Here’s How America Uses Its Land Using surveys, satellite images and categorizations from various government agencies, the U.S. Department of Agriculture divides the U.S. into six major types of land. The data can’t be pinpointed to a city block—each square on the map represents 250,000 acres of land. But piecing the data together state-by-state can give a general sense of how U.S. land is used. Gathered together, cropland would take up more than a fifth of the 48 contiguous states. Pasture and rangeland would cover most of the Western U.S., and all of the country’s cities and towns would fit neatly in the Northeast. The Mounting Evidence Against Ultra-Processed Foods About 60 percent of Americans’ total daily calories come from ultra-processed food, according to study researchers, so there is room for improvement. “It’s not that you have to cut them out of your diet completely—it appears that health risks start cropping up once you begin eating more than two servings a day,” Lawrence says. “Like everything else in life, it’s about moderation.” Here are five easy ways to reduce your intake.
Climate Undermined by Lobbying For all the evidence that the benefits of reducing greenhouse gases outweigh the costs of regulation, disturbingly few domestic climate change policies have been enacted around the world so far. So say UC Santa Barbara professor and economist Kyle Meng, and co-author Ashwin Rode, a former UCSB Ph.D. student now at the University of Chicago, in a paper published in the journal Nature Climate Change. “There is a striking disconnect between what is needed to avoid dangerous climate change and what has actually been done to date,” said Meng, a professor in the Bren School of Environmental Science & Management and in the Department of Economics. One common explanation for that disconnect, he added, is that jurisdictions are reluctant to adopt climate policy when they can simply benefit from the reductions implemented by other jurisdictions. However, say Meng and Rode, the political process that leads to climate change regulation can be a barrier to its own legislation.

People in higher social class have an exaggerated belief that they are better than others WASHINGTON -- People who see themselves as being in a higher social class may tend to have an exaggerated belief that they are more adept than their equally capable lower-class counterparts, and that overconfidence can often be misinterpreted by others as greater competence in important situations, such as job interviews, according to research published by the American Psychological Association. "Advantages beget advantages. Those who are born in upper-class echelons are likely to remain in the upper class, and high-earning entrepreneurs disproportionately originate from highly educated, well-to-do families," said Peter Belmi, PhD, of the University of Virginia and lead author of the study. "Our research suggests that social class shapes the attitudes that people hold about their abilities and that, in turn, has important implications for how class hierarchies perpetuate from one generation to the next."
How philosophy helped one soldier on the battlefield When I attended the Royal Military Academy Sandhurst in 2002-3, the leadership training was excellent. It included discussion of the British Army’s values and the laws of armed conflict. However, I received no ethics training for the occasions when neither values nor laws would fully prepare me to make complex moral decisions in faraway fields populated by people with very different cultural norms. The then prime minister Tony Blair spoke at our pass-out parade just weeks after the invasion of Iraq. Dignitaries usually stop at every third or fourth person on parade to have a few words. Download 91,000 Historic Maps from the Massive David Rumsey Map Collection Three years ago, we highlighted one of the most comprehensive map collections in existence, the David Rumsey Map Collection, then newly moved to Stanford University. The Rumsey Collection, we wrote then, “contains a seemingly inexhaustible supply of cartographic images”—justifiable hyperbole, considering the amount of time it would take any one person to absorb the over 150,000 physical artifacts Rumsey has amassed in one place. By 2016, Rumsey had made almost half the collection—over 67,000 images—freely available in a digital archive that has been growing since 1996. Each entry features high-resolution scans for specialists (you can download them for free) and more manageable image sizes for enthusiasts; a wealth of data about provenance and historical context; and digital, user-friendly tools that use crowd-sourcing to measure the accuracy of antiquated maps against GPS renderings.
Is the U.S. a Democracy? A Social Studies Battle Turns on the Nation’s Values LANSING, Mich. — Bruising political fights are usual business in Becky Debowski’s eighth-grade social studies classroom. From a model Constitutional Convention to a bare-knuckle debate in Congress over slavery, she regularly has students assume roles of partisans throughout American history, like Abraham Lincoln and John C. Calhoun. After the exercises, the class comes back together to debate whether the nation lived up to what the state of Michigan calls “core democratic values,” such as equality, liberty and diversity.
There's A Reason Why You Still Love The Music From Your Teen Years It's probably the latter. Psychologists and neuroscientists have recently determined that musical nostalgia isn't just a cultural phenomenon—it's wired in our brains. Even when your tastes progress past the Backstreet Boys, your brain is stuck on the formative years of your adolescence. The Doomsday Doctrine This week we’re thinking about Nuclear Doomsday. But why worry about a nuclear doomsday now? The Cold War is over. At its height we had thirty thousand warheads pointed at the Soviets, they had forty thousand pointed at us – but we’re each down to a fraction of that. A climate doomsday seems much more likely. For one thing, there are still enough nuclear weapons in each arsenal to incinerate the earth, cause a nuclear winter, and extinguish practically all life on earth.
