick, seemingly easy cash sounded too good to refuse. He said he agreed to sign over $353 a month of his $1,033 monthly disability pension for five years in exchange for $10,000 in cash up front. Those terms, including fees and finance charges, work out to an effective annual interest rate of more than 36 percent. After Mr. Govan belatedly did the math, he was shocked.

?It?s just wrong,? said Mr. Govan, who filed a federal lawsuit in February that raises questions about the costs of the loan.

Pitches to military
Pitches to military members must sidestep a federal law that prevents veterans from automatically turning over pension payments to third parties. Pension-advance firms encourage veterans to establish separate bank accounts controlled by the firms where pension payments are deposited first and then sent to the lenders. Lawyers for retirees have challenged the pension-advance firms in courts across the United States, claiming that they illegally seize military members? pensions and violate state limits on interest rates.

To circumvent state usury laws that cap loan rates, some pension advance firms insist their products are advances, not loans, according to the firms? Web sites and federal and state lawsuits. On its Web site, Pension Funding asks, ?Is this a loan against my pension?? The answer, it says, is no. ?It is an advance, not a loan,? the site says.

The advance firms have evolved from a range of different lenders; some made loans against class-action settlements, while others were subprime lenders that made installment and other short-term loans.

The bankrupt firm in California, Structured Investments, has been dogged by legal challenges virtually from the start. The firm was founded in 1996 by Ronald P. Steinberg and Steven P. Covey, an Army veteran who had been convicted of felony bank fraud in 1994, according to court records.

To attract investors, the firm promised an 8 percent return and ?an opportunity to own a cash stream of payments generated from U.S. military service persons,? according to the California Department of Corporations. Mr. Covey, according to company registration records, is also associated with Pension Funding L.L.C. Neither Mr. Covey nor Mr. Steinberg returned calls for comment. In 2011, a California judge ordered Structured Investments to pay $2.9 million to 61 veterans who had filed a class action.

But the veterans, among them Daryl Henry, retired Navy disbursing clerk, first class, in Laurel, Md., who received a $42,131 pension loan at a rate of 26.8 percent, have not received any relief.

Robert Bramson, a lawyer who represented Mr. Henry in the class-action lawsuit, said that pensioners too often failed to contemplate the long-term costs of the advances.

?It?s simply a terrible deal,? he said.

FAA clears Boeing battery fix, ending 787 flight ban

By Alwyn Scott

(Reuters) - The Federal Aviation Administration gave formal approval on Thursday for a new lithium-ion battery system for Boeing Co's 787 Dreamliner, ending a three-month ban and clearing airlines to fly the plane with passengers again.

The FAA's "airworthiness directive" technically applies just to United Airlines, which so far is the only U.S. carrier with the new high-tech jet, but it will set the standard that regulators in Japan, Europe and elsewhere will follow. Other U.S. carriers with 787s on order will eventually come under the new rule.

The FAA pegged the cost of repairing United's six jets at about $2.8 million.

The approval caps a tumultuous period for Boeing and its airline customers, beginning when two lithium-ion batteries overheated on two Dreamliners in separate incidents less than two weeks apart in January.

The two planes are owned by Japan Airlines and All Nippon Airways, which together own nearly half the fleet of 50 Dreamliners delivered so far. The ban on flights effectively halted deliveries of new planes to customers.

Boeing devoted thousands of hours to developing a fix, even before investigators determined what caused the batteries to overheat, emit smoke and, in one instance, catch fire. That investigation continues, led by the U.S. National Transportation Safety Board, which held hearings this week on the issue.

Last week, the FAA gave Boeing permission to begin installing the new battery system on planes. On Wednesday, the company said it expected to resume deliveries early next month and finish retrofitting the 50 customer planes by mid-May.

U.S. suspects Syria used chemical weapons, wants proof

By Phil Stewart and David Alexander

WASHINGTON (Reuters) - The White House said on Thursday the Syrian government of President Bashar al-Assad had probably used chemical weapons on a small scale in the country's civil war, but insisted that President Barack Obama needed definitive proof before he would take action.

