US tries new aerial tools in Caribbean drug fight

ABOARD THE HIGH SPEED VESSEL SWIFT (AP) ? Drug smugglers who race across the Caribbean in speedboats will typically jettison their cargo when spotted by surveillance aircraft, hoping any chance of prosecuting them will vanish with the drugs sinking to the bottom of the sea.

That may be a less winning tactic in the future. The U.S. Navy on Friday began testing two new aerial tools, borrowed from the battlefields of Afghanistan and Iraq, that officials say will make it easier to detect, track and videotape drug smugglers in action.

One of the devices on display aboard the High Speed Vessel Swift is a large, white balloon-like craft known as an aerostat, which is tethered up to 2,000 feet (600 meters) above the ship's stern. The other tool on board for tests in the Florida Straits is a type of drone that can be launched by hand from the deck.

Together, they expand the ability of Navy and Coast Guard personnel to see what's beyond their horizon, according to officials from both military branches and the contractors hoping to sell the devices to the U.S. government.

The devices should allow authorities to detect and monitor suspected drug shipments from afar for longer sustained periods, giving them a better chance of stopping the smugglers. They also should allow them to make continuous videotapes that can be used in prosecutions.

"Being able to see them and watch what they are doing even before we get there is going to give us an edge," said Chief Chris Sinclair, assistant officer in charge of a law enforcement detachment on board the Swift, a private vessel leased to the Navy that is about to begin a monthlong deployment to the southwestern Caribbean, tracking the busy smuggling routes off Colombia and Honduras.

Crews practiced launching and operating both systems before a small contingent of news media on board the Swift, managing to bring back video of vessels participating in a mock surveillance mission as well as radar and video images of the fishing charters and sailboats that dot the choppy seas separating Cuba from the U.S. mainland.

The drone, officially a Puma All Environment unmanned aircraft system from Aerovironment Inc. of Simi Valley, California, splashed into the water on one landing and had to be retrieved. On the second round, it clacked noisily but intact on the shifting deck of the 321-foot ship. Rear Adm. Sinclair Harris, commander of the Navy's 4th Fleet, said the devices are necessary at a time when the service is making a transition to smaller, faster ships amid budget cuts.

The aerostat, formally the Aerostar TIF-25K and made by a division of Raven Industries Inc. of Sioux Falls, South Dakota, is filled with helium. It's an old technology, models of which have been used for decades, but it's packed with cameras and sensors that expand the ship's radar capability from about 5 miles (8 kilometers) to about 50 miles. That can help teams in an on-board control center to identify larger ships, which now would appear as just dots on the horizon, from as far as 15 miles (25 kilometers) away.

The Puma, meanwhile, can be sent out to inspect a vessel flagged by the larger aerostat and give a "God's eye view," of what's happening on board, a job usually handled by a plane or helicopter, said Craig Benson, director of business development for the company.

Both the aerostat and the drone have been used widely by the U.S. government for overseas actions, but Harris and others aboard the Swift said neither has been used before by the Navy to conduct counter-drug operations.

Unmanned aerial devices, however, are not new to the drug fight. U.S. Customs and Border Protection operates 10 Predator drones, including two based in Cape Canaveral, Florida, that patrol a wide swathe of the Caribbean through the Bahamas and down to south of Puerto Rico. It deployed one to the Dominican Republic last year for six weeks and has considered using one in Honduras. The others are used along the northern and southern borders of the United States.

The U.S. military has long been deeply involved in counter-drug operations in the Southern Hemisphere, coordinated by a multi-agency task force based in Key West, Florida. Navy ships and Air Force jets use their radar to track and run down smugglers, though for legal reasons the actual arrests are carried out by the Coast Guard, civilian agencies or officials from other countries.

In March, the military said it would reduce patrols and sorties in Latin America and the Caribbean because of the automatic spending cuts imposed by Congress, another argument for increased use of aerial surveillance devices like the aerostat and drone, officials said.

Representatives on the Swift from both contractors declined to say what their systems cost. But they said each can be run at a fraction of the cost of the fixed-wing planes or helicopters usually dispatched to check out suspected smugglers.

Intermittent fasting may help those with diabetes and cardiovascular disease, study suggests

Apr. 26, 2013 ? Intermittent fasting is all the rage, but scientific evidence showing how such regimes affect human health is not always clear cut. Now a scientific review in the British Journal of Diabetes and Vascular Disease published by SAGE, suggests that fasting diets may help those with diabetes and cardiovascular disease, alongside established weight loss claims.

