Stanford economists talk tax reform

shutterstock.com/PTstock

Experts on the U.S. tax code from within the Stanford community will be among those attending an economic summit in March hosted by SIEPR.

It's that time of year again when the shades come up at the local H&R Block and it seems like TurboTax has bought ad space on every website.

But while many of us are most immediately concerned with April 15, and whether refunds are coming our way, this annual accounting of income earned, spent and stashed away leads some to discuss the tax code itself.

"You can't really think about taxes unless you think about the overall budgets, spending, the relationship of the federal, state and local governments, where those things are headed and things of that sort," said Michael Boskin, a Stanford professor of economics.

Boskin joined Stanford Professors John Shoven, Joseph Bankman and Lawrence Goulder and other top tax experts at a recent conference at the university on tax policy.

They discussed personal and corporate taxes as well as alternative taxes. Videos of their remarks are posted online.

The conference, co-hosted by the Stanford Institute for Economic Policy Research and the Tax Policy Center, a Washington, D.C.-based nonpartisan research center, highlighted research on the income gap, loopholes, international taxes, the federal deficit, entitlement programs and other issues.

Regarding projections of the growing debt and the political debates in Washington, Boskin, a senior fellow at SIEPR, said, "If something isn't done, we're heading into levels associated with, at best, stagnation and, at worst, financial chaos."

Goulder, an expert on environmental taxes and their effect on the economy, said the idea of a carbon tax to help repair the economy is gaining more traction among policymakers but "I think it's still a long shot."

"One of the things that got people's attention is that the carbon tax could be a way of helping finance tax reform and/or reduce the deficit," said Goulder, a senior SIEPR fellow.

SIEPR will be hosting a summit on the economy in March that will bring together leading experts in capital markets, the global economy, health care and tax reform.

Swiss Scientists Discover Dung Beetles Use The Milky Way For GPS

A team of Swedish scientists has discovered that dung beetles climb on dung balls and dance around in circles before taking off. This dance is not one of joy, however ? the insects are checking out the sky to get their bearings. Melissa Block and Audie Cornish have more.

MELISSA BLOCK, HOST:

From NPR News, this is ALL THINGS CONSIDERED. I'm Melissa Block.

AUDIE CORNISH, HOST:

And I'm Audie Cornish. And we have a story now about celestial navigation - that is, looking to the sky for guidance.

BLOCK: But before we get too lofty, this story also happens to be about dung beetles. And so we start with this lowly central unpleasant fact about dung beetles.

ERIC WARRANT: Dung beetles and their grubs eat dung and everything about dung beetles has to do with dung in some form.

BLOCK: That's professor Eric Warrant. He's an Australian professor of zoology teaching at the University of Lund in Sweden.

CORNISH: Five years ago, he and a group of other scientists began studying the remarkable navigational skills of dung beetles. These insects harvest material from a fresh pile of feces in the desert. They shape their bounty into a sphere and roll it away.

WARRANT: They have to get away from the pile of dung as fast as they can and as efficiently as they can because the dung pile is a very, very competitive place with lots and lots of beetles all competing for the same dung. And there's very many lazy beetles that are just waiting around to steal the balls of other industrious beetles and often there are big fights in the dung piles.

BLOCK: That's right - lazy dung beetles. Now, the dung beetles need to plot a direct course or they might accidentally circle back and thus lose a precious dung ball to another beetle.

WARRANT: It's a little bit like kicking the ball back into your own goal posts.

BLOCK: Which means no food to feed the next generation. As you can see, there's a lot riding on the beetles making a beeline to the place they hope to roll their ball.

CORNISH: Beeline it, wrong bug, I think.

BLOCK: Yeah, maybe a beetle line. Anyway, professor Eric Warrant and his colleague have just published conclusion about how the dung beetles keep to a straight path.

WARRANT: What we discovered was that dung beetles can roll their balls of dung in straight lines by using the Milky Way as a compass queue.

BLOCK: The Milky Way, billions of stars that form a white streak across the sky, serve as a guide for these little harvesters of waste. It was understood earlier that both the sun and the moon serve as guides, but no one knew how dung beetles could follow a straight path when the moon isn't out. So at the edge of the Kalahari, professor Warrant and the team built a small arena.

WARRANT: We tested them with and without a little cardboard hat, which we put on top of their head with a piece of tape. And this little cardboard hat effectively blocked out the view of the starry sky. And when we did this, they rolled around and around and around in circles. They couldn't keep a straight path.

BLOCK: The Swedish scientists also tested dung beetles at a planetarium. They altered the star pattern on the ceiling and watched what the beetles did. Without the Milky Way, the beetles could not walk the straight and narrow.

CORNISH: Professor Warrant suspects other creatures also navigate using the Milky Way, but currently only dung beetles are known to do so.

Secret prison camps revealed in new North Korea map

North Korea maps

Search for "North Korea" in Google Maps, and you'll get a whole new perspective.

Citizen cartographers and others have helped label landmarks in that enigmatic and repressive state, and Google pushed the results late Monday. Charting North Korea using its Map Maker software was a four-year process, David Marx, head of product PR for Google Asia-Pacific, tells Yahoo News.

The vetting process for a nation once labeled part of an "axis of evil" isn't much different from other countries: To guard against misleading information, users have to be signed into their Google accounts to contribute and are reviewed by fellow mapping volunteers. "However, we do also have a small team of reviewers across the globe that may review and moderate updates in Map Maker to ensure data quality," Marx added.

"We know this map is not perfect," wrote senior product manager Jayanth Mysore in the company blog Google Lat Long. "While many people around the globe are fascinated with North Korea, these maps are especially important for the citizens of South Korea who have ancestral connections or still have family living there."

