Science Topics Find an Audience in Social Media

The largest and most sophisticated rover landed safely on Mars and the world’s most famous Moon visitor died, but the space event that most captured the public’s imagination in 2012 involved a journey to Earth.

On Oct. 14, YouTube counted 52 million streams of the Austrian daredevil Felix Baumgartner’s supersonic, record-breaking jump from a balloon 24 miles above the New Mexico desert. YouTube called it “one of the most-viewed live events ever,” and it landed at No. 10 on the video-sharing site’s year-end trending list — the first time a science-related subject made the list, a YouTube spokeswoman said. (Google listed the leap as No. 7 in its Zeitgeist 2012 of trending events.)

And it was far from the only science story to go viral. To put it in 140 characters or less, social media and science found each other in 2012.

Felix Baumgartner's supersonic freefall from 128k' - Mission Highlights

In surprising numbers, people posted, viewed and searched for science-related topics last year — sharing news from space and undersea, commenting on new discoveries and uploading photos and video in a full-out embrace of the ability to communicate with thousands of others about global subjects in real time.

The first Twitter message on Aug. 5 from @MarsCuriosity, NASA’s official rover handle — “Gale Crater I Am in You!!!” — was retweeted more than 72,000 times. Photos of the space shuttle Endeavour flying over the West Coast, on its way to its final resting place, ricocheted across the planet. And the director James Cameron’s claim to have sent the “deepest tweet” — from the Mariana Trench, about seven miles below the surface of the Pacific — was rated one of Twitter’s “moments of serendipity and just plain awesomeness” (though it was actually sent by a friend above water). Four science-related events made that list, with the Mars landing at No. 1.In an age of despair over math and science acuity, it appears that what was once considered uninteresting or unfathomable has become cool and exciting.

People now feel that “if they’re not paying attention, they’re missing out on something,” said Kevin Allocca, the trends manager for YouTube.

The rover in particular has picked up followers and likes at amazing speed and volume, though it is the fourth landing of an American space exploration vehicle on the planet.

“We went from 120,000 on Aug. 4 to over 800,000 followers on landing night,” Veronica McGregor, the media relations and social media manager at NASA’s Jet Propulsion Laboratory, said of its Twitter account. “And then we hit a million really quickly.”

Two months after the landing, the mission was averaging about 30,000 Twitter mentions a month. The Facebook page for NASA’s Mars rover Curiosity is heading toward a half-million likes, and the hashtag #Curiosity was the fifth most used on Google Plus in 2012.

The trend is, in some ways, self-fulfilling. Social media platforms are growing in popularity. There is also more online content, which is becoming more accessible, entertaining and engaging, Mr. Allocca said. Science subjects are also universal, more likely to attract global audiences. And people who are interested in science and technology tend to be especially comfortable with seeking and sharing information in digital ways.

Still, an epidemic of science geekiness seems to have broken out.

On Facebook, Mr. Baumgartner’s jump ranked higher than Mitt Romney’s announcement of Representative Paul D. Ryanof Wisconsin as his running mate, according to the Talk Meter, a tool that compares chatter on the social site with baseline conversation.

On the Google Zeitgeist 2012 list, “Stratosphere jump” follows “Presidential debate” (No. 6) but surpasses “Penn State scandal” (No. 8) and “Trayvon Martin shooting” (No. 9). “Hurricane Sandy” is No. 1.

NASA (which now has about 1.6 million likes on Facebook) has also become more sophisticated and assertive about doling out information piece by piece to sustain interest. The strategy plays into the strengths of social platforms, which allow users to dip in and out of streams of news and information at their convenience.

NASA’s “Seven Minutes of Terror” video on YouTube, about the difficulties of landing the rover, attracted two million views. And a satirical video made independently of NASA, “We’re NASA and We Know It” — to the tune of “I’m Sexy and I Know It” (chorus: “Crane lower that rover”) — has gotten close to 2.7 million views.

Challenges of Getting to Mars: Curiosity's Seven Minutes of Terror

There are also more ways for followers to engage in events: helping to name the rover, or picking up a Curiosity Explorer badge on Foursquare for checking in at a NASA visitor center, science museum or planetarium. Ms. McGregor said that NASA, in turn, was paying attention to what its fans want. It was learning that with so many followers just starting to connect with the whole space thing, the agency needs to provide more basic information.

Earthlings have long had a fascination with the unknown. But social media experts say people can now feel as if they are part of the adventure. They can watch events live, then incorporate the developments in their “timelines.” They can follow science — and not have to worry about taking the final exam.

