Shortcuts: The Meaning in a Drawer Full of Old Family Snapshots

A resident found photos as she sifted the debris of a house destroyed by Hurricane Sandy in Union Beach, N.J.

I WASN’T going to write about Hurricane Sandy. I was going to write about the changing nature of photographs and our relationship to them in this digital age.

Doug Mills/The New York Times

Picture-taking is now mainly digital, making prints of photos uncommon.

But as I began my research, I came across a Facebook page where lost photos from the storm were posted. Called “Union Beach — Photos and Misplaced Items,” the page shows photos of newborns and birthday parties, weddings and family gatherings.

Starting the morning after the storm devastated her community of Union Beach, N.J., Jeanette Van Houten and her niece have collected over a thousand photos and some photo albums. She is making it her mission to scan and post to Facebook as many as possible, including those turned into the fire department, police station and borough hall.

In addition, she was handed a drawerful of over a thousand family photos that must have been wrenched from a dresser.

About 60 photos have been claimed so far, and some professionals have offered to restore damaged photos free.

“These photos were passed down through families and they survived Sandy, even if the structures they were in didn’t,” Ms. Van Houten said. “They tell our story.”

With the Facebook page, Ms. Van Houten uses newer technology to help people reconnect with their old-fashioned snapshots. And seeing the photographs of mundane scenes and milestones on Facebook, along with the grateful comments from people who got back a bit of their lives, reminded me of both the fragility and strength of photos and their continuing importance in our lives. Judith Dupré, author of “Monuments: America’s History in Art and Memory” (Random House, 2007), and other books, teaches a class at her local library in Mamaroneck, N.Y., called “Stories from My Life,” for older residents. They use photos and stories to write about their lives.

“They bring in a basketful of photos,” Ms. Dupré said. “Each one of these photos contains a story — they’re like a key that opens the door to a life.”

And a printed photo “is a different species than a digital photo,” she said. “I don’t think anyone’s figured out the place of digital photos in terms of memory keeping.”

When an elderly aunt of hers died and left behind lots of photographs, Ms. Dupré said the family took them to the memorial service.

“We had a table and people could select and take what they wanted,” she said. “It was a very moving part of the memorial.”

Of course, even prints can lose their meaning and poignancy through the generations.

And in some cases, as with Hurricane Sandy, photos may be safer in cyberspace than in an album on a bookshelf — as long as you remember to upload them to a site like Flickr, Shutterfly, Snapfish or countless other photo sites available. (And make sure you know how long a site will keep your photos. Some, for example, require you to show some activity at least once a year.) That way, if you lose your hard drive, you don’t lose your photos.

But Ms. Dupré said she worried that photos that existed only online somewhere might die with the photographer.

“I don’t even know what my parents have in terms of digital photography,” she said. She said she put the password to her photos safely away with her will and other documents, so her children can access them.

Now I’m not trying to say that the old-fashioned way is the only way. Photography has constantly evolved. The Brownie camera, first sold by Kodak for $1 in 1900, radicalized photography by making it available to just about everyone.

But, and I know this largely a generational thing, I can’t help but wonder about the ubiquity of the cellphone photo. As Ms. Dupré said, “The infinite number of digital photos that can be taken has devalued the single image and made one-of-a-kind prints that much more precious.”

Hurt by Rivals From Asia, Dell Profit Falls 47%

SAN FRANCISCO (Reuters) — Dell’s third-quarter profit fell 47 percent, the company said on Thursday, hurt by lower PC sales and weaker demand from large corporations. But Dell said it expected revenue to grow as much as 5 percent in the current quarter compared with sales in the previous one.

The company, once the world’s top PC maker and a pioneer in computer supply chain management, is struggling to defend its market share against Asian rivals like Lenovo. It is trying to bolster growth by focusing on products and services to corporations.

The company, founded by its chief executive, Michael Dell, said that it saw “the challenging global macroeconomic environment continuing in the fourth quarter.”