The disclosure created a quandary for Obama, who has set the use of chemical weapons as a "red line" that Assad must not cross. It triggered calls from some hawkish Washington lawmakers for a U.S. military response, which the president has resisted.

In a shift from a White House assessment just days earlier, U.S. officials said the intelligence community believed with "varying degrees of confidence" that the chemical nerve agent sarin was used by Assad's forces against rebel fighters. But it noted that "the chain of custody is not clear."

While Obama has declared that the deployment of chemical weapons would be a game-changer and has threatened unspecified consequences if it happened, his administration is moving carefully - saying it is mindful of the lessons of the start of the Iraq war more than a decade ago.

Then, the George W. Bush administration used inaccurate intelligence to justify the invasion of Iraq in pursuit of nuclear, chemical and biological weapons that turned out not to exist.

"Given the stakes involved and what we have learned from our own recent experiences, intelligence assessments alone are not sufficient - only credible and corroborated facts that provide us with some degree of certainty will guide our decision-making," Miguel Rodriguez, White House director of the office of legislative affairs, said in a letter to lawmakers.

One senior U.S. defense official told reporters, "We have seen very bad movies before," where intelligence was perceived to have driven policy decisions that later, in the cold light of day, were proven wrong.

The term "varying degrees of confidence" used to describe the assessment of possible chemical weapons use in Syria usually suggests debate within the U.S. intelligence community about the conclusion, the defense official noted.

The White House said the evaluation that Syria probably used chemical weapons was based in part on "physiological" samples. But a White House official, briefing reporters on condition of anonymity, repeatedly declined to say what that evidence was. Nor is it clear who supplied it.

Chemical weapons experts say sarin, a nerve agent, can be detected in human tissue, blood, urine and hair samples, or in nearby soil or even leaves. But the chemical can dissipate within days or weeks, depending on ambient heat, wind and other factors.

Iraq is said to have used sarin 25 years ago in an attack on the Kurdish city of Halabja during the Iran-Iraq war. More recently, the agent was used in the 1994 attack by a religious cult on riders of the Tokyo subway system.

In Syria, U.S. officials said the scale of the use of sarin appeared limited. Nobody is "seeing any mass casualties" from the possible use of chemical weapons in Syria, one U.S. intelligence official noted.

The United States has resisted being dragged militarily into Syria's conflict and is providing only non-lethal aid to rebels trying to overthrow Assad. Washington is worried that weapons supplied to the rebels could end up in the hands of al Qaeda-linked fighters.

But acknowledgement of the U.S. intelligence assessment appeared to move the United States closer - at least rhetorically - to some sort of action in Syria, military or otherwise.

A White House official told reporters that "all options are on the table in terms of our response" and said the United States, which has been criticized for not doing enough to halt the bloodshed, would consult with its allies.

The official said the U.S. military was preparing for a range of "different contingencies," but declined to give specifics. Options available to Obama could include everything from air strikes to commando raids to setting up a Libya-style "no-fly" zone, either unilaterally or in cooperation with allies.

SURPRISE ANNOUNCEMENT

But Obama appeared intent on deflecting pressure for swift action by stressing the need for a comprehensive U.N. investigation on the ground in Syria - something Assad has blocked from going forward.

Syria's deputy foreign minister, Faisal Mekdad, in an interview with Reuters, dismissed Western and Israeli claims that government forces had used chemical weapons and said it was a "big lie" that Syria was preventing the U.N. probe.

Assad has clung to power despite repeated U.S. calls for him to step down. More than 70,000 people have been killed in the revolt against his family's decades-long autocratic rule. A military stalemate has set in, but Assad has still been able to rely on support from Russia and Iran.

"The reality is that as a country we can't declare red lines and then do nothing when they are crossed. Eventually we have to do something," said Ariel Ratner, a former Middle East adviser in the State Department and now a fellow at the Truman National Security Project.