Well: Managing Diabetes, Then Told of Cancer

Nine years ago, Brenda Gray, a former schoolteacher in North Carolina, discovered she had Type 2 diabetes.

Since then, she has learned to manage the disease, diligently taking her medicine and keeping tabs on her blood sugar. But in September, she was told she had skin cancer, and her diabetes spun out of control.

Ms. Gray started an aggressive course of treatment that included radiation therapy. But the treatments weakened her and destroyed her appetite. Unable to eat, she developed dangerously low blood-sugar levels, and about two months ago, Ms. Gray’s daughter had to rush her to a hospital.

“She found me in bed shaking and sweating,” said Ms. Gray, who is 62 and lives in Durham. “When I got to the hospital, they couldn’t understand how I was still standing.”

Cancer and diabetes are two of the leading killers in America. Each can be a devastating diagnosis in its own right, but researchers are finding that the two often occur together. By some estimates, as many as one in five cancer patients also has diabetes.

In a recent joint report, the American Cancer Society and the American Diabetes Association noted that people with Type 2 diabetes have an increased risk of developing cancers of the liver, pancreas, colon and bladder. Researchers with the National Cancer Institute released a similar report last year, which found greater rates of cancer among diabetics, as well as an elevated risk of dying from cancer.

Experts say it is clear from accumulating clinical data that the two share some biological links. The problem results from simple demographics as well: with the rapid rise in Type 2 diabetes and a growing population of cancer survivors, the two diseases are coinciding more frequently in older patients.

“We are going to see a lot greater numbers of people with both diseases,” said Edward Giovannucci, a professor of nutrition and epidemiology at the Harvard School of Public Health and an author of the joint report. “By some estimates, the link between diabetes and cancer may quantitatively become even more important than the link between smoking and cancer.”

Already, oncologists say, it is not uncommon to encounter patients struggling to balance cancer treatments with insulin shots and diabetes drugs. Because cancer is generally seen as the more lethal of the two diseases, patients often make it the priority.

“Although cancer is no longer generally a death sentence, for many patients, they see it as that no matter what you say,” said Dr. June McKoy, a geriatric oncologist at the Northwestern University Feinberg School of Medicine. “Suddenly, they put their diabetes on the back burner, and they focus on the cancer.” But high blood sugar can damage kidneys and blood vessels, strain the immune system and worsen cancer prognosis.

Researchers say that the link between the two diseases is complex and driven by many factors. Typically, though, it is diabetes that sets the stage for cancer. “Most cancers don’t cause diabetes,” said Dr. Pankaj Shah, an endocrinologist at the Mayo Clinic in Rochester, Minn. “Mostly diabetes increases the risk of cancer.”

Type 2 diabetes is often preceded by chronically high insulin levels and high blood sugar, fertile conditions for cancer. Insulin is known to fuel cell growth, and cancer cells consume glucose out of proportion to other nutrients. The two diseases share many risk factors as well, including obesity, poor diet, physical inactivity, smoking and advanced age.

Another factor that complicates the relationship is the treatments given to patients. Diabetes drugs can have an impact on cancer prognosis and vice versa. Type 2 diabetics treated with the drug metformin, for example, develop cancer less frequently than diabetics given other medications. A number of clinical trials are now under way to see how well the drug performs as a cancer treatment.

Drugs used against cancer, on the other hand, tend to worsen diabetes. Chemotherapy can wreak havoc on blood sugar levels, and glucocorticoids, which are widely prescribed to alleviate nausea in cancer patients, promote insulin resistance, said Dr. Lorraine L. Lipscombe of Women’s College Hospital in Toronto.

Dr. Lipscombe was the lead author of a large study last month that found that breast cancer survivors were 20 percent more likely to receive a diabetes diagnosis than other women. The study found evidence that glucocorticoids and chemotherapy may hasten the onset of diabetes.

“They don’t cause diabetes in everyone, but they can bring out or unmask it in people who might already be vulnerable,” she said.

For diabetics who are used to tightly monitoring their blood sugar levels, the impact of cancer drugs can be alarming. Rigoberto Cortes, 71, a former metal worker in Chicago, has had Type 2 diabetes for over two decades. A year ago, he was told he had Stage 3 colon cancer.

“When I started chemotherapy, my sugar level was going way up and way down like never before,” he said. “I kept asking my oncologist what I should do.”

Mr. Cortes said his oncologist was not very concerned by the blood sugar swings. He eventually got a second opinion and switched doctors. He also lost weight and changed his eating habits, which helped minimize his blood sugar swings.

Although every case is different, the general strategy in treating such patients should be to get the cancer under control first, said Dr. Shah at the Mayo Clinic.

