Why some people get zits and others don't

Feb. 28, 2013 ? The bacteria that cause acne live on everyone's skin, yet one in five people is lucky enough to develop only an occasional pimple over a lifetime. What's their secret?

In a boon for teenagers everywhere, a UCLA study conducted with researchers at Washington University in St. Louis and the Los Angeles Biomedical Research Institute has discovered that acne bacteria contain "bad" strains associated with pimples and "good" strains that may protect the skin.

The findings, published in the Feb. 28 edition of the Journal of Investigative Dermatology, could lead to a myriad of new therapies to prevent and treat the disfiguring skin disorder.

"We learned that not all acne bacteria trigger pimples ? one strain may actually help keep skin healthy," said lead author Huiying Li, an assistant professor of molecular and medical pharmacology at the David Geffen School of Medicine at UCLA. "We hope to apply our findings to develop new strategies that stop blemishes before they start, and enable dermatologists to customize treatment to each patient's unique cocktail of skin bacteria."

The scientists looked at a tiny microbe with a big name: Propionibacterium acnes, bacteria that thrive in the oily depths of our pores. When the bacteria aggravate the immune system, they cause the swollen, red bumps associated with acne.

Using over-the-counter pore-cleansing strips, LA BioMed and UCLA researchers lifted P. acnes bacteria from the noses of 49 pimply and 52 clear-skinned volunteers. After extracting the microbial DNA from the strips, Li's laboratory tracked a genetic marker to identify the bacterial strains in each volunteer's pores and recorded whether the person suffered from acne.

Next, Li's lab cultured the bacteria from the strips to isolate more than 1,000 strains. Washington University scientists sequenced the genomes of 66 of the P. acnes strains, enabling UCLA co-first author Shuta Tomida to zero in on genes unique to each strain.

"We were interested to learn that the bacterial strains looked very different when taken from diseased skin, compared to healthy skin," said co-author Dr. Noah Craft, a dermatologist and director of the Center for Immunotherapeutics Research at LA BioMed at Harbor?UCLA Medical Center. "Two unique strains of P. acnes appeared in one out of five volunteers with acne but rarely occurred in clear-skinned people."

The biggest discovery was still to come.

"We were extremely excited to uncover a third strain of P. acnes that's common in healthy skin yet rarely found when acne is present," said Li, who is also a member of UCLA's Crump Institute for Molecular Imaging. "We suspect that this strain contains a natural defense mechanism that enables it to recognize attackers and destroy them before they infect the bacterial cell."

Offering new hope to acne sufferers, the researchers believe that increasing the body's friendly strain of P. acnes through the use of a simple cream or lotion may help calm spotty complexions.

"This P. acnes strain may protect the skin, much like yogurt's live bacteria help defend the gut from harmful bugs," Li said. "Our next step will be to investigate whether a probiotic cream can block bad bacteria from invading the skin and prevent pimples before they start."

Additional studies will focus on exploring new drugs that kill bad strains of P. acnes while preserving the good ones; the use of viruses to kill acne-related bacteria; and a simple skin test to predict whether a person will develop aggressive acne in the future.

"Our research underscores the importance of strain-level analysis of the world of human microbes to define the role of bacteria in health and disease," said co-author George Weinstock, associate director of the Genome Institute and professor of genetics at Washington University in St. Louis. "This type of analysis has a much higher resolution than prior studies that relied on bacterial cultures or only made distinctions between bacterial species."

Acne affects 80 percent of Americans at some point in their lives, yet scientists know little about what causes the disorder and have made limited progress in developing new strategies for treating it. Dermatologists' arsenal of anti-acne tools ? benzoyl peroxide, antibiotics and Accutane (isotretinoin) ? hasn't expanded in decades. Most severe cases of acne don't respond to antibiotics, and Accutane can produce serious side effects.

The research was supported by a grant (UH2AR057503) from the National Institutes of Health's Human Microbiome Project through the National Institute of Arthritis and Musculoskeletal and Skin Diseases.

Big spending cuts mark tea party success, and risk

WASHINGTON (AP) ? The pending $85 billion in federal spending cuts would seem like a tea partyer's dream. Why, then, are tea party activists and other conservatives so wary on the eve of the big reductions, which Congress and the White House seem unable or unwilling to stop?

