Dr. Roach: Sensitivity to gluten causes celiac disease

Dear Dr. Roach: I have several symptoms of gluten intolerance. I?ve read that there are tests to confirm celiac disease. Besides a blood test, one test is a biopsy of tissue taken from the small intestine. How does the doctor retrieve such tissue? How reliable are the results of these tests after following a gluten-free diet? ? S.S.

Celiac disease, also called celiac sprue, is caused by a sensitivity to gliadin, a component of gluten, which is found in wheat, barley, rye and oats. The major symptoms are weight loss, diarrhea and abdominal distention and bloating. The diagnosis is usually made based on a combination of blood tests and a small-intestine biopsy, which is obtained via an endoscopy of the stomach and intestine.

Neither the blood tests nor the biopsy is perfect. In people who have been on a strict gluten-free diet, it is possible the antibody blood test and the biopsy return as normal. In this case, a blood test to determine genetic risk for celiac disease can be done.

Hello, Dr. Roach: I was diagnosed with stage III kidney disease in May 2012. I had been taking HCT for more than 10 years for hypertension; apparently it did not control my blood pressure well enough to ward off kidney damage. I have been prescribed Azor once a day. After taking it with the HCT for two weeks, my GFR (glomerular filtration rate) went down 10 points, although my BP is much better, usually less than 120/80. The drastic change in my GFR concerns me greatly. Is this medication worse than the illness? A few years ago, Vioxx was taken off the market because it caused damage and fatal results in some patients. Is this a similar medication? I would appreciate any advice you can give me. ? P.E.D.

This gets a little confusing, so bear with me. Azor is a combination of two medicines: amlodipine and olmesartan. Olmesartan is in the class of ARBs (angiotensin receptor blockers, which work by opening up constricted blood vessels), and these have the effect of reducing blood flow to the kidneys. GFR (glomerular filtration rate) is a measure of kidney function, and is directly related to the blood flow to the kidneys. So a medicine like olmesartan ? or any of the ARBs or ACE inhibitors ? will very often drop GFR. A lower GFR means a higher creatinine level, since creatinine is removed from the blood by the kidneys. Since a higher creatinine means worse kidney function independent of the medication effect, it?s natural for patients to worry that the kidneys are being damaged.

(AP) ? About once every three weeks, I watch someone die.

Beginning in 1984 when I arrived in Texas for The Associated Press, I've been just a few feet away as one convicted killer after another took a final breath in the Texas death chamber in Huntsville, where the state's 500th execution in modern times took place Wednesday.

I really don't know how many I've seen. I lost count years ago and have no desire to reconstruct a tally.

While death penalty cases are not the only assignments I cover, those certainly leave the strongest impressions.

One inmate, Jonathan Nobles, sang "Silent Night" as his last words as he was receiving the lethal injection. He got to "Round yon virgin, mother and child" before gasping and losing consciousness. Christmas, for me, never has been the same.

When I walked into the death chamber to witness Bob Black's execution, he called my name, said hello and asked how I was doing. What do you say to an otherwise healthy man seconds away from death?

J.D. "Cowboy" Autry was the first lethal injection I saw, in March 1984. A female friend of his who was a witness loudly sobbed about his "pretty brown eyes." Moments later, Autry's eyelids popped open as he died, revealing for a final time his brown eyes.

Autry's case was a memorable one. Six months earlier he was on the gurney with the needles in his arms when the U.S. Supreme Court issued a last-minute reprieve. To make sure no one had to make the final walk twice again, the prison stopped taking inmates to the death chamber until all appeals were resolved.

I remember Charles Rumbaugh's mangled hand, the result of being shot by a federal marshal he attacked in a courtroom. Henry Lee Lucas, who avoided execution when it was determined he hadn't really committed the hundreds of murders he had copped to, always had orange-tinged fingertips from rolling his own cigarettes. The arms of Angel Resendiz, the notorious "Railroad Killer," were scarred by repeated self-inflicted razor cuts. Markham Duff-Smith, who insisted he didn't kill four relatives, made a death chamber confession.

The death chamber, for 50 years home to the electric chair, has undergone its own changes. The gurney, once on wheels, is a permanent pedestal-like structure bolted to the tile floor. The simple horizontal bar between the inmate and the viewing area was replaced by a thick transparent plastic wall after a needle popped out of Raymond Landry's arm, spraying the lethal drugs toward me and other witnesses.

The first executions were carried out just after midnight. Years later, death warrants were set to take effect at 6 p.m., more convenient for lawyers and judges and less costly in prison overtime.

Some executions came with raucous public demonstrations outside. When Ronald Clark O'Bryan, known as "The Candy Man," was executed for lacing his son's Halloween candy ? a Pixy Stick ? with cyanide so he could collect on an insurance policy, dozens of students dressed in Halloween costumes filled the streets. One carried a giant Pixy Stick replica that looked like a barber pole.

One convict, Ponchai Wilkerson, spit out a hidden handcuff key in his mouth as he was about to die. A Houston judge added a smiley face to his signature on Robert Drew's execution warrant. Carl Kinnamon gave a long final statement in hopes of delaying the procedure until his death warrant expired. He thanked me and others for covering his case, then tried to wriggle out of the leather restraints.

