BBC plans 'Tweet of the Day,' radio for birds
LONDON (AP) ? Remember when tweeting was for the birds?
The BBC is hoping to revive that simpler time with "Tweet of the Day" ? an early-morning radio program dedicated to British birdsong.
Veteran naturalist David Attenborough will host the 90-second show, which will feature the song of a different bird each weekday, along with background on the species' behavior and habits.
The show on the BBC's main speech station, Radio 4, may be best appreciated by those who rise with the birds. "Tweet of the Day" will be broadcast at 5:58 a.m.
The BBC said Wednesday that 265 different birds will be featured during the year-long series, which begins next month with a recording of the cuckoo. Attenborough will host for the first month, and be followed by other BBC presenters.

Pakistan police say explosives found near Musharraf house
By Mehreen Zahra-Malik
ISLAMABAD (Reuters) - Pakistani police said on Tuesday they had defused 50 kg (110 lb) of explosives hidden in a car wired with remote-controlled detonators near the fortified farmhouse where former president Pervez Musharraf is under house arrest.
The discovery added a new sub-plot to the saga of Musharraf's deepening legal woes, which have transfixed Pakistanis unaccustomed to the sight of a once all-powerful military ruler submitting to the will of judges.
"When we checked the car we found explosives," police bomb squad constable Rehmat Ali told Reuters television. "When we unlocked one of the doors we saw a detonator cord."
Ali added that police had discovered several remote-controlled detonators rigged to the explosives, which they disarmed.
There was no immediate word from police on who they suspected might have planted the device.
Pakistan's Taliban movement, which threatened to kill Musharraf shortly before he returned to Pakistan last month after almost four years of self-imposed exile, denied any involvement in the incident.
"We would have sent suicide bombers," Taliban spokesman Ehsanullah Ehsan said.
MADE ENEMIES
Musharraf made many enemies during his stint in power, notably among militant groups who felt betrayed by his decision to align Pakistan with the United States following the September 11, 2001 attacks.
Musharraf had hoped to relaunch his political career by running for a seat in the National Assembly at general elections on May 11, Pakistan's first transition between elected civilian-led governments.
Instead, election officials disqualified him from running and a court ordered he be placed under house arrest last week over allegations he unlawfully ordered the detention of judges during a showdown with the judiciary in 2007.
Police found the explosives several hours after Musharraf made his latest court appearance over separate allegations that he failed to provide adequate security to prevent the 2007 assassination of former prime minister Benazir Bhutto.
Pakistani television broadcast video showing scores of lawyers, who have not forgiven Musharraf for the crackdown he launched on the judiciary, scuffling with supporters of the ex-president after the hearing.
Police arrested Musharraf on Friday, treating Pakistanis to the rare spectacle of a former army commander being humbled by judges in a country where the military has ruled for more than half the years since Pakistan's creation in 1947.
Musharraf's office has dismissed the allegations against him as baseless and politically motivated.
Musharraf, who seized power in a coup in 1999, resigned in 2008 and left Pakistan for residences in London and Dubai.
His legal troubles have provided a stark symbol of the changing balance of power in Pakistan, where the military still retains enormous behind-the-scenes influence but has retreated from the overt meddling and coups of the past.

Sprint delays Galaxy S 4 in-store launch due to inventory issues, online and phone sales aren't affected
After T-Mobile said yesterday that it won't be able to offer Samsung's Galaxy S 4 through its online store quite as soon as it expected, Sprint has today announced a similar delay. The carrier originally planned to have Sammy's latest flagship available through all retail channels this Saturday (April 27th), but "unexpected inventory challenges from Samsung" have meant that although online and phone-based sales will open on that date as planned, you won't be able to wander into a Sprint store and pick one up until those supply issues are solved. When that'll be is anyone's guess, but we imagine Sprint will get them into consumers' hands as soon as possible in the hope of improving its balance sheet. See Sprint's full statement after the break.

McGraw-Hill seeking dismissal of lawsuit over S&P
LOS ANGELES (AP) -- The parent company of Standard & Poor's wants a federal judge to dismiss a U.S. government lawsuit that claims the ratings agency gave falsely high ratings to mortgage investments that helped trigger the financial crisis.
Attorneys for McGraw-Hill Cos. Inc. delivered their arguments in documents filed Monday in U.S. District Court in California.
The motion asserts that the government's complaint against S&P is "a stretch," noting that other agencies issued ratings identical to S&P.
It also argues that the ratings firm's inability to predict the extent of the financial meltdown was a lack of prescience ? not fraud. It notes the crisis was something that the Federal Reserve, U.S. Treasury and Wall Street also failed to see coming.