It's because even ardent cost-cutters see the so-called "sequester" as a ham-handed and unpredictable way to reduce federal spending. While a few tea party activists are claiming all-out victory, others are keeping their distance, calling the across-the-board cuts the least-bad of several unpleasant options.

"I think it's a crazy idea," said Sen. Marco Rubio, R-Fla., a tea party favorite. "The only thing crazier than sequester is to walk away from the cuts that it guarantees."

Rubio's remarks reflect Republicans' nervousness about how the public might react to the domestic and military spending cuts scheduled to begin Friday.

But in many ways, the sequester marks the tea party movement's maturation into a virtually mainstream role in the Republican Party. Cutting the Pentagon's budget once was unthinkable for most Republican lawmakers. But now it is trumped by the drive to keep taxes down while reducing costs wherever possible.

Congressional Democrats and Republicans agreed to the sequester in 2011 only as a consequence so unpalatable that it would goad them into finding a deficit-reduction compromise. The compromise never materialized, however, and now the nation is about to swallow what lawmakers once called a "poison pill" of their own making.

Republicans fear a possible backlash against program cuts and furloughs of government workers and contractors, especially at military bases. They also worry that the cuts will have an economic domino effect, eliminating thousands of private-sector jobs and possibly pushing the nation back into recession.

If that happens, and if voters decide Republicans are chiefly to blame, then the tea party movement could further divide an already roiling GOP.

President Barack Obama and other Democrats say Republican intransigence on tax increases is the sequester's main cause. And public polls indicate Americans are more inclined to fault the GOP if things go badly, although some Republicans believe they can change that.

For now, the approaching cuts are testament to the power of anti-tax sentiment ? and, to a less proven degree, anti-spending sentiment ? in the Republican Party. The tea party movement is strongly associated with these sentiments. But it certainly can't take all the credit.

Long before the tea party's birth in 2009, anti-tax activists such as Grover Norquist were pushing the Republican Party to take inviolable stands against new taxes, even as the deficit soared and the federal tax burden approached historic lows.

Obama won re-election after calling for new taxes on the wealthy. He achieved some of them in January. But Republican lawmakers now say "no more," contributing to the sequester impasse.

The tea party has lost much of its exotic flavor that was punctuated by noisy rallies with costumed activists in 2009 and 2010. Its influence, however, appears larger now. "It has melted into the GOP base," said John J. Pitney, Jr., a former Republican staffer who teaches political science at Claremont McKenna College in California. "Anti-tax voters make up a large share of the vote in GOP primaries," he said, "so Republican lawmakers support tax increases at their peril."

But Republicans could face another kind of peril, Pitney said, if the sequester lasts for months and begins to erode "visible, popular programs."

Duke University political scientist David Rohde said the tea party has become "the populist conservative faction of the Republican Party." It drew well-deserved credit for fueling the Republicans' big congressional and gubernatorial wins in 2010, he said, even though some tea party-backed Senate nominees lost key races.

The movement's future, Rohde said, depends on whether tea party activism is seen as helping or hurting Republican candidates in 2014 and beyond. Fallout from the sequester could play a big role in those elections.

Sen. Lindsey Graham of South Carolina is typical of Republican lawmakers who grudgingly accept the sequester and worry that tea party ideals can go too far.

"I believe that the cuts in defense are ill-conceived and will do a lot of damage," said Graham, whose state includes several military installations. "Some of these tea party folks don't mind losing their bases; others will."

The tea party drive to reduce federal spending at almost every level is potent in GOP circles. Rep. Jack Kingston of Georgia, eyeing a Senate race that will draw several hard-right Republican rivals, says the sequester appears inevitable, but it will extract an economic and political price.

Referring to military bases in his Savannah-based district, Kingston said, "my people will take it on the chin." But in constituent feedback about the sequester, he said, "the overwhelming number of people are saying, "Let it happen." They want to see that we are serious about cutting spending."

Even some tea party leaders say the movement's take-no-prisoners approach has its costs.

"Our brand is tarnished, but that's what happens when you get beat up," said Sal Russo, a founder of the California-based Tea Party Express. "It's not the brand" that counts, he said, "it's the ideas."

In the long run, Russo said, the benefits of reducing deficit spending will overshadow any short-term hits to the economy this year. If that happens, he said, the tea party's status will rise in the Republican Party and the nation at large.

The movement "is quite alive and well," he said.