Net income was $475 million, or 27 cents a share, compared with $893 million, or 49 cents a share, in the period a year earlier. Excluding certain items, it earned 39 cents a share, compared with an average forecast of 40 cents.

Revenue fell 11 percent, to $13.7 billion, slightly less than the average analyst estimate of $13.89 billion, according to Thomson Reuters.

Dell’s chief financial officer, Brian T. Gladden, said in an interview that corporate customers continued to postpone technology spending.

“It’s not clear what’s going to cause them to increase their spending in the short term, given the uncertainty in the economy,” he said.

Dell’s enterprise solutions revenue rose 3 percent to $4.8 billion, while server and networking revenue climbed 11 percent. In contrast, consumer revenue plummeted 23 percent to $2.5 billion, underscoring the plight of the broader PC market. And sales to large corporations declined 8 percent to $4.2 billion.

The consumer market is improving with the introduction of the Windows 8 operating system from Microsoft, which has been designed with touch-screen devices and Internet-based computing in mind, Mr. Gladden said.

Part of the spending weakness among corporate customers comes from worry over early next year, when trillions of dollars in tax increases and automatic spending cuts will begin to go into force unless lawmakers agree on legislation to reduce the budget deficit, Mr. Gladden said.

The cuts could take a toll on consumer and government spending and cause the economy to stall.

“I would tell you that the behavior we are seeing from our customers today is actually driven by that uncertainty,” Mr. Gladden said. “It’s not like it’s all going to happen overnight. It’s affecting our business today.”

Dell is ensuring that it has access to cash in case there is no Congressional action.

“I would say there are several things we are doing from a planning standpoint,” Mr. Gladden said, “to ensure that we are in a position to have appropriate access to liquidity.” He said Dell was making sure it would have access to lines of credit and commercial paper.

Dell shares fell around 2 percent in late trading from their close of $9.56. The shares initially rose after the release of the results.

In BP Indictments, U.S. Shifts to Hold Individuals Accountable

HOUSTON — Donald J. Vidrine and Robert Kaluza were the two BP supervisors on board the Deepwater Horizon rig who made the last critical decisions before it exploded. David Rainey was a celebrated BP deepwater explorer who testified to members of Congress about how many barrels of oil were spewing daily in the offshore disaster.

Mr. Vidrine, 65, of Lafayette, La., and Mr. Kaluza, 62, of Henderson, Nev., were indicted on Thursday on manslaughter charges in the deaths of 11 fellow workers; Mr. Rainey, 58, of Houston, was accused of making false estimates and charged with obstruction of Congress. They are the faces of a renewed effort by the Justice Department to hold executives accountable for their actions. While their lawyers said the men were scapegoats, Attorney General Eric H. Holder Jr. said at a news conference, “I hope that this sends a clear message to those who would engage in this kind of reckless and wanton conduct.”

The defense lawyers were adamant that their clients would contest the charges, and prosecutors said that the federal investigations were continuing.

Legal scholars said that by charging individuals, the government was signaling a return to the practice of prosecuting officers and managers, and not just their companies, in industrial accidents, which was more common in the 1980s and 1990s.

“If senior managers cut corners, or if they make decisions that put people in harm’s way, then the criminal law is appropriate,” said Jane Barrett, a University of Maryland law professor and former federal prosecutor.

She noted that it was unusual for the Justice Department to prosecute individual corporate officers in recent years, including in the 2005 BP Texas City refinery explosion that killed 15 workers, where only the company was fined.

BP said on Thursday it would pay $4.5 billion in fines and other payments, and the corporation pleaded guilty to 14 criminal charges in connection with spill. The $1.26 billion in criminal fines was the highest since Pfizer in 2009 paid $1.3 billion for illegally marketing an arthritis medication.

