Ruthless Smuggling Rings Put Rhinos in the Cross Hairs

KRUGER NATIONAL PARK, South Africa — They definitely did not look like ordinary big-game hunters, the stream of slender young Thai women who showed up on the veld wearing tight blue jeans and sneakers.

But the rhinoceros carcasses kept piling up around them, and it was only after dozens of these hulking, relatively rare animals were dead and their precious horns sawed off that an extravagant scheme came to light.

The Thai women, it ends up, weren’t hunters at all. Many never even squeezed off a shot. Instead, they were prostitutes hired by a criminal syndicate based 6,000 miles away in Laos to exploit loopholes in big game hunting rules and get its hands on as many rhino horns as possible — horns that are now literally worth more than gold.

“These girls had no idea what they were doing,” said Paul O’Sullivan, a private investigator in Johannesburg who helped crack the case. “They thought they were going on safari.”

The rhino horn rush has gotten so out of control that it has exploded into a worldwide criminal enterprise, drawing in a surreal cast of characters — not just Thai prostitutes, but also Irish gangsters, Vietnamese diplomats, Chinese scientists, veterinarians, chopper pilots, antiques dealers and recently an American rodeo star looking for a quick buck who used Facebook to find some horns.

Driven by a common belief in Asia that ground-up rhino horns can cure cancer and other ills, the trade has also been embraced by criminal syndicates that normally traffic drugs and guns, but have branched into the underground animal parts business because it is seen as “low risk, high profit,” American officials say.

“Get caught smuggling a kilo of cocaine, you will receive a very significant prison sentence,” said Ed Grace, a deputy chief with the United States Fish and Wildlife Service. But with a kilogram of rhino horn, he added, “you may only get a fine.”

The typical rhino horn is about two feet long and 10 pounds, much of it formed from the same substance as fingernails. Yet it can fetch nearly $30,000 a pound, more than crack cocaine, and conservationists worry that this “ridiculous price,” as one wildlife manager put it, could drive rhinos into extinction.

Gangs are so desperate for new sources of horn that criminals have even smashed into dozens of glass museum cases all across Europe to snatch them from exhibits.

“Astonishment and rage, that’s what we felt,” said Paolo Agnelli, a manager at the Florence Museum of Natural History, after three rhino horns were stolen last year, including a very rare one from 1824.

American federal agents recently staged a cross-country undercover rhino horn sting operation, called Operation Crash, “crash” being the term for a herd of rhinos.

Among the 12 people arrested: Wade Steffen, a champion steer wrestler from Texas, who pleaded guilty in May to trafficking dozens of horns that he found through hunters, estate sales and Facebook; and two members of an Irish gang — the same gang suspected of breaking into the museums across Europe.

In an e-mail to an undercover agent, an Irish gangster bragged: “Believe me WE NEVER LOSES A HORN TO CUSTOMS, we have so many contacts and people payed off now we can bring anything we want out of nearly any country into Europe.”

Corruption is a huge element, just like in the illegal ivory trade, in which rebel groups, government armies and threadbare hunters have been wiping out tens of thousands of elephants throughout Africa, selling the tusks to sophisticated criminal networks that move them across the globe with the help of corrupt officials.

Here in South Africa, home to the majority of the world’s last surviving 28,000 rhinos or so, the country is throwing just about everything it has to stop the slaughter — thousands of rangers, the national army, a new spy plane, even drones — but it is losing.

The number of rhinos poached in South Africa has soared in the past five years, from 13 killed in 2007 to more than 630 this year. The prehistoric, battleship-gray animals are often found on their knees, bleeding to death from a gaping stump on their face.

“Ever seen a dead rhino?” said Philip Jonker, who works for a private security firm that has gone into wildlife protection. “It’s worse than going to a funeral.”

Bits Blog: GitHub Has Big Dreams for Open-Source Software, and More

Software is not merely about automating every aspect of our lives anymore. Some of its makers want to change the way we all interact, spreading their supposed egalitarian excellence.

Whether this is liberation into a new and better mode of being (and yes, the people thinking about this take it to that scale) or the folly of an industry in love with its success is one of the more intriguing questions of a world rushing to live online.

GitHub is a San Francisco company that started in 2008 as a way for open-source software writers in disparate locations to rapidly create new and better versions of their work. Work is stored, shared and discussed, based on the idea of a “pull request,” which is a suggestion to the group for some accretive element, like several lines of code, to be “pulled,” or added, to a project.

“The concept is based around change: what is the right thing to do, what is the wrong thing?” said Tom Preston-Werner, GitHub’s co-founder and chief executive. “The efficiency of large groups working together is very low in large enterprises. We want to change that.”

Mr. Preston-Werner’s own company is something of a proxy for how he sees the world. GitHub has no managers among its 140 employees, for example. “Everyone has management interests,” he said. “People can work on things that are interesting to them. Companies should exist to optimize happiness, not money. Profits follow.” He does, however, retain his own title and decides things like salaries.

In his blog Mr. Preston-Werner has written about how important it is for  companies to expose as much of their inner workings as possible. Another member of GitHub has posted a talk that stresses how companies flourish when people want to work on certain things, not because they are told to.

This style and sentiment echoes those at another company, Asana, a corporate social network aiming to improve the pace of work. Founded by Dustin Moskovitz, who was a co-founder of Facebook and for many years ran its technology, Asana bases work on a series of to-do lists that people assign one another. Inside Asana there are no formal titles, though like GitHub there are bosses at the top who make final decisions.

For all the happiness and sharing, real money is involved here. In July GitHub received $100 million from the venture capital firm Andreessen Horowitz. This early in most software companies’ lives, $20 million would be a fortune.

Companies pay to use GitHub, and it has become an exceptionally popular way for people to do all kinds of software work; in 2012 its number of users jumped to 2.8 million from 1.2 million. The number of “repositories” — containing code, its documentation, images associated with a project or other work — increased to 4.6 million from 1.7 million last year.

Many of these are open-source projects, and GitHub does not break out their revenue.

GitHub’s popularity has also made it an important way for companies to recruit engineers, because some of the best people in the business are showing their work or dissecting the work of others inside some of the public pull requests. Its founders and backers, however, want to use the GitHub model to make mobile and enterprise software applications, and possibly much more.

Mr. Preston-Werner thinks the way open source requires a high degree of trust and collaboration among relative equals (plus a few high-level managers who define the scope of a job and make final decisions) can be extended more broadly, even into government.

“For now this is about code, but we can make the burden of decision-making into an opportunity,” he said. “It would be useful if you could capture the process of decision-making, and see who suggested the decisions that created a law or a bill.”

Can this really be extended across a large, complex organization, however?

As complex as an open-source project may be, it is also based on a single, well-defined outcome, and an engineering task that is generally free of concepts like fairness and justice, about which people can debate endlessly. Even on a less lofty plane, companies like GitHub and Asana will ultimately test themselves against complex corporate processes lasting years, and involving skills in both science and the humanities. Google once prided itself on few managers and fast action, but has found that getting big can also involve lots more meetings.