The Obama administration's sudden disclosure caught many off guard. It came just two days after Defense Secretary Chuck Hagel and other U.S. officials appeared to play down an Israeli assessment that there had been repeated use of chemical weapons in Syria.

France and Britain have also concluded that evidence suggests chemical arms have been used in Syria's conflict.

"The intelligence community has been assessing information for some time on this issue and the decision to reach this conclusion was made within the past 24 hours," Hagel said.

The White House said it wanted to provide a "prompt response" to a query on Wednesday from lawmakers about whether Syria had used chemical weapons. The legislators' letter to Obama cited the assessments by Israel, France and Britain.

Republican Senator John McCain of Arizona, one of the leading advocates of deeper U.S. involvement in the Syrian conflict, said the intelligence assessment demanded a response.

"The president of the United States said that if Bashar Assad used chemical weapons, it would be a game-changer, that it would cross a red line," he said. "I think it's pretty obvious that red line has been crossed."

Democratic Senator Dianne Feinstein, head of the Senate Intelligence Committee, voiced concern that the public acknowledgement of the U.S. intelligence assessment could embolden Assad and may prompt him to calculate "he has nothing more to lose."

"Syria has the ability to kill tens of thousands with its chemical weapons. The world must come together to prevent this by unified action," she said.

In Brussels, the NATO alliance was "concerned by reports of the possible use of chemical weapons," an official said.

"As NATO has said in the past, any use of these weapons would be completely unacceptable and a clear breach of international law, and if any side uses these weapons we would expect a reaction from the international community," the official said.

Patriot missile interceptors that NATO has sent to Turkey, a member of the alliance which borders Syria, would "help ensure the protection of Turkey against any missile attack, whether the missiles carry chemical weapons or not," the official added.

(AP) ? A large fire that began with explosions aboard two fuel barges in Mobile, Ala., was rocked by a seventh explosion early Thursday and fire officials said they planned to let the fire, which has injured three, burn overnight.

Firefighters from Mobile and U.S. Coast Guard officials responded after 8:30 p.m. CDT Wednesday to a pair of explosions involving the gas barges in an area of the Mobile River east of downtown, authorities said.

As they were responding, a third explosion occurred around 9:30 p.m., Mobile Fire and Rescue spokesman Steve Huffman wrote in an email to The Associated Press. Additional explosions followed over the next few hours.

The Coast Guard said early Thursday that a one-nautical-mile safety zone had been established around one barge, which it said was "at the dock for cleaning."

Authorities said three people were transported to University of South Alabama Medical Center after suffering burn-related injuries. Huffman identified them as workers with Oil Recovery Co. The three were in critical condition early Thursday, according to hospital nursing administrator Danny Whatley.

Across the river, the Carnival Triumph, the cruise ship that became disabled in the Gulf of Mexico last February before it was towed to Mobile's port, was evacuated, said Alan Waugh, who lives at the Fort Conde Inn in downtown Mobile, across the river from the scene of the explosions. Waugh saw the blasts and said throngs of Carnival employees and others were clustered on streets leading toward the river as authorities evacuated the shipyard.

"It literally sounded like bombs going off around. The sky just lit up in orange and red," he said, "We could smell something in the air, we didn't know if it was gas or smoke." Waugh said he could feel the heat from the explosion and when he came back inside, his partner noticed he had what appeared to be black soot on his face.

U.S. Coast Guard Petty Officer Carlos Vega said the initial blast took place in a ship channel near the George C. Wallace Tunnel ? which carries traffic from Interstate 10 under the Mobile River. The river runs south past Mobile and into Mobile Bay, which in turn flows into the Gulf of Mexico.

Video from WALA-TV (http://bit.ly/15NEYJl) showed flames engulfing a large section of the barge, and a video that a bystander sent to AL.com (http://bit.ly/13vWz4G) showed the fiery explosions and billowing smoke over the river.