“Diabetes treatment essentially is given to prevent long-term complications,” he added.

At some hospitals, oncologists may take responsibility for managing blood sugar and other diabetes concerns in their cancer patients. But ideally, treatments should be coordinated by a team that includes a certified diabetes educator.

“They go over diet with the patient, review their medication, review their insulin,” said Dr. McKoy of Northwestern. “They can play a big role.”

For a diabetic trying to navigate the world of cancer, or a cancer patient navigating the world of diabetes, such interventions can be crucial. In a study published in October, Dr. McKoy and her colleagues looked at several years of health records for over 200,000 people with Type II diabetes who developed cancer.

Those who underwent a diabetes counseling session after their cancer diagnosis — consisting of two sessions a week for four to six weeks — were more likely to receives tests of hemoglobin A1c levels, a barometer of how well blood sugar has been controlled over time, and to take care of their blood sugar levels. As a result, they had fewer emergency room visits, fewer hospital admissions and lower health care costs.

Ms. Gray, the former schoolteacher in Durham, learned this firsthand. After her recent emergency, she worked with a diabetes educator at Duke University Hospital. Ms. Gray learned tips and strategies to balance the two diseases, including ways to keep her blood sugar normal when cancer treatments ruin her appetite.

“I came into the hospital and they got me back on track,” she said. “I was just so focused on the cancer. It changed everything. But I’ve learned how to face this.”

A Year of Market Gains, Despite Political Turmoil

A year ago, some thought 2012 was destined to be the year that the euro zone — and maybe even the entire European Union — broke up. The banks that supported their governments, and that in turn depended on those same governments for bailouts if they went broke, were deemed to be particularly vulnerable to disaster.

It did not happen, and while the euro zone countries hardly solved their economic problems, the Continent’s stock markets turned out to be good investments in 2012, with bank shares among the best performers. The same could be said about the United States, where the broad stock market posted double-digit gains and Bank of America shares doubled in 2012, albeit from a very depressed level.

Over all, the Standard & Poor’s Euro 350-stock index was up 13 percent for the year, measured in euros, and more than 15 percent measured in dollars. The S.& P. 500 wound up the year with a gain of 13 percent.

It may have been typical of 2012 that it was politician and central bankers — not economic news or corporate developments — that dominated investor attention. As the year ended, the difference was that it was Washington, not Europe, where the squabbles were taking place.

For much of the year, it appeared that the European squabbles were leading nowhere, and by midsummer, markets were pessimistic about the outcome. Finally, Mario Draghi, the president of the European Central Bank, took decisive action to assure that the banks — and the governments that depended on them — would have access to funds. That did not turn around recessionary conditions in much of the euro zone, but it was enough to turn around financial markets. Prices of government bonds in many of the most troubled countries began to rise. Those who bet that Europe would solve its problems did well in the financial markets.

The accompanying charts show the performance of stocks in 10 economic sectors in both Europe and the United States, both in 2012 and since Oct. 9, 2007, the day that world stock markets peaked before what would turn out to be a world recession and credit crisis.

What stands out is how well financial stocks and consumer discretionary stocks did during 2012. The latter stocks are things purchased by consumers that are likely to do better when the economy is improving. In the United States, the two best such stocks in the S.& P. 500 were PulteGroup, a homebuilder, and Whirlpool, an appliance maker.

But while Europe did better in 2012, it remains much farther from recovering all of the losses experienced since the 2007 peak. The American index is just 9 percent lower than that, while the European index is about a third below where it was then. The only sectors that have completely made up their losses on both sides of the Atlantic are health care and consumer staples. In the United States, the consumer discretionary and information technology sectors have also done so, although the latter sector’s performance is largely because of Apple, whose shares are more than three times as high as they were in 2007.

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.”

YouTube Ban Lifted in Pakistan, for 3 Minutes

ISLAMABAD, Pakistan — A ban on YouTube, which Pakistan imposed after an anti-Islam video caused riots in much of the Muslim world, was lifted Saturday, only to be reinstated — after three minutes — when it was discovered that blasphemous material was still available on the site.

After months of criticism of the ban, the government decided to allow Pakistanis to have access to YouTube again, saying steps had been taken to ensure that offensive content would not be visible. But those efforts apparently failed, and the authorities quickly backtracked.

The ban was imposed on Sept. 17 following violent protests in response to the video, which was made in the United States and ridiculed the Prophet Muhammad. The government then ordered all telecommunications companies to block Internet material deemed offensive to Muslims and urged people to report such material.

But the ban on YouTube came to be seen as censorship, and a growing number of the estimated 25 million Internet users in the country complained.