Still, these fast-rising successes may be on to something more than simply universalizing the means of their own good fortune. An early guru of the Information Age, Peter Drucker, wrote often in the latter part of his career of the need for managers to define tasks, and for workers to seek fulfillment before profits.

Essay: In Pursuit of Answers One May Not Want to Know

I jogged into the Stanford Cancer Clinic with my boyfriend, the youngest people there by two decades. We stood there sweating and holding hands, a jarring sight in the sickly light.

“You are 18, right?” the receptionist asked. Behind me, a woman so gaunt that her cheekbones protruded rolled by in a wheelchair. The oncologist called me alone to the exam room, and I told her the story I had revealed to more doctors than friends: I carry the BRCA1 mutation, which gives you a 98 percent chance of developing cancer.

When my family found out that I might have inherited the mutation from my mother, we took it as a given that I would get tested. Scientists, atheists and lawyers, we are compulsively rational. Yet when I learned I carried the mutation, I felt the cruel weight of a paradox: you can never know whether you want to know until you already do.

At Stanford, I study artificial intelligence, in which math is used to resolve these sorts of dilemmas. My teachers claim that gaining information never hurts. It can be proved mathematically that a robot with more information never makes worse decisions But we are not robots. Our eyes don’t filigree the world with coordinates and probabilities, and they can be blinded by tears.

Still, we, too, display a preference for information. We dislike uncertainty so strongly that we sometimes even prefer bad news. One study of people at risk for a terminal disease found that those who learned they were going to die from it were happier a year later than those who remained uncertain about their fates. Most people have a deep intuition that a life lived cleareyed has inherent value, independent of whether the truth makes you happy. But surely this has limits.

I know there are some things I do not want to know: which other girls my boyfriend finds attractive or the day and manner of my death. The truth can hurt in two ways. It can worsen your options: you can’t live as happily with a significant other after learning of his infidelity. Or it can make you irrational: hearing about terrorists targeting airplanes may lead you to drive instead of fly, though planes remain much safer than cars.

So was I wrong to unwind my double helix?

My risks of getting cancer at 21 are too low for me to do anything differently to better my odds. The knowledge is both irrelevant and painful; it’s obsessed me and made me behave irrationally. I wake from nightmares in which I am dying from cancer. I reread the memoirs of patients with metastatic disease until I can’t see the text through my tears. In my supposedly rational pursuit of knowledge, I’ve gone a little mad.

Despite an excess of information, I pursued more, enrolling in Stanford’s cancer biology class. The professor filled his slides with dark oncological puns, lecturing with the almost robotic detachment I sometimes see in those who work closely with cancer. Maybe I, too, am becoming robotic. I can laugh at the puns, calmly press lecturers on survival rates for breast cancer, marvel at the elegant molecular mechanisms by which it eats us alive. Just as tumors eventually swell too large for their hosts to endure, will all this knowledge grow past what I can handle?

The prospect was too much for my mother, a far tougher woman than I am. When she received a diagnosis of breast cancer, she ordered the doctors to give her chemotherapy as rapidly as possible and recovered completely. But she refused to learn her chances of long-term survival or look at her medical records. I became the first in my family to read them, and when I learned her cancer had been unusually lethal, my father asked me not to tell her.

I cannot shake the thought that this mutation was given to me for a reason. I don’t believe in God. I know my chromosomes divided along a random schism, not a divine skein. But while I reject the theist’s idea of God-granted purpose, I accept the existentialist’s idea of crafting your own. The world may be only sound and fury, but we can choose to see patterns in that chaos, stories in the stars.

So I choose to believe that I have been given this mutation so that I can discover how to overcome it. Like the protagonist in “Flowers for Algernon,” I will be both scientist and patient. Even if this sense of purpose is illusory, it lets me do what I couldn’t before. Fear has sharpened me: I wake at 3 in the morning to refine biological algorithms or to read papers on ovarian cancer.

While I believe this knowledge has made me live better, I am not sure it’s made me happier. True, there was the day I dropped by Stanford’s Relay for Life, a fund-raiser for cancer research, ran farther than I ever had and walked home full of joyful purpose. There was also the night I lost it completely and sobbed for hours in my boyfriend’s arms.

In this oscillation between light and dark, one thing remains constant: I’m no longer so eager to illuminate my fate. Recently, I went to the Web site of 23andMe, a company that will read from your genome your risk of dying from a hundred diseases. I clicked through the testimonials and was unnerved by how similar our reasons were for wanting information. I looked down at my fingertips, tempted: what else in my genome waits to be found?

But then I clicked away. The Bible doesn’t tell us if Eve ate any more apples, but I have had my fill of revelations. I am 21 years old, and I want to be free to live a normal life: fate unbound by double helix, future exploding with possibility. I don’t want to know.

Some Companies Seek to Wean Employees From Their Smartphones

Resolutions to change behavior are common at this time of year, but they usually involve exercising more or smoking less. Now, some companies are adopting policies aimed at weaning employees from their electronic devices.

Matthew Ryan Williams for The New York Times

Michelle Barry and Mark Jacobsen said they gave serious thought to work-life balance when founding Centric Brand Anthropology.

Atos, an international information technology company, plans to phase out all e-mails among employees by the end of 2013 and rely instead on personal communication. And starting in the new year, employees at Daimler, the German automaker, can have incoming e-mail automatically deleted during vacations so they do not return to a flooded in-box. An automatic message tells the sender which person is temporarily dealing with the employee’s e-mail.

No one is expected to be on call at all hours of the day and night, and “switching off” and observing quiet periods after work is important, “even if you are on a business trip,” said Sabrina Schrimpf, a Daimler spokeswoman, referring to the company’s recently released report, “Balanced! — Reconciling Employees’ Work and Private Lives.”

Disconnecting can be more challenging for business travelers who frequently work across time zones and put in long hours.

And there is a ripple effect, said Leslie A. Perlow, a professor of leadership at Harvard Business School and the author of “Sleeping With Your Smartphone.” “These guys fly in the middle of the night and send e-mails back to colleagues” who wait up, ready to respond.

A study conducted last spring by the Pew Research Center’s Internet and American Life Project found that while mobile phones were valued as a way to stay productive, there were downsides to being available at all times. The nationwide survey of 2,254 adults found that 44 percent of cellphone owners had slept with their phone next to their bed and that 67 percent had experienced “phantom rings,” checking their phone even when it was not ringing or vibrating. Still, the proportion of cellphone owners who said they “could live without it” has gone up, to 37 percent from 29 percent in 2006.