Related: Google Unveiled Detailed Map of N. Korea

The use of North Korean satellite maps, however, has been geared less to matters of kinship and more about its human rights abuses and nuclear armament. DPRK Digital Atlas?based on Google Earth?recently debuted a detailed satellite overview of North Korea. The project, based out of the U.S.-Korea Institute at John Hopkins School of Advanced International studies (SAIS), emerged as a partnership with 38 North and North Korean Economy Watch (NKEW). NKEW editor Curtis Melvin, a Ph.D. student in economics at George Mason University, released an incredibly detailed map back in 2009, documenting railroad systems, compounds? complete with water slides?belonging to that country's elite, breweries, ostrich farms, and gulags.

"Satellite imagery is one of the few ways for foreigners to comprehend North Korea?s economic and security infrastructure, because information is so restricted," SAIS research associate Jenny Town notes in an email to Yahoo!. "Through satellite imagery we can see changes not only in the North?s missile and nuclear sites, but also markets and roads and other infrastructure which help us better understand how the North is developing. It is a good thing that Google Maps has become interested in North Korea, and we hope they will continue to refine their information."

Intense satellite scrutiny
For its part, 38 North has been closely monitoring satellite imagery to track the development of long-range missiles at North Korea's Sohae Satellite Launching Station and a possible upcoming nuclear test at Punggye-ri Nuclear Test Facility.

Analysis of new satellite imagery from January 23, 2013 and previous images dating back a month reveal that the site appears to be at a continued state of readiness that would allow the North to move forward with a test in a few weeks or less once the leadership in Pyongyang gives the order. Snowfall and subsequent clearing operations as well as tracks in the snow reveal ongoing activity at buildings and on roadways near the possible test tunnel. A photo from January 4 identifies a group of personnel, possibly troops or security guards, in formation in the yard of the administrative area near the test tunnel entrance, perhaps to greet visiting officials or for some other more routine purpose. (Jan. 25, 38 North)

The scrutiny's especially intense these days, after the United Nations's threat of sanctions if North Korea follows through with its test. A war of words has been launched, with a China editorial warning of reduced aid, South Korea's support of the resolution, and North Korea's fury directed at its southern neighbor, warning of "merciless retaliatory blows."

Yet in the meantime, leader Kim Jong Un reportedly plans to open North Korea to foreign investment, similar to Vietnam's economic development, to turn around the impoverished nation. He has already invited German economists and lawyers to plot that direction. With all this, map-watching North Korea may become a whole new online sport.

Green Blog: Market for Bear Bile Threatens Asian Population

Bears await food on a farm in Fujian Province in China that is run by the pharmaceuticals maker Guizhentang. The company legally makes tonics from bear bile.European Pressphoto Agency Bears await food on a farm in Fujian Province in China that is run by the pharmaceuticals maker Guizhentang. The company legally makes tonics from bear bile.

The six bears that arrived this month at Animals Asia, an animal rescue center in China, had the grisly symptoms of inhumane ?bile milking.? Greenish bile dripped from open fistulas used to drain gall bladders; teeth were broken and rotted from gnawing on the bars of tiny cages.

Four of the bears have since had surgery to remove gall bladders damaged by years of unhygenic procedures to extract their bile, which is coveted for its purported medicinal properties. One bear?s swollen gall bladder was the size of a watermelon.

The latest batch of bears was rescued from an illegal farm by the Sichuan Forestry Department and joins 145 other bears at the center, near Chengdu in southwestern China.
Over all, 285 bears have been rescued since the center opened in 2000

With luck, the six bears will recover at the sanctuary. But thousands on farms, both legal and illegal, continue to suffer in wretched conditions, and countless others living in the wild across Asia are threatened by poaching and their illegal capture.

Bear bile contains a chemical called ursedeoxycholic acid, long used in traditional Chinese medicine to treat gallstones, liver problems and other ailments. There are an estimated 10,000 farmed bears in China, 3,000 in Vietnam, at least 1,000 in South Korea and others in Laos and Myanmar.

Tigers, rhinos and elephants are notoriously poached to satisfy high demand in Asia for their parts, which are falsely assumed to have medicinal properties. Experts warn that sun bears and Asiatic black bears, known colloquially as ?moon bears,? are on a similar route to endangerment, although their plight draws less media attention. ?No bears are extinct, but all Asian ones are threatened,? said Chris Shepherd, a conservation biologist and deputy regional director of the wildlife trade group Traffic who is based in Malaysia.

To address the threat, the demand for bear bile must be sharply reduced, Dr. Shepherd, a conservation biologist told hundreds of researchers at the International Conference on Bear Research and Management, an annual event held recently in New Delhi.

Reducing demand would require a multi-pronged effort, experts say. That would mean enforcing existing laws, arresting and prosecuting violators, promoting synthetic and herbal alternatives, and closing illegal farms.

Chinese celebrities like the actor Jackie Chan and the athlete Yao Ming have both spoken out against the bear bile industry to raise public awareness about poaching and the inhumane conditions typically found on farms. Bears often live for years in coffin-like cages in which they are unable to stand or turn around.

The bile is extracted through catheters inserted into the abdomen, with needles or by bringing the gall bladder to the skin?s surface, where it will leak bile if prodded.

Legal farming was conceived as a way of increasing the supply of bile to reduce the motivation for poaching wild bears, according to the International Union for Conservation of Nature. But there is no evidence that it has done so, it noted in a resolution passed last September, and there is concern among conservationists that it ?may be detrimental.?

The resolution also called on countries with legal bear farms to close down the illegal ones, to ensure that no wild bears are added to farms; to conduct research into bear bile substitutes (there are dozens of synthetic and herbal alternatives) and to conduct an independent peer-reviewed scientific analysis on whether farming protects wild bears.

Some groups argue that the increased supply of farmed bile has only exacerbated demand. ?Because a surplus of bear bile is being produced, bile is used in many non-medical products, like bear bile wine, shampoo, toothpaste and face masks,? Animals Asia says. Since bear farming began in China in the early 1980?s, bear bile has been aggressively promoted as a cure-all remedy for problems like hangovers, the group added.

In mainland China and Japan, domestic sales of bear bile are legal and theoretically under strict regulation as prescription products. But such sales are illegal in Cambodia, Malaysia, Myanmar, Singapore, Thailand and Vietnam, and the international trade is illegal as well.

