TimesCast Media+Tech: The right to unlock cellphones expires. | Chris Hughes, publisher of The New Republic, discusses its redesign. | An animated look at how technology may change our daily routines.
Last Updated, 2:47 p.m. This post has been updated throughout the day with reports from bloggers and journalists in Egypt, where protests and clashes continued in major cities despite an attempt to impose emergency rule.
As my colleague David Kirkpatrick reports from Egypt, there were protests in the Suez Canal city of Port Said and fresh clashes in Cairo on Monday.
Video uploaded to YouTube on Sunday showed officers firing at protesters in Port Said, killing four, including a man in a wheelchair, according to Mosireen, a collective of activist Egyptian filmmakers.
As clashes continued in Port Said on Monday, despite a declaration of martial law, journalists and bloggers there uploaded video of angry chants against the government at funerals for protesters and reports of escalating mayhem.

In Cairo, police fired tear gas on Sunday and Monday at protesters at the foot of the Kasr el-Nile bridge near Tahrir Square, which was the scene of an epic battle during the uprising against former President Hosni Mubarak exactly two years ago, on what was known as the revolution’s “Day of Rage.”

The activist blogger Omar Kamel shared dramatic photographs and video of the clashes by the bridge on Sunday, showing clouds of tear gas in front of the luxury hotels along the Nile Corniche illuminated by the protesters’ fireworks and lasers.
The Egyptian newspaper El Watan uploaded video of clashes in the same area on Monday.
The Cairene blogger who writes as Kikhote uploaded video shot from above Tahrir Square on Monday that zoomed in to the foot of the Kasr el-Nil bridge, showing the location of the bridge and what looked like hundreds of protesters gathered there.
Kikhote also drew attention to the activist blogger Rasha Azab’s photograph of a cloud of tear gas in the air above the heads of protesters near the foot of the bridge on Monday, in front of the distinctive salmon-colored facade of the Cairo Semiramis hotel.

As the 9 p.m. curfew imposed on Port Said approached, Rawya Rageh, a correspondent for Al Jazeera English, reported from the city that thousands of protesters had taken to the streets to defy the order — including the local soccer club’s most hardcore fans, the ultras, who were blamed for a deadly riot last year.

ANY list of the leading novelists of the 19th century, writing in English, would almost surely include Charles Dickens, Thomas Hardy, Herman Melville, Nathaniel Hawthorne and Mark Twain.
But they do not appear at the top of a list of the most influential writers of their time. Instead, a recent study has found, Jane Austen, author of “Pride and Prejudice, “ and Sir Walter Scott, the creator of “Ivanhoe,” had the greatest effect on other authors, in terms of writing style and themes.
These two were “the literary equivalent of Homo erectus, or, if you prefer, Adam and Eve,” Matthew L. Jockers wrote in research published last year. He based his conclusion on an analysis of 3,592 works published from 1780 to 1900. It was a lot of digging, and a computer did it.
The study, which involved statistical parsing and aggregation of thousands of novels, made other striking observations. For example, Austen’s works cluster tightly together in style and theme, while those of George Eliot (a k a Mary Ann Evans) range more broadly, and more closely resemble the patterns of male writers. Using similar criteria, Harriet Beecher Stowe was 20 years ahead of her time, said Mr. Jockers, whose research will soon be published in a book, “Macroanalysis: Digital Methods and Literary History” (University of Illinois Press).
These findings are hardly the last word. At this stage, this kind of digital analysis is mostly an intriguing sign that Big Data technology is steadily pushing beyond the Internet industry and scientific research into seemingly foreign fields like the social sciences and the humanities. The new tools of discovery provide a fresh look at culture, much as the microscope gave us a closer look at the subtleties of life and the telescope opened the way to faraway galaxies.
“Traditionally, literary history was done by studying a relative handful of texts,” says Mr. Jockers, an assistant professor of English and a researcher at the Center for Digital Research in the Humanities at the University of Nebraska. “What this technology does is let you see the big picture — the context in which a writer worked — on a scale we’ve never seen before.”
Mr. Jockers, 46, personifies the digital advance in the humanities. He received a Ph.D. in English literature from Southern Illinois University, but was also fascinated by computing and became a self-taught programmer. Before he moved to the University of Nebraska last year, he spent more than a decade at Stanford, where he was a founder of the Stanford Literary Lab, which is dedicated to the digital exploration of books.