The final statements ? which some victims' relatives have criticized as providing prisoners with an opportunity their slain loved ones never had ? have included songs, poems, prayers and Bible verses. Some inmates have spouted profanity. At least two prisoners thanked the Dallas Cowboys for brightening their lives.

Patrick Knight held a contest dubbed "Dead Man Laughing," encouraging people to send him a joke to tell from the chamber. He said he got 1,300 responses. The "joke" turned out to be Knight's claim that the person being executed wasn't really Patrick Knight. But fingerprints confirmed it was.

Richard Hinojosa repeatedly invoked "Yahweh" during his final words as thunder boomed and lightning crackled outside, adding an eerie backdrop to the proceeding.

Johnny Frank Garrett thanked his family for loving and caring for him, then added: "And the rest of the world can kiss my ass."

Pujols lifts Angels over Tigers 3-1 in 10 innings

DETROIT (AP) ? Albert Pujols got the biggest hit of the game. Jered Weaver delivered the most encouraging performance, as far as the Los Angeles were concerned.

Pujols hit a tiebreaking double in the 10th inning and the Angels beat Detroit 3-1 on Thursday for their ninth straight victory over the Tigers.

Mike Trout had four hits and was in the middle of the decisive rally for the Angels, who completed a three-game sweep. Weaver pitched seven strong innings in a tight duel with Detroit right-hander Doug Fister.

"Just wanted to concentrate on keeping things simple and keeping the mechanics sound and tried to locate," said Weaver, the staff ace who had struggled since coming off the disabled list.

Making his sixth start since returning from a broken left (non-throwing) elbow, Weaver gave up one run and four hits. He walked two and struck out six.

After the Tigers scored in the second, Weaver allowed only a hit and a walk in his final five innings. He retired his last 13 batters.

"We're confident that he's going to pitch more like he did today than the way he has in a couple of his last starts," Angels manager Mike Scioscia said.

J.B. Shuck singled leading off the 10th against Phil Coke (0-5) and went to third on Trout's single to right field. Pujols sent a drive to deep center, where Austin Jackson tried to make a difficult catch with his back to home plate.

The ball tipped off the webbing of Jackson's glove, hit the wall and trickled to the ground.

"That ball was crushed," Scioscia said.

After an intentional walk to Howie Kendrick loaded the bases, Josh Hamilton made it 3-1 with a sacrifice fly.

"The Pujols pitch wasn't a bad pitch. I think that maybe it wasn't the right pitch in that particular moment," Coke said. "I didn't feel like I made the perfect pitch to him by any means, but the last thing I thought he was going to do is hit it as far as he did. It was away from him. I looked at where (catcher Brayan) Pena was set up and he was going away from Pujols with his glove, going away to receive the ball. He found it with his barrel."

Kevin Jepsen (1-2) worked a scoreless ninth for the win and Ernesto Frieri got three outs for his 19th save in 21 chances.

Neither team could do much against the starters.

Scott Downs replaced Weaver and set down the leadoff man in the eighth. But Downs then allowed Omar Infante's pinch-hit double and hit Jackson with a pitch. Downs was pulled for Michael Kohn, who struck out former Angel Torii Hunter and Miguel Cabrera, both swinging, to end the inning.

"Having a situation with Torii, as clutch as they come, and then you've got the best hitter in the league up next," Scioscia said. "What he did to get out of that eighth inning was huge."

Fister yielded one run and seven hits in seven innings, walking one and striking out four. After the Angels tied the game in the fourth, he gave up only one hit in his final three innings and didn't allow a runner past second.

"He did a tremendous job. The fact that he was able to contain that offense, that shows that he's a good pitcher," Pena said. "He kept us in the ballgame and he gave us a chance to win the ballgame. That's what you ask. He pitched beautifully."

Fister was relieved by Al Alburquerque, who pitched a scoreless eighth. The Angels got runners to second and third with two outs in the ninth against Joaquin Benoit, but he struck out Erick Aybar swinging at a 3-2 pitch to get out of the jam.

Detroit took a 1-0 lead in the second on Brayan Pena's two-out RBI single. It scored Victor Martinez, who singled with one out and went to second when Jhonny Peralta followed with a single.

Los Angeles tied it in the fourth on three consecutive singles to start the inning. Brad Hawpe's single to right scored Hamilton from third. Alberto Callaspo was thrown out at third by Hunter on the play.

NOTES: Los Angeles placed RHP Tommy Hanson on the 15-day disabled list. Hanson was scratched from his scheduled start Wednesday night when he felt tightness in his right forearm while warming up in the bullpen. Scioscia said Hanson (4-2, 5.10 ERA) would have an MRI on Thursday. The team recalled LHP Michael Roth from Double-A Arkansas. ... Detroit RHP Anibal Sanchez, on the 15-day DL with a right shoulder strain, threw to batters before the game. ... Cabrera is the sixth player since 1920 with 1,200 RBIs and 300 home runs in his first 11 seasons. The others were Hank Aaron, Ted Williams, Joe DiMaggio, Jeff Bagwell and Pujols. ... Cabrera went 1 for 4 on Thursday to extend his hitting streak to 12 games, which tied a season high. ... The Tigers begin a three-series road swing this weekend at Tampa Bay. Max Scherzer looks to run his record to 12-0 on Friday night when he faces Alex Colome (1-0, 0.00 ERA). ... The Angels head for Houston, where Jerome Williams (5-3, 3.36) will oppose Astros RHP Bud Norris (5-7, 3.60).