Yet a 2011 report from Traffic indicated that bear bile products were on sale in traditional medicine outlets in 12 Asian countries and territories.

Nonprescription bear bile products like shampoo or toothpaste are illegal in China yet are readily available for purchase, conservationists say. Tourists from South Korea, a country that has decimated its own wild bear population, are major buyers in China and Vietnam even though taking bear bile products across borders is illegal under the Convention on International Trade in Endangered Species of Wild Flora and Fauna.

?Farms have drawn in bile consumers by creating a huge market ? farmed bile is cheap,? said David Garshelis, a research scientist at the Minnesota Department of Natural Resources who is co-chairman of the I.U.C.N.?s bear specialist group.

In Vietnam, a milliliter of bile might sell for $3 to $6; about 100 milliliters can be extracted from a bear each day, according to Annemarie Weegenaar, bear and director of the veterinarian team at Animals Asia?s Vietnam center.

In four years, the I.U.C.N. is to issue a report on whether bear farms threaten wild populations. Meanwhile, demand appears to be spreading further afield in Asia and is now growing in Indonesia, largely as a result of demand from the Chinese and Korean communities there, said Gabriella Fredriksson, a conservation biologist based in Sumatra. A low-level poacher can sell a gall bladder from a bear caught in a simple snare and then killed for about $10.

So far the biggest threat to bears in Indonesia is loss of habitat from forest fires and the conversion of land to palm oil plantations. But in the last few years, poaching has increased, said Dr. Fredriksson, who has been there 15 years.

She cautioned that bears in Indonesia could also become highly threatened. ?Fifty years ago, bears were doing well in Cambodia and Laos,? she said. ?Now there?s hardly any left.?

Hydrogen sulfide: The next anti-aging agent?

Jan. 29, 2013 ? Hydrogen sulfide* (H2S) may play a wide-ranging role in staving off aging, according to a paper published online ahead of print in the journal Molecular and Cellular Biology. In this review article, a team from China explores the compound's plethora of potential anti-aging pathways.

"H2S has been gaining increasing attention as an important endogenous signaling molecule because of its significant effects on the cardiovascular and nervous systems," the team writes. The evidence is mounting, they note, that hydrogen sulfide slows aging by inhibiting free-radical reactions, by activating SIRT1, an enzyme believed to be a regulator of lifespan, and probably through its interactions with a gene, klotho, which appears to have its own market basket of anti-aging activity.

Hydrogen sulfide is produced within the human body, and has a variety of important physiological effects. For example, it relaxes the vascular endothelium and smooth muscle cells, which is important to maintaining clean arteries as one ages, says first author Zhi-Sheng Jiang, of the University of South China, Hunan. It functions as an antioxidant. And it inhibits expression of pro-inflammatory factors, all of which "imply an important role in aging and age-associated diseases," according to the paper. For example, mice lacking CSE, the gene for an enzyme involved in producing H2S, manifest extensive, premature arteriosclerosis, an inevitable consequence of aging, says Jiang.

The gene, klotho, which appears to be upregulated by hydrogen sulfide, is thought to extend lifespan via a number of different pathways, some of which promote production of endogenous antioxidants, according to the report. Produced in the kidneys, it has direct angiotensin-converting enzyme (ACE) inhibiting activity; that is, it's an ACE inhibitor, just like certain drugs that mitigate high blood pressure. Not surprisingly, plasma H2S declines with age, and is lower in spontaneously hypertensive rats than in those with normal blood pressure. More generally, a lack of H2S is implicated in cardiovascular disease.

A decline in H2S is also thought to undermine neurological health. Endogenous H2S has been found wanting in an animal model of Parkinson's disease, and is found to be depressed in the brains of patients with Alzheimer's disease. There are even suggestions, mostly in animal models, but also in human studies, that H2S may be protective against cancer, according to the report.

"Data available so far strongly suggest that H2S may become the next potent agent for preventing and ameliorating the symptoms of aging and age-associated diseases," concludes Jiang. In the future, he says, people may take H2S via food, or as an anti-aging supplement.

* Hydrogen sulfide (British English: hydrogen sulphide) is the chemical compound with the formula H2S. It is a colorless, very poisonous, flammable gas that gives off the odor of rotten eggs.

Tremors, gases will be best proof of N. Korea nuke test

SEOUL, South Korea (AP) ? With North Korea appearing set to detonate an atomic device, the U.N. agency that detected two previous tests says it is prepared to confirm an explosion when it takes place. But experts say it might be difficult to establish whether the blast is nuclear in nature.

The best indication of a test will be seismic tremors and gases released into the air, phenomena that the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty identified from previous testing.

The Vienna-based organization's most potent detection tools are more than 150 seismic stations across the globe. Although very small in yield, North Korea's first test in 2006 was picked up by the CTBTO, as was a second test in 2009.

Last week, North Korea warned that it plans a third nuclear test to protest toughened international sanctions meant to punish it for firing a long-range rocket in December. The world sees the launch as a ballistic missile test banned by the U.N., while Pyongyang says it launched a satellite into orbit as part of a peaceful space development program.

The U.S., South Korea and their allies have pressed the North to scrap its nuclear test plans, saying it will only worsen the country's decades-old international isolation.

The threats have placed scientists and experts in South Korea on high alert as any test is likely to aggravate tensions on the Korean Peninsula.

South Korea's Defense Ministry said Tuesday it believes North Korea has nearly completed its nuclear test preparations, confirming satellite analysis last week by the U.S.-Korea Institute, a research group at the Johns Hopkins School of Advanced International Studies.

U.S. Secretary of State Hillary Rodham Clinton expressed concerns Tuesday about the series of actions the North Korean regime led by new leader Kim Jong Un has taken.

"Let me express my regret, because I think with a new young leader we all expected something different. We expected him to focus on improving the lives of the North Korean people, not just the elite, but everyone to have more education, more openness, more opportunity," she said in a town hall-style meeting in Washington. "And instead, he has engaged in very provocative rhetoric and behavior.