“This is purely a naked power play by the government and one that we should resist,” an editorial in The Express Tribune, an English-language daily newspaper in Karachi, Pakistan, said Friday. “This is about controlling our behavior and denying us access to the Internet.”

“We need to make it clear that we do not wish to regress to a dark age when a centralized authority controlled all access to information,” the editorial, observing the 100th day of the ban, went on to say. “Retreating to such an era would essentially mean that we were longer living in a democracy.”

By Friday evening, Rehman Malik, the country’s interior minister, indicated that the ban would be lifted over the weekend. Mr. Malik said firewalls by government technicians were being installed to block pornographic and blasphemous material.

On Saturday, the Pakistan Telecommunication Authority directed local Internet service providers to make YouTube accessible. But by the afternoon, Geo, a private television news network that wields immense influence, reported that anti-Islam and blasphemous material was still available on YouTube. The criticism was led by Ansar Abbasi, a right-leaning journalist who often speaks out on morality and religion.

Yielding to the criticism, Prime Minister Raja Pervez Ashraf then ordered providers to again block access to the video-sharing site.

The flip-flop drew an immediate rebuke from users and led to a flurry of jokes on Twitter about the government’s dithering and backtracking.

“YouTube is a huge convenience for users, who benefit from it for educational as well as entertainment purposes,” Zubair Kasuri, the editor of Flare, a Karachi-based telecommunications magazine, said in a telephone interview. Mr. Kasuri expressed surprise over the government’s failure to install an effective firewall mechanism despite having months to do so.

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.

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.

Victim of Gang Rape in India Dies at Hospital in Singapore

NEW DELHI — A young woman who had been in critical condition since she was raped two weeks ago by several men who lured her onto a bus here died early Saturday, an official at the hospital in Singapore that is caring for her said.

The woman, a 23-year-old physiotherapy student whose rape on Dec. 16 had served as a reminder of the dangerous conditions women face in India, “died peacefully” early Saturday, according to a statement attributed to Mount Elizabeth Hospital in Singapore by The Associated Press.

The woman, whose intestines were removed because of injuries caused by a metal rod used during the rape, has not been identified. She was flown to Singapore on Wednesday night after being treated at a local hospital.

Revulsion and anger over the attack have galvanized India, where women regularly face sexual harassment and assault, and where neither the police nor the judicial system is seen as adequately protecting them.

Angry protesters thronged central Delhi after the attack was made public and assembled in other major cities, demanding better protection from the police and better treatment over all for women. Some protesters and politicians have called for the death penalty for rapists.

Top officials now say that change is needed.

“The emergence of women in public spaces, which is an absolutely essential part of social emancipation, is accompanied by growing threats to their safety and security,” Prime Minister Manmohan Singh said in a speech on Thursday. “We must reflect on this problem, which occurs in all states and regions of our country, and which requires greater attention.”

Activists and lawyers in India have long said that the police are insensitive when dealing with crimes against women. The result, they say, is that many women do not report cases of sexual violence. India, which has more than 1.3 billion people, recorded 24,000 cases of rape last year, a figure that has increased by 25 percent in the past six years.

On Thursday, Delhi government officials said they would register the names and photographs of convicted rapists on the Delhi police Web site, the beginning of a national registry for rapists.

As the condition of the Delhi rape victim worsened on Friday, the family of an 18-year-old woman in the northern Indian state of Punjab who committed suicide on Wednesday after being raped last month by two men blamed the police for her death.

Relatives of the woman say she killed herself because the police delayed registering the case or arresting the rapists.

If the police “had done their job, she would be alive today,” the woman’s sister, Charanjit Kaur, 28, said in a phone interview. “They didn’t listen to us; they didn’t act.”

On Friday, the Punjab high court intervened, asking the police to explain their delay. Three police officers have been suspended in the case, according to news media reports. Punjab police officials did not respond to phone calls seeking comment.

Ms. Kaur said her sister was abducted by two men from a place of worship near the small town of Badshahpur on Nov. 13 and was drugged and raped repeatedly. When the woman reported the episode at the local police station a few days later, she was asked to describe it in graphic detail and was “humiliated,” her sister said.

Over the next few days, Ms. Kaur said, her mother and sister were repeatedly called to the police station and forced to sit there all day. But the case was not registered for two weeks, as police officials and village elders tried to broker a deal between the men accused of the rape and the victim. In some parts of India, women are commonly married to men who have raped them.

Ms. Kaur said the police told her family that, because they were poor, they would not be able to fight the matter in court. “They kept putting pressure on my family to take money or marry the accused or just somehow settle the matter,” she said.