But some question the tea party's willingness to embrace domestic and military cuts that don't touch the greatest causes of deficit spending: the popular but costly "entitlement" programs of Medicare, Medicaid and Social Security.

"They're amputating the wrong limb," said Rutgers University political scientist Ross Baker. If the tea party movement is to achieve its goal of undoing the government's borrowing habits, he said, it must prove it can blaze a political path to reductions in entitlement spending.

DEMOLITION DISASTER: Council Hears Concerns | WHOTV.com ...

The unexpected demolition of a historical house in Des Moines has produced some backlash, and moved the city council to look into changes, so it never happens again.

On February 14th, construction crews arrived at the property at 4111 Tonawanda drive. Less than 24 hours later. The home was destroyed. The reason so many are upset, is because it was a ?Lustron House.? It?s made out of prefabricated enamel steel, and was developed post-World War II, to help fill the need for housing for returning soldiers. Only 2,000 are left in the entire country, and about 150 are left in Iowa. The one in Des Moines was considered unique because of its large size, material it was made of, and the fact it had an indoor pool.

?There was never any mention of demolition. It was always assumed that it would stay there. Unfortunately that?s not the case but because planning and zoning did not make that a condition of the approval, legally the property owners had every right to demolish it,? explained Christine Hensley with the Des Moines City Council.

Sarah Oltrogge with the Des Moines Historical Society said they just wanted more time- at the very least to be able to study and document it further. So, to make sure something like this doesn?t happen to another historical building in Des Moines, Oltrogge has taken her concerns to the council.

?The City of Cedar Rapids has some wording in its municipal code about a moratorium of 10 business days, so that?s really what I would like this council to look at,? said Oltrogge.

The council voted to not only look into this option, but research other options by creating a task force made up of the mayor, a few council members, members of the public, and historical society members.

The attorney representing the new owners of the property in question said that ?failure to communicate? was the problem. He said no one contacted them to see if they had changed their mind about demolishing the house.

(AP) ? Dr. C. Everett Koop has long been regarded as the nation's doctor? even though it has been nearly a quarter-century since he was surgeon general.

Koop, who died Monday at his home in Hanover, N.H., at age 96, was by far the best known and most influential person to carry that title. Koop, a 6-foot-1 evangelical Presbyterian with a biblical prophet's beard, donned a public health uniform in the early 1980s and became an enduring, science-based national spokesman on health issues.

He served for eight years during the Reagan administration and was a breed apart from his political bosses. He thundered about the evils of tobacco companies during a multiyear campaign to drive down smoking rates, and he became the government's spokesman on AIDS when it was still considered a "gay disease" by much of the public.

"He really changed the national conversation, and he showed real courage in pursuing the duties of his job," said Chris Collins, a vice president of amfAR, the Foundation for AIDS Research.

Even before that, he had been a leading figure in medicine. He was one of the first U.S. doctors to specialize in pediatric surgery at a time when children with complicated conditions were often simply written off as untreatable. In the 1950s, he drew national headlines for innovative surgeries such as separating conjoined twins.

His medical heroics are well noted, but he may be better remembered for transforming from a pariah in the eyes of the public health community into a remarkable servant who elevated the influence of the surgeon general ? if only temporarily.

"He set the bar high for all who followed in his footsteps," said Dr. Richard Carmona, who served as surgeon general a decade later under President George W. Bush.

Koop's religious beliefs grew after the 1968 death of his son David in a mountain-climbing accident, and he became an outspoken opponent of abortion. His activism is what brought him to the attention of the administration of President Ronald Reagan, who decided to nominate him for surgeon general in 1981. Though once a position with real power, surgeon generals had been stripped of most of their responsibilities in the 1960s.

By the time Koop got the job, the position was kind of a glorified health educator.

But Koop ran with it. One of his early steps involved the admiral's uniform that is bestowed to the surgeon general but that Koop's predecessors had worn only on ceremonial occasions. In his first year in the post, Koop stopped wearing his trademark bowties and suit jackets and instead began wearing the uniform, seeing it as a way to raise the visual prestige of the office.

In those military suits, he surprised the officials who had appointed him by setting aside his religious beliefs and feelings about abortion and instead waging a series of science-based public health crusades.

He was arguably most effective on smoking. He issued a series of reports that detailed the dangers of tobacco smoke, and in speeches began calling for a smoke-free society by the year 2000. He didn't get his wish, but smoking rates did drop from 38 percent to 27 percent while he was in office ? a huge decline.