The crew was drilling 5,000 feet under the sea floor 41 miles off the Louisiana coast in April 2010 when they lost control of the well during its completion. They tested the pressure of the well, but misinterpreted the test results and underestimated the pressure exerted by the flow of oil or gas up the well. Had the results been properly interpreted, operations would have ceased.

Mr. Vidrine and Mr. Kaluza were negligent in their reading of the kicks of gas popping up from the well that should have suggested that the Deepwater Horizon crew was fast losing control of the ill-fated Macondo well, according to their indictment, and they failed to act or even communicate with their superiors. “Despite these ongoing, glaring indications on the drill pipe that the well was not secure, defendants Kaluza and Vidrine again failed to phone engineers onshore to alert them to the problem, and failed to investigate any further,” the indictment said.

The indictment said they neglected to account for abnormal pressure test results on the well that indicated problems, accepting “illogical” explanations from members of the crew, which caused the “blowout of the well to later occur.”

In a statement, Mr. Kaluza’s lawyers said: “No one should take any satisfaction in this indictment of an innocent man. This is not justice.”

Bob Habans, a lawyer for Mr. Vidrine, called the charges “a miscarriage of justice.”

“We cannot begin to explain or understand the misguided effort of the United States attorney and the Department of Justice to blame Don Vidrine and Bob Kaluza, the other well site leader, for this terrible tragedy.”

Several government and independent reports over the last two years have pointed to sloppy cement jobs in completing the well or the poor design of the well itself as major reasons for the spill. But none of the three was indicted in connection with those problems.

Mr. Rainey was a far more senior executive, one who was known around Houston and the oil world as perhaps the most knowledgeable authority on Gulf oil and gas deposits. According to his indictment, Mr. Rainey obstructed Congressional inquiries and made false statements by underestimating the flow rate to 5,000 barrels a day even as millions were gushing into the Gulf.

Recipes for Health: Baked Acorn Squash With Wild Rice — Recipes for Health

Andrew Scrivani for The New York Times

The filling here is a Greco-Italian fusion, with a little American (wild rice) thrown in. I’m usually not a fusion sort of cook, but I wanted something creamy like risotto to fill these squash. Look for small acorn squash so that each person can have one. They’ll be like miniature vegetarian (or vegan) turkeys.

6 small acorn squash

1 bunch kale or 1 10-ounce package stemmed and washed kale, stems picked out and discarded

1 cup cooked wild rice (1/3 cup uncooked)*

1 quart vegetable stock

2 tablespoons extra virgin olive oil

1/2 cup minced onion

Salt to taste

2/3 cup arborio rice

1 plump garlic clove, minced

1/2 cup dry white wine, like pinot grigio or sauvignon blanc

1/4 cup chopped fresh dill

1/4 cup chopped flat-leaf parsley Freshly ground pepper to taste

1/4 to 1/2 cup freshly grated Parmesan cheese (1 to 2 ounces) (optional)

Cayenne or freshly grated nutmeg to taste (optional)

1. Heat the oven to 425 degrees. Line a baking sheet with foil and brush the foil with olive oil. Place the squash in the oven and bake 30 minutes. Each squash should be intact but beginning to give on the side it’s resting on, and soft enough to cut through. Remove from the oven and let sit for 15 minutes, until the squash has cooled slightly. Then, resting a squash on the slightly flattened side that it was sitting on in the oven, cut away the top third. You will be putting the top “cap” back on once the squash is filled, so cut it off in one neat slice. Scrape out the seeds and membranes from both pieces and set aside. Repeat for the remaining squash. Turn the oven heat down to 350 degrees. Oil a baking dish or sheet pan that can accommodate all of the squash.

2. Meanwhile, blanch the kale in a large pot of salted boiling water for 2 to 4 minutes, until just tender. Transfer to a bowl of cold water, drain and squeeze out excess water. Chop medium-fine and set aside. Cook the wild rice, following the directions below, and set aside.