Sam Chapman, chief executive of Empower Public Relations in Chicago, said he used to feel phantom vibrations and frequently read and sent e-mail on his BlackBerry in the middle of the night. He slept poorly, did not feel refreshed in the morning and considered himself addicted. “I wanted to make sure that what happened to me didn’t happen to my employees,” he said.

So Mr. Chapman adopted what he called a BlackBerry blackout policy. He and his staff of about 20 turn off their BlackBerrys from 6 p.m. to 6 a.m. on weekdays and completely on weekends for all work-related use, with rare exceptions. “When I’m well rested, I show up to work ready to go, hit it hard, and then stop and become a human being,” he said.

He maintains that regimen while traveling, and said the policy had increased company productivity.

Professor Perlow agreed that companies could improve their bottom line by encouraging employees to turn off their devices at times. “Being constantly on actually undermines productivity,” she said.

But it is not always easy. When Michelle Barry, Mark Jacobsen and a third partner created Centric Brand Anthropology, a Seattle-based company that advises clients on brand strategy, design and culture management, they gave serious thought to the issue.

“From the beginning, a huge priority for us was to have a good balance between work-life,” said Mr. Jacobsen, Centric’s vice president and creative director. “Yet we have found that very difficult to do while working with large multinational clients,” which often require international travel and constant availability.

Being a start-up compounded those challenges. “Just because you can e-mail at 2 a.m., doesn’t mean it’s a good thing,” he said.

Centric encourages employees to prepare a week before a trip, designating a colleague as backup, informing clients about their travel plans, warning that contact may be sporadic, and trying to avoid deadlines immediately after they return. Employees are also encouraged to take spouses or partners on longer assignments and to build in downtime, said Ms. Barry, the company’s president and chief executive. When traveling herself, she said, “I make a commitment to myself not to stay up all night answering e-mails” and to limit it to about 30 minutes. She jots down after-hours thoughts using pen and paper.

Experts say there is no firm data for how many companies have policies restricting the use of electronic devices outside the office. “The companies I know actively encourage workers to stay connected after hours and on weekends,” said Dennis J. Garritan, a managing partner of the private equity firm Palmer Hill Capital and an adjunct professor at Harvard Business School.

Cold-Weather Aid Trickles Into Afghan Camps

But camp leaders and Afghan government officials criticized the aid delivery as inadequate to protect residents from the weather and to prevent more deaths.

Last winter, more than 100 children died of the cold in refugee camps around Kabul, with 26 dying in the Charahi Qambar camp alone. That is the same camp where the 3-year-old died on Friday; it was the first confirmed death because of the cold this winter.

The distribution of supplies at the camp, which is home to about 900 families in western Kabul, had been scheduled before news reports about the child’s death, said Mohammad Nader Farhad, a spokesman for the United Nations refugees agency in Kabul.

On less than an hour’s notice, the agency convened a news conference with Afghan government officials at the camp to announce the distribution.

Each family was given warm children’s clothing, blankets, tarps, cooking utensils and soap. Separately, other aid groups, financed by the United Nations and other donors, will be distributing charcoal once every month through February, officials said.

United Nations officials acknowledged, however, that the fuel distributions in themselves were not enough to heat the mud and tarp huts throughout the season, and there were no plans to distribute food to the families. In most cases the men, who are largely war-displaced refugees, are unable to find day labor work in the cold weather, so they are usually unable to buy food.

“We are happy to receive this,” said Tawoos Khan, one of the camp representatives. “But we want food, and we need more fuel; we have all run out of firewood and charcoal.” He and other camp officials said large sacks of charcoal were distributed to every family more than two weeks ago, but supplies had run out.

“It’s supplementary,” said Douglas DiSalvo, a protection officer with the United Nations agency who was at the Charahi Qambar camp. “People have some level of support they can achieve for themselves.”

Mr. Farhad said: “The assistance we are providing, at least it is mitigating the harsh winter these families are experiencing right now.”

The estimated 35,000 people in 50 camps in and around Kabul are not classified as refugees from an international legal point of view, but as “internally displaced persons.” Since the United Nations agency’s mandate is to primarily help refugees — defined as those who flee across international borders — has not provided support to the Kabul camps in the past. That changed late last winter when the Afghan government asked it to do so in response to the emergency conditions that were taking so many lives.

This year, the agency is spearheading the effort to supply the camps, along with the Afghan government’s Ministry of Refugees and Repatriation, other United Nations agencies, and several aid groups, in order to prevent a recurrence of the crisis last winter.

Ministry officials, however, criticized the effort on Sunday — even though they were among the sponsors. “We have never claimed that we provided the internally displaced Afghans with sufficient food items, clothing or means of heat. We admit this. What the internally displaced people have received so far is not adequate at all,” said Islamuddin Jurat, a spokesman for the Ministry of Refugees and Repatriation.

“Before the arrival of harsh winter, we asked the international community and donor countries to help the internally displaced people, and luckily today U.N.H.C.R. provided them with some humanitarian assistance, but again we believe it’s not sufficient at all,” he added.

Both aid officials and the Afghan government have said they are wary about providing too much aid for fear that it would encourage more people to leave their homes. That fear has also been why the Afghan government has refused to allow permanent buildings to be erected in the camps, many of which are five or more years old.

“The illegal nature of these squatter settlements poses an obstacle to more lasting interventions and improvements,” said Mr. Farhad of the United Nations refugees agency. “Coordination this year has been very strong, and we expect that the multiagency effort will help us to detect and respond to particular problem areas as the winter progresses.”

Little is provided in the way of food aid. The only food aid in the Charahi Qambar camp is a hot lunch program for 750 students at a tented school run by Aschiana, an Afghan aid group.

The United Nations High Commissioner for Refugees is providing the cold-weather packages to 40,000 families, 5,000 of them in the Kabul camps, at a cost of $6 million. Other Kabul camps will receive distributions in the next two days, Mr. Farhad said.

The packages, which cost about $150 each, include two tarpaulins, three blankets, six bars of soap, a cooking utensils set, and 26 items of clothing ranging from jackets and sweaters to socks and hats, mostly for children.

Taj Mohammad, the father of the child who died, Janan, said Sunday that he believed that his son might have survived if the cold-weather kit had arrived earlier. But like many of the refugees, he was critical of its contents, which he said were hard to sell in exchange for food.

“I didn’t know a package costs $150,” he said. “It’s a lot of money. It would have been much better if they had given us the money, and we would have spent it on what we need the most.”

Well: Exercise and the Ever-Smarter Human Brain

Anyone whose resolve to exercise in 2013 is a bit shaky might want to consider an emerging scientific view of human evolution. It suggests that we are clever today in part because a million years ago, we could outrun and outwalk most other mammals over long distances. Our brains were shaped and sharpened by movement, the idea goes, and we continue to require regular physical activity in order for our brains to function optimally.

Phys Ed

Gretchen Reynolds on the science of fitness.