Efficient production process for coveted nanocrystals

June 25, 2013 ? A formation mechanism of nanocrystalline cerium dioxide (CeO2), a versatile nanomaterial, has been unveiled by scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the University of New South Wales in Sydney, Australia.

The research results were published in the scientific journal Chemistry -- A European Journal. This finding potentially simplifies and alleviates the existing synthetic processes of nanocrystalline CeO2 production.

Nanocrystalline CeO2 particles are widely used, for example, in catalysts for hazardous gas treatment, in electrodes for solid oxide fuel cells, in polishing materials for advanced integrated circuits, in sunscreen cosmetics, and in such medical applications as artificial superoxide dismutase. Current industrial syntheses of nanocrystalline CeO2 are based on sol-gel processes followed by thermal treatment and/or the addition of accelerant reagents. Any further improvement of the synthetic strategy for CeO2 nanocrystals requires a better understanding of the mechanisms involved in their formation at the atomic scale.

Dr. Atsushi Ikeda-Ohno from the University of New South Wales, Australia, together with Dr. Christoph Hennig from the HZDR opted for a sophisticated multi-spectroscopic approach that combines dynamic light scattering and synchrotron-based X-ray techniques. These complex investigations involved the use of two world-leading synchrotron facilities of the European Synchrotron Radiation Facility (ESRF) in Grenoble, France and SPring-8 in Hyogo, Japan.

Live Monitoring

For the first time ever, the scientists were able to perform an in-situ observation of nanocrystal evolution. So far, little has been known of the formation mechanism of metal nanocrystals; mainly because appropriate analytical techniques were lacking. The most widely used techniques for metal nanocrystal research are electron microscopy and X-ray diffraction. They are powerful enough to visualize the appearance of nanocrystals and to acquire their lattice information, but they are not applicable to the solution state where the evolution of metal nanocrystals occurs. "To probe the formation of nanocrystalline CeO2 in an aqueous solution, we combined different spectroscopic techniques, including dynamic light scattering, synchrotron X-ray absorption spectroscopy, and high energy X-ray scattering," says Dr. Atsushi Ikeda-Ohno.

The information the researchers obtained is fundamental to simplifying and alleviating the synthetic process of CeO2 nanocrystals. They revealed that uniformly sized nanoparticles of CeO2 can be produced simply by pH adjustment of tetravalent cerium (Ce(IV)) in an aqueous solution without subsequent physical/chemical treatment such as heating or adding accelerant chemicals. The produced CeO2 crystals have a uniform particle size of 2 -- 3 nanometers, irrespective of the preparation conditions (e.g. pH and type of pH adjustment). This particle size is exactly in the range which is interesting for industrial applications. A key finding is that mononuclear Ce(IV) solution species do not result in nano-sized CeO2 crystals. The prerequisite is the presence of oligomeric Ce(IV) solution species, such as dimers or trimers.

"We're indeed very glad that our multi-spectroscopic approach is also applicable to any other research on metal nanocrystals. That's why this study contributes to an emerging research area on metal nanocrystals in a broader context," says Dr. Christoph Hennig. "And the HZDR's own measuring station at the ESRF provides the best possible opportunities for this research area of metal nanocrystals which directly contributes to industrial applications."

(AP) ? For Syrians, no visit to Damascus' Old City is complete without a stop at a more than century-old ice cream parlor in its main souq where you can watch them make their distinctive desert by pounding it into shape with giant wooden mallets, then enjoy a bowl of it sprinkled with pistachios.

Now those who fled their country's bloody civil war can savor a nostalgic taste from back home. Damascus' most famed ice cream shop, Bakdash, has opened a branch in the Jordanian capital, and both Jordanians and Syrians living here are flocking to it.

With its mix of milk, gum Arabic and sahlab ? a flour made from orchids ? Bakdash ice cream is distinct from American brands like Ben & Jerry's and H?agen-Dazs, which also typically ignite a craze when they open outlets in the Middle East. The traditional Syrian ice cream has a more elastic texture and slightly more perfumed flavor than the Western versions.

The Damascus landmark's appearance in Jordan is a bittersweet sign of one of the civil war's tragic repercussions: The dispersal of Syria's population and culture. Jordan alone is home to more than half a million Syrians, out of nearly 2 million who have fled into neighboring countries with no immediate prospects of return. The number is rising by the thousands daily, as life in Syria becomes more tenuous.

Things are not easy even in Damascus, the core of President Bashar Assad's regime, with prices mounting and the currency draining value.

Bakdash's owners ? the third generation of the Bakdash family ? still keep the Damascus parlor running. But they have set up shop in Jordan and the United Arab Emirates, hoping the new businesses will help keep the store at home afloat. The stores abroad could also be insurance for the future as the war, now in its third year, batters Syria's economy and annihilates all traces of tourism.

In Damascus before the war, a visit to the Bakdash parlor topped the to-do lists for Syrians, tourists and other visitors exploring the winding alleys of the capital's fabled Old City. Since 1895, the shop has been a fixture in the Souq al-Hamidiya, the Old City's main traditional market.