The government filed the civil lawsuit against New York-based McGraw-Hill in February and aims to seek billions in damages.
The Justice Department claims S&P knowingly inflated its ratings because it wanted to earn more business from its lender clients whose investments it was hired to rate.
According to the lawsuit, S&P recognized in 2006 that home prices were sinking and that borrowers were having trouble repaying loans. Yet these facts weren't reflected in the safe ratings S&P gave to complex real-estate investments known as mortgage-backed securities and collateralized debt obligations, or CDOs, the lawsuit alleges.
High ratings from S&P and the two other main credit rating agencies ? Fitch and Moody's ? made it possible for banks to sell trillions in risky investments. Some investors, including pension funds, can buy only securities that carry high credit ratings.
But in its filing Monday, McGraw-Hill argues that U.S. District Court Judge David O. Carter should dismiss the case because the government failed to show S&P intended to defraud investors in CDOs.
In one example, the company contends that two of S&P's "supposed victims," Citibank and Bank of America, were creating and selling the CDOs that the S&P was rating.
"In other words, the complaint charges S&P with intending to defraud these financial institutions about the likely performance of their own products," the filing said.
McGraw-Hill also makes the point that it could not have been fraudulent for S&P to continue to rely on its ratings for residential mortgage-backed securities if the firm continued to update its ratings "in good faith."
The claim against S&P is the Obama administration's most aggressive action to date against those deemed responsible for contributing to the worst financial crisis since the Great Depression. Its follows years of criticism that the government had failed to do enough.
Shares of McGraw-Hill ended regular trading up 15 cents at $52. The stock is down about 5 percent this year.

Afghanistan says negotiating release of helicopter hostages
KABUL (Reuters) - The Taliban may free a group of mainly Turkish hostages captured when their helicopter made an emergency landing in a Taliban-controlled area of eastern Afghanistan as early as Tuesday night, a provincial official said.
Negotiations between village leaders and the Taliban were underway, and that was leading to hopes they could be freed within hours, a spokesman for the governor of Logar province told Reuters.
"Tribal elders are playing an important role in this incident - they have already talked with the Taliban and we hope the hostages could be freed this evening," Din Mohammad Darwish said.
The eight Turkish engineers, an Afghan and two pilots from Russia and Kyrgyzstan were onboard a Russian Mi-8 helicopter when it made a "hard landing" in a remote part of Logar province due to bad weather on Sunday afternoon.
They were taken captive by the insurgency, which controls the area, according to officials and a Taliban spokesman.
A group of police were sent to Azra district to investigate on Monday but were fired upon by unknown men and had to leave, Rais Khan Sadiq, the deputy head of Logar police, said, adding that there is no NATO or Afghan army presence in the district.
Since being captured the eleven had been moved from Logar's conflict-riven Azra district to Hesarak district in neighboring Nangarhar province, Sadiq said.
No operation to rescue the hostages was being planned while the village elders negotiated with the Taliban, Sadiq said.
"We want to solve this problem with mediation of local elders. If we don't reach any conclusion then we will plan a military operation," he said.
He also denied a Taliban statement that the helicopter had been set fire by the insurgents, saying it had been seen by police and it was still intact.
The engineers from a Turkish construction company were returning to Kabul from the eastern border province of Khost, when the helicopter, owned by air charter company Khorasan Cargo Airlines, was forced to land.
Both the Russian and Turkish foreign ministries have confirmed they had citizens aboard the helicopter.
Helicopter crashes and "hard landings" happen relatively frequently in mountainous Afghanistan.
In August 2011, 30 U.S. special forces soldiers, seven Afghans and an interpreter were killed when a Chinook transport helicopter was shot down, the deadliest single incident for foreign troops in more than a decade of war.
Khorasan flies Russian Mi-8 and Mi-17 helicopters as well as fixed-wing aircraft in Afghanistan. They offer troops and cargo transportation as well as medivac and civilian transportation services.

Masdar Institute becomes affiliate of Joint Institute for Strategic ...
Initially, Masdar and JISEA will collaborate in three areas: water-energy nexus, clean energy policy with focus on the Middle East/North Africa region, and energy access in developing countries. The agreement also offers options for expanding the scope of collaboration at a later stage.
A trans-disciplinary global research group focused on the nexus of energy, environment, finance, and society, JISEA is headquartered at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL). With five founding institutions rooted in research, JISEA provides capabilities in research and analysis that far outweigh those of a single organization.
"I am very excited about JISEA's affiliation with Masdar Institute," said Douglas Arent, JISEA executive director. "Masdar Institute offers excellent research capabilities and unique regional insights that complement the skills and knowledge of JISEA partners and allow us to offer increased value to our clients interested in energy access and sustainability, particularly in the Middle East/North Africa region."