Today, Mr. Jockers describes the tools of his trade in terms familiar to an Internet software engineer — algorithms that use machine learning and network analysis techniques. His mathematical models are tailored to identify word patterns and thematic elements in written text. The number and strength of links among novels determine influence, much the way Google ranks Web sites.
It is this ability to collect, measure and analyze data for meaningful insights that is the promise of Big Data technology. In the humanities and social sciences, the flood of new data comes from many sources including books scanned into digital form, Web sites, blog posts and social network communications.
Data-centric specialties are growing fast, giving rise to a new vocabulary. In political science, this quantitative analysis is called political methodology. In history, there is cliometrics, which applies econometrics to history. In literature, stylometry is the study of an author’s writing style, and these days it leans heavily on computing and statistical analysis. Culturomics is the umbrella term used to describe rigorous quantitative inquiries in the social sciences and humanities.
“Some call it computer science and some call it statistics, but the essence is that these algorithmic methods are increasingly part of every discipline now,” says Gary King, director of the Institute for Quantitative Social Science at Harvard.
Cultural data analysts often adapt biological analogies to describe their work. Mr. Jockers, for example, called his research presentation “Computing and Visualizing the 19th-Century Literary Genome.”
Such biological metaphors seem apt, because much of the research is a quantitative examination of words. Just as genes are the fundamental building blocks of biology, words are the raw material of ideas.
“What is critical and distinctive to human evolution is ideas, and how they evolve,” says Jean-Baptiste Michel, a postdoctoral fellow at Harvard.
Mr. Michel and another researcher, Erez Lieberman Aiden, led a project to mine the virtual book depository known as Google Books and to track the use of words over time, compare related words and even graph them.
Google cooperated and built the software for making graphs open to the public. The initial version of Google’s cultural exploration site began at the end of 2010, based on more than five million books, dating from 1500. By now, Google has scanned 20 million books, and the site is used 50 times a minute. For example, type in “women” in comparison to “men,” and you see that for centuries the number of references to men dwarfed those for women. The crossover came in 1985, with women ahead ever since.
In work published in Science magazine in 2011, Mr. Michel and the research team tapped the Google Books data to find how quickly the past fades from books. For instance, references to “1880,” which peaked in that year, fell to half by 1912, a lag of 32 years. By contrast, “1973” declined to half its peak by 1983, only 10 years later. “We are forgetting our past faster with each passing year,” the authors wrote.
JON KLEINBERG, a computer scientist at Cornell, and a group of researchers approached collective memory from a very different perspective.
This article has been revised to reflect the following correction:
Correction: January 27, 2013
An earlier version of this article misstated Matthew L. Jockers’s age. He is 46, not 48.
For decades scientists have known that the ability to remember newly learned information declines with age, but it was not clear why. A new study may provide part of the answer.
The report, posted online on Sunday by the journal Nature Neuroscience, suggests that structural brain changes occurring naturally over time interfere with sleep quality, which in turn blunts the ability to store memories for the long term.
Previous research had found that the prefrontal cortex, the brain region behind the forehead, tends to lose volume with age, and that part of this region helps sustain quality sleep, which is critical to consolidating new memories. But the new experiment, led by scientists at the University of California, Berkeley, is the first to link structural changes directly with sleep-related memory problems.
The findings suggest that one way to slow memory decline in aging adults is to improve sleep, specifically the so-called slow-wave phase, which constitutes about a quarter of a normal night’s slumber.
Doctors cannot reverse structural changes that occur with age any more than they can turn back time. But at least two groups are experimenting with electrical stimulation as a way to improve deep sleep in older people. By placing electrodes on the scalp, scientists can run a low current across the prefrontal area, essentially mimicking the shape of clean, high-quality slow waves.
The result: improved memory, at least in some studies. “There are also a number of other ways you can improve sleep, including exercise,” said Ken Paller, a professor of psychology and director of the cognitive neuroscience program at Northwestern, who was not involved in the research.
Dr. Paller said that a whole array of changes occurred across the brain during aging and that sleep was only one factor affecting memory function.