For Basima, a housewife who fled Syria seven months ago to Jordan, running across the branch in Amman was a cherished touch of home.

"We were walking outside along the street and saw Bakdash. It reminded us of when we would walk in the Souq al-Hamidiya," she said as she spooned into a creamy bowl at the parlor this week. She asked to be identified only by her first name to protect her family still in Syria.

"Any name from Syria sounds wonderful to us," said the 45-year-old woman, wearing a traditional headscarf. "My heart beats faster whenever I see Syrians ... When I meet other Syrians here in the parlor, I feel my spirit lift."

A Sunni Muslim ? the community that makes up the majority of the rebellion ? she fled her Damascus neighborhood after violence hit the capital. "There were clashes near where we lived. It wasn't safe anymore. There was no safe place to go there," she recalled.

About half of the customers are Syrians, said the Amman branch's assistant manager, Yarob Ababneh, whose father is Bakdash's Jordanian partner. The Amman parlor opened last month.

"Once or twice I saw people cry" he said. "Bakdash has been in Syria since 1895, so those who grew up there know the place and have been there many times."

Getting to the Jordanian branch is a far cry from a charming meander through Old Damascus ? it's located on a popular but traffic-clogged shopping thoroughfare. But once inside, a visitor is transported to the ambience of the Syrian original.

Waiters rush about carrying large trays with glasses brimming with "booza," the traditional Arab ice cream. Black basalt and ochre-colored natural stones line the walls while customers sit at metal tables.

In front of the customers, Syrian ice cream makers ? traditionally, a man's job ? pound the booza with large wooden mallets inside metal containers to get it into shape. Sometimes, the pounding sound resembles the fierce drumbeat of a belly-dancing rhythm, to the customers' delight.

It's then scooped and topped with finely chopped green pistachios ? and the taste, some say, can touch heartstrings.

The ice cream base arrives in refrigerated trucks overland from Syria, sometimes at great risk crossing the volatile border, Ababneh said.

"We deal with a shipping company. They make their calls to ensure that the road is safe before the truck travels. We stay in contact with the drivers hour by hour," he said. "It is dangerous, but what can we do? The drivers take the risk and we pay them for that."

Hamza Hashish, 20, is one of Bakdash's best "pounders." He started working at the Damascus shop when he was just 12, so short he had to "stand on a box" just to reach the ice cream, he said.

As fierce fighting between Syrian rebels and Assad's troops made it increasingly difficult for Hashish and other employees to get to work, he decided to try his chances in Jordan. "Some of the workers were killed on the way, others joined the rebels," he said.

Even the safety of being out of Syria can't keep him from longing for home. In between pounding at the Bakdash branch in Amman, Hashish reminisces with other Syrians.

Jordanians familiar with the ice cream also cram the Amman store.

Amman taxi driver Raad Abdel-Majid said whenever he and his family used to visit Damascus, one of the first things they would do once they got there was "rush over to Bakdash for ice cream."

"While we really hope the crisis will soon end, I am ecstatic that Bakdash has opened its doors here," said Abdel-Majid.

If you visit one of the public schools in Mooresville, N.C., you can get a glimpse into what the classroom of tomorrow might look like. A high-speed broadband network, personalized software, and laptops for every student allow each member of the class to learn at his or her own pace while teachers receive real-time feedback about their learners? progress. That?s why President Barack Obama went to Mooresville in early June to launch a new initiative called ConnectED, which aims to bring similar next-generation connectivity to classrooms across America in the next five years.

?In an age when the world?s information is just a click away, it demands that we bring our schools and libraries into the 21st century,? Obama declared in his speech at Mooresville Middle School. ?We can't be stuck in the 19th century,? he said, referring to the sad state of broadband connectivity at most of America?s schools. It?s a great idea. But Obama?s proposal leaves a lot of questions unanswered. The biggest unknown is perhaps the most important: funding. How the money is spent and where it comes from will determine not only whether the program meets its benchmarks but also whether it really helps ensure that ?every child in America?s classrooms has access to the fastest Internet and the most cutting-edge learning tools.?

The administration has indicated that it will let the FCC figure out those details. ConnectED would be part of the commission?s E-Rate program, which provides subsidies to broadband providers to offer discounted service to schools and libraries. E-Rate, in turn, is part of the Universal Service Fund, which administers several programs to bring better access to telecommunications services across the country, especially in low-income, rural, insular, and high-cost areas.

In the past two decades, E-Rate has helped connect thousands of schools and libraries, but the program is now struggling to meet growing demand. Currently, most of the schools that receive E-Rate funding have connection speeds that are similar to those of the average home broadband user?a far cry from what they need to support large numbers of students using the next generation education applications being developed for classrooms. (It?s an even farther cry from ConnectED?s stated goal of providing 99 percent of America?s schools and libraries with minimum speeds of 100 Mbps per 1,000 students and a target of 1 Gbps by 2018.) In fact, in a survey of E-Rate subsidized schools, nearly 80 percent reported that they did not even have the bandwidth to meet their current needs, let alone to account for future growth. As FCC Commissioner Jessica Rosenworcel said recently, ?The problem now is not connection, it?s capacity.?