The role of physical endurance in shaping humankind has intrigued anthropologists and gripped the popular imagination for some time. In 2004, the evolutionary biologists Daniel E. Lieberman of Harvard and Dennis M. Bramble of the University of Utah published a seminal article in the journal Nature titled “Endurance Running and the Evolution of Homo,” in which they posited that our bipedal ancestors survived by becoming endurance athletes, able to bring down swifter prey through sheer doggedness, jogging and plodding along behind them until the animals dropped.

Endurance produced meals, which provided energy for mating, which meant that adept early joggers passed along their genes. In this way, natural selection drove early humans to become even more athletic, Dr. Lieberman and other scientists have written, their bodies developing longer legs, shorter toes, less hair and complicated inner-ear mechanisms to maintain balance and stability during upright ambulation. Movement shaped the human body.

But simultaneously, in a development that until recently many scientists viewed as unrelated, humans were becoming smarter. Their brains were increasing rapidly in size.

Today, humans have a brain that is about three times larger than would be expected, anthropologists say, given our species’ body size in comparison with that of other mammals.

To explain those outsized brains, evolutionary scientists have pointed to such occurrences as meat eating and, perhaps most determinatively, our early ancestors’ need for social interaction. Early humans had to plan and execute hunts as a group, which required complicated thinking patterns and, it’s been thought, rewarded the social and brainy with evolutionary success. According to that hypothesis, the evolution of the brain was driven by the need to think.

But now some scientists are suggesting that physical activity also played a critical role in making our brains larger.

To reach that conclusion, anthropologists began by looking at existing data about brain size and endurance capacity in a variety of mammals, including dogs, guinea pigs, foxes, mice, wolves, rats, civet cats, antelope, mongooses, goats, sheep and elands. They found a notable pattern. Species like dogs and rats that had a high innate endurance capacity, which presumably had evolved over millenniums, also had large brain volumes relative to their body size.

The researchers also looked at recent experiments in which mice and rats were systematically bred to be marathon runners. Lab animals that willingly put in the most miles on running wheels were interbred, resulting in the creation of a line of lab animals that excelled at running.

Interestingly, after multiple generations, these animals began to develop innately high levels of substances that promote tissue growth and health, including a protein called brain-derived neurotrophic factor, or BDNF. These substances are important for endurance performance. They also are known to drive brain growth.

What all of this means, says David A. Raichlen, an anthropologist at the University of Arizona and an author of a new article about the evolution of human brains appearing in the January issue of Proceedings of the Royal Society Biology, is that physical activity may have helped to make early humans smarter.

“We think that what happened” in our early hunter-gatherer ancestors, he says, is that the more athletic and active survived and, as with the lab mice, passed along physiological characteristics that improved their endurance, including elevated levels of BDNF. Eventually, these early athletes had enough BDNF coursing through their bodies that some could migrate from the muscles to the brain, where it nudged the growth of brain tissue.

Those particular early humans then applied their growing ability to think and reason toward better tracking prey, becoming the best-fed and most successful from an evolutionary standpoint. Being in motion made them smarter, and being smarter now allowed them to move more efficiently.

And out of all of this came, eventually, an ability to understand higher math and invent iPads. But that was some time later.

The broad point of this new notion is that if physical activity helped to mold the structure of our brains, then it most likely remains essential to brain health today, says John D. Polk, an associate professor of anthropology at the University of Illinois at Urbana-Champaign, and co-author, with Dr. Raichlen, of the new article.

And there is scientific support for that idea. Recent studies have shown, he says, that “regular exercise, even walking,” leads to more robust mental abilities, “beginning in childhood and continuing into old age.”

Of course, the hypothesis that jogging after prey helped to drive human brain evolution is just a hypothesis, Dr. Raichlen says, and almost unprovable.

But it is compelling, says Harvard’s Dr. Lieberman, who has worked with the authors of the new article. “I fundamentally agree that there is a deep evolutionary basis for the relationship between a healthy body and a healthy mind,” he says, a relationship that makes the term “jogging your memory” more literal than most of us might have expected and provides a powerful incentive to be active in 2013.

Bramble of the University of Utah published a seminal article in the journal Nature titled “Endurance Running and the Evolution of Homo,” in which they posited that our bipedal ancestors survived by becoming endurance athletes, able to bring down swifter prey through sheer doggedness, jogging and plodding along behind them until the animals dropped.

Endurance produced meals, which provided energy for mating, which meant that adept early joggers passed along their genes. In this way, natural selection drove early humans to become even more athletic, Dr. Lieberman and other scientists have written, their bodies developing longer legs, shorter toes, less hair and complicated inner-ear mechanisms to maintain balance and stability during upright ambulation. Movement shaped the human body.

But simultaneously, in a development that until recently many scientists viewed as unrelated, humans were becoming smarter. Their brains were increasing rapidly in size.

Today, humans have a brain that is about three times larger than would be expected, anthropologists say, given our species’ body size in comparison with that of other mammals.

To explain those outsized brains, evolutionary scientists have pointed to such occurrences as meat eating and, perhaps most determinatively, our early ancestors’ need for social interaction. Early humans had to plan and execute hunts as a group, which required complicated thinking patterns and, it’s been thought, rewarded the social and brainy with evolutionary success. According to that hypothesis, the evolution of the brain was driven by the need to think.

But now some scientists are suggesting that physical activity also played a critical role in making our brains larger.

To reach that conclusion, anthropologists began by looking at existing data about brain size and endurance capacity in a variety of mammals, including dogs, guinea pigs, foxes, mice, wolves, rats, civet cats, antelope, mongooses, goats, sheep and elands. They found a notable pattern. Species like dogs and rats that had a high innate endurance capacity, which presumably had evolved over millenniums, also had large brain volumes relative to their body size.

The researchers also looked at recent experiments in which mice and rats were systematically bred to be marathon runners. Lab animals that willingly put in the most miles on running wheels were interbred, resulting in the creation of a line of lab animals that excelled at running.

Interestingly, after multiple generations, these animals began to develop innately high levels of substances that promote tissue growth and health, including a protein called brain-derived neurotrophic factor, or BDNF. These substances are important for endurance performance. They also are known to drive brain growth.

What all of this means, says David A. Raichlen, an anthropologist at the University of Arizona and an author of a new article about the evolution of human brains appearing in the January issue of Proceedings of the Royal Society Biology, is that physical activity may have helped to make early humans smarter.

“We think that what happened” in our early hunter-gatherer ancestors, he says, is that the more athletic and active survived and, as with the lab mice, passed along physiological characteristics that improved their endurance, including elevated levels of BDNF. Eventually, these early athletes had enough BDNF coursing through their bodies that some could migrate from the muscles to the brain, where it nudged the growth of brain tissue.

Those particular early humans then applied their growing ability to think and reason toward better tracking prey, becoming the best-fed and most successful from an evolutionary standpoint. Being in motion made them smarter, and being smarter now allowed them to move more efficiently.

