Morning-After Pill Appeal Filed By Justice Department

NEW YORK ? The Obama administration on Monday filed a last-minute appeal to delay the sale of the morning-after contraceptive pill to girls of any age without a prescription.

The legal paperwork asked the 2nd U.S. Circuit Court of Appeals in Manhattan to postpone a federal judge's ruling that eliminated age limits on the pill while the government appeals that overall decision.

U.S. District Court Judge Edward Korman has said that politics was behind efforts by Secretary of Health and Human Services Kathleen Sebelius to block the unrestricted sale of the Plan B One-Step morning-after pill and its generic competitors.

Last month, he ordered that the levonorgestrel-based emergency contraceptives be made available without prescription and without age restrictions. He then denied a request to postpone his ruling while the government appealed, but gave them until Monday to appeal again.

Government attorneys warned that "substantial market confusion" could result if Korman's ruling was enforced while appeals are pending. On Monday, lawyers argued that the district court "plainly overstepped its authority," and that they believe they will win the overall appeal.

Attorneys for the Center for Reproductive Rights have said in court papers that every day the ruling is not enforced is "life-altering" to some women. They have 10 days to respond to the most recent government filings, after which the appeals court will issue a decision.

If the government fails, it would clear the way for over-the-counter sales of the morning-after pill to younger girls. The FDA announced earlier this month that the contraception could be sold without a prescription to those 15 and older, a decision Korman said merely sugarcoated the appeal of his order lifting the age restriction.

Sales had previously been limited to those who were at least 17.

The judge said he ruled against the government "because the secretary's action was politically motivated, scientifically unjustified and contrary to agency precedent" and because there was no basis to deny the request to make the drugs widely available.

Future of house where Ohio victims held debated

(AP) ? An imposing, 10-foot privacy fence will soon guard the home of Cleveland rape and kidnapping suspect Ariel Castro, with windows and doors boarded shut to keep people out of the place that police say was once meant only to keep people in.

The run-down house has become a two-story piece of evidence in the abduction and imprisonment case of three women, but neighbors who remain shaken by the horrors alleged inside want it torn down and erased from the landscape of Seymour Avenue.

"The girls that was in that house, when they ride by there, if they ever ride by there again, they won't have to see that, to remind them or maybe scare them," said Johnny Wright, 54, who can see the back of the house from his front door. "What they went through, I don't think any human being should ever been through that."

The house and what becomes of it will be a daily talking point for the Seymour community, as city officials deal with the irony of keeping the dreaded site of the women's imprisonment safe while neighbors almost uniformly want it torn down.

The issue isn't a simple one.

First and foremost, it's evidence against Castro, who investigators say kept the women in chains in a basement before eventually allowing them to live under close control upstairs. The 6-year-old daughter of one victim, Amanda Berry, was also freed; DNA tests showed Castro was her father, a dark twist on years of captivity during which Castro is also alleged to have induced multiple miscarriages in one of the women by repeatedly punching her belly.

The nondescript white house with a red-and-white tile roof sits on a street of other boarded-up houses, victims of the foreclosure crisis which hit the city hard. The house has thousands of dollars in unpaid tax liens, which would have to be sorted out as the city attempts to control the property. County records show it was built in 1890 and updated in 1950. Forty-two years later, Castro bought it for $12,000.

Workers over the weekend began boarding up windows and doors and erecting a metal fence around the house.

The plywood and fence have a two-fold purpose, said Councilman Brian Cummins: preserving the scene as evidence and protecting it from the threats already circulating on the streets to burn it down in a stroke of vigilante justice.

It's a decision for neighbors and also for the women, said Cummins, whose ward encompasses the property and who is in close contact with police and city officials about the situation.

"The issue is how do we respect the wishes of the survivors in this case and it's too premature to know what their wishes would be," Cummins said Saturday.

There's precedent for tearing down scenes of terrible crimes.

In 2011, Cleveland tore down a house on the city's east side where 11 women were killed over several years by a serial murderer now on Ohio's death row.

But first it served as evidence against Anthony Sowell: in June 2011, jurors walked through the house wearing face masks to ward off the smell of decay as Sowell's trial got under way.

That house also had to be protected before trial from people furious at Sowell's crime.

As with the Sowell house, both prosecutors and the defense will want Castro's home still standing until the trial ends, said Michael Benza, criminal law professor at Cleveland's Case Western Reserve University.

"The prosecutors are going to want to preserve it so they can take jurors into it to view, and the defense would want it preserved so at least they could do their own investigation," Benza said.

It's unlikely the house would be needed once the trial ends; typically only evidence like weapons or fingerprints are preserved for appeals, he said.

Almost 30 years ago in Chicago, the vacant house where John Wayne Gacy killed at least 33 teenage boys and young men was demolished.

More recently, a panel in Connecticut voted Friday to tear down Sandy Hook Elementary School where 20 first-graders and six educators were gunned down in December and build a new school on the same site.

Demolition isn't always the answer. Columbine High School, site of a 1999 school shooting that killed 12 students and a teacher, replaced the library where most of the killing happened with a new library. Chardon High School in northeastern Ohio, where three teens were killed in February, repainted the cafeteria where the shooting happened and put in new tables.

Evidence is crucial in such cases and can be an issue when considering demolition.

Last year in Connecticut, parents of three girls killed in a 2011 Christmas morning fire served notice they planned to sue the city of Stamford, accusing officials of intentionally destroying evidence when they demolished the shoreline home a day after the fire.

Victims' wishes aren't always responded to when it comes to such crime scenes. Cinemark reopened a theater in Aurora, Colo., earlier this year that was the site of 12 people killed in a July shooting.

Relatives of several of the victims rejected an invitation to attend its planned reopening, calling it a "disgusting offer" that came at a terrible time ? right after the first Christmas without their loved ones.

Betsy Medina, a nurse's aide who lives behind Castro's house with her three children and her fiance, says tearing it down would spare the three women having to see it again.

Elsie Cintron, who lives three houses down from the house, rejected any idea of keeping it up.

"It'd be a horrifying thing for anybody to go through there thinking something else might happen with the house still standing," she said. "It could be boarded up, locked up ? don't mean somebody can't get in from the back and do something else."

Pastor Horst Hoyer, who leads the nearby Immanuel Lutheran Church, said he took comfort in knowing the women would have heard the bells of his nearby church during their captivity. He agrees with neighbors, calling it "a house of shame."

He said the bells of his church, which once rang to call parishioners to worship, are the only good memory he can have of what happened just down the street.

"They served a real purpose," he said Saturday. "I'm sure they must have given those good ladies hope and what day of week it is and what holiday it is, and were the one thing Mr. Castro couldn't stop going into that house ? those sounds."