Dr Fred Moavenzadeh said, "The affiliation agreement with the Joint Institute for Strategic Energy Analysis will broaden our reach in international collaboration that will naturally further our capabilities in sustainable research projects. JISEA engages in leading-edge, objective, high-impact research and analysis to guide global energy investment and policy decisions. Its focus on the nexus of energy, finance, and society, are similar to the issues being addressed by us. With the guidance of the UAE's leadership, we will continue to seek partnerships with global organizations to further our research in clean energy and sustainability."
Research forms the core area for Masdar Institute which focuses on three themes for scientific innovation - water, energy and environment; energy systems; and advanced materials. The research-based institution ion Abu Dhabi continues to excel in research success. For 2012, total publications by Masdar Institute so far include papers in 311 peer reviewed journals, 330 conference proceedings, two full books and 37 invention disclosures. One patent is already issued, while 20 active patent applications are pending.
Serving as a key pillar of innovation and human capital, Masdar Institute remains fundamental to Masdar's core objectives of developing Abu Dhabi's knowledge economy and finding solutions to humanity's toughest challenges such as climate change.
Established as an on-going collaboration with the Massachusetts Institute of Technology (MIT), Masdar Institute integrates theory and practice to incubate a culture of innovation and entrepreneurship, working to develop the critical thinkers and leaders of tomorrow. With its world-class faculty and top-tier students, the Institute is committed to finding solutions to the challenges of clean energy and climate change through education and research.
JISEA is operated by the Alliance for Sustainable Energy, LLC, on behalf of its founding partners. They include the U.S. Department of Energy's National Renewable Energy Laboratory, University of Colorado-Boulder, Colorado School of Mines, Colorado State University, Massachusetts Institute of Technology, and Stanford University.

Slovenia insists it's not the next Cyprus
LJUBLJANA, Slovenia (AP) ? Slovenian officials have a message for the world: Don't panic ? we won't be the next to fall.
The tiny European Union member is trying to convince its people and foreign investors that it won't be the next in line for a banking system collapse and a messy international bailout.
"We are absolutely no Cyprus," says new Slovenian Prime Minister Alenka Bratusek. "We don't need help. All we need is time."
But time is running out for the Balkan state, once considered an East European success story and a model for the rest of the region on how to build a post-communist economy. With few specifics from leaders on a rescue plan, some economists are skeptical they can live up to their promises.
Slovenia desperately needs fundamental reform of its banking and economic system if it is to avoid the same fate as Cyprus, a fellow member of the 17-strong group of European Union countries that use the euro. The island nation was forced to ask for a bailout from its fellow eurozone countries, the European Central Bank and the International Monetary Fund when it could not afford to support its bloated banking sector.
Now the fear is Slovenia could face the same fate. While its overall public debt load is well below the EU average, the country of 2 million is facing difficulties refinancing its debt. That has fueled fears that Slovenia ? which accounts for 0.4 percent of the eurozone's overall economy ? could become the sixth eurozone nation to require assistance.
At the core of Slovenia's problems are its state-run banks, which control about 60 percent of the country's banking sector.
The Alpine country's banks have been on a lending spree for years, loaning money to unprofitable state companies or privileged officials who used the cash to buy the firms they ran, using the state assets as collateral.
Many such businesses have now collapsed or have huge debts. A recent report by the Organization for Economic Cooperation says that the equity of the state banks has been "virtually wiped out." As much as 15 percent of all loans are now non-performing, the third-highest ratio in the eurozone, the Paris-based group said.
"In Slovenia, tycoons have stolen everything," Mico Pavic, a retired construction worker said at Ljubljana's main Presern square, where a Gypsy folk band created a relaxed atmosphere at odds with the country's situation. "I have been here since 1960, and I have not seen a bigger crisis."
Bank officials say that despite fears of a financial sector collapse, there has been no rush on banks to pull out cash from private saving accounts. That is primarily because Slovenes ? despite a recent spate of anti-government protests ? traditionally trust their state, which has provided them in the past with good welfare and standards of living.
"We are not some kind of a tax haven for global billionaires, nor does our banking sector constitute the bulk of our GDP," Bratusek said in an opinion piece in the Wall Street Journal, apparently referring to Cyprus where the bulk of saving accounts belonged to wealthy Russians. "Not all is rosy in Slovenia, but that is true for all of Europe."
Cyprus agreed last month that in return for a 10 billion euro bailout loan it would contribute a further 13 billion euros ? mainly by breaking up one of its banks and forcing haircuts of up to 80 cents on the dollar for anyone with more than 100,000 euros in a deposit account.