And out of all of this came, eventually, an ability to understand higher math and invent iPads. But that was some time later.

The broad point of this new notion is that if physical activity helped to mold the structure of our brains, then it most likely remains essential to brain health today, says John D. Polk, an associate professor of anthropology at the University of Illinois at Urbana-Champaign, and co-author, with Dr. Raichlen, of the new article.

And there is scientific support for that idea. Recent studies have shown, he says, that “regular exercise, even walking,” leads to more robust mental abilities, “beginning in childhood and continuing into old age.”

Of course, the hypothesis that jogging after prey helped to drive human brain evolution is just a hypothesis, Dr. Raichlen says, and almost unprovable.

But it is compelling, says Harvard’s Dr. Lieberman, who has worked with the authors of the new article. “I fundamentally agree that there is a deep evolutionary basis for the relationship between a healthy body and a healthy mind,” he says, a relationship that makes the term “jogging your memory” more literal than most of us might have expected and provides a powerful incentive to be active in 2013.

Negotiations Break Down on Debt Agreement

Pete Souza/The White House, via NBC

President Obama spoke with David Gregory of NBC's "Meet The Press" in the Blue Room of the White House during an interview taped on Saturday.

WASHINGTON — Negotiations to reach a last-ditch agreement to head off large tax increases and sweeping spending cuts in the new year broke down, at least temporarily, on Sunday after Republicans requested that a deal include a new way of calculating inflation that would lower payments to beneficiaries programs like Social Security and slow their growth.

A Senate Democratic aide familiar with the talks said the negotiations could resume, and Republican officials hinted that their position was not set in stone. But for now, the Democratic aide said, talks have stopped.

Senator Mitch McConnell, the Republican leader, went to the Senate floor a little after 2 p.m. to say that Republicans had made their last offer at 7:10 the night before and had yet to receive a reply.

“I’m concerned about the lack of urgency. I think we all know we’re running out of time,” Mr. McConnell said.

Senator Harry Reid, the majority leader, responded that “at this stage, we’re not able to make a counter offer.” He said that Mr. McConnell had negotiated in good faith but that “we’re apart on some pretty big issues.”

Mr. McConnell said he had made an emergency call to Vice President Joseph R. Biden Jr. to get the talks started again.

Talks foundered after Republicans dug in in an effort to get the largest deficit reduction deal in the time remaining, according to numerous Republican and Democratic officials familiar with the negotiations. Republicans told Democrats that they were willing to put off scheduled cuts in payments to health care providers who treat Medicare patients but that they wanted spending cuts elsewhere.

But it was the inflation calculation that forced Democrats from the negotiating table. President Obama has said that in a “grand bargain” on deficit reduction, he would go along with the change, which would slow the growth of programs whose outlays rise with consumer prices, and would raise more revenue by pushing people into higher tax brackets.

Democrats said that Mr. Obama and Congressional Democrats would accept that change, called “chained C.P.I.,” only as part of a larger deal that included locking in well more than $1 trillion in revenue over 10 years, along with other Republican concessions. Democrats fear that any such concessions now would only increase demands for addition concessions in the coming weeks, when talks resume on a “grand bargain” to reduce the deficit.

They point to the $1 trillion in spending cuts agreed to last year in the Budget Control Act. Democrats say those should be included in a $4 trillion “grand bargain” package, but Republicans say those cuts should not be part of future negotiations. Republicans would likely do the same if Democrats agree now to concessions on the inflation calculation, Democratic aides said Sunday.

Mr. Reid made clear that Democrats did not intend to include Social Security in any stopgap package. Doing so would make it hard for him to round up votes from his own party, and he has resisted touching Social Security.

“We’re not going to have any Social Security cuts,” Mr. Reid said on the floor.

The breakdown came after Mr. Obama appeared on the NBC program “Meet the Press” on Sunday and implored Congress to act.

“We have been talking to the Republicans ever since the election was over,” Mr. Obama said in the interview, which was taped on Saturday. “They have had trouble saying yes to a number of repeated offers. Yesterday I had another meeting with the leadership, and I suggested to them if they can’t do a comprehensive package of smart deficit reductions, let’s at minimum make sure that people’s taxes don’t go up and that two million people don’t lose their unemployment insurance.”

“And I was modestly optimistic yesterday, but we don’t yet see an agreement,” Mr. Obama said. “And now the pressure’s on Congress to produce.”

Unless Congress acts by midnight Monday, a broad set of tax increases and federal spending cuts will be automatically imposed on Jan. 1, affecting virtually every taxpayer and government program. The spending cuts were put in place earlier this year as draconian incentives that would force the president and lawmakers to confront the nation’s growing debt. Now, lawmakers are trying to keep them from happening, though it seemed likely that the cuts, known as sequestration, would be left for the next Congress, to be sworn in this week.

Both sides worry that the confrontational tone that the president took on “Meet the Press” was not helpful.

E.U. May ‘Unravel’ if U.K. Quits, Official Says

LONDON — Almost 40 years after Britain joined the forerunner of today’s European Union, the debate over the country’s future in the Union has quickened with a warning from a top E.U. official that any moves to renegotiate the terms of British membership could wreck the bloc.

Herman Van Rompuy, president of the European Council, the body that groups the 27 E.U. member states, said that the European Union had benefited tremendously from British membership and that Britain’s departure would be like seeing “a friend walk off into the desert.”

But Mr. Van Rompuy also suggested that the strategy developed by Prime Minister David Cameron to restore dwindling public support for keeping Britain inside the bloc was likely to fail.

In an interview published Friday in The Guardian, a British daily, Mr. Van Rompuy said that renegotiation could undermine the one part of the European Union that Mr. Cameron says he values most: the single market under which around 500 million Europeans can do business without barriers.

“If every member state were able to cherry-pick those parts of existing policies that they most like, and opt out of those that they least like, the Union in general, and the single market in particular, would soon unravel,” he said.

The intervention from Mr. Van Rompuy highlights the fact that other nations are likely to resent a process under which Britain seeks to retain the parts of E.U. membership that it likes, while rejecting the rest. In order to renegotiate British membership terms, all other member states would have to agree on the changes.

And, if that sort of discussion begins, other countries may make demands too, including some that could weaken the single market which seeks to establish a level playing field on trading issues.

“All member states can, and do, have particular requests and needs that are always taken into consideration as part of our deliberations,” Mr. Van Rompuy said in the interview. “I do not expect any member state to seek to undermine the fundamentals of our cooperative system in Europe.”

Mr. Cameron argues that, to persuade euro-skeptical British voters to stay in the European Union, the country should loosen its political and social policy ties to the Union and refocus them around Europe’s single economic market. He wants to renegotiate the terms of British membership and seek approval for the result of that negotiation from the public, possibly in a referendum.

Britain formally joined in the process of European integration in 1973, when it acceded to the European Economic Community. Two years later, after a change of government and negotiations on the terms of membership, it held a referendum in which around two-thirds of those who voted elected to stay.

