ORLANDO | Fri Sep 27, 2013 12:13pm EDT

ORLANDO (Reuters) - Scientists trying to understand why destructive wood-eating termites are so resistant to efforts to exterminate them have come up with an unusually repugnant explanation.

Termites' practice of building nests out of their own feces creates a scatological force field that Florida scientists now believe is the reason biological controls have failed to stop their pestilential march all over the world.

A nine-year study concluded that termite feces act as a natural antibiotic, growing good bacteria in the subterranean nests that attack otherwise deadly pathogens, according to the findings published this month in the Proceedings of the Royal Society B.

"When they make a poop, it's not like they can throw it away and say forget about this. And over the millions of years of evolution it somehow evolved to take advantage of the poop there," said Nan-Yao Su, a University of Florida entomology professor and lead scientist and co-author of the study, along with Thomas Chouvenc, a University of Florida research associate.

Su also is the inventor of the popular Sentricon termite baiting and control system, which in 1995 became the first major alternative to liquid chemical treatments.

The findings could put an end to 50 years of failed research attempts to find a species of fungi that could kill termites when introduced into nests. Research repeatedly showed that fungi killed termites in a petri dish but not in the wild, Su said.

"Nobody was able to make it work in the field, but nobody would admit it," he said.

Su's goal was to find out why biological control never worked. His research colleagues determined that Streptomyces bacteria that are found in the nests and feed on fecal matter may be producing beneficial antimicrobial compounds that protect the termites from other potentially toxic matter.

Termites, mostly the voracious Formosans, cause $40 billion worth of damage a year worldwide, eating through wood structures particularly in Japan, China and the United States, Su said.

By the time a house is infested, the underground termite nest typically is 300 feet in diameter, hosting several million termites with a biomass weight of approximately 30 pounds, the weight of a medium-sized dog.

In one example, termites took nine months to bring down a new house in Hawaii built in the 1970s inadvertently on top of an untreated termite colony, Su said.

Further research will attempt to discover a way to bypass the protective compounds to destroy the termites, and to determine whether the findings can lead to new antibiotics for humans to replace those which have become ineffective.

BEIJING | Fri Sep 27, 2013 7:18am EDT

BEIJING (Reuters) - A Chinese viewing tower in the shape of a giant, copper puffer fish has raised an online huff about the latest in a series of bizarre and extravagant targets of state investment.

Encased in 8,920 copper plates and built at a cost of around 70 million yuan ($11.4 million), the tower on an island in Yangzhong county, eastern Jiangsu province, hovers 15 storeys above ground.

The government has often been criticized for wasteful investment to power the world's No. 2 economy. Beijing acknowledges the problem and wants consumption to overtake investment as a driver of growth.

Residents who welcome the fish tower say it improves the county's image. Less enthusiastic residents question whether such expensive and impractical buildings are needed.

"To spend so much money on something so meaningless, I really admire these 'wealthy' people," Mother988 said on Sina Weibo, China's version of Twitter, with apparent heavy irony.

The People's Daily, the Chinese government's main mouthpiece, acknowledged that the construction had polarized opinion.

"Once this giant puffer made its appearance, it caused a heated debate online," it said.

Public records show Jiangsu's local government bodies are the most indebted in the country.

Jiangsu says its debt is manageable, but took steps this week to rein in risk by announcing plans to control land sales, becoming the first Chinese government to do so.

Yangzhong aims to promote the tower as the world's biggest metal construction in terms of volume, the People's Daily said.

Central Henan province drew controversy in 2011 when a state-backed charity tried to build an eight-storey sculpture of Song Qingling, second wife of modern China's founding father Sun Yat Sen. Construction was scrapped half-way through.

The eastern province of Zhejiang also came under the spotlight after it modeled one of its city court houses on Capitol Hill.($1 = 6.1 yuan)

Half of British pilots admit to falling asleep in cockpit - survey
Sep 27th 2013, 12:33

By Sarah Young

LONDON | Fri Sep 27, 2013 8:33am EDT

LONDON (Reuters) - More than half of British airline pilots say they have fallen asleep in the cockpit, a survey said, ahead of an EU vote on flying hours which a pilots' association said could compromise flight safety.