HP LaserJet Enterprise 700 Printer M712dn


Relatively few business printers can print at up to tabloid size (11-by-17), and the HP LaserJet Enterprise 700 Printer M712dn is a welcome addition to that club, bringing very good paper handling, low running costs, and good speed. Although its output quality could be better, the M712dn is a good choice for high-volume black-and-white printing, including at tabloid size.

Unlike most of the tabloid printers we've tested in the past few years, the M712dn is a monochrome printer. It measures 15.4 by 22.4 by 23.4 inches (HWD) and weighs 85 pounds, too big to share a desk with, and you'll want at least two people to help move it into place. The M712dn has a 600-sheet standard paper capacity, between two 250-sheet input trays and 100-sheet multipurpose feeder. (One of the two 250-sheet trays, plus the feeder, can handle tabloid-sized paper.) An abundance of feeders, extra trays, and floor-standing cabinets are available as accessories. This printer has an automatic duplexer for printing on both sides of a sheet of paper. It has a maximum monthly duty cycle of 100,000 pages, making it suitable for reasonably heavy-duty printing.

The M712dn is ePrint enabled; HP assigns an e-mail address to the printer (which you can later customize), you can send documents to that address, and the printer will automatically print them out (as long as it's connected to the Internet).

The M712dn is the middle model of three related printers. The M712n ($1,899 direct) is the simplex version, lacking the M712dn's auto-duplexer (and its Energy Star cred). The M712xh ($2,899 direct) adds a secure hard disk and a 500-sheet paper tray in addition to all the M712dn's features.

The M712dn offers USB and Ethernet (including Gigabit Ethernet) connectivity. I tested it over the Ethernet connection with a PC running Windows Vista. As for drivers, this printer has PCL plus HP's PostScript emulation, though only the PCL driver installs by default.

HP LaserJet Enterprise 700 Printer M712dn

Print Speed
I timed the M712dn on the latest version of our business applications suite (using QualityLogic's hardware and software for timing), at 9.9 effective pages per minute (ppm), decent for its rated speed of 40 pages per minute?which should be about the speed you would get if you were to print text only. (Our test suite combines text pages, graphics pages, and pages with mixed content.) It's a respectable speed, though many mono lasers are faster?the Editors' Choice Dell B5460dn , for example, zipped through our tests at 18.7 ppm.

However, none of the mono lasers we've tested in recent years other than the M712dn can print at tabloid size. I recently timed the Editors' Choice Xerox Phaser 7100/N, a tabloid color printer rated at 30 pages per minute, at 7.9 ppm on the same tests?though it output most of the pages in color. I clocked another tabloid-sized color printer, the Dell 7130cdn at 8.3 ppm.

Output Quality
Overall output quality for the M712dn was slightly below par for a mono laser, with sub-par text, average graphics, and typical photo quality. With text there was a tendency for some letter pairs to be run together at larger sizes than usual, but even sub-par laser text is fine for typical business use. Just make a point of avoiding smaller type sizes.

In a couple of illustrations, the printer had trouble rendering distinctions between slightly different shades. Though the printer is otherwise fine for printing basic PowerPoint presentations or charts in a report, at least for in-house use, you'd have to be careful that different sections in a pie or bar chart, for instance, are distinguishable from each other.

Photo quality is suitable for printing out recognizable images from Web pages, and perhaps for photos in client newsletters, depending on how picky you and the client are. A couple of prints showed mild banding (a pattern of faint striations), most showed dithering (graininess), and there was some loss of detail in both bright and dark areas.

Running costs for the M712 are a low 1.3 cents per page, beating out the Dell 7130cdn's cost per monochrome page of 1.7 cents and the Xerox 7100/N's 2.2 cents.

As a monochrome laser, the M712dn offers good paper handling, including the ability to print at tabloid size, low running costs, and decent speed. Its output quality is good enough for typical in-house business use. The Editors' Choice Xerox Phaser 7100/N has a smaller paper capacity, higher running costs, and lacks an auto-duplexer, though one is available on the Xerox 7100/DN ($1,800). It sells at a lower price, though, its output quality is better than the M712dn's, and it can print not just monochrome but color at tabloid size.

If your business isn't too picky about output quality, doesn't require color, and you need to print in high volume, the HP LaserJet Enterprise 700 Printer M712dn could well be your preferred tabloid-sized workhorse printer. It has a relatively high monthly duty cycle, very low running costs (allowing you to recoup your relatively large investment over time), and good paper capacity; you can keep one tray loaded with tabloid-sized paper, the other with letter or legal, and the multipurpose tray free for other paper types or sizes.

Stocks climb for third straight week

Stocks rose Friday to close three straight weeks of gains on Wall Street. A?sharp increase in small-company stocks is also a sign that investors are more willing to take on risk.

A street sign for Wall Street hangs in front of the New York Stock Exchange. Stocks have benefited from record-high corporate profits.

The Dow Jones industrial average closed above 15,000 for the first time on Tuesday, then held above that milestone for the next three days. But an index of small-company?stocks?put the blue-chip gauge to shame. On Friday, the Russell 2000 closed the week up 2.2 percent, more than double the Dow's gain.

Investors are in love with small?stocks?because they stand a greater chance of surging ahead than large, global companies do if the U.S. economy continues to fare better than Europe and Asia.

"GDP growth was 2.5 percent in the first quarter ? not spectacular, but better than Europe," said Joseph Tanious, global market strategist of J.P. Morgan Funds. "Europe is sucking wind."

On Friday, the Dow, an index of 30 large-company?stocks?including global giants like IBM and Caterpillar, rose 35.87 points to close at 15,118.49 after flitting between gains and losses most of the day.

The Dow's meager gain of 0.2 percent was trumped by the 0.9 percent advance in the Russell 2000. The small-company index rose 8.90 points to 975.16. Both indexes, as well as the Standard & Poor's 500, closed at record highs. All three rose for a third straight week.

The sharp increase in small-company?stocks?is also a sign that investors are more willing to take on risk. Small?stocks?can offer investors greater returns, but they are also more volatile than large?stocks.

Dow?stocks?were held back by falling commodity prices. Exxon Mobil, Chevron and Alcoa ? all Dow members whose fortunes are tied to the prices of crude oil and other basic materials ? closed down 1 percent or more.

The price of commodities including crude oil and gold fell sharply as the dollar strengthened against other currencies, especially the Japanese yen. When the dollar rises against other currencies, it tends to weaken demand for commodities. Since commodities are priced in dollars, buyers using other currencies get less for their money when the dollar appreciates, and they respond by buying less.

Stocks?have benefited from record-high corporate profits. Nearly all companies in the S&P 500 have reported first quarter earnings. The average net income for companies in the index is expected to rise 5 percent, according to S&P Capital IQ, a research firm.