One challenge is that the program needs to ensure that schools upgrade to technology that won?t become obsolete in just a few years, like cable or wireless. Fiber is the only option that remains largely future-proof: It?s already capable of gigabit speeds and more readily scalable than other technologies to meet future demands.

The FCC should also carefully consider who would be the best stewards of E-Rate dollars. Large phone companies haven?t always proven themselves reliable in that regard, charging some schools up to 325 percent more than they charged others in the same region for essentially the same services. And the cable companies don?t even think gigabit speeds are necessary (a convenient perspective when your service relies on technology that is incapable of actually achieving those speeds). In reality, projects like Google Fiber and community networks in Chattanooga, Tenn.; Lafayette, La.; and Santa Monica, Calif.; where cities have invested in fiber infrastructure that can then be leveraged by area school districts, tend to have the fastest speeds?and these sorts of alternative models should be supported. E-rate ought to be used primarily to support substantial upgrades to infrastructure?the high investment costs that most broadband providers use to justify what they charge per month?and in return require that the network providers offer free or heavily discounted services to the schools..

So where will the money come from? President Obama?s remarks in Mooresville last Thursday and a supplemental fact sheet are notably light on details. There may be a temporary increase in the surcharge that you pay on your monthly phone bill (or bills, since it?s applied to both landline and mobile plans) to pay for the ?one-time investment.? Commissioner Rosenworcel has also suggested that savings from recent reforms in the Lifeline program (which is part of the Universal Service Fund and provides discounts for telephone service for eligible low-income households) should be used to support her version of the proposal called E-Rate 2.0, while several news articles refer to ?rechanneling? funds from Lifeline. Sen. Claire McCaskill, D-Mo., has even called for eliminating the Lifeline program entirely and moving all funds to the E-Rate program.

However, none of these ideas are very promising, and the call to reduce or eliminate Lifeline entirely is particularly troubling. Finding the money under the existing USF system will be difficult, and even a small increase on monthly phone bills that are already steadily rising could be problematic. And while the Lifeline program has faced some criticism, many of the problems have already been addressed by FCC reforms. Importantly, the program is currently underutilized by eligible users, and any restrictions in funding will hinder its ability to support broadband access in the future.

But ConnectED?s success will also depend on home access. Obama recognizes that students? connectivity needs to extend beyond school walls. In his remarks, he imagines ?a young boy with a chronic illness that means he can't go to school [who now] can join his classmates via Skype or FaceTime and fully participate in what's going on??a scenario that would require robust connectivity at the student?s home as well as his school. Mooresville has addressed the problem of home broadband access by convincing a local, community-owned cable company to offer broadband access to students? families for $9.99 a month, plus free Wi-Fi connections in parks, local libraries, and municipal buildings. If the Lifeline program were updated to support stand-alone broadband service, it could mean that low-income students could have broadband access in schools and other public areas, as well as complementary access at home. Simply moving funds from one Universal Service Fund program to another could cripple Lifeline?s ability to support existing service and make it much more difficult for it to support home broadband service in the future.

The ConnectED program has the potential to dramatically improve broadband access for schools across the country, but its goals won?t be achieved by tinkering at the edges of existing programs, or relying on models that have already proven inadequate.

Crews working to get more Colo. fire evacuees home

COLORADO SPRINGS, Colo. (AP) ? Firefighters are working to get more people back into their homes after authorities lifted evacuations orders prompted by the wildfire near Colorado Springs.

Crews on Sunday were extinguishing hot spots to protect undamaged homes in Black Forest from flare ups. Meanwhile, utilities were working to restore gas and electricity to the heavily-wooded region.

Residents of areas burned by the fire, now estimated to be about 22 square miles, were able to return briefly to see the devastation Saturday. Evacuees outside the burn area have been allowed back for good.

Nearly 500 homes have been burned by the fire, and two people were killed. Crews hope to have it fully contained by Thursday.

NASA tests radio for unmanned aircraft operations

June 17, 2013 ? NASA's communications experts have begun flight testing a prototype radio as part of the agency's contributions toward fully integrating civil and commercial Unmanned Aircraft Systems (UAS) into the National Airspace System (NAS).

This particular radio is one of the first steps to provide the critical communications link for UAS pilots on the ground to safely and securely operate their remotely piloted vehicles in flight even though they are many miles -- if not continents or oceans -- apart.

"So far the tests are going well and we're learning a lot about how this prototype radio operates under various conditions, but we still have much more testing to do on this radio and others that will come," said Jim Griner, a project engineer at NASA's Glenn Research Center in Cleveland.

Currently there is not a great deal of freedom for civilian uses of UAS over our nation's skies. Police and firefighters, for example, must use off-the-shelf systems and fly under special Federal Aviation Administration (FAA) approvals that restrict where and when remotely piloted vehicles can fly.

"There are some pretty good limitations on those operations, but the work we're doing to develop a new command and control radio for the UAS to use will help go beyond that," Griner said.

Built under a cooperative agreement between NASA and Rockwell Collins in Iowa, the current prototype radio is a platform to test operations at certain frequencies with specific radio waveforms that are unique to its particular task -- in this case command and control of a remotely piloted vehicle.