The cause of the explosion was not immediately clear, Huffman and Vega said.

"Once (the fire) is out and safe, a full investigation will take place," Huffman wrote.

Mobile Fire Chief Steve Dean told AL.com he was confident the fire wouldn't spread to nearby industrial properties, including the shipyard where the Carnival cruise ship is docked.

Huffman said the ship is directly across the river from the incident ? about two football fields in length.

The barges are owned by Houston-based Kirby Inland Marine, company spokesman Greg Beuerman said. He said the barges were empty and being cleaned at the Oil Recovery Co. facility when the incident began. He said the barges had been carrying a liquid called natural gasoline ? which he said is neither liquefied natural gas or natural gas. He said the company has dispatched a team to work with investigators to determine what caused the fire.

The explosion comes two months after the 900-foot-long Carnival Triumph was towed to Mobile after becoming disabled on the Gulf during a cruise by an engine room fire, leaving thousands of passengers to endure cold food, unsanitary conditions and power outages for several days. The ship is still undergoing repairs there, with many workers living on board.

Carnival didn't immediately respond to an emailed request for comment late Wednesday.

Earlier this month, the cruise ship was dislodged from its mooring by a windstorm that also caused, in a separate incident, two shipyard workers to fall into Mobile Bay. While one worker was rescued, the other's body was pulled from the water more than a week later.

Officials: Bomb suspect acknowledges role

BOSTON (AP) ? The surviving suspect in the Boston Marathon bombings acknowledged to the FBI his role in the attacks but did so before he was advised of his constitutional rights to keep quiet and seek a lawyer, officials said Wednesday.

It is unclear whether those statements before the Miranda rights warning would be admissible in a criminal trial and, if not, whether prosecutors even need them to win a conviction. Officials said physical evidence, including a 9 mm handgun and pieces of a remote-control device commonly used in toys, was recovered from the scene.

The suspect, Dzhokhar Tsarnaev, 19, told authorities that his older brother, Tamerlan Tsarnaev, 26, only recently recruited him to be part of the attack, two U.S. officials said. The CIA, however, named Tamerlan to a terrorist database 18 months ago, officials said Wednesday, an acknowledgment that will undoubtedly prompt congressional inquiry about whether investigators took warnings from Russian intelligence officials seriously enough.

The U.S. officials who spoke to The Associated Press were close to the investigation but insisted on anonymity because they were not authorized to discuss the case with reporters.

Tamerlan, whom authorities have described as the driving force behind the plot, was killed in a shootout with police. Dzhokhar is recovering in a hospital from injuries sustained during a getaway attempt.

Authorities had previously said Dzhokhar exchanged gunfire with them for more than an hour Friday night before they captured him inside a boat covered by a tarp in a suburban Boston neighborhood backyard. But two U.S. officials said Wednesday that he was unarmed when captured, raising questions about the gunfire and how he was injured.

More than 4,000 mourners at the Massachusetts Institute of Technology paid tribute to a campus police officer who authorities say was gunned down by the bombing suspects.

Among the speakers in Cambridge, just outside Boston, was Vice President Joe Biden, who condemned the bombing suspects as "two twisted, perverted, cowardly, knockoff jihadis."

Investigators have said the brothers appeared to have been radicalized through jihadist materials on the Internet and have found no evidence tying them to a terrorist group.

Dzhokhar told the FBI that they were angry about the U.S. wars in Afghanistan and Iraq and the killing of Muslims there, officials said.

How much of those conversations will end up in court is unclear. The FBI normally tells suspects they have the right to remain silent before questioning them so all their statements can be used against them.

Under pressure from Congress, however, the Department of Justice has said investigators may wait until they have gathered intelligence about other threats before reading those rights in terrorism cases. The American Civil Liberties Union has expressed concern about that.