"The talk at the end of April was company earnings are slowing," said Gary Flam, who manages?stockportfolios at Bel Air Investment Advisors. "But clearly that's not been the case in the first ten days."

The S&P rose every day since the beginning of the month until Thursday, when it fell six points. On Friday it closed up 7.03 points at 1,633.70, an increase of 0.4 percent.

Flam speculates that?stocks?are rising partly because investors have shifted from fear to greed.

"The last few years, risk was defined as losing money," he said. "The last few months, it's been defined as not making money."

In another sign that investors were embracing risk, prices for ultra-safe U.S. government bonds fell, sending their yields higher. The yield on the benchmark 10-year Treasury note rose sharply, to 1.90 percent from 1.81 percent late Thursday.

The gains in the?stock?market were broad. Nine of the ten industry groups in the S&P 500 index were higher. Health care?stocks?rose the most, 1.1 percent.

The Nasdaq composite index was up 27.41 points, or 0.8 percent, to close at 3,436.58.

One dollar was worth 101.58 yen, more than the 100.54 yen it bought late Thursday. The yen has been weakening since last fall as the Bank of Japan floods the Japanese economy with cash in an effort to shake the country out of a two-decade slump.

Japanese?stocks?surged. A weaker yen is a boon to Japanese exporters of cars, electronics and other goods because they can charge cheaper prices in overseas markets. Tokyo's benchmark Nikkei 225 index jumped 2.9 percent to close at 14,607, its highest level since January 2008.

Prices for crude oil and gold fell. Crude fell 35 cents to $96.04 a barrel in New York, a loss of 0.4 percent. Gold fell $32 to $1,436 an ounce, or 2.2 percent.

Among?stocks?in the news:

? Priceline.com and chip maker Nvidia both rose about 4 percent after reporting higher earnings. Priceline jumped $27.91 to $765 and Nvidia was up 63 cents to $14.54.

? Clothing store chain Gap rose after reporting higher sales in April and predicting first-quarter earnings that were higher than financial analysts expected. Gap rose $2.18 to $40.99, or 5.6 percent.

? Dell climbed after activist investor Carl Icahn and another big investor fighting founder Michael Dell's offer to take the company private launched another broadside against the plan. In a letter to Dell's board, they proposed a deal that would keep the company public and pay shareholders cash or?stock?worth $12 a share. Dell rose 13 cents, or 1 percent, to $13.45 per share.

Surgeon: Stonewall Jackson death likely pneumonia

Historians and doctors have debated for decades what medical complications caused the death of legendary Confederate fighter Thomas J. "Stonewall" Jackson, felled by friendly fire from his troops during the Civil War.

Shot three times while returning from scouting enemy lines in the Virginia wilderness, Jackson was badly wounded in the left arm by one of the large bullets the night of May 2, 1863. Blood gushed from a severed artery. It took at least two hours to get him to a field hospital, and Jackson was dropped twice in a stretcher before his arm was amputated. He died days later at 39.

Scholars have long questioned whether it was an infection or pneumonia that killed Jackson, who gained the nickname "Stonewall" early in the war and went on to be lionized in the South and feared in the North because of his military exploits.

On Friday, the 150th anniversary of Jackson's death, a trauma surgeon with experience on the battlefield in Iraq and Afghanistan will reveal his diagnosis of Jackson's death after reinvestigating the medical record. After reviewing the 1860s files and subsequent reports, University of Maryland surgeon and professor Joseph DuBose told The Associated Press that Jackson most likely died of pneumonia.

DuBose is confirming the original diagnosis given by Jackson's personal physician, the famed Confederate doctor Hunter H. McGuire.

"You would be hard-pressed to find someone more qualified than him for the treatment of this injury and taking care of Stonewall Jackson," DuBose said. "I do defer to him in some regard. I kind of have to. He's not only the treating physician; he's also the only source of information."

McGuire's original medical notes were lost when he was captured by Union soldiers. He recreated them from memory three years later for the Richmond Medical Journal.

Pneumonia was common in the Civil War, becoming the third most fatal disease for soldiers.

Jackson is the subject of an annual conference Friday at the University of Maryland School of Medicine in Baltimore that reviews medical diagnoses of historical figures. In the past, researchers have reviewed the deaths of Alexander the Great, Edgar Allan Poe and Abraham Lincoln, among others.

DuBose is a graduate of the Virginia Military Institute, where Jackson was a professor before the Civil War. A large statue of Jackson stands near the campus barracks. So, his legacy and death were ingrained in DuBose's experience as a cadet.

Jackson was shot by soldiers from the 18th North Carolina regiment in a moment of confusion. He had led a surprise attack in the Battle of Chancellorsville in Virginia, and the Confederates drove Union forces back about three miles. Civil War historian James I. Robertson Jr. recounts that Jackson wasn't satisfied and rode out at night to review the enemy's position. When he rode back, he was shot by his own soldiers.

Then, being dropped during a frantic nighttime rescue may well have contributed to Jackson's death, DuBose found.

"If he had been dropped and had a pulmonary contusion, or bruise of the lung, it creates an area of the lung that doesn't clear secretions real well, and it can be a focus that pneumonia can start in," DuBose said. "That's probably what happened in this particular instance."

DuBose, a U.S. Air Force veteran, said pulmonary embolism ? a blockage of the major blood vessel in the lung ? still occurs in nearly 6 percent of combat casualties in Iraq and Afghanistan. It is even more common among those who have amputations, as Jackson did.

Still, the debate will continue over Jackson's death.

Dr. Philip Mackowiak, an internist who organizes the conference each year, said he differs with DuBose on the Jackson case. He reviewed the records and said he believes a recurrent pulmonary emboli destroyed Jackson's lung over time, leading to his death. The medical records don't describe Jackson coughing, as one would expect with pneumonia, Mackowiak said.

It's impossible to know for sure what killed Jackson. But DuBose said modern medicine could have saved him. Jackson's doctor didn't have the tools or knowledge to treat the complications after the shooting.

Robertson, a former Virginia Tech historian and professor who wrote Jackson's biography, said he has been persuaded that sepsis, caused by severe infection, killed Jackson, due to his chaotic rescue and unsanitary conditions. He noted, though, doctors at the time agreed Jackson had pneumonia.

"Unfortunately, medicine in the mid-19th century was still in the dark ages," he said. "Obviously, I'm not overly concerned with how he died. I'm terribly concerned that he died."

Jackson was a pivotal figure and perhaps the most esteemed soldier in the war, Robertson said. He was known for secrecy and speed to execute surprise flank attacks for Gen. Robert E. Lee's strategy.

"He was killed in what may be the high-water mark of the Confederacy," Robertson said. "You can make a case that after Chancellorsville, it's just a question of time for Lee."