Its satellite images of the Punggye-ri site ? where the previous two tests were conducted ? show that the North Koreans may have been sealing a tunnel into a mountain where a nuclear device would be detonated.

In the event of such an underground nuclear test, both the CTBTO facilities and earthquake monitoring stations in South Korea can detect seismic tremors.

But although this is a strong indication of a test, it is not an absolute confirmation.

An earthquake expert at the state-run Korea Meteorological Administration said his office aims to find out the magnitude of the tremor, the time it started and the exact location on the map within 10 minutes of the explosion. He spoke on condition of anonymity because he wasn't authorized to speak to the media.

Experts also note that artificial earthquakes, such as those created by nuclear explosions, rarely trigger the same wave patterns as natural quakes.

North Korea could still try to deceive and give the impression that it exploded a nuclear device by simply exploding sophisticated conventional weapons that would trigger the same seismic waves produced by a nuclear test, said Chi Heoncheol, an earthquake specialist at the government-funded Korea Institute of Geoscience and Mineral Resources.

By raising tensions this way, North Korea may hope to wrest concessions or aid in return for promises to scale back its unproven nuclear capability.

"Even if they bring truckloads of high-powered conventional explosives, put them (into an underground tunnel) and explode them, they will generate the same seismic wave and sound wave," Chi said. The only difference is no radioactivity would be detected from the explosion of conventional weapons, he said.

The best course for scientists would be to collect air samples to look for increased radiation but the process could take days. Even if the wind is favorable ? and assuming North Korea conducts the test at Punggye-ri in the country's northeastern corner ? it will take more than one day for airborne radioactive isotopes like xenon to reach South Korea, according to an official at the government-run Nuclear Safety and Security Commission.

The official, who requested anonymity citing the sensitive nature of the subject, acknowledged it may be impossible for South Korea to confirm a test if the wind doesn't blow southward or if North Korea plugs the underground tunnel so tightly that no radioactive gas escapes.

Both South Korea and the Vienna-based CTBTO confirmed increased radiation levels following the North's 2006 nuclear test but didn't find anything in 2009.

CTBTO spokeswoman Annika Thunborg says that generally speaking it is hard for those conducting nuclear tests to control the escape of noble gases, which is a clear indication of a nuclear test. With her organization's extensive air sampling network, it is less dependent on wind direction than the South Koreans in identifying such traces.

If North Korea decides to conduct a so-called subcritical test, there would be no release of radioactivity at all ? but that may be beyond the North's expertise.

A sub-critical test only works on the properties of plutonium but stop short of creating a critical mass, the point at which a self-sustaining nuclear reaction occurs. Such an experiment requires a "very difficult technology" that only a few countries like the U.S., Russia and England have acquired, said nuclear expert Whang Joo-ho of Kyung Hee University.

"I believe North Korea's technology has not reached that level," Whang said.

North Korea said its upcoming atomic explosion will be a "high-level" test and many analysts said that refers to a device made from highly enriched uranium, which gives the country a second source for manufacturing bombs in addition to plutonium.

Whether North Korea detonates a uranium- or plutonium-based device, there won't be much difference in how easily scientists can detect the tests. The only difference is that they produce different radioactive gases, Whang said.

He also said a uranium-based test explosion would mean that North Korea's nuclear stockpile can continue to be enlarged at a time when there is no evidence of continued production of plutonium at its main Yongbyon nuclear complex.

North Korea watchers in South Korea are speculating various dates for a possible nuclear test, with some predicting it could happen as early as this week and others choosing days just before the Feb. 16 birthday of late North Korean leader Kim Jong Il.

There is no way to determine when North Korea will conduct a nuclear test, said analyst Shim BeomChul at the state-run Korea Institute for Defense Analyses in Seoul. U.S. spy satellites "can detect objects 15 centimeters (5.9 inches) in size on the ground but they cannot detect what's happening underground," he said.

Science & the Public: U.S. team breaks through subglacial lake

U.S. team breaks through subglacial lake

Testing should continue for a day or more, probing for life in the Antarctic depths

Testing should continue for a day or more, probing for life in the Antarctic depths

By Janet Raloff

Web edition: January 28, 2013

Research teams from Russia, the United Kingdom and United States have each spearheaded drilling efforts over the past few years to pierce and sample separate subglacial Antarctic lakes. Russian scientists reported last year piercing into Lake Vostok but has so far turned up no identifiable life. Those researchers are now working to analyze a new sample of ice recently retrieved from that drill project. Last month, the British team suspended its efforts for this summer season (which ends next month) to reach Lake Ellsworth.

The just-completed borehole into Lake Whillans ?marks the first successful retrieval of clean whole samples from an Antarctic subglacial lake,? the U.S. team reported today. ?Water and sediment samples returned to the surface are now being processed to answer seminal questions related to the structure and function of subglacial microbial life, climate history, and contemporary ice sheet dynamics.?

A research team led by Frank Rack, of the University of Nebraska, Lincoln, recently developed and field-tested the novel hot-water drill used to cut through the roughly half-mile-deep sheet of ice to reach Lake Whillans. ?Over the whole Antarctic continent, there are more than 340 [subglacial] lakes,? he notes. ?We selected this one because we know that it goes up and down, which means that the water underneath the ice sheet is periodically filling up the lake, then draining out again.?

Researchers have monitored this cycle through a rise and fall of the surface of that portion of the ice sheet covering the lake. Each cycle can last up to a decade, Rack says.

A video camera and series of sampling instruments will be periodically lowered down the borehole in the day or two available before this portal begins freezing shut again. ?Lake Whillans has already presented surprises,? according to Doug Fox, a reporter embedded with the drill research team, which is camped out less than 400 miles from the South Pole. ?For one, the lake has turned out to be only five or six feet deep ? shallower than the 20 to 30 feet that people expected based on seismic measurements,? Fox reported in a blog on the Discover website.