But Dr. Paller said that the study told “a convincing story, I think: that atrophy is related to slow-wave sleep, which we know is related to memory performance. So it’s a contributing factor.”
In the study, a research team in California took brain images from 19 people of retirement age and 18 in their early 20s. It found that a brain area called the medial prefrontal cortex, roughly behind the middle of the forehead, was about a third smaller on average in the older group than in the younger one — a difference due to natural atrophy over time, previous research suggests.
Before bedtime, the team had the two groups study a long list of words paired with nonsense syllables, like “action-siblis” and “arm-reconver.” The team used such nonwords because one type of memory that declines with age is for new, previously unseen information.
After training on the pairs for half an hour or so, the participants took a test on some of them. The young group outscored the older group by about 25 percent.
Then everyone went to bed — and bigger differences emerged. For one, the older group got only about a quarter of the amount of high-quality slow-wave sleep that the younger group did, as measured by the shape and consistency of electrical waves on an electroencephalogram machine, or EEG. It is thought that the brain moves memories from temporary to longer-term storage during this deep sleep.
On a second test, given in the morning, the younger group outscored the older group by about 55 percent. The estimated amount of atrophy in each person roughly predicted the difference between his or her morning and evening scores, the study found. Even seniors who were very sharp at night showed declines after sleeping.
“The analysis showed that the differences were due not to changes in capacity for memories, but to differences in sleep quality,” said Bryce A. Mander, a postdoctoral fellow at Berkeley, and the lead author of the study. His co-authors included researchers from the California Pacific Medical Center in San Francisco; the University of California, San Diego; and the Lawrence Berkeley National Laboratory.
The findings do not imply that medial prefrontal atrophy is the only age-related change causing memory problems, said Matthew P. Walker, a professor of psychology and neuroscience at Berkeley, and a co-author of the study.
“But these things are interrelated,” Dr. Walker said. “Essentially, with time, the less and less tissue you have in this prefrontal area, the less and less quality deep wave sleep you get, the less and less you remember of content that you just learned.”

Correction: January 27, 2013
An earlier version of this article misstated Matthew L. Jockers’s age. He is 46, not 48.
An intense fire ripped through a nightclub crowded with university students in southern Brazil early on Sunday morning, leaving behind a scene of horror, with bodies piled in the club’s bathrooms and on the street.
At least 232 people were killed, many of them students in the agronomy and veterinary medicine programs at a local university, police officials said.
As Simon Romero reports, a flare from a band’s pyrotechnic show ignited the fire in the nightclub, called Kiss, in the southern city of Santa Maria. Rescue workers continued to haul bodies from the still-smoldering building on Sunday.
Amateur videos posted to YouTube showed scenes of chaos as medics scurried over the bodies of victims who appeared to be unconscious, checking for signs of life.
Officials and witnesses say that security guards at the club had locked some exits, sewing panic as people attempted to flee the flames and smoke.
“Only after a multitude pushed down the security guards did they see the crap they had done,” Murilo de Toledo Tiecher, 26, a medical student who survived the fire, said in comments posted on Facebook.
Shortly before the fire, a club D.J. posted a photo on Facebook from inside the crowded club with the caption “Kiss is pumping.”
A short time later, another photo that was said to be taken outside the club and widely disseminated through social media showed smoke billowing from the front entrance.

The fire quickly engulfed the building.
Firefighters and volunteers who used T-shirts to protect themselves from the smoke struggled to pull people from the burning building.
Photos from the scene showed frantic friends and family members gathered outside the club and a hospital.
As Mr. Romero reports, witnesses said the fire started about 2 a.m. after the band, Gurizada Fangangueira, took the stage. At least one member of the five-person band, which is based in Santa Maria and advertised its use of pyrotechnics, was said to have been killed in the fire.
Overcrowding and a disregard for fire safety codes have led to deadly blazes at nightclubs in the past, though Sunday’s tragedy in Brazil is among the worst.
In 2003 in Rhode Island, a also fire set off by a pyrotechnic display at a club killed about 100 people. A fire that erupted under similar circumstances in Russia left almost as many dead in 2009.
And in Luoyang, China in 2000, 309 people were killed in a fire that broke out at a dance hall, forcing some to leap from high-rise windows.
PepsiCo announced on Friday that it would no longer use an ingredient in Gatorade after consumers complained.