Janko Medja, the head of Nova Ljubljanska Banka, Slovenia's largest troubled state-run bank, said Slovenia will avoid a similar deal because of the comparative size of their banking sectors.
Slovenia's banking sector is worth about 130 percent of the country's GDP of about 36 billion euros. The sector in Cyprus, by contrast, had swollen to eight times the nation's annual economic output.
The core of the Slovenia's problems is the failure to privatize the economy, including the state banks, Medja said.
"It is safe to say that the problem for this house, with NLB having a 30 percent market share in Slovenia, accumulated over the past 10 years, and we are having a very tough job of restructuring it," Medja, who took over late last year to try stabilize the bank, said in an interview.
"It will take a couple of years to get to a rebound situation," he said, adding that the bank will initially need some 400 million euros ($524 million) for immediate recapitalization. Economists estimate that NLB needs some 2.5 billion euros ($3.2 billion) for a complete bailout.
"We in the NLB are proceeding as if there will be no need for a bailout," Medja said.
But the Slovenian banks' troubles are large enough for investors to fear the government might face huge costs rescuing them. That has pushed up the government's borrowing rates in bond markets to near the levels Cyprus faced on the eve of seeking the bailout.
"Recent events have underlined our view that the Slovenian government will struggle to finance itself this year despite the small size (relative to GDP) of its troubled banks and public debt," Capital Economics Ltd., a London-based analyst group, said. "To avoid a bailout, the government will need rapidly to put in place a credible plan to tackle the banking crisis."
The government is setting up a so-called bad bank to retake shaky loans and investments off banks' hands and is working "literally day and night" on fixing the financial sector, Bratusek said.
"The first priority of our government is the stabilization of our banking system," said Bratusek, whose center-left government took over two months ago after the fall of previous center-right Prime Minister Janez Jansa over corruption allegations. "But that alone won't help our economy, as we also have to also stabilize our over-indebted companies."
Slovenian economic analysts are unimpressed by the new government actions taken so far.
"It is still possible that Slovenia will escape the bailout, but it depends on government measures," analyst Joze P. Damjan said. "The problem is that we still don't know what those measures are."

BASEBALL Roundup for Wednesday April 17
All Baseball Stories Step aside, Ronald McDonald and the golden arches. It was the Big Zack attack Wednesday afternoon.
Stevenson?s Zack McGuire not only pitched marvelously during the final 2 2/3 innings to earn a save, he also swatted a grand slam as the Titans defeated L?Anse Creuse North 10-2 in a MAC Red Division game.
When McGuire came in to pitch in the fifth, bases were loaded and his team led 5-2. He proceeded to strike out two consecutive batters to thwart the threat and did not allow a run the rest of the game.
His slam in the sixth put his team up by the final margin, 10-2.
McGuire was not alone in his hitting heroics. Junior outfielder Brandon Hughes continued his absolute tear. He had three more hits including a leadoff home run on the first pitch of the game. Hughes has 11 hits in his last 14 at-bats. Teammate Zak Melcher, a senior outfielder, ripped two doubles and added a single. Sophomore shortstop Riley McCauley ripped a two-run single in the third inning to put the Titans ahead 4-1. He also had a sacrifice fly later in the game.
Winning pitcher Joe Wolf threw 4 1/3 innings.
?I expected us to be solid this year, but we are swinging the bats a lot better than we did last year,? said Joe Emanuele, the Stevenson coach.
Stevenson is 2-0 in division play, 5-0 overall.
MAC RED DIVISION
DAKOTA 14, GROSSE POINTE SOUTH 4: From the Department of Redundancy Department; the Cougars won again.
Winning pitcher Travis Perkola went all six innings, striking out six, as Dakota raised its record to 2-0 in the division, 9-0 overall.
Daniel Herman and Frank Maloney each had three hits and three RBI for Dakota.
MAC WHITE DIVISION
ROMEO 3, FORD 1: Let?s chalk this one up to dogged determination as the unbeaten Romeo Bulldogs bumped their record to 2-0 in the division, 5-0 overall.
Winning pitcher Greg Antoine threw the first five innings. He gave up two hits and fanned four. He also had a hit and knocked in a run. The save went to Eric Shankin, who went the final two innings, allowing two hits but striking out six.
Senior catcher Joey Gardner had two hits and an RBI. Senior outfielder Derek Staelgrave had a hit and an RBI. Ryan Price, a senior third baseman, swatted a hit and scored twice.
Romeo welcomes De La Salle Friday.
WARREN-MOTT 4, L?ANSE CREUSE 3: Over six innings, Joey Slivik tossed a complete game, striking out four and giving up four hits and one earned run. On offense, he had two doubles, drove in a run and scored two runs.