3. Put the stock into a saucepan and bring it to a simmer over low heat, with a ladle nearby. Heat 1 tablespoon of the olive oil over medium heat in a wide, heavy nonstick saucepan or skillet. Add the onion and a generous pinch of salt, and cook gently until it is just tender, 3 to 5 minutes.

4. Add the arborio rice and garlic and stir until the grains separate and begin to crackle. Add the wine and stir until it has been absorbed. Begin adding the simmering stock, a couple of ladlefuls (about 1/2 cup) at a time. The stock should just cover the rice, and should be bubbling, not too slowly but not too quickly. Cook, stirring often, until it is just about absorbed. Add another ladleful or two of the stock and continue to cook in this fashion, adding more stock and stirring when the rice is almost dry. You do not have to stir constantly, but stir often. Continue to add stock and stir until the rice is almost tender, about 20 minutes. The rice should still be a little chewy. Add another ladleful of stock and stir in the kale, wild rice and herbs. Stir together until the stock is just about absorbed, about 5 minutes, and add another ladleful of stock. Remove from the heat. Add pepper, taste and adjust seasonings. Stir in the remaining olive oil and the Parmesan if using.

5. Season the surface of the acorn squash with salt, pepper and nutmeg or cayenne (if desired). Fill the hollowed-out squash with the risotto. Place the tops back on the squash and put them in the baking dish or on the sheet pan.

6. Bake 40 minutes, or until the squash is tender all the way through when pierced with a knife.

* To cook the wild rice, bring 2 cups of the stock or water to boil in a medium saucepan. Add salt to taste and the wild rice. When the water returns to the boil, reduce the heat, cover and simmer 40 to 45 minutes, until the rice is tender and has begun to splay. Drain and transfer the rice to a large bowl.

Yield: 6 to 8 generous servings

Advance preparation: The risotto can be made a day ahead, but you will want to heat it and add a little more stock to get the creaminess that will be lost overnight.

Attacks Resume After Israeli Assault Kills Hamas Leader

KIRYAT MALACHI, Israel — Israel and Hamas widened their increasingly deadly conflict over Gaza on Thursday, as a militant rocket killed three civilians in an apartment block in this small southern town. The deaths were likely to lead Israel to intensify its military offensive on Gaza, now in its second day of airstrikes.

In Gaza, the Palestinian death toll rose to 11 as Israel struck what the military described as medium- and long-range rocket and infrastructure sites and rocket-launching squads. The military said it had dispersed leaflets over Gaza warning residents to stay away from Hamas operatives and facilities, suggesting that more was to come.

The regional perils of the situation sharpened, meanwhile, as President Mohamed Morsi of Egypt warned on Thursday that his country stood by the Palestinians against what he termed Israeli aggression, echoing similar condemnation on Wednesday.

“The Egyptian people, the Egyptian leadership, the Egyptian government, and all of Egypt is standing with all its resources to stop this assault, to prevent the killing and the bloodshed of Palestinians,” Mr. Morsi said in nationally televised remarks before a crisis meeting of senior ministers. He also instructed his prime minister to lead a delegation to Gaza on Friday and said he had contacted President Obama to discuss strategies to “stop these acts and doings and the bloodshed and aggression.”

In language that reflected the upheaval in the political dynamics of the Middle East since the overthrow of Hosni Mubarak last year, Mr. Morsi said: “Israelis must realize that we don’t accept this aggression and it could only lead to instability in the region and has a major negative impact on stability and security in the region.”

The thrust of Mr. Morsi’s words seemed confined to diplomatic maneuvers, including calls to the United Nations secretary general, Ban Ki-moon, the head of the Arab League and President Obama.

