World's most extreme hearing animal: The greater wax moth

May 8, 2013 ? Researchers at the University of Strathclyde have discovered that the greater wax moth is capable of sensing sound frequencies of up to 300 kHz ? the highest recorded frequency sensitivity of any animal in the natural world.

Humans are only capable of hearing sounds of 20kHz maximum, dropping to around 12-15 kHz as we age, and even dolphins, known exponents of ultrasound, can?t compete as their limitations are around 160 kHz.

The research, conducted at the University?s Centre for Ultrasonic Engineering, has identified the extraordinary sensory characteristics of the moth, paving the way for developments in air-couple ultrasound.

Dr James Windmill, who has led the research at Strathclyde, said: ?We are extremely surprised to find that the moth is capable of hearing sound frequencies at this level and we hope to use the findings to better understand air-coupled ultrasound.?

?The use of ultrasound in air is extremely difficult as such high frequency signals are quickly weakened in air. Other animals such as bats are known to use ultrasound to communicate and now it is clear that moths are capable of even more advanced use of sound.

?It?s not entirely clear how the moths have developed to be able to hear at such a high frequency, but it is possible that they have had to improve the communication between each other to avoid capture from their natural predator ? the bat ? which use similar sounds.?

The research findings will allow the Dr Windmill and his colleagues to further develop their understanding of ultrasound and how to transmit and receive ultrasonic pulses travelling in air.

With frequency sensitivity that is unparalleled in the animal kingdom, this moth is ready for any echolocation call adaptations made by the bat in the on-going bat?moth evolutionary war.

Dr Windmill?s multi-disciplinary research team is now working to apply the biological study of this, and other insect ears to the design of micro-scale acoustic systems. It is hoped that by studying the unprecedented capabilities of the moth?s ear, the team can produce new technological innovations, such as miniature microphones.

(AP) ? North Korea on Tuesday threatened the United States and South Korea over joint naval drills taking place this week in tense Yellow Sea waters ahead of a Washington summit by the allies' leaders.

In a highly conditional warning, the section of the Korean People's Army responsible for operations in North Korea's southwest said it will hit back if any shells fall in its territory during the drills, which began Monday and will end Friday. Should the allies respond to that, the statement said, Pyongyang's military would then strike five South Korean islands that stand along the aquatic frontline between the countries.

The area includes waters that are claimed by both countries, and is the most likely scene of any future clash between the rival Koreas. North Korea disputes a boundary unilaterally drawn close to its shores by the U.S.-led U.N. Command after the war, and has had three bloody naval clashes with the South since 1999.

Highly critical language is standard from North Korea during what the allies call routine military drills that they stage over the course of a year. Tuesday's statement was softer than the bellicose rhetoric Pyongyang unleashed with regularity during two months of larger-scale joint military drills by the allies that ended one week ago. That included threats of nuclear and missile strikes on Washington and Seoul.

Still, this new warning comes at a time of tentative diplomatic maneuvering on the divided Korean Peninsula, which is still technically in a state of war, as the three-year Korean War ended 60 years ago in an armistice, not a peace treaty.

The threat also came hours ahead of a summit by U.S. President Barack Obama and South Korea's new president, Park Geun-hye. They hope to present a strong front against North Korea during their meeting Tuesday at the White House, but also want to leave the door open to talks with Pyongyang.

There are concerns that any skirmish or shelling between the Koreas could escalate into war. Two attacks blamed on Pyongyang in 2010 killed 50 South Koreans, and Park has repeatedly said Seoul would respond aggressively to another attack from the North.

If Pyongyang conducts an attack similar to the 2010 shelling of an island that killed four South Koreans, "We will make them pay," Park told CBS in an interview aired Monday.

Inter-Korean relations are particularly strained amid North Korean anger over U.S.-South Korean military drills and U.N. sanctions in March that sought to punish the North over its February nuclear test, the country's third.

Last week, South Korea pulled out its last remaining citizens from a joint factory park in North Korea after Pyongyang withdrew all of its 53,000 workers earlier. The park is the last symbol of inter-Korean rapprochement and an important source of hard currency.

North Korea suffered another financial blow Tuesday when one of China's biggest banks said it has halted business with a North Korean bank accused by the U.S. of financing Pyongyang's missile and nuclear programs in the latest sign of Beijing's anger with its estranged ally.