When I met with the Lake Whillans research team, last month, they planned to begin analyses of retrieved water and sediment within minutes of it reaching the surface. A series of mobile research labs were recently hauled to the Lake Whillans drill site. At least one lab will be used to study the chemistry of the water.

Florida man accused of fraud after name change in 'act of love'

MIAMI (Reuters) - A newly married South Florida man who opted to take his wife's last name is fighting the state's Department of Motor Vehicles after it suspended his driving license on grounds of fraud.

Real estate investor Lazaro Sopena offered to change his name following his 2011 marriage to Hanh Dinh in order to help his wife's Vietnamese family perpetuate their family surname.

Shortly after their marriage, Lazaro Dinh obtained a new passport and Social Security card and changed his bank account and credit cards before applying to update his drivers license.

"It was an act of love. I have no particular emotional ties to my last name," said Dinh, 40, who was born in Cuba and came to the United States at the age of 11 in 1984.

His wife, Hanh Dinh, 32, has four sisters and came to the U.S. in 1990, after a family odyssey involving living in refugee camps and being separated from her father for 7 years.

Lazaro Dinh was initially issued a new license after presenting his marriage certificate at his local DMV office and paying a $20 fee, just as newly married women are required to do when they adopt their husband's name.

"It was easy. When the government issues you a new passport you figure you're fine," he said.

More than a year later Dinh received a letter from Florida's DMV last December accusing him of "obtaining a driving license by fraud," and advising him that his license would be suspended at the end of the month. Ironically, it was addressed to Lazaro Dinh.

"I thought it was a mistake," he said.

But when he called the state DMV office in Tallahassee he said he was told he had to go to court first in order to change his name legally, a process that takes several months and has a $400 filing fee.

When he explained he was changing his name due to marriage, he was told 'that only works for women,'" he said.

"Apparently the state of Florida clings to the out-dated notion that treats women as an extension of a man," said Lazaro's lawyer, Spencer Kuvin, with Cohen & Kuvin in West Palm Beach. While it was unusual for a man to seek to be considered an extension on his wife, Dinh's case raised important issues for gay marriage, he noted.

"If Lazaro isn't allowed to change his name, what is going to happen when a gay couple seeks a name change?"

Only a few states have made their marriage name change policy gender neutral, Kuvin said. In Florida's case it has no law, although the DMV's website does not specify gender.

According to Kuvin, 9 states enable a man to change his name upon marriage: California, New York, Hawaii, Louisiana, Massachusetts, Oregon, Iowa, Georgia and North Dakota.

The Florida DMV did not respond to a request for comment.

Following a DMV hearing, Dinh was issued a Final Order on January 14 confirming that his license had been properly suspended for fraud.

He is now appealing that order but has not dared get behind the wheel.

"I don't understand. I'm being treated like a highway criminal," said Dinh, who said he has a perfect driving record and now is struggling to carry out his job, begging his wife and friends for rides.

Military suicides show signs of spreading in families

Erin Trieb for NBC News

Monica Velez, pictured in Austin, Texas, had two brothers, Jose "Freddy" Velez and Andrew Velez, both of whom served the U.S. military and both are now dead -- Freddy was killed in action in Iraq, and Andrew took his own life.

By Bill Briggs, NBC News contributor

Before Army Spc. Andrew Velez left Texas for the final time, he asked his fragile sister to write him a promise ? a vow he could carry with him to Afghanistan.

Monica Velez knew she owed him that much. In the horrid weeks after each had lost their beloved brother, Freddy Velez, to enemy fire in Iraq, Monica tried to end her life with pills and alcohol. Now, she put pen to paper: ?I will not hurt myself. I will not do anything crazy. I know that Andrew loves me. I know that Freddy loved me.? Andrew folded her note and slipped it into his pocket.

?Don?t break your word to me,? he told her before heading back to war.

Seven months later, Andrew, 22, sat alone in an Army office at a base in Afghanistan. He put a gun to his head and committed suicide. Back in Texas, word reached Monica Velez who, once again, found herself in a dangerous place. Only now, she was alone. Days of alcohol and anti-depressants. Nights of dark thoughts: ?It would just be better if I was gone.?


'The storm' is coming
As the U.S. military suicide rate soared to record heights?during 2012, the families of service members say they, too, are witnessing a silent wave of self-harm occurring within their civilian ranks: spouses, children, parents and siblings.?

Some suicides and suicide attempts ? like those that ravaged the Velez family???are spurred by combat losses.

Others?may be?triggered by exhaustion and despair: As some veterans return debilitated by anxiety, many spouses realize it's now up to them???and will be for decades???to hold the family together.

Specific figures are lacking as no agency tracks civilian suicides within military families.

However, Kristina Kaufmann, a long-time Army wife, knows of three other Army wives, all friends, who took their lives in recent years.

"When you know that you are the anchor ? and if you go down, the family's going down ? the problem is that you can only do that for so long," said Kristina Kaufmann.

One was Faye Vick, described by Kaufmann as ?the perfect picture of an Army wife???pretty, nice, always with a smile.? Vick and her family lived around the corner from Kaufmann and near Fort Bragg, N.C. In 2006, when Kaufmann?s husband was in Afghanistan and Vick?s husband was deployed overseas, the 39-year-old mother placed herself, her infant and her 2-year-old son in a car inside a closed garage and started the engine, asphyxiating all three with carbon monoxide, according to Kaufmann and to local news reports at the time.

?And I know of too many others through the grapevine,? said Kaufmann, executive director of Code of Support, an Alexandria, Va.-based nonprofit that seeks to bridge the gap between civilians and military America.

?When you know that you are the anchor???and if you go down, the family?s going down???the problem is that you can only do that for so long,? said Kaufmann. ?That population (of spouses) is at the most risk. Because the storm is going to happen when everybody comes home. That?s where we are, unfortunately, going to see an uptick in lots of negative outcomes, including suicide, including suicide among the spouses.?