The 120-nation Nonalignmed Movement, the biggest bloc at the United Nations, added its condemnation of the Gaza airstrikes in a statement released by Iran, the group’s rotating president and one of Israel’s most ardent foes. “Israel, the occupying power, is, once more, escalating its military campaign against the Palestinian people, particularly in the Gaza Strip,” the group’s coordinating bureau said in the statement. The group made no mention of the Palestinian rocket fire but condemned what it called “this act of aggression by the Israelis and their resort to force against the defenseless people” and demanded “decisive action by the U.N. Security Council.”

In his conversation with Mr. Obama, Mr. Morsi said, he “clarified Egypt’s role and Egypt’s position; our care for the relations with the United States of America and the world; and at the same time our complete rejection of this assault and our rejection of these actions, of the bloodshed, and of the siege on Palestinians and their suffering.”

Mr. Obama had agreed to speak with Israeli leaders, Mr. Morsi said.

The Thursday’ deaths in Kiryat Malachi were the first casualties on the Israeli side since Israel launched its assault on Gaza, the most ferocious in four years, in response to persistent Palestinian rocket fire.

Southern Israel has been struck by more than 750 rockets fired from Gaza this year that have hit homes and caused injuries. On Thursday, a rocket smashed into the top floor of an apartment building in Kiryat Malachi, about 15 miles north of Gaza. Two men and one woman were killed, according to witnesses at the scene. A baby was among the injured and several Israelis were hospitalized with shrapnel wounds after rockets hit other southern cities and towns, they said.The apartment house was close to a field in a blue-collar neighborhood and the rocket tore open top-floor apartments, leaving twisted metal window frames and bloodstains.

Nava Chayoun, 40, who lives on the second floor, said her husband, Yitzhak, ran up the stairs immediately after the rocket struck and saw the body of a woman on the floor. He rescued two children from the same apartment and afterward, she said, she and her family “read psalms.”

Isabel Kershner reported from Kiryat Malachi, Israel, and Fares Akram from Gaza. Reporting was contributed by Rina Castelnuovo from Kiryat Malachi; Mayy El Sheikh and David D. Kirkpatrick from Cairo; Gabby Sobelman from Jerusalem; Rick Gladstone from New York; and Alan Cowell from Paris.

App Smart: News360, Edge Extended, Need for Speed and Other Great Android Apps

Tablets are changing computing, there’s no doubt. I realized this when I saw my 2-year-old son pick up an iPad and master its basic controls, including discovering a child’s app, in about half an hour. The iPad led the way into this brave new world more or less alone at first. It has taken until now for the sheer pressure of innovation inside Apple’s rivals to lead to some great Android-based tablets finally making a mark.

The Need for Speed Most Wanted app for Android.

The Autumn Tree Live Wallpaper app lets you select different trees and watch their leaves descend.

A "tiled" news item display on News360.

If you’re a new owner of one of these, you’ll be happy to know that there’s many an app that will simultaneously thrill you, inform you and welcome you into the world of tablet computing.

For a great news experience, the free app News360 has to be one of the better news-aggregating ones I’ve seen on any platform. When you first open the app, you are presented with a long list of topics that it can aggregate for your convenience into different categories, from arts through science to zombies.

The app uses this profile to grab news from the Web and present it to you within its elegant interface. This is dominated by picture-based “tiles” for each news article the app collects. Each tile tells you the appropriate category, where the news item came from and when. Tapping on one of these tiles takes you to a new page that contains a screen grab of the original online source, alongside the text the app has collected from the article.

The pleasure of News360 is that you can either satisfy your curiosity by tapping on a link to read the original article or decide you have learned enough and navigate on. You can also mark the article as interesting, save it for reading offline — perhaps on a commute — or share it on a social network. These controls are also accessible from the initial “tiles” screen, where you flip over an article’s tile to see the controls. The flip is accompanied by a very pleasing animation. It’s just a little graphical touch, but small details like this make an app great fun.