The state-run Bank of China Ltd. has notified the Foreign Trade Bank of North Korea that its account or accounts were being closed and all financial transactions suspended, said a bank spokeswoman, reading a brief statement. She did not provide further details.

The move comes after the Chinese leadership has shown growing frustration with North Korea's young leader Kim Jong Un and the nuclear and missile tests his government has conducted, aggravating regional tensions. China is North Korea's economic lifeline, providing nearly all of its fuel and most of its trade.

Despite the allies' claims that the military drills are routine, Pyongyang calls them invasion preparation and is especially sensitive to the inclusion of any U.S. nuclear-capable assets. Washington in March responded to rising tensions on the Korean Peninsula by making the unusual announcements that it had sent nuclear capable B-52 and B-2 bombers to participate in the drills, prompting a harsh North Korean rhetorical response.

Nuclear-powered U.S. carriers routinely come to South Korea around this time of year as part of drills aimed at enhancing naval cooperation, South Korean Defense Ministry spokesman Kim Min-seok said Monday in a briefing. But Seoul wouldn't discuss whether any U.S. nuclear capable assets were participating in this week's drills, and U.S. military officials declined to comment on operations.

On Tuesday, Kim denied North Korea's claim that South Korea's military this week conducted live-fire artillery drills near the disputed Yellow Sea waters.

Kim also said the South Korean military is keeping an eye on any movements of a North Korean mid-range missile on the east coast that's capable of potentially hitting Guam. South Korean officials said last month that the North was prepared to test the missile at any time.

Kim said Seoul would confirm if North Korea completely withdraws the missile, which officials earlier said the North seemed poised to test. He said he couldn't share any other details.

National study of nanomaterial toxicity sets stage for policies to address health risks

National study of nanomaterial toxicity sets stage for policies to address health risks [ Back to EurekAlert! ] Public release date: 6-May-2013

For the first time, researchers from institutions around the country have conducted an identical series of toxicology tests evaluating lung-related health impacts associated with widely used engineered nanomaterials (ENMs). The study provides comparable health risk data from multiple labs, which should help regulators develop policies to protect workers and consumers who come into contact with ENMs.

Researchers have done a great deal of toxicological research on ENMs over the past 10 years, but the results have often been difficult to interpret. This is because ENMs from different sources had different chemical and physical properties, and because investigators used different protocols to conduct the experiments.

"The goal of creating this multicenter consortium was to have multiple labs recreate key studies using the same materials and protocols, so that policy-makers have access to consistent, comparable results from multiple institutions," says Dr. James Bonner, an associate professor of environmental and molecular toxicology at NC State and lead author of a paper describing the work.

For this study, researchers from eight institutions used mouse and rat models to look at pulmonary health effects related to exposure to titanium dioxide nanoparticles and carbon nanotubes.

The researchers found that carbon nanotubes, which are used in everything from bicycle frames to high performance electronics, produced inflammation and inflammatory lesions in the lower portions of the lung. However, the researchers found that the nanotubes could be made less hazardous if treated to remove excess metal catalysts used in the manufacturing process or modified by adding carboxyl groups to the outer shell of the tubes to make them more easily dispersed in biological fluids.

The researchers also found that titanium dioxide nanoparticles also caused inflammation in the lower regions of the lung. Belt-shaped titanium nanoparticles caused more cellular damage in the lungs, and more pronounced lesions, than spherical nanoparticles.

"The findings are significant, but the real take-away message here is that the multicenter consortium concept works and that means this is a starting point for assessing nanomaterials using this approach," Bonner says. "I'm optimistic that this will serve as a blueprint for similar efforts, which will give regulators comparable data across institutions that will be easier for them to interpret."

Israel strikes Syria again, rocking Damascus

By Dominic Evans and Oliver Holmes

BEIRUT (Reuters) - Israel carried out its second air strike in days on Syria early on Sunday, a Western intelligence source said, in an attack that shook Damascus with a series of powerful blasts and drove columns of fire into the night sky.

Israel declined comment but Syria accused the Jewish state of striking a military facility just north of the capital - one which its jets had first targeted three months ago. Iran, a key ally of Syrian President Bashar al-Assad and an arch-enemy for Israel, urged states in the region to resist the Israeli attack.