Once testing concludes on the initial prototype, lessons learned will be applied to a second generation test radio, which is now scheduled to be delivered to NASA in September. Additional testing will follow, after which a final prototype design is to be delivered and tested in the 2015-2016 timeframe.

Ultimately the FAA will define the final requirements that will lead to certification of a UAS command and control radio for use in the NAS, but by building and testing prototype units now NASA is helping move the process along.

"Usually the requirements are defined first and then we try to build equipment based on those requirements. This short-circuits a number of years off the traditional process," Griner said.

The prototype radio was delivered to NASA Glenn on Feb. 28 and successfully put through its paces on a laboratory test bench. Flight tests in a NASA S-3 Viking twin-engine jet began in May and are expected to continue in June.

Tests of the prototype radio were preceded by a number of flights of the S-3 in which NASA researchers sought to characterize the way radio frequencies behave at the specific bandwidths assigned to civil UAS operations -- something that had not been done before.

The way radio waves move through the air can be affected by a number of different things, including whether the ground is covered with leafy trees or snow and ice. Mountains, oceans, weather conditions, urban sprawl, skyscrapers and more can cause a change in a radio signal, for a good or bad.

These channel characterization flights began last December with the S-3 flying over areas of Ohio and Pennsylvania while a specially outfitted trailer with a 60-foot deployable antenna mast transmitted signals from the ground below.

With the prototype radio now in hand, the channel characterization and prototype radio tests will overlap a bit as there are plans for a visit to California this month to record data over coastal feature areas that include the ocean, mountains and desert.

NASA's UAS in the NAS Project is part of the Aeronautics Research Mission Directorate's Integrated Systems Research Program.

Obama: Northern Ireland peace will be tested

(AP) ? President Barack Obama declared peace in Northern Ireland a "blueprint" for those living amid conflict around the world, while acknowledging that the calm between Catholics and Protestants will face further tests. Summoning young people to take responsibility for their country's future, Obama warned there is "more to lose now than there's ever been."

"The terms of peace may be negotiated by political leaders, but the fate of peace is up to each of us," Obama said Monday during remarks at Belfast's Waterfront Hall. The glass-fronted building would never have been built during the city's long era of car bombs.

Obama arrived in Northern Ireland Monday morning after an overnight flight from Washington. Following his remarks in Belfast, he was bound for a lakeside golf resort in Enneskillen for meetings with other leaders of the Group of 8 industrial nations on Syria, trade and counterterrorism. Later Monday, Obama was meeting one-on-one with Russian President Vladimir Putin, British Prime Minister David Cameron and Italian Prime Minister Enrico Letta.

Cameron selected Enniskillen as the site of this year's meeting as a way to highlight Northern Ireland's ability to leave behind a four-decade conflict that claimed 3,700 lives.

Significant progress has been made in the 15 years since the U.S.-brokered Good Friday Accords, including a Catholic-Protestant government and the disarmament of the IRA and outlawed Protestant groups responsible for most of the 3,700 death toll. But tearing down Belfast's nearly 100 "peace lines" ? barricades of brick, steel and barbed wire that divide neighborhoods, roads and even one Belfast playground ? is still seen by many as too dangerous. Obama cited that playground in his speech, lauding an activist whose work led to the opening of a pedestrian gate in the fence.

Acknowledging the reality of a sometimes-fragile peace, Obama recalled the Omagh bombings that killed 29 people and injured hundreds more. It was the deadliest attack of the entire conflict and occurred after the Good Friday deal.

Peace will be tested again, Obama said.

"Whenever your peace is attacked, you will have to choose whether to respond with the same bravery that you've summoned so far or whether you succumb to the worst instincts, those impulses that kept this great land divided for too long. You'll have to choose whether to keep going forward, not backward," he said.

Last month, the Catholic and Protestant leaders of Northern Ireland's unity government announced a bold but detail-free plan to dismantle all peace lines by 2023. British Prime Minister David Cameron formally backed the goal Friday, and Obama followed with his own endorsement Monday.

The president specifically endorsed an end to segregated housing and schools, calling it an essential element of lasting peace.

"If towns remain divided ? if Catholics have their schools and buildings, and Protestants have theirs, if we can't see ourselves in one another, if fear or resentment are allowed to harden ? that too encourages division. It discourages cooperation," Obama said.

One symbol of that effort to end the segregation was on display as Obama spoke to an audience that brought together students from both faiths, effectively integrating Northern Ireland's schoolchildren if just for a morning.

Drawing on America's own imperfect battle with segregation, Obama recalled how a century after the U.S. Civil War, the nation he leads is still not fully united. His own parents ? a white woman from Kansas and a black man from Kenya ? would not have been able to marry in some states, Obama said, and he would have had a hard time casting a ballot, let alone running for office.

"But over time, laws changed, and hearts and minds changed, sometimes driven sometimes by courageous lawmakers, but more often driven by committed citizens," he said.

Though Obama did not specifically mention Syria, his remarks on Northern Ireland recalled the fierce conflict there that has so far resulted in 93,000 deaths. For those looking for a way out of conflict, Obama said Northern Ireland is "proof of what is possible."

Obama and other G-8 leaders were expected to discuss Syria Monday night over a working dinner. Obama will be looking to Britain and France to join him in sending weapons to the Syrian opposition.