One theory in Britain is that the euro debt crisis presents a new opportunity to re-fashion the process of European integration because the 17 countries that use the single currency may need to rewrite the Union’s governing treaties in order to become more closely integrated. That could give Britain the chance to negotiate its looser relationship simultaneously as part of a grand bargain.

Mr. Van Rompuy suggested, however, that such a rewriting of the treaties might not happen because it might not be necessary.

“The treaties allow a considerable degree of flexibility and much can be done without needing to amend them,” he told The Guardian. “It is perfectly possible to write all kinds of provisions into the treaties, but amending them is a lengthy and cumbersome procedure needing the unanimous agreement of every single member government and ratification.”

Mr. Van Rompuy’s comments come at a sensitive moment, ahead of a widely anticipated speech by Mr. Cameron, expected in mid-January, during which he might make the promise of a referendum explicit. Many of his own lawmakers now want Mr. Cameron to promise a straight “in or out” vote, though he has so far resisted.

The political mood within Mr. Cameron’s Conservative Party has hardened against engagement with Europe, partly because of the rise in popular support for the U.K. Independence Party, which has campaigned for Britain to leave the European Union and for tighter immigration controls.

UKIP is expected to do well in the next elections to the European Parliament in 2014, which will be held under a proportional electoral system that favors smaller parties. The party is unlikely to win many, or even any, seats in British parliamentary elections, expected the following year, because these will be fought under a first-past-the post system that tends to favor mainstream parties.

The smaller party could, though, take enough votes from the Conservative Party to deprive it of the seats it will need to form the next government.

Surgery Returns to NYU Langone Medical Center

Chang W. Lee/The New York Times

Senator Charles E. Schumer spoke at a news conference Thursday about the reopening of NYU Langone Medical Center.

NYU Langone Medical Center opened its doors to surgical patients on Thursday, almost two months after Hurricane Sandy overflowed the banks of the East River and forced the evacuation of hundreds of patients.

While the medical center had been treating many outpatients, it had farmed out surgery to other hospitals, which created scheduling problems that forced many patients to have their operations on nights and weekends, when staffing is traditionally low. Some patients and doctors had to postpone not just elective but also necessary operations for lack of space at other hospitals.

The medical center’s Tisch Hospital, its major hospital for inpatient services, between 30th and 34th Streets on First Avenue, had been closed since the hurricane knocked out power and forced the evacuation of more than 300 patients, some on sleds brought down darkened flights of stairs.

“I think it’s a little bit of a miracle on 34th Street that this happened so quickly,” Senator Charles E. Schumer of New York said Thursday.

Mr. Schumer credited the medical center’s leadership and esprit de corps, and also a tour of the damaged hospital on Nov. 9 by the administrator of the Federal Emergency Management Agency, W. Craig Fugate, whom he and others escorted through watery basement hallways.

“Every time I talk to Fugate there are a lot of questions, but one is, ‘How are you doing at NYU?’ ” the senator said.

The reopening of Tisch to surgery patients and associated services, like intensive care, some types of radiology and recovery room anesthesia, was part of a phased restoration that will continue. Besides providing an essential service, surgery is among the more lucrative of hospital services.

The hospital’s emergency department is expected to delay its reopening for about 11 months, in part to accommodate an expansion in capacity to 65,000 patient visits a year, from 43,000, said Dr. Andrew W. Brotman, its senior vice president and vice dean for clinical affairs and strategy.

In the meantime, NYU Langone is setting up an urgent care center with 31 bays and an observation unit, which will be able to treat some emergency patients. It will initially not accept ambulances, but might be able to later, Dr. Brotman said. Nearby Bellevue Hospital Center, which was also evacuated, opened its emergency department to noncritical injuries on Monday.

Labor and delivery, the cancer floor, epilepsy treatment and pediatrics and neurology beyond surgery are expected to open in mid-January, Langone officials said. While some radiology equipment, which was in the basement, has been restored, other equipment — including a Gamma Knife, a device using radiation to treat brain tumors — is not back.

The flooded basement is still being worked on, and electrical gear has temporarily been moved upstairs. Mr. Schumer, a Democrat, said that a $60 billion bill to pay for hurricane losses and recovery in New York and New Jersey was nearing a vote, and that he was optimistic it would pass in the Senate with bipartisan support. But the measure’s fate in the Republican-controlled House is far less certain.

The bill includes $1.2 billion for damage and lost revenue at NYU Langone, including some money from the National Institutes of Health to restore research projects. It would also cover Long Beach Medical Center in Nassau County, Bellevue, Coney Island Hospital and the Veterans Affairs hospital in Manhattan.

China Toughens Restrictions on Internet Use

HONG KONG — The Chinese government issued new rules on Friday requiring Internet users to provide their real names to service providers, while assigning Internet companies greater responsibility for deleting forbidden postings and reporting them to the authorities.

The decision came as government censors have sharply stepped up restrictions on China’s international Internet traffic in recent weeks. The restrictions are making it harder for businesses to protect commercial secrets and for individuals to view overseas Web sites that the Chinese Communist Party deems politically sensitive.

The new regulations, issued by the Standing Committee of the National People’s Congress, allow Internet users to continue to adopt pseudonyms for their online postings, but only if they first provide their real names to service providers, a measure that could chill some of the vibrant discourse on the country’s Twitter-like microblogs. The authorities periodically detain and even jail Internet users for politically sensitive comments, such as calls for a multiparty democracy or accusations of impropriety by local officials.

Any entity providing Internet access, including over fixed-line or mobile phones, “should when signing agreements with users or confirming provision of services, demand that users provide true information about their identities,” the committee ordered.

In recent weeks, Internet users in China have exposed a series of sexual and financial scandals that have led to the resignations or dismissals of at least 10 local officials. International news media have also published a series of reports in recent months on the accumulation of wealth by the family members of China’s leaders, and some Web sites carrying such reports, including Bloomberg’s and the English- and Chinese-language sites of The New York Times, have been assiduously blocked, while Internet comments about them have been swiftly deleted.

The regulations issued Friday build on a series of similar administrative guidelines and municipal rules issued over the past year. China’s mostly private Internet service providers have been slow to comply with them, fearing the reactions of their customers. The committee’s decision has much greater legal force, and puts far more pressure on Chinese Internet providers to comply more quickly and more comprehensively, Internet specialists said.

In what appeared to be an effort to make the decision more palatable to the Chinese public, the committee also included a mandate for businesses in China to be more cautious in gathering and protecting electronic data.

“Nowadays on the Internet there are very serious problems with citizens’ personal electronic information being recklessly collected, used without approval, illegally disclosed, and even traded and sold,” Li Fei, a deputy director of the committee’s legislative affairs panel, said on Friday at a news conference in Beijing. “There are also a large number of cases of invasive attacks on information systems to steal personal electronic information, as well as lawbreaking on the Internet through swindles and through defaming and slandering others.”