People living near the Jamraya base spoke of explosions over several hours in various places near Damascus, including a town housing senior officials: "Night turned into day," one man said.

The Western intelligence source told Reuters the operation hit Iranian-supplied missiles headed for Lebanon's Hezbollah, a similar target to the two previous strikes this year, which have been defended as justifiable by Israel's ally the United States:

"In last night's attack, as in the previous one, what was attacked were stores of Fateh-110 missiles that were in transit from Iran to Hezbollah," the intelligence source said.

An Israeli official had confirmed a similar raid on Friday. In Lebanon, Hezbollah declined immediate comment.

Video footage uploaded onto the Internet by activists showed a series of explosions. One lit up the skyline of Damascus while another sent up a tower of flames and secondary blasts.

Syrian state media accused Israel of attacking in response to Assad's forces' recent successes against rebels who, with Western approval, have been trying to topple him for two years.

In 40 years since a war with a Syria then ruled by Assad's father, Israel has been locked in a cold standoff with Damascus, fought Hezbollah in Lebanon in 2006 and is threatening to attack Iran, accusing Tehran of trying to develop nuclear weapons.

But it is wary of instability in Syria, has long viewed Hezbollah as the more immediate threat and has shown little enthusiasm for U.S. and European calls for Assad's overthrow.

The raid follows intense debate in the United States over whether the use of chemical weapons by Syrian troops might push President Barack Obama to intervene more forcefully on the rebel side, but Western powers remain concerned at the presence of anti-Western Islamist fighters among Assad's opponents.

It was unclear whether Israel sought U.S. approval for the action; in the past, officials have indicated that Israel sees a need only to inform Washington once a mission was under way.

At a routine public appearance, Israeli Prime Minister Benjamin Netanyahu made no direct reference to the strikes but spoke pointedly of his responsibility to ensure Israel's future.

He maintained a plan to fly to China later in the day, suggesting a confidence that, as with the raid in January, Assad - and Hezbollah - would limit any reprisal. However, an Israeli military source said the army had deployed more anti-missile defense systems near the northern borders in recent days.

NIGHT OF EXPLOSIONS

"The sky was red all night. We didn't sleep a single second. The explosions started after midnight and continued through the night," one man told Reuters from Hameh, less than a mile from the Jamraya military research facility.

"There were explosions on all sides of my house," he added, saying people hid in basements during the events.

Another witness spoke of fire near Qura al-Assad, a town around 5 km (3 miles) west of Jamraya where many high-level government officials live. In the center of Damascus, people said their first thought was that there was an earthquake.

Identified by Syrian media as the Jamraya military research center, the target was also hit by Israel in another assault on January 30. Jamraya, on the northern approaches to Damascus, is just 15 km (10 miles) from the Lebanese border.

The British-based Syrian Observatory for Human Rights said the blasts hit Jamraya as well as a nearby ammunition depot.

Other activists said a missile brigade and two Republican Guard battalions may also have been targeted in the heavily militarized area just north of Damascus.

Reports by activists and state media are difficult to verify in Syria because of restrictions on journalists operating there.

People living in southern Lebanon said they heard frequent sounds of jets overhead and believed they were Israeli.

The streets of central Damascus were almost empty of pedestrians and traffic on Sunday morning, the start of the working week. Only a few shops were open. Checkpoints that have protected the government-controlled zone from rebel attack appeared to have been reinforced with additional men.

Syria's state television said the strikes were a response to recent military gains by Assad's forces against rebels: "The new Israeli attack is an attempt to raise the morale of the terrorist groups which have been reeling from strikes by our noble army," it said.

Speaking shortly before Sunday's attack, President Obama said Israel had a right to act: "The Israelis justifiably have to guard against the transfer of advanced weaponry to terrorist organizations like Hezbollah," he said.

In Israel, a military spokeswoman said of the attack in Syria: "We don't respond to this kind of report."

Netanyahu appeared at the dedication of a highway junction in memory of his late father. He made no reference to raids but said his father "taught me that the greatest responsibility we have is to ensure Israel's security and guarantee its future."

MISSILE "BETTER THAN SCUD"

Israel has repeatedly made clear it is prepared to use force to prevent advanced weapons from Syria reaching Hezbollah guerrillas, who fought a 34-day war with Israel seven years ago.