The ingredient, brominated vegetable oil, which was used in citrus versions of the sports drink to prevent the flavorings from separating, was the object of a petition started on Change.org by Sarah Kavanagh, a 15-year-old from Hattiesburg, Miss., who became concerned about the ingredient after reading about it online. Studies have suggested there are possible side effects, including neurological disorders and altered thyroid hormones.
The petition attracted more than 200,000 signatures, and this week, Ms. Kavanagh was in New York City to tape a segment for “The Dr. Oz Show.” She visited The New York Times on Wednesday and while there said, “I just don’t understand why they can’t use something else instead of B.V.O.”
“I was in algebra class and one of my friends kicked me and said, ‘Have you seen this on Twitter?’ ” Ms. Kavanagh said in a phone interview on Friday evening. “I asked the teacher if I could slip out to the bathroom, and I called my mom and said, ‘Mom, we won.’ ”
Molly Carter, a spokeswoman for Gatorade, said the company had been testing alternatives to the chemical for roughly a year “due to customer feedback.” She said Gatorade initially was not going to make an announcement, “since we don’t find a health and safety risk with B.V.O.”
Because of the petition, though, Ms. Carter said the company had changed its mind, and an unidentified executive there gave Beverage Digest, a trade publication, the news for its Jan. 25 issue.
Previously, a spokesman for PepsiCo had said in an e-mail, “We appreciate Sarah as a fan of Gatorade, and her concern has been heard.”
Brominated vegetable oil will be replaced by sucrose acetate isobutyrate, an emulsifier that is “generally recognized as safe” as a food additive by the Food and Drug Administration. The new ingredient will be added to orange, citrus cooler and lemonade Gatorade, as well Gatorade X-Factor orange, Gatorade Xtremo citrus cooler and a powdered form of the drink called “glacier freeze.”
Ms. Carter said consumers would start seeing the new ingredient over the next few months as existing supplies of Gatorade sell out and are replaced.
Health advocates applauded the company’s move. “Kudos to PepsiCo for doing the responsible thing on its own and not waiting for the F.D.A. to force it to,” said Michael Jacobson, executive director of the Center for Science in the Public Interest.
Mr. Jacobson has championed the removal of brominated vegetable oil from foods and beverages for the last several decades, but the F.D.A. has left it in a sort of limbo, citing budgetary constraints that it says keep it from going through the process needed to formally ban the chemical or declare it safe once and for all.
Brominated vegetable oil is banned as a food ingredient in Japan and the European Union. About 10 percent of drinks sold in the United States contain it, including Mountain Dew, which is also made by PepsiCo; some flavors of Powerade and Fresca from Coca-Cola; and Squirt and Sunkist Peach Soda, made by the Dr Pepper Snapple Group.
PepsiCo said it had no plans to remove the ingredient from Mountain Dew and Diet Mountain Dew, both of which generate more than $1 billion in annual sales.
Heather White, executive director at the Environmental Working Group, said of PepsiCo’s decision, “We can only hope that other companies will follow suit.” She added, “We need to overhaul how F.D.A. keeps up with the latest science on food additives to better protect public health.”
Ms. Kavanagh agreed. “I’ve been thinking about ways to take this to the next level, and I’m thinking about taking it to the F.D.A. and asking them why they aren’t doing something about it,” she said. “I’m not sure yet, but I think that’s where I’d like to go with this.”

Correction: January 26, 2013
An earlier version of this article misspelled the surname of the 15-year-old who started a petition on Change.org to end the use of brominated vegetable oil in Gatorade. She is Sarah Kavanagh, not Kavanaugh.

President Obama, with his health secretary, Kathleen Sebelius, offering a compromise on the contraception mandate last year.
In a flood of lawsuits, Roman Catholics, evangelicals and Mennonites are challenging a provision in the new health care law that requires employers to cover birth control in employee health plans — a high-stakes clash between religious freedom and health care access that appears headed to the Supreme Court.
In recent months, federal courts have seen dozens of lawsuits brought not only by religious institutions like Catholic dioceses but also by private employers ranging from a pizza mogul to produce transporters who say the government is forcing them to violate core tenets of their faith. Some have been turned away by judges convinced that access to contraception is a vital health need and a compelling state interest. Others have been told that their beliefs appear to outweigh any state interest and that they may hold off complying with the law until their cases have been judged. New suits are filed nearly weekly.