Mr. Li denied that the government was seeking to prevent the exposure of corruption.

“When citizens exercise these rights according to the law, no organization or individual can use any reason or excuse to interfere, and cannot suppress them or exact revenge,” he said. “At the same time, when citizens exercise their rights, including through use of the Internet, they should stay within the bounds of the Constitution and the laws, and must not harm the legitimate rights and interests of the state, society, the collective or of other citizens.”

A spokesman for the National People’s Congress said that 145 members of the committee voted in favor of the new rules, with 5 abstaining and 1 voting against them.

The requirement for real names appeared to be aimed particularly at cellphone companies and other providers of mobile Internet access. At the news conference, an official from the Ministry of Industry and Information Technology, Zhao Zhiguo, said that nearly all fixed-line services now had real-name registration, but that only about 70 percent of mobile phones were registered under real names.

Iran’s Only Female Cabinet Minister Dismissed

Iran’s president on Thursday dismissed his health minister, the only woman to serve in the cabinet since the 1979 Islamic revolution, after she publicly criticized the government’s response to acute shortages of medicine imports, an indirect consequence of the Western sanctions imposed on the country.

Accounts in the state-run news media of the dismissal of the minister, Marzieh Vahid-Dastjerdi, did not provide an explanation for it. Iran’s Press TV Web site said President Mahmoud Ahmadinejad had appointed a caretaker health minister, Mohammad Hassan Tariqat-Monfared, and had told him in a presidential decree that the reduction of people’s health care expenses was among “the main priorities of this important ministry.”

Dr. Vahid-Dastjerdi, a gynecologist, was appointed in 2009 and is considered an advocate of women’s rights in Iranian society. She spoke out last month, apparently angering the president, by saying that an allocation in the budget of foreign currency needed to purchase medicines abroad was inadequate.

“I have heard that luxury cars have been imported with subsidized dollars, but I don’t know what happened to the dollars that were supposed to be allocated for importing medicine,” Dr. Vahid-Dastjerdi said on state television, according to a translation of her remarks reported by Reuters.

Absent such an allocation, she said, it was necessary to impose a large increase in the price of medicines, which would add to the inflationary pressures already afflicting the economy because of a plunge in value this year of the Iranian currency, the rial. Mr. Ahmadinejad opposed the price increase.

Many economists have attributed the rial’s depreciation to Iran’s increased isolation, a consequence of the penalties imposed by the United States and European Union to pressure Iran to stop enriching uranium for its disputed nuclear energy program. Some of Mr. Ahmadinejad’s critics in Iran have also blamed the currency problems on what they call his economic mismanagement.

The medicine shortage in Iran has become an urgent problem because many Western-made drugs are increasingly hard to obtain. Under the sanctions, a broad Western ban on many financial transactions with Iran has dissuaded many foreign companies from doing business with the country, even though medicines are among items exempted from the sanctions.

Recently, the president of the Iranian Academy of Medical Sciences, Seyed Alireza Marandi, bitterly complained about the medical impact of the sanctions in a letter to Ban Ki-moon, the United Nations secretary general. Dr. Marandi called the sanctions brutal measures that had increased mortality rates “as a result of the unavailability of essential drugs and shortages of medical supplies and equipment,” according to a report by the Fars News Agency.

Libraries Try to Update the Bookstore Model

Tyler Bissmeyer for The New York Times

Vicki Culler shops for discounted books at The Friends of the Public Library in Cincinnati.

At the bustling public library in Arlington Heights, Ill., requests by three patrons to place any title on hold prompt a savvy computer tracking system to order an additional copy of the coveted item. That policy was intended to eliminate the frustration of long waits to check out best sellers and other popular books. But it has had some unintended consequences, too: the library’s shelves are now stocked with 36 copies of “Fifty Shades of Grey.”

Of course, librarians acknowledge that when patrons’ passion for the sexy series lacking in literary merit cools in a year or two, the majority of volumes in the “Fifty Shades” trilogy will probably be plucked from the shelves and sold at the Friends of the Library’s used-book sales, alongside other poorly circulated, donated and out-of-date materials.

“A library has limited shelf space, so you almost have to think of it as a store, and stock it with the things that people want,” said Jason Kuhl, the executive director of the Arlington Heights Memorial Library. Renovations going on there now will turn a swath of the library’s first floor into an area resembling a bookshop, where patrons will be pampered with cozy seating, a vending cafe and, above all, an abundance of best sellers.

As librarians across the nation struggle with the task of redefining their roles and responsibilities in a digital age, many public libraries are seeing an opportunity to fill the void created by the loss of traditional bookstores. Indeed, today’s libraries are increasingly adapting their collections and services based on the demands of library patrons, whom they now call customers. Today’s libraries are reinventing themselves as vibrant town squares, showcasing the latest best sellers, lending Kindles loaded with e-books, and offering grassroots technology training centers. Faced with the need to compete for shrinking municipal finances, libraries are determined to prove they can respond as quickly to the needs of the taxpayers as the police and fire department can.

“I think public libraries used to seem intimidating to many people, but today, they are becoming much more user-friendly, and are no longer these big, impersonal mausoleums,” said Jeannette Woodward, a former librarian and author of “Creating the Customer-Driven Library: Building on the Bookstore Model.”

“Public libraries tread a fine line,” Ms. Woodward said. “They want to make people happy, and get them in the habit of coming into the library for popular best sellers, even if some of it might be considered junk. But libraries also understand the need for providing good information, which often can only be found at the library.”

Cheryl Hurley, the president of the Library of America, a nonprofit publisher in New York “dedicated to preserving America’s best and most significant writing,” said the trend of libraries that cater to the public’s demand for best sellers is not surprising, especially given the ravages of the recession on public budgets.

Still, Ms. Hurley remains confident that libraries will never relinquish their responsibility to also provide patrons with the opportunity to discover literary works of merit, be it the classics, or more recent fiction from novelists like Philip Roth, whose work is both critically acclaimed and immensely popular.

“The political ramifications for libraries today can result in driving the collection more and more from what the people want, rather than libraries shaping the tastes of the readers,” Ms. Hurley said. “But one of the joys of visiting the public library is the serendipity of discovering another book, even though you were actually looking for that best seller that you thought you wanted.”

“It’s all about balancing the library’s mission and its marketing, and that is always a tricky dance,” she added.

While print books, both fiction and nonfiction, still make up the bulk of most library collections – e-books remain limited to less than 2 percent of many collections in part because some publishers limit their availability at libraries — building renovation plans these days rarely include expanding shelf space for print products. Instead, many libraries are culling their collections and adapting floor plans to accommodate technology training programs, as well as mini-conference rooms that offer private, quiet spaces frequently requested by self-employed consultants meeting with clients, as well as teenagers needing space to huddle over group projects.