Casting a shadow over the summit are new revelations by the Guardian newspaper that the British eavesdropping agency GCHQ repeatedly hacked into foreign diplomats' phones and emails when the U.K. hosted international conferences, including a 2009 Group of 20 summit in London. The report follows recent disclosures about the U.S. government's own surveillance programs and could lead to awkward conversation as the leaders open another international gathering that Britain is hosting.

Despite an agenda devoted to trade, economic growth and international tax issues, the G-8 will be eclipsed by discussions over how to address the two-year-old civil war in Syria and the decision by the United States to begin supplying rebels with military aid.

Obama's meeting with Russia's Putin later Monday will highlight the rift between their countries in addressing fierce fighting in Syria. While Putin has called for negotiated peace talks, he has not called for Syrian President Bashar Assad to leave power, and he remains one of Assad's strongest political and military allies.

In a likely preview of his discussions with Obama, Putin defended Russia's continuing supply of weapons to Assad's military in a meeting Sunday with Cameron, the British leader.

Putin said Russia was providing arms "to the legitimate government of Syria in full conformity with the norms of international law."

The White House is not expecting any breakthrough with Putin on Syria during Putin's meeting with Obama.

Obama is making his first visit to Northern Ireland, though he visited the neighboring Republic of Ireland in 2011. That trip included a public speech in the center of Dublin, as well as a stop in the village of Moneygall, where Obama's great-great-great grandfather was born. The president called that visit "magical."

First lady Michelle Obama and daughters Malia and Sasha, who also made the trip from Washington, were to spend Monday and Tuesday in Dublin while the president attended the G-8 summit. Later Tuesday, the first family departs for Germany, where the president will meet with Chancellor Angela Merkel and speak at the Brandenburg Gate.

Colo. wildfire evacuees see destruction firsthand

COLORADO SPRINGS, Colo. (AP) ? Residents returning to the neighborhoods they were driven from just days ago by Colorado's most destructive wildfire ever are seeing firsthand the path of destruction left behind by the flames.

Firefighters battling the fire in a rural region northeast of Colorado Springs have made huge advances in recent days, aided by unexpected rain showers and calmer winds, and authorities lifted most evacuation orders. Fire crews expanded containment lines Saturday to 55 percent.

Jack and Judy Roe thought their home was among the nearly 500 destroyed but found it standing amid other scorched houses in their neighborhood.

"We've been on such an emotional roller coaster over this thinking we had lost everything and then to find out that it's still there. It was a big relief to us, but I mean, our hearts were breaking for our neighbors," Judy Roe said. Describing the scene, she said she saw charred piles of what remained of homes, with bricks the only distinguishable feature.

Bob and Barbara Metzger lost their home, while nearby by their SUV, clotheslines and surrounding trees were spared.

"As long as the world around me looks the same, I'll be fine," Barbara Metzger said, showing a photo of her burnt home with surviving trees around. "We'll rebuild."

Authorities have also gained a clearer picture of a grim landscape in a burn area covering 25 square miles.

El Paso County Sheriff Terry Maketa said the fire's destruction has made it difficult for his deputies to assess damage. Deputies have said "it looks like a nuclear bomb went off in some of those areas, and you can't even recognize whether it was a house or some other kind of structure," Maketa said. "That is the level of incineration and destruction that took place in some areas."

The fire exploded Tuesday amid record-setting heat and tinder-dry conditions. Two people have died, their bodies found inside their garage Thursday. Their car doors were open as though they had been about to flee, authorities said.

It's unknown what sparked the blaze, but investigators believe it was human-caused. So far, it's cost more than $3.5 million to fight.

On Saturday, worried residents waited for permission to return to their neighborhoods to see the damage. They also worried about potential looters as Maketa tried to reassure them, saying deputies are on patrol.

"We have not let up any of our security efforts," he said.

The site of the wildfire is only a few miles away from the state's second most destructive wildfire, the Waldo Canyon Fire, which burned last summer.

The lessons from that fire spurred a quicker response, officials said. When the latest wildfire began in Black Forest, a thickly wooded rural region northeast of Colorado Springs, authorities swiftly evacuated tens of thousands of people from an area larger than the Denver metropolitan area.

White House officials said Saturday that President Barack Obama called Gov. John Hickenlooper on Friday to get an update on conditions and reinforce his commitment to help. The president also expressed his concern for the devastation and gave his condolences to families who have lost relatives.

Elsewhere in Colorado, fire crews worked to contain other smaller wildfires. In Canon City, 50 miles southwest of Black Forest, the Royal Gorge Fire burned 5 square miles and was 65 percent contained. A lightning-sparked fire in Rocky Mountain National Park had burned nearly 500 acres and was 30 percent contained.

Google Launches Cloud SQL API To Allow Developers To Manage Their Databases Programmatically

google_cloud_logoGoogle's Cloud Platform has long featured Cloud SQL, a zero-maintenance MySQL database that's hosted on Google's cloud platform. What it didn't offer was an API to easily manage these databases without having to use Google's admin interface. Today, however, Google is launching the Cloud SQL API. This new REST API will allow developers to programmatically manage their database instances and open up a number of new use cases for Cloud SQL.