Nick Maluchnik went 2-for-3 and had two hits and Pierson Heythaler was 1-for-1 with a walk and an RBI.
In the last inning, second baseman Geoffrey Morrow threw out the tying run at the plate and made a long catch on a foul ball in right field to end the game.
For L?Anse Creuse, Bryton Rohdie went 2-for-2 with a walk and an RBI.
Warren-Mott takes on Chippewa Valley on Thursday.
MAC BLUE DIVISION
ANCHOR BAY 6, PORT HURON NORTHERN 5: Gary Landles got the win on the mound, he also had three hits and two RBI.
Connor Kost and Austin Tosto each had two hits, and Craig Black drove in the game-winning run in the bottom of the seventh inning.
Anchor Bay is 4-3 overall and 2-0 in the division.
CATHOLIC LEAGUE CENTRAL DIVISION
DE LA SALLE 11, DIVINE CHILD 4: Pitchers Brent Morris and Hosea Nelson combined to toss a three-hitter as the Pilots evened their record at 5-5.
Morris started the game and went the first 3 2/3 innings before being sidelined by a 90-minute rain delay. Nelson closed out the game.
Nelson also had two rips at the plate including a triple and four RBI. Senior outfielder Cole Clifton had three hits including a double and two RBI. Junior second baseman Dominic DiPuma went 3-for-4 and knocked in two runs. Sam Badalamenti, a junior centerfielder, went 3-for-5.

Ga. college students to pay higher tuition
SAVANNAH, Ga. (AP) -- Public colleges and universities in Georgia will charge students $32 to $270 more in tuition per semester starting next fall under a budget plan approved Tuesday by the state Board of Regents.
College students and their parents have seen the cost of their educations go up every year for more than a decade. The tuition hikes approved by the regents for Georgia's 31 public schools were held at the same rate as the increases adopted a year ago, which were the lowest since 2002.
For 27 schools in the University System of Georgia, students will pay 2.5 percent more. That translates to an extra $32 to $83 per semester at campuses ranging from Georgia Southern University to Dalton State University to Armstrong Atlantic State University, where the regents held their Tuesday meeting in Savannah.
The remaining four schools, Georgia's larger research universities, will raise their rates even more. Georgia Tech students will take the hardest hit, with in-state undergraduates paying an extra $270 ? or 7 percent ? each semester. University of Georgia undergrads will pay $191 more per semester, a 5 percent increase. Georgia State University in Atlanta and Georgia Regents University in Augusta will both raise undergraduate tuition 3.5 percent, about $131 per semester.
The regents approved the tuition increases despite getting an additional $54.6 million in funding from the Legislature for the next school year. Chancellor Mike Huckabee said the University System is still struggling to keep up with soaring enrollment, higher health care premiums for employees and other costs after absorbing $1.4 billion in budget cuts in the past five years.
"We worked very hard to keep it at affordable levels," Huckabee said. "But we're nowhere close to where we were being funded five years ago."
University system officials say the average tuition cost in Georgia remains below those in neighboring Southern states such as Tennessee, Alabama and South Carolina.
Still, members of the Board of Regents said they're aware that Georgia families are being asked to pay for college at a time when many are still hurting from the recession. Dink NeSmith, the board's chairman, said the regents soon want to see a year without a rise in tuition ? perhaps for the school year starting in fall 2014.
"It'll probably take us another year, but we'd like to have no increase in tuition," said NeSmith, though he said it's too early to say how that would be accomplished. "We think it's possible."
In addition to raising tuition, the regents approved mandatory fee increases at 16 schools ranging from an additional $6 health fee for Georgia Tech students to $53 in new recreation and athletic fees for Dalton State College students.
Chanel Riggins, a freshman nursing student at Armstrong Atlantic State University in Savannah, said even small cost increases can hurt. Next fall, her tuition will go up $56 per semester to $2,312, and she'll be charged an extra $27 in mandatory health and student center fees.
"It means a lot," said Riggins, who's using student loans and money her father has borrowed to pay for school. "My father's in the military, and he's got five kids. This just puts him further into debt, and he's already complaining about the bills."

Russian anti-Putin protest leader expects to be jailed
By Timothy Heritage and Kiryl Sukhotski
MOSCOW (Reuters) - Russian protest leader Alexei Navalny accused Vladimir Putin on Monday of orchestrating a trial against him on theft charges, and said he was sure he would be found guilty in a campaign to crush the opposition.
The 36-year-old anti-corruption blogger, who emerged as the president's most powerful opponent during protests that began in December 2011, goes on trial in the city of Kirov on Wednesday on what he says are trumped-up charges.