“This is highly likely to end up at the Supreme Court,” said Douglas Laycock, a law professor at the University of Virginia and one of the country’s top scholars on church-state conflicts. “There are so many cases, and we are already getting strong disagreements among the circuit courts.”
President Obama’s health care law, known as the Affordable Care Act, was the most fought-over piece of legislation in his first term and was the focus of a highly contentious Supreme Court decision last year that found it to be constitutional.
But a provision requiring the full coverage of contraception remains a matter of fierce controversy. The law says that companies must fully cover all “contraceptive methods and sterilization procedures” approved by the Food and Drug Administration, including “morning-after pills” and intrauterine devices whose effects some contend are akin to abortion.
As applied by the Health and Human Services Department, the law offers an exemption for “religious employers,” meaning those who meet a four-part test: that their purpose is to inculcate religious values, that they primarily employ and serve people who share their religious tenets, and that they are nonprofit groups under federal tax law.
But many institutions, including religious schools and colleges, do not meet those criteria because they employ and teach members of other religions and have a broader purpose than inculcating religious values.
“We represent a Catholic college founded by Benedictine monks,” said Kyle Duncan, general counsel of the Becket Fund for Religious Liberty, which has brought a number of the cases to court. “They don’t qualify as a house of worship and don’t turn away people in hiring or as students because they are not Catholic.”
In that case, involving Belmont Abbey College in North Carolina, a federal appeals court panel in Washington told the college last month that it could hold off on complying with the law while the federal government works on a promised exemption for religiously-affiliated institutions. The court told the government that it wanted an update by mid-February.
Defenders of the provision say employers may not be permitted to impose their views on employees, especially when something so central as health care is concerned.
“Ninety-nine percent of women use contraceptives at some time in their lives,” said Judy Waxman, a vice president of the National Women’s Law Center, which filed a brief supporting the government in one of the cases. “There is a strong and legitimate government interest because it affects the health of women and babies.”
She added, referring to the Centers for Disease Control and Prevention, “Contraception was declared by the C.D.C. to be one of the 10 greatest public health achievements of the 20th century.”
Officials at the Justice Department and the Health and Human Services Department declined to comment, saying the cases were pending.
A compromise for religious institutions may be worked out. The government hopes that by placing the burden on insurance companies rather than on the organizations, the objections will be overcome. Even more challenging cases involve private companies run by people who reject all or many forms of contraception.
The Alliance Defending Freedom — like Becket, a conservative group — has brought a case on behalf of Hercules Industries, a company in Denver that makes sheet metal products. It was granted an injunction by a judge in Colorado who said the religious values of the family owners were infringed by the law.
“Two-thirds of the cases have had injunctions against Obamacare, and most are headed to courts of appeals,” said Matt Bowman, senior legal counsel for the alliance. “It is clear that a substantial number of these cases will vindicate religious freedom over Obamacare. But it seems likely that the Supreme Court will ultimately resolve the dispute.”
The timing of these cases remains in flux. Half a dozen will probably be argued by this summer, perhaps in time for inclusion on the Supreme Court’s docket next term. So far, two- and three-judge panels on four federal appeals courts have weighed in, granting some injunctions while denying others.
One of the biggest cases involves Hobby Lobby, which started as a picture framing shop in an Oklahoma City garage with $600 and is now one of the country’s largest arts and crafts retailers, with more than 500 stores in 41 states.
David Green, the company’s founder, is an evangelical Christian who says he runs his company on biblical principles, including closing on Sunday so employees can be with their families, paying nearly double the minimum wage and providing employees with comprehensive health insurance.
Mr. Green does not object to covering contraception but considers morning-after pills to be abortion-inducing and therefore wrong.
“Our family is now being forced to choose between following the laws of the land that we love or maintaining the religious beliefs that have made our business successful and have supported our family and thousands of our employees and their families,” Mr. Green said in a statement. “We simply cannot abandon our religious beliefs to comply with this mandate.”
The United States Court of Appeals for the 10th Circuit last month turned down his family’s request for a preliminary injunction, but the company has found a legal way to delay compliance for some months.
