How Cosmic Rays Can Image the Throat of an Active Volcano [Video]

Features | More Science

Cosmic-ray muons that pass through Mount Vesuvius could reveal the interior structure, potentially indicating when the deadly volcano will next erupt. A video from NOVA

The volcano that buried Pompeii in A.D. 79 still rumbles deep down. Last erupting in 1944, Mount Vesuvius poses an ever-present threat to the Italian populations around Naples. Whether the volcano will erupt in Pompeiian proportions again is a question that preoccupies scientists monitoring it, as they hope to predict when Vesuvius will blow and provide adequate warning time.

One way to gauge the magnitude of an impending volcanic eruption is to determine the size of its "throat"?the internal tube through which magma travels upward to the surface. The larger the tube, the bigger the eruption is likely to be.

Hiroyuki Tanaka of the University of Tokyo reasoned that the throat could be "x-rayed" with energetic muons produced in cosmic-ray showers. The number of muons passing through the volcano would depend on the density of intervening rock, so measuring the number of muons passing through various parts of the volcano could yield a crude, 3-D view of the interior.

This clip from "Deadliest Volcanoes," by PBS's NOVA, provides a look at muon imaging. The entire NOVA program explores the threats from volcanoes around the world, including the supervolcano below Yellowstone National Park and the eruption threat in the U.S. Pacific Northwest. It airs on Wednesday, January 4, at 9 P.M. on PBS.

Drew Brees Helps Saints Set NFL Record For Offensive Yards

NEW ORLEANS -- The New Orleans Saints have set an NFL record for the most yards of offense in a season.

The 2000 St. Louis Rams held the previous mark of 7,075. New Orleans eclipsed that number in the second quarter of Sunday's season finale against the Carolina Panthers on a pass from Drew Brees to Robert Meachem, reaching 7,081.

The record by the Saints comes one week after Drew Brees passed Dan Marino's 27-yard-old mark for yards passing. He entered this week's game at 5,087 yards and added 140 through a little more than a quarter against Carolina.

Brees' first TD pass also gave the Saints a franchise record for points in a season with 516, breaking the 2009 mark of 510.

Red Digital Cinema sues competitor Arri over e-mail hacking, adds new charges to the list

The behind-the-lens drama between camera makers Red Digital Cinema and Arri has taken yet another step recently, as Red filed suit December 21st against Arri alleging corporate espionage. Former Arri executive Michael Bravin has already plead guilty to criminal charges that he illegally accessed emails at his previous employer, camera distributor Band Pro Film & Digital. At the time Red founder Jim Jannard also revealed his personal account had been compromised, and now The Wrap reports the company is accusing Arri of "unfair competition based on email hacking, invasion of privacy, conversion, misappropriation of trade secrets and unlawful trade practices, among other charges". The extra charges come as a result of information it has indicating other Arri executives were aware of the hacking. Other than listening in on conversations between Red and Band Pro, Arri also stands accused of launching a false advertising campaign ahead of the launch of the Alexa, while Bravin posted with a pseudonym on RedUser.net. Hit the source link for additional details on the sordid affair, we'll find out what can be proven if / when Red gets the jury trial it's seeking.

Readers write (Jan. 2): Mitt Romney, state GOP scandal, energy dispute, nonprofit pay, bipolar disorder

MITT ROMNEY

Doesn't seem like he's just one of us

?

In an effort to present her multimillionaire husband as just a reg'lar guy and one of us middle-class strivers, Ann Romney notes that "we have had the most fun times in the world, literally, on horseback, in the mountains" (Dec. 13).

I don't even have a horse, and I'm guessing that the vast majority of Americans don't, either. So it's rather comical that, in her effort, she has exposed the elitism that many of find patronizing. It's understandable.

The Republican Party is the party of money (protect our wealth, legislate to allow its growth), but it's rather symbolic when the wife of a very wealthy presidential hopeful uses an analogy that practically none of us can relate to. Sorry, Ann.

STATE GOP SCANDAL

Koch's relationship is irrelevant. Next?

?

The level of hypocrisy (pretended sanctity) and naivety is unsurpassed regarding the "inappropriate relationship with Senate staffer" that led to the resignation of state Senate Majority Leader Amy Koch.

Both letter writers and editors are way off-base on this one. Some want Koch to resign because she lied and apparently committed adultery. By that standard, I'd guess that every member of our Legislature would have to retire from public office.

(I don't recall that Bill Clinton resigned. Oh, I forgot, his episodes only involved oral sex in that little room off the Oval Office.)

Koch is not the first and won't be the last "boss" to have an affair with a subordinate. Her private life has nothing to do with the marriage amendment. So she's hypocritical -- so what? Who isn't or hasn't been?

The Dec. 28 editorial was nonsense. Who cares why she left "leadership" or when? So what if she was or wasn't forced out? If anyone feels GOP communications director Michael Brodkorb was forced out illegally -- go to court.