On Jan. 14, Department of Defense officials acknowledged that during 2012, service members committed suicide at a record pace as more than 349 people took their own lives across the four branches.?The military suicide rate is slightly lower than that of the general public. However, one active-duty member died by suicide every 25 hours last year.?

The Army sustained the heaviest branch toll at 182 suicides, which ??as NBC News reported Jan. 3?? meant that soldier suicides outpaced combat deaths for the first time, according to Pentagon officials.

Defense Secretary Leon Panetta informed Congress last July that American armed forces are in the grip of a suicide "epidemic."?

One of the darkest undercurrents of the glaring statistics is that one suicide in a family boosts future suicide risks for everyone else inside the home.?They can be contagious, say experts like Dr. Barbara Van Dahlen, a psychologist in the Washington, D.C., area and the founder of Give an Hour, which develops networks of mental-health volunteers who respond to both acute and chronic situations.

Numerous researchers have explored the so-called contagion effect of suicides within families and ?there?s no question the data supports there?s at least a doubling of risk,? among surviving family members, said Dr. Alan L. Berman, Ph.D., executive director of the American Association of Suicidology. The organization strives to better understand and prevent suicide.

?It?s understood that risk, in part, is biological,"?Berman said, given that disorders like depression have a genetic component.?

?But it?s also based on social modeling behavior: The suicide of a parent presents a model (for children in that family) of how to deal with problems, and that?s no less true for a spouse.?

Added Van Dahlen: "The closer that family member is to you, the greater risk you?re at. We believe, psychologically, it opens the possibility and ends a taboo."

?The thousands of service members who have killed themselves,? she added, ?they leave in their wake thousands of family members who are now at risk for that same kind of decision."

'I completely lost myself'
The cascade of Velez family tragedies began with pure valor.

On Nov. 13, 2004, Army Cpl. Jose ?Freddy? Velez, 23, sprayed bullets at insurgent forces???covering fire to allow other U.S. soldiers time to retreat from an enemy strong point in Fallujah, Iraq. After his ammo ran dry, Freddy Velez was shot and killed. The Army awarded him the Bronze Star and Silver Star.

"There are days I'm still overwhelmed. And if I sit and think about it, I feel like I wouldn't have to live through all this pain if I just let myself go," said Monica Velez, who shared family photos of brothers Freddy and Andrew.

Andrew, then serving with another unit in Iraq, told Monica of escorting his brother?s body home to Lubbock, Texas ? a job, he said, that required unzipping his brother?s body bag at every stop to re-verify Freddy?s identity.

During the trip, Andrew called his sister repeatedly while en route home and screamed into the phone for nearly two consecutive hours, ?like somebody was killing him,? she said.

?There was nothing I could do,? Monica Velez recalled. ?The operator kept cutting in (to request additional payment for the call) and I just said, ?Add it to my credit card.? He just wailed. That travel home, I think is what eventually broke him.?

Weeks later, Monica broke.

She doesn?t know how close she came to death the first time she tried to end her life. She never was told how slow her pulse became that night. She just remembers regaining consciousness at a hospital in Killeen, Texas???home to Fort Hood, where Freddy was based. She awoke with an IV plugged into her arm. A doctor handed her a list of local psychiatrists then discharged her.

Velez tried, she said, to seek help for her deepening depression but was told that her health insurance would not cover counseling.

Her grief was rooted in a difficult childhood, she said, that forged "tighter than tight" emotional bonds between Velez and her two brothers, turning the siblings into a mutual support group.

?When Freddy passed away, I went through a really hard depression,? she said. ?I went to the emergency room for anxiety attacks. I couldn?t breathe. But nobody knew how to deal with me so they just gave me Ativan (an anti-anxiety drug) and Hydrocodone (a pain killer).

?I started drinking heavily and taking the prescriptions. And one day, I just felt it would be better off if I wasn?t around and decided to take all of the pills. Grief can bring you to that breaking moment.?

Soon after, in February 2005, Andrew sent his older sister (then 25) an email: ?We need to be stronger. We need to protect each other.?

Though he was the youngest of the siblings, Andrew always was ?the strong one,? his sister said. ?But he and Freddy were inseparable.? Near the end of 2005, Andrew told his sister he was redeploying to Afghanistan because, she said, ?I think he felt closer to Freddy there.?

From March through July of 2006, the two swapped calls and emails. In Afghanistan, Andrew grew increasingly despondent, she said, over the unraveling of his marriage and family in Lubbock. He had three children. But he worried, too, about his sister?s state of mind.

?We could both hear it in each other?s voices. He was scared I was going to do something. I was scared he was going to do something.?

He did. Andrew?s suicide on July 25, 2006, drove Monica, at first, into 20-hour workdays at a domestic violence shelter. She wasn?t sleeping or eating. Eventually, she was drinking again, ?from the morning until I passed out,? she said. ?Then, doing it again the next day.

?I completely lost myself. I resigned my job. I stopped paying my bills. I got evicted. I was prescribed anti-depressants. I noticed taking the pills and drinking got me out of the emotions. So I found myself in a dangerous place very quickly.

?Again???several trips to the ER (for overdoses). I?m not sure why I wasn?t ever held there. In my down periods, I would tell myself it would just be better off if I was gone.?

In 2008, a friend at Fort Hood, Texas, connected Velez with the Tragedy Assistance Program For Survivors (TAPS), a resource for anyone who suffers the loss of a military loved one.

?That was the first time anybody had offered to help me with the depression and the grief.? she said.

'Family units breaking down'
Kaufmann, who lost three Army-spouse friends to suicide, argues that military-family suicides should be tracked and researched by the Department of Defense to help mental-health experts begin to slow or stop the problem. She knows, however, such an accounting is not likely.?

?I get the sense that people in the military think that by including families into this kind of discussion ? particularly when you?re talking about the (broader) mental-health impacts on family members ? they look at that as something that will only add to the problem. Whereas, we believe that it would prove to be a solution,? Kauffman said.