Intermittent fasting -fasting on a given number of consecutive or alternate days -- has recently been hailed as a path to weight loss and improved cardiovascular risk. A team led by James Brown from Aston University has evaluated the various approaches to intermittent fasting in the scientific literature. They searched specifically for advantages and limitations in treating obesity and type 2 diabetes using fasting diets.

The basic format of intermittent fasting is to alternate days eating 'normally' with days when calorie consumption is restricted. This can either be done on alternative days, or where two days each week are classed as 'fasting days'. These types of intermittent fasting have been shown in trials to be as effective as or more effective than counting calories every day to lose weight. Evidence from clinical trials shows that fasting can limit inflammation, improve levels of sugars and fats in circulation, and reduce blood pressure. Our fasting bodies change how they select which fuel to burn, improving metabolism and reducing oxidative stress.

For people with obesity, only one drug (orlistat) is currently available in the UK, and gastric surgery is a relatively rare and expensive alternative. Dietary changes remain the most common intervention used for obese people. Fasting is known to help, but former treatments were based on intermittent starving. Today's intermittent fasting regimes are easier to stick to, and are proven to help remove excess pounds melt away.

Scientists have known since the 1940s that intermittent fasting helps us lose weight, and can cut the incidence of diabetes in lab animals. Recent studies have also confirmed that restricting calorie intake could possibly reverse type 2 diabetes in some people. Researchers measured improved pancreatic function and fewer of the fatty deposits associated with insulin resistance were present in fasting subjects.

A healthy heart

In animal models, scientists have shown that intermittent fasting has some cardiovascular benefits that appear similar to exercising, such as improving blood pressure and heart rate, and lowering cholesterol. Fasting also appears to aid those with ischemic heart disease. Fasting may even protect the heart by raising levels of adiponectin, a protein that has several important roles in carbohydrate and lipid metabolism and vascular biology.

"Intermittent fasting might achieve much of the benefit seen with bariatric surgery, but without the costs, restriction on numbers and risks associated with surgery," according to lead author, James Brown. "Whether intermittent fasting can be used as a tool to prevent diabetes in those individuals at high risk or to prevent progression in those recently diagnosed with type 2 diabetes remains a tantalising notion and we are currently in preparation for clinical trials to assess the effectiveness of this form of lifestyle intervention in various patient groups."

Intermittent fasting is an increasingly popular diet plan that hit the headlines in the run up to Christmas 2012 after the release of a book on the subject. Proponents claim that in addition to weight loss, the diet can lead to longer life, and protection against disease, particularly conditions such as dementia and Alzheimer's disease.

UK terror plot leader jailed for minimum 18 years

LONDON (AP) ? The ringleader of an al-Qaida-inspired plot to detonate knapsack bombs in England was sentenced Friday to at least 18 years in jail.

Judge Richard Henriques said 31-year-old Irfan Naseer was "the leader, driving force and man in charge" of the elaborate plot, sentencing him to life with no possibility of parole for 18 years.

"Your plot had the blessing of al-Qaida and you intended to further the aims of al-Qaida," Henriques told Naseer in London as he sentenced the man nicknamed Big Irfan, or Chubbs, along with 10 accomplices. "Clearly nothing was going to stop you, short of intervention of the authorities."

Prosecutors had said the men, fired up by the sermons of U.S.-born al-Qaida preacher Anwar al-Awlaki, hoped to cause carnage on a mass scale. One of Naseer's accomplices was recorded calling the planned attack "another 9/11."

Police said the terrorist conspiracy was the most significant uncovered in Britain since a plot to blow up airliners in midair was foiled in 2006.

But the plot was undone by problems with money and logistics. No targets had been chosen and no bombs built when Naseer, Ashik Ali and Irfan Khalid, both now 28, were arrested in September 2011 in Birmingham, central England, after a huge investigation and surveillance operation by police and the security service.

Prosecutors said Naseer and Khalid had traveled to Pakistan for terror training, where they learned details of poisons, bomb-making and weaponry, and made "martyrdom videos" justifying their planned attacks.

On their return to England in July 2011, they began to recruit others to the plot and to raise money by posing as street collectors for Muslim charities. They also began experimenting with chemicals, the prosecution said, aided by Naseer's university degree in pharmacy.

But many of the group's plans soon went awry. Four other young men dispatched by the plotters to Pakistan for terrorist training were sent home within days when the family of one man found out. The four pleaded guilty to terrorism-related offenses.

Rahin Ahmed, an alleged co-conspirator described in court as the cell's "chief financier," tried to increase the group's budget by trading the money it made from bogus charity fundraising on the financial markets. Instead, he lost the bulk of the terror cell's money.