Uzi Rubin, an Israeli missile expert and former defense official said the Fateh-110 missile "is better than the Scud, it has a half-ton warhead". Iran has said it adapted the missile for anti-ship use by installing a guidance system, he added.

With Assad battling the revolt, Israelis also worry that Islamist rebels among the majority Sunni Muslim population could loot his arsenals and eventually hit the Jewish state, ending four decades of relative cross-border calm.

There was no immediate indication of how Syria would respond to Sunday's attack. After Israel's January raid, Damascus protested to the United Nations and the Syrian ambassador to Lebanon promised a "surprise decision", but no direct military retaliation followed.

Iranian Defense Minister Ahmad Vahidi was quoted by the ISNA news agency as saying on Sunday: "The Zionist regime's attack on Syria, which occurred with the U.S.'s green light, revealed the relationship between mercenary terrorists and their supporters and the regime occupying Jerusalem ... The evil actions of the Zionist regime can threaten the security of the entire region."

The uprising against Assad began with street protests that were met with force and grew into a bloody civil war in which the United Nations says at least 70,000 people have been killed.

Assad has lost control of large areas of north and eastern Syria, and is battling rebels on the fringes of Damascus.

But his forces have launched counter-offensives in recent weeks against the rebels around the capital and near the city of Homs, which links Damascus with the Mediterranean heartland of Assad's minority Alawites, who have religious ties to the Shi'ite form of Islam practiced in Iran.

Opposition activists said hundreds of Sunni families fled the coastal town of Banias on Saturday after fighters loyal to Assad killed at least 62 people and left bloodied and burned corpses piled in the streets. It was the second such alleged massacre in the area in the recent days.

The Kentucky Derby is known as much for hats and high fashion as it is for fast horses. This year, rains are swamping Churchill Downs, but fans on the infield are still holding their heads ? and their hats ? high.

Bigger and bolder is the rule for hats that often dwarf their owners.

Photosphere images can now be embedded via the web

360-degree panoramas from supported devices can now be included on websites, thanks to new Google widget

The ability to create 'Photosphere' 360-degree panoramas is one of the coolest features of the current crop of Nexus devices (and a few others running custom software). But so far the only place to share these images has been Google+ and a handful of other Google services, including Maps.

Today that changes, with the launch of new code widgets allowing Photosphere images to be embedded in the HTML of a standard web page. The results can be seen above -- that's a shot on the Las Vegas strip during CES 2013, taken on the Nexus 4.

The process isn't anywhere near as simple as a YouTube video embed. You'll need to know the exact URL of the image you want to use, as well as a bunch of other parameters calculated from metadata on Google's servers. So we're still a ways off a simple share button for Photosphere images, which is a shame.

Right it's still a very small minority of Android devices that has the ability to create these images, but regardless, this new code is an important step in opening up 'spheres to third-party sites.

More details and sample code can be found over at the source links.

Obama rounds out economic team with Commerce, trade picks

By Jeff Mason and Doug Palmer

WASHINGTON (Reuters) - President Barack Obama tapped Mike Froman and Penny Pritzker for the last two vacant Cabinet slots on his economic team on Thursday, turning to a law school classmate who is already one of his chief advisers and a billionaire businesswoman who helped put him in the White House.

As key members of his team, the two will work to boost demand for U.S. goods and workers, Obama said as he announced the nominations at the White House shortly before leaving on a trip to Mexico, a key U.S. trading partner.

He urged the Senate to quickly confirm the pair.

Froman, Obama's pick to be U.S. trade representative, is little known to the American public but a heavyweight in diplomatic circles for his role as the president's chief international economic affairs adviser, a post he has held since Obama took office in 2009.

Pritzker, tapped to become the U.S. Commerce secretary, is an heir to the Hyatt Hotel fortune and was finance chairman for Obama's 2008 presidential campaign. She is ranked 271st on Forbes Magazine's list of the wealthiest Americans and eighth on Chicago Magazine's list of the city's most powerful people.

If confirmed, as expected, Froman would succeed former Dallas Mayor Ron Kirk as the top U.S. negotiator on international trade. Kirk left the administration in March.