?We?ve approached this very myopically. More than half of soldiers are married. Soldiers come with families. And the military has a maddening way of both dismissing families and holding them accountable at the same time. It?s frustrating for us, not only when we?re trying to get our husbands help, but also when you have the family units breaking down,? she added.?

NBC News requested to speak with officials at the newly formed Department of Defense suicide-prevention office about the issue of suicides within military families and whether tracking is needed. A DOD spokeswoman said, however, that the office is only working to address active-duty suicides. The interview request was not granted.

Van Dahlen, meanwhile, believes that asking DOD to track military families is an unreasonable expectation to place on the agency when it already is facing budget cuts.

Even if the DOD wants to ? and many of my colleagues there desperately would want to devote resources to this???those resources are not going to be there,? she said. Rather than putting "the screws to DOD" and doing "even more with even less," Van Dahlen believes public-private partnerships should be encouraged "to figure out how we can (address) this together."

'Like an airborne disease'
More than eight years after Freddy?s combat death, and more than six years removed from Andrew?s suicide, Monica Velez annually runs the Marine Corps Marathon in Washington, D.C., in honor of her fallen brothers.

Matt Slocum / AP file

Monica Velez cleans her brother's name, engraved in a memorial at Fort Hood, Texas.

But, now living in Austin, she acknowledges she still struggles with what she calls, ?those thoughts.?

?There are days I?m still overwhelmed. And if I sit and think about it, I feel like I wouldn?t have to live through all this pain if I just let myself go. It doesn?t just go away. But you learn how to cope. You learn better coping skills,? she said, adding she gained those tools from TAPS.

Army officers at Fort Hood have occasionally asked her, she said, for ideas to help them prevent the rising military suicide rate. She watches that tally, too.

?The numbers take my breath away. I know it can be overwhelming for the Army generals on the other end of the table trying to figure this problem out. Because it?s like an airborne disease going through the building and you?re trying to figure out how to stop it before it gets to you," she said.?

?But it?s coming at a really fast rate, and it?s inevitable.?

Quantum theory of smell causes a new stink

Jacob Aron, reporter

The first evidence from tests on people that our ability to distinguish between different scents involves quantum mechanics has reopened a long-standing debate.

Most researchers think a molecule's odour is determined by its shape, with smells triggered when the molecule enters a suitably shaped receptor in the nose, like a key entering a lock. Luca Turin of the Fleming Biomedical Research Sciences Centre in Vari, Greece disagrees, because some molecules with different shapes have similar smells.

In 1996 he proposed that a smell receptor would only fire when a molecule vibrated at the right frequency. These vibrations provide enough energy to trigger a quantum tunnelling effect, causing an electron to pass across the receptor and trigger a smell.

One way to test the theory is replacing the hydrogen atoms in a molecule with deuterium, a hydrogen isotope with a nucleus of a neutron and a proton, rather than just a proton. The shape of the molecule barely changes, but the added neutrons alter the frequency of its vibrations. Turin's previous experiments have shown fruit flies can distinguish between the original and altered versions of acetophenone, a common perfume ingredient, but similar tests on humans had failed.

Now Turin and colleagues have attempted the same experiment with larger molecules and discovered that?humans can detect a significant difference in odour. They put this down to an increased number of carbon-hydrogen bonds in the larger molecules, as these bonds maybe responsible for the vibrational effect.?

Researchers supporting the shape model of smell remain unconvinced though, with?Tim Jacob?of Cardiff University, UK telling the?BBC?that the new results were "supportive but not conclusive".

Meanwhile,?Ilia Solov'yov?of the University of Illinois at Urbana-Champaign,?told Chemistry World?he was "not convinced" the results prove humans could smell the difference between the two types of molecules.

More broadly, there is increased interest in the?quantum biology, including recent evidence that?birds may use quantum mechanics to navigate.

Gauge of business spending plans edges higher

WASHINGTON (Reuters) - A gauge of business confidence improved in December, a sign that business worries over tighter fiscal policy may not have held back investment plans as much as feared at the end of 2012.

The Commerce Department said on Monday that non-defense capital goods orders excluding aircraft, a closely watched proxy for investment plans, edged 0.2 percent higher.

Many economists believe businesses held back on capital spending late last year because of uncertainty over government spending cuts and tax increases that had been scheduled to kick in this month. Congress ultimately struck a last-minute deal in early January to avoid or postpone most of the austerity measures.

Monday's data showed companies appeared to still be planning to expand their businesses.

"There's a lot more confidence," said Wayne Kaufman, an analyst at John Thomas Financial in New York.

In a further sign that firms are betting their business will grow, the investment plans proxy for November was revised higher to show a 3 percent gain.

Overall durable goods orders jumped 4.6 percent in December, beating economists expectations of a 1.8 percent gain.

Scientists at Arizona State University are celebrating their recent success on the path to understanding what makes the fiber that spiders spin weight for weight - at least five times as strong as piano wire. They have found a way to obtain a wide variety of elastic properties of the silk of several intact spiders' webs using a sophisticated but noninvasive laser light scattering technique.

"Spider silk has a unique combination of mechanical strength and elasticity that make it one of the toughest materials we know," said Professor Jeffery Yarger of ASU's Department of Chemistry and Biochemistry, and lead researcher of the study. "This work represents the most complete understanding we have of the underlying mechanical properties of spider silks."

Spider silk is an exceptional biological polymer, related to collagen (the stuff of skin and bones) but much more complex in its structure. The ASU team of chemists is studying its molecular structure in an effort to produce materials ranging from bulletproof vests to artificial tendons.

The extensive array of elastic and mechanical properties of spider silks in situ, obtained by the ASU team, is the first of its kind and will greatly facilitate future modeling efforts aimed at understanding the interplay of the mechanical properties and the molecular structure of silk used to produce spider webs.

The team published their results in today's advanced online issue of Nature materials and their paper is titled "Non-invasive determination of the complete elastic moduli of spider silks."

"This information should help provide a blueprint for structural engineering of an abundant array of bio-inspired materials, such as precise materials engineering of synthetic fibers to create stronger, stretchier, and more elastic materials," explained Yarger.