Putin's opponents have compared the trial with that of Mikhail Khodorkovsky, a former oil tycoon convicted in 2005 of fraud and tax evasion in a move which critics say was intended by the president to discourage others from taking him on.
Navalny dismissed the accusations against him as "absurd" but said his fate had already been determined. "I'm absolutely sure it will end in a guilty verdict," he said in an interview at his cramped and sparsely furnished Moscow office, from where he campaigns against corruption among state firms and officials.
"They've already decided everything, including the sentence. They're interested in some kind of public relations, to say on television that the man who for years has been accusing us of corruption is corrupt himself. By them, I mean Putin."
As if to underline his point, he sat at a desk in front of a laptop with a sticker on it showing Putin's face in the letter O of "vor", the Russian word for thief.
Putin's spokesman Dmitry Peskov declined comment. However, he has denied the president exploited weaknesses in the justice system to stifle opposition since he returned to the Kremlin last May after four years as premier.
Navalny faces up to 10 years in prison if found guilty of leading an organised group accused of stealing 16 million roubles ($512,000) from a timber firm which he was advising while working for the Kirov regional governor in 2009.
He believes it is now merely a question of whether he goes to jail or receives a suspended sentence in the trial in Kirov, about 900 km (600 miles) northeast of Moscow.
THE RISKS OF OPPOSITION POLITICS
Despite the threat of jail, Navalny appeared calm, often smiling wryly and showing little emotion. He seemed resigned to going to jail, describing it as a risk he had known about when he started criticizing the authorities in his blogs.
"If you get into opposition politics, they can put you in jail. If you take on corruption, the easiest thing for these people is to put you in jail," he said.
Navalny said the allegations against him were part of a Kremlin strategy to intimidate critics and stifle protests.
"Putin and his inner circle have realised that they have no levers left at their disposal to keep control of the political system except repression," he said.
"They see the decline in (Putin's) ratings and the growing discontent, and the protests continue ... They will crush anyone who objects to Putin being president for life."
A trained lawyer, Navalny has campaigned since 2007 against corruption by state officials and firms but it was the protests that began 16 months ago over alleged fraud in a parliamentary election which confirmed him as an opposition leader.
He was jailed for 15 days for his role in one of the first demonstrations in December 2011 and emerged as the most dynamic speaker at rallies which developed into the biggest protests since the former KGB spy came to power 13 years ago.
Clean cut and articulate, Navalny harnessed a mood change among urban youth against Putin's political domination. His description of the ruling party as "swindlers and thieves" struck a chord with Russians from the Pacific Ocean to the Baltic Sea.
He is a particular threat for Putin because of his powers as a public speaker and his large following online, although it is not clear how much support he has outside the big cities and the anti-Putin protests have dwindled since their height.
DANGER FOR PUTIN?
The trial is one of the most high-profile cases against a Putin opponent since he was first elected president in 2000 and set about restoring order after the chaos that followed the collapse of the Soviet Union in 1991 and Boris Yeltsin's rule.
The danger for Putin is that Navalny's popularity and fame could increase if he is jailed, as happened with Khodorkovsky.
"The more Navalny is tormented (by the Kremlin), the greater the number of people ready to give him their support. And the more Navalny is tormented, the more he is seen as an opposition leader," said political analyst Yulia Latynina.
Efforts by state-backed media to portray him as an extremist with nationalist tendencies - which he denies despite some anti-immigration rhetoric at the start of his political career - have failed to dent his appeal among Russia's emerging middle class.
He says that regardless of his own fate, the state of Russia's economy, heavily dependent on energy exports, has declined to such an extent that Putin can no longer rely on economic handouts such as pay rises to keep a lid on discontent.
"The effect of petrodollars has stopped working in terms of political stability. The propaganda machine that has been used so actively over the last few years has reached a peak. Internet penetration is increasing and in this sense, time and technology are working in our favor," he said.

Ordinary skin cells morphed into functional brain cells
Apr. 14, 2013 ? Researchers at Case Western Reserve School of Medicine have discovered a technique that directly converts skin cells to the type of brain cells destroyed in patients with multiple sclerosis, cerebral palsy and other so-called myelin disorders.
This discovery appears today in the journal Nature Biotechnology.
This breakthrough now enables "on demand" production of myelinating cells, which provide a vital sheath of insulation that protects neurons and enables the delivery of brain impulses to the rest of the body. In patients with multiple sclerosis (MS), cerebral palsy (CP), and rare genetic disorders called leukodystrophies, myelinating cells are destroyed and cannot be replaced.