New 3-D technology to treat atrial fibrillation

May 11, 2013 ? Researchers at the Intermountain Heart Institute at Intermountain Medical Center have developed a new 3-D technology that for the first time allows cardiologists the ability to see the precise source of atrial fibrillation in the heart -- a breakthrough for a condition that affects nearly three million Americans.

This new technology that maps the electronic signals of the heart three dimensionally significantly improves the chances of successfully eliminating the heart rhythm disorder with a catheter ablation procedure, according to a new study presented at the Heart Rhythm Society's National Scientific Sessions in Denver on Saturday, May 11, 2013.

Atrial fibrillation occurs when electronic signals misfire in the heart, causing an irregular, and often chaotic, heartbeat in the upper left atrium of the heart.

Symptoms of atrial fibrillation include irregular or rapid heartbeat, palpitations, lightheadedness, extreme fatigue, shortness of breath or chest pain. However, not all people with atrial fibrillation experience symptoms.

"Historically, more advanced forms of atrial fibrillation were treated by arbitrarily creating scar tissue in the upper chambers of the heart in hopes of channeling these chaotic electrical signals that were causing atrial fibrillation," said researcher John Day, MD, director of the heart rhythm specialists at the Intermountain Heart Institute at Intermountain Medical Center. "The beauty of this new technology is that it allows us for the first time to actually see three dimensionally the source of these chaotic electrical signals in the heart causing atrial fibrillation."

Previously, cardiologists were able to map the heart in 3-D to enhance navigation of catheters, but this is the first time that they've utilized 3-D imaging technology to map the heart's specific electronic signals. Armed with this information, cardiologists can now pinpoint exactly where the misfiring signals are coming from and then "zap" or ablate that specific area in the heart and dramatically improve success rates.

With this new technology, cardiologists will now be able to treat thousands of more patients who suffer from advanced forms of atrial fibrillation and were previously not felt to be good candidates for this procedure.

"The capabilities of the new technology can be compared to a symphony concert," said Jared Bunch, MD, medical director for electrophysiology research at the Intermountain Heart Institute at Intermountain Medical Center. "During the concert, you have many different instruments all playing different parts, much like the heart has many frequencies that drive the heartbeat. This novel technology allows us to pinpoint the melody of an individual instrument, display it on a 3-D map and direct the ablation process."

The research team used the new 3-D mapping technology on 49 patients between 2012 and 2013 and compared them with nearly 200 patients with similar conditions who received conventional treatment during that same time period.

About one year after catheter ablation, nearly 79% of patients who had the 3-D procedure were free of their atrial fibrillation, compared to only 47.4% of patients who underwent a standard ablation procedure alone without the 3-D method.

"This new technology allows us to find the needles in the haystack, and as we ablate these areas we typically see termination or slowing of atrial fibrillation in our patients," says Dr. Day.

All of the patients in the study had failed medications and 37 percent had received prior catheter ablations. The average age of study participants was 65.5 years old and 94 percent had persistent/chronic atrial fibrillation.

Previous research has shown that the incidence of atrial fibrillation increases with age. A report from the American Heart Association shows the median age for patients with atrial fibrillation is 66.8 years for men and 74.6 years for women.

If untreated, atrial fibrillation can lead to blood clots, stroke and heart failure. In fact, people with atrial fibrillation are five times more likely to have a stroke than people without the condition.

Intermountain Medical Center is the flagship facility for the renown Intermountain Healthcare system.

He'll want that one back

Associated Press Sports

updated 11:11 p.m. ET May 10, 2013

ST. LOUIS (AP) - Shelby Miller gave up a single to start the game then nothing else. Not a walk or a hit batter. No one even reached on an error.

Nothing.

The St. Louis Cardinals rookie was perfect after that leadoff single by Eric Young Jr., retiring 27 in a row for his first career complete game, 3-0 over the Colorado Rockies on Friday night.

"I feel really good," Miller said. "It's definitely the best game I've thrown in my life. How it finished was unbelievable. It was a great experience. Yadi (catcher Yadier Molina) was calling a great game and they were making great plays for me. It was a start I'll remember the rest of my life."

Miller (5-2) struck out Young to end it with his 13th K, tying a Cardinals rookie record.

Young felt fortunate just to reach base at all.

"It was a jam shot and I just put it in a good location," Young said. "I was just fortunate enough to find grass.

"He was working both sides of the plate, using his fastball. He had great command," Young added. "His battery mate back there is obviously one of the best game. It was a good combo for them."

Miller agreed with Young's assessment of Molina.

"I say it time and time again, what Yadi calls, I throw," Miller said. "He was calling the right thing all night. He's done a terrific job all year and he's helping me out tremendously. I'm happy he's my catcher, that's for sure."

The one-hitter was the fewest hits allowed by a Cardinals pitcher since Bud Smith tossed a no-hitter on Sept. 3, 2001, and it was the second one-hitter of the night in the major leagues. Boston's Jon Lester was perfect until he allowed a two-out double in the sixth against Toronto.

In a near-perfect performance, Miller threw 113 pitches.

"It's pretty incredible," St. Louis manager Mike Matheny said. "How he held his composure, made real good pitches all night long against a very good offense."

Miller lowered his ERA to 1.39, which is the lowest for a Cardinals pitcher in his first eight starts since Howie Pollet had a 2.09 ERA in his first eight in 1941.

Carlos Beltran hit a solo homer - his ninth - for St. Louis. Pete Kozma added an RBI single and Jon Jay a sacrifice fly for the Cardinals, who are National League-best 22-12.

Molina had two hits to extend his hitting streak to 10 games, which is the longest for a Cardinal this season.

Rockies starter Jon Garland (2-3) gave up all three runs in five innings. Garland allowed seven hits and three walks while striking out five.

Garland retired the first five batters he faced before Jay singled to center with two outs in the second. David Freese walked, and Kozma drove home Jay with a single to left.

Beltran made it 2-0 when he hit Garland's first pitch of the third inning 409 feet into the seats in right. Jay gave the Cardinals a three-run cushion with a sacrifice fly in the fifth.

NOTES: Dick Hughes and Scipio Spinks also struck out 13 for the Cardinals as rookies. ... Molina is batting .461 (18 for 39) during his hitting streak. ... Colorado has not won a series in St. Louis since sweeping four games from June 5-8, 2009. ... Jay extended his hitting streak to seven games with his second-inning single. ... Garland is 1-6 with 6.61 ERA in his career against St. Louis. ... Former Cy Young award winner Chris Carpenter took another step toward possibly returning to the mound by tossing a pain-free bullpen session. The 38-year-old's career appeared as if it may be over when it was announced in February that he was unlikely to pitch in 2013 because he was still experiencing chronic pain in his neck, shoulder and arm. Friday's bullpen session was the fourth for Carpenter, who tossed about 70 pitches.