Regardless, investigators have found pieces of remote-control equipment among the debris and were analyzing them, officials said. One official described the detonator as "close-controlled," meaning it had to be triggered within several blocks of the bombs.

An FBI affidavit said one of the brothers told a carjacking victim during their getaway attempt, "Did you hear about the Boston explosion? I did that."

Officials also recovered a 9 mm handgun believed to have been used by Tamerlan from the site of a Thursday night gunbattle that injured a Massachusetts Bay Transportation Authority officer, two U.S. officials said.

The officials told the AP that no gun was found in the boat. Boston police Commissioner Ed Davis said earlier that shots were fired from inside the boat.

Asked whether the suspect had a gun in the boat, Davis said, "I'm not going to talk about that."

Kurt Schwartz, director of the Massachusetts Emergency Management Agency, did respond to the report.

"Within half a mile of where this person was captured, a police officer was shot. And I know who shot him." Schwartz said. "And there were three bombs that went off, and I know where those bombs came from. ... To me, it does not change anything. This guy was captured alive and will survive. True or not true, it doesn't change anything for me."

Dzhokhar's public defender had no comment on the matter Wednesday. His father has called him a "true angel," and an aunt has insisted he's not guilty.

The suspects' parents, Anzor Tsarnaev and Zubeidat Tsarnaeva, plan to fly to the U.S. from Russia on Thursday, the father was quoted as telling the Russian state news agency RIA Novosti. The family has said it wants to take Tamerlan's body back to Russia.

In Russia, U.S. investigators traveled to the predominantly Muslim province of Dagestan and were in contact with the brothers' parents, hoping to gain more information.

Investigators are looking into whether Tamerlan, who spent six months in Russia's turbulent Caucasus region in 2012, was influenced by the religious extremists who have waged an insurgency against Russian forces in the area for years. The brothers have roots in Dagestan and neighboring Chechnya but had lived in the U.S. for about a decade.

A spokesman for the Office of Health and Human Services in Massachusetts confirmed a Boston Herald report Wednesday that Tamerlan, his wife and their daughter had received welfare benefits until last year, when he became ineligible based on family income.

The state also said Tsarnaev and his brother received welfare benefits as children through their parents while the family lived in Massachusetts.

At MIT, bagpipes wailed as students, faculty and staff members and throngs of law enforcement officials paid their respects to MIT police Officer Sean Collier, who was ambushed in his cruiser three days after the bombing.

The line of mourners stretched for a half-mile. They had to make their way through tight security, including metal detectors and bomb-sniffing dogs.

Boston native James Taylor sang "The Water is Wide" and led a sing-along of "Shower the People."

Biden told the Collier family that no child should die before his or her parents, but that, in time, the grief will lose some of its sting.

"The moment will come when the memory of Sean is triggered and you know it's going to be OK," Biden said. "When the first instinct is to get a smile on your lips before a tear to your eye."

The vice president also sounded a defiant note.

"The purpose of terror is to instill fear," he said. "You saw none of it here in Boston. Boston, you sent a powerful message to the world."

In another milestone in Boston's recovery, the area around the marathon finish line was reopened to the public, with fresh cement still drying on the repaired sidewalk. Delivery trucks made their way down Boylston Street under a heavy police presence, though some damaged stores were still closed.

"I don't think there's going to be a sense of normalcy for a while," Tom Champoux, who works nearby, said as he pointed to the boarded-up windows. "There are scars here that will be with us for a long time."

China sends largest fleet yet to disputed islands

China sent a fleet of patrol ships today to the sea area it disputes with Japan, following a controversial visit by Japanese officials to a war shrine. The latest moves are seen as a setback for a diplomatic resolution.

By Ralph Jennings,?Correspondent / April 23, 2013

Chinese surveillance ships sail in formation in waters claimed by Japan near disputed islands called Senkaku in Japan and Diaoyu in China in the East China Sea Tuesday.