According to the British Airline Pilots' Association (BALPA), 56 percent of 500 commercial pilots admitted to being asleep while on the flight deck and, of those, nearly one in three said they had woken up to find their co-pilot also asleep.

Pilot exhaustion grabbed the headlines this week when a newspaper reported two pilots on a British long-haul flight fell asleep in the cockpit, leaving the packed jet travelling unsupervised on autopilot.

The survey, released by BALPA, came ahead of a vote in the European Parliament on Monday on new rules which could replace British regulations.

BALPA, a trade union for pilots, voiced concerns that these proposed changes would water down British safety standards.

The rule changes would mean that pilots could work a maximum of 110 hours in a two-week period, more than the 95-hour limit under British regulations, and at night could be expected to fly for up to 11 hours, against a current 10-hour limit.

"Tiredness is already a major challenge for pilots who are deeply concerned that unscientific new EU rules will cut UK standards and lead to increased levels of tiredness, which has been shown to be a major contributory factor in air accidents," BALPA General Secretary Jim McAuslan said in a statement.

The proposals, devised by the European Aviation Safety Agency to harmonize the rules regarding pilots' hours across the European Union, would also mean they could be called to work at any time on their days off. Currently, restrictions are in place to help them plan their rest on days off.

The survey of pilots, by pollster ComRes, found 84 percent of respondents believed their abilities had been compromised over the last six months by tiredness with almost half saying pilot exhaustion was the biggest threat to flight safety.

British lawmakers, in a report published earlier this month, expressed concern that the new European rules set the limit for the flight duty period at night too high.

But the Association of European Airlines, which represents 31 European airlines, urged support for the proposals, saying they would ensure all airlines followed the same rules.

"The new ... rules would ensure that Europe will continue to have one of the strictest rules in the world, even stricter than today," the body's acting Secretary-General Athar Husain Khan said in a statement.

The Civil Aviation Agency, Britain's aviation regulator, dismissed worries about the new rules.

"We think the new European flight time limitation regulations maintain the UK's current high safety levels, and will actually increase safety for UK passengers travelling on some other European airlines," it said in a statement.

Pilots fall asleep on long-haul flight to UK: paper
Sep 26th 2013, 18:50

LONDON | Thu Sep 26, 2013 2:50pm EDT

LONDON (Reuters) - Two pilots on a British airliner on a long haul flight fell asleep in the cockpit, leaving the packed jet travelling unsupervised on autopilot, Britain's Sun newspaper reported on Thursday.

One of the pilots on board the Airbus 330 flight to Britain - the name of the airline was not disclosed - eventually woke up and roused his colleague, but neither knew how long they had been asleep, the paper said.

The flight took off on August 13 and the pilot and co-pilot took turns to have 20-minute rests but, after flying for more than an hour, they both dropped off.

They reported the incident themselves to Britain's Civil Aviation Authority (CAA), blaming longer shifts during the summer holiday period. The Sun said it had seen a copy of their report.

The CAA said it was legally prevented from disclosing any details about companies or individuals who filed Mandatory Occurrence Reports to them.

"Fatigue is a serious issue and needs careful oversight, which is why we welcome new EU proposals to give regulators greater powers to oversee airlines' fatigue risk management systems and data," a CAA spokesman said.

"The UK has an excellent safety record, but we are constantly striving to improve air safety."

Termites' powerful weapon against extermination? Their own poop

IRS rides 1884 'dead horse' law to defense of tax preparer rules
Sep 24th 2013, 21:16

By Patrick Temple-West

WASHINGTON | Tue Sep 24, 2013 5:16pm EDT

WASHINGTON (Reuters) - The Obama administration on Tuesday defended its effort to regulate the tax return preparation business for the first time in U.S. history, basing its case largely on a 19th century law dealing with horses lost or killed in the Civil War.

At an appellate court hearing on a challenge brought by libertarian lawyers challenging the administration, Justice Department Tax Division lawyer Gilbert Rothenberg said: "I hate to beat a dead horse, especially one from the Civil War era."

But he explained that the administration sees the "Horse Act of 1884" as providing ample authority for the U.S. Internal Revenue Service to regulate the tens of thousands of preparers who fill out millions of Americans' federal tax returns.

A three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit heard the administration's argument. Rothenberg said the IRS should be allowed to force tax return preparers - who are now unregulated - to pass a competency test and take annual continuing education classes.