Senator Max Baucus, the Montana Democrat who chairs the Senate Finance Committee which will consider the nomination, said Obama's choice of Froman shows "the administration is sending a clear signal that trade is a top priority."

Some key Republicans in the House of Representatives also voiced support for Froman, but Senator Orrin Hatch, the top Republican on the finance panel, was more circumspect.

"I look forward to fully examining Mr. Froman's background and qualifications as the nomination moves forward," he said.

Pritzker would replace acting Commerce Secretary Rebecca Blank, who is leaving the government in July. As the head of the Commerce Department, she would serve in effect as an ambassador to the U.S. business community.

After winning re-election in November, Obama replaced several members of his economic and national security policy team. He tapped White House budget director Jack Lew to replace Timothy Geithner at the Treasury Department and put new leaders at the State Department, Pentagon and CIA.

'OPPORTUNITIES AND CHALLENGES'

Both of the nominees announced on Thursday have long ties to Obama, in Froman's case going back to the days when they were editors on the Harvard Law Review. Pritzker met Michelle and Barack Obama in the late 1990s, when she took her children to a basketball clinic run by the Michelle's brother, Craig Robinson.

Froman would take the reins at USTR in time to potentially oversee the completion of a landmark free trade agreement, the proposed Trans-Pacific Partnership among 12 countries in the Asia-Pacific region.

Those talks, which have recently been expanded to include Japan, are slated to conclude this year.

But tough decisions on issues including rules for state-owned enterprises, protections for workers rights and the environment, and phasing out tariffs on sensitive agricultural and manufacturing products could push the talks into 2014.

The United States and the 27 countries of the European Union are also preparing to launch talks on the proposed Transatlantic Trade and Investment Partnership, a free trade pact covering more than half of world economic output.

"The new USTR has both enormous opportunities and enormous challenges that have be reckoned with," said Charlene Barshefsky, who held the post in the late 1990s under former President Bill Clinton.

In addition to forging the regional trade pacts, the United States needs to confront threats to its competitive advantage from other countries that are stealing its intellectual property and valuable corporate trade secrets, she said.

During his confirmation hearing, Froman is likely to face questions on how forcefully Obama will push for "trade promotion authority." That legislation, also known as "fast track," allows the White House to submit trade agreements to Congress for straight up-or-down votes without any amendments.

The trade law tends to divide Democrats in Congress between those who see trade agreements as an engine for economic growth and those who blame them for manufacturing job losses.

Congress last passed a trade promotion authority bill in 2002 after a bitter fight in the House of Representatives.

OBAMA FUNDRAISER

Pritzker, a Stanford University-trained lawyer, would bring a member of one of the country's most successful business families to the helm of the Commerce Department.

The department has played a key role in Obama's five-year goal of doubling exports to about $3 trillion by the end of 2014. But after fast export growth in 2010 and 2011, the pace faltered in 2012, raising doubt the goal can be reached.

Pritzker would also be in charge of a diverse array of agencies, including the Census Bureau, the U.S. Patent and Trademark Office and the National Oceanic and Atmospheric Administration.

Pritzker is on the board of the Hyatt Hotel Corp, which her uncle founded in 1957 two years before she was born. She also has pursued a separate career in real estate and investment as founder and chairman of PSP Capital Partners and its affiliate, Pritzker Realty Group.

When she was finance chairman for the Obama campaign in 2008, she oversaw the raising of nearly $750 million, a record-breaker.

Pritzker could face questions over her family's reputation for sheltering income to avoid taxes, Hyatt's battle with the Unite Here labor union and the 2001 failure of Superior Bank, which was half-owned by the Pritzker family.

Unite Here has organized a boycott of Hyatt, which it calls "the worst hotel employer in America" because of the company's treatment of workers, failure to reach a new labor contract covering thousands of its employees and opposition to allowing workers at additional Hyatt hotels into the union.

During the 2008 presidential campaign, Republicans tried to tar Pritzker with the failure of Superior Bank, which in the 1990s was a pioneer in subprime mortgages, the type of loans that were blamed for the global financial crisis a decade later.

Regulators closed the bank in July 2001 after auditors concluded that income from mortgage securitizations had been overstated. Five months later, the Pritzkers agreed to pay the Federal Deposit Insurance Corporation $460 million over 15 years as part of a deal where the family and the other half-owner admitted no liability.