Kyodo News/AP

Spats between Asia?s two most powerful nations, China and Japan, have grown uncomfortably routine since Tokyo nationalized a group of disputed islands in September. On Tuesday tensions reached a new and potentially worrisome high.

China sent eight surveillance vessels into Japanese territorial waters, apparently to track a flotilla of Japanese activists who had gone to look at the contested area. China?s presence ? an effort to exercise authority in the region ? is its largest since Japan nationalized the uninhabited islets, Kyodo News reported.

China?s use of ships in disputed waters isn?t expected to cause a war, but it raises the specter of a miscalculation at sea that could in turn create a new diplomatic row, set off more protests in Chinese cities, and strike another blow at Japanese business caught in the crossfire. Hopes of polite negotiations are also off the map for now.

"Only when Japan faces up to its aggressive past can it embrace the future and develop friendly relations with its Asian neighbors," Chinese foreign ministry spokeswoman Hua Chunying told a news conference on Monday.

As if the 80 pro-Tokyo activists weren?t enough to upset Beijing, that same day 168 Japanese lawmakers visited a Shinto shrine that?s reviled elsewhere in Asia for memorializing World War II heroes. Japan occupied parts of China from 1931 to 1945. Three cabinet ministers had already visited Yasukuni Shrine over the weekend, causing calculated reaction.

In protest, a high-level Chinese military official bailed on a trip this week to Japan as the foreign ministry lashed out.?

And China?s surveillance vessels probably weren?t loaded with olive branches. The Communist country has increasingly jousted?with Japan since around 2005 as it rose to become the world?s second largest economy.

?Such an intrusion [in the East China Sea] was certainly not undertaken spontaneously, but would have been planned and coordinated some time in advance for execution as soon as an opportunity presented itself,? says Scott Harold, associate political scientist with US-based think tank the RAND Corporation.

Japan controls the disputed islets, which it calls the Senkakus, despite 40 years of competing claims from China and a wave of destructive anti-Japanese street protests in Chinese cities last year. China criticizes the Shinto shrine visits because a memorial at the venue also honors 14 major war criminals.

The two sides are also disputing rights to an undersea natural gas field, while China periodically accuses Japan of not apologizing for the war of the 1940s. Japan says it has apologized.?

China and Japan, as the world?s No. 2 and No. 3 economies, also mean a lot to each other trade wise. The number of Japanese subsidiaries in China has grown eight times since the 1990s, and they sold $147 billion worth of goods to the country in the 2011 fiscal year.

Will the two keep meeting, along with South Korea, to discuss a three-way trade agreement? After momentum last month, the latest raises concern that this puts progress on ice.

?Both sides need to be more flexible,? suggests Ralph Cossa, president with US think tank Pacific Forum Center for Strategic and International Studies. ?Japan needs to acknowledge that the territory is in dispute, at least from a Chinese perspective, and the Chinese need to acknowledge that they are under Japan?s administrative control and that a military solution is unacceptable.?

Dutch diplomat sentenced to 12 years for spying

AMSTERDAM (AP) ? A Dutch court sentenced a diplomat to 12 years in prison Tuesday for delivering confidential NATO and European Union documents to Russian agents. The case, one of the worst spying affairs in the Netherlands in memory, is linked to that of a couple on trial in Germany on similar charges.

In Tuesday's ruling, a three-judge panel at The Hague District Court said Raymond Poeteray had damaged the interests of the Dutch state and its allies by passing on sensitive military and political documents.

"The court considers it proven that he passed on confidential documents to the Russian Federation for years and on assignment from the Russian foreign intelligence service," presiding judge A.J. Milius said, reading a written summary of the panel's ruling.

He said Poeteray gave the Russians information about the civil war in Libya, EU fact-finding missions in Georgia, and Dutch peacekeeping missions in Kosovo and Afghanistan, causing "substantial" damage.

"In addition, (Poeteray) did not shy away from giving away confidential and very private personal information about seven colleagues," potentially making them vulnerable to blackmail, the judge said.