After no agreement was reached, the police registered the case, but they did not make any arrests. The victim was stalked and harassed by the men accused of the rape, who threatened to kill her and her family if she refused to drop the complaint, her suicide note said.

“They have ruined my life,” the note read, according to Ms. Kaur. The note names two men and a woman who allegedly helped the other two men as they kidnapped her. Those two men have now been arrested, the police said Friday.

Fear of Amazon Pushes Stores to Offer Same-Day Shipping

Richard Perry/The New York Times

Arianna Simpson of Shoptiques.com, a retail Web site, made a same-day delivery to a Manhattan office building last week.

Ivy Wu did not immediately need the navy lace cocktail dress she ordered the other day. But when a representative from Shoptiques, an e-commerce site, arrived at her Midtown Manhattan office with the dress only hours after Ms. Wu, 26, had placed her order, “I was really impressed that it was here,” she said.

This holiday season, same-day shipping has replaced free shipping as the new must-have promotion. It’s logistically complicated and money-losing — and may not even be a service that consumers want or need, analysts say. But retailers from Walmart to small shops like Shoptiques are willing to take the risk. Even the Postal Service has introduced a same-day option for retailers. And the reason is simple: fear of Amazon.com.

Amazon, the world’s biggest online retailer, has hinted that it will expand its same-day shipping service, giving customers the immediate gratification that has been the biggest advantage of brick-and-mortar stores.

For small outfits like Shoptiques, it is not an easy proposition. The courier who showed up at Ms. Wu’s office was the company’s head of boutique operations, who has put aside her regular job this holiday season to make deliveries by hand. Bigger retailers, like Toys “R” Us, Macy’s and Target, have worked with eBay to deliver items the same day, as have other old-line stores. Google has begun testing a local delivery service with several chains.

“There’s lots going on in this space, and it’s all driven by Amazon,” said Tom Allason, founder and chief executive of Shutl, a British same-day delivery service that will expand to the United States next year. “It’s not really being driven by consumers at the moment.”

The same-day delivery idea was a spectacular failure during the dot.com boom. Companies like Kozmo.com and Webvan went under because the services simply cost too much to be profitable. Amazon has offered same-day shipping since 2009, but with limits — only in big cities near Amazon warehouses on certain items ordered in the morning.

The geographical limits exist because Amazon had built warehouses far from major cities to avoid charging sales tax in certain states. But it has now given in on the sales tax fight, and in return, is erecting warehouses near cities like San Francisco, which analysts say is paving the way for faster, more widespread same-day delivery and spurring competitors.

“It’s the old idiom, ‘time is money,’ ” said Lina Shustarovich, an eBay spokeswoman. “How much time are you saving by not going to the store? People want it now, they want it fast.”

Walmart, which is the nation’s biggest retailer but sells just a fraction of what Amazon does online, is testing same-day shipping during the holiday season in five markets. Generally, it gives shoppers a four-hour delivery window and charges $10 for same- or next-day delivery. The idea is “to give customers convenience, by way of combining our online shopping with the local presence of stores,” said Amy Lester, a Walmart spokeswoman for global commerce.

But, Ms. Lester said, the test is showing that consumers often pick next-day delivery rather than same day. She declined to give a specific figure for same-day orders, but said thousands of same- and next-day orders had been placed.

Net-a-Porter, the designer apparel e-commerce site, said its same-day service is quite popular. Its $25 delivery service in the London and New York areas pays for itself, said Alison Loehnis, its managing director. But its clients are accustomed to paying for concierge service, like the customer who ordered clothing to be delivered the same day to her private jet before a vacation.

With the eBay Now iPhone app, introduced this year in San Francisco and New York, customers choose items from physical stores and eBay sends a courier to the store to pick it up and drop it off — at an apartment, office, coffee shop or bar — for a $5 fee.

EBay declined to say whether it loses money on the orders, but analysts who study logistics say it is not profitable.

“The goal with this pilot was never to monetize,” Ms. Shustarovich said. But in the future, it could make money, she said, for example if retailers pay eBay a fee for bringing them customers.

The Postal Service is testing a same-day service in San Francisco that is meant to offset its declining carrier business, a spokesman said. Consumers can order items until 2 p.m. from 1-800-Flowers.com, the first retailer offering the service, and a Postal Service employee will pick up the package and deliver it between 4 and 8 p.m.

Smaller companies are trying different approaches.

TaskRabbit, which offers à la carte personal assistant services, noticed last summer that delivering items from local stores was the most popular task requested.

Now, it charges $10 for delivery from local stores, starting in San Francisco.