God knows we've got enough lawyers to help him. Bottom line: Put this event to bed and move on. The amendment will be voted on in due course. Give it a rest until then.

ENERGY DISPUTE

North Dakota makes its allegiances clear

?

North Dakota is going to bat for the energy companies operating within its borders; it is willing to cover more than half the cost of a legal battle with Minnesota over this state's refusal to buy electricity produced by that one's "dirty" coal plants ("Utilities help N. Dakota foot bill for lawsuit," Dec. 29).

North Dakota admits the companies don't meet emissions standards but argues that standards don't matter. It cites federal rules that allow companies with dirty emissions to "swap" them with clean companies elsewhere.

This seems ironic. Earlier this year, North Dakota set aside a million dollars in tax revenue to fight any federal rules that would lead to greater scrutiny by the EPA of the state's ground water as a result of hydraulic fracturing, or "fracking," by the oil industry there.

The state's picking and choosing of federal rules makes me question its principles. It is obvious that it is for permissive rules, but against rules that call for public safety and accountability.

I would also think the state's actions would make residents wonder whose interests are being served by their representatives in Bismarck.

I'd ask why are my tax dollars being used to fight on behalf of the coal and oil industry, which profits by lower standards and less oversight, rather than to protect and serve the interests of the North Dakotans. It's not as though the oil and coal industries are down and out and can't afford their own legal representation.

NONPROFIT?PAY

Front-line workers need, deserve raises

?

As someone who has been employed as a direct-care worker in group homes for more than 15 years and as an engineer prior to that, I feel compelled to add my opinion to the recent discussion among letter writers about executive compensation at nonprofits.

It has been my experience, in both for-profit and nonprofit settings, that once people become part of management and can set their own wages, they compensate themselves well, yet have no problem justifying why they can't pay the people who do the front-line work a living salary.

During years of not receiving raises, or getting 1 percent raises, I watched my coworkers work second jobs in order to survive. Many, like me, eventually had to leave careers that they loved in order to earn living wages.

My question is: Why is it that managers and CEOs of nonprofits feel that paying competitive wages is crucial to keeping themselves employed and not the devoted workers who make a difference to people and their families?

BIPOLAR?DISORDER

It needn't be an obstacle to success

?

I am so glad that Ray Pearson received the proper diagnosis ("Teen's correct diagnosis was exception, not rule," Dec. 30). Bipolar disorder is a tough mental illness to treat, especially when a child is young. I'm happy he's taking steps to move forward.

What ticks me off are all the ignorant people (including some of his teachers) who told him that college probably wasn't an option due to his illness. Some of the world's most talented people are cited as having struggled with the disease, including:

? Adam Ant (singer)

? Sting (singer)

? Russell Brand (actor)

? Dick Cavett (interviewer)

? Rosemary Clooney (singer)

? Ray Davies (singer)

? Richard Dreyfuss (actor)

? Patty Duke (actress)

? Carrie Fisher (actress)

? Florence Nightengale (nurse)

? Jane Pauley (journalist)

? Margaret Trudeau (former wife of prime minister of Canada)

? Vincent Van Gogh (painter)

? Amy Winehouse (singer)

? Virginia Woolf (writer)

Don't let anyone tell you that you can't achieve! I earned a master of science degree and was diagnosed when I was 18. With the proper medication and therapy when necessary, you can live a perfectly normal life.

You thought 2011 was tough? (Reuters)

NEW YORK (Reuters) ? Shaky Europe. Political gridlock. Volatile markets.

Familiar themes for those who lived through 2011, and investors should be ready to revisit them next year.

With a spiraling debt crisis in Europe, political upheaval around the world, and crumbling creditworthiness in major industrial nations, 2011 was a tough year to know where to invest. 2012 is unlikely to offer much respite.

The S&P 500, a measure of the biggest U.S. companies' market value, spent much of the year getting pushed up and down, flummoxing shorts and longs - and scaring Moms and Pops away from stocks. It ended the year at 1,257.60, down a mere 0.04 of a point.

But the S&P 500's tepid performance was encouraging, compared with other world equity markets. The United States may still be seen as a safe haven, though even that looks uncertain.

For every rally built on improving economic figures this year, selloffs were never far away on worries the European debt crisis would eventually drag the continent into a recession and perhaps the United States as well. That could continue in 2012.

China and other fast-growing emerging markets can no longer be leaned on as those economies slow. In 2011's last half, the poorest-performing sectors outside of banks were most connected to global growth - materials, energy and industrial companies.

"There is a growing realization that the global economy is in jeopardy," said Bruce Bittles, chief investment strategist at Robert W. Baird & Co in Nashville. "There is uncertainty in every corner of the world."