Fast-food workers in Detroit walk off job, disrupt business

By Steve Neavling and Lisa Baertlein

(Reuters) - Hundreds of fast-food employees in Detroit walked off the job on Friday, temporarily shuttering a handful of outlets as part of a growing U.S. worker movement that is demanding higher wages for flipping burgers and operating fryers.

The protests in the Motor City - which is struggling to recover from the hollowing out of its auto manufacturing sector - marked an expansion in organized actions by fast-food workers from ubiquitous chains owned by McDonald's Corp, Burger King Worldwide and KFC, Taco Bell and Pizza Hut parent Yum Brands Inc.

Fast-food workers, who already have taken to the streets in New York, Chicago and St. Louis, are seeking to roughly double their hourly pay to $15 per hour from around minimum wage, which in Michigan is $7.40 per hour.

Organizers said more than 400 people turned out for the Detroit event, the most to date.

They also said the walk-outs forced the temporary closures of two McDonald's restaurants, a Burger King, a Subway, a Long John Silver's and a Popeyes in Detroit - a claim some chains disputed.

Outside a Burger King on 8 Mile in Detroit, employee Claudette Wilson said she's tired of poor wages, especially at a time when the fast-food industry continues to grow.

"I make minimum wage, which is what I made when I started working in fast food three years ago," the 20-year-old college student said. "I can't understand how the industry is growing but our wages aren't."

Organizers said the Detroit metro area has 53,000 fast-food jobs, which pay at or just above minimum wage.

The fast-food workforce is twice as large as that of the region's famed auto manufacturing sector and is projected to grow faster than the region's overall workforce in the coming years, organizers said.

"People can't make a living at $7.40 a hour," said Rev. Charles Williams II, a protest organizer. "Many of them have babies and children to raise, and they can't get by with these kind of wages."

Those workers face high hurdles in their fight for better pay. Low-wage, low-skill workers lack political clout and face significantly higher unemployment than college graduates.

U.S. President Barack Obama proposed raising the federal minimum wage in his State of the Union address as a way to help lift some workers out of poverty. But critics of such a move, including representatives for the nearly $200 billion U.S. fast-food industry, say it would kill jobs by burdening small businesses with higher costs.

PROTESTS, DISPUTES

At a Long John Silver's on Detroit's east side, a lone manager tended the restaurant as the presence of protesters appeared to stifle business.

A McDonald's spokeswoman told Reuters its Michigan restaurants were "open, and operating as usual". Burger King said none of its restaurants were shut down and no workers walked off the job.

Representatives from Subway, Long John Silver's and AFC Enterprises' Popeyes did not immediately respond to requests for comment.

Margaret Neal, 52, said frustration with the low wage she earns after more than a decade working at a McDonald's in Detroit prompted her to join Friday's protests.

Asked about her pay, Neal said: "You don't even want to know, I've been there 15 years. I'm still making $8.83 (an hour). That's not right."

Neal, who works full-time, says her bosses have told her she is "maxed out" at her current wage and ineligible for an increase.

The vast majority of McDonald's more than 14,000 U.S. restaurants are owned and operated by franchisees. The company said in a statement that McDonald's employees are paid competitive wages, have access to a range of benefits and opportunities for training and career advancement.

The Detroit action was put together by the Michigan Workers Organizing Committee, an independent union of fast-food workers, that is supported by community, labor and faith-based groups such as the Interfaith Coalition of Pastors, UFCW Local 876, SEIU Healthcare Michigan and Good Jobs Now.

Why customer service and support still matters | Intxt

Customer service mattersCustomer service and support is a huge part of any industry, big or small. Customers are essential to all businesses who wish to survive ? if you think that your customers are not important to you or your company, you won?t last very long in your industry. A customer decides what company they wish to do business with depending on the services the business offers and how well they treat their customers.

In the world of business it?s all about competition. If your company shows a weakness of any kind, you could lose current and potential customers to your competitors, making it hard for you to thrive in your business sector. This is not an option for you. The best way to keep your customers is to treat them like they?re royalty and show that they really mean something to the company. Having a customer service and support department who are fully trained in helping your customers and going above and beyond to make sure that they are fully satisfied with the help given.

All customers deserve to be treated with the utmost respect and should feel like their business is wanted. If a customer is unsatisfied by your customer service, they may think about taking their business elsewhere, maybe to one of your competitors. They could also mention your company in a negative way to other businesses or online which could create a bad image for you and possibly drive customers away.

If you want your company to thrive, you should make sure you stand out from the rest with amazing customer support services that your customers won?t be disappointed with. Go the extra mile with your clients and spoil them as much as you can.

Customer service and support definitely still matters ? even in the 21st century. There is no way out of it; your customers are what make your company run and they bring in a large amount of revenue, so why would you ruin that? If a client rings up asking for help, you must find a solution for them as quickly as possible so that they stay happy and loyal to your company.

There are many ways that you can keep in touch with your customers, whether it?s a quick text message mentioning discount on a service or a phone conversation helping them fix a problem they may be having. The trick is to impress them so much that all they can do is praise you, with no complaints.

Make sure your customer service department know exactly what they?re doing and are doing their job right because you could be losing current or potential customers without even realising it.

Print, Aim and Shoot: What Does a Plastic Handgun Mean for the Future of 3-D Printing?

A University of Texas at Austin law student has demonstrated to the world that any ambitious tinkerer can make a handgun almost entirely out of 3-D printed parts. Cody Wilson?s revelation is not likely to lead to an arsenal of plastic zip guns anytime soon, but it does raise a number of hairy questions about a technology that, until now, has been highly touted as central to the future of manufacturing in the U.S.

Images and video of Wilson posing with and firing his ?Liberator? handgun have made the rounds on the Internet in recent days. It?s a stark contrast to the image that 3-D printing, or ?additive manufacturing,? proponents have pursued thus far, where the world benefits from robotic prosthetics, replacement hips and other biomedical wonders manufactured layer by layer out of molten plastic or metal, as dictated by a CAD (computer-aided design) file.

Wilson?s gun consists of 15 parts assembled after being printed individually in a Stratasys Dimension SST machine out of white ABS plastic?a polymer made from the chemical compounds acrylonitrile, butadiene and styrene. Only the gun?s firing pin (a common nail) and an obligatory piece of steel embedded in the handle?so that it does not violate the Undetectable Firearms Act (pdf)?are metal. Wilson has made the design files needed to create the Liberator?that fires standard handgun rounds?available as a free download for anyone interested in replicating his work.

Wilson positions himself as a protector of civil liberties?in particular ?popular access to arms??and has founded a nonprofit called Defense Distributed to further this goal. His libertarian views are not unlike those of free, open-source software advocates or hackers who take down Web sites and pick apart popular software like Windows to prove they are not as secure as they appear?except for the small detail that he wants to empower people to make devices that can harm or kill other people. (He?s also published blueprints for 3-D printing part of an AR-15 semiautomatic rifle.)