Koop led other groundbreaking initiatives, but perhaps none is better remembered than his work on AIDS.

The disease was first identified in 1981, before Koop was officially in office, and it changed U.S. society. It destroyed the body's immune system and led to ghastly death, but initially was identified in gay men, and many people thought of it as something most heterosexuals didn't have to worry about.

U.S. scientists worked hard to identify the virus and work on ways to fight it, but the government's health education and policy efforts moved far more slowly. Reagan for years was silent on the issue. Following mounting criticism, Reagan in 1986 asked Koop to prepare a report on AIDS for the American public.

His report, released later that year, stressed that AIDS was a threat to all Americans and called for wider use of condoms and more comprehensive sex education, as early as the third grade. He went on to speak frankly about AIDS in an HBO special and engineered the mailing of an educational pamphlet on AIDS to more than 100 million U.S. households in 1988.

Koop personally opposed homosexuality and believed sex should be saved for marriage. But he insisted that Americans, especially young people, must not die because they were deprived of explicit information about how HIV was transmitted.

Koop's speeches and empathetic approach made him a hero to a wide swath of America, including public health workers, gay activists and journalists. Some called him a "scientific Bruce Springsteen." AIDS activists chanted "Koop, Koop" at his appearances and booed other officials.

"I was walking down the street with him one time" about five years ago, recalled Dr. George Wohlreich, director of the College of Physicians of Philadelphia, a medical society with which Koop had longstanding ties. "People were yelling out, 'There goes Dr. Koop!' You'd have thought he was a rock star."

Koop angered conservatives by refusing to issue a report requested by the Reagan White House, saying he could not find enough scientific evidence to determine whether abortion has harmful psychological effects on women.

He got static from some staff at the White House for his actions, but Reagan himself never tried to silence Koop. At a congressional hearing in 2007, Koop spoke about political pressure on the surgeon general post. He said Reagan was pressed to fire him every day.

After his death was reported Monday, the tributes poured forth, including a statement from New York Mayor Michael Bloomberg, who has made smoking restrictions a hallmark of his tenure.

"The nation has lost a visionary public health leader today with the passing of former Surgeon General C. Everett Koop, who was born and raised in Brooklyn," Bloomberg said. "Outspoken on the dangers of smoking, his leadership led to stronger warning labels on cigarettes and increased awareness about second-hand smoke, creating an environment that helped millions of Americans to stop smoking ? and setting the stage for the dramatic changes in smoking laws that have occurred over the past decade."

Dr. Anthony Fauci of the National Institutes of Health taught Koop what was known about AIDS during quiet after-hours talks in the early 1980s and became a close friend.

"A less strong person would have bent under the pressure," Fauci said. "He was driven by what's the right thing to do."

Carmona, a surgeon general years later, said Koop was a mentor who preached the importance of staying true to the science in speeches and reports ? even when it made certain politicians uncomfortable.

"We remember him for the example he set for all of us," Carmona said.

Koop's nomination originally was met with staunch opposition. Women's groups and liberal politicians complained Reagan had selected him only because of his conservative views, especially his staunch opposition to abortion.

Foes noted that Koop traveled the country in 1979 and 1980 giving speeches that predicted a progression "from liberalized abortion to infanticide to passive euthanasia to active euthanasia, indeed to the very beginnings of the political climate that led to Auschwitz, Dachau and Belsen."

But Koop, a devout Presbyterian, was confirmed as surgeon general after he told a Senate panel he would not use the post to promote his religious ideology. He kept his word and eventually won wide respect with his blend of old-fashioned values, pragmatism and empathy.

Koop was modest about his accomplishments, saying before leaving office in 1989, "My only influence was through moral suasion."

The office declined after that. Few of his successors had his speaking ability or stage presence. Fewer still were able to secure the support of key political bosses and overcome the meddling of everyone else. The office gradually lost prestige and visibility, and now has come to a point where most people can't name the current surgeon general. (It's Dr. Regina Benjamin.)

Even after leaving office, Koop continued to promote public health causes, from preventing childhood accidents to better training for doctors.

"I will use the written word, the spoken word and whatever I can in the electronic media to deliver health messages to this country as long as people will listen," he promised.

In 1996, he rapped Republican presidential hopeful Bob Dole for suggesting that tobacco was not invariably addictive, saying Dole's comments "either exposed his abysmal lack of knowledge of nicotine addiction or his blind support of the tobacco industry."