But the Institute for Justice, a libertarian advocacy law firm, disagreed.

"Congress never gave the IRS authority to regulate tax preparers," said Dan Alban, an attorney for the institute.

The case has broad implications for the industry, which includes H&R Block Inc, a few mid-tier companies and thousands of tiny, mom-and-pop firms.

A decision from the judges is still months away. In oral arguments, the judges - all appointed by Republican presidents - gave no clear sign of how they will rule, yea or neigh.

But they did question why the IRS was citing an 1884 law to justify trying to police tax return preparers in 2013.

LEGAL REPRESENTATION AT ISSUE

After the Civil War, many Americans brought war loss claims against the U.S. government, often for dead or missing horses.

A post-war industry emerged of agents who would press war loss claims for a fee, usually a percentage of the claim collected. Soon, claim values were being fraudulently inflated.

In response, the government started regulating these intermediaries, barring unscrupulous ones and certifying honest ones as "enrolled agents," a title that is still used today by people who represent clients in matters before the IRS.

The IRS is arguing that tax return preparers represent their customers in much the same way that enrolled agents do, so the agency should be able to expand regulation to include preparers.

But the Institute for Justice is arguing that tax return preparers do not carry out the same level of representation, but rather merely provide a paid service for clients.

"Preparing a tax return is not a representative act," Alban said. "It is performing a service, certainly, but there's no representation."

More than 78 million Americans in 2011 paid someone to prepare their tax returns. The industry posted estimated revenue this year of $9.4 billion.

The Institute sued in March 2012 to block the IRS's regulations and won a district court ruling in January halting parts of the agency's program. The IRS appealed.

KOCHS HELPED FUND CHALLENGER

Based in Arlington, Va., the institute litigates over issues such as private school vouchers and eminent domain. It was begun in 1991 with funding from wealthy industrialists and conservative activists David and Charles Koch.

Sabina Loving, a Chicago tax preparer, is the lead plaintiff in the case. She was not present at the oral arguments.

Some of the tax experts who attended said the judges seemed skeptical of the IRS's argument. "Clearly, they were leaning toward Loving," said Don Williamson, a tax accountant and executive director of American University's Kogod Tax Center.

"It looks like a good day for Mr. Alban," said Robert Kerr, senior director of government relations for the National Association of Enrolled Agents, a tax-preparers trade group.

Kathryn Keneally, head of the Justice Department tax division, declined to comment on the oral arguments while leaving the court room.

The case is Sabina Loving et al v. Internal Revenue Service, U.S. Court of Appeals for the District of Columbia Circuit, No. 13-5061.

Wild pigs menace suburban Atlanta
Sep 24th 2013, 21:55

By David Beasley

ATLANTA | Tue Sep 24, 2013 5:55pm EDT

ATLANTA (Reuters) - Wild pigs have descended on a suburban Atlanta neighborhood where they are scaring children, making a general nuisance of themselves, and acting as they if they own the place.

One large specimen was sighted on Monday morning rummaging through garbage it had strewn across Taneisha Danner's front yard in Lithonia, an area about 19 miles east of downtown Atlanta.

It then trotted into the backyard, taking a nap before returning with three other pigs from a patch of nearby woods, Danner told Reuters on Tuesday.

"This is their home," Danner joked. "We're just visiting."

She said the animals were no laughing matter for neighborhood children, however, noting that some were now afraid to leave the safety of their homes.

"My children are even afraid to be downstairs, worried that he (the pig) could come through the door," Danner said.

Descendents of wild boar, the feral pigs are a particular pest in rural Georgia and notorious for damaging farmer's crops, said Charlie Killmaster, a deer and feral hog biologist with the Georgia Department of Natural Resources.

There are so many hogs that hunting season has been flung wide open for wild pigs on private land, he said, adding that it was still fairly rare for them to show up in suburban neighborhoods.

The population of one of the most invasive and destructive wild animals in the United States has grown rapidly in recent years, however. What was once a largely rural problem has blighted suburban areas in other states as well.

The hogs can be dangerous to humans if they are cornered or if their young are threatened, Killmaster said.

"There is some level of danger associated with them," he added. "But in nearly all cases, steering clear of them is all you need to do."

Danner said she had complained to local authorities about the hogs and was told they were trying to find a private trapper to remove them.