Technically speaking, Wilson?s so-called ?Wiki Weapon? pushes the boundaries of 3-D printing capabilities, especially those of lower-end systems not able to work with anything stronger or more durable than ABS plastic. Although the Liberator currently fires only a single shot, better materials as well as improved designs and post-processing techniques might ultimately lead to a weapon that can shoot multiple rounds without breaking down.

To learn more about the potential impact of Wilson?s work on the world of 3-D printing, Scientific American spoke with Ryan Wicker, director of the University of Texas at El Paso?s W. M. Keck Center for 3-D Innovation. Wicker shared his thoughts about Wilson?s invention, the technical challenges of making a 3-D printed gun and the reality that the unbridled creativity promoted by 3-D printing was destined to take a darker turn.

[An edited transcript of the interview follows.]

What was your reaction when you learned that someone had printed nearly all of the components needed to assemble a handgun using a 3-D printer?
This story has been developing for months, if not years, so it was pretty anticlimactic. I probably first became aware of what [Wilson] has been doing when Stratasys went in and confiscated the printer they leased to him [in October. I have been hearing for years about people using 3-D printers to make parts for guns. In the evolution of 3-D printing it?s certainly natural for things like this to happen.

Are there specific challenges to making a working firearm using 3-D printed parts?
Building the parts with a high level of dimensional accuracy would be one challenge and the material performance would be another. A firearm experiences a high-energy impulse in the chamber, where the gun components start off at ambient conditions but are subjected very quickly to higher temperatures and pressures. This sudden change can compromise the structural integrity of the gun, even possibly making it explode.

What is the significance of Wilson making most of his gun parts out of ABS plastic?
ABS is an inexpensive polymer typically used by the type of 3-D printer that he used. There are plastics that are stronger, more durable and perform much better than ABS, but those higher-end materials require higher-end machines than what he had.

Why is ABS the standard plastic for lower-end systems?
ABS is just a commodity, a commonly used plastic that the automotive industry has used for years to create injection-molded parts. Different 3-D printing systems work differently, but [Wilson?s] uses an extrusion-based process that?s analogous to a hot-glue gun. ABS?s extrusion temperature [the point at which the polymer starts to deform and can be squeezed out into layers] is lower than other, more capable plastics. It doesn?t require a more expensive system that can [operate at] higher temperatures.

Why not use a more durable plastic?
Stratasys offers a more expensive plastic called Ultem, which potentially would be a better performer than ABS for this application. But you can?t print this type of high-end material using the low-end [$20,000] industrial printer that [Wilson] used. You need a high-end machine that costs anywhere between $100,000 and $400,000 to be able to use those better plastics. Although it?s not possible now, that doesn?t mean someone couldn?t develop the capability to work with better plastics on low-end systems. Other than the materials that can be used, what limitations do lower-end 3-D printers have at this time?
Another limitation is accuracy. These machines don?t have the temperature control of higher-end systems, and consequently the dimensional accuracies suffer. The more expensive industrial systems take into account how much a part will change as it goes through the process of being made. Better temperature control enables a printer to better adjust for changes in the material as it is layered, solidifies and shrinks. If you don?t take those changes into account, some layers might be farther apart, creating voids that prevent the finished product from being as strong as it could be.

All of these things can be overcome. There are lots of people working in their homes on inexpensive desktop systems [like those MakerBot produces] who are going to be geeky, experimenting and optimizing their systems. They?ll write their own code and figure out how to compensate for their equipment and materials. That?s what my students do. There is some knowledge that you have to develop to use these systems optimally.

As inventors develop this knowledge, are there concerns that more of them will experiment with 3-D printed weapons?
3-D printing is not the only enabling technology here. 3-D printers may be a little less complicated to use than [some computer numerical control (CNC) systems that manufacturers use to make tools], but you still can buy a CNC machine today and use that to build weapons. In fact, I would be much more scared of people who have expertise in machine shops [making weapons] than I would of someone using a 3-D printer.

And, even if you don?t print the parts for the weapons yourself, there?s an entire industry that makes parts on demand today using 3-D printing. You can upload your file online without even speaking with anyone and pay for it with your credit card.

How soon will higher-end 3-D printers capable of using better materials become affordable for hobbyists and inventors?
I don?t know how much the cost can come down for some high-end systems because they are big machines and they use more expensive industrial components, which limits how much the price can be reduced. And the price of high-end systems may not be the limiting factor for hobbyists because they can take a desktop system [like those made by MakerBot] and supercharge it, and there?s no technical reason you couldn?t use it to print a weapon.

How would you supercharge a desktop 3-D printer to give it that capability?
I may enclose it so that I can reach higher temperatures and work with [stronger, more durable] materials. I might also do this by modifying the printer?s heater to make the printhead hotter.

People are less likely to modify an industrial system because companies like Stratasys don?t give you access to their printer?s source code. MakerBot and other desktop printer?makers do. That means I can write my own code to change things on these lower-end systems but I can?t [change] that on a Stratasys system. Even the materials used by industrial systems are controlled. A canister of material used in a Stratasys printer even has a microchip that knows what and how much material it contains.

What impact will Wilson?s experiment have on 3-D printing?
It concerns me a little, but I think this type of project was inevitable. We would all like these technologies to be used for the benefit of society, and I believe these benefits far outweigh the risks. There are lots of wonderful examples?customized hearing aids, 3-D printed electronics and even shoes as well as [efforts to print artificial human] organs. The government will ultimately decide whether the technology should be regulated, but I see these technologies completely disrupting the way we make products, and bringing innovative, entrepreneurial manufacturing work back to the U.S. We?ve traveled too far down the road to turn back at this point. With these technologies, the future is limited only by one?s imagination. Follow Scientific American on Twitter @SciAm and @SciamBlogs.

The Loop Magazine: The long-form Loop you've been waiting for!

The Loop Magazine: The long-form Loop you've been waiting for!

I've been bitching to Jim Dalrymple of The Loop for years that, as much as I liked his and Peter Cohen's highly curated, Apple-, web-, music-, and gaming-centric link-list style, I missed their longer form pieces, the kind I remembered fondly from Macworld. Jim, of course, laughed. You might well know Jim's laugh. It's equal parts hilarious and bone-chilling. That laugh. Then, one day, he called me and said I could stop my bitching. He had a plan. He was going to start The Loop Magazine.