Indians SS Asdrubal Cabrera injures right leg

NEW YORK (AP) ? Cleveland Indians shortstop Asdrubal Cabrera has been helped off the field at Yankee Stadium after straining his right quadriceps while running to first base on a groundout in the fifth inning.

Cabrera pulled up limping about two-thirds of the way down the line Monday night when he was trying to beat out a grounder up the middle. Robinson Cano fielded the ball behind second base and his throw across his body was in time for the second out. Cabrera, a two-time All-Star, immediately went to the ground holding his leg.

He was checked out by a trainer and manager Terry Francona, then tried to walk off the field with an arm around each. But Cabrera had to stop. He then made the remainder of the trip to the dugout putting weight only on his left foot.

Storm chasing critical, profitable and dangerous

OKLAHOMA CITY (AP) ? While most people take shelter when a tornado approaches, a growing throng heads for the prairies, be they scientists hoping to protect the public from a twister's fury or amateurs armed with little more than a smartphone, a digital camera and a desire to sell 15 seconds of video to the nightly news.

But the deaths of three respected researchers near Oklahoma City have renewed questions over whether the risk of dashing off into violent storms in Tornado Alley is too great ? regardless of the adrenaline rush.

"I think there will be some who will step back and say: 'Am I really doing something safe here?'" said Michael Armstrong, a meteorologist for KWTV in Oklahoma City. "I think you'll probably have others ... that just feel that invincibility that they've always felt and they'll keep doing what they're doing and basically look at it as though it was an aberration or an outlier."

Longtime storm chasers Tim Samaras, his son Paul and colleague Carl Young were killed Friday when a powerful tornado near El Reno, Okla., turned on them as they were conducting research. The National Weather Center issued a statement saying they are likely the first "storm intercept fatalities" among researchers.

Oklahoma is considered the "mecca of storm chasing," Tim Samaras told National Geographic just last month, and there are often hundreds of storm chasers lining the roads. Seasoned storm trackers provide critical field data that can't be gleaned from high-powered Doppler radar, veteran meteorologists say. But they're increasingly competing with storm-chasing tours, amateur weather enthusiasts inspired by cable TV shows and tornado paparazzi speeding from storm to storm.

Samaras' colleagues said he took numerous safety precautions, spending hours looking at weather models and developing safe escape routes and rendezvous points. All were done in case his crew would have to pull away from a tornado and use well-maintained roads that wouldn't turn into "pancake batter" in rain.

"Storm chasing isn't about what you see on TV. It's about forecasting and safety preparation," said Ben McMillan, a storm chaser from Des Moines, Iowa, who teamed up in 2011 with Samaras and Ed Grubb of Thornton, Colo., for the Discovery Channel show "Storm Chasers"

Samaras also usually drove a three-quarter ton truck with a reinforced lining, Grubb said, but had a smaller truck last week because he was on a three-week research trip focused mostly on lightning.

Many amateur storm chasers are looking to capture heart-pounding video of a massive, dangerous twister and cash in by selling the footage to television stations or documentary filmmakers. TV stations and other news outlets generally pay up to $500 to use certain video, and storm chasers will reach out to several different ones. Sometimes they're not even after money, but hearing their name read aloud on the air.

Lanny Dean, a 23-year veteran storm chaser from Tulsa, Okla., charges up to $3,500 to give tourists a 10-day tour during the March through June storm season. He said he's seen the industry change dramatically with the rise of TV programs documenting deadly storms.

"There are more and more people out there on the road. Many of them should not be," he said. "We're talking about individuals who are not experienced and who have no clue what they're doing. Friday's event was certainly no exception."

Dean and seven of his tourists found themselves near El Reno last week on the jam-packed roads when the deadly twisters began to drop from the sky.

"I saw a kid standing in the back of a Chevy pickup truck filming this thing as they're driving toward the tornado," Dean said. "I thought, my God, how stupid are these people?"

Friday's storm was particularly treacherous because the rotation was wrapped in rain, made frequent sudden turns and spawned multiple tornadoes. Eighteen people died, including several who were in their vehicles when the tornado hit.

"This storm had everything you could handle at one time," said Rick Smith, warning coordination meteorologist at the National Weather Service in Norman. "This was one of the craziest storms I've ever worked.

"It's just Oklahoma weather at the end of May. We had the perfect blend of ingredients."

Professors at the University of Oklahoma's School of Meteorology strongly discourage their students from storm chasing and rarely bring them into the field for research unless it's part of a well-planned, coordinated project.

"I can tell you that from a university perspective, we do not condone storm chasing at all. It's not something we teach in classes," said Melissa Bird, spokeswoman for OU's College of Atmospheric and Geographic Sciences. "It's dangerous, and students are not considered weather experts."

In the end, meteorologists, like Armstrong, believe storm trackers play an important role in keeping the public safe.

"There are aspects of it where storm chasers and storm trackers are always going to play a vital role in the warning process," Armstrong said. "But it is inherently dangerous to be around these storms."

Both Grubb and McMillian said they would continue chasing storms, despite their colleagues' deaths. Grubb, who started chasing storms in 1974, acknowledged the thrill was part of the attraction.

"It's like a magic show watching the clouds do this," he said.