Poeteray, 61, was working at the Netherlands' Foreign Affairs Ministry after serving in the Dutch embassies in Hong Kong and Indonesia earlier in his diplomatic career, which began in 1978. He was arrested in March 2012 in connection with a German investigation.

In Germany, a couple that called themselves Andreas and Heidrun Anschlag ? true identies unknown ? were arrested in October 2011. They are on trial for allegedly compiling the information that Poeteray gathered and sending it on to Russia's intelligence agency.

The Hague court found Poeteray "acted purely in pursuit of profit, to pay off his debts and to be able to allow himself a certain lifestyle."

He was paid at least ?72,000 ($94,000) in cash alone between January 2009 and August 2011, the ruling said.

Poeteray's lawyers had argued he was innocent. He explained the large amounts of cash in his bank accounts by saying he had been able to purchase jewelry cheaply while serving overseas and had been selling it off.

Judges rejected that as not credible, given that he was deeply in debt. They also noted that instructions Poeteray had received via the Anschlags had told him to use that explanation.

Defense and prosecution lawyers have two weeks to consider whether they will appeal. Prosecutors had asked for a 15-year sentence.

The court granted one request by Poeteray: it ordered the return of five of his watches seized during the investigation, branded as an Omega, a Graham, a Breitling, a Bulgari, and a Corum. All were fakes.

Residential lawns efflux more carbon dioxide than corn fields, study finds

Apr. 23, 2013 ? More carbon dioxide is released from residential lawns than corn fields according to a new study. And much of the difference can likely be attributed to soil temperature. The data, from researchers at Elizabethtown College, suggest that urban heat islands may be working at smaller scales than previously thought.

These findings provide a better understanding of the changes that occur when agricultural lands undergo development and urbanization to support growing urban populations.

David Bowne, assistant professor of biology, led the study to look at the amount of carbon dioxide being released from residential lawns versus corn fields in Lancaster County, Pennsylvania. His co-author, Erin Johnson, was an undergraduate at the time of the study and did the work as part of her senior honors thesis. Their findings were published online today in Soil Science Society of America Journal.

For Bowne, the study allowed him to look beyond the obvious impact of losing agricultural fields to development -- the loss of food that was once produced on the land.

"That is a legitimate concern, but I wanted to look more at how this change could potentially impact the carbon cycle with the understanding that the carbon cycle has implications for global climate change," explains Bowne.

To begin to understand how the carbon cycle was changing, Bowne and Johnson measured carbon dioxide efflux, soil temperature, and soil moisture under the two different land uses. They found that both carbon dioxide efflux and soil temperature were higher in residential lawns than in corn fields. Additionally, temperature had the most influence on the levels of carbon dioxide efflux, followed by the type of land use.

Higher temperatures leading to increased carbon dioxide efflux was not a surprise for Bowne and Johnson as this relationship has been documented before. "As you increase temperature," Bowne explains, "you increase biological activity -- be it microbial, plant, fungal, or animal." That increased activity, then, leads to more respiration and higher levels of carbon dioxide leaving the soils.

What was unexpected, however, was that the higher temperatures found in residential lawns suggested urban heat islands working at small scales. Urban heat islands are well documented phenomena in which development leads to large areas of dark-colored surfaces such as roofs, buildings, and parking lots. The dark color means more heat is absorbed leading to an increase in temperature in the neighboring areas. Urban areas, then, are warmer than the surrounding countryside.

The interesting part of Bowne's study is that the urban heat islands in the areas he was looking seem to operate on much smaller scales than he previously thought. While heat islands are usually studied on large scales -- such as comparing a large city and its surrounding rural areas -- fewer studies have been done to work out how development may affect temperatures on small scales.

"Within a developed area, within a city or town, you could have local increases in soil temperature because of the amount of development within a really small area," says Bowne.

His research suggests that temperatures may vary even across short distances due to the influence of development. One source cited in his paper says that development within even 175 meters of a location can cause an increase in temperature. Bowne is planning further experiments to test soil temperatures over a range of development setups and sizes.