And now here it is, on the App Store, in Newsstand, and on my iPhone and iPad. I've been testing it out for a while , and I daresay setting new records for dumbassery in my feedback -- you don't want to hear the laugh that engenders, trust me. And it's everything you've come to expect from Jim and Peter, and more. They've both got articles in the first issue, Peter an article on the balkanization of Mac gaming, and Jim a welcome letter:

In 1994, I helped start a Web site that would later be sold to Macworld. I started publishing on the Internet because I believed it was the publishing platform of the future. Almost 20 years later, I have chosen Apple?s Newsstand for the very same reason.

The first issue of The Loop magazine features some great writers covering music, design, technology, games and Apple ? some of my favorite topics. I hope you enjoy it!

Like Marco Arment's The Magazine, however, which they credit for inspiring The Loop Magazine, Jim and Peter have also collected together some amazing collaborators, including Matt Gammell, Jodan Rudess, Ben Bajarin, Michael Simmons, and Holly Winewell, aka Brenda Singer. And that's just the first issue.

Also like The Magazine, the Loop Magazine will publish new issues every two weeks, and the subscription will run $1.99 a month. Unlike Arment, a noted developer who coded his own app with design help from Pacific Helm, Jim and Peter are staying focused on their journalistic strengths here, and handed off the development heavy lifting to Jamie Smyth and Daniel Genser at TypeEngine. The results are pretty damn good.

The Loop Magazine is clean, elegant, and fast. It uses the familiar menu button and sidebar layout (though eschews the hamburger and basement design for an arrow and slide-over panel). A Share Sheet lets you send links for the various articles via Mail, Messages, Twitter, Facebook, App.net, or copy them to the clipboard. There aren't any The Magazine-style popovers, at least not yet, or integration with read-later services like Instapaper or Pocket. The former probably isn't necessary. The latter would be nice in a future update.

The Loop Magazine table of contents, article view, and share sheet

A great app experience is one thing, though. Content is what's going to make or break any publication, print, online, or in-app. The Loop Magazine is off to a great start in that regard, and Jim and Peter have been around the industry long enough, and have just exactly the kind of connections necessary, to keep fielding great issues for months and years to come.

Marco Arment's The Magazine has evolved into its own, unique voice. There's room for lots of those, and I'm thrilled, as a reader, we're getting more of them, starting with The Loop. There's a free trial subscription, so check it out and let me know what you think.

Note: Peter Cohen, who co-founded The Loop with Jim, also works here on iMore. Jim told me about the Loop Magazine long before Peter joined us at iMore, however, and I haven't discussed this review with either of them. Still, I'd recommend checking out other reviews to make sure you get as well-rounded an opinion of The Loop Magazine as possible.

Hi everyone,

A lot of you around here will already know that I'm a web designer. I've often thought that I could easily come up with two or three simple principals that would have saved me a lot of struggling and heartache if I'd had known them when I first started out. I'm an experienced web developer now, and will always go out of my way to impart wisdom where I can.

One thing I've never done is manage an online store for myself. I'm soon to opening an store which will sell wines from the Swan Valley (many prolific vineyards recognized globally by wine aficionados) to people locally and all over the world.

I was wondering if anyone has any short and sweet tips for me that will get me going on the right track? I think I have a fairly good idea how to run the thing, but you never know what you haven't thought of until someone tells you

I don't expect you to spend ages writing an essay for me, just anything that pops into mind that you wish you'd known when you started out.

Thanks everyone,
Martin - The Web Guy

Link between intimate partner violence and depression

May 7, 2013 ? Not only are women who have experienced violence from their partner (intimate partner violence) at higher risk of becoming depressed, but women who are depressed may also be at increased risk of experiencing intimate partner violence, according to a study by international researchers published in this week's PLOS Medicine.

Furthermore, there may also be a link between intimate partner violence and subsequent suicide among women, but little evidence to support a similar finding in men.

The researchers led by Karen Devries from the London School of Hygiene & Tropical Medicine, reached these conclusions by reviewing published studies that followed up individuals over a period of time (longitudinal studies) and examined intimate partner violence, depression, and suicide attempts.

Over 36 000 people from high- and middle-income countries were included in the review and in a further analysis, the authors found that in women, experience of intimate partner violence nearly doubled the odds of subsequent depression. However, they also found the reverse; that is, women with depression had nearly double the odds of subsequently experiencing intimate partner violence.

For men, the authors found some evidence of a link between intimate partner violence and later depression but no evidence for a link between depressive symptoms and subsequent intimate partner violence.

The authors say: "Our findings suggest that interventions to prevent violence need to be explored for their efficacy in reducing different forms of depression. Similarly, for women already receiving mental health treatments or presenting with symptoms of depression, attention must be paid to experiences of violence and risk of future violence."

They continue: "Further research is needed to explore why having depressive symptoms can lead to incident violence -- it may be that young women with depressive symptoms are predisposed to choose partners who use violence."

The authors add: "It is clear that addressing the burden of untreated mental disorders in a population could have substantial effects on the prevalence of violence."

In an accompanying Perspective, Alexander Tsai from Harvard Medical School in the US (uninvolved in the study) says: "The review reveals major gaps in research on intimate partner violence and depression, including lack of adjustment for childhood sexual abuse or other trauma."

Tsai continues: "A life course perspective, which is missing from much of the research on determinants of violence in general, would greatly enrich the field by helping intervention programs better address histories of child abuse and/or family violence in identifying targets for secondary prevention."

Asian shares tick higher, weak durable orders stall dollar

By Chikako Mogi

TOKYO (Reuters) - Asian shares edged higher on Thursday, supported by views that a run of weak global economic data will encourage major central banks to keep or deepen their monetary stimulus, though dismal U.S. durable goods orders for March weighed on the dollar.

Oil prices, copper and gold recovered, also helping to improve sentiment towards risk assets.

"Despite the weaker data, equity markets and risk assets look generally well supported, with Q1 earnings releases and ongoing policy stimulus helping to maintain the positive tone," said Mitul Kotecha, strategist at Credit Agricole in a note.

MSCI's broadest index of Asia-Pacific shares outside Japan <.miapj0000pus> was up 0.3 percent, with South Korean shares <.ks11> gaining 0.5 percent as metals and chemicals rebounded on higher gold and oil prices.

Hong Kong shares <.hsi> added 0.5 percent. A 0.3 percent drop in Shanghai <.ssec> capped the rise in the pan-Asian index.

"Fund managers talk of rebalancing their portfolios away from being too tech-heavy. Oil and chemicals are attractive because shares are very cheap," said Yoo Young-kook of Seoul shares.

Early on Thursday, South Korea said its economy grew a seasonally adjusted 0.9 percent in the January-March period from the previous quarter, the fastest in two years and far above market expectations. The surprising growth dented expectations for a rate cut by the Bank of Korea.

Otherwise recent disappointing data in the United States, Europe and China has fueled expectations for a global slowdown during the spring for a third straight year.