Part of the fun of having a new tablet is showing off its graphical prowess. Games are a great way to do this. I’ve had immense fun with Edge Extended (about $3 on Google Play). In this game, you play a multicolored cube that you roll around a blocky terrain to collect targets. You swipe your finger on the screen to make the cube flop onto its faces to move. There are all the classic elements of collecting points, avoiding pitfalls, activating switches and so on. But despite its graphical simplicity, the app is swift-paced and very satisfying; it even gave me that sensation of falling from a height in some of its trickier parts.

If you really want to impress people with your tablet’s screen, then you’ll probably get a kick out of a game like Need for Speed Most Wanted ($7 on Google play). It’s a racing game that uses motion to control steering and simple tap controls to brake, slide the car in a drift or turn on a nitrous turbo boost. True to the “Most Wanted” title, you race on regular roads, not racetracks, and can get in trouble with the police. This app has all the typical racing fun, along with the ability to earn points that unlock better cars and so on. But the standout feature is the attractiveness of the graphics, and the image rendering even includes reflections of passing buildings in puddles. It’s really eye-popping, and it even works on a diminutive tablet like the Nexus 7.

If racing’s not your thing, you may like SoulCraft THD instead. In this hack-and-slash role-playing game, you control your character from above as it fights its way through a fantasy landscape of dungeons and cities. As on a standard computer action game, you can earn spells and improve your character’s powers.

The game is “freemium” so it’s free to download and play, but you have to make in-game purchases with real money to advance quickly. The graphics are slick, but don’t expect the kind of detailed rendering you would see on a gaming PC.

If you want to make your pals who own iPads jealous, turn on an animated background. This shows off the computing power of your tablet and Android’s skills, too.

Right now my tablet is rocking the seasonal Autumn Tree Live Wallpaper, which is $1. You can control all sorts of aspects of the app, including what type of trees wave their autumnal leaves in the wind, and it’s delightful. It’s also something that a stock iPad absolutely can’t do.

Have fun, but here’s a big reminder for you: Not all Android tablets will play nicely with all tablet apps, and some features depend on installing the latest edition of the operating system.

Quick Calls

Fresh and free on Android and iOS is a highly unusual “experimental” game, Curiosity. It’s a cube with faces made of millions of smaller cubes. Players all around the world hack away at these by tapping on their devices. A single prize is hidden inside an unknown number of layers. It’s weirdly fun to play ... One of the earliest and slickest apps for Windows 8/RT devices is the official Wikipedia app (free), which shows the online encyclopedia in its most elegant, graphical format yet.

Obama Meets C.E.O.’s as Fiscal Reckoning Nears

Luke Sharrett for The New York Times

Ursula M. Burns, chief of Xerox, said the president discussed few specifics of a potential agreement but emphasized that “we cannot go over the fiscal cliff.”

WASHINGTON — President Obama extended an olive branch to business leaders Wednesday, seeking their support as he prepared to negotiate with Congressional Republicans over the fiscal impasse in Washington.

If Congress and the president cannot reach a deal to reduce the deficit by January, more than $600 billion in tax increases and spending cuts will go into effect immediately — a prospect many chief executives and others warn could tip the economy back into recession.

Even so, Mr. Obama has some fence-mending to do before he can count on any serious backing from the business community.

“The president brought up that he hadn’t always had the best relationship with business, and he didn’t think he deserved that, but he understood that’s where things were and wanted it to be better,” said David M. Cote, chief executive of Honeywell. He was one of a dozen corporate leaders invited to meet Mr. Obama at the White House for 90 minutes Wednesday afternoon, after the president’s first news conference since the election.

While Mr. Obama did not present a detailed plan at Wednesday’s meeting or reveal what he would propose in terms of new corporate taxes, he strongly reiterated that he would not allow tax cuts for the middle class to expire. The president, according to attendees and aides, said he was committed to a balanced approach of reductions in entitlements and other government spending and increases in revenue.

With time running out, many people expect the president and Republican leaders in Congress to come up with a short-term compromise that prevents the full slate of tax increases and spending cuts from hitting in January. That would give both sides more time to come up with a far-reaching deal on entitlement spending, even as they work on a broad tax overhaul later next year.