Among the pieces of evidence at the four-month trial was a sports injury cool pack, which prosecutors said Naseer had mistakenly believed would contain ammonium nitrate, a key bomb-making ingredient.

The group also considered other outlandish attacks, including tying sharp blades to the front of a truck and driving it into a crowd. Naseer was heard talking about the possibility of mixing poison into creams such as Vaseline or Nivea and smearing them on car handles to cause mass deaths.

Prosecutors said the men ultimately gravitated toward a plan to detonate up to eight knapsack bombs ? either on timers or in suicide attacks ? in a bid to cause destruction on a scale larger than the July 7, 2005, London transit bombings, which killed 52 commuters.

Naseer was recorded plotting about knapsack bombs going "boom, boom, boom everywhere," while Khalid said the attack would be "revenge for everything, what we're doing is another 9/11."

The trio was convicted in February of plotting terrorist attacks and sentenced Friday at Woolwich Crown Court, with Khalid getting a minimum of 12 years in prison and Ali a minimum of 10 years.

Eight others who had pleaded guilty to involvement also were sentenced.

Te'o time in San Diego; Geno Smith goes to Jets

NEW YORK (AP) ? Manti Te'o and Geno Smith provided the sizzle previously missing from the NFL draft.

Te'o is headed to San Diego, Smith is a Jet, and Radio City Music Hall shook with the kind of noise usually heard in stadiums when they were selected.

The theater rocked with two picks within minutes of each other Friday night.

Te'o, the Notre Dame All-America linebacker, was chosen sixth in the second round by the Chargers, drawing a loud roar from the fans. One spot later, the Jets took the West Virginia quarterback, drawing a raucous reaction of cheers and boos.

The big names had taken over from the bulk and beef of opening night, when 18 linemen went in the first round.

Te'o, who led the Fighting Irish to the national championship game, was projected as a first-rounder last year. But his poor performance in a rout at the hands of Alabama, some slow 40-yard dash times, and a tabloid-ready hoax involving a fake girlfriend that became a national soap opera dropped his stock.

"I did expect to go in the first round," Te'o said. "But things happened and all it did was give me more motivation."

When former Chargers defensive back Jim Hill was handed the card to make the announcement by Commissioner Roger Goodell, he was told, "You're going to get a big cheer when you announce this pick."

It was more a mix of surprise and recognition of the most talked-about player in the draft finally finding a landing spot at No. 38 overall.

The Chargers traded up with Arizona to grab Te'o, the Heisman Trophy runner-up. Te'o ran a 4.82-second 40-yard dash at the NFL combine, slow for a linebacker. He did better at Notre Dame's pro day, but NFL teams already had plenty of football reasons to doubt his worthiness as a first-round pick.

San Diego was willing to gamble on him.

"We did a lot of work on Te'o and I've seen him for a number of years," first-year general manager Tom Telesco said. "He loves football. He's passionate about it. He loves to practice. He loves to play."

Two officials, each with a different team, said their clubs passed on Te'o in the first round partly because of his off-field issues. The men, speaking on condition of anonymity because team draft strategy is confidential, said the decision was not just because of a disappointing combine performance or the linebacker's poor performance in the national title game.

Te'o was the third linebacker chosen in this draft.

"It's a perfect scenario. My parents can come and watch, I can go home, it's San Diego," said Te'o, a native of Hawaii. "We're all excited. I can't be any happier."

With the very next pick, the Jets sent their QB situation spiraling into further chaos. They already have Mark Sanchez, who struggled last season but was brought back in great part because of a prohibitive contract. They still have Tim Tebow, who almost certainly soon will be cut. They signed David Garrard, who hasn't played in the NFL since 2010.

And now there is Smith, who waited futilely throughout the first round, returned to the theater Friday and was rewarded.

"It's extremely relieving. I withstood the test of time," he said. "It felt like forever in there."

If Smith thought that was tough, wait until he enters the cauldron overseen by Jets coach Rex Ryan, where every move by every QB on the roster is tabloid-Internet fodder for days.

"I'm a competitor and I'm going to accept my role on the team, whatever is handed to me," Smith said, "but my job is to compete day in and day out."

Safety Johnathan Cyprien of Florida International was the first selection of the second round. Cyprien was a standout in the Sun Belt Conference and really solidified his stock with an excellent performance in the Senior Bowl.

"He's got a passion for the game," coach Gus Bradley said. "He is very animated. He just enjoys it. He loves to play the game. I think he's going to add to what we have here and the attitude that we're looking for."