He maintained his personal opposition to abortion. After he left office, he told medical students it violated their Hippocratic oath. In 2009, he wrote to Senate Majority Leader Harry Reid, urging that health care legislation include a provision to ensure doctors and medical students would not be forced to perform abortions. The letter briefly set off a security scare because it was hand delivered.

Koop served as chairman of the National Safe Kids Campaign and as an adviser to President Bill Clinton's health care reform plan.

Worried that medicine had lost old-fashioned caring and personal relationships between doctors and patients, Koop opened an institute at Dartmouth College in New Hampshire to teach medical students basic values and ethics. He also was a part-owner of a short-lived venture, drkoop.com, to provide consumer health care information via the Internet.

Koop was the only son of a Manhattan banker and the nephew of a doctor. He said by age 5 he knew he wanted to be a surgeon and at age 13 he practiced his skills on neighborhood cats. He attended Dartmouth, where he received the nickname Chick, short for "chicken Koop." It stuck for life.

He received his medical degree at Cornell Medical College, choosing pediatric surgery because so few surgeons practiced it. In 1938, he married Elizabeth Flanagan, the daughter of a Connecticut doctor. They had four children. Koop's wife died in 2007, and he married Cora Hogue in 2010.

He was appointed surgeon-in-chief at Children's Hospital in Philadelphia and served as a professor at the University of Pennsylvania School of Medicine. He pioneered surgery on newborns and successfully separated three sets of conjoined twins. He won national acclaim by reconstructing the chest of a baby born with the heart outside the body.

Although raised as a Baptist, he was drawn to a Presbyterian church near the hospital, where he developed an abiding faith. He began praying at the bedside of his young patients ? ignoring the snickers of some of his colleagues.

Four new species of water-gliding rove beetles discovered in Ningxia, China

Feb. 25, 2013 ? Four new species from the Steninae subfamily of the large family of rove beetles (Staphylinidae) have been discovered in the Ningxia Autonomous Region, China, as part of an exploration of the insect fauna of the Liupan Shan Natural Reserve, where a large number of specimens has been collected. The expedition also yielded 11 new records for the Ningxia province of previously described Steninae species. The study was published in the open access, peer reviewed journal Zookeys.

The Ningxia Autonomous Region is mainly known as a dry, desert-like land. The region of the Liupan Shan Natural Reserve, however, is part of the Liupan Shan mountains, also known as the green pearl on the Loess Plateau. The area is also regarded as a "Kingdom of Animals" for its great biological diversity.

The rove beetle family, Staphylinidae, is one of the most widely distributed beetle families in the world. However, the representatives of the Steninae subfamily are of particular interest. These fascinating beetles are known for their unique ability to glide on the surface of water.This special skill is made possible through evolutionary adjustment allowing the production of special gland secretions that reduce surface tension.

Out of the four newly described species two are from the genus Dianous, and as all representatives are experts in water gliding. The other two belong to the genus Stenus where this ability is only partly present. One of the species, Stenus liupanshanus lives in leaf litter and is therefore believed to not demonstrate the ability. However the other one, Stenus biwenxuani, was found on shore and is therefore considered to be a water glider.

Steninae are also specialist predators of small invertebrates such as collembola, which are frequently found in leaf litter. What is fascinating is the special hunting technique used by those beetles to catch their prey. Species in the genus Stenus can eject some of its mouth parts using blood pressure. The thin rod of the labium ends in a pair of pads with bristly hairs and hooks, called paraglossa, and between these hairs are small pores that exude an adhesive glue-like substance, which sticks to prey to secure a perfect catch and no escape.

Dr. Liang Tang from the Department of Biology, Shanghai Normal University, comments: "As far as the Steninae are concerned, Ningxia Autonomous Region is one of the most poorly explored regions, with merely two species being recorded until 2008. In the summer of 2008, a team surveyed the insect fauna of the Liupan Shan in southern Ningxia and collected a large number of Steninae. In this paper, we report the results of the study, which includes two new Stenus and two new Dianous species, and new province records for eleven Stenus species."

New device better traps viruses, airborne pathogens

Monday, February 25, 2013

Washington University engineering researchers have created a new type of air-cleaning technology that could better protect human lungs from allergens, airborne viruses and ultrafine particles in the air.