Other members of Yarger's team, in ASU's College of Liberal Arts and Sciences, included Kristie Koski, at the time a postdoctoral researcher and currently a postdoctoral fellow at Stanford University, and ASU undergraduate students Paul Akhenblit and Keri McKiernan.

The Brillouin light scattering technique used an extremely low power laser, less than 3.5 milliwatts, which is significantly less than the average laser pointer. Recording what happened to this laser beam as it passed through the intact spider webs enabled the researchers to spatially map the elastic stiffnesses of each web without deforming or disrupting it. This non-invasive, non-contact measurement produced findings showing variations among discrete fibers, junctions and glue spots.

Four different types of spider's webs were studied. They included Nephila clavipes (pictured), A. aurantia ("gilded silver face"-common to the contiguous United States), L. Hesperus the western black widow and P. viridans the green lynx spider, the only spider included that does not build a web for catching prey but has major silk elastic properties similar to those of the other species studied.

The group also investigated one of the most studied aspects of orb-weaving dragline spider silk, namely supercontraction, a property unique to silk. Spider silk takes up water when exposed to high humidity. Absorbed water leads to shrinkage in an unrestrained fiber up to 50 percent shrinkage with 100 percent humidity in N. clavipes silk.

Their results are consistent with the hypothesis that supercontraction helps the spider tailor the properties of the silk during spinning. This type of behavior, specifically adjusting mechanical properties by simply adjusting water content, is inspirational from a bio-inspired mechanical structure perspective.

"This study is unique in that we can extract all the elastic properties of spider silk that cannot and have not been measured with conventional testing," concluded Yarger.

Internet Marketing: What Does it Really Mean? | Business Tips ...

Jan 27, 2013 by Victorino Abrugar at Online Marketing

Doing Internet marketingWhat is Internet marketing or online marketing? When we hear the word ?Internet?, the usual words that suddenly pop up in our mind are email, website, Google, Facebook, Twitter, and YouTube. And when we are asked about marketing, we begin thinking about business, brand, product, advertising, and customers.

So if we are to be asked what Internet marketing is, our basic answer could be the process of using the Internet which is composed of websites, search engines, and social media to promote a business, brand or product in order to attract more customers and increase revenue. And if you want to make its definition even shorter, Internet marketing could be the process of marketing a product or service over the Internet.

However, the Internet is not just all about emails and websites or about search engines and social media. The Internet is a huge online world that every business owner, entrepreneur or marketer should explore further in a consistent manner. Moreover, marketing is not all about advertising your products to attract more customers and increase your revenue. Marketing also includes ensuring your product, price, distribution, processes, and extra services to be satisfying and useful to customers.

The people on the Internet

The Internet cannot exist without people. The online world cannot exist without the people who are using it or even living on it. For example, search engines like Google are useless without the people who are using them to search information. Moreover, social media like Facebook and Twitter are dead without the people who are using them and interacting with each other every day.

Thus, when you are marketing your product or service on the Internet, you are not actually promoting it to the search engines or the social networking sites, but you are promoting it to the people who are the primary users of search engines and social media. Hence, if a person is destroying the usefulness of emails, search engines, and social media by spamming and annoying people? can we say that he is doing Internet marketing? And even if a person is using the Internet the right way through legitimate online advertising schemes but not providing the quality of the product he promised? can we call him a real Internet marketer?

The real Internet marketer

Being a real Internet marketer is not only measured by his technical expertise in website development, link building, content writing, making a web page rank higher in the search engines, and getting many likes on Facebook or retweets on Twitter. A real online marketer is not also measured by the instant profit he can generate out of his online marketing efforts. But a genuine Internet marketer is someone who can make people smile and thank him for the solution he brought to them, causing this to reward him long-lasting profits.

As you will realize, Internet marketing is for the people on the Internet. Whether it is online or offline marketing, marketing should be focused on people. And when we use Internet marketing, it only means we are targeting the people who are using the Internet. If we want to use online marketing to achieve business success, we have to focus not only on how we can use the Internet to promote our business, but we also have to concentrate on how people use the Internet to satisfy their needs.

The meaning of Internet marketing

Internet marketing is the process of using the Internet (website, search engines, social media, email, blogs, etc.,) and analyzing how people use the Internet to satisfy target customers by providing them the product or solution they need.

Internet + marketing = Internet marketing

Internet is everything on the Internet, including websites, emails, search engines, social media, online processes, web applications, and the people who are using it.

Marketing is your product, price, place (distribution), promotion (advertising), process, people (marketing team) + other elements that will satisfy customers and help you achieve your marketing goals.

Therefore, whatever type of Internet marketing you are using, whether it is social media marketing, search engine optimization, email marketing or anything else, make sure to satisfy and wow your target users or customers.

Coltart on new board - The Standard

MINISTER of Education, Sport, Arts and Culture David Coltart has thrown his weight behind the new Zimbabwe National Boxing and Wrestling Control Board membership.

Report by Brian Nkiwane

Coltart said with the assistance of the Sports and Recreation Commission, they had taken time to come up with the final list of board members which they had mandated to revive boxing.

Boxing made headlines during the era of the late legend Proud ?Kilimanjaro? Chinembiri but later fizzled out.

?As the powers behind this, we are sure that we did a good job. We looked at the experience the person has in the sport. We then came up with a board composed of former boxers, promoters, a medical doctor and a media practitioner. We want people who are going to revive this sport,? Coltart said.

The new board members are set to receive letters of appointment next week.

The state of boxing in the country has been in dire straits with no substantive board for over a decade.

Last week, boxer Tinei Maridzo was quoted in the press urging the minister to appoint the board for the revival of the sport.

List of board members:
Paul Nenjarama (Chairman)
Lorraine Muringi
Frederick Farai Muchena
Edgar Peter Jack Hammond
Tsitsi Muzuva
Alexander Kwangwari
Gilbert Munetsi
Rangarirai Charles Dzimba