Measles: Measles Epidemic Is Spreading in Central Africa

Jehad Nga for The New York Times

An internally displaced persons camp in Goma, in the Democratic Republic of Congo. In addition to recent violence in the country, a spreading measles epidemic is further endangering the lives of thousands of children there.

A large measles epidemic is spreading in Central Africa, endangering the lives of thousands of children, the medical charity Doctors Without Borders warned last week.

Since October, the charity has vaccinated more than 226,000 children in the eastern part of the Democratic Republic of Congo. The organization has also treated nearly 13,000 Congolese for the effects of the disease.

Measles is very contagious. In places where many children are malnourished and vitamin-deficient, it kills 1 percent to15 percent of those who don’t receive medical care, Doctors Without Borders estimated. (Even in the United States in the 1990s, although cases were rare, the fatality rate was 0.3 percent, according to the Centers for Disease Control and Prevention. In AIDS patients, the rate is 30 percent.)

The eastern Congo basin has serious shortages of medical workers and of drugs. While there is no treatment for measles itself, antibiotics can save those who develop pneumonia, meningitis or other secondary infections. Measles can also cause blindness by scarring the eyeball.

The outbreak is taking place despite enormous success against the disease worldwide. According to a study released earlier this year, deaths from measles have dropped by almost 75 percent since 2000.

Most of the lives saved were in Africa and India. Measles shots are often cited as one of the chief reasons that deaths of children under age 5 around the world have fallen steadily.

Senate Leader Says Deal Is Unlikely Before Fiscal Deadline

WASHINGTON — Senator Harry Reid of Nevada, the majority leader, warned Thursday that there was scant time to put together a Congressional deal to avert the impending fiscal crisis and that no resolution was in sight.

T.J. Kirkpatrick for The New York Times

Senator Harry Reid arrived at the Capitol on Thursday in Washington.

“I have to be very honest,” Mr. Reid said as the Senate convened in an unusual session between Christmas and New Year’s Day. “I don’t know time-wise how it can happen now.”

Mr. Reid offered his pessimistic assessment shortly before President Obama, cutting his vacation short, arrived back in Washington on Air Force One. White House officials said that before leaving Hawaii, Mr. Obama had spoken separately by phone with each of the four Congressional leaders about the status of negotiations, but they gave no details of the discussion.

Mr. Obama is expected to invite all four lawmakers to meet on Friday. In a related development, House Republicans were told to return to Washington on Sunday. Republican senators were planning to convene at the Capitol — normally somnolent during Christmas week — to strategize.

On the Senate floor Thursday, Mr. Reid excoriated House Republicans for failing to consider a Senate-passed measure that would extend lower tax rates on household income up to $250,000. He urged House members to return to the Capitol to put together at least a modest deal to avoid the more than half-a-trillion dollars in automatic tax increases and spending cuts set to begin in January.

“The American people are waiting for the ball to drop,” Mr. Reid said, “but it’s not going to be a good drop.”

A spokesman for Senator Mitch McConnell, Republican of Kentucky and the minority leader, confirmed that he had spoken with the president, and said that Mr. McConnell was “happy to review what the president has in mind.” But the spokesman, Don Stewart, said Senate Democrats had not come ahead with a plan.

“When they do, members on both sides of the aisle will review the legislation and make decisions on how best to proceed,” Mr. Stewart said.

Mr. Reid said that absent a move from Republicans, the Senate would move forward this week on a national security measure concerning espionage, as well as a bill to help states that have suffered hurricane damage, with multiple votes possible.

“We are here in Washington working,” Mr. Reid said, “while the members of the House of Representatives are out watching movies and watching their kids play soccer and basketball and doing all kinds of things. They should be here.”

Senators, frustrated, pessimistic and in some cases downright miserable, returned to Washington with no clear fiscal agenda. Senator Ben Nelson, a retiring Democrat of Nebraska, arrived shortly after midnight on Thursday on a flight that was delayed more than four hours. As he walked through the airport, he lamented the deteriorating political comity that he has observed during two terms in the Senate and two terms as a Democratic governor of a conservative state.

“There are folks who are elected who have come here with an agenda to do nothing and want to stop everything,” Mr. Nelson said in an interview. “It may be the new norm – blocking everything.”

For Mr. Nelson, who decided against seeking a third term, the looming fiscal crisis would be the final legislative act of a political career built around a bipartisan voting record. He said he was not confident that a real deal could be reached that would be acceptable to both sides, considering that Congress is filled with many people “who didn’t accept the 2008 presidential election and haven’t accepted the 2012 election either.”

United Arab Emirates Arrests Suspects in Terror Plots

DUBAI, United Arab Emirates (Reuters) — Security forces in the United Arab Emirates have arrested members of a cell made up of militants from Saudi Arabia and the emirates who were planning to carry out attacks in both countries and in other states, the official Emirates News Agency said on Wednesday.

The federation of seven emirates, a major oil exporter and an ally of the United States, has had no attacks by Al Qaeda or other terrorist groups. But Islamist sentiment has risen in recent years, and Dubai, a business and tourism hub that attracts many Westerners, could make an attractive target for militants, analysts say.

The suspects had acquired materials and equipment for use in what the news agency called terrorist operations.

“The security authorities in the U.A.E., in coordination with the related security parties in Saudi Arabia, announced the arrest of an organized cell from the deviant group that was planning to carry out actions against national security of both countries and some brotherly states,” the agency said, without elaborating.

The phrase “deviant group” is often used by the authorities in Saudi Arabia to describe Al Qaeda.

In August, the Saudi authorities arrested a group of militants in Riyadh — mostly Yemeni nationals — suspected of having links to Al Qaeda. Thousands of people believed to be militants have been arrested since dozens were killed in terrorist attacks between 2003 and 2006 on Saudi residential compounds and offices for foreign workers and on government facilities.

The United States has poured aid into Yemen to stem the threat of attacks from the group Al Qaeda in the Arabian Peninsula and to try to prevent any spillover of violence into Saudi Arabia, the world’s top oil exporter.

In 2010, Al Qaeda in the Arabian Peninsula, formed with the merger of Al Qaeda’s Yemeni and Saudi branches, said it was behind a plot to send two parcel bombs to the United States. The bombs were intercepted in Britain and Dubai.

Though the emirates have escaped much of the upheaval that has shaken the Arab world, the authorities have moved swiftly to stem any sign of political dissent, detaining more than 60 Islamists this year over suspected threats to state security and links to foreign groups.

Those detainees, who belong to an Islamist group called Al-Islah, have confessed to setting up a secret organization with an armed force whose aim was to take power and establish an Islamic state, the local news media reported in September. The group denied the accusations.

Many of the detained Islamists are from the more religiously conservative northern emirates like Sharjah and Ras al-Khaimah, which produced one of the Sept. 11 hijackers.