Global equities rose on Wednesday on strong corporate earnings and speculation that the European Central Bank will cut interest rates next week.

The growing expectations of an ECB rate cut helped offset growth concerns highlighted by U.S. durable goods posting their biggest drop in seven months in March and the Ifo survey showing that German business sentiment in April fell further than the most bearish forecasts.

Despite the rate cut speculation and weak euro zone data, the euro was up 0.3 percent to $1.3050 and away from Wednesday's three-week low of $1.2954. The resilience of the single currency partly stemmed from falling yields in highly-indebted Italy and Spain and hopes Italy will break its political deadlock two months after an inconclusive election.

Adrian Foster, head of financial markets research for Asia-Pacific at Rabobank International in Hong Kong, said the main factor behind an improved tone was the recent rally in the peripheral European government bond market which reflected waning fears about an euro zone implosion.

"We've already been seeing the market evolve from the European crisis to focus more on specific issues in a country or events," he said, adding that it was a positive development that investors were reverting to behavior seen before the financial crisis.

Japan's Nikkei stock average <.n225> hit its highest since June 2008 earlier on Wednesday, as a weakening yen bolstered expectations for improved corporate earnings. The index was last up 0.1 percent.

Most observers have welcomed an April 4 decision by the Bank of Japan to embark on a radical monetary expansion campaign That could help the global economy. The BOJ plans to inject about $1.4 trillion into the world's third-largest economy in less than two years in an effort to end two decades of stagnation.

"The weaker yen is having a positive effect on companies' earnings, which in turn is lifting stocks," he said. "For now, we see this trend continuing," said Hiroichi Nishi, an assistant general manager at SMBC Nikko Securities.

Japan's capital flows data showed on Thursday that Japanese investors remained net sellers of foreign bonds, in line with comments from big life insurers that they remain cautious about immediately shifting their money out of Japanese government bonds into foreign bonds.

Japanese investors sold a net 862.6 billion yen of foreign bonds in the week to April 20, while foreign investors turned net sellers of Japanese shares.

The dollar was down 0.1 percent at 99.37 yen, still within sight of testing the symbolic 100 yen level which many traders say is just a matter of time. Against a basket of key currencies, the dollar <.dxy> was down 0.4 percent.

The U.S. government's report on gross domestic product due on Friday is expected to show the economy grew at a 3.0 percent annual rate in the first quarter, rebounding from a 0.4 percent gain in the final three months of 2012.

For the current quarter, economists are looking for expansion of only around 1.5 percent or so.

On the corporate front, of the 174 companies in the S&P 500 index that already have reported results, 68.4 percent have exceeded analysts' expectations, according to Thomson Reuters data through Wednesday morning.

U.S. crude rose 0.5 percent to $91.87. a barrel and Brent was up 0.5 percent at $102.20.

Spot gold jumped 1.1 percent to $1,445.45 an ounce while London copper rose 0.4 percent to $7,060 a metric ton (1.1023 tons).

Rethinking early atmospheric oxygen: Possibility of more dynamic biological oxygen cycle on early Earth than previously supposed

Apr. 24, 2013 ? A research team of biogeochemists at the University of California, Riverside has provided a new view on the relationship between the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth history, and its relationship to the sulfur cycle.

A general consensus exists that appreciable oxygen first accumulated in Earth's atmosphere around 2.4 to 2.3 billion years ago. Though this paradigm is built upon a wide range of geological and geochemical observations, the famous "smoking gun" for what has come to be known as the "Great Oxidation Event" (GOE) comes from the disappearance of anomalous fractionations in rare sulfur isotopes.

"These isotope fractionations, often referred to as 'mass-independent fractionations,' or 'MIF' signals, require both the destruction of sulfur dioxide by ultraviolet energy from the sun in an atmosphere without ozone and very low atmospheric oxygen levels in order to be transported and deposited in marine sediments," said Christopher T. Reinhard, the lead author of the research paper and a former UC Riverside graduate student. "As a result, their presence in ancient rocks is interpreted to reflect vanishingly low atmospheric oxygen levels continuously for the first ~2 billion years of Earth's history."

However, diverse types of data are emerging that point to the presence of atmospheric oxygen, and, by inference, the early emergence of oxygenic photosynthesis hundreds of millions of years before these MIF signals disappear from the rock record. These observations motivated Reinhard and colleagues to explore the possible conditions under which inherited MIF signatures may have persisted in the rock record long after oxygen accumulated in the atmosphere.

Using a simple quantitative model describing how sulfur and its isotopes cycle through Earth's crust, the researchers discovered that under certain conditions these MIF signatures can persist within the ocean and marine sediments long after O2 increases in the atmosphere. Simply put, the weathering of rocks on the continents can transfer the MIF signal to the oceans and their sediments long after production of this fingerprint has ceased in an oxygenated atmosphere.

"This lag would blur our ability to date the timing of the GOE and would allow for dynamic rising and falling oxygen levels during a protracted transition from an atmosphere without oxygen to one rich in this life-giving gas," Reinhard said.

Study results appear in Nature's advanced online publication on April 24.

Reinhard explained that once MIF signals formed in an oxygen-poor atmosphere are captured in pyrite and other minerals in sedimentary rocks, they are recycled when those rocks are later uplifted as mountain ranges and the pyrite is oxidized.

"Under certain conditions, this will create a sort of 'memory effect' of these MIF signatures, providing a decoupling in time between the burial of MIF in sediments and oxygen accumulation at Earth's surface," he said.

According to the researchers, the key here is burying a distinct MIF signal in deep sea sediments, which are then subducted and removed from Earth's surface.

"This would create a complementary signal in minerals that are weathered and delivered to the oceans, something that we actually see evidence of in the rock record," said Noah Planavsky, the second author of the research paper and a former UC Riverside graduate student now at Caltech. "This signal can then be perpetuated through time without the need to generate it within the atmosphere contemporaneously."

Reinhard, now a postdoctoral fellow at Caltech and soon to be an assistant professor at Georgia Institute of Technology, explained that although the researchers' new model provides a plausible mechanism for reconciling recent conflicting data, this can only occur when certain key conditions are met -- and these conditions are likely to have changed through time during Earth's long early history.

"There is obviously much further work to do, but we hope that our model is one step toward a more integrated view of how Earth's crust, mantle and atmosphere interact in the global sulfur cycle," he said.

Timothy W. Lyons, a professor of biogeochemistry at UCR and the principal investigator of the research project noted that this is a fundamentally new and potentially very important way of looking at the sulfur isotope record and its relationship to biospheric oxygenation.

"The message is that sulfur isotope records, when viewed through the filter of sedimentary recycling, may challenge efforts to precisely date the GOE and its relationship to early life, while opening the door to the wonderful unknowns we should expect and embrace," he said.