Arizona added some spice to the third round by selecting former LSU cornerback-kick returner Tyrann Mathieu. The Honey Badger was a 2011 Heisman Trophy finalist that LSU dismissed from the team last August for failing a drug test. He was arrested in late October after police said they found marijuana at Mathieu's apartment.

"He impressed me so much in my office one on one, knowing at this point in time what he needs to do in his life," Cardinals first-year coach Bruce Arians said. "I was really taken aback a little bit. He knows what his problems are, he knows what he has done to himself, but he also knows that someone will give him a chance, that he knows what he needs to make sure he succeeds."

Other notable second-round picks Friday were Tennessee wide receiver Justin Hunter by the Titans, who traded up with San Francisco; Stanford All-America tight end Zach Ertz by Philadelphia; and North Carolina's Gio Bernard, the first running back chosen, by Cincinnati.

After no running backs were selected in the first round, five were taken in the second. The number of linemen dropped to five.

The presumed top-rated running back, Eddie Lacy of Alabama, went with the next-to-last selection of the round, to Green Bay.

NCAA record-setting RB Montee Ball of Wisconsin was chosen by Denver.

Tampa Bay's first pick this year was defensive back Johnthan Banks of Mississippi State at No. 43 overall. Washington, which traded it first-rounder last year to draft Robert Griffin III, went for defensive back David Amerson of North Carolina State at No. 51.

New England, known for trading early picks for a bunch of later selections, chose linebacker Jamie Collins of Southern Mississippi at No. 52. Seattle, after trading down six spots with Baltimore, closed out the second round by taking running back Christine Michael of Texas A&M.

Cleveland used its second-rounder, which would have been 39th overall, in last year's supplemental draft to take wide receiver Josh Gordon of Baylor, who made 50 catches for the Browns in 2012.

New Orleans was stripped of its second-round pick in the bounty scandal.

The final pick of Day 2 was the Titans' selection of Missouri linebacker Zaviar Gooden.

Among those who didn't go were quarterbacks Matt Barkley of Southern California, Landry Jones of Oklahoma and Ryan Nassib of Syracuse; South Carolina RB Marcus Lattimore, who is recovering from a severe knee injury; and two starters from national champion Alabama, OL Barrett Jones and DT Jesse Williams.

Red line: Obama cautious on Syria chemical weapons

WASHINGTON (AP) ? Proceeding cautiously, President Barack Obama insisted on Friday that any use of chemical weapons by Syria would change his "calculus" about U.S. military involvement in the 2-year-old civil war ? but said too little was known about a pair of likely sarin attacks to order aggressive action now.

The president's public response to the latest intelligence reflected the lack of agreement in Washington over whether to use America's military to intervene in the civil war, ? and if so, how. But lawmakers in both parties expressed concern that inaction could embolden Syrian President Bashar Assad and perhaps other countries including North Korea and Iran.

U.S. officials declared on Thursday that the Syrian government probably had used chemical weapons twice in March, newly provocative acts in the civil war that has killed more than 70,000 people and displaced hundreds of thousands more. The U.S. assessment followed similar conclusions from Britain, France, Israel and Qatar ? key allies eager for a more aggressive response to Syrian conflict.

Obama, in his first comments about the new intelligence disclosure, said Friday, "For the Syrian government to utilize chemical weapons on its people crosses a line that will change my calculus and how the United States approaches these issues." He has issued similar warnings for months, saying the use of chemical weapons or transfer of the stockpiles to terrorists would cross a "red line" and carry "enormous consequences."

Seeking to show resolve, Obama added Friday that "I've meant what I said."

The president is facing political pressure from a familiar contingent of senators, led by Arizona Republican John McCain, favoring a quick and strong U.S. response. But even those lawmakers appear opposed to an American military invasion and are instead supporting creation of a protective "no-fly zone" or another narrow, safe zone inside Syria, along its border with Turkey.

Some lawmakers voiced concern that if Obama doesn't make good on his promise to respond aggressively if it's shown that Assad used chemical weapons, his inaction could send a damaging message to the world.

"There's no question that when the United States takes a position that this crosses a line that our failure to respond has implications," said Rep. David Cicilline, a Democratic member of the House Foreign Affairs Committee. "So that if we, in fact, determine that chemical weapons were used, I think the expectation is that we and the coalition and others take some action."

Rep. John Mica, R-Fla., wondered whether the red line was "turning into a pink line."

White House officials insisted Obama's caution was not an indication that the line was shifting. Officials said firm evidence of a chemical weapons attack would trigger a U.S. response ? unspecified ? and would not be contingent on the size and scope of the use.