One corporate official briefed on the meeting said that the chief executives came away with a sense that Mr. Obama was poised to present a more formal proposal in the next few days, but that he did not press them for support on particular policies. “It was more of a back and forth,” he said.

The chief executives from some of the country’s biggest and best-known companies, including Procter & Gamble and I.B.M., were not unified on everything, according to one who was interviewed after the meeting.

Many of the executives who described the meeting would speak only on condition of anonymity.

The outreach to business comes as both the White House and corporate America maneuver ahead of the year-end deadline, as well as the beginning of Mr. Obama’s second term. Many executives were put off by what they saw as antibusiness rhetoric coming from the White House in his first term, and many also oppose tax increases on the rich that Mr. Obama favors but would hit them personally.

Both sides have plenty to gain from a better relationship. Business leaders want to buffer their image after the recession and the financial crisis, while Mr. Obama would gain valuable leverage if he could persuade even a few chief executives to come out in favor of higher taxes on people with incomes over $250,000.

Lloyd C. Blankfein, chief executive of Goldman Sachs, publicly endorsed higher tax rates in an opinion article published in The Wall Street Journal on Wednesday.

“I believe that tax increases, especially for the wealthiest, are appropriate, but only if they are joined by serious cuts in discretionary spending and entitlements,” he wrote.

While Mr. Blankfein and other Wall Street leaders have been speaking out about the dangers of the fiscal impasse, only one executive from the financial services industry, Kenneth I. Chenault of American Express, was at Wednesday’s meeting.

Afterward, the corporate leaders seemed pleased with the tone of the meeting but cautious about the prospect of finding common ground with the White House on the budget choices facing Congress and the president.

“I’d say everybody came away feeling pretty good about the whole discussion,” Mr. Cote said. “Now, all of us are C.E.O.’s, so we’ve learned not to confuse words with results. And that’s what we still need to see.”

Ursula M. Burns, chief executive of Xerox, who was also at the meeting, said afterward that it was clear that “we’re going to have to work through some sticking points.” But while “we didn’t get into too many specifics,” she said, it was also made clear that “we cannot go over the fiscal cliff.”

Ms. Burns’s comments about the potentially dire consequences of the fiscal impasse echoed those of other chief executives, including many in the Business Roundtable, which began an ad campaign Tuesday calling on lawmakers to resolve the issue quickly. The Campaign to Fix the Debt, a new group with a $40 million budget and the support of many Fortune 500 chiefs, began its own ad campaign on Monday.

Michael T. Duke, chief executive of Wal-Mart Stores, warned in a statement after the meeting that “before the end of the year, Washington needs to find an agreement to avoid the fiscal cliff.” He said Walmart customers “are working hard to adapt to the ‘new normal,’ but their confidence is still very fragile. They are shopping for Christmas now, and they don’t need uncertainty over a tax increase.”

Alzheimer’s Tied to Mutation Harming Immune Response

Alzheimer’s researchers and drug companies have for years concentrated on one hallmark of Alzheimer’s disease: the production of toxic shards of a protein that accumulate in plaques on the brain.

But now, in a surprising coincidence, two groups of researchers working from entirely different starting points have converged on a mutated gene involved in another aspect of Alzheimer’s disease: the immune system’s role in protecting against the disease. The mutation is suspected of interfering with the brain’s ability to prevent the buildup of plaque.

The discovery, researchers say, provides clues to how and why the disease progresses. The gene, known as TREM2, is only the second found to increase Alzheimer’s risk substantially in older people.

“It points very specifically to a potential metabolic pathway that you could intervene in to change the course of Alzheimer’s disease,” said William Thies, chief medical and scientific officer of the Alzheimer’s Association.