The device, known as the SXC ESP, was created by a team led by Pratim Biswas, PhD, the Lucy & Stanley Lopata Professor and chair of the Department of Energy, Environmental & Chemical Engineering in the School of Engineering & Applied Science.

A recent study of the device, published in Applied and Environmental Microbiology, found that it could help to prevent respiratory and viral infections and inhalation-induced allergic reactions more efficiently than existing filter-based systems.

Asthma, a chronic respiratory disease that can be triggered by inhaling allergens, pollen, pet dander and other particles, is one of the most costly health-care expenses in the United States at more than $50 billion.

"Because many people in developed countries spend the majority of time indoors, properly maintaining indoor air quality is an absolute necessity to protect public health," Biswas says.

The new device incorporates soft X-ray irradiation as a component of the electrostatic precipitation process currently used to remove large particles from airflows. By incorporating the soft X-ray enhanced electrostatic precipitation technology, the researchers were able to ensure very efficient charging of the particles over a broad range of sizes and their capture in the SXC ESP.

They exposed mice with compromised immune systems to the downstream air stream passing through the unit that contacted infectious viruses, allergens, anthrax, smallpox and other particles in the air. The sensitive mice survived, indicating that the SXC ESP was very effective in removing these biological agents from the air.

"Traditional air cleaners can trap viruses or other toxic particles in the filter, where they linger and grow," Biswas says. "This device finds the virus or toxic particle or bioterror agent and inactivates it in one application."

Ultimately, this technology could be incorporated into stand-alone air cleaners or scaled for use in aircraft cabins, offices and residential HVAC systems. It also could be used to clean up a diesel engine or power plant exhaust.

Michael Gidding, who is expected to graduate in 2013 with an MBA, a bachelor's in chemical engineering and a master's in energy, environmental and chemical engineering, and Daniel Garcia, a May 2012 chemical engineering graduate, have teamed up to scale up this technology for commercial use. Their startup, Aerosol Control Technologies (ACT), is based on the patented process Biswas developed.

There are many applications for the technology in the coal industry, Gidding says, from dust control and safety at the mine to flue-gas treatment at the power plant.

Gidding and Garcia are working on a prototype to be tested as a diesel particulate filter substitute.

US caught in awkward embrace of Myanmar 'crony'

YANGON, Myanmar (AP) ? The image was meant to convey growing friendship between the United States and Myanmar, the world's hottest frontier market. Flanked by national flags, Win Aung, the president of Myanmar's main business association, and U.S. Assistant Secretary of State Jose Fernandez shook hands in Yangon and agreed to deepen business ties between their countries.

The awkward part? The United States still dubs Win Aung a "crony" who allegedly used his close ties to Myanmar's old military rulers to build one of the country's biggest business conglomerates. He remains on a blacklist of entities U.S. citizens and companies are banned from doing business with.

Their handshake Monday illustrates the complex and sometimes contradictory path the U.S. is forging as it tries to encourage new business ties with Myanmar while retaining moral sway over powerful economic, political and military interests it has long censured. Many praise the ethical stance taken by U.S. policymakers and hope that the entry of U.S. companies will help forge a more transparent, less corrupt corporate culture. But some question the effectiveness of Washington's chosen tools and the impact they have on the ability of U.S. investors to compete in what has quickly become a hot market.

Unlike the European Union and Australia, which lifted their travel and financial sanctions against Myanmar, the United States has taken what U.S. officials call a "calibrated" approach to retain leverage in case Myanmar's political and economic reforms get derailed. While Washington has suspended most restrictions, the U.S. still maintains its list of targeted sanctions, bans some people from traveling to the U.S. and blocks imports of specific products, such as jade and rubies, for which trade has been dominated by state and military interests.

Fernandez was in Myanmar as part of a U.S. business delegation, the first since President Barack Obama's historic November visit. The delegation was organized by the U.S. Chamber of Commerce and hosted by Win Aung's group, the Union of Myanmar Federation of Chambers of Commerce & Industry. Over 50 representatives of U.S. companies including Chevron, General Motors, Target Corp., ConocoPhillips, Caterpillar, General Electric International, Honeywell and eBay are scheduled to spend the week meeting with leading businesspeople and government officials in Myanmar.