The new technique involves directly converting fibroblasts -- an abundant structural cell present in the skin and most organs -- into oligodendrocytes, the type of cell responsible for myelinating the neurons of the brain.
"Its 'cellular alchemy,'" explained Paul Tesar, PhD, assistant professor of genetics and genome sciences at Case Western Reserve School of Medicine and senior author of the study. "We are taking a readily accessible and abundant cell and completely switching its identity to become a highly valuable cell for therapy."
In a process termed "cellular reprogramming," researchers manipulated the levels of three naturally occurring proteins to induce fibroblast cells to become precursors to oligodendrocytes (called oligodendrocyte progenitor cells, or OPCs).
Tesar's team, led by Case Western Reserve researchers and co-first authors Fadi Najm and Angela Lager, rapidly generated billions of these induced OPCs (called iOPCs). Even more important, they showed that iOPCs could regenerate new myelin coatings around nerves after being transplanted to mice -- a result that offers hope the technique might be used to treat human myelin disorders.
When oligodendrocytes are damaged or become dysfunctional in myelinating diseases, the insulating myelin coating that normally coats nerves is lost. A cure requires the myelin coating to be regenerated by replacement oligodendrocytes.
Until now, OPCs and oligodendrocytes could only be obtained from fetal tissue or pluripotent stem cells. These techniques have been valuable, but with limitations. "The myelin repair field has been hampered by an inability to rapidly generate safe and effective sources of functional oligodendrocytes," explained co-author and myelin expert Robert Miller, PhD, professor of neurosciences at the Case Western Reserve School of Medicine and the university's vice president for research. "The new technique may overcome all of these issues by providing a rapid and streamlined way to directly generate functional myelin producing cells."
This initial study used mouse cells. The critical next step is to demonstrate feasibility and safety using human cells in a lab setting. If successful, the technique could have widespread therapeutic application to human myelin disorders. "The progression of stem cell biology is providing opportunities for clinical translation that a decade ago would not have been possible," said Stanton Gerson, MD, professor of Medicine-Hematology/Oncology at the School of Medicine and director of the National Center for Regenerative Medicine and the UH Case Medical Center Seidman Cancer Center. "It is a real breakthrough."
Additional co-authors of the publication include Case Western Reserve School of Medicine researchers Anita Zaremba, Krysta Wyatt, Andrew Caprariello, Daniel Factor, Robert Karl, and Tadao Maeda.
The research was supported by funding from the National Institutes of Health, the New York Stem Cell Foundation, the Mt. Sinai Health Care Foundation and Case Western Reserve University School of Medicine.

Rackspace Looks To The Telcos In Global Expansion Of Its OpenStack Cloud
Rackspace is banking on service providers such as telcos for its global expansion, leveraging OpenStack to build out cloud infrastructures that partners will then charge customers for cloud offerings. Rackspace will provide an end-to-end program that will include the hardware and the OpenStack cloud operating system software for the build out. The company will provide continuous automated testing and delivery of updates from the Rackspace engineering teams. Rackspace will also manage infrastructure operations such as patching, tuning and monitoring. Rackspace CTO John Engates said in an email interview that if a large telco or service provider wants to become a public cloud provider, they have lots of options for the parts, but none of the sum: Until now, there has been no way for them to get all the pieces they need. They could go to a hardware company who will pull a tractor trailer full of hardware up to the loading dock, call a software company to buy licenses, an integrator to come put it all together, some business consultants to help figure out the go to market pieces, and maybe two years later get to market with something that they hope works. Then they have to figure out how to operate it long term, and build the engineering teams to continuously innovate the platform. What makes this different is that we’re giving them everything. The expansion in many respects is a blueprint for what could be an antidote to Amazon Web Service (AWS) considerable growth. Rackspace goal is to form a partner network that could act as one federated cloud that allows for the build out across multiple regions with OpenStack as the common operating system. “We want to spread as fast as possible,” said Scott Sanchez, director of strategy for Rackspace Open Cloud (OpenStack) at Rackspace Hosting in a phone interview last week. “This gets us into markets that are underserved.” In contrast, AWS has built out its own proprietary data centers around the world, treating them as one giant, programmable system. The contrasts show how AWS pushes a direct strategy while Rackpace is planning to go direct and work with service providers as channels to reach the end market. Marten Mickos is CEO at Eucalyptus Systems. His company competes with Rackspace and companies, such as VMware. His comments, also in an email interview, reflect a market still forming. It’s a difficult choice for customers. VMware isSource: http://feedproxy.google.com/~r/Techcrunch/~3/YVyWrhPRnb8/

Adam Scott Wins Masters With Birdie Putt On No ... - Business Insider
Adam Scott just won the Masters after burying two clutch putts down the stretch.