That uncertainty fed substantial volatility in 2011. Despite the S&P's flat performance this year, there were 66 trading days when stocks moved in a 2 percent range. In 2008, when Lehman Brothers collapsed during a global financial crisis, there were more than 130 trading days when stocks swung that much. But that led to a flight from equities by retail investors.

U.S. equity funds had outflows in every month since May. More than $483 billion left U.S. mutual funds in 2011 through the year's second-to-last week, even though the U.S. market outperformed foreign stocks late in the game.

BEATING GLOBAL RIVALS

The S&P 500 ended the year off a scant 0.003 percent, the closest it has come to unchanged since 1947, according to Standard & Poor's. The Dow Jones industrial average (.DJI) finished 2011 with a 5.5 percent gain, while the Nasdaq Composite Index (.IXIC) slipped 1.8 percent.

In contrast, the MSCI world stocks index (.MIWD00000PUS) fell 9 percent, while the FTSEurofirst-300 index (.FTEU3) slid nearly 11 percent.

The darlings in the emerging markets fared the worst. China's Shanghai Composite index (.SSEC) lost 22 percent, India's BSE (.BSESN) sank 25 percent, and Brazil's Bovespa (.BVSP) dropped 18 percent.

Strategists say the U.S. stock market may benefit from reasonable economic growth and attractive market valuation. The S&P 500 is expected to rise 6 percent by the end of 2012, according to the most recent poll of Wall Street strategists.

When Wall Street gets back to work on Tuesday, it will face a holiday-shortened week and a slew of economic indicators. The most crucial numbers will come on Friday when the government will release the December non-farm payrolls report. Economists polled by Reuters expect a December gain of 150,000 jobs, compared with an increase of 120,000 jobs in November.

Volatility is likely to persist through early 2012 because of the uncertainty in Europe and rising concern about slowed earnings growth due to recent revisions.

The S&P 500's price-to-earnings ratio - what investors are willing to pay for a dollar of earnings - is under 12, below the 25-year average of 15. In weaker markets like Germany's DAX, the figure is below 9.

"We're building in a massive recession into these numbers," said Marc Pado, U.S. market strategist at Cantor Fitzgerald & Co. in San Francisco.

U.S. companies cutting earnings' outlooks recently outpaced those raising theirs by the greatest ratio in 10 years. Some sectors, such as materials, have seen a sharp drop in forecasts for the fourth quarter, Thomson Reuters data showed.

Last week, downbeat earnings from Oracle Corp (ORCL.O) shook confidence in the tech sector's health before the quarterly earnings season's start in January. Oracle joined a growing list of companies, including some of technology's biggest names, whose results and outlooks have set off alarm bells.

Next year, S&P 500 earnings are seen rising 9.9 percent, down from an estimate of 13 percent in October.

RECESSION FEARS

Many economists believe the euro zone is already in recession. They forecast that the economies of the 17-nation bloc will stagnate in 2012 after contracting in this year's fourth quarter and the first quarter of the next.

Investors are worried that Italy and Spain will have to keep refinancing borrowings at unsustainable levels early next year, which could escalate the crisis.

The correlation between the U.S. stock market and the euro skyrocketed in 2011 as investors tied bets on risky assets to the euro's moves. That trend ebbed as equities rallied near the end of the year, but it is likely to flare up again.

So far the U.S. economy has stayed on course for moderate growth. Economists expect it to expand by about 2.1 percent next year. But it is unclear how a slowdown in the rest of the world will affect the economy stateside.

The key may be China rather than Europe.

"China is the 800-pound gorilla in the room and is probably the most important country to watch in terms of their contribution to global growth," said Michael Sheldon, chief market strategist at RDM Financial in Westport, Connecticut.

Chinese business confidence is weakening. A survey showed export orders fell for the first time in nearly three years.

The drop in materials shares in 2011's second half reflects worry about declining activity overseas. The S&P Materials Index (.GSPM) lost nearly 14 percent in the last six months.

GRIDLOCK SHOCK

One of the pivotal events of 2011 was the downgrade of the United States' perfect triple-A credit rating. Standard & Poor's cited congressional bickering as the reason for the downgrade.

August's stalemate in Washington over raising the debt ceiling sparked a selloff that accelerated after the downgrade.

Investors expect the gridlock in Congress to get worse as the U.S. presidential election approaches in November. The election is likely to be close, which will not make legislative efforts to tackle high debt levels and weak demand any easier.

Rancor was in view again in December as Congress struggled to pass a two-month extension of U.S. payroll-tax cuts.

"There will be less certainty about taxation and regulation so that will inhibit business formation and business growth," said Brian Battle, a trader at Performance Trust Capital Partners in Chicago.

Goldman Sachs sees global growth highly susceptible in 2012 to even minor shocks - and those shocks may be political.

"Slowing growth (and in places outright contraction), public-sector cuts, and a renegotiation of the social compact between state and society in different parts of the world is an environment ripe for political turmoil," Goldman said in a note to clients.