Fernandez, in an interview, declined to comment on Win Aung's inclusion in the list of so-called "Specially Designated Nationals." The list forms the backbone of U.S. sanctions against Myanmar now that general restrictions on investment, imports and financial services have been suspended in response to the sweeping economic and political reforms instated since Myanmar's president, Thein Sein, took office in March 2011.

Fernandez conceded that "maybe some adjustments need to be made" to the list, but praised it as an important foreign policy tool for encouraging responsible investment.

"The value of the list is we continue to have concerns about human rights abuses, as well as continued political prisoners, continued military ties to North Korea and corruption. That list is a valuable tool for addressing those concerns," he said.

Win Aung, who also heads the Dagon Group of Companies, with interests in timber, rubber, energy and construction, urged the United States to remove all its sanctions against Myanmar, also known as Burma.

"We request your government to support us with a total lifting of sanctions for the benefit of the majority of our people," Win Aung said.

U.S. companies have welcomed the easing of sanctions, but many say the fact that sanctions have been suspended, rather than eliminated, discourages long-term investment and that the welter of remaining regulations is a drain on time and resources.

"You can't do a lot of direct investment if there's the specter of it being taken away tomorrow," said Darren Brooks, senior corporate counsel for Caterpillar Asia. "It's a little bit of a minefield. We're trying to tiptoe around it and do things correctly."

The latest sign of the ambivalence of U.S. foreign policy came Friday, when the government responded to pressure from U.S. business groups by allowing U.S. companies to transact with four Myanmar banks that are still on the U.S. sanction list. Two of the banks, Myanma Economic Bank and Myanma Investment and Commercial Bank, are state owned. Asia Green Development Bank and Ayeyarwady Bank are privately owned.

Asia Green Development Bank is owned by Tay Za, who was described by the U.S. Treasury in 2008 as an arms dealer and financial henchman of the former military regime. Ayeyarwady Bank is owned by Zaw Zaw, who was described as "one of Burma's up-and-coming cronies" in a June 2009 leaked diplomatic cable from the U.S. Embassy in Yangon. He has not been publicly linked to arms or drug dealing.

"American corporations are very late in every business sector," said businessman Aung Aung, whose oil and gas and hotel companies have alliances with Korean, Indian and Russian partners. "Asian countries, like India and especially China, have already dominated the market. It's difficult for American companies to compete."

The U.S. ranked 13th in foreign investment in Myanmar as of Jan. 31, according to Myanmar's Directorate of Investment and Company Administration. The U.S. accounted for just 0.6 percent of approvals by dollar volume ? less than the Netherlands, France and Vietnam. China ranked number one with a 33.9 percent share of foreign investment approvals, followed by Thailand.

Sony Xperia Tablet Z is world?s thinnest tablet, goes underwater

Sony bills its new Xperia Tablet Z as the world?s thinnest tablet. And it?s beautiful. You can even get it wet. Unveiled at Mobile World Congress 2013, the Xperia Tablet Z is a slate you can use with confidence in the kitchen or by the pool. Those aren?t the only things Sony?s new device has going for it: A new SideView app lets you see what?s on TV and change the channel with a tap. Add in a full HD display with a wider color spectrum than the iPad and you have one of the more compelling Android tablets of the year.

MORE: See a video of Laptop's hands-on impressions of this bold new tablet.

For the Xperia Tablet Z, Sony ditched the fold design it used on its previous two Android tablets, the Sony Tablet S and the Sony Xperia Tablet S. That?s probably a good thing, for although we liked the distinctive shape of the latter, thin is in. The Tablet Z measures just 0.26 inches thick, making it the ?world?s thinnest 10-inch tablet,? according to Sony. Considering the Toshiba Excite 10 LE was 0.3 inches thick, we?re splitting hairs here, but the design is still remarkably svelte.

The Xperia Tablet Z weighs 1.09 pounds, making it lighter than competing devices such as the iPad (1.4 pounds) and the Excite 10 LE (1.13 pounds).

MORE: Top 10 tablets right now

According to Sony, the full HD (1920 x 1080) display on the Xperia Tablet Z has 20 percent great color gamut than the iPad, made possible by its Bravia engine. The 10.1-inch display has an aspect ratio of 16:10. During our hands-on time, images looked lush and vivid?even underwater.

Yes, the Tablet Z is IP57 water resistant, which means it can survive up to 30 minutes in 6 inches of water. We wouldn?t go swimming with it, but wouldn?t worry if someone accidentally spilled their Poland Spring bottle on the device, either. The screen can also be used even when covered with water, so you could use it in the shower, if you want.