He's the first Australian to ever win a green jacket.
He drained a 20-footer on the 18th hole to move to -9 and earn a spot in the playoff with Angel Cabrera (GIF below).
Then, on the second playoff hole, he buried a 15-foot putt to win it.
It's ironic, since putting has always been the weakness of Scott's game.
Here's the final putt:

More coming ...
Here he is after winning (via @cjzero):
The ol' green jacket:
It was a dramatic finale.
Scott and Cabrera were tied at -8 going into the 18th hole.
After Scott drained a 20-foot putt to move to -9 and seemingly win the tournament, Cabrera hit his approach shot to within two feet.
He birdied and sent it to a playoff.
Scott thought he won the tournament:

A new chemical process can transform waste sulfur into a lightweight plastic that may improve batteries for electric cars, reports a University of Arizona-led team. The new plastic has other potential uses, including optical uses.
The team has successfully used the new plastic to make lithium-sulfur batteries.
"We've developed a new, simple and useful chemical process to convert sulfur into a useful plastic," lead researcher Jeffrey Pyun said.
Next-generation lithium-sulfur, or Li-S, batteries will be better for electric and hybrid cars and for military uses because they are more efficient, lighter and cheaper than those currently used, said Pyun, a UA associate professor of chemistry and biochemistry.
The new plastic has great promise as something that can be produced easily and inexpensively on an industrial scale, he said.
The team's discovery could provide a new use for the sulfur left over when oil and natural gas are refined into cleaner-burning fuels.
Although there are some industrial uses for sulfur, the amount generated from refining fossil fuels far outstrips the current need for the element. Some oil refineries, such as those in Ft. McMurray in Alberta, are accumulating yellow mountains of waste sulfur.
"There's so much of it we don't know what to do with it," said Pyun. He calls the left-over sulfur "the garbage of transportation."
About one-half pound of sulfur is left over for every 19 gallons of gasoline produced from fossil fuels, calculated co-author Jared Griebel, a UA chemistry and biochemistry doctoral candidate.
The researchers have filed an international patent for their new chemical process and for the new polymeric electrode materials for Li-S batteries.
The international team's research article, "The Use of Elemental Sulfur as an Alternative Feedstock for Polymeric Materials," is scheduled for online publication in Nature Chemistry April 14. The National Research Foundation of Korea, the Korean Ministry of Education, Science and Technology, the American Chemical Society and the University of Arizona funded the research.
Pyun and Griebel's co-authors are Woo Jin Chung, Adam G. Simmonds, Hyun Jun Ji, Philip T. Dirlam, Richard S. Glass and rpd Somogyi of the UA; Eui Tae Kim, Hyunsik Yoon, Jungjin Park, Yung-Eun Sung, and Kookheon Char of Seoul National University in Korea; Jeong Jae Wie, Ngoc A. Nguyen, Brett W. Guralnick and Michael E. Mackay of the University of Delaware in Newark; and Patrick Theato of the University of Hamburg in Germany.
Pyun wanted to apply his expertise as a chemist to energy-related research. He knew about the world's glut of elemental sulfur at fossil fuel refineries -- so he focused on how chemistry could use the cheap sulfur to satisfy the need for good Li-S batteries.
He and his colleagues tried something new: transforming liquid sulfur into a useful plastic that eventually could be produced easily on an industrial scale.
Sulfur poses technical challenges. It doesn't easily form the stable long chains of molecules, known as polymers, needed make a moldable plastic, and most materials don't dissolve in sulfur.
Pyun and his colleagues identified the chemicals most likely to polymerize sulfur and girded themselves for the long process of testing those chemicals one by one by one. More than 20 chemicals were on the list.
They got lucky.
"The first one worked and nothing else thereafter," Pyun said.
Even though the first experiment worked, the scientists needed to try the other chemicals on their list to see if others worked better and to understand more about working with liquid sulfur.
They've dubbed their process "inverse vulcanization" because it requires mostly sulfur with a small amount of an additive. Vulcanization is the chemical process that makes rubber more durable by adding a small amount of sulfur to rubber.
The new plastic performs better in batteries than elemental sulfur, Pyun said, because batteries with cathodes made of elemental sulfur can be used and recharged only a limited number of times before they fail.
The new plastic has electrochemical properties superior to those of the elemental sulfur now used in Li-S batteries, the researchers report. The team's batteries exhibited high specific capacity (823 mAh/g at 100 cycles) and enhanced capacity retention.
Several companies have expressed interest in the new plastic and the new battery, Pyun said.
The team's next step is comparing properties of the new plastic to existing plastics and exploring other practical applications such as photonics for the new plastic.
