THE only time art ever seems to make news here in the West anymore is when a Pollock or Warhol sells for a sum commensurate with the budget of a “Transformers” film. It seems bizarre, then, to find ourselves grappling with international crises in which art is the issue: the imbroglio involving the Sony movie “The Interview,” the massacre at Charlie Hebdo in Paris. The incomprehension, whether bemused or horrified, that we feel toward people who take up arms against the creators of cartoons or comedies is a chastening reminder that there are still cultures in which art is not a harmless diversion or commodity, but something real and volatile, a potential threat to be violently suppressed. These attacks are, in a way, a savage, atavistic show of respect.

What's ConflictMap? This site aims to help shed light on wars and other armed conflicts around the globe. It contains summary information, links to more resources, and, most importantly, continuously updated lists of relevant news articles. We hope to make it easier to learn where wars are happening, who's involved, and what's going on right now, especially for smaller conflicts that may not be well covered in large media outlets. For those with a specific interest in conflicts, we hope to make it easier to follow the large volume of news in this field.

Writing about your feelings, a practice long embraced by teenagers and folk singers, is now attracting attention as a path to good health. And a recent study suggests that reflecting on your emotions could help you get over a breakup. But, one of its authors says, journaling can have its downsides. Is structured self-reflection, as some suggest, a healthy tuneup for the heart and head — or can it make hurt feelings worse?

I remember thinking, stuff? What stuff? How do you decide, the clock ticking? Years earlier, I’d made a list of the things I’d grab in a fire: Books. Photos. Art. Back then, objects were sacred; not people. Back then, I hadn’t experienced loss. The question isn’t, What would you grab in a fire? It’s, What has meaning in our lives?

Today, machines seem to get better every day at digesting vast gulps of information—and they remain as emotionally inert as ever. But since the nineteen-nineties a small number of researchers have been working to give computers the capacity to read our feelings and react, in ways that have come to seem startlingly human. Experts on the voice have trained computers to identify deep patterns in vocal pitch, rhythm, and intensity; their software can scan a conversation between a woman and a child and determine if the woman is a mother, whether she is looking the child in the eye, whether she is angry or frustrated or joyful. Other machines can measure sentiment by assessing the arrangement of our words, or by reading our gestures. Still others can do so from facial expressions. Our faces are organs of emotional communication; by some estimates, we transmit more data with our expressions than with what we say, and a few pioneers dedicated to decoding this information have made tremendous progress. Perhaps the most successful is an Egyptian scientist living near Boston, Rana el Kaliouby. Her company, Affectiva, formed in 2009, has been ranked by the business press as one of the country’s fastest-growing startups, and Kaliouby, thirty-six, has been called a “rock star.” There is good money in emotionally responsive machines, it turns out. For Kaliouby, this is no surprise: soon, she is certain, they will be ubiquitous.

Could studying ants reveal clues to reducing highway traffic jams? Physicist Apoorva Nagar at the Indian Institute of Space Science and Technology thinks the answer is yes. Nagar says he got interested in the topic when he came across a study by German and Indian researchers showing that ants running along a path were able to maintain a steady speed even when there were a large number of ants on the path. Nagar says there are three main reasons ants don't jam up. Number one, ants don't have egos. They don't show off by zooming past people. "The second thing is, they do not mind a few accidents, or collisions," say Nagar. So unless there's a serious pileup, they just keep going.

The third reason, he says, is that ants seem to get more disciplined when paths get crowded, running in straighter lines, and varying their speed less. They're less likely to make unexpected moves in this sort of heavy traffic. It's the kind of steady control you see when a computer is controlling a car rather than a human. There's less variability unless it's absolutely called for. Nagar felt this kind of behavior could be explained by something called the Langevin equation, an equation physicists use when describing the movement of liquids, or how individual atoms behave in a lattice.

After the Charlie Hebdo attack, a Paris imam went to the scene and condemned the murders. "These victims are martyrs, and I shall pray for them with all my heart," said Hassen Chalghoumi (above). He was also quoted as saying that 95% of victims of terrorism are Muslim. How accurate is this statistic?

The drone operator who said 'No' 21 January 2015 Last updated at 00:57 GMT For almost five years, Brandon Bryant worked in America's secret drone programme bombing targets in Afghanistan and elsewhere.He was told that he helped to kill more than 1,600 people, but as time went by he felt uneasy with what he was doing. He found it hard to sleep and started dreaming in infra-red. Brandon Bryant told Witness about his doubts and the mission that convinced him it was time to stop. Witness is a World Service programme of the stories of our times told by the people who were there.

The surge of emotion that makes memories of embarrassment, triumph and disappointment so vivid can also reach back in time, strengthening recall of seemingly mundane things that happened just beforehand and that, in retrospect, are relevant, a new study has found.The report, published Wednesday in the journal Nature, suggests that the television detective’s standard query — “Do you remember any unusual behavior in the days before the murder?” — is based on solid brain science, at least in some circumstances.The findings fit into the predominant theory of memory: that it is an adaptive process, continually updating itself according to what knowledge may be important in the future.The new study suggests that human memory has, in effect, a just-in-case file, keeping seemingly trivial sights, sounds and observations in cold storage for a time in case they become useful later on.