Like the Xperia Tablet S, the Tablet Z has a built-in IR blaster. Used in conjunction with the Sony SideView app, which displays what programs are currently on TV, you can change to a desired show by merely flicking that program?s icon towards the top of the display. It?s a pretty neat feature, and one that Sony hopes will make its tablet more of a living-room staple.

The Tablet Z also has built-in NFC, as well as Sony?s One Touch technology. This lets you wirelessly connect to another NFC-enabled device, such as a speaker, merely by tapping it with the tablet. The onboard sound isn?t too shabby, either. Four speakers around the sides and back of the Tablet Z help ensure that sound doesn?t become muffled when the device is held or in someone?s lap.

MORE: 10 Tablets with the longest battery life

Inside the Tablet Z is a quad-core Snapdragon S4 processor. A battery stamina mode shuts down processes when the screen is off?but you can whitelist apps to remain on?so the tablet will have more than 4 times the standby time as the previous version. Sony estimates that the Tablet Z will last for about 8 hours while browsing the Web via Wi-Fi.

When it goes on sale in May, Sony will offer two versions of the Xperia Tablet Z: A 16GB model will cost $499, and a 32GB version will cost $599. The tablet will be available in white or black. Overall, the Xperia Tablet Z looks is a gorgeous and highly versatile tablet that?s tailor-made for TV fans.

Are Boomers Too Cautious About Stocks? | The Big Picture

Source: Squared Away Blog

?

The Financial Security Project (of Boston College) references the ongoing risk aversion that many investors still seem to laboring under.

They note:

Mutual fund investors poured some $17 billion into domestic equity funds in January, reversing 2012?s trend, according to the Investment Company Institute (ICI), an industry trade group.

But it?s too early to declare that fund investors have fully recovered from the 2008 market collapse, even as the bullish S&P500 stock market index flirts with its 1,565 all-time high reached on October 9, 2007.

This is something we see in the office all the time, and it is classified as a financial behavioral issue: Boomers have not not gotten back into equities, as they age they continually pare back their risk profiles.

I am not sure what the solution to the behavioral issue will be, but I suspect a lot of people who previously thought of themselves as ?comfortable? might be in danger of outliving their monies.

These are strange days . . .

Missouri Dems Propose Bill to Make it a Felony to Limit Union Power

Feb 23, 2013 Toro520

Via The Daily Caller:

Three Missouri Democrats signed on to a bill that would make it illegal for state legislators to even suggest laws limiting unions? collective bargaining powers.

The legislation was sponsored by Rep. Jeff Roorda. According to the text of the bill, any legislator who proposes restrictions on collective bargaining will be subject to prosecution for a class D felony.

?Any member of the general assembly who proposes a piece of legislation that further restricts the right of an individual to bargain collectively, as set forth under section 29, article I of the Missouri Constitution, shall be guilty of a class D felony,? reads the text of the bill.

The legislation would prevent state congressmen from proposing laws such as right-to-work, a popular labor policy reform that gives individual workers the right not to join unions. Michigan recently became the 24th?right-to-work state in the nation. Missouri does not have right-to-work.

Roorda?s office did not immediately respond to requests for comment. His bill likely came in response to one proposed by Republican Rep. Mike Leara, which would similarly criminalize any efforts by legislators to restrict gun ownership.

The Gulf of Mexico oil slick threatens disaster for the fragile US coast, causing clean-up efforts to focus on the best of a bad set of options: fight it there before it arrives here. An army of workers hired by British Petroleum, along with the US Coast Guard and local officials in Louisiana, have rushed to set out protective booms, spread dispersants and burn the oil when they can as it moves toward the shore. The strategy is to deal with the growing slick as much as possible before it laps into wetlands on Louisiana's coast, where its effects could be catastrophic and cleaning it is infinitely more difficult if not impossible.

The British energy giant now plans to load the 98-ton structure onto a boat at 'noon tomorrow' before shipping it out to the leak site. The dome, which is to be guided onto the largest of three oil leaks by remote-controlled submarines a mile down on the seabed, should be 'operational within six days,' Suttles said. Two weeks after the Deepwater Horizon rig exploded, the full impact of the disaster is being realized as a massive slick looms off the US Gulf coast, threatening to wipe out the livelihoods of shoreline communities.