The other factor that Bowne will test in the future is the sequestration of carbon. Along with the carbon dioxide efflux data in the current study, information about carbon sequestration would give a bigger picture of carbon cycling. That picture could then help researchers determine how various land uses as well as management practices such as no-till agriculture or leaving grass clippings on lawns can change the carbon cycling.

"If we go from one land use to another land use, how does that impact carbon cycling which in turn can affect climate change? Our current study touches on one component of that cycle, and more research is needed to address this huge topic," says Bowne.

Iron in primeval seas rusted by bacteria

Apr. 23, 2013 ? Researchers from the University of T?bingen have been able to show for the first time how microorganisms contributed to the formation of the world's biggest iron ore deposits. The biggest known deposits -- in South Africa and Australia -- are geological formations billions of years old. They are mainly composed of iron oxides -- minerals we know from the rusting process. These iron ores not only make up most of the world demand for iron -- the formations also help us to better understand the evolution of the atmosphere and climate, and provide important information on the activity of microorganisms in the early history of life on Earth.

The extent to which microbes in the Earth's ancient oceans contributed to the formation of iron deposits was previously unknown. Now an international team of researchers from the US, Canada and Germany has published new findings in the journal Nature Communications. Led by University of T?bingen geomicrobiologist Professor Andreas Kappler of the Center for Applied Geoscience, they found evidence of which microbes contributed to the formation of the iron ores, and were able to show how different metabolic processes can be distinguished in the rock formations today.

The iron in the Earth's ancient oceans was spat out of hot springs on the seafloor as dissolved, reduced ferrous [Fe(II)] iron. But most of today's iron ore is oxidized, ferric [Fe(III)] iron in the form of "rust minerals" -- indicating that the Fe(II) was oxidized as it was deposited. The classic model for the formation of iron deposits suggested that the Fe(II) from the Earth's core was oxidized by the oxygen produced by cyanobacteria (blue-green algae). This process can happen either chemically (as in the formation of rust) or by the action of microaerophilic iron-oxidizing bacteria.

But scientists are still debating at what point the Earth's atmosphere contained enough oxygen (produced by cyanobacteria) to allow the formation of big iron deposits. The oldest known iron ores were deposited in the Precambrian period and are up to four billion years old (the Earth itself is estimated to be about 4.6 billion years old). At this very early stage in geological history, there was little or no oxygen in the atmosphere. So the very oldest banded iron formations cannot be the result of O2-dependent oxidation.

In 1993, bacteria were discovered which do not need oxygen but can oxidize Fe(II) by using energy from light (anoxygenic phototrophic iron-oxidizing bacteria). Studies by Professor Kappler's team in 2005 and 2010 showed that these bacteria transform dissolved ferric iron into iron oxide (rust) -- like the material in the early iron ores. Now, the geomicrobiologists from T?bingen have been able to demonstrate that, by examining the identity and structural properties of the iron minerals, it is possible to tell that the minerals were deposited by iron-oxidizing microbes and not by oxygen made available by the action of cyanobacteria. To do this, the researchers placed different amounts of organic material together with iron minerals into gold capsules and increased the pressure and temperature to simulate the transformation of the minerals over geological time. They ended up with structures of iron carbonate minerals (siderite, FeCO3), just as they occur in geological iron formations. In particular, they were able to distinguish iron carbonate structures which had been formed in the presence of a rather small amount of organic compounds (microbial biomass) from those formed in the presence of a larger amount.

This research not only provides the first clear evidence that microorganisms were directly involved in the deposition of Earth's oldest iron formations; it also indicates that large populations of oxygen-producing cyanobacteria were at work in the shallow areas of the ancient oceans, while deeper water still reached by the light (the photic zone) tended to be populated by anoxyenic or micro-aerophilic iron-oxidizing bacteria which formed the iron deposits.