Much work remains to be done before scientists understand precisely how the newly discovered gene mutation leads to Alzheimer’s, but already there are some indications from studies in mice. When the gene is not mutated, white blood cells in the brain spring into action, gobbling up and eliminating the plaque-forming toxic protein, beta amyloid. As a result, Alzheimer’s can be staved off or averted.

But when the gene is mutated, the brain’s white blood cells are hobbled, making them less effective in their attack on beta amyloid.

People with the mutated gene have a threefold to fivefold increase in the likelihood of developing Alzheimer’s disease in old age.

The intact gene, says John Hardy of University College London, “is a safety net.” And those with the mutation, he adds, “are living life without a safety net.” Dr. Hardy is lead author of one of the papers.

The discovery also suggests that a new type of drug could be developed to enhance the gene’s activity, perhaps allowing the brain’s white blood cells to do their work.

“The field is in desperate need of new therapeutic agents,” said Alison Goate, an Alzheimer’s researcher at Washington University in St. Louis who contributed data to Dr. Hardy’s study. “This will give us an alternative approach.”

The fact that two research groups converged on the same gene gives experts confidence in the findings. Both studies were published online Wednesday in The New England Journal of Medicine. “Together they make a good case that this really is an Alzheimer’s gene,” said Gerard Schellenberg, an Alzheimer’s researcher at the University of Pennsylvania who was not involved with the work.

The other gene found to raise the odds that a person will get Alzheimer’s, ApoE4, is much more common and confers about the same risk as the mutated version of TREM2. But it is still not clear why ApoE4, discovered in 1993, makes Alzheimer’s more likely.

Because the mutations in the newly discovered gene are rare, occurring in no more than 2 percent of Alzheimer’s patients, it makes no sense to start screening people for them, Dr. Thies said. Instead, the discovery provides new clues to the workings of Alzheimer’s disease.

To find the gene, a research group led by Dr. Kari Stefansson of deCODE Genetics of Iceland started with a simple question.

“We asked, ‘Can we find anything in the genome that separates those who are admitted to nursing homes before the age of 75 and those who are still living at home at 85?’ ” he said.

Scientists searched the genomes of 2,261 Icelanders and zeroed in on TREM2. Mutations in that gene were more common among people with Alzheimer’s, as well as those who did not have an Alzheimer’s diagnosis but who had memory problems and might be on their way to developing Alzheimer’s.

The researchers confirmed their results by looking for the gene in people with and without Alzheimer’s in populations studied at Emory University, as well as in Norway, the Netherlands and Germany.

The TREM2 connection surprised Dr. Stefansson. Although researchers have long noticed that the brain is inflamed in Alzheimer’s patients, he had dismissed inflammation as a major factor in the disease.

“I was of the opinion that the immune system would play a fairly small role, if any, in Alzheimer’s disease,” Dr. Stefansson said. “This discovery cured me of that bias.”

Meanwhile, Dr. Hardy and Rita Guerreiro at University College London, along with Andrew Singleton at the National Institute on Aging, were intrigued by a strange, rare disease. Only a few patients had been identified, but their symptoms were striking. They had crumbling bones and an unusual dementia, sclerosing leukoencephalopathy.

“It’s a weird disease,” Dr. Hardy said.

He saw one patient in her 30s whose brain disease manifested in sexually inappropriate behavior. Also, her bones kept breaking. The disease was caused by mutations that disabled both the copy of TREM2 that she had inherited from her mother and the one from her father.

Eventually the researchers searched for people who had a mutation in just one copy of TREM2. To their surprise, it turned out that these people were likely to have Alzheimer’s disease.

They then asked researchers around the world who had genetic data from people with and without Alzheimer’s to look for TREM2 mutations.

“Sure enough, they had good evidence,” Dr. Hardy said. The mutations occurred in one-half of 1 percent of the general population but in 1 to 2 percent of patients with Alzheimer’s disease.

“That is a big effect,” Dr. Hardy said.