Obama met at the White House with Jordan's King Abdullah II, whose nation is suffering amid an influx of refugees spilling over its border with Syria. The president promised to vigorously pursue more information about chemical weapons attacks, including exactly who might be responsible and how they might have been carried out.

But the president set no deadline for answers.

"The president wants the facts," spokesman Jay Carney said. "And I'm not going to set a timeline because the facts need to be what drives this investigation, not a deadline."

Syrian officials denied Friday that their government forces had used chemical weapons against rebels.

Hanging over the Obama administration's approach to the new intelligence reports are hard lessons learned from the Iraq war, when faulty intelligence drew the U.S. into a lengthy and expensive conflict. Obama, as a candidate for U.S. Senate, opposed the Iraq war and made ending the conflict a priority in his first term.

Lawmakers on Capitol Hill appeared to be drawing on similar lessons from more than a decade ago. Many who sounded the alarm about Saddam Hussein and the possibility of weapons of mass destruction ? and strongly stood with President George W. Bush's decision to invade Iraq ? were far more muted on Friday.

Following a closed-door briefing by Secretary of State John Kerry, they stressed the importance of building international support for any military move against Syria rather than unilateral U.S. action. The sectarian strife in Iraq and the lawlessness in Libya after the killing of longtime leader Moammar Gadhafi in 2011 stand as sober reminders of what can happen.

"We want to do everything we can to avoid putting boots on the ground," said Rep. Dutch Ruppersberger of Maryland, the senior Democrat on the House intelligence committee. "I don't think that we, just as the United States, want to go in to another war."

Polling shows war-weary Americans are broadly opposed to the notion of the U.S. military intervening in Syria. Just one in five said the U.S. has a responsibility to do something about the fighting in Syria, according to a CBS News poll conducted in late March.

But faced with more specific scenarios, Americans appear more willing to back U.S. involvement. In an ABC News/Washington Post poll late last year, 63 percent said they would support military intervention if the Syrian government used chemical weapons against its people.

Roughly the same number said they would support using American military aircraft to create a no-fly zone if no ground troops were involved.

The White House faces a limited choice of military options to help the rebels oust Assad.

Arming the rebels would run into the reality that a military group fighting alongside them has pledged allegiance to al-Qaida. Establishing a no-fly zone poses a significant challenge, as Syria possesses an air defense system far more robust than the U.S. and its allies overwhelmed in Libya two years ago.

Thus far, the Obama administration has limited its assistance to the Syrian rebels to nonlethal aid, including military-style equipment such as body armor and night vision goggles. The U.S. has also deployed about 200 troops to Jordan to assist that country's military, and has participated in NATO's placement of Patriot missile batteries in Turkey near the border to protect against an attack from Syria.

Computer scientists suggest new spin on origins of evolvability: Competition to survive not necessary?

Apr. 26, 2013 ? Scientists have long observed that species seem to have become increasingly capable of evolving in response to changes in the environment. But computer science researchers now say that the popular explanation of competition to survive in nature may not actually be necessary for evolvability to increase.

In a paper published this week in PLOS ONE, the researchers report that evolvability can increase over generations regardless of whether species are competing for food, habitat or other factors.

Using a simulated model they designed to mimic how organisms evolve, the researchers saw increasing evolvability even without competitive pressure.

"The explanation is that evolvable organisms separate themselves naturally from less evolvable organisms over time simply by becoming increasingly diverse," said Kenneth O. Stanley, an associate professor at the College of Engineering and Computer Science at the University of Central Florida. He co-wrote the paper about the study along with lead author Joel Lehman, a post-doctoral researcher at the University of Texas at Austin.

The finding could have implications for the origins of evolvability in many species.

"When new species appear in the future, they are most likely descendants of those that were evolvable in the past," Lehman said. "The result is that evolvable species accumulate over time even without selective pressure."

During the simulations, the team's simulated organisms became more evolvable without any pressure from other organisms out-competing them. The simulations were based on a conceptual algorithm.

"The algorithms used for the simulations are abstractly based on how organisms are evolved, but not on any particular real-life organism," explained Lehman.

The team's hypothesis is unique and is in contrast to most popular theories for why evolvability increases.

"An important implication of this result is that traditional selective and adaptive explanations for phenomena such as increasing evolvability deserve more scrutiny and may turn out unnecessary in some cases," Stanley said.

Stanley is an associate professor at UCF. He has a bachelor's of science in engineering from the University of Pennsylvania and a doctorate in computer science from the University of Texas at Austin. He serves on the editorial boards of several journals. He has over 70 publications in competitive venues and has secured grants worth more than $1 million. His works in artificial intelligence and evolutionary computation have been cited more than 4,000 times.
